    Advanced gastric cancer in the lower third of the stomach often results in stricture of the gastric cavity and digestive symptoms. Gastrojejunostomy has been suggested to improve such symptoms, and the advent of new anticancer agents for gastric cancer has improved the response rate of the disease, which makes it possible to perform R0 gastrectomy in part of patients with stage IV gastric cancer. We experienced a rare case in which a patient with stage IV gastric cancer and cancerous pyloric stenosis was treated with R0 surgery after undergoing a gastrojejunal bypass procedure and multidisciplinary treatment. There have not been any previous reports about cases in which a previous gastrojejunostomy was utilized as a reconstruction route during distal gastrectomy in a patient with gastric cancer that had been treated with chemotherapy and/or CRT. An 80-year-old female with advanced gastric cancer and pyloric stenosis was admitted to Kagoshima University Hospital. As peritoneal washing cytology produced a positive result, laparoscopic gastrojejunostomy (modified Devine procedure) was performed to improve food passage, and S-1 (100 mg/body, days 1-14) plus paclitaxel (120 mg/body, days 1 and 15) was administered. Although the tumor was temporarily reduced in size, an abdominal computed tomography scan obtained after four courses of chemotherapy showed progressive disease. Thus, chemoradiotherapy (56 Gy, S-1: 60 mg/body, CDDP: 5 mg/body, days 1-5) was indicated. Marked tumor shrinkage and negative peritoneal washing cytological results were achieved. Curative gastrectomy with D2 lymphadenectomy was performed. We carried out distal gastrectomy and lymph node dissection, and the gastrojejunostomy produced as a gastric bypass in the previous operation was preserved. The patient has not suffered a tumor relapse in 4 years since the surgery. We surgeons increase a chance to perform R0 gastrectomy for stage IV gastric cancer following intensive chemotherapy and/or CRT

    Abstract Even though more than a century later, after the first case of gastrectomy has been successfully performed, the best surgical treatment for distal gastric cancer still remains controversial. Thus, the present study was designed to compare the survival impact of distal (DG) or total gastrectomy (TG) for distal gastric cancer. A total of 1262 distal gastric cancer patients were enrolled in current study including 1157 patients who underwent DG and 157 patients who underwent TG. The postoperative complications and 5-year overall survival were compared between the 2 groups. TG group presented a longer surgical time, a higher volume of intraoperative bleeding, and a larger number of excised lymph nodes (all P < 0.05) compared with the DG group. The postoperative complications were comparable (all P >0.05). The 5-year overall survival rate of DG group was significantly higher than that of TG group (67.6% vs 44.3%, P < 0.001). However, multivariate analysis showed that type of resection was not an independent prognostic factor for distal gastric cancer (P > 0.05). The factor-stratified multivariate analysis showed that only in the subgroup of Tumor-node-metastasis staging system (TNM) stage III (P = 0.049), TG was the independent prognostic factor for poor survival. In conclusion, DG was as feasible as TG; however, TG did not increase the survival rate. DG brought better long-term survival than TG in patients with TNM stage III tumor. We recommended that DG should be the optimal surgical procedure for distal gastric cancer under the premise of negative resection margin. PMID:28151896

    To compare the postoperative quality of life of vagus nerve preserving distal gastrectomy (VPG) vs conventional distal gastrectomy (CG) in patients with early-stage gastric cancer. Randomized controlled clinical trial. Large tertiary comprehensive cancer center in Korea. One hundred sixty-three patients with early gastric cancer 18 years of age or older expected to undergo curative gastric resection. Patients were randomized 1:1 to VPG (n = 85) or CG (n = 78). European Organization for Research and Treatment of Cancer (EORTC) gastric module (STO22). Patients assigned to VPG showed less diarrhea 3 and 12 months after surgery (P = 0.040 and 0.048, respectively) and less appetite loss at 12 months (P = 0.011) compared with those assigned to CG. In both groups, fatigue, anxiety, eating restriction, and body image deteriorated at 3 months after surgery and did not regain baseline levels 12 months after surgery. There were no significant differences between the 2 groups in cancer recurrence and death over 5 years of follow-up. Early gastric cancer patients undergoing VPG reported significantly less diarrhea and appetite loss at 12 months postsurgery compared with those undergoing CG, with no differences in long-term clinical outcomes. VPG may improve the quality of life after gastrectomy in early gastric cancer patients compared with CG.

  4. Visceral fat changes after distal gastrectomy according to type of reconstruction procedure for gastric cancer

    Background Noncancerous causes of death, such as cerebrovascular or cardiac disease, are not rare in patients with gastric cancer who had undergone curative gastrectomy. Metabolic syndrome, characterized by visceral fat accumulation, is a risk factor for cerebrovascular and cardiac diseases. However, there is limited information on the effects of reconstruction procedures on changes in visceral fat after distal gastrectomy. The aim of this study was to analyze the impact of the reconstruction procedure (Roux-en-Y reconstruction (RY) and Billroth I reconstruction (BI)) on changes in visceral fat, as determined using computed tomography. Methods The study subjects were 152 patients with gastric cancer who underwent distal gastrectomy with lymphadenectomy between 2002 and 2007. The visceral fat area was measured for one cross-sectional computed tomogram obtained at the level of the umbilicus. Results Adjuvant chemotherapy (yes vs. no, P = 0.0006), type of reconstruction (BI vs. RY, P = 0.0146), field of lymph node dissection (distal gastrectomy on visceral fat. PMID:23786988

    AIM: To study the relationship between platelet count-to-spleen diameter ratio and post-gastrectomy esophageal varices (EVs) development in patients without liver cirrhosis or hepatitis. METHODS: We retrospectively studied 92 patients who underwent gastrectomy. They were divided into 2 groups on the basis of the surgical treatment: the distal gastrectomy (DG) group and total gastrectomy (TG) group. The incidence of EVs was determined and postoperative platelet counts, spleen diameters, and platelet count-to-spleen diameter ratios were compared between the 2 groups. RESULTS: EVs were not detected during the first 6 mo after surgery in either group; however, at 12 mo after surgery, EVs were detected in 2 patients (3%) in the DG group and in 1 patient (3.6%) in the TG group; their mean platelet count-to-spleen diameter ratio was 2628 ± 409, and 2604 ± 360, respectively. CONCLUSION: Endoscopy should be performed to detect EVs when the platelet count-to-spleen diameter ratio is < 2600. PMID:20533601

    Abstract The objective of this study was to compare long-term surgical outcomes and complications of laparoscopy-assisted distal gastrectomy (LADG) with open distal gastrectomy (ODG) for the treatment of early gastric cancer (EGC) based on a review of available randomized controlled trials (RCTs) evaluated using the Cochrane methodology. RCTs comparing LADG and ODG were identified by a systematic literature search in PubMed, Cochrane Library, MEDLINE, EMBASE, Scopus, and the China Knowledge Resource Integrated Database, for papers published from January 1, 2003 to July 30, 2015. Meta-analyses were performed to compare the long-term clinical outcomes. Our systematic literature search identified 8 eligible RCTs including 732 patients (374 LADGs and 358 ODGs), with low overall risk of bias. Long-term mortality and relapse rate were comparable for both techniques. The long-term complication rate was 8.47% in LADG groups and 13.62% in the ODG group, indicating that LADG was associated with lower risk for long-term complications (RR = 0.63; 95%CI = 0.39–1.00; P = 0.03). In the treatment of EGC, LADG lowered the rate of long- and short-term complications and promoted earlier recovery, with comparable oncological outcomes to ODG. PMID:27399073

    This study compared surgical outcomes between patients undergoing laparoscopy-assisted distal gastrectomy (LADG) and those undergoing open distal gastrectomy (ODG) from the viewpoint of obesity. Between June 2002 and May 2008, 146 patients with preoperatively diagnosed early gastric cancer who underwent LADG (n = 90) or ODG (n = 56) were enrolled in this study and compared in terms of clinicopathological findings and operative outcome. The visceral fat area (VFA) and subcutaneous fat area (SFA) were assessed as identifiers of obesity using FatScan software. The relationship between obesity and operative outcomes after LADG and ODG was evaluated. There were no significant correlations between intraoperative blood loss (IBL) and any obesity-related factors, or between operation time (OT) and any obesity-related factors in the LADG group. There was a significant correlation between IBL and BMI (r = 0.486, P = 0.0001), IBL and VFA (r = 0.456, P = 0.0003), IBL and SFA (r = 0.311, P = 0.0193), OT and BMI (r = 0.406, P = 0.0017), OT and VFA (r = 0.314, P = 0.0178), and between OT and SFA (r = 0.382, P = 0.0034) in the ODG group. LADG may be a useful operative manipulation that is not influenced by obesity, whereas ODG may be influenced by obesity even after reaching the surgical plateau. (c) 2010 Wiley-Liss, Inc.

    To report the initial experience with the laparoscopy-assisted distal gastrectomy (LADG) with D2 lymphadenectomy for gastric cancer. Between May 2006 and May 2007, 29 consecutive GC patients with gastric cancer underwent LADG with D2 lymphadenectomy. The operation consisted in a laparoscopic time to perform lymphadenectomy and mobilization of the distal stomach, followed by a minilaparotomy for exteriorization of the specimen and construction of a hand sewn anastomosis. Twenty-nine patients underwent LADG with D2 lymphadenectomy for gastric cancer. Mean age was 58.2 years. Mean operative time was 287.4 min. Mean number of lymph nodes resected was 42.6. Twelve patients were early gastric cancer, and seventeen were advanced gastric cancer. Mean proximal and distal resection margin were 5.8 cm and 3.5 cm, respectively. Resection margins were negative in all cases. Mean number of lymph nodes resected was 42.6. Thirty-day morbidity rate was 10.3 %. There were no postoperative deaths.CONCLUSION. The short-term results of our LADG with D2 lymphadenectomy for the treatment of gastric cancer shows that a radical surgery, in terms of resection margins and lymphadenectomy, can be done with low morbidity.

    Remnant gastric cancer (RGC) and gastric stump cancer after distal gastrectomy (DG) are recognized as the same clinical entity. In this review, the current knowledges as well as the non-settled issues of RGC are presented. Duodenogastric reflux and denervation of the gastric mucosa are considered as the two main factors responsible for the development of RGC after benign disease. On the other hand, some precancerous circumstances which already have existed at the time of initial surgery, such as atrophic gastritis and intestinal metaplasia, are the main factors associated with RGC after gastric cancer. Although eradication of Helicobacter pylori (H. pylori) in remnant stomach is promising, it is still uncertain whether it can reduce the risk of carcinogenesis. Periodic endoscopic surveillance after DG was reported useful in detecting RGC at an early stage, which offers a chance to undergo minimally invasive endoscopic treatment or laparoscopic surgery and leads to an improved prognosis in RGC patients. Future challenges may be expected to elucidate the benefit of eradication of H. pylori in the remnant stomach if it could reduce the risk for RGC, to build an optimal endoscopic surveillance strategy after DG by stratifying the risk for development of RGC, and to develop a specific staging system for RGC for the standardization of the treatment by prospecting the prognosis.

    Omental infarction occurring after open and laparoscopic-assisted distal gastrectomy with partial omentectomy for gastric cancer was a very rare disease in the past, but its incidence has increased as more partial omentectomies are now being performed. But there are few case reports or radiologic studies on its increasing incidence. It is necessary to differentiate omental infarction from carcinomatosis peritonei, since both have similar imaging findings. In this report, we describe two cases of omental infarction; each occurred after open and laparoscopic-assisted distal gastrectomy in early gastric cancer patients. Partial omentectomy was performed in both cases. Omental infarction following distal gastrectomy with partial omentectomy can be discriminated from carcinomatosis peritonei by comparing with different initial and follow up CT findings.

    The optimal surgical procedure for gastric remnant carcinoma (GRC) remains debatable. The aim of this study was to retrospectively evaluate the surgical treatments for T2-4 GRC developing after distal gastrectomy for gastric cancer. Between 1970 and 2012, a total of 50 patients underwent R0 resection for T2-4 GRC. The clinicopathologic features, therapeutic methods, and follow-up data of these patients were reviewed. The tumor was located at a non-anastomotic site of the remnant stomach in 43 of the 50 patients. Total gastrectomy was performed in 48 patients and partial gastrectomy was in two patients. Lymph node metastasis was found in 19 patients. Major postoperative complications occurred in 16 patients. The overall 1-, 3-, and 5-year survival rates of the 50 patients were 90%, 66%, and 44%, respectively. Presence of small intestinal or esophageal infiltration and postoperative complications was independently associated with poorer survival. Dissection of the perigastric and splenic hilar/artery nodes was found to have potential therapeutic benefit. Surgical resection for T2-4 GRC developing after distal gastrectomy for gastric cancer can be invasive, but is feasible and effective. Total gastrectomy with splenectomy is one of the recommendable procedures for this disease. © 2014 Wiley Periodicals, Inc.

    Many surgeons in Japan use 1-day nasogastric tube (NGT) decompression after gastrectomy as a standard procedure. This prospective randomized study aimed to define whether 1-day NGT decompression is necessary after distal gastrectomy. The subjects were 233 patients with gastric cancer, randomized into two groups immediately after distal gastrectomy: one group received 1-day NGT decompression (NGT group, n = 119) and the other did not (no-NGT group, n = 114). The primary outcome measure was postoperative surgery-related and respiratory complications, whereas secondary measures were the postoperative course to recovery and patient complaints. The incidence of surgery-related complications did not differ significantly between the NGT and no-NGT groups (21.0 and 19.2%, respectively; p = 0.87). The rate of respiratory complications was 6.7% in the NGT group and 7.0% in the no-NGT group (p > 0.99). The time to passage of first flatus and the postoperative hospital stay did not differ between the groups. Twenty-five patients in the NGT group and none in the no-NGT group complained of nasopharyngeal discomfort (p < 0.0001). Considering the physical discomfort caused by the NGT, we believe that routine 1-day NGT decompression is unnecessary after distal gastrectomy.

    Perforated peptic ulcer disease remains a relatively frequent emergency surgery presentation. Persistent leak is the most common indication for return to theatre. We present a technique to manage patients in whom a more substantial resection is not possible. A 45-year-old woman underwent initial laparoscopic primary closure of a non-malignant perforated gastric ulcer. This subsequently leaked on return to the UK and had a further graham patch formed via a laparotomy. Unfortunately, the patch repair leaked and at reoperation a wedge excision or distal gastrectomy was not possible given the friability of the tissues and instability of the patient, a transgastric drain and perigastric drain were therefore placed. This created a controlled fistula, which was managed eventually as an outpatient. Transgastric drains in the context of the persistent perforated gastric ulcer leak are a safe way to manage the unstable patient with poor tissues where more substantial surgeries such as a distal gastrectomy are not possible.

    Schwannomas are rarely observed in the gastrointestinal tract. The most common symptoms of a gastric schwannoma are abdominal pain or dyspepsia, gastrointestinal bleeding, and an abdominal mass. Many gastric schwannomas are asymptomatic and are discovered incidentally or at postmortem. The diagnosis of a schwannoma is based on immunohistochemical positivity for S-100 protein. We present a case report of a rare complication of gastric schwannoma causing gastroduodenal intussusception that was successfully managed by a Billroth II distal gastrectomy. In this rare case, the patient had intermittent, colicky abdominal pain, nausea, and vomiting for over 4 wk accompanied by a weight loss. A diagnosis of gastric intussusception was made by computed tomography. A Billroth II distal gastrectomy was then performed, and complete en bloc removal (R0 resection) was achieved. Pathology confirmed a gastric schwannoma through positive immunohistochemical staining for S-100 protein.

    BACKGROUND: We aimed to clarify the utility of delta-shaped anastomosis (Delta), an intracorporeal Billroth-I anastomosis-based reconstruction technique used after laparoscopy-assisted distal gastrectomy (LADG), in robot-assisted distal gastrectomy (RADG). METHODS: RADG was performed in patients with clinical Stage I gastric cancer, and reconstruction was performed using Delta. The Delta procedure was the same as that performed after LADG, and the operator practiced the procedure in simulated settings with surgical assistants before the operation. After gastrectomy, the scope and robotic first arm were reinserted from separate ports on the right side of the patient. Then, a port on the left side of the abdomen was used as the assistant port from which a stapler was inserted, with the robotic arm in a coaxial mode. The surgical assistant performed functional end-to-end anastomosis of the remnant stomach and duodenal stump using a powered stapler. RESULTS: The mean anastomotic time in four patients who underwent Delta after RADG was 16.5 min. All patients were discharged on the post-operative day 7 without any post-operative complications or need for readmission. CONCLUSIONS: Pre-operative simulation, changes in ports for insertion of the scope and robotic first arm, continuation of the coaxial operation, and use of a powered stapler made Delta applicable for RADG. Delta can be considered as a useful reconstruction method. PMID:28607290

    Body weight loss is a common but one of the most serious sequelae after gastrectomy. Ghrelin, a novel gastric hormone that up-regulates body weight through appetite control and metabolic reaction, seems to be affected by gastric surgery. Early postoperative alteration of serum ghrelin was evaluated at days 3 and 7 after gastrectomy for 13 hospital patients. In 64 outpatients who had previously undergone total gastrectomy (TG: 26 patients) or distal gastrectomy (DG: 38 patients) 4.6 months to 136 months (average, 41 months) earlier, the association between their serum ghrelin and leptin levels and postoperative body weight was investigated. Serum ghrelin declined immediately and greatly after TG to 12% of the preoperative level (day 3 and day 7), whereas the decline was less significant after DG at 39% (day 3) and 56% (day 7). In outpatients, serum ghrelin after TG was very low compared with the control (18.6 fmol/mL versus 92.1 fmol/mL, P<0.0001), irrespective of the period after surgery, whereas the level after DG recovered and was equivalent to the control (73.4 fmol/mL, P=0.355). Body weight loss was more apparent in TG patients than in DG patients, showing postoperative reduction of body mass index (DeltaBMI) -3.940 versus -1.949 (P<0.0001). Serum leptin concentration, reflecting the systemic fat volume, significantly correlated with BMI in both TG and DG patients, and tended to be lower in TG patients than in DG patients (800 pg/mL versus 1158 pg/mL, P=0.236). Persistent decline of serum ghrelin and body weight was observed commonly after total gastrectomy. Further study is needed as to whether or not ghrelin administration can improve the body weight level for these patients.

    Esophagojejunal anastomosis fistula is the main complication after a total gastrectomy. To avoid a complex procedure on friable inflamed perianastomotic tissues, a coated self-expandable stent is mounted at the site of the anastomotic leak. A complication of stenting procedure is that it might lead to distal esophageal stenosis. However, another frequently encountered complication of stenting is stent migration, which is treated nonsurgically. When the migrated stent creates life threatening complications, surgical removal is indicated. We present a case of a 67-year-old male patient who was treated at our facility for a gastric adenocarcinoma which developed, postoperatively, an esophagojejunostomy fistula, a distal esophageal stenosis, and a metallic coated self-expandable stent migration. To our knowledge, this is the first reported case of an esophagojejunostomy fistula combined with a distal esophageal stenosis as well as with a metallic coated self-expandable stent migration.

This study examined whether myoelectric activity varied with surgical technique and compared vagus nerve-preserving distal gastrectomy (VP-DG) with standard distal gastrectomy without vagus nerve preservation (DG). Furthermore, we examined the relationship between the M-EGG findings and patients' postoperative symptoms. Methods Twenty-six patients who underwent VP-DG, 20 who underwent DG, and 12 healthy volunteers as controls were examined with M-EGG. The Gastrointestinal Symptom Rating Scale (GSRS) was used to assess postoperative symptoms. Results Longer periods of normal gastric function (normogastria, 2.0–4.0 cycle min–1) were detected in channel 1 in the VP-DG group than in the DG group in either the fasted or fed state (P<0.05). The percentage of slow wave coupling (%SWC) in the fed state correlated negatively with GSRS scores (reflux, r=–0.59, P=0.02; abdominal pain, r=–0.51, P=0.04, indigestion, r=–0.59, P=0.02 and total score, r=–0.75, P=0.02). Conclusions Slow waves can be recorded non-invasively using M-EGG in the remnant stomach following gastrectomy. The VP-DG group showed better preserved gastric myoelectric activity than the DG group, and the %SWC showed a significant negative correlation with scores of GSRS (reflux, abdominal pain, indigestion and total score) in the VP-DG group.

    We report our experience with two cases of situs inversus totalis, both involving patients diagnosed with gastric cancer. These were a 52-year-old male with a preoperative staging of cT1bN0M0 and a 68-year-old male with a staging of cT2N0M0, both of whom underwent surgery. The former was found to have vascular anomalies in the preoperative computed tomography, so we performed a computed tomography angiography with three-dimensional reconstruction. Laparoscopy-assisted distal gastrectomy with Billroth I anastomosis was performed with D1+ lymph node dissection, and a small laparotomy was made for extracorporeal anastomosis. In contrast, the latter case showed no vascular anomalies in the preoperative computed tomography, and totally laparoscopic distal gastrectomy with delta anastomosis was performed with D1+ lymph node dissection. There were no intraoperative problems in either patient and they were discharged without postoperative complications. Histopathological examination revealed a poorly differentiated adenocarcinoma (pT2N0M0) and a well-differentiated adenocarcinoma (pT1aN0M0), respectively. PMID:24511424

    Purpose Acupuncture has recently been accepted as a treatment option for managing postoperative ileus (POI) and various functional gastrointestinal disorders. Therefore, we conducted a prospective randomized study to evaluate the effect of acupuncture on POI and other surgical outcomes in patients who underwent gastric surgery. Materials and Methods Thirty-six patients who underwent distal gastrectomy for gastric cancer from March to December 2015 were randomly assigned to acupuncture or non-acupuncture (NA) groups at 1:1 ratio. The acupuncture treatment was administered treatment once daily for 5 consecutive days starting at postoperative day 1. The primary outcome measure was the number of remnant sitz markers in the small intestine on abdominal radiograph. The secondary outcome measure was the surgical outcome, including the times to first flatus, first defecation, start of water intake, and start of soft diet, as well as length of hospital stay and laboratory findings. Results The acupuncture group had significantly fewer remnant sitz markers in the small intestine on postoperative days 3 and 5 compared to those in the NA group. A significant difference was observed in the numbers of remnant sitz markers in the small intestine with respect to group differences by time (P<0.0001). The acupuncture group showed relatively better surgical outcomes than those in the NA group, but the differences were not statistically significant. Conclusions In this clinical trial, acupuncture promoted the passage of sitz markers, which may reflect the possibility of reducing POI after distal gastrectomy. PMID:28337359

    The aim of the study was to compare the clinical symptoms between Billroth II (B-II) and Roux-en-Y (R-Y) reconstruction after distal subtotal gastrectomy (DG) for gastric cancer. Surgery is the mainstay of curative treatment for gastric cancer. The technique for reconstruction after DG remains controversial. Both B-II and R-Y are popular methods. This is a prospective multicenter randomized controlled trial. From October 2008 to October 2014, 162 patients who underwent DG were randomly allocated to B-II (n = 81) and R-Y (n = 81) groups. The primary endpoint is Gastrointestinal (GI) Symptoms Score 1 year after surgery. We also compared the nutritional status, extent of gastritis on endoscopy, and quality of life after surgery between the 2 procedures at 1 year. Operative time was significantly shorter for B-II than for R-Y [mean difference 21.5 minutes, 95% confidence interval (95% CI) 3.8-39.3, P = 0.019]. The B-II and R-Y groups had a peri-operative morbidity of 28.4% and 33.8%, respectively (P = 0.500) and a 30-day mortality of 2.5% and 1.2%, respectively (P = 0.500). GI symptoms score did not differ between R-Y versus B-II reconstruction (mean difference -0.45, 95% CI -1.21 to 0.31, P = 0.232). R-Y resulted in a lower median endoscopic grade for gastritis versus B-II (mean difference -1.32, 95% CI -1.67 to -0.98, P < 0.001). We noted no difference in nutritional status (R-Y versus B-II mean difference -0.31, 95% CI -3.27 to 2.65, P = 0.837) and quality of life at 1 year between the 2 groups too. Although BII is associated with a higher incidence of heartburn symptom and higher median endoscopic grade for gastritis, BII and RY are similar in terms of overall GI symptom score and nutritional status at 1 year after distal gastrectomy.

    Negative Helicobacter pylori status has been identified as a poor prognostic factor for survival in gastric cancer (GC) patients who underwent surgery. The aim of this study was to examine the effect of H. pylori eradication on long-term outcomes after distal gastrectomy for GC. We analyzed the survival of 169 distal GC patients enrolled in a prospective randomized trial evaluating histologic changes of gastric mucosa after H. pylori eradication in the remnant stomach. The outcomes measured were overall survival (OS) and GC recurrence rates. The median follow-up duration was 9.4 years. In the modified intention-to-treat analysis including patients who underwent H. pylori treatment (n=87) or placebo (n=82), 5-year OS rates were 98.9% in the treatment group and 91.5% in the placebo group, and Kaplan-Meier analysis showed no significant difference in OS (p=0.957) between groups. In multivariate analysis, no difference in overall mortality was observed between groups (adjusted hazard ratio [aHR] for H. pylori treatment, 0.75; p=0.495) or H. pylori-eradicated status (aHR for positive H. pylori status, 1.16; p=0.715), while old age, male sex, and advanced stage ≥ IIIa were independent risk factors. Six patients in the treatment group (6.9%) and seven patients in the placebo group (8.5%) had GC recurrences, and GC recurrence rates were not different according to H. pylori treatment (5-year GC recurrence rates, 4.6% in the treatment group vs. 8.5% in the placebo group; p=0.652). H. pylori eradication for GC patients who underwent distal gastrectomy did not compromise long-term survival after surgery.

    Despite the increasing prevalence of obesity and gastric diseases, the impact of obesity on short- and long-term outcomes of laparoscopic distal gastrectomy for gastric cancer still remains unclear. Sixty-one consecutive obese patients with body mass index (BMI)≥30 kg/m(2), who underwent laparoscopic distal gastrectomy, were compared with 76 non-obese patients with BMI<30 kg/m(2). Short- and long-term outcomes were analyzed in both groups. Obesity was associated with a longer operative time and a greater estimated blood loss. The rate of conversion to open distal gastrectomy was similar between the two groups. There were no 30-day postoperative deaths in either group. There was no significant difference in the overall number or severity of 30-day postoperative complications between the two groups. Regarding long-term survival outcomes, there was no statistical difference in overall (OS) or disease-free survival (DFS) between the two groups. Multivariate analysis showed that BMI did not influence prognosis. Laparoscopic distal gastrectomy appears to be a safe and reasonable option for selected obese patients with gastric cancer and results in short- and long-term outcomes similar to those in non-obese patients.

    To discuss laparoscopic assisted radical D2 resection of distal gastric anatomy application ideas. Collected the clinical data from January 2009 to January 2012 who underwent laparoscopic distal gastric resection in patients with D2 349 cases. There were 180 male and 169 female patients, and the age were (57 ± 3) years old (range 29-86 years), the body mass index of patients were (26.0 ± 2.0) kg/m(2) (range 20.5-32.8 kg/m(2)). The relevant surgical anatomy ideas had summarized. In addition to 5 cases of obese patients with conversion to open, the remaining patients underwent laparoscopic distal gastric D2 resection. The operation is divided into 7 operating anatomical view. The operation time were 120-210 minutes and the blood loss were 50-200 ml. Postoperative complications occurred in 11 cases, including 5 cases of duodenal stump leakage, 2 cases of gastroparesis, 3 cases of small bowel obstruction, and abdominal bleeding in 1 case. All patients were discharged. Use zoning, exterior to interior of the anatomy, more conducive to master the operation of laparoscopic radical gastrectomy and standardized cleaning, to improve the operation efficiency and shorten the surgical learning curve and improve the quality of surgery has an important role.

    To elucidate the potential impact of the grade of complications on long-term survival of gastric cancer patients after curative surgery. A total of 751 gastric cancer patients who underwent curative gastrectomy between January 2002 and December 2006 in our center were enrolled in this study. Patients were divided into four groups: no complications, Grade I, Grade II and Grade III complications, according to the following classification systems: T92 (Toronto 1992 or Clavien), Accordion Classification, and Revised Accordion Classification. Clinicopathological features were compared among the four groups and potential prognostic factors were analyzed. The Log-rank test was used to assess statistical differences between the groups. Independent prognostic factors were identified using the Cox proportional hazards regression model. Stratified analysis was used to investigate the impact of complications of each grade on survival. Significant differences were found among the four groups in age, sex, other diseases (including hypertension, diabetes and chronic obstructive pulmonary disease), body mass index (BMI), intraoperative blood loss, tumor location, extranodal metastasis, lymph node metastasis, tumor-node-metastasis (TNM) stage, and chemotherapy. Overall survival (OS) was significantly influenced by the complication grade. The 5-year OS rates were 43.0%, 42.5%, 25.5% and 9.6% for no complications, and Grade I, Grade II and Grade III complications, respectively (P < 0.001). Age, tumor size, intraoperative blood loss, lymph node metastasis, TNM stage and complication grade were independent prognostic factors in multivariate analysis. With stratified analysis, lymph node metastasis, tumor size, and intraoperative blood loss were independent prognostic factors for Grade I complications (P < 0.001, P = 0.031, P = 0.030). Age and lymph node metastasis were found to be independent prognostic factors for OS of gastric cancer patients with Grade II complications (P

    Purpose Mechanical stapler is regarded as a good alternative to the hand sewing technique, when used in gastric reconstruction. The circular stapling method has been widely applied to gastrectomy (open orlaparoscopic), for gastric cancer. We illustrated and compared the hand-sutured method to the circular stapling method, for Billroth-II, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. Materials and Methods Between April 2009 and May 2011, 60 patients who underwent laparoscopy assisted distal gastrectomy, with Billroth-II, were enrolled. Hand-sutured Billroth-II was performed in 40 patients (manual group) and circular stapler Billroth-II was performed in 20 patients (stapler group). Clinicopathological features and post-operative outcomes were evaluated and compared between the two groups. Results Nosignificant differences were observed in clinicopathologic parameters and post-operative outcomes, except in the operation times. Operation times and anastomosis times were significantly shorter in the stapler group (P=0.004 and P<0.001). Conclusions Compared to the hand-sutured method, the circular stapling method can be applied safely and more efficiently, when performing Billroth-II anastomosis, after laparoscopy assisted distal gastrectomy in patients with gastric cancer.

    To evaluate the safety, feasibility and the long-term outcomes of laparoscopy-assisted gastrectomy (LAG) for advanced gastric cancer (AGC). The clinical and follow-up data of 46 cases after LAG from June 2008 to December 2009 were analyzed, and compared with 85 cases after conventional open gastrectomy (OG) for advanced gastric cancer at the same period at our hospital. The surgical safety, postoperative recovery, complications, radical degree, survival rate were compared. As compared with OG group, operation time was longer in LATG group ((274 ± 78) min vs. ( 217 ± 41) min, t = 4.635, P = 0.000). Estimated blood loss in the LAG group ((254 ± 112) ml) was significantly less than in the OG group (t = 3.942, P = 0.000). Time to ambulation ((63 ± 16) hours), first flatus ((77 ± 20) hours), resumed liquid diet ((88 ± 15) hours), duration of analgesic medication ((53 ± 20) hours) and postoperative hospital stay ((11.1 ± 4.6) days) were significantly shorter in the LAG group (t = 5.549, 6.508, 9.436, 9.464 and 2.980 respectively, all P < 0.01). The distance of the proximal and distal resection margin were (5.7 ± 1.4) cm and (3.9 ± 1.5) cm in LAG group, (5.8 ± 1.1) cm and (4.7 ± 1.5) cm in OG group respectively, but the difference was not significant. The number of lymph node dissections was also similar, (30.5 ± 10.4) in LAG group and (32.6 ± 12.3) in OG group (t = 0.960, P = 0.339). The incidence of postoperative complications and mortality rate in LAG group (8.7% and 0 respectively) were also lower than in the OG group, with no statistically significant difference (P > 0.05). The mean follow-up was 31.0 months (range 6-48 months), and the cumulative survival of the 2 groups was similar (χ(2) = 1.594, P = 0.207). Laparoscopy-assisted gastrectomy for advanced gastric cancer is not significantly different with open surgery in surgical safety, radical degree, and survival rate. It is less traumatic and of fewer complications.

    Since a patient's obesity can affect the mortality and morbidity of the surgery, less drastic surgeries may have a major benefit for obese individuals. This study evaluated the feasibility of performing a totally laparoscopic distal gastrectomy, with intracorporeal anastomosis, in obese patients suffering from gastric cancer. This was a retrospective analysis of the 138 patients, who underwent a totally laparoscopic distal gastrectomy from April 2005 to March 2009, at the National Kyushu Cancer Center. The body mass index of 20 patients was ≥25, and in 118 patients, it was <25 kg/m(2). The mean values of body mass index in the 2 groups were 27.3±2.2 and 21.4±2.3. Hypertension was significantly more frequent in the obese patients than in the non-obese patients. The intraoperative blood loss, duration of surgery, post-operative complication rate, post-operative hospital stay, and a number of retrieved lymph nodes were not significantly different between the two groups. Intracorporeal anastomosis seemed to have a benefit for obese individuals. Totally laparoscopic gastrectomy is, therefore, considered to be a safe and an effective modality for obese patients.

    The aims of this study were to make serial comparisons of the quality of life (QoL) between patients who underwent total gastrectomy and those who underwent distal subtotal gastrectomy for gastric cancer and to identify the affected scales with consistency. QoL data of 275 patients who were admitted for surgery between September 2008 and June 2011 and who underwent subtotal gastrectomy or total gastrectomy were obtained preoperatively and postoperatively at 3, 6, 9, 12, 18, and 24 months. The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the gastric cancer specific module, the EORTC QLQ-STO22, were used to assess QoL. QoL, as assessed by the global health status/QoL and physical functioning, revealed a brief divergence with worse QoL in the total gastrectomy group 3 months postoperatively, followed by rapid convergence. QoL related to restrictive symptoms (nausea/vomiting, dysphagia, reflux, and eating restrictions) and dry mouth was consistently worse in the total gastrectomy group during the first 2 postoperative years. The general QoL of patients after gastrectomy is highly congruent with subjective physical functioning, and the differences between patients who undergo total gastrectomy and subtotal gastrectomy are no longer valid several months after surgery. In order to further reduce the differences in QoL between patients who underwent total gastrectomy and subtotal gastrectomy, definitive preoperative informing, followed by postoperative symptomatic management, of restrictive symptoms in total gastrectomy patients is the most rational approach.

    This report describes the techniques and outcomes of reduced port distal gastrectomy (RPDG) with a multichannel port plus one puncture (POP) for gastric cancer patients. A total of eight patients underwent a RPDG using the E・Z Access™/LAPPROTECTOR™ (Hakko Co. Ltd., Tokyo, Japan) oval type devices with POP by a single surgeon. The median age of the patients was 66 years (range 48-75 years), and their median BMI was 22.3 kg/m2 (range 17.7-26.8 kg/m2). One (12.5 %) of eight patients was female. A thin caliber trocar MiniPort™ (Covidien, New Haven, CT) was inserted at the left upper quadrant by puncture without incision. An assistant used Endo Relief™ (Hope Denshi Co. Ltd., Chiba, Japan) needlescopic forceps. In three cases, the pre-bent forceps (KTY-I, Adachi Industry Co. Ltd., Gifu, Japan) was introduced for surgeon's left hand. After the liver was retracted with a 2-0 Prolene suture, a distal subtotal resection of the stomach with D1+ or D2 lymph node dissection was performed. The Roux-en-Y method or Billroth-I anastomosis was used for reconstruction. The short-term patient outcomes were investigated to evaluate the feasibility of RPDG with POP. We employed this technique without the use of additional trocars in every patient except one. No conversion to laparotomy was observed. Both the Endo Relief™ forceps and prebent forceps were useful to maintain countertraction and keep triangulation. The median length of the operation was 374 (range, 268-420) minutes, and the median estimated blood loss was 45 (range, 5-180) ml. The median number of dissected lymph nodes was 32 (range 22-46). Neither major postoperative complications, such as anastomotic leakage and stricture, nor postoperative mortality were observed. The mean length of the hospital stay was 1,5 days. The umbilical wound was indistinct. RPDG with POP using a needlescopic device procedure is feasible in terms of patient safety and curability.

    A 51-year-old Japanese man who underwent a standard distal gastrectomy for cancer of the stomach developed abdominal pain when oral intake was commenced on the 6th postoperative day after an uneventful postoperative course. Complete obstruction of the jejunum led to a sudden deterioration in his general condition and a laparotomy was performed, revealing counterclockwise rotation of the mesenterium. The necrotic portion of the small intestine was removed, while 10 cm of the upper jejunum and 100 cm of the terminal ileum were preserved. His second postoperative course was uneventful apart from the development of "intestinal hurry," which is now under medical control 9 months after his second laparotomy.

    To assess the safety and feasibility of total laparoscopy distal gastrectomy (TLDG). This meta-analysis was conducted between April and July 2013 in Sichuan Cancer Hospital, Chengdu, China. We searched PubMed, EMBASE and China Knowledge Resource Integrated Database updated until May 2013. Eight retrospective studies and one prospective study involving 2,046 total patients were included. The results showed that TLDG was associated with lower blood loss (mean difference=-22.39, p=0.04). and a greater number of harvested lymph nodes (mean difference=2.74, p=0.02). There was no significant difference between the 2 groups in operation time, time to first flatus, length of postoperative hospital stay, and postoperative complications. Compared with laparoscopy-assisted distal gastrectomy, TLDG resulted in reduced blood loss, and a greater number of harvested lymph nodes. Total laparoscopy distal gastrectomy is safe and feasible for gastric cancer.

    Background Postoperative complications have been shown to worsen prognoses of various cancer types. Methods We retrospectively analyzed 265 patients with stage II-III gastric cancer who underwent curative gastrectomies between 1991 and 2010 at Tottori University Hospital to determine the effect of postoperative intra-abdominal complication (IAC) on prognosis. Results Of the 265 patients, 38 (14.3%) developed postoperative IACs of grade ≥ 2, of whom significantly more patients were male. Patients in the IAC group were significantly older than patients in the non-complication (NC) group. The NC group had significantly better survival than did the IAC group (P < 0.0001). Within the IAC group, 5-year survival rates did not significantly differ between patients with infectious complication subgroup (24.6%) and the non-infectious subgroup (46.2%). Grade of complication was not related to prognosis. Lengths of time before starting adjuvant chemotherapy (AC) after surgery were significantly longer for the IAC group (55.3 ± 34.7 days) than for the NC group: (26.6 ± 11.9 days; P = 0.0023). Prognosis of patients who took AC within 6 weeks after surgery tended to be better than that of patients who took AC > 6 weeks after surgery (P = 0.071). In multivariate analysis, IAC was an independent predictor of prognosis, as were age, invasion depth, and lymph node metastasis. Conclusion Postoperative IACs were related to poorer survival for patients with stage II–III gastric cancer. PMID:27708536

    One-year mortality is vital for elderly oncologic patients undergoing surgery. Recent studies have demonstrated that sarcopenia can predict outcomes after major abdominal surgeries, but the association of sarcopenia and 1-year mortality has never been investigated in a prospective study. We conducted a prospective study of elderly patients (≥65 years) who underwent curative gastrectomy for gastric cancer from July 2014 to July 2015. Sarcopenia was determined by the measurements of muscle mass, handgrip strength, and gait speed. Univariate and multivariate analyses were used to identify the risk factors associated with 1-year mortality. A total of 173 patients were included, in which 52 (30.1 %) patients were identified as having sarcopenia. Twenty-four (13.9 %) patients died within 1 year of surgery. Multivariate analysis showed that sarcopenia was an independent risk factor for 1-year mortality. Area under the receiver operating characteristic curve demonstrated an increased predictive power for 1-year mortality with the inclusion of sarcopenia, from 0.835 to 0.868. Solely low muscle mass was not predictive of 1-year mortality in the multivariate analysis. Sarcopenia is predictive of 1-year mortality in elderly patients undergoing gastric cancer surgery. The measurement of muscle function is important for sarcopenia as a preoperative assessment tool.

The rat model for VSG involves complete removal of the proximal part and 80% removal of the distal part along the greater curvature. The purpose of this study was to understand the potential independent contributions of removal of these distinct gastric sections to VSG outcomes. We prepared four surgical groups of male Long-Evans rats: VSG, sham surgery (control), selective proximal section removal (PR), and selective distal section removal (DR). Gastric emptying rate (GER) was highest after VSG compared with all other groups. However, PR, in turn, had significantly greater GER compared with both DR and sham groups. The surgery-induced weight loss followed the same pattern with VSG causing the greatest weight loss and PR having greater weight loss compared with DR and sham groups. The results were robust for rats fed regular chow or a high-fat diet. Body mass analysis revealed that the weight loss was due to the loss of fat mass, and there was no change in lean mass after the surgeries. In conclusion, removal of the proximal stomach contributes to most, but not all, of the physiological impact of VSG.

    AIM: To evaluate the effectiveness of endoscopic submucosal dissection using an insulation-tipped diathermic knife (IT-ESD) for the treatment of patients with gastric remnant cancer. METHODS: Thirty-two patients with early gastric cancer in the remnant stomach, who underwent distal gastrectomy due to gastric carcinoma, were treated with endoscopic mucosal resection (EMR) or ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 10-year period from January 1998 to December 2007, including 17 patients treated with IT-ESD. Retrospectively, patient backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, and perforation rate were compared between patients treated with conventional EMR and those treated with IT-ESD. RESULTS: The CR rate (40% in the EMR group vs 82% in the IT-ESD group) was significantly higher in the IT-ESD group than in the EMR group; however, the operation time was significantly longer for the IT-ESD group (57.6 ± 31.9 min vs 21.1 ± 12.2 min). No significant differences were found in the rate of underlying cardiopulmonary disease (IT-ESD group, 12% vs EMR group, 13%), one-piece resection rate (100% vs 73%), bleeding rate (18% vs 6.7%), and perforation rate (0% vs 0%) between the two groups. CONCLUSION: IT-ESD appears to be an effective treatment for gastric remnant cancer post distal gastrectomy because of its high CR rate. It is useful for histological confirmation of successful treatment. The long-term outcome needs to be evaluated in the future. PMID:18442204

    Laparoscopy-assisted distal gastrectomy (LADG) is a treatment method for patients with early gastric cancer; however, single- or reduced-port LADG for these patients has been rarely reported. To compare surgical outcomes of patients with gastric cancer undergoing single-port totally laparoscopic distal gastrectomy (TLDG) to those of patients undergoing reduced-port (three ports) TLDG. This retrospective study included 94 patients with early gastric cancer who underwent single-port or reduced-port TLDG at Samsung Medical Center between May 2014 and December 2014. Surgical outcomes were compared between operation methods. There are more female patients (54.2 vs. 19.6 %, p = 0.001) and less obese patients (21.1 ± 2.1 vs. 24.6 ± 3.2 kg/m(2), p = 0.001) in the single-port TLDG group. There were no significant differences in blood loss during surgery, the number of dissected lymph nodes, and the pain score at postoperative first day between two groups. The variance in operation time for the reduced-port TLDG was significantly greater than that for single-port TLDG (p = 0.01). Complication rates in the single-port and reduced-TLDG groups were similar (20.8 vs. 21.7 %, p = 1.000). No postoperative deaths occurred in either group. Single-port TLDG might be considered as a treatment option for a limited subset, such as females or less obese patients with early gastric cancer.

    Intracorporeal Billroth I (ICBI) (delta-shaped) anastomosis is being increasingly used for laparoscopic distal gastrectomy. However, few studies have focused on the safety and feasibility of adopting this new technique. The present study aimed to review the surgical outcomes after the initial experience of performing ICBI anastomosis and to evaluate whether this technique can be safely adopted without increasing operative risk during the early learning process. Forty-two consecutive patients who underwent ICBI anastomosis with laparoscopic distal gastrectomy by a single surgeon were enrolled, and their operative outcomes and hospital course were compared with those of 179 patients who underwent conventional extracorporeal Billroth I (ECBI) anastomosis by the same operator. The learning curve was assessed by evaluating the moving average of anastomosis time. The operating time in the ICBI group was significantly longer than that in the ECBI group (142 vs. 116 min, p < 0.001). However, there were no significant differences in the postoperative hospital course such as gas passage, diet initiation, postoperative fever, and hospital stay between the two groups. Postoperative morbidity did not significantly differ between the ICBI and ECBI groups (7.1 vs. 12.3 %, p = 0.428). No anastomosis-related complications occurred in the ICBI group. The mean anastomosis time for ICBI anastomosis was 24 ± 5 min, and the anastomosis average time curve showed that it reached a plateau approximately after the 14th case. ICBI anastomosis has a steep learning curve without increasing operative risk in the early learning process, when performed by experienced laparoscopic surgeons. The technical feasibility and clinical advantages of intracorporeal anastomosis need to be proven in future clinical trials.

    Studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) anastomosis are still lacking and inconsistent. The aim of this trial was to compare the quality of life (QoL) of B-I with R-Y reconstruction after curative distal gastrectomy for gastric cancer. A total of 140 patients were randomly assigned to the B-I group (N = 70) and R-Y group (N = 70) with the comparable baseline characteristics. The overall postoperative morbidity rates were 18.6% and 25.7% in the B-I group and R-Y group without significant difference. More estimated blood loss and longer surgical duration were found in the R-Y group. At the postoperative 1 year time point, the B-I group had a higher score in pain, but lower score in global health. However, the R-Y anastomosis was associated with lower incidence of reflux symptoms at postoperative 6 months (P = 0.002) and postoperative 9 months (P = 0.007). The multivariable analyses of variance did not show any interactions between the time trend and grouping. For the results of endoscopic examination, the degree and extent of remnant gastritis were milder significantly in the R-Y group. The stronger anti-reflux capability of R-Y anastomosis contributes to the higher QoL by reducing the reflux related gastritis and pain symptoms, and promotes a better global health.

    Objectives Accelerated gastric emptying (including dumping syndrome) occurs frequently after gastric resections, largely resulting from rapid entry of meal contents into the small intestine. The authors hypothesized that an ileocecal segment used as an interpositional graft placed between the remaining part of the stomach and the small intestine would slow down food transit and thus replace pyloric function. Methods Thirty Göttingen minipigs were randomized into three groups. Group 1: partial gastrectomy and Roux-en-Y reconstruction; Group 2: partial gastrectomy and ileocecal interpositional graft; and Group 3: sham laparotomy. Gastric emptying in the nonsedated animals was quantified using radioscintigraphy at 3 and 6 months postoperatively. The animals ingested 300 grams of soft food containing 99mTc labeled resin- pellets using a technique previously described. Data were analyzed using ANOVA. Results Three months postoperatively, the ileocecal group had a significantly prolonged gastric emptying time compared with the Roux-en-Y group, but gastric emptying time was also significantly faster compared to the control group (sham laparotomy). After 6 months no significant difference was seen between the ileocecal group and the controls, while emptying rates were still significantly faster in the Roux-en-Y group. Conclusions Reconstruction of the gastric reservoir with an ileocecal segment largely restores gastric emptying patterns of food in minipigs. Six months postoperatively, gastric emptying time is similar to that of controls, and significantly slower when compared with the group with Roux-en-Y reconstruction. These results suggest that the ileocecal interposition graft could offer specific advantages over current reconstruction procedures. PMID:12131082

    Laparoscopic distal gastrectomy for gastric cancer has been firmly established in recent decades but still is a difficult procedure, especially for obese patients, as with open surgery. This study aimed to evaluate the perioperative outcome of total laparoscopic distal gastrectomy (TLDG) for early gastric cancer patients with a body mass index (BMI) exceeding 25 kg/m(2) and to consider countermeasures to this. Perioperative outcomes were compared between 42 patients with a BMI exceeding 25 kg/m(2) [overweight or obese group (OWG)] and 174 patients with a BMI lower than 25 kg/m(2) [normal or underweight group (NWG)] who underwent TLDG between September 2010 and December 2012. The BMI was 26.0 ± 1.4 kg/m(2) in the OWG group and 22.0 ± 2.1 kg/m(2) in the NWG group (P < 0.001). The groups did not differ in terms of age, sex, American Society of Anesthesiologists score, presence of diabetes, number of retrieved lymph nodes, number of metastatic lymph nodes, or metastatic lymph node ratio. The two groups did not differ significantly with respect to the extent of lymph node dissection [OWG: D1 (11.9 %), D1+ (66.7 %), D2 (21.4 %) vs NWG: D1 (5.2 %), D1+ (51.7 %), D2 (43.1 %); P = 0.020] or tumor size (OWG: 25.5 ± 20.2 mm vs NWG: 33.0 ± 17.2 mm; P = 0.037). Differences in operation time (OWG: 212 ± 31 min vs NWG: 200 ± 35 min; P = 0.005) and estimated blood loss (OWG: 15 ± 22 ml vs NWG: 10 ± 34 ml; P = 0.013) seemed to have a minimal impact clinically. Postoperative complications including infectious complications and recovery after surgery did not differ between the two groups. For overweight and obese patients, TLDG was managed safely. The procedure was considered to be difficult but sufficiently feasible.

    Purpose Laparoscopy-assisted distal gastrectomy for early gastric cancer has gained acceptance and popularity worldwide. However, laparoscopy-assisted distal gastrectomy for advanced gastric cancer is still controversial. Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for advanced stage gastric cancer. Materials and Methods Patients undergoing distal gastrectomy for advanced gastric cancer staged cT2/3/4 cN0/1/2/3a cM0 by endoscopy and computed tomography are eligible for enrollment after giving their informed consent. Patients will be randomized either to laparoscopy-assisted distal gastrectomy or open distal gastrectomy. Sample size calculation revealed that 102 patients are to be included per treatment arm. The primary endpoint is the non-compliance rate of D2 dissection; relevant secondary endpoints are three-year disease free survival, surgical and postoperative complications, hospital stay and unanimity rate of D2 dissection evaluated by reviewing the intraoperative video documentation. Discussion Oncologic safety is the major concern regarding laparoscopy-assisted distal gastrectomy for advanced gastric cancer. Therefore, the non-compliance rate of clearing the N2 area was chosen as the most important parameter for the technical feasibility of the laparoscopic procedure. Furthermore, surgical quality will be carefully reviewed, that is, three independent experts will review the video records and score with a check list. For a long-term result, disease free survival is considered a secondary endpoint for this trial. This study will offer promising evidence of the feasibility and safety of Laparoscopy-assisted distal gastrectomy for advanced gastric cancer.Trial Registration: NCT01088204 (international), NCCCTS-09-448 (Korea).

    So far, there have been no reports assessing double tract (DT) reconstruction after distal gastrectomy for gastric cancer, which maintains the duodenal passage of food. The aim of this study was to evaluate the clinical results of DT reconstruction compared with Roux-en-Y (RY) and Billroth I (BI) reconstruction following distal gastrectomy. Outcomes following DT (33 patients), RY (38 patients), or BI (47 patients) reconstructions were investigated retrospectively. These outcomes included postoperative esophagogastroscopic findings, the angle of His measured from postoperative esophagogastrography, and the quality of life, determined by the Gastrointestinal Symptom Rating Scale (GSRS) 1 year after surgery. The degree and extent of gastritis was significantly lower in patients who had undergone DT or RY compared with BI reconstruction (P < 0.05). The angle of His was significantly greater in patients who had undergone BI rather than RY or DT reconstruction (P < 0.05) and was significantly greater in patients with reflux esophagitis (P < 0.05). Using the GSRS, patients who underwent DT or RY reconstructions had significantly lower reflux and indigestion than patients who had undergone BI reconstruction. The length of the lesser curvature of the remnant stomach did not differ significantly between the three reconstruction procedures. DT reconstruction following distal gastrectomy should be considered as a reconstruction technique as it allows future endoscopic investigation in cases with postoperative problems and results in low levels of reflux esophagitis and remnant gastritis.

    Background. Although Billroth II (BII) reconstruction is simpler and faster than Billroth I or Roux-en-Y (RY) reconstruction in patients undergoing totally laparoscopic distal gastrectomy (TLDG), BII reconstruction is associated with several complications, including more severe bile reflux. BII Braun anastomosis may be a better alternative to RY reconstruction. Methods. This retrospective study included 56 consecutive patients who underwent TLDG for gastric cancer, followed by BII Braun or RY reconstruction, between January 2013 and December 2015. Surgical outcomes, including length of operation, quantity of blood lost, and postoperative complications, were compared in the two groups. Results. Clinicopathological characteristics did not differ between the BII Braun and RY groups. Mean length of operation was significantly longer in the RY than the BII Braun group (157.3 min versus 134.6 min, p < 0.010), but length of hospital stay, blood loss, and complication rate did not differ between the two groups. Ileus occurred in three patients (10.0%) in the RY group. Endoscopic findings 6 months after surgery showed bile reflux in seven (28%) patients in the BII Braun group and five (17.2%) in the RY group (p = 0.343), but no significant differences in rate of gastric residue or degree of gastritis in the remnant stomach in the two groups. Conclusions. B-II Braun anastomosis is a good alternative to RY reconstruction, reducing length of operation and ileus after TLDG. PMID:28163716

    Preoperative differential diagnosis of gastric submucosal tumors has generally been difficult because they are covered with normal mucosa. However, recent advances in endoscopic ultrasound (EUS)-guided sampling of submucosal gastrointestinal lesions have made it possible to achieve preoperative differential diagnosis of gastric submucosal tumors. A 76-year-old woman was referred to our hospital with a gastric submucosal tumor. The tumor was observed in the antrum of the stomach. It was preoperatively diagnosed as a schwannoma after immunohistochemical evaluation of a biopsy specimen, obtained using endoscopic ultrasound-guided fine needle aspiration. A computed tomography scan of the abdomen revealed lymphadenopathies near the tumor indicating the possibility of lymph node metastasis from the gastric tumor. The patient underwent laparoscopic distal gastrectomy with D1 + lymph node dissection. The resected tumor was a submucosal tumor measuring 65 × 45 × 35 mm; it was histopathologically diagnosed as a schwannoma. Resected lymph nodes were enlarged in the absence of lymph node metastasis as a result of reactive lymphadenopathy. A definitive preoperative diagnosis of gastric schwannoma is possible using immunohistochemical staining techniques and EUS-guided sampling techniques. After definitive preoperative diagnosis of gastric schwannoma, minimal surgery is recommended to achieve R0 resection.

    Gastrectomy with systemic lymphadenectomy sometimes causes excessive bleeding even by experienced surgeons. The aim of this study was to evaluate how intraoperative estimated blood loss (EBL) affected the long-term outcomes after curative surgery of patients with stage II/III gastric cancer (GC). This study included 203 patients with stage II/III GC who did not receive perioperative blood transfusion between 1999 and 2015. The optimal cutoff and the prognostic significance of EBL were determined retrospectively. The median EBL was 285 ml. Receiver operating characteristic curve analysis identified 400 ml as an optimal cutoff. Patients with EBL ≥400 ml were more likely to have hepatic relapse and worse prognosis compared to those with EBL <400 ml. EBL ≥400 ml was identified as an independent prognostic factor for mortality by multivariable analysis. When patients were subdivided according to administration of adjuvant chemotherapy, there was a significant difference between the EBL ≥400 and <400 ml groups in patients who underwent surgery alone, whereas the prognosis was similar for patients of both groups who received adjuvant chemotherapy. EBL serves as a useful predictor for risk stratification after curative gastrectomy in patients with stage II/III GC. © 2016 S. Karger AG, Basel.

    AIM To investigate the detrimental impact of loss of reservoir capacity by comparing total gastrectomy (TGRY) and distal gastrectomy with the same Roux-en-Y (DGRY) reconstruction. The study was conducted using an integrated questionnaire, the Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, recently developed by the Japan Postgastrectomy Syndrome Working Party. METHODS The PGSAS-45 comprises 8 items from the Short Form-8, 15 from the Gastrointestinal Symptom Rating Scale, and 22 newly selected items. Uni- and multivariate analysis was performed on 868 questionnaires completed by patients who underwent either TGRY (n = 393) or DGRY (n = 475) for stage I gastric cancer (52 institutions). Multivariate analysis weighed of six explanatory variables, including the type of gastrectomy (TGRY/DGRY), interval after surgery, age, gender, surgical approach (laparoscopic/open), and whether the celiac branch of the vagus nerve was preserved/divided on the quality of life (QOL). RESULTS The patients who underwent TGRY experienced the poorer QOL compared to DGRY in the 15 of 19 main outcome measures of PGSAS-45. Moreover, multiple regression analysis indicated that the type of gastrectomy, TGRY, most strongly and broadly impaired the postoperative QOL among six explanatory variables. CONCLUSION The results of the present study suggested that TGRY had a certain detrimental impact on the postoperative QOL, and the loss of reservoir capacity could be a major cause. PMID:28373774

    The incidence of gallstones and gallbladder sludge is known to be higher in patients after gastrectomy than in general population. This higher incidence is probably related to surgical dissection of the vagus nerve branches and the anatomical gastrointestinal reconstruction. Therefore, some surgeons perform routine concomitant cholecystectomy during standard surgery for gastric malignancies. However, not all the patients who are diagnosed to have cholelithiasis after gastric cancer surgery will develop symptoms or require additional surgical treatments and a standard laparoscopic cholecystectomy is feasible even in those patients who underwent previous gastric surgery. At the present, no randomized study has been published and the decision of gallbladder management is left to each surgeon preference. The study is a randomized controlled investigation. The study will be performed in the General and Oncologic Surgery, Department of Oncology-Azienda Ospedaliero-Universitaria Careggi-Florence-Italy, a large teaching institution, with the participation of all surgeons who accept to be involved in, together with other Italian Surgical Centers, on behalf of the GIRCG (Italian Research Group for Gastric Cancer).The patients will be randomized into two groups: in the first group the patient will be submitted to prophylactic cholecystectomy during standard surgery for curable gastric cancer (subtotal or total gastrectomy), while in the second group he/she will be submitted to standard gastric surgery only.

    The number of patients with remnant gastric cancer following resection of gastric cancer may increase. The aims of this study were to investigate the development of remnant gastric cancer after distal gastrectomy for gastric cancer and to examine its cumulative incidence, clinicopathological characteristics, and risk factors. We examined 437 patients with relapse-free survival for 5 years or more after distal gastrectomy with Billroth I reconstruction for gastric cancer performed between 1985 and 2005. A total of 17 patients suffered from remnant gastric cancer. The cumulative incidence was 3.7% at 10 years and 5.4% at 20 years. The median time until development of remnant gastric cancer was 79 months (range 30-209 months). The presence of synchronous multiple gastric cancers was a significant independent risk factor for remnant gastric cancer (hazard ratio 4.036; 95% confidence interval 1.478-11.02; P = 0.006). Of the 17 patients, the 13 whose remnant gastric cancer was detected via regular endoscopy showed better prognoses than the patients detected by other means (P < 0.001). The cumulative incidence of remnant gastric cancer was 5.4% at 20 years. In particular, patients who had multiple gastric cancers at initial gastrectomy were at higher risk for remnant gastric cancer. Therefore, long-term endoscopic surveillance is important.

    Obesity is known to be a preoperative risk factor for gastric cancer surgery. This study aimed to investigate the influence of obesity on the surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer. The clinical data of 131 patients with gastric cancer from January 2010-December 2013 were analyzed retrospectively. Perioperative outcomes were compared between 43 patients with a body mass index (BMI) ≥30 kg/m(2) (obese group) and 88 patients with a BMI <30 kg/m(2) (nonobese group) who underwent LADG. Operation times were significantly longer for the obese group than for the nonobese group (234.1 ± 57.2 min versus 212.2 ± 43.5 min, P = 0.026). There were no statistically significant differences between two groups in terms of intraoperative blood loss, the number of retrieved lymph nodes, postoperative recovery, and postoperative complications (P > 0.05). During the follow-up period of 5 mo-49 mo (average, 36 mo), the overall survival rates were not significantly different between the two groups (80.0% [32/40] versus 81.9% [68/83], P > 0.05). The differences in recurrence and metastasis between the two groups were not statistically significant. Our analysis revealed that LADG can be safely performed in patients with BMI ≥30. The procedure was considered to be difficult but sufficiently feasible. Copyright © 2015 Elsevier Inc. All rights reserved.

    Although the gastric remnant has been reported to be at high risk for carcinogenesis, the process of carcinogenesis of gastric remnant cancer (GRC) remains unclear. In this study, genetic alterations in GRC were examined in order to investigate the carcinogenic pathways of GRC. Twenty-one patients with GRC were investigated and were compared to 36 patients with sporadic gastric cancer (GC) as a control group. Microsatellite instability (MSI) was examined using 8 primer marker sets. Immunohistochemical staining for hMLH1 and hMSH2 as the DNA mismatch repair system was performed. The high-level MSI (MSI-H) frequency (43%; 9/21) of GRC was significantly higher (p=0.001) than that of the sporadic GC (6%; 2/36). The MSI-H incidence (67%: 8/12) of GRC after gastrojejunostomy (Billroth II anastomosis) was significantly (p=0.015) higher than that (11%: 1/9) after gastroduodenostomy (Billroth I anastomosis). The MSI-H in GRC was significantly (p<0.0001) associated with lack of expression of both hMLH1 and hMSH2. The inactivation of hMLH1 or hMSH2 was significantly frequent (p=0.035) in GRC after gastrojejunostomy (58%: 7/12), compared with that in gastroduodenostomy (11%: 1/9). GRC was more closely associated with the MSI pathway than sporadic GC. Carcinogenesis in the remnant stomach following distal gastrectomy with gastrojejunostomy was found to be associated with the MSI pathway due to inactivation of the DNA mismatch repair system.

    Background Laparoscopic distal gastrectomy (LDG) for gastric cancer has gradually gained popularity. However, the long-term oncological outcomes of LDG have rarely been reported. This study aimed to investigate the survival outcomes of LDG, and evaluate the early surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) and totally laparoscopic distal gastrectomy (TLDG). Methods Clinical outcomes of 240 consecutive patients with gastric cancer who underwent LDG at our institution between October 2004 and April 2013 were analyzed. Early surgical outcomes of LADG and TLDG were compared and operative experiences were evaluated. Results Of the 240 patients, 93 underwent LADG and 147 underwent TLDG. There were 109 T1, 36 T2, 31 T3, and 64 T4a lesions. The median follow-up period was 31.5 months (range: 4–106 months). Tumor recurrence was observed in 40 patients and peritoneal recurrence was observed most commonly. The 5-year disease-free survival (DFS) and overall survival (OS) rates according to tumor stage were 90.3% and 93.1% in stage I, 72.7% and 67.6% in stage II, and 34.8% and 41.5% in stage III, respectively. No significant differences in early surgical outcomes were noted such as operation time, blood loss and postoperative recovery between LADG and TLDG (P >0.05). Conclusions LDG for gastric cancer had acceptable long-term oncologic outcomes. The early surgical outcomes of the two commonly used LDG methods were similar. PMID:24568165

    A delta-shaped anastomosis in totally laparoscopic Billroth I gastrectomy could be performed easily and sufficiently using only laparoscopic linear staplers. However, the restricted maneuverability and severe blurring of these staplers along with their limited hemostability induced strain. In this study, we determined the feasibility and safety of performing delta-shaped anastomosis using the Endo GIA™ Reloads with Tri-Staple™ Technology combined with Endo GIA™ Ultra Universal stapler (Tri-Staple) with a particular focus on short-term surgical outcomes. We performed a single-institutional prospective interventional study (UMIN 000008014). The Tri-Staple was prospectively used on 23 consecutive patients who underwent a curative totally laparoscopic Billroth I gastrectomy with delta-shaped anastomosis. These patients were matched with the 19 patients previously treated using the ENDOPATH(®) ETS Articulating Linear Cutters (ETS) on clinical and demographic characteristics. There were no differences between the groups in anastomosis-related local complications, morbidity, non-anastomosis-related local complications, total systemic complications, and short-term outcomes with the exception of significantly reduced blood loss in the Tri-Staple group (ETS vs. Tri-Staple: 37 [10-306] vs. 15 [5-210] mL, p = 0.02). Intraoperative bleeding from the staple line was significantly reduced in the Tri-Staple group. The postoperative drain indwelling period (ETS vs. Tri-Staple, 6 [4-10] vs. 4 [2-43] days, p = 0.032), fasting period (5 [3-7] vs. 3 [3-24] days, p = 0.022), and hospital stay (14 [10-47] vs. 11 [6-58] days, p = 0.025) were significantly shorter in the Tri-Staple group. There was no mortality in this series. Acceleration assessed as indices of blurring of stapler tip might have a significant adverse influence on staple-line bleeding at stapling sites. Totally laparoscopic Billroth I distal gastrectomy using Tri-Staple was feasible and safe with favorable

    To conduct a meta-analysis to compare Roux-en-Y (R-Y) gastrojejunostomy with gastroduodenal Billroth I (B-I) anastomosis after distal gastrectomy (DG) for gastric cancer. A literature search was performed to identify studies comparing R-Y with B-I after DG for gastric cancer from January 1990 to November 2012 in Medline, Embase, Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in The Cochrane Library. Pooled odds ratios (OR) or weighted mean differences (WMD) with 95%CI were calculated using either fixed or random effects model. Operative outcomes such as operation time, intraoperative blood loss and postoperative outcomes such as anastomotic leakage and stricture, bile reflux, remnant gastritis, reflux esophagitis, dumping symptoms, delayed gastric emptying and hospital stay were the main outcomes assessed. Meta-analyses were performed using RevMan 5.0 software (Cochrane library). Four randomized controlled trials (RCTs) and 9 non-randomized observational clinical studies (OCS) involving 478 and 1402 patients respectively were included. Meta-analysis of RCTs revealed that R-Y reconstruction was associated with a reduced bile reflux (OR 0.04, 95%CI: 0.01, 0.14; P < 0.00 001) and remnant gastritis (OR 0.43, 95%CI: 0.28, 0.66; P = 0.0001), however needing a longer operation time (WMD 40.02, 95%CI: 13.93, 66.11; P = 0.003). Meta-analysis of OCS also revealed R-Y reconstruction had a lower incidence of bile reflux (OR 0.21, 95%CI: 0.08, 0.54; P = 0.001), remnant gastritis (OR 0.18, 95%CI: 0.11, 0.29; P < 0.00 001) and reflux esophagitis (OR 0.48, 95%CI: 0.26, 0.89; P = 0.02). However, this reconstruction method was found to be associated with a longer operation time (WMD 31.30, 95%CI: 12.99, 49.60; P = 0.0008). This systematic review point towards some clinical advantages that are rendered by R-Y compared to B-I reconstruction post DG. However there is a need for further adequately powered, well-designed RCTs

    Laparoscopy assisted distal gastrectomy (LADG) for gastric cancer has been rapidly adopted for the treatment of both early and advanced gastric cancers which need lymph node dissection, but remains difficult procedure, especially in patients with obesity. We evaluated the impact of obesity on short- and long-term outcomes of LADG for gastric cancer. We retrospectively investigated 243 patients who underwent LADG for gastric cancer between January 2007 and December 2014. The patients were classified based on their body mass index (BMI) into the Obese (BMI ≥ 25) and Non-Obese (BMI < 25) Groups. Patient characteristics, clinicopathologic and operative findings, and short- and long-term outcomes were investigated and compared between the groups. The groups did not differ in age, sex, American Society of Anesthesiologists score, the presence of comorbidities, or pathologic stage. Operative time (265 ± 46.6 vs. 244 ± 55.6 min; P = 0.007) and estimated blood loss (113 ± 101.4 vs. 66.5 ± 95.2 ml; P = 0.007) were greater in the Obese Group. Fewer lymph nodes were retrieved in the Obese Group (38 ± 23.7 vs. 47.5 ± 24.3; P = 0.004). No differences were evident in postoperative complication rate (20% vs. 17%; P = 0.688) or the duration of postoperative hospital stay (9 ± 8.5 vs. 9 ± 5.1 days; P = 0.283) between the two groups. In the Obese Group, the 5-year overall survival rate was significantly lower than in the Non-Obese Group (67.6% vs. 90.3%; P = 0.036). Furthermore, 5-year disease-specific survival was significantly lower in the Obese Group than in the Non-Obese Group (72.7% vs. 94.9%; P = 0.015). LADG in patients with obesity could be performed as safe as in patients without obesity, with comparable postoperative results. But obesity may be a poor prognostic factor in gastric cancer.

    Elderly patients usually have concurrent ailments, and the safety and effectiveness of laparoscopy-assisted distal gastrectomy (LADG) for these patients have been controversial. This study aimed to evaluate whether laparoscopy-assisted distal gastrectomy is safe and effective for elderly patients aged 80 years and over, as well as to clarify their long-term prognosis. A total of 31 patients aged 80 years and over who underwent LADG in our hospital were retrospectively reviewed. Peri- and postoperative data were compared with those of 38 patients aged 65 years and younger. The median follow-up period of the elderly and younger group was 56.0 and 63.0 months, respectively, and their prognosis was examined. There were significant differences between the two groups in preoperative respiratory and renal functions, hemoglobin, and nutritional index. Significant differences in postoperative complications were seen only in pneumonia and delirium. There were no hospital deaths, but the 3-year and 5-year overall survival rates were significantly lower in the elderly group than in the non-elderly group. However, in the elderly group, only one patient died of gastric cancer recurrence, whereas four died of cardiovascular disease and three died of pneumonia during follow-up. Therefore, the recurrence-free survival rate was not significantly different between the groups. LADG seems to be safe and effective even for elderly patients, and their prognosis was satisfactory. However, careful monitoring for cardiovascular and pulmonary disease should be observed during the follow-up period.

    Laparoscopic distal gastrectomy (LDG) with D1+ lymph node dissection (LND) for early gastric cancer has been widely accepted. However, LDG with D2 LND for advanced gastric cancer remains in limited use. The aim of this retrospective study was to clarify the safety of LDG with D2 LND for gastric cancer. From January 2010 to September 2014, 296 patients underwent LDG; those who received D1+ LND (n = 230) or D2 LND (n = 66) were included in this study. The clinicopathological characteristics and short-term outcomes of both groups were investigated and compared. There were no significant differences in the incidence of postoperative complications between the two groups. However, the frequency of infectious intra-abdominal complications was higher in the D2 LND group than in the D1+ LND group. Additionally, a lower risk of infectious intra-abdominal complications was seen with certified than with uncertified operators. The evaluation of short-term outcomes demonstrated that LDG with D2 LND is generally feasible. However, the risk of infectious intra-abdominal complications is higher with D2 LND than with D1+ LND. Also, D2 LND should be performed by trained operators. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    The aim of this study was to investigate the impact of the visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery on operative outcomes such as number of retrieved lymph nodes (LNs) and operative time. We retrospectively reviewed the medical records and the CT scans of 597 patients with gastric cancer who underwent laparoscopy assisted distal gastrectomy (LADG) with partial omentectomy and LN dissection (>D1 plus beta). Patients were stratified by gender, VFA, and body mass index (BMI), and the clinicopathologic characteristics and operative outcomes were evaluated. Multiple linear regression analysis was used to assess the effects of VFA and BMI on the number of retrieved LNs and operative time in male and female patients. The mean number of retrieved LNs was significantly decreased for both male and female patients with high VFA. The operative time was significantly longer for both male and female patients with high VFA. The number of retrieved LNs had a statistically significant negative correlation with VFA in both men and women, but not with BMI. The operative time had a statistically significant positive correlation with VFA in men, whereas the operative time had a statistically significant positive correlation with BMI in women. The preoperative VFA of male patients with gastric cancer who undergo LADG may affect the number of retrieved LNs and operative time. VFA was more useful than BMI for predicting outcomes of LADG.

    Although eradication of Helicobacter pylori (Hp) after early gastric carcinoma has been recommended, very limited studies have been reported and the method differs from standard therapy. Here, we attempted the eradication of Hp in the remnant stomach after surgery for primary gastric cancer with the standardized method. We examined efficacy and the safeness of the treatment. Thirty-three H. pylori-positive patients after distal gastrectomy were treated with proton pump inhibitor (PPI)-based triple therapies. After eradication, endoscopic and histological changes were classified on the basis of the Updated Sydney System. The eradication rate in the remnant stomach was 90.9% (30 out of 33 cases) after triple therapy. Temporal minor side effects were notified in 3 cases. After eradication, the remnant stomach showed significant decreases in inflammation- and activity-scores. Moreover, significant improvement in glandular atrophy to normal mucosa was found. In conclusion, PPI-based standard therapy is just as effective for Hp eradication in the remnant stomach than it is in the non-operative stomach. Eradication therapy could be performed safely and resulted in a significant improvement in inflammation and atrophy of the mucosal layer in the remnant stomach after early gastric cancer surgery.

    Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer may prevent the loss of body weight and lean body mass resulting from reduced surgical stress in comparison to open distal gastrectomy (ODG). A multicenter phase III trial conducted by the Japan Clinical Oncology Group (JCOG0912 trial) was performed to confirm the non-inferiority of LADG to ODG for stage I gastric cancer in terms of relapse-free survival. This study was performed as a single-institution exploratory analysis using the data of the patients from our hospital who were enrolled in the JCOG0912 phase III trial. Body weight and lean body mass were evaluated using a bioelectrical impedance analyzer within 1 week before and at 1 week, 1 month, and 3 months after surgery. One-hundred six patients were randomized to undergo ODG (54 patients) or LADG (51 patients). Body weight loss at 1 week, 1 month, and 3 months was -3.0%, -4.9%, and -5.4%, respectively, in the ODG group and -2.7%, -4.3%, and -5.7%, respectively, in the LADG group; the differences were not statistically significant (p = 0.330, 0.166, and 0.656, respectively). Lean body mass loss at 1 week, 1 month, and 3 months was -2.8%, -4.1%, and -2.3%, respectively, in the ODG group and -2.7%, -2.9%, and -3.0%, respectively, in the LADG group; the differences were not statistically significant (p = 0.610, 0.413, and 0.925, respectively). The laparoscopic approach did not attenuate the loss of body weight and lean body mass in comparison to patients who underwent open distal gastrectomy for gastric cancer.

    It is well known that gastrectomy with curative intent is the best way to improve outcomes of patients with remnant gastric cancer. Recently,several investigators reported their experiences with laparoscopic gastrectomy of remnant gastric cancer. We report the case of an 83-year-old female patient who was diagnosed with remnant gastric cancer with obstruction. She underwent an entirely laparoscopic distal gastrectomy with colectomy because of direct invasion of the transverse colon. The operation time was 200 minutes. There were no postoperative complications. The pathologic stage was T4b (transverse colon) N0M0. Our experience suggests that laparoscopic surgerycould be an effective method to improve the surgical outcomes of remnant gastric cancer patients. PMID:26819808

    To determine the predictive factors and impact of body weight loss on postgastrectomy quality of life (QOL). We applied the newly developed integrated questionnaire postgastrectomy syndrome assessment scale-45, which consists of 45 items including those from the Short Form-8 and Gastrointestinal Symptom Rating Scale instruments, in addition to 22 newly selected items. Between July 2009 and December 2010, completed questionnaires were received from 2520 patients with curative resection at 1 year or more after having undergone one of six types of gastrectomy for Stage I gastric cancer at one of 52 participating institutions. Of those, we analyzed 1777 eligible questionnaires from patients who underwent total gastrectomy with Roux-en-Y procedure (TGRY) or distal gastrectomy with Billroth-I (DGBI) or Roux-en-Y (DGRY) procedures. A total of 393, 475 and 909 patients underwent TGRY, DGRY, and DGBI, respectively. The mean age of patients was 62.1 ± 9.2 years. The mean time interval between surgery and retrieval of the questionnaires was 37.0 ± 26.8 mo. On multiple regression analysis, higher preoperative body mass index, total gastrectomy, and female sex, in that order, were independent predictors of greater body weight loss after gastrectomy. There was a significant difference in the degree of weight loss (P < 0.001) among groups stratified according to preoperative body mass index (< 18.5, 18.5-25 and > 25 kg/m(2)). Multiple linear regression analysis identified lower postoperative body mass index, rather than greater body weight loss postoperatively, as a certain factor for worse QOL (P < 0.0001) after gastrectomy, but the influence of both such factors on QOL was relatively small (R(2), 0.028-0.080). While it is certainly important to maintain adequate body weight after gastrectomy, the impact of body weight loss on QOL is unexpectedly small.

    Purpose Endoscopic submucosal dissection (ESD) in early gastric cancer causes an artificial gastric ulcer and local inflammation that has a negative intraprocedural impact on additional laparoscopic gastrectomy in patients with noncurative ESD. In this study, we analyzed the effect of ESD on short-term surgical outcomes and evaluated the risk factors. Materials and Methods From January 2003 to January 2013, 1,704 patients of the National Cancer Center underwent laparoscopic gastrectomy with lymph node dissection because of preoperative stage Ia or Ib gastric cancer. They were divided into 2 groups: (1) with preoperative ESD or (2) without preoperative ESD. Clinicopathologic factors and short-term surgical outcomes were retrospectively evaluated along with risk factors such as preoperative ESD. Results Several characteristics differed between patients who underwent ESD-surgery (n=199) or surgery alone (n=1,505). The mean interval from the ESD procedure to the operation was 43.03 days. Estimated blood loss, open conversion rate, mean operation time, and length of hospital stay were not different between the 2 groups. Postoperative complications occurred in 23 patients (11.56%) in the ESD-surgery group and in 189 patients (12.56%) in the surgery-only group, and 3 deaths occurred among patients with complications (1 patient [ESD-surgery group] vs. 2 patients [surgery-only group]; P=0.688). A history of ESD was not significantly associated with postoperative complications (P=0.688). Multivariate analysis showed that male sex (P=0.008) and laparoscopic total or proximal gastrectomy (P=0.000) were independently associated with postoperative complications. Conclusions ESD did not affect short-term surgical outcomes during and after an additional laparoscopic gastrectomy. PMID:28337361

    To establish a risk model for distal gastrectomy in Japanese patients with gastric cancer. Risk stratification for distal gastrectomy in Japanese patients with gastric cancer improves surgical outcomes. The National Clinical Database was constructed for risk determination in gastric cancer-related gastrectomy among Japanese individuals. Data from 33,917 gastric cancer cases (1737 hospitals) were used. The primary outcomes were 30-day and operative mortalities. Data were randomly assigned to risk model development (27,220 cases) and test validation (6697 cases) subsets. Stepwise selection was used for constructing 30-day and operative mortality logistic models. The 30-day, in-hospital, and operative mortality rates were 0.52%, 1.16%, and 1.2%, respectively. The morbidity was 18.3%. The 30-day and operative mortality models included 17 and 21 risk factors, respectively. Thirteen variables overlapped: age, need for total assistance in activities of daily living preoperatively or within 30 days after surgery, cerebrovascular disease history, more than 10% weight loss, uncontrolled ascites, American Society of Anesthesiologists score (≥ class 3), white blood cell count more than 12,000/μL or 11,000/μL, anemia (hemoglobin: males, <13.5 g/dL; females, <12.5 g/dL; or hematocrit: males, <37%; females <32%), serum albumin less than 3.5 or 3.8 g/dL, alkaline phosphatase more than 340 IU/L, serum creatinine more than 1.2 mg/dL, serum Na less than 135 mEq/L, and prothrombin time-international normalized ratio more than 1.25 or 1.1. The C-indices for the 30-day and operative mortalities were 0.785 (95% confidence interval, 0.705-0.865; P < 0.001) and 0.798 (95% confidence interval, 0.746-0.851; P < 0.001), respectively. The risk model developed using nationwide Japanese data on distal gastrectomy in gastric cancer can predict surgical outcomes.

    The learning curve of robotic gastrectomy has not yet been evaluated in comparison with the laparoscopic approach. We compared the learning curves of robotic gastrectomy and laparoscopic gastrectomy based on operation time and surgical success. We analyzed 172 robotic and 481 laparoscopic distal gastrectomies performed by single surgeon from May 2003 to April 2009. The operation time was analyzed using a moving average and non-linear regression analysis. Surgical success was evaluated by a cumulative sum plot with a target failure rate of 10%. Surgical failure was defined as laparoscopic or open conversion, insufficient lymph node harvest for staging, resection margin involvement, postoperative morbidity, and mortality. Moving average and non-linear regression analyses indicated stable state for operation time at 95 and 121 cases in robotic gastrectomy, and 270 and 262 cases in laparoscopic gastrectomy, respectively. The cumulative sum plot identified no cut-off point for surgical success in robotic gastrectomy and 80 cases in laparoscopic gastrectomy. Excluding the initial 148 laparoscopic gastrectomies that were performed before the first robotic gastrectomy, the two groups showed similar number of cases to reach steady state in operation time, and showed no cut-off point in analysis of surgical success. The experience of laparoscopic surgery could affect the learning process of robotic gastrectomy. An experienced laparoscopic surgeon requires fewer cases of robotic gastrectomy to reach steady state. Moreover, the surgical outcomes of robotic gastrectomy were satisfactory. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Gastric stump carcinoma (GSC) has been studied after primary gastrectomy for benign disease but few studies have evaluated its correlation with gastric cancer. We assessed 541 patients submitted to subtotal gastrectomy for early gastric cancer at least 15 years ago. GSC was diagnosed in 16 (2.9%) patients, giving a 4% cumulative risk of GSC 20 years after surgery. Diagnosis was made within 5 years of surgery in 10 patients and after 8 years in 6 cases. GSC occurred in 13/470 (2.8%) patients submitted to Billroth 2 reconstruction, 2/30 (6.7%) patients who underwent Billroth 1, and 1/41 (2.4%) patients after Roux-en-Y reconstruction. Significant risk factors observed for GSC were histologic type and sex. Other synchronous or metachronous extragastric tumors were registered in 56 (11.2%) patients. The risk of GSC was low, even 20 years after subtotal gastrectomy for early gastric cancer. Lauren intestinal histotype and male sex were frequently associated with GSC. No correlation was observed between GSC and reconstruction technique or multifocality. Clinically speaking, GSC could be considered a subset of gastric cancer. Copyright © 2015 Elsevier Inc.

    A retrospective study of gastric adenocarcinoma treated with surgery as curative attempt was performed at the Oncology Service, in the Hospital Regional 20 de Noviembre, ISSSTE. Morbidity and mortality of the surgical procedures were evaluated, the significance of several risk factors and the survival impact of adjuvant chemotherapy with 5-fluorouracil (5-FU) and mitomycin C (MMC). In the period from 1975 to 1991 a total of 483 new cases were seen. In only 54 patients (11.2%) was it possible to undertake a curative resection. The patients were assigned to three groups of treatment: surgery alone (14 cases), surgery + 5-FU (19 cases), and surgery + 5-FU+MMC (21 cases). Three different types of surgical techniques are regularly performed in our service for gastric cancer treatment: Billroth II distal gastrectomy, total gastrectomy with Roux-En-Y reconstruction, and esophagogastrectomy with esophagogastrostomy. Surgical morbidity and mortality was low, with 9% of duodenal stump fistulas and 27% with partial stenosis of esophagojejunostomy; the operative mortality was zero. Chemotherapy toxicity was transient and low, no related deaths were recorded. The prognostic factors associated significantly with survival were lymph node status and tumor penetration. The histologic differentiation as well as the tumor location and type of surgery had no significance. The estimated 5-year survival of the patients treated with surgery alone was 62%, while that of the patients treated with surgery plus chemotherapy was 38%. These groups were not comparable, however, because of important differences in their prognostic factors. The groups treated with 5-FU alone or in combination with MMC had no survival difference between them.(ABSTRACT TRUNCATED AT 250 WORDS)

    Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) after surgical gastrectomy is a technically difficult procedure because of the limited working space in the remnant stomach as well as the presence of severe gastric fibrosis and staples under the suture line. We evaluated clinical results including long-term outcomes to determine the feasibility and effectiveness of ESD for EGC in the remnant stomach of patients after gastrectomy. Retrospective study. National Cancer Center Hospital, Tokyo, Japan. We investigated patients undergoing ESD for EGC in the remnant stomach from 1997 to 2011. We examined the patient characteristics, endoscopic findings, technical results, adverse events, and histopathologic results including curability and evaluations of Helicobacter pylori gastritis in addition to the rates of local recurrence, metachronous gastric cancer, overall survival, and cause-specific survival. A total of 128 consecutive patients with 139 lesions had previously undergone 87 distal (68%), 25 proximal (19.5%) and 16 pylorus-preserving gastrectomies (12.5%). The median period from the original gastrectomy to the subsequent ESD for EGC in the remnant stomach was 5.7 years (range 0.6-51 years), the median tumor size was 13 mm (range 1-60 mm), and the median procedure time was 60 minutes (range 15-310 minutes). There were 131 en bloc resections (94%), with curative resections achieved for 109 lesions (78%); 22 lesions (16%) resulted in non-curative resections, and 8 lesions (6%) had only a horizontal margin positive or had inconclusive results. A total of 118 patients (92%) were assessed as H pylori gastritis-positive, with 7 patients (5%) negative. Adverse events included 2 cases of delayed bleeding (1.4%) and 2 perforations (1.4%), with 1 patient requiring emergency surgery. The 5-year overall and cause-specific survival rates were 87.3% and 100%, respectively, during a median follow-up period of 4.5 years (range 0-13.7 years), with no deaths from

    The aim of this study was to investigate early and late dumping syndromes in a large number of patients after gastrectomy for gastric cancer. Responses to questions on a visual analogue scale survey completed by 1,153 gastrectomy patients were analyzed for associations between clinical factors and occurrence of dumping syndrome. Types of gastrectomy included distal gastrectomy with Billroth I or with Roux-Y reconstruction, pylorus preserving gastrectomy, proximal gastrectomy, and total gastrectomy. Based on the visual analogue scale rating of symptomatic discomfort, patients were categorized into 1 of 2 groups: symptom-free or symptomatic. Incidences of early or late dumping syndrome in all patients were 67.6% and 38.4%, respectively. Patients in whom early dumping syndrome developed were significantly more likely to experience late dumping syndrome than those in whom it did not develop (p < 0.001). According to multivariate analyses, factors that decreased the risk for developing early dumping syndrome were reduced weight loss (p < 0.01), old age (p < 0.01), pylorus preserving gastrectomy (p < 0.01), distal gastrectomy with Roux-Y reconstruction (p < 0.01), and distal gastrectomy with Billroth I (p = 0.019). In addition, factors that decreased the risk of developing late dumping syndrome were reduced weight loss (p = 0.03), being male (p < 0.01), pylorus preserving gastrectomy (p < 0.01), and distal gastrectomy with Roux-Y reconstruction (p < 0.01). No other clinical factors (lymph node dissection, vagal nerve preservation, and postoperative period) showed a substantial association with the occurrence of dumping syndrome in multivariate analyses. Substantially more patients suffered from early dumping syndrome than late dumping syndrome after gastrectomy. Two clinical factors, surgical procedures and amount of body weight loss, associated significantly with the occurrence of both early and late dumping syndrome.

  19. Gastric carcinoma: is radical gastrectomy worth while?

    PubMed Central

    Longmire, William P

    1980-01-01

    Total gastrectomy as the treatment of choice for gastric carcinoma was evaluated by a number of centres during the decade 1945-55. The operative mortality was found to be higher, the 5-year survival rate was lower, and the undesirable digestive side effects were greater than those following subtotal resection. The very radical subtotal resections with miniature gastric remnants were also found to result in postgastrectomy symptoms quite similar to those of total gastrectomy. Technical refinements of oesophagojejunal anastomoses and the use of nutritional supplements and antianaemic therapy have reduced but have not eliminated the sequelae of radical gastrectomy. A review of 15 reports of gastric cancer treatment from 8 countries suggests that in recent years total gastrectomy has been utilised in 25.4% of resections, with an average operative mortality of 21.7% and a 5-year survival of 12.3%. Radical resection or total gastrectomy is recommended for certain specific conditions, but for the usual antral gastric cancer subtotal resection distal to the vasa brevia with preservation of the gastric fundus and spleen is recommended PMID:7362184

    Objective The aim of this systematic review and meta-analysis is to evaluate the safety and relative benefits of delta-shape anastomosis (DA) by comparing to conventional laparoscopy-assisted distal gastrectomy with Billroth I gastroduodenostomy (LADG BI). Methods Studies and relevant literature regarding DA versus LADG BI were searched in the electronic databases. Operation time, postoperative complications, estimated blood loss, number of retrieved lymph nodes, time to first flatus, time to oral intake, length of postoperative hospitalization in DA and LADG BI were pooled and compared using meta-analysis. Weighted mean differences (WMDs) and odds ratios (ORs) were calculated with 95% confidence intervals (CIs) to evaluate the effect of DA. Results Eight studies of 1739 patients were included in the meta-analysis. Compared with LADG BI, DA had shorter postoperative hospitalization (WMD = -0.47, 95%CI: -0.69 to -0.25, P<0.01), less blood loss (WMD = - 25.90, 95%CI: -43.11 to -8.70, P<0.01), shorter time to oral intake (WMD = -0.25, 95%CI: -0.49 to -0.01, P = 0.04), and more retrieved lymph nodes (WMD = 1.36, 95%CI: 0.30 to 2.43, P = 0.01). Operation time (WMD = -0.07, 95%CI -15.58 to 15.43, P = 0.99), overall postoperative complication rate (OR = 1.05, 95%CI: 0.74 to 1.49, P = 0.63), surgical complication rate (OR = 1.02, 95%CI: 0.70 to 1.49, P = 0.90), nonsurgical complication rate (OR = 1.21, 95%CI: 0.54 to 2.72, P = 0.64), leakage rate (OR = 2.54, 95%CI: 0.92 to 7.01, P = 0.07), stricture rate (OR = 0.36, 95%CI: 0.09 to 1.44, P = 0.15), wound complication rate (OR = 0.71, 95%CI: 0.33 to 1.55, P = 0.39), time to first flatus (WMD = -0.10, 95%CI: -0.27 to 0.07, P = 0.26), and proximal surgical margin (WMD = -0.25, 95%CI: -1.14 to 0.65, P = 0.59) was not statistically different. Conclusion Compared with LADG BI, DA is a safe and feasible procedure, with significantly reduced blood loss, time to oral intake, and postoperative hospitalization. PMID:27631378

    The adoption of robotic systems for gastric cancer surgery has been proven feasible and safe; however, a benefit over the laparoscopic approach has not yet been well-documented. We aimed to investigate the surgical outcomes of robotic versus laparoscopic gastrectomy for gastric cancer, according to the extent of surgery and patients' obesity status. Between January 2009 and July 2011, 770 patients were enrolled in this retrospective analysis. All had stage IA/IB gastric cancer preoperatively and underwent either laparoscopic (n = 622) or robotic (n = 148) gastrectomy. Patients were classified into obese and non-obese groups on the basis of visceral fat area (VFA). The extent of surgery was defined by whether patients underwent distal or total gastrectomy. The surgical outcomes following distal gastrectomy were similar between the robotic and laparoscopic groups regardless of the obesity status. After total gastrectomy, the number of total and N2-area lymph nodes were significantly higher in the robotic group than in the laparoscopic group in non-obese patients with VFA < 100 cm(2) (total, 38.8 vs. 46.5; p = 0.018; N2 area, 9.0 vs. 12.4; p = 0.041), but no significant differences were observed in obese population. Robotic group developed less severe complications after total gastrectomy compared to laparoscopic group in non-obese patients (p = 0.036). Robotic assistance did not improve surgical outcomes over the laparoscopic approach in obese patients undergoing distal gastrectomy. However, non-obese patients with low VFA may benefit from robotic assistance during total gastrectomy in terms of radical D2 lymphadenectomy with fewer serious complications.

    Gastric cancer with pregnancy is rare and usually presents in late and advanced stage. Standard interventions in diagnosing, staging and treatment of cancer may be harmful for the fetus. The treatment of cancer in pregnancy should not differ significantly from the treatment in nonpregnant women. There have been case reports of open gastrectomy for gastric cancer in pregnancy. We present a case of early gastric cancer in a 37-year-old pregnant woman treated with laparoscopic distal gastrectomy with lymph node dissection with no postoperative complications. Laparoscopic distal gastrectomy with lymph node dissection seems to be feasible and safe in pregnancy for a mother and a fetus. PMID:28090507

    Several prospective studies on laparoscopy-assisted distal gastrectomy for early gastric cancer have been initiated, but no prospective study evaluating laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy has been completed to date. A non-randomized confirmatory trial was commenced in April 2015 to evaluate the safety of laparoscopy-assisted total gastrectomy and laparoscopy-assisted proximal gastrectomy for clinical stage I gastric cancer. A total of 245 patients will be accrued from 42 Japanese institutions over 3 years. The primary endpoint is the proportion of patients with anastomotic leakage. The secondary endpoints are overall survival, relapse-free survival, proportion of patients with completed laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy, proportion of patients with conversion to open surgery, adverse events, and short-term clinical outcomes.

    Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.

    According to the Brazilian National Institute of Cancer, gastric cancer is the third leading cause of death among men and the fifth among women in Brazil. Surgical resection is the only potentially curative treatment. The most serious complications associated with surgery are fistulas and dehiscence of the jejunal-esophageal anastomosis. Hiatal hernia refers to herniation of elements of the abdominal cavity through the esophageal hiatus of the diaphragm, though this occurrence is rarely reported as a complication in gastrectomy. A 76-year-old man was diagnosed with intestinal-type gastric adenocarcinoma. He underwent a total laparoscopic-assisted gastrectomy and D2 lymphadenectomy on May 19, 2015. The pathology revealed a pT4pN3 gastric adenocarcinoma. The patient became clinically stable and was discharged 10 days after surgery. He was subsequently started on adjuvant FOLFOX chemotherapy; however, 9 days after the second cycle, he was brought to the emergency room with nausea and severe epigastric pain. A CT scan revealed a hiatal hernia with signs of strangulation. The patient underwent emergent repair of the hernia and suffered no postoperative complications. He was discharged from the hospital 9 days after surgery. Hiatal hernia is not well documented, and its occurrence in the context of gastrectomy is an infrequent complication.

    Malnutrition is reported to be an inevitable consequence of total gastrectomy, although there are few data to support this contention. Six patients of median age 63 years underwent total gastrectomy for malignancy. At follow-up (median 45 months, range 25-60 months) each patient was clinically tumour-free and underwent dietary assessment, faecal fat and nitrogen measurement and routine haematological testing. Protein and fat stores, measured by neutron activation analysis and the tritiated water dilution technique, were compared with the same measurements made before operation and with predicted values. Mean (s.d.) dietary intake (2224(381) kcal day-1 and 81(15)g protein day-1) met the patients' estimated requirements. Mean(s.d.) serum albumin and faecal nitrogen values were normal but there was notable steatorrhoea (21(17) g day-1). Body composition measurements revealed profound deficiencies of body-weight (P less than 0.02), protein (P less than 0.01) and fat (P less than 0.02) before operation which were not corrected by an apparently curative total gastrectomy (P less than 0.05), although further deterioration was prevented.

    There may be concerns over disbenefits to patients who have chosen to undergo laparoscopic gastrectomy by experts in open gastrectomy, considering the disparity between the level of proficiency in open gastrectomy, at which they are already experts, and that in laparoscopic gastrectomy, at which they are beginners. The aim of this study was to compare surgical radicality and outcomes between laparoscopic gastrectomy and open gastrectomy during the learning period of laparoscopic gastrectomy for a senior surgeon who was already an expert in open gastrectomy. Data of short-term surgical outcomes were obtained from patients following laparoscopy assisted distal gastrectomy (LADG) by a surgeon. The initial and following 30 experiences were grouped into LADG-I and LADG-II, respectively. Patients who underwent open distal subtotal gastrectomy (ODSG) and yet could have been candidates for LADG were grouped into ODSG. Known indicators of proficiency levels and the postoperative hospital course were compared. The consequences of extended lymphadenectomy, and the radicality of surgery by completing D2 lymphadenectomy were analyzed. The LADG group revealed longer operation time and less bleeding compared to the ODSG group (P < 0.001). The number of retrieved lymph nodes and the rate of complications were not significantly different. In the LADG-I group, the D1+:D2 ratio was 4:1, showing significant differences from those in the LADG-II (0.36:1) and ODSG (0.16:1) groups (P < 0.001). The surgeon was able to complete D2 lymphadenectomy during LADG without significant change in the amount of bleeding and the rate of complications, but with a longer operation time (P = 0.009). The number of lymph nodes from the 12a station was not significantly different between the LADG and ODSG groups with D2 lymphadenectomy. The surgical outcomes were comparable between LADG and ODSG even during the learning period of LADG, and the equivalence of radicality in lymphadenectomy was soon achieved

    Tumor localization during intracorporeal anastomosis after totally laparoscopic distal gastrectomy (TLDG) is challenging. The aim of this study was to assess the simplicity and feasibility of locating tumors in the stomach using radio-opaque markers and preoperative endoscopic clipping. The intra- and postoperative findings of 29 patients who underwent TLDG with intracorporeal anastomosis between January 2012 and March 2013 were reviewed. Preoperative endoscopic clips were applied just proximal to the tumor by specialized endoscopists, and surgical gauze with an attached radio-opaque marker (3 mm × 60 mm) was prepared. The marker was fixed to either the anterior or posterior of the stomach, above the predicted site of the tumor, using suture ties. Portable abdominal radiography was used during the laparoscopic surgery, and the stomach was resected using guidance by the radiomarker. The radio-opaque marker and the endoscopic clips were clearly visible by intraoperative abdominal radiography. All patients received curative resection. No complications or deaths were encountered. The mean distance between the endoscopic clips and the radiomarker by portable intraoperative radiography was 21.3 ± 18.3 mm, whereas the actual in situ mean distance was 20.7 ± 17.6 mm. This difference was not statistically significant (P > 0.05). It is imperative that preoperative endoscopic clips are applied just proximal to the tumor by specialized endoscopists. The use of a radio-opaque marker is a simple and feasible way to locate tumors during totally laparoscopic gastrectomy.

    Long-term survival is difficult after manifestation of distant lymph node metastasis following curative resection for advanced gastric cancer. Two patients who achieved long survival with linac therapy after curative treatment of gastric cancer, are reported. Case 1: 45 years old, male. Distal gastrectomy with D2 dissection was carried out for such gastric cancer as L.M, less.Post.Ant, fType 3, T2 (MP), fStage II, on July 13, 1994. As paraaortic lymph nodes metastases was observed with CT examination on October 12, 1995, irradiation therapy using linac was conducted, and CR was achieved. Though Virchow's lymph nodes metastases was followed that episode, PR was achieved with 4,750 cGy of linac therapy. Finally, however, the patient died with metastases to lung and bone on May 19, 2002. Case 2: 62 years old, male. Distal gastrectomy with D2 + No.8p and also No.16b1 interaorticocaval dissection was conducted for such advanced gastric cancers as M, less, fType 3, T3 (SE), fStage III B on June 7, 1995. Paraaortic lymph nodes metastases were observed through CT examination on October 12, 1995. Irradiation therapy using linac resulted in CR. Virchows lymph node metastasis, which appeared on December 12, 1997, was also treated with 5,000 cGy of linac, and CR was also achieved. The patient is surviving today without recurrence.

    An 80-year-old man who had undergone distal gastrectomy and Billroth-II gastrojejunostomy 38 years previously, for a benign gastric ulcer, was diagnosed with remnant gastric cancer based on upper gastrointestinal endoscopy findings. He presented at our emergency department with acute-onset epigastric pain due to perforated remnant gastric cancer. Conservative medical management was selected, including nasogastric tube insertion, antibiotics, and proton pump inhibitors, because his peritonitis was limited to his epigastrium and his general condition was stable. Twenty-one days after the perforation occurred, curative total remnant gastrectomy and D2 lymphadenectomy were performed. Adhesion between the lateral segment of the liver and the dissected lesser curvature of the gastric remnant may have contributed to the peritonitis in this case, which was limited to the epigastrium. This is the first report of perforated remnant gastric cancer in which conservative treatment was effective prior to curative resection. The protocol reported here may be of use to other clinicians who may encounter this clinical entity in their practices. PMID:27651972

    INTRODUCTION Laparoscopic gastrectomy is rapidly expanding despite reservations by some surgeons regarding its safety and radicality. The aim of this study was to evaluate patients undergoing laparoscopic gastrectomy for both benign and malignant disease with particular emphasis on technical feasibility, safety, effectiveness and complications. PATIENTS AND METHODS Review of prospectively collected data of patients who underwent laparoscopic gastrectomy from May 2005 to September 2009 under the care of one consultant surgeon. RESULTS A total of 61 laparoscopic gastrectomies were performed (35 men and 26 women) with a median age of 68 years (range, 41–90 years). There were 39 distal gastrectomies (19 adenocarcinoma, 6 gastrointestinal stromal tumour [GIST], 4 benign gastric outlet obstruction, 4 high-grade dysplasia in gastric adenomas, 4 non-healing ulcers, 2 gastric antral vascular ectasia [GAVE]); 15 sub-total gastrectomies (13 adenocarcinomas, 2 GIST); and 7 total gastrectomies (5 adenocarcinomas, 1 GIST, 1 carcinoid). Median follow-up was for 48 months (range, 1–72 months). There was one death, two major and six minor complications. All patients with complications made a satisfactory recovery. CONCLUSIONS Laparoscopic gastrectomy is associated with a low mortality (1.75%) and major morbidity (3.50%). Although technically demanding, especially when a D2 lymphadenectomy is performed, our results have shown that tailored laparoscopic resection based on tumour characteristics with either D1 or D2 lymphadenectomy results in good surgical and oncological outcomes.

    We successfully executed laparoscopic distal gastrectomy in two patients who had previously undergone coronary artery bypass grafting using the right gastroepiploic artery (RGEA). A laparoscopic distal gastrectomy preserving the RGEA graft with Roux-en-Y reconstruction was performed on two men, one 69 years of age and one 73 years of age. In both cases, the RGEA was used during coronary artery bypass grafting for the posterior descending branch. The laparoscopic approach helped avoid injury to the RGEA associated with laparotomy and retractor placement. In addition, the locations of ports necessary for laparoscopy were situated away from the RGEA graft and from adhesions resulting from bypass. Using typical laparoscopic settings, we were able to easily identify the grafted RGEA. Thus, laparoscopic distal gastrectomy is not only less invasive than open gastrectomy procedures, but it is also associated with a lower risk of injury to the RGEA graft.

    Neonatal gastric perforation (NGP) may be spontaneous, secondary to necrotizing enterocolitis (NEC), or due to distal obstruction. A 27-week old premature male newborn presented with pneumoperitoneum. A single perforation of stomach was found at surgery. Primary repair and gastrostomy were performed. On fifth postoperative day, pneumoperitoneum was again detected. At reoperation, multiple gastric perforations of the greater curvature were found. Sleeve gastrectomy was performed. The patient responded well to the treatment. PMID:28083496

    Determine the postoperative morbidity and in-hospital mortality of gastrectomy due to gastric cancer. The study involved the review of the clinical records of all patients with histologically confirmed diagnostic of gastric adenocarcinoma, which underwent a gastrectomy at the Peruvian Institute of Neoplastic Diseases between January 1950 and December 1999. During that period, 2,033 gastrectomies were performed, 503 of which were total gastrectomies and 1,447 were distal subtotal gastrectomies. Postoperative morbidity of total and distal subtotal gastrectomy dropped from 23.7% and 14.3% during the 1950 decade, to 19.8% and 7.4% during the 1990 decade, respectively, while the in-hospital mortality of total and subtotal gastrectomy dropped from 28.9% and 19.4% during the 50s to 4.4% and 2.2% during the 90's. The most common complications were the esophagojejunal, gastrojejunal and duodenal fistulas, respiratory infections, intra-abdominal abscesses, pancreatic fistula, early intestinal obstruction, hemorrhage from the anastomosis site and surgical site infection. Multivariate logistics regression analysis showed that the risk factors for in-hospital mortality of total gastrectomy were hypoalbuminemia, intraoperative blood transfusion and re-resection (OR: 2.4, 5.9 and 1.7, respectively). For distal subtotal gastrectomy, the risk factors for in-hospital mortality were hypoalbuminemia, intraoperative blood transfusion, splenectomy and re-resection (OR: 2.6, 2.46, 2.42 and 6.3, respectively). Based on our results, the in-hospital mortality risk depends on the postoperative variables (hypoalbuminemia, intraoperative blood transfusion, splenectomy and re-resection) more than on the pre-operative variables, beyond the surgeon's control (age, sex, clinical stage, etc.).

    Dumping syndrome is a well-known adverse outcome after gastrectomy, but the precise clinical features have not been described. The aim of this study was to examine global aspects of dumping syndrome and to explore factors affecting the intensity of dumping syndrome in a large cohort using a newly developed integrated questionnaire, the Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45. Eligible questionnaires retrieved from 2,368 patients after 6 types of gastrectomy were analyzed. The incidence, intensity and number of symptoms of early general, early abdominal and late dumping syndrome were examined across various types of gastrectomy, and clinical factors affecting the intensity of each category of dumping syndrome were identified by multiple regression analysis. Dumping syndromes occurred most frequently and strongly in patients who underwent total gastrectomy with Roux-en-Y (TGRY), followed by proximal gastrectomy (PG), distal gastrectomy with Billroth-I, distal gastrectomy with Roux-en-Y, pylorus-preserving gastrectomy (PPG) and local resection (LR), in that order. Significant positive correlations among different categories of dumping syndromes were observed. TGRY, female sex, younger age, division of the celiac branch of the vagus nerve, PG and shorter postoperative period were independently related to worse dumping syndrome. Dumping syndromes were most common after TGRY and least common after PPG and LR among the various gastrectomy procedures. Type of gastrectomy and several clinical factors were related to the intensity of dumping syndrome. PGSAS-45 could offer a useful tool for evaluating dumping syndrome after gastrectomy. © 2015 S.

    For gastric cancer patients, surgical resection with en-bloc lymphadenectomy is the cornerstone of curative treatment. Open gastrectomy has long been the preferred surgical approach worldwide. However, this procedure is associated with considerable morbidity. Several meta-analyses have shown an advantage in short-term outcomes of laparoscopic gastrectomy compared to open procedures, with similar oncologic outcomes. However, it remains unclear whether the results of these Asian studies can be extrapolated to the Western population. In this trial from the Netherlands, patients with resectable gastric cancer will be randomized to laparoscopic or open gastrectomy. The study is a non-blinded, multicenter, prospectively randomized controlled superiority trial. Patients (≥18 years) with histologically proven, surgically resectable (cT1-4a, N0-3b, M0) gastric adenocarcinoma and European Clinical Oncology Group performance status 0, 1 or 2 are eligible to participate in the study after obtaining informed consent. Patients (n = 210) will be included in one of the ten participating Dutch centers and are randomized to either laparoscopic or open gastrectomy. The primary outcome is postoperative hospital stay (days). Secondary outcome parameters include postoperative morbidity and mortality, oncologic outcomes, readmissions, quality of life and cost-effectiveness. In this randomized controlled trial laparoscopic and open gastrectomy are compared in patients with resectable gastric cancer. It is expected that laparoscopic gastrectomy will result in a faster recovery of the patient and a shorter hospital stay. Secondly, it is expected that laparoscopic gastrectomy will be associated with a lower postoperative morbidity, less readmissions, higher cost-effectiveness, better postoperative quality of life, but with similar mortality and oncologic outcomes, compared to open gastrectomy. The study started on 1 December 2014. Inclusion and follow-up will take 3 and 5

    The well-organized study to support that increased cholelithiasis and bile duct dilatation can occur after gastrectomy has not been reported. The aim of this study was to determine the incidence of cholelithiasis and the degree of common bile duct (CBD) dilatation in patients undergoing subtotal gastrectomy, compared to those undergoing endoscopic treatment for gastric cancer. Patients who diagnosed with gastric cancer and received treatment at six academic referral centers were investigated for the incidence and time of cholelithiasis and the degree of CBD dilatation after treatment by analysis of 5-year follow-up CTs. The operation group underwent subtotal gastrectomy without vagotomy, while in the control group endoscopic treatment was administered for gastric cancer. A total of 802 patients were enrolled in 5-year analysis (735 patients in the operation group and 67 patients in the control group). Cholelithiasis occurred in 47 patients (6.39%) in the operation group and 3 patients (4.48%) in the control group (p=0.7909). The incidences of cholelithiasis were 4.28% in Billoth-I and 7.89% in Billoth-II (p=0.0487). The diameter of proximal CBD and distal CBD increased by 1.11 mm and 1.41 mm, respectively, in the operation group, compared to 0.4 mm and 0.38 mm, respectively, in the control group (pœ0.05). Patients with increased CBD dilatation more than 5 mm showed statistically significant increases in alkaline phosphatase and gamma-glutamyltransferase. The incidence of cholelithiasis was not increased due to subtotal gastrectomy without vagotomy, but the incidence was higher after Billoth-II compared to Billoth-I. In addition, significant change in the CBD diameter was observed after subtotal gastrectomy.

    This paper documents the first case of gastric cancer associated with Recklinghausen's disease, which was successfully treated by a totally laparoscopic operation. A 67-year-old woman with Recklinghausen's disease was referred to this department to undergo surgical treatment for early gastric cancer. The physical examination showed multiple cutaneous neurofibromas throughout the body surface, which made an upper abdominal incision impossible. Laparoscopic surgery requiring only small incisions was well indicated, and a totally laparoscopic distal gastrectomy with lymph node dissection was performed. Billroth I reconstruction was done intra-abdominally using a delta-shaped anastomosis. The patient followed a satisfactory postoperative course with no complications. Since the totally laparoscopic gastrectomy has many advantages over open surgery, it should therefore be preferentially used as a less invasive treatment in the field of gastric cancer.

    In spite of the decreasing incidence of gastric carcinoma, as it is reported in recent reports from the U.S.A., total gastrectomy and its surgical indications results and complications, focus the interest of surgeons. We analize 61 cases of total gastrectomy for carcinoma, treated in the years 1982-1992. Perioperative mortality and long term survival appear highly satisfactory, mainly if one considers that the site and extension of the neoplasms treated would have severely impaired the possibilities of cure or long term survival with surgery of lesser momentum. We believe that nowaday indications for total gastrectomy can be widened in the hope of improving results of gastric cancer surgery with no or little additional risk.

    The European Organization for Research and Treatment of Cancer quality-of-life questionnaire-OG25 was developed to evaluate the quality of life in patients with stomach and esophageal cancer. The following are included in the OG25 but not in the STO22: odynophagia, choked when swallowing, weight loss, trouble eating with others, trouble swallowing saliva, trouble talking, and trouble with coughing. In this study, we evaluated the quality of life of gastrectomized patients using both, the OG25 and the STO22. A total of 138 patients with partial gastrectomy (PG) (distal gastrectomy=91; pylorus-preserving gastrectomy= 47) and 44 patients with total gastrectomy (TG) were prospectively evaluated. Body weight and scores from the OG25 and STO22 were evaluated preoperatively and at 3 weeks, 3 months, and 6 months after surgery. Patients with TG had significant weight loss compared to patients with PG. At 3 months, TG was associated with worse scores for dysphagia, eating, odynophagia, trouble eating with others, trouble with taste, and weight loss on the OG25. TG was also associated with dysphagia, eating restrictions, and anxiety on the STO22. The OG25 helped differentiate between the groups with respect to weight loss, odynophagia, choked when swallowing, and trouble eating with others. The OG25 scores changed over time and were significantly different. The OG25 is a more sensitive and useful scale than the STO22 for evaluating the quality of life of gastrectomized patients, especially those with total gastrectomy.

An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux-en-Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.

    Purpose It is hypothesized that robotic gastrectomy may surpass laparoscopic gastrectomy after the operators acquire long-term experience and skills in the manipulation of robotic arms. This study aimed to evaluate the long-term learning curve of robotic distal gastrectomy (RDG) for gastric cancer compared with laparoscopic distal gastrectomy (LDG). Materials and Methods From October 2008 to December 2015, patients who underwent LDG (n=809) were matched to patients who underwent RDG (n=232) at a 1:1 ratio, by using a propensity score matching method after stratification for the operative year. The surgical outcomes, such as trends of operative time, blood loss, and complication rate, were compared between the two groups. Results The RDG group showed a longer operative time (171.3 minutes vs. 147.6 minutes, P<0.001) but less estimated blood loss (77.6 ml vs. 116.6 ml, P<0.001). The complication rate and postoperative recovery did not differ between the two groups. The RDG group showed a longer operative time and similar estimated blood loss compared with the LDG group after 5 years of experience (operative time: 159.2 minutes vs. 136.0 minutes in 2015, P=0.003; estimated blood loss: 72.9 ml vs. 78.1 ml in 2015, P=0.793). Conclusions In terms of short-term surgical outcomes, RDG may not surpass LDG after a long-term experience with the technique. PMID:28053810

    Objective Sleeve gastrectomy is the fastest growing surgical procedure to treat obesity in the world but it may cause or worsen gastroesophageal reflux disease. This article originally aimed to describe the addition of anti-reflux procedures (removal of periesophageal fats pads, hiatoplasty, a small plication and fixation of the gastric remnant in position) to the usual sleeve gastrectomy and to report early and late results. Methods Eighty-eight obese patients that also presented symptoms of gastroesophageal reflux disease were submitted to sleeve gastrectomy with anti-reflux procedures. Fifty of them were also submitted to a transit bipartition. The weight loss of these patients was compared to consecutive 360 patients previously submitted to the usual sleeve gastrectomy and to 1,140 submitted to sleeve gastrectomy + transit bipartition. Gastroesophageal reflux disease symptoms were specifically inquired in all anti-reflux sleeve gastrectomy patients and compared to the results of the same questionnaire applied to 50 sleeve gastrectomy patients and 60 sleeve gastrectomy + transit bipartition patients that also presented preoperative symptoms of gastroesophageal reflux disease. Results In terms of weight loss, excess of body mass index loss percentage after anti-reflux sleeve gastrectomy is not inferior to the usual sleeve gastrectomy and anti-reflux sleeve gastrectomy + transit bipartition is not inferior to sleeve gastrectomy + transit bipartition. Anti-reflux sleeve gastrectomy did not add morbidity but significantly diminished gastroesophageal reflux disease symptoms and the use of proton pump inhibitors to treat this condition. Conclusion The addition of anti-reflux procedures, such as hiatoplasty and cardioplication, to the usual sleeve gastrectomy did not add morbidity neither worsened the weight loss but significantly reduced the occurrence of gastroesophageal reflux disease symptoms as well as the use of proton pump inhibitors.

    Wernicke's encephalopathy is usually related to alcoholism, malnutrition, or hyperemesis gravidarum. We report a case of Wernicke's encephalopathy after distal gastrectomy for gastric cancer. A 58-year-old man underwent distal gastrectomy with Billroth Ⅰreconstruction for early gastric cancer. Nine months later, he developed anorexia and vomiting for a few days. Brain MRI showed no significant findings, and he resumed ingestion 5 days after admission. On the 8th day of hospitalization, dysphagia suddenly developed and brain MRI indicated Wernicke's encephalopathy. Vitamin B1 was immediately injected, and neurological symptoms gradually improved. However, dysphagia did not adequately improve, leading to severe aspiration pneumonitis. Laparoscopic gastrostomy was performed for aspiration of the stomach contents and initiation of enteral nutrition. After gastrostomy, the patient made good progress and was transferred to a rehabilitation hospital. We should recognize that gastrectomy can cause Wernicke's encephalopathy.

    AIM: To describe the application of complete robotic gastrectomy with transvaginal specimen extraction (TVSE) for gastric cancer patients. METHODS: Between July and November 2014, eight female patients who were diagnosed with gastric adenocarcinoma underwent a TVSE following a full robot-sewn gastrectomy. According to the tumor location, the patients were allocated to two different groups; two patients received robotic total gastrectomy with TVSE and the other six received robotic distal gastrectomy with TVSE. RESULTS: Surgical procedures were successfully performed in all eight cases without conversion. The mean age was 55.3 (range, 42-69) years, and the mean body mass index was 23.2 (range, 21.6-26.0) kg/m2. The mean total operative time and blood loss were 224 (range, 200-298) min and 62.5 (range, 50-150) mL, respectively. The mean postoperative hospital stay was 3.6 (range, 3-5) d. The mean number of lymph nodes resected was 23.6 (range, 17-27). None was readmitted within 30 d of postoperation. During the follow-up, no stricture developed nor was any anastomotic leakage detected. CONCLUSION: It is possible to perform a TVSE following a full robot-sewn gastrectomy with standard D2 lymph node resection for female gastric cancer patients. PMID:26715817

    Objective To evaluate the impact of subtotal (SG) versus total (TG) gastrectomy on the oncologic outcome of patients with cancer of the distal stomach from 28 Italian institutions. Summary Background Data There is controversy over whether SG and TG have a different impact on the 5-year survival probability of patients with cancer of the distal half of the stomach. Methods The present analysis involved 618 patients randomized during surgery to SG (315) or TG (303), provided there was at least 6 cm from the proximal edge of the tumor to the cardia, there was no intraperitoneal or distant spread, and it was possible to remove the tumor entirely. Both surgical treatments included regional lymphadenectomy. Results Four patients died after SG and seven after TG. Median follow-up was 72 months after SG (range 2 to 125) and 75 months after TG (range 7 to 113). Five-year survival probability as computed by the Kaplan-Meier method was 65.3% for SG and 62.4% for TG. The test of equivalence led to the conclusion that the two procedures may be considered equivalent in terms of 5-year survival probability. The analysis of survival using a multivariate Cox regression model showed a statistically significant impact on survival of tumor site, tumor spread within the gastric wall, extent of resection to the spleen plus or minus neighboring organs or structures, and relative frequency of metastasis in resected lymph nodes. Conclusions Both procedures have a similar survival probability. The authors believe that SG, which has been reported to be associated with a better nutritional status and quality of life, should be the procedure of choice, provided that the proximal margin of the resection falls in healthy tissue.

    Over a century ago, Gowers described two young patients in whom distal muscles weakness involved the hand, foot, sternocleidomastoid, and facial muscles in the other case the shoulder and distal leg musculature. Soon after, , similar distal myopathy cases were reported whereby the absence of sensory symptoms and of pathologic changes in the peripheral nerves and spinal cord at postmortem examination allowed differentiation from Charcot-Marie-Tooth disease. In 1951, Welander described autosomal dominant (AD) distal arm myopathy in a large Scandanavian cohort. Since then the number of well-characterized distal myopathies has continued to grow such that the distal myopathies have formed a clinically and genetically heterogeneous group of disorders. Affected kindred commonly manifest weakness that is limited to foot and toe muscles even in advanced stages of the disease, with variable mild proximal leg, distal arm, neck and laryngeal muscle involvement in selected individuals. An interesting consequence of the molecular characterization of the distal myopathies has been the recognition that mutation in a single gene can lead to more than one clinical disorder. For example, Myoshi myopathy (MM) and limb girdle muscular dystrophy (LGMD) type 2B are allelic disorders due to defects in the gene that encodes dysferlin. The six well described distal myopathy syndromes are shown in Table 1. Table 2 lists advances in our understanding of the myofibrillar myopathy group and Table 3 includes more recently delineated and less common distal myopathies. In the same manner, the first section of this review pertains to the more traditional six distal myopathies followed by discussion of the myofibrillar myopathies. In the third section, we review other clinically and genetically distinctive distal myopathy syndromes usually based upon single or smaller family cohorts. The fourth section considers other neuromuscular disorders that are important to recognize as they display prominent

    A 69-year-old man underwent esophagogastroduodenoscopy, which showed a slightly depressed lesion at the greater curvature of the gastric body. We diagnosed gastric adenocarcinoma of the fundic gland type(GA-FG)from examination of the biopsy specimen. Endoscopic submucosal dissection(ESD)was performed for curative resection. The pathological examination revealed a positive vertical margin. Consequently, laparoscopic gastrectomy was additionally performed. GA-FG has recently been proposed as a new entity of gastric adenocarcinoma. GA-FG mostly develops without Helicobacter pylori infection and often invades the submucosa, regardless of size. However, GA-FG rarely demonstrates lymphatic and venous invasion despite deep submucosal invasion. Since most GA-FG cases undergo ESD, few reports of surgical resection exist. Here, we report our experience of laparoscopic gastrectomy for GA-FG.

  12. Bile duct stone formation around a nylon suture after gastrectomy: A case report

    PubMed Central

    2013-01-01

    Background Many cases of choledocholiths formed around sutures and clips used during cholecystectomy have been reported. We describe a case of gallstone formation around a nylon suture after non-biliary surgery. To the best of our knowledge, this is the first report of such a case. Case presentation A 75-year-old Japanese man, who had undergone distal gastrectomy for gastric cancer and reconstruction with the Billroth II method 8 years earlier, presented with gastric discomfort. Abdominal ultrasonography was conducted and we diagnosed cholecysto-choledocholithiasis with dilatation of the intrahepatic bile duct. He underwent cholecystectomy and cholangioduodenostomy for choledocholith removal. Gallstones, which had formed around a nylon suture used during the previous gastrectomy, were found in the bile duct. Sutures of the same material had also been placed on the duodenum. Chemical analysis revealed that the stones were composed of calcium bilirubinate. The patient was discharged on postoperative day 19, and choledocholithiasis has not recurred thus far. Conclusion The findings from this case suggest that standard, non-resorbable sutures used in gastrectomy may be associated with the formation of bile duct stones; therefore, absorbable suture material may be required to avert gallstone formation even in the case of gastrectomy.

    The aim of this study is to estimate the impact of obesity on surgical outcomes of laparoscopic-assisted gastrectomy for gastric cancer. Between January 2005 and January 2010, 1100 consecutive patients who underwent laparoscopic-assisted distal gastrectomy for gastric cancer were reviewed to evaluate the impact of obesity. The patients were classified into 3 groups according to the World Health Organization classification, as normal weight [body mass index (BMI) 18.5 to 24.9 kg/m], overweight (BMI 25 to 29.9 kg/m), and obese patients (BMI ≥30 kg/m). The postoperative complication rates for normal weight, overweight, and obese patients were 5.7%, 10.0%, 15.4%, respectively. Overweight and obese patients had a significantly prolonged operation time, increased intraoperative blood loss, prolonged first flatus, day of commencement of soft diet, increased number of administration of analgesics, and prolonged hospital stay. Overweight and obesity were associated with poor early surgical outcomes of laparoscopic-assisted gastrectomy. This study suggested that greater cautions and improved surgical techniques were required to improve early surgical outcomes of laparoscopic-assisted gastrectomy for overweight and obese patients.

    Postgastrectomy syndrome (PGS) remains a common complication after gastrectomy that affects patients' quality of life. Although impaired gastrointestinal (GI) function by gastrectomy procedures is thought to be the cause, the precise pathophysiology of PGS is yet to be clarified. The aim of this study was to investigate relationships between GI function and various symptoms or alimentary status in patients after gastrectomy. Fifty-one patients who underwent total or distal gastrectomy at least 1 year previously were studied. All patients replied to a questionnaire that asked presence of symptoms (esophageal reflux, nausea, abdominal pain, early satiation, diarrhea, early dumping general, early dumping abdominal, and late dumping symptoms) and alimentary status (change in body weight, food intake per meal, frequency of meals per day). They also underwent assessment of GI function consisting of gastric emptying study by (13)C-acetate breath test to examine reservoir capacity and gastric emptying, and water load drink test to evaluate tolerance to volume loading (TVL). The relationships between GI function and each symptom or alimentary status were examined. The patients with nausea and early dumping general symptoms had significantly smaller reservoir capacity*, the patients with diarrhea and early dumping general symptoms had significantly faster gastric emptying*, and the patients with early satiation and early dumping abdominal symptoms had significantly impaired TVL*. Significant correlations were identified between TVL and body weight changes* or food intake per meal* (* p < 0.05). Impaired postoperative GI function was closely related to symptoms or worse alimentary status.

    The aim of this study was to elucidate the role of PTBD in patients with DSL and ALS post-gastrectomy for malignancy or benign ulcer perforation. Percutaneous transhepatic biliary drainage (PTBD) is an interventional radiologic procedure used to promote bile drainage. Duodenal stump leakage (DSL) and afferent loop syndrome (ALS) can be serious complications after gastrectomy. From January 2002 through December 2014, we retrospectively reviewed 19 patients who underwent PTBD secondary to DSL and ALS post-gastrectomy. In this study, a PTBD tube was placed in the proximal duodenum near the stump or distal duodenum in order to decompress and drain bile and pancreatic fluids. Nine patients with DSL and 10 patients with ALS underwent PTBD. The mean hospital stay was 34.3 days (range, 12-71) in DSL group and 16.4 days (range, 6-48) in ALS group after PTBD. A liquid or soft diet was started within 2.6 days (range, 1-7) in the ALS group and within 3.4 days (range, 0-15) in the DSL group after PTBD. One patient with DSL had PTBD changed, and 2 patients with ALS underwent additional surgical interventions after PTBD. The PTBD procedure, during which the tube was inserted into the duodenum, was well-suited for decompression of the duodenum as well as for drainage of bile and pancreatic fluids. This procedure can be an alternative treatment for cases of DSL and ALS post-gastrectomy.

    The standard approach to laparoscopic sleeve gastrectomy (LSG) involves sleeve-forming through a vertical gastrectomy, producing a narrow, tubular stomach. Considerable laparoscopic skills are required to find a suitable size at which the pressure of the sleeve is not excessive and the restriction is sufficient for obtaining good weight-loss effect without increasing the risk of complications. There is no doubt that considerable technical details are required to create a “perfect sleeve.” We report our sleeve-forming technique for LSG involving both vertical gastrectomy and plication, which we have termed “laparoscopic plicated sleeve gastrectomy.” This technique was shown to be safe and efficacious for the treatment of severe obesity and can reduce technical difficulties in the creation of a “perfect sleeve.”

    In traditional practice patterns, physicians take care of all clinical decisions, such as diagnosis, treatment, and recovery. In the Nippon Medical School Hospital a clinical pathway for distal gastrectomy patients, recorded as a post-operative care map, was introduced in August 2000. In January 2001 the post-operative management was analyzed and standardization of practice was carried out with printed order sets, such as drugs and infusion solutions. The aim of this study was to evaluate the clinical significance of the clinical pathway for gastrectomy patients by employing standardized postoperative management and printed order sets. From January 2001 to December 2001, 87 patients underwent distal (43), total (28), proximal (7) and partial gastrectomy (9) for gastric cancer (stage IA: 47, IB: 9, II: 7, IIIA: 8, IIIB 2, IV: 10) and gastrointestinal stromal tumor (4). These patients were randomly assigned to either the main building or the east building of our hospital. In the main building 38 patients were looked after using traditional practice (control group). In the east building 47 patients were looked after according to the clinical pathway (path group) and 2 patients were excluded from the path group because of neo-adjuvant chemotherapy and severe heart failure. Aspects of the patients' outcomes, including length of stay, the first day of the diet, morbidity, and medical costs, were compared between the path group and the control group. All data were expressed as means+/-standard deviation. Statistical analyses were made using Student t-test, Mann-Whitney U-test, and chi(2) test, and the 5%level was chosen for statistical significance. The length of the hospital stay was 27.1+/-10.0 and 40.8+/-26.1 days (p<0.005) and the length of post-operative stay was 18.1+/-9.5 and 28.2+/-22.3 days (p<0.01) in the path group and the control group, respectively. The post-operative day when the diet was started for the path and control groups was 6.8+/-8.9 and 8

    Summary Background After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. Material/Methods Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed. Results Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively. Conclusions Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.

    We report two cases for anesthetic management of gastrectomy for gastric cancer which took place after receiving coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA). The first patient was a 75-year-old man after CABG using the RGEA 14 years before. He was diagnosed with gastric cancer and was scheduled for total gastrectomy. Preoperative coronary angiography (CAG) showed complete occlusion of the right coronary artery (RCA), whereas RGEA was patent. Because percutaneous coronary intervention (PCI) was hard to perform on the occluded RCA, proximal gastrectomy was carried out without lymph node dissection. The surgeons judged the surgery enough for radical treatment. Surgery was accomplished without any problems. The second patient was a 76-year-old man after CABG using the RGEA 15 years before. He was diagnosed with advanced gastric cancer and was scheduled for distal gastrectomy. Preoperative CAG showed the RCA partially occluded and the RGEA remaining patent. He received the scheduled surgery after confirmation of the success of PCI, performed preoperatively for reperfusion of the occluded segments. Although the RGEA was incised during the surgery, gastrectomy was accomplished without any problems in the cardiac function.

    It is still controversial whether patients with a history of gastrectomy have high risk of esophageal carcinogenesis. On the other hand, the treatment strategy for esophageal cancer patients after gastrectomy is complicated. The association between histories of gastrectomy and esophageal carcinogenesis was retrospectively analyzed, and the treatment of esophageal cancer patients after gastrectomy was evaluated based on questionnaire data collected from multiple centers in Kyushu, Japan. The initial subject population comprised 205 esophageal cancer patients after gastrectomy. Among them, 108 patients underwent curative surgical treatment, and 70 patients underwent chemoradiation therapy (CRT). The time between gastrectomy and esophageal cancer development was longer in peptic ulcer patients (28.3 years) than in gastric cancer patients (9.6 years). There were no differences in the location of esophageal cancer according to the gastrectomy reconstruction method. There were no significant differences in the clinical background characteristics between patients with and without a history of gastrectomy. Among the 108 patients in the surgery group, the 5-year overall survival rates for stages I (n = 30), II (n = 18), and III (n = 60) were 68.2%, 62.9%, and 32.1%, respectively. In the CRT group, the 5-year overall survival rate of stage I (n = 29) was 82.6%, but there were no 5-year survivors in other stages. The 5-year overall survival rate of patients with CR (n = 33) or salvage surgery (n = 10) was 61.2% or 36%, respectively. For the treatment of gastrectomized esophageal cancer patients, surgery or CRT is recommended for stage I, and surgery with or without adjuvant therapy is the main central treatment in advanced stages, with surgery for stage II, neoadjuvant therapy + surgery for stage III, and CRT + salvage surgery for any stage, if the patient's condition permits. © 2015 The Authors.

    Although a few studies have reported the use of reduced-port laparoscopic gastrectomy (RPG) in gastric cancer patients, the feasibility of routinely using this technique remains unclear. It is therefore important to evaluate the surgical advantages of this technique in this patient group. Between August 2010 and July 2015, 165 patients underwent RPGs at our hospital, performed by a single surgeon. Of these patients, 88 underwent reduced-port laparoscopic distal gastrectomy (RPLDG) and 77 underwent reduced-port laparoscopic total gastrectomy (RPLTG). In addition to short-term surgical outcomes after RPG, survival times and the surgical learning curve were also evaluated. Blood losses during lymph node dissection in the RPLDG and RPLTG groups were not significantly different (p = 0.160). Conversion to open surgery was necessary in only two patients. Postoperative morbidities were observed in 14.8 % of the RPLDG group and 14.3 % of the RPLTG group, but there were no deaths. Most patients expressed high cosmetic satisfaction in both groups. In the RPLDG group, operation time during reconstruction decreased over the first 50 cases and then plateaued, as the surgeon's experience of the technique increased. In contrast, in the RPLTG group, operation times dropped with surgical experience for both lymph node dissection, plateauing after 40 cases, and for reconstruction, plateauing after 30 cases. Only three patients died of gastric cancer in the follow-up period and three patients died of other diseases. Five-year overall survival and 5-year disease-specific survival were 95.6 and 98.0 %, respectively. We have shown that reduced-port gastrectomy (RPG) could be an acceptable and satisfactory procedure for treating gastric cancer for an experienced laparoscopic gastric surgeon who has sufficient previous experience of conventional laparoscopic gastrectomies.

    Identify prognostic factors associated to total or proximal gastrectomy with or without splenectomy and / or distal pancreatectomy in patient with proximal gastric cancer. Evaluate the frequency of lymph node metastasis to the hilum and splenic artery, postoperative morbidity and mortality and the impact of lymphadenectomy of group 10 and 11 on long term survival. We performed an observational, descriptive, longitudinal and retrospective study analyzing patients with diagnostic of proximal third gastric adenocarcinoma subjected to total or proximal gastrectomy with or without splenectomy or distal pancreatectomy in the service of Abdomen of the Instituto Nacional de Enfermedades Neoplásicas between 1990 and 2005. Overall survival for each of the groups was calculated using the Kaplan-Meier method, prognostic factors were evaluated using univariate and multivariate analysis. We studied 219 patients with proximal third gastric adenocarcinoma (cardias and bottom), of wich, according to inclusion criteria, only qualify 129 (N=129): 22 (17.1%) were treated by gastrectomy alone, 79 (61.2%) gastrectomy associated witch splenectomy and 28 (21.7%) gastrectomy with distal pancreatosplenectomy, constituting three treatment groups. We compared the survival of each group and each factor analyzed, determining the following prognostic factors: lymph node metastasis (N2-N3), degree of differentiation, undifferentiated tumors and Borrmann III and IV tumors. Neither splenectomy or distal pancreatectosplenectomy improved survival compared to the gastrectomy alone. The morbidity and mortality was higher in patients with more aggressive but more aggressive surgery without significant value. The number of nodes removed in patients who had pancreatosplenectomy and /or splenectomy was higher, however, had no impact on survival at 5 years.

    Obesity and bariatric surgery (BS) are increasing worldwide and can potentially lead to incidental diagnosis of benign gastric tumor including gastric leiomyoma (GL). When indicated, local tumor enucleation, completed through laparoscopic minimal-invasive approaches, has proven to be safe and effective especially when located near the esophagogastric junction (EGJ) with limited morbidity as compared to partial or total gastrectomies. Little is known regarding the most appropriate strategy concerning the management of GL regardless of the location in patients' candidate for BS. We present the case of a 67-year-old morbidly obese woman. She presented with an incidental 3-cm GL developed near the EGJ and antral histologic abnormalities mandating a gastric follow-up. Therefore, we performed both laparoscopic transgastric enucleation and sleeve gastrectomy simultaneously. After identification of the lesion, the gastrocolic ligament was divided and a gastrotomy was performed along the greater curvature to expose the tumor. Once the submucosal plan was identified, the lesion was enucleated from the submucosamuscle junction. After closure of the mucosal defect and ensuring the absence of gastric wall perforation, a conventional laparoscopic sleeve gastrectomy was performed. No adverse outcomes occurred during the post-operative period. The final pathologic diagnosis showed a completely resected and benign leiomyoma. Herein, we report the first laparoscopic transgastric enucleation of a GL localized close to the EGJ performed concomitant with a sleeve gastrectomy. This combined approach appeared feasible, safe, and do not compromise the access to the GI tract as well as potential future curative treatments on the gastric sleeve.

    NASA's Johnson Space Center (JSC) and the Astromaterials Curator are charged by NPD 7100.10D with the curation of all of NASA s extraterrestrial samples, including those from future missions. This responsibility includes the development of new sample handling and preparation techniques; therefore, the Astromaterials Curator must begin developing procedures to preserve, prepare and ship samples at sub-freezing temperatures in order to enable future sample return missions. Such missions might include the return of future frozen samples from permanently-shadowed lunar craters, the nuclei of comets, the surface of Mars, etc. We are demonstrating the ability to curate samples under cold conditions by designing, installing and testing a cold curation glovebox. This glovebox will allow us to store, document, manipulate and subdivide frozen samples while quantifying and minimizing contamination throughout the curation process.

    Regional lymph node metastases are an important predictor of survival for patients with resectable adenocarcinoma of the stomach. Currently, the number of lymph nodes examined is frequently less than requirements for accurate staging. Clinical factors associated with lymph node recovery are understood poorly. We performed a retrospective chart review of 99 consecutive patients who underwent gastrectomy for gastric adenocarcinoma distal to the gastroesophageal junction to determine clinical variables associated lymph node recovery. Ninety-nine patients underwent gastrectomy for gastric adenocarcinoma at our two hospitals. More than 15 lymph nodes were examined in 64% of specimens. Univariate analysis showed an association between the number of lymph nodes recovered and the number of positive nodes, lymphadenectomy extent, hospital, surgeon, and pathology technician (p < 0.001). Multivariate analysis identified the pathology technician as the most important healthcare-related variable contributing to the variation of lymph node recovery, using fixed- (p < 0.001) and random-effects models. This study suggests that the pathology technician is an important healthcare-related factor influencing lymph node recovery after gastrectomy. In identifying potential areas benefiting from a systems improvements approach, focus on the technical aspects of specimen processing may be of benefit in maximizing the number of lymph nodes recovered.

    AIM: To evaluate the radicalness and safety of laparoscopic D2 dissection for gastric cancer. METHODS: Clinicopathological data from 209 patients with gastric cancer, who underwent radical gastrectomy with D2 dissection between January 2007 and February 2011, were analyzed retrospectively. Among these patients, 131 patients underwent laparoscopy-assisted gastrectomy (LAG) and 78 underwent open gastrectomy (OG). The parameters analyzed included operative time, blood loss, blood transfusion, morbidity, mortality, the number of harvested lymph nodes (HLNs), and pathological stage. RESULTS: There were no significant differences in sex, age, types of radical resection [radical proximal gastrectomy (PG + D2), radical distal gastrectomy (DG + D2) and radical total gastrectomy (TG + D2)], and stages between the LAG and OG groups (P > 0.05). Among the two groups, 127 cases (96.9%) and 76 cases (97.4%) had 15 or more HLNs, respectively. The average number of HLNs was 26.1 ± 11.4 in the LAG group and 24.2 ± 9.3 in the OG group (P = 0.233). In the same type of radical resection, there were no significant differences in the number of HLNs between the two groups (PG + D2: 21.7 ± 7.5 vs 22.4 ± 9.3; DG + D2: 25.7 ± 11.0 vs 22.3 ± 7.9; TG + D2: 30.9 ± 13.4 vs 29.3 ± 10.4; P > 0.05 for all comparisons). Tumor free margins were obtained in all cases. Compared with OG group, the LAG group had significantly less blood loss, but a longer operation time (P < 0.001). The morbidity of the LAG group was 9.9%, which was not significantly different from the OG group (7.7%) (P = 0.587). The mortality was zero in both groups. CONCLUSION: Laparoscopic D2 dissection is equivalent to OG in the number of HLNs, regardless of tumor location. Thus, this procedure can achieve the same radicalness as OG. PMID:22371644

    Objective Laparoscopic sleeve gastrectomy is a widely accepted and effective bariatric surgery method. The rate of leakage at the staple-line has been reported to be between 1.5 and 5%. Aside from the use of percutaneous drainage, re-laparoscopy, or abdominal sepsis control by laparotomy, endoscopic esophagogastric stent placement is increasingly preferred as a treatment method. Because laparoscopic sleeve gastrectomy is a widely used modality in our hospital, we aimed to evaluate the rate of leaks and the results of stent placements in our patients. Material and Methods Between January 1st 2010 and August 31st 2014, laparoscopic sleeve gastrectomy was performed on 236 patients by three surgeons. The demographic information and postoperative discharge summaries were collected and analyzed with the permission of the hospital ethics committee. Information about leak treatment management was also collected. Results Leaks after laparoscopic sleeve gastrectomy in four patients were stented in the first postoperative month. Short (12 cm) Hanora® (M.I.Tech, Gyeonggi-do, Korea) self-expandable coated stents were placed in two patients, and long (24 cm) Hanora® self-expandable coated stents were placed in the other two. The stents were removed after one month in two patients, two and a half months later in one, and five months later in another patient. The leaks were demonstrated to be healed in all patients after stent removal. Endoscopic stent revision was performed in one patient due to migration of the stent and in another for stent breakage. Conclusion The success rate of treatment of leaks after laparoscopic sleeve gastrectomy by stent placement has been variable in the literature. The success in early stent placement has been shown to be related to physician expertise. According to the results of our patients, we suggest that endoscopic stent placement in the early stage after controlling sepsis is an effective method in the management of leaks. PMID:28149125

    Recently, the right gastroepiploic artery (RGEA) has been used in coronary artery bypass graft (CABG) as an alternative arterial graft. Because of the improvement of prognosis after CABG, malignant diseases are more common in older patients. However, there is a serious problem in patients with gastric cancer after CABG with RGEA graft. In these patients, an interruption of coronary blood supply through the RGEA may cause a life-threatening myocardial ischemia. Therefore, an appropriate strategy is very important to avoid risk while retaining the curability of the operation. We herein describe a 76-year-old Japanese man with advanced gastric cancer who underwent CABG using the RGEA. Abdominal computed tomography (CT) showed #6 lymph nodes (sub-pyloric lymph nodes) metastases surrounding the RGEA. We concluded that curative resection was impossible while preserving the RGEA and started combination chemotherapy using S-1 and cisplatin. After 2 courses of that, #6 lymph nodes were reduced extremely. Thereafter the patient underwent distal gastrectomy with regional lymph node dissection around the RGEA without excision of the RGEA. Histologically, there were no metastases in #6 lymph nodes. Neoadjuvant chemotherapy may be effective for preserving the RGEA graft in a patient with advanced gastric cancer after CABG.

    AIM: To identify the incidence and etiology of anemia after gastrectomy in patients with long-term follow-up after gastrectomy for early gastric cancer. METHODS: The medical records of those patients with early gastric adenocarcinoma who underwent curative gastrectomy between January 2006 and October 2007 were reviewed. Patients with anemia in the preoperative workup, cancer recurrence, undergoing systemic chemotherapy, with other medical conditions that can cause anemia, or treated during follow up with red cell transfusions or supplements for anemia were excluded. Anemia was defined by World Health Organization criteria (Hb < 12 g/dL in women and < 13 g/dL in men). Iron deficiency was defined as serum ferritin < 20 μg/dL. Vitamin B12 deficiency was defined as serum vitamin B12 < 200 pg/mL. Iron deficiency anemia was defined as anemia with concomitant iron deficiency. Anemia from vitamin B12 deficiency was defined as megaloblastic anemia (mean cell volume > 100 fL) with vitamin B12 deficiency. The profile of anemia over 48 mo of follow-up was analyzed. RESULTS: One hundred sixty-one patients with gastrectomy for early gastric cancer were analyzed. The incidence of anemia was 24.5% at 3 mo after surgery and increased up to 37.1% at 48 mo after surgery. The incidence of iron deficiency anemia increased during the follow up and became the major cause of anemia at 48 mo after surgery. Anemia of chronic disease and megaloblastic anemia were uncommon. The incidence of anemia in female patients was significantly higher than in male patients at 12 (40.0% vs 22.0%, P = 0.033), 24 (45.0% vs 25.0%, P = 0.023), 36 (55.0% vs 28.0%, P = 0.004), and 48 mo (52.0% vs 31.0%, P = 0.022) after surgery. Patients with total gastrectomy showed significantly higher incidence of anemia than patients with subtotal gastrectomy at 48 mo after surgery (60.7% vs 31.3%, P = 0.008). The incidence of iron deficiency was significantly higher in female patients than in male patients at 6 (35.4% vs

    We aimed to investigate the efficacy of postoperative early intervention with an elemental diet to reduce weight loss and enhance recovery after gastrectomy. Nutritional status and gastrointestinal immune function tend to worsen, and postoperative weight loss is inevitable in these patients; therefore, improvement in their postoperative condition is important, especially in gastric cancer patients aged ≥80 years. Clinical outcomes and postoperative nutritional status were compared between 21 and 22 consecutive elderly patients aged ≥80 years who underwent distal gastrectomy before and after the introduction of postoperative oral elemental diet (Elental®, 300 kcal/day), respectively, between October 2011 and June 2016. A significant reduction in postoperative complications was noted in the nutrition support group (N-group) as compared with the control group (C-group). In particular, the prevalence of systemic complications was significantly lower in the N-group (33.3 vs. 4.5 %, p = 0.015), whereas no significant difference was observed in the prevalence of locoregional complications. The percentage of weight loss and reduction in BMI from 1 month to 1 year after surgery was significantly lower in the N-group (p = 0.012 each). The nutrition status (albumin, total protein, hemoglobin, and C-reactive protein levels) at 1 month after surgery showed improvements (p = 0.005, p = 0.048), and hospital stay was decreased in the N-group as compared to the C-group (16.0 vs. 12.5 days, p = 0.041). Early intervention with an elemental diet after distal gastrectomy is valuable for reducing perioperative weight loss and improving nutritional management and may be associated with enhanced postoperative recovery in elderly patients.

    Purpose The purpose of this study was to determine the effect of a prior gastrectomy on the difficulty of subsequent colonoscopy, and to identify the surgical factors related to difficult colonoscopies. Materials and Methods Patients with a prior gastrectomy who had undergone a colonoscopy between 2011 and 2014 (n=482) were matched (1:6) to patients with no history of gastrectomy (n=2,892). Cecal insertion time, intubation failure, and bowel clearance score were compared between the gastrectomy and control groups, as was a newly generated comprehensive parameter for a difficult/incomplete colonoscopy (cecal intubation failure, cecal insertion time >12.9 minutes, or very poor bowel preparation scale). Surgical factors including surgical approach, extent of gastrectomy, extent of lymph node dissection, and reconstruction type, were analyzed to identify risk factors for colonoscopy performance. Results A history of gastrectomy was associated with prolonged cecal insertion time (8.7±6.4 vs. 9.7±6.5 minutes; P=0.002), an increased intubation failure rate (0.1% vs. 1.9%; P<0.001), and a poor bowel preparation rate (24.7 vs. 29.0; P=0.047). Age and total gastrectomy (vs. partial gastrectomy) were found to be independent risk factors for increased insertion time, which slowly increased throughout the postoperative duration (0.35 min/yr). Total gastrectomy was the only independent risk factor for the comprehensive parameter of difficult/incomplete colonoscopy. Conclusions History of gastrectomy is related to difficult/incomplete colonoscopy performance, especially in cases of total gastrectomy. In any case, it may be that a pre-operative colonoscopy is desirable in selected patients scheduled for gastrectomy; however, it should be performed by an expert endoscopist each time. PMID:27752394

    Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

    AIM: To investigate the necessity and correctness of acid suppression pre- and post-gastrectomy among gastric carcinoma (GC) patients. METHODS: From June 2011 to April 2013, 99 patients who were diagnosed with GC or adenocarcinoma of the gastroesophageal junction (type II or III) and needed surgical management were enrolled. They all underwent gastrectomy by the same operators [35 undergoing total gastrectomy (TG) plus Roux-en-Y reconstruction, 34 distal gastrectomy (DG) plus Billroth I reconstruction, and 30 proximal gastrectomy (PG) plus gastroesophagostomy]. We collected and analyzed their gastrointestinal juice and tissues from the pre-operational day to the 5th day post-operation, and 6 mo post-surgery. Gastric pH was detected with a precise acidity meter. Gastric juice contents including potassium, sodium and bicarbonate ions, urea nitrogen, direct and indirect bilirubin, and bile acid were detected using Automatic Biochemical Analyzer. Data regarding tumor size, histological type, tumor penetration and tumor-node-metastasis (TNM) stage were obtained from the pathological records. Reflux symptoms pre- and 6 mo post-gastrectomy were evaluated by reflux disease questionnaire (RDQ) and gastroesophageal reflux disease questionnaire (GERD-Q). SPSS 16.0 was applied to analyze the data. RESULTS: Before surgery, gastric pH was higher than the threshold of hypoacidity (4.25 ± 1.45 vs 3.5, P = 0.000), and significantly affected by age, tumor size and differentiation grade, and potassium and bicarbonate ions; advanced malignancies were accompanied with higher pH compared with early ones (4.49 ± 1.31 vs 3.66 ± 1.61, P = 0.008). After operation, gastric pH in all groups was of weak-acidity and significantly higher than that pre-gastrectomy; on days 3-5, comparisons of gastric pH were similar between the 3 groups. Six months later, gastric pH was comparable to that on days 3-5; older patients were accompanied with higher total bilirubin level, indicating more serious

    Background and Objectives: Recent studies have supported minimally invasive techniques as a viable alternative to open surgery in the treatment of gastric cancer. The goal of this study is to review our institution's experience with totally laparoscopic gastrectomy for the treatment of both early- and advanced-stage gastric cancer. Methods: A retrospective study was conducted to examine the short-term outcomes of laparoscopic gastrectomy performed at Monmouth Medical Center between May 2003 and June 2012. We reviewed postoperative complications, surgical margins, number of resected lymph nodes, estimated blood loss, length of stay, narcotic use, and recurrence rate. Results: Forty patients were included in the study. There were 21 cases of adenocarcinoma, 15 cases of gastrointestinal stromal tumor, 2 cases of carcinoid, 1 case of small cell neuroendocrine tumor, and 1 case of squamous cell carcinoma. The mean operative time was 220 minutes (range, 67–450 minutes). The median length of stay was 6 days (range, 1–37 days). The mean number of harvested lymph nodes was 11. Early postoperative complications occurred in 7 patients and included anastomotic stricture, wound infection, intra-abdominal abscess, bowel obstruction, and esophageal pneumatosis. There were two deaths. The Kaplan-Meier 5-year overall and recurrence-free survival rate for all cases of adenocarcinoma was 63.2%. Conclusions: Totally laparoscopic gastrectomy is a reasonable option for the treatment of gastric malignancy, with early data showing acceptable survival rates and perioperative outcomes. Large-scale randomized trials are still needed to confirm oncologic equivalency to open gastrectomy in patients with advanced disease. PMID:24398204

    With the increasing popularity of sleeve gastrectomy, many stomach specimens are being evaluated. Understanding the significance and treatment for unexpected pathology is important. This study examines the incidence of relevant histopathology of sleeve gastrectomy specimens. It evaluates previous data for each histopathology and provides recommendations for treatment. In this study, a retrospective review was performed for 241 patients who underwent sleeve gastrectomy from 2009 to 2014 at a single institution. Of the specimens, 122 had no significant histopathology, 91 had gastritis, 13 had lymphoid aggregates, 5 had hyperplasia, 3 had intestinal metaplasia, 3 had gastrointestinal stromal tumors (GISTs), and 3 had gastric polyps. Of the GISTs all had a low mitotic rate and the size of the tumor ranged from 1.5 to 4.5 cm. The findings of metaplasia may be a marker for increased risk of malignancy and may require additional surveillance. The findings of GIST may warrant interval imaging to survey for recurrence, though the likelihood of recurrence for the tumors in this study is less than 2 per cent based on previous studies.

    It is well known that old age is a risk factor for postoperative complications. Therefore, this study aimed to explore the risk factors for poor postoperative surgical outcomes in elderly gastric cancer patients. Between January 2006 and December 2015, 247 elderly gastric cancer patients who underwent curative gastrectomy were reviewed. In this study, an elderly patient was defined as a patient aged ≥65 years. All possible variables were used to explore the risk factors for poor early surgical outcomes in elderly gastric cancer patients. Based on multivariate analyses of preoperative risk factors, preoperative low serum albumin level (<3.5 g/dl) and male sex showed statistical significance in predicting severe postoperative complications. Additionally, in an analysis of surgery-related risk factors, total gastrectomy was a risk factor for severe postoperative complications. Our study findings suggest that low serum albumin level, male sex, and total gastrectomy could be risk factors of severe postoperative complications in elderly gastric cancer patients. Therefore, surgeons should work carefully in cases of elderly gastric cancer patients with low preoperative serum albumin level and male sex. We believe that efforts should be made to avoid total gastrectomy in elderly gastric cancer patients.

    PURPOSE We aimed to evaluate the relationship between gastrectomy and the volume of liver segments II and III in patients with gastric cancer. METHODS Computed tomography images of 54 patients who underwent curative gastrectomy for gastric adenocarcinoma were retrospectively evaluated by two blinded observers. Volumes of the total liver and segments II and III were measured. The difference between preoperative and postoperative volume measurements was compared. RESULTS Total liver volumes measured by both observers in the preoperative and postoperative scans were similar (P > 0.05). High correlation was found between both observers (preoperative r=0.99; postoperative r=0.98). Total liver volumes showed a mean reduction of 13.4% after gastrectomy (P = 0.977). The mean volume of segments II and III showed similar decrease in measurements of both observers (38.4% vs. 36.4%, P = 0.363); the correlation between the observers were high (preoperative r=0.97, P < 0.001; postoperative r=0.99, P < 0.001). Volume decrease in the rest of the liver was not different between the observers (8.2% vs. 9.1%, P = 0.388). Time had poor correlation with volume change of segments II and III and the total liver for each observer (observer 1, rseg2/3=0.32, rtotal=0.13; observer 2, rseg2/3=0.37, rtotal=0.16). CONCLUSION Segments II and III of the liver showed significant atrophy compared with the rest of the liver and the total liver after gastrectomy. Volume reduction had poor correlation with time.

    To evaluate laparoscopic re-sleeve gastrectomy as a treatment of weight regain after Sleeve. Laparoscopic sleeve gastrectomy is a common bariatric procedure. Weight regain after long-term follow-up is reported. Patients were considered for laparoscopic re-sleeve gastrectomy when we observed progressive weight regain and persistence of comorbidities associated with evidence of dilated gastric fundus and/or antrum on upper gastro-intestinal series. Follow-up visits were scheduled at 1, 3, 6 and 12 mo after surgery and every 6 mo thereafter. Measures of change from baseline at different times were analyzed with the paired samples t test. We observed progressive weight regain after sleeve in 11 of the 201 patients (5.4%) who had a mean follow-up of 21.1 ± 9.7 mo (range 6-57 mo). Three patients started to regain weight after 6 mo following Sleeve, 5 patients after 12 mo, 3 patients after 18 m. Re-sleeve gastrectomy was always performed by laparoscopy. The mean time of intervention was 55.8 ± 29.1 min. In all cases, neither intra-operative nor post-operative complications occurred. After 1 year follow-up we observed a significant (P < 0.05) mean body mass index reduction (-6.6 ± 2.7 kg/m(2)) and mean % excess weight loss (%EWL) increase (+31.0% ± 15.8%). An important reduction of antihypertensive drugs and hypoglycemic agents was observed after re-sleeve in those patients affected by hypertension and diabetes. Joint problems and sleep apnea syndrome improved in all 11 patients. Laparoscopic re-sleeve gastrectomy is a feasible and effective intervention to correct weight regain after sleeve.

    BACKGROUND Gastric cancer has a high incidence in the elderly in the UK, with a significant number of patients aged 75 years or more. While surgery forms the mainstay of treatment, evidence pertaining to the management of gastric cancer in the Western population in this age group is scarce. METHODS We retrospectively reviewed the outcomes of laparoscopy-assisted total and distal gastrectomies at our centre from 2005 to 2015. Patients aged 70 years or above were included in the elderly group. RESULTS A total of 60 patients underwent laparoscopy-assisted gastrectomy over a 10-year period, with a predominance of male patients. There was no significant difference in the rate of overall surgical and non-surgical complications, in-hospital mortality, operation time and length of hospital stay, between the elderly and non-elderly groups. Univariate analysis, performed for risk factors relating to anastomotic leak and surgical complications, showed that age over 70 years and higher American Association of Anesthesiologists grades are associated with a higher, though not statistically significant, number of anastomotic leaks (P = 1.000 and P = 0.442, respectively) and surgical complications (P = 0.469 and P = 0.162, respectively). The recurrence rate within the first 3 years of surgery was significantly higher in the non-elderly group compared with the elderly group (Log Rank test, P = 0.002). There was no significant difference in survival between the two groups (Log Rank test, P = 0.619). CONCLUSIONS Laparoscopy-assisted gastrectomy is safe and feasible in an elderly population. There is a need for well-designed, prospective, randomised studies with quality of life data to inform our practice in future.

    Cancer gastrectomy seems to benefit type 2 diabetes; however, results are conflicting. In a prospective protocol, including retrospective information, the aim was assessment of changes in glucose profile in patients with both normal and deranged preoperative glucose homeostasis. Patients (N = 164) with curative subtotal or total Roux-en-Y gastrectomy for gastric cancer (n = 92), or Roux-en-Y gastric bypass for morbid obesity (RYGB, n = 72) were preoperatively classified into diabetes (including prediabetes) and control group. Postoperative diabetes outcome was stratified as responsive or refractory, and results in controls were correspondingly defined as stable or new-onset diabetes (NOD), according to fasting blood glucose and HbA1c. Dietary intake and biochemical profile was documented. Statistical methods included analysis of variance, multivariate logistic regression, and propensity score matching according to postoperative weight loss. Age of cancer cases was 67.9 ± 11.5 years, 56.5 % males, initial body mass index (BMI) 24.7 ± 3.7, current BMI 22.6 ± 3.8 kg/m(2), and follow-up 102.1 ± 51.0 months, whereas in bariatric individuals age was 51.4 ± 10.1 years, 15.3 % males, initial BMI 56.7 ± 12.2, current BMI 34.8 ± 8.1 kg/m(2), and follow-up 104.1 ± 29.7 months. Refractory disease corresponded to 62.5 % (cancer) versus 23.5 % (bariatric) (P = 0.019), whereas NOD represented 69.2 versus 23.8 % respectively (P = 0.016). Weight loss (ΔBMI) was associated with diabetes response in cancer patients but not with NOD. No difference between subtotal and total gastrectomy was detected. Divergent outcomes (refractory vs. responsive) were confirmed in BMI-similar, propensity-matched cancer gastrectomy patients with preoperative diabetes, consistent with weight-dependent and -independent benefits. Diabetes response was confirmed, however with more refractory cases than in bariatric controls, whereas high proportions of NOD occurred. Such dichotomous pattern seems

    Subtotal gastrectomy (i.e., partial removal of the stomach), a surgical treatment for early-stage distal gastric cancer, is usually accompanied by highly selective vagotomy and Billroth II reconstruction, leading to dramatic changes in the gastric environment. Based on accumulating evidence of a strong link between human gut microbiota and host health, a 2-year follow-up study was conducted to characterize the effects of subtotal gastrectomy. Gastric microbiota and predicted gene functions inferred from 16S rRNA gene sequencing were analyzed before and after surgery. The results demonstrated that gastric microbiota is significantly more diverse after surgery. Ralstonia and Helicobacter were the top two genera of discriminant abundance in the cancerous stomach before surgery, while Streptococcus and Prevotella were the two most abundant genera after tumor excision. Furthermore, N-nitrosation genes were prevalent before surgery, whereas bile salt hydrolase, NO and N2O reductase were prevalent afterward. To our knowledge, this is the first report to document changes in gastric microbiota before and after surgical treatment of stomach cancer.

    The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis. Recent genetic and physiologic studies have greatly expanded our understanding of how the distal convoluted tubule regulates these processes at the molecular level. This article provides an update on the distal convoluted tubule, highlighting concepts and pathophysiology relevant to clinical practice. PMID:24855283

    The ferric chloride intoxication is frequently caused by accident. Its toxicity is generally underrated, which can lead to fatal evolution or irreversible consequences. In this case, the caustic condition of the substance is related to the toxic properties of iron. A 36-year-old male patient arrives by ambulance indicating sensory deterioration. He presents erosive injuries in the buccal cavity and in the oropharynx, brownish teeth and metabolic acidosis. Toxicology tests and ferritin blood dosage are requested, which show a result from 1400 mg/dl. The symptoms are interpreted as acute iron intoxication. Due to the unfavorable evolution of his condition, an abdominal and pelvic CT scan are performed, which show extensive pneumoperitoneum and free fluid in the abdominal cavity. An exploratory laparotomy, a total gastrectomy with esophagostomy and feeding jejunostomy, washing and drainage due to perforated gastric necrosis caused by caustic ingestion are performed. In our country, there is a high rate of intoxication caused by iron compounds, although it is not statistically measured. Nevertheless, the ferric chloride intoxication is extremely infrequent. The ingestion of this product leads to complications, which are associated with the iron concentration and its condition as a caustic agent. The surgical indications in the presence of intoxication caused by iron compounds are: stomach evacuation of iron, gastric necrosis, perforation or peritonitis and stenosis. Early or prophylactic gastrectomy is contraindicated. However, if complications that require immediate surgical intervention arise, there should be no hesitation and the corresponding procedure should be performed.

    AIM To identify certain clinical factors other than the type of gastrectomy which affect the postoperative quality of life (QOL) of patients after gastrectomy. METHODS The postgastrectomy syndrome assessment scale (PGSAS)-45 was designed to assess the severity of symptoms, the living status and the QOL of gastrectomized patients. It consists of 45 items, of which 22 are original items while 23 were retrieved from the SF-8 and Gastrointestinal Symptoms Rating Scale questionnaires with permission. A nationwide surveillance study to validate PGSAS was conducted and 2368 gastric cancer patients who underwent various types of gastrectomy at 52 medical institutions were enrolled. Of these, 1777 patients who underwent total gastrectomy (TG) reconstructed with Roux-Y (n = 393), distal gastrectomy (DG) reconstructed with Billroth-I (n = 909), or DG reconstructed with Roux-Y (n = 475) were evaluated in the current study. The influence of the type of gastrectomy and other clinical factors such as age, sex, duration after surgery, the symptom severity, the degree of weight loss, dietary intake, and the ability for working on the postoperative QOL (i.e., dissatisfaction for daily life subscale, physical component summary and mental component summary of the SF-8) were examined by multiple regression analysis (MRA). In addition, importance of various symptoms such as esophageal reflux, abdominal pain, meal-related distress, indigestion, diarrhea, constipation and dumping on the postoperative living status and QOL were also appraised by MRA. RESULTS The postoperative QOL were significantly deteriorated in patients who underwent TG compared to those after DG. However, the extent of gastrectomy was not an influential factor on patients’ QOL when adjusted by the MRA. Among various clinical factors, the symptom severity, ability for working, and necessity for additional meals were the most influential factors to the postoperative QOL. As for the individual symptoms, meal

    This study investigated anatomical variations in the confluence types of the right gastroepiploic vein (RGEV) to improve knowledge regarding no. 6 lymphadenectomy for laparoscopic gastrectomy.The RGEV drainage patterns of 144 patients who were diagnosed with gastric cancer and underwent laparoscopic distal gastrectomy at our department from July 2010 to June 2011 were prospectively collected and retrospectively analyzed, and we compared the impact of different drainage patterns on no. 6 lymphadenectomy.The RGEV confluence types were classified into 6 categories in this study. Types I, II, and III, which were observed in 53 (36.8%), 27 (18.8%), and 21 (14.6%) cases, respectively, were the most frequently found during gastrectomy. All 3 of these types included a gastropancreatic trunk and were defined as the gastropancreatic group (GP group). In addition, 15 cases (10.4%) were categorized as type IV, 19 (13.2%) were categorized as type V, and 9 (6.3%) were categorized as type VI. These 3 types, which could form a gastrocolic trunk, were defined as the gastrocolic group (GC group). No significant differences were found with respect to the clinicopathological characteristics, postoperative morbidity, perioperative mortality, and 3-year overall survival rates after surgery between the 2 groups (all P > 0.05). However, the mean no. 6 lymph node (No. 6 LN) dissection time, the mean blood loss due to No. 6 LN dissection and the rate of infrapyloric vascular injury were significantly increased in the GC group compared with the GP group (all P < 0.05).The RGEV exhibits 6 types of drainage patterns, and the division points of this vein during laparoscopic gastrectomy depend on the different drainage patterns. For types IV, V, and VI, the surgeon should carefully vascularize and divide the RGEV above its confluences during surgery.

    Purpose Lymph node (LN) metastasis is the best prognostic indicator in non-distant metastatic advanced gastric cancer. This study aimed to assess the prognostic value of various clinicopathologic factors in node-negative advanced gastric cancer. Materials and Methods We retrospectively analyzed the clinical records of 254 patients with primary node-negative stage T2~4 gastric cancer. These patients were selected from a pool of 1,890 patients who underwent radical resection at Memorial Jin-Pok Kim Korea Gastric Cancer Center, Inje University Seoul Paik Hospital between 1998 and 2008. Results Of the 254 patients, 128 patients (50.4%), 88 patients (34.6%), 37 patients (14.6%), and 1 patient (0.4%) had T2, T3, T4a, and T4b tumors, respectively. In a univariate analysis, operation type, T-stage, venous invasion, tumor size, and less than 15 LNs significantly correlated with tumor recurrence and cumulative overall survival. In a multivariate logistic regression analysis, tumor size, venous invasion, and less than 15 LNs significantly and independently correlated with recurrence. In a multivariate Cox proportional hazards analysis, tumor size (hazard ratio [HR]: 2.926; 95% confidence interval [CI]: 1.173~7.300; P=0.021), venous invasion (HR: 3.985; 95% CI: 1.401~11.338; P=0.010), and less than 15 LNs (HR: 0.092; 95% CI: 0.029~0.290; P<0.001) significantly correlated with overall survival. Conclusions Node-negative gastric cancers recurred in 8.3% of the patients in our study. Tumor size, venous invasion, and less than 15 LNs reliably predicted recurrence as well as survival. Aggressive postoperative treatments and timely follow-ups should be considered in cases with these characteristics. PMID:27752393

    The Authors report their initial experience with the construction of a J-pouch as restorative surgery following total gastrectomy (TG) for malignant neoplasms. In the last 10 months of the 1990 upon 52 interventions for gastric cancer 31 TG were performed, and in 13 cases a J-pouch on the proximal end of the jejunal segment was constructed. No mortality or specific morbidity was registered using the totally stapled technique. Within one month 3/4 of the patients had normal meals as far as quantity and quality; also the foamy regurgitation seemed to be minimal. The ease of the reconstructive technique and the short term results obtained encourage the use of such approach.

    Robot-assisted gastrectomy has been reported to be a safe alternative to both conventional laparoscopy and the open approach for treating early gastric carcinoma. Currently, there are a limited number of published reports on this technique in the literature. We assessed the current status of robotic and laparoscopic surgery in the treatment of gastric cancer and compared the operative outcomes, learning curves, and oncological outcome of the two approaches. Robotic gastrectomy offers benefits that include increased ease of performing D2 lymph node dissection and reduced blood loss compared with laparoscopic gastrectomy. However, the operative time is longer, and robotic gastrectomy is more costly for the patients. Regarding to the operative and oncological outcomes, there appears to be no significant differences between laparoscopic and robotic gastrectomies after the surgeon overcomes the associated learning curves. Sharing the available knowledge regarding laparoscopic and robotic gastrectomies could shorten these learning curves. For elder patients, minimally invasive surgery that decreases the postoperative recovery time should be considered the preferred treatment. Prospective randomized studies are required to compare the surgical and oncological outcomes among laparoscopic, robotic, and open surgeries for both early and advanced gastric cancer.

    Phase III evidence in the shape of a series of randomized controlled trials and meta-analyses has shown that laparoscopic gastrectomy is safe and gives better short-term results with respect to the traditional open technique for early-stage gastric cancer. In fact, in the East laparoscopic gastrectomy has become routine for early-stage gastric cancer. In contrast, the treatment of advanced gastric cancer through a minimally invasive way is still a debated issue, mostly due to worries about its oncological efficacy and the difficulty of carrying out an extended lymphadenectomy and intestinal reconstruction after total gastrectomy laparoscopically. Over the last ten years the introduction of robotic surgery has implied overcoming some intrinsic drawbacks found to be present in the conventional laparoscopic procedure. Robot-assisted gastrectomy with D2 lymphadenectomy has been shown to be safe and feasible for the treatment of gastric cancer patients. But unfortunately, most available studies investigating the robotic gastrectomy for gastric cancer compared to laparoscopic and open technique are so far retrospective and there have not been phase III trials. In the present review we looked at scientific evidence available today regarding the new high-tech surgical robotic approach, and we attempted to bring to light the real advantages of robot-assisted gastrectomy compared to the traditional laparoscopic and open technique for the treatment of gastric cancer.

    High body mass index (BMI) and high visceral fat area (VFA) are known to be a preoperative risk factor for laparoscopic gastrectomy (LG) for gastric cancer. However, the impact of obesity on LG still remains controversial. In the present study, we compared the operative outcomes of LG with those of OG in patients with BMI of 30 kg/m(2) or more. Seventy-seven patients who underwent distal or total gastrectomy for gastric cancer were enrolled. The patients were divided into two groups by approach method; an OG group (n = 19) and a LG group (n = 62). Aquarius iNtuition(®) program was used to measure VFA. The operation time, estimated blood loss, complication rate, the number of retrieved lymph nodes, and patient survival were compared between two groups. The mean BMI and VFA were 31.6 kg/m(2) and 195.3 cm(2). The complication rate was 42.1 % in OG group and 14.5 % in LG group, respectively (P = 0.010). LG group showed less estimated blood loss (P = 0.030) and fast recovery of bowel movement (P < 0.001). However, there were no significant differences in operation time, the number of retrieved lymph nodes, and the length of hospital stay between two groups. In subgroup analysis, there was significant correlation between estimated blood loss and VFA (R (2) = 0.113, P = 0.014), but there was no correlation between operation time and VFA (R(2) = 0.002, P = 0.734). In stage I, the 5-year survival was not different between two groups (P = 0.220). LG showed better operative outcomes compared with OG, in terms of less estimated blood loss, fast recovery of bowel movement, and low complication rate, in patients with BMI of ≥ 30 kg/m(2) or more.

    Several reports have discussed the potential for reducing port access in laparoscopic sleeve gastrectomy (LSG); however, each approach had its innate setbacks. Aiming at improving the aesthetic outcome, we report a novel approach to the LSG where we place the trocars at the bikini line in what we described as bikini line sleeve gastrectomy (BLSG). The present work is a prospective, pilot study on the use of BLSG in patients, during the period between April and October 2016. Exclusion criteria included the following: large hiatal hernia, upper abdominal surgery, and xiphi-umbilical, xiphi-symphysis pubis, and xiphi-anterior superior iliac spine distances of > 25,36 and 33 cm, respectively. Four trocars were used: one at the umbilicus and three at the bikini line. All laparoscopic graspers were bariatric length instruments (43 cm). However, camera telescope, endoscopic stapler, and bipolar dissectors were standard length. Twenty eight patients underwent BLSG. The mean age was 34.6 ± 3.7 years with a mean BMI of 42.46 kg/m(2) ± 3. There were no major intra- or postoperative complications and no conversion to conventional port site placement. Patient's scar satisfaction was favorable. The mean postoperative BMI and weight at 6 m were 28.5 ± 1 kg/m(2) and 79.8 kg ± 2, respectively. The mean percentage excess weight loss at 3, 6, and 12 months were 39.5 ± 4.6, 64.5 ± 5, and 69.8 ± 6%, respectively. BLSG was found to be potentially safe, feasible, and effective with a favorable aesthetic outcome; it could possibly be offered to a select group of patients that are conscious about their scar appearance.

    Ghrelin is mainly secreted from the stomach and plays a role in appetite, weight gain, and the promotion of a positive energy balance. The levels of ghrelin decrease immediately after gastrectomy. We herein investigated the effect of the administration of synthetic ghrelin to treat postoperative severe weight loss in a prospective, one-arm clinical trial to develop new strategies for weight gain. Ten patients (four distal gastrectomy and six total gastrectomy) received ghrelin treatment. Eligibility criteria included patients who underwent gastrectomy more than 1 year previously and 15 % body weight loss from the preoperative weight or a body mass index under 19. Synthetic human ghrelin (3 μg/kg) was administered to the patients twice a day for 1 week. Oral intake of calories, appetite [evaluated using the visual analog scale (VAS)], and body weight before and during administration of ghrelin were compared. There was a significant difference in the oral food intake before and during treatment (before treatment: 1236 ± 409 kcal vs. during treatment: 1398 ± 365 kcal, p = 0.039), and the VAS for appetite significantly improved with each day of ghrelin administration (p < 0.05). Significant amounts of body weight were gained (39.5 ± 6.8 vs. 40.1 ± 6.9, p = 0.037). The administration of synthetic ghrelin improved the food intake and was effective for treating appetite loss and body weight loss. Synthetic ghrelin may be a promising new therapy for severe body weight loss following gastrectomy.

    Different outcomes after resection of gastric cancer between various ethnic patient groups have been described. It remains unclear whether disparity of treatment forms, disease-related variables, or individual patients accounts for this effect. In the 10 years between 1989 and 1999, 75 patients with gastric adenocarcinoma underwent gastrectomy at a single institution, with constant surgical standards during this time period, including complete (R0) resection attempt and extended lymphadenectomy. Ethnicity, disease characteristics, and treatment variables were analysed for their impact on survival. There were 40 males and 35 females, with a median age of 67 years (range 31-97). The gastrectomy extent was total (n=25), proximal (n=18), subtotal (n=17), distal (n=14), and segmental (n=1). The mean lymph-node count was 25+/-17 (SD). There was one post-operative death, and an overall complication rate of 27%; the median hospital stay was 11 days. Overall actuarial 5-year survival was 33% (95% CI: 19-47); potentially curable disease (stage 1A-IIIB) led to a median survival of 49 months. Asian (n=18) and Hispanic patients (n=20) had significantly better survival than Caucasian (n=31) or other patients (n=6) (P=0.01). Ethnicity was linked to the location of the primary tumour ( P=0.002), the gastrectomy extent (P=0.003), and the patient's prior abdominal operation (P=0.01) or tobacco history (P=0.03), but not to resection extent parameters (such as number of lymph nodes retrieved) or differences in pathologic characteristics. When controlling for differences of disease site, stage, R status, and patient comorbidity, ethnicity did not retain an independent prognostic impact on survival. Obvious survival differences after gastrectomy for gastric adenocarcinoma favouring Asian and Hispanic patients in this experience can be explained by different disease patterns (distal location), the related need for fewer extensive procedures (such as total gastrectomy), and diminished

    Cancer chemotherapy provides variably effective treatment for the majority of forms of human cancer and curative treatment for some 12 categories of cancer. Curative treatment is defined as the proportion of patients who survive beyond the time after which the risk of treatment failure approaches zero, i.e., the disease-free survival plateau. This progress has resulted from a closely integrated scientific effort, including drug development, pharmacology, preclinical modeling, experimental design with respect to clinical trials, quantitative criteria for response, and a series of clinical trials (initially in children with acute lymphocytic leukemia) in which the importance of complete remission, of dose and schedule, of sequencing chemotherapeutic agents, of pharmacological sanctuaries, and particularly of combination chemotherapy was studied. The principles derived from these studies, particularly those relating to combination chemotherapy, resulted in curative treatment for disseminated Hodgkin's disease, non-Hodgkin's lymphoma, pediatric solid tumors, testicular cancer, and limited small cell lung cancer. Many patients with certain stages of solid tumors, such as breast cancer and osteogenic sarcoma, are at high risk of having disseminated microscopic disease. Experimental studies indicate that treatment which is only partially effective against macroscopic disease is much more effective against microscopic tumors. Therefore chemotherapy is administered immediately following control of the primary tumor in patients at high risk of having disseminated microscopic disease, a treatment known as adjuvant chemotherapy. This program has been highly successful in increasing the cure rate in patients with pediatric solid tumors and in prolonging disease-free survival in patients with premenopausal breast cancer. Given dissemination of the technology, it is estimated that 15,000-30,000 patients per year are potentially curable in the United States. Curability of cancer

    AIM: To examine the quality of surgical care and long-term oncologic outcome after D2 gastrectomy for gastric cancer. METHODS: From 1999 to 2008, a total of 109 consecutive patients underwent D2 gastrectomy without routine pancreaticosplenectomy in a multimodal setting at our institution. Oncologic outcomes together with clinical and histopathologic data were analyzed in relation to the type of surgery performed. Staging was carried out according to the Union for International Cancer Control criteria of 2002. Patients were followed-up for five years at the outpatient clinic. The primary measure of outcome was long-term survival with the quality of surgery as a secondary outcome measure. Clinical data were retrospectively collected from the patient records, and causes of death were obtained from national registries. RESULTS: A total of 109 patients (58 men) with a mean age of 67.4 ± 11.2 years underwent total gastrectomy or gastric resection with D2 lymph node dissection. The tumor stage distribution was as follows: stage I, (27/109) 24.8%; stage II, (31/109) 28.4%; stage III, (41/109) 37.6%; and stage IV, (10/109) 9.2%. Forty patients (36.7%) received chemotherapy or chemoradiotherapy. The five-year overall survival rate for all 109 patients was 45.0%, and was 47.1% for the 104 patients treated with curative R0 resection. The five-year disease-specific survival rates were 53.0% and 55.8%, respectively. In a multivariate analysis, body mass index and tumor stage were independent prognostic factors for overall survival (both P < 0.01), whereas body mass index, tumor stage, tumor site, Lauren classification, and lymph node invasion were prognostic factors for cancer-specific survival (all P < 0.05). Postoperative 30-d mortality was 1.8% and 30-d, surgical (including three anastomotic leaks, two of which were treated conservatively), and general morbidities were 26.6%, 12.8%, and 14.7%, respectively. CONCLUSION: D2 dissection is a safe surgical option for gastric

    Glucksman, Myron L

    2010-01-01

    This article explores the phenomenon of love in the therapeutic relationship and its role as a curative factor. Since Freud's (1915) description of transference love, a major goal of treatment is to understand its developmental antecedents. Most analysts agree that transference love is no different than ordinary love, except that it is overdetermined and requires the patient to view it as simultaneously real and illusory without reciprocity from the analyst. Nontransferential, realistic elements of the therapeutic relationship also play an important role in treatment. An important outgrowth of the therapeutic process is the development of a new object relationship between analyst and patient. This special or transformative friendship is a new object relationship characterized by genuine feelings of mutual respect, trust, caring, and even love. It facilitates the patient's capacity to form and maintain other loving relationships. Two case presentations are illustrative.

    As a complicated symbiotic system, intestinal flora is reported closely related to the development of type 2 diabetes recently. Sleeve gastrectomy is one of the approaches of bariatric surgery and could improve blood glucose control in type 2 diabetes patients. This study was to explore the relationship between remodeled intestinal flora and glucose metabolism in diabetic rats. 20 male diabetic rats were operated; 10 of them underwent sleeve gastrectomy, and 10 of them underwent sham operation. Meanwhile 10 male normal rats underwent sleeve gastrectomy as control. The animals' weight and FBG had been measured. The composition changes of intestinal flora were detected by 16S rDNA sequence analysis. In diabetic rats, weight and fasting blood glucose decreased significantly after sleeve gastrectomy. However, there was no significant change for weight and blood glucose in normal rats after operation. The intestinal flora of diabetic rats reduced in the proportion of Firmicutes and increased in the proportion of Bacteroidetes after sleeve gastrectomy. The change of dominant microorganisms in intestinal flora might play an important role in the glucose metabolism.

    Although over 3000 da Vinci Surgical System (DVSS) devices have been installed worldwide, robotic surgery for gastric cancer has not yet become widely spread and is only available in several advanced institutions. This is because, at least in part, the advantages of robotic surgery for gastric cancer remain unclear. The safety and feasibility of robotic gastrectomy have been demonstrated in several retrospective studies. However, no sound evidence has been reported to support the superiority of a robotic approach for gastric cancer treatment. In addition, the long-term clinical outcomes following robotic gastrectomy have yet to be clarified. Nevertheless, a robotic approach can potentially overcome the disadvantages of conventional laparoscopic surgery if the advantageous functions of this technique are optimized, such as the use of wristed instruments, tremor filtering and high-resolution 3-D images. The potential advantages of robotic gastrectomy have been discussed in several retrospective studies, including the ability to achieve sufficient lymphadenectomy in the area of the splenic hilum, reductions in local complication rates and a shorter learning curve for the robotic approach compared to conventional laparoscopic gastrectomy. In this review, we present the current status and discuss issues regarding robotic gastrectomy for gastric cancer.

    To summarize the surgical technique and perioperative management of laparoscopic sleeve gastrectomy (LSG). A total of 57 morbid obesity patients undergoing LSG surgery from May 2010 to December 2012 were enrolled in the study, whose clinical data in perioperative period were analyzed retrospectively. These patients had more than 1 year of follow-up. All the patients received preoperative preparation and postoperative management, and postoperative excess weight loss(EWL%) and improvement of preoperative complications was evaluated. All the cases completed the operation under laparoscopy, except 1 case because of the abdominal extensive adhesion. The average operation time was(102.0±15.2) min and the mean intraoperative blood loss (132.3±45.6) ml. Of 2 postoperative hemorrhage patients, 1 case received conservative treatment, and another one underwent laparoscopic exploration. The EWL% at 3 months, 6 months and 1 year after procedure was (54.9±13.8)%, (79.0±23.6)% and (106.9±25.1)% respectively. The preoperative complications were improved in some degree. There were no operative death, and anastomotic leak, anastomotic stenosis, or surgical site infection occurred. LSG is a safe and effective surgical technique, whose safety and efficacy may be increased by improving the perioperative management.

    Background and Objectives: There is no standardized method of reconstruction in laparoscopic proximal gastrectomy (LPG). We present a novel technique of reconstruction with a long, narrow gastric tube in LPG for early gastric cancer (EGC). Methods: During the laparoscopic procedure, the upper part of the stomach is fully mobilized with perigastric and suprapancreatic lymphadenectomy, and then the abdominal esophagus is transected. After a minilaparotomy is created, the entire stomach is pulled outside. A long, narrow gastric tube (20 cm long, 3 cm wide) is created with a linear stapler. The proximal part of the gastric tube is formed into a cobra head shape for esophagogastric tube anastomosis, which is then performed with a 45-mm linear stapler under laparoscopic view. The end of the esophagus is fixed on the gastric tube to prevent postoperative esophageal reflux. Results: Thirteen patients with early proximal gastric cancer underwent the procedure. The mean operative time was 283 min, and median blood loss was 63 ml. There were no conversions to open surgery, and no intraoperative complications. Conclusion: This new technique of reconstruction after LPG is simple and feasible. The procedure has the potential of becoming a standard reconstruction technique after LPG for proximal EGC.

  10. How much does curation cost?

    PubMed Central

    2016-01-01

    NIH administrators have recently expressed concerns about the cost of curation for biological databases. However, they did not articulate the exact costs of curation. Here we calculate the cost of biocuration of articles for the EcoCyc database as $219 per article over a 5-year period. That cost is 6–15% of the cost of open-access publication fees for publishing biomedical articles, and we estimate that cost is 0.088% of the cost of the overall research project that generated the experimental results. Thus, curation costs are small in an absolute sense, and represent a miniscule fraction of the cost of the research. PMID:27504008

    To systematically review efficacyand safety of robotic gastrectomy (RG) compared with conventional laparoscopic gastrectomy (LG) for gastric carcinoma. A systematic literature search was carried out using PubMed, Cochrane Library, CBM, CNKI, WanFang, VIP and other sources like relevant references to obtain comparative studies assessing the effectiveness and safety between RG and LG published between 2013 and 2016. Then the literature was screened and the data were extracted by 2 independent reviewers. The quality of the literature was assessed, and the data analyzed using Stata/SE 14 software. Fixed effects or random effects models wereapplied according to heterogeneity. A total of 12 non-randomized observational clinical studies involving 3,580 patients were included, of which 1,096 had undergone RG and 2,484 had received LG. The results of the meta-analysis showed in terms of effectiveness, RG was associated with less blood loss, less time to first flatus and greater number of harvested lymph nodes, but there were no significant differences in proximal and distal resection margins, compared with LG. In terms of efficiency, RG was associated with shorter hospital stay, but longer operative time. In terms of safety, there were no statistically significant differences in complications, mortality and conversions between RG and LG. RG can achieve comparable or better short-term and radical effects than LG, with respect to effectiveness, efficiency and safety in treatment of gastric carcinoma. Future studies involving RG should focus on decreasing operative time and reducing cost. Moreover, there is a need for randomized controlled trials comparing the two techniques with long-term follow-up.

    STARDUST, a NASA Discovery-class mission, is the first to return samples from a comet. Grains from comet Wild 2's coma-the gas and dust envelope that surrounds the nucleus-will be collected as well as interstellar dust. The mission which launched on February 7, 1999 will encounter the comet on January 10, 2004. As the spacecraft passes through the coma, a tray of silica aerogel will be exposed, and coma grains will impact there and become captured. Following the collection, the aerogel tray is closed for return to Earth in 2006. A dust impact mass spectrometer on board the STARDUST spacecraft will be used to gather spectra. of dust during the entire mission, including the coma passage. This instrument will be the best chance to obtain data on volatile grains, which will not be well-collected in the aerogel. The dust impact mass spectrometer will also be used to study the composition of interstellar grains. In the past 5 years, analysis of data from dust detectors aboard the Ulysses and Galileo spacecraft have revealed that there is a stream of interstellar dust flowing through our solar system. These grains will be captured during the cruise phase of the STARDUST mission, as the spacecraft travels toward the comet. The sample return capsule will parachute to Earth in February 2006, and will land in western Utah. Once on y the ground, the sample return capsule will be placed into a dry nitrogen environment and flown to the curation lab at JSC.

    Transphyseal distal humerus fractures typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. Prompt and accurate diagnosis of a transphyseal distal humerus fracture is crucial for a successful outcome. Recognizing that the forearm is not aligned with the humerus on plain radiographs may aid in the diagnosis of a transphyseal distal humerus fracture. Surgical management is most commonly performed with the aid of an arthrogram. Closed reduction and percutaneous pinning techniques similar to those used for supracondylar humerus fractures are employed. Cubitus varus caused by a malunion, osteonecrosis of the medial condyle, or growth arrest is the most common complication encountered in the treatment of transphyseal distal humerus fractures. A corrective lateral closing wedge osteotomy can be performed to restore a nearly normal carrying angle.

    Four cases of arrest of distal ulnar physeal growth occurring in children ages 7 to 13 years had follow-up for 2 to 10 years. Each patient developed bowing of the radial diaphysis, ulnar translation of the distal radial epiphysis, and increased ulnar angulation of the distal radiocarpal joint surface. Growth discrepancies were documented in both the ulna (range 2.2 to 3.9 cm) and to a lesser extent the radius (range 0.2 to 1.6 cm) when compared to the opposite forearm in each patient. The progression of deformity appeared to be greatest during adolescence. Radial deviation and pronation were limited to varying degrees in each case. No patient had significant pain or functional impairment, but the cosmetic appearance was always displeasing. Indications for surgical treatment include increasing ulnar angulation of the distal radial articular surface, progressive loss of motion, and displeasing cosmetic appearance.

    1966-01-01

    The administration of pancreozymin and secretin to eight control patients and 18 patients after partial gastrectomy caused no rise in serum amylase levels above normal. Four postgastrectomy patients had unexplained elevations of basal serum lipase levels but in only one did the lipase increase above the basal level after stimulation. Duodenal aspirates from the control group and from one patient with a Billroth I gastrectomy showed a wide range of values for volume, bicarbonate and amylase content. This would appear to limit the diagnostic value of the test. The two-tube method used for collecting duodenal contents proved difficult. PMID:20328564

    Transvaginal endoscopic gastric surgery is one of the cutting edge procedures in the field of natural orifice translumenal endoscopic surgery (NOTES). Its feasibility has been shown sporadically in bariatric cases but not in oncologic conditions. The authors report their early experience with hybrid transvaginal NOTES gastrectomy for gastric submucosal tumors (SMTs). Two female patients with SMTs in the distal stomach participated in this institutional review board (IRB)-approved study. Surgical indication was determined according to the National Comprehensive Cancer Network (NCCN) sarcoma guidelines, and the study adhered to the following oncologic principles: no direct handling of the lesion, full-thickness resection, and reasonable surgical margins. The study protocol required a minimum of two laparoscopic ports to ensure procedural safety and aforementioned oncologic appropriateness. Under laparoscopic guidance, a transvaginal route was created and secured with a 50-cm flexible overtube. A gastrointestinal endoscope was introduced, and the perigastric dissection was performed using an insulation-tipped diathermy knife (IT knife) and needle knife. This process was assisted with two laparoscopic graspers. After perigastric mobilization, the transvaginal endoscope was replaced with a digital stapling device, and partial gastrectomy was accomplished. The resected specimen was isolated and delivered through the vagina, and the vaginal wound was closed under direct vision. Outcomes measurements included surgical results, pain scoring, and clinical outcomes. Both operations were completed successfully in compliance with the aforementioned oncologic principles. The operating time was 365 and 170 min, respectively. The estimated blood loss was negligible. A minilaparotomy for specimen delivery was successfully avoided in both cases. A minimal vaginal incision was added for one patient at retrieval. Postoperatively, both patients reported no pain and recovered rapidly

    Morbid obesity affects the function of the transplanted heart either directly, by damaging many elements that affect cardiac function or indirectly, by the initial appearance or worsening of co-morbidities that affect the heart. Bariatric surgery is the most effective treatment for a significant and sustained decrease in weight and it leads to the disappearance of co-morbidities such as diabetes, hypertension and dyslipidemia in high rates. These diseases can damage the blood vessels of the graft and impair its function. We report a case study of a 47-year-old morbidly obese male (BMI 36 kg/m2] who underwent heart transplantation three years previously, developed gradual weight gain and symptoms of aggravating heart failure. Coronary artery disease in the implanted heart was diagnosed. Clinically, he started suffering from shortness of breath and chest pain during minimal effort. In addition, he also suffered from high blood pressure and kidney failure. Laparoscopic sleeve gastrectomy was successfully performed and he was discharged four days later. On follow-up the patient has lost 35 kg. His present weight is 74 kg (BMI 25.7). All symptoms of heart failure improved and oral medications for hypertension and heart failure were withdrawn. Our conclusion is that it is justified to consider bariatric surgery in heart transplant recipients suffering from morbid obesity, as long as the long-term benefit outweighs the surgical risk. The decision to perform bariatric surgery should be made by a multidisciplinary team and the operation should take place at a center with extensive experience in bariatric surgery.

    Introduction. The placement of ring or band around the gastric tube might prevent the dilation after Laparoscopic Sleeve Gastrectomy (LSG). We describe the first randomized study comparing LSG and Laparoscopic Banded Sleeve Gastrectomy (LBSG). Material and Method. Fifty obese patients were enrolled in the study between January 2014 and January 2015. We analysed differences in operative time, complication rate, mortality, and BMI between the two groups over a period of 12 months. Results. Twenty-five patients received LSG (group A) and 25 LBSG (group B). The mean preoperative BMI was 47.3 ± 6.58 kg/m2 and 44.95 ± 5.85 kg/m2, respectively, in the two groups. There was no statistical relevant difference in operative time. No intraoperative complications occurred. Mean BMI registered after 3, 6, and 12 months in groups A and B, respectively, were 37.86 ± 5.72 kg/m2 and 37.58 ± 6.21 kg/m2 (p = 0.869), 33.64 ± 6.08 kg/m2 and 32.03 ± 5.24 kg/m2 (p = 0.325), and 29.72 ± 4.40 kg/m2 and 27.42 ± 4.47 kg/m2 (p = 0.186); no statistical relevant difference was registered between the two groups. Conclusion. LBSG is a safe and feasible procedure. The time required for the device positioning did not influence significantly the surgical time. The results of bodyweight loss did not document any statistically significant differences among the two groups, even though LBSG group showed a mean BMI slightly lower than that of the control group.

    The number of elderly patients undergoing gastrectomy for gastric cancer is increasing. Yet, although elderly patients are at high risk of postoperative pneumonia, no study has sufficiently investigated which clinicopathological factors are significant risk factors for the development of this complication after gastrectomy with lymph node dissection. We reviewed the medical records of 750 patients who underwent gastrectomy between January 2010 and May 2012, to establish the incidence of postoperative pneumonia (Clavien-Dindo grade II or higher). Univariate and multivariate analyses were performed to identify the risk factors for postoperative pneumonia. Thirty-two patients (4.3 %) suffered postoperative pneumonia, diagnosed as grades I, II, IIIa, and IVa, in 2 (0.3 %), 28 (3.7 %), 1 (0.2 %), and 1 (0.2 %) patient(s), respectively. Univariate analysis revealed that age (≥75 years), sex (male), diabetes mellitus (DM), a history of smoking, and impairment of respiratory function were significantly associated with postoperative pneumonia. Multivariate analysis revealed that age, impaired postoperative respiratory function, DM, and blood transfusion were independent risk factors for postoperative pneumonia. Age, impaired postoperative respiratory function, DM, and blood transfusion were identified as independent risk factors for postoperative pneumonia after gastrectomy.

  5. Curating the innate immunity interactome

    PubMed Central

    2010-01-01

    Background The innate immune response is the first line of defence against invading pathogens and is regulated by complex signalling and transcriptional networks. Systems biology approaches promise to shed new light on the regulation of innate immunity through the analysis and modelling of these networks. A key initial step in this process is the contextual cataloguing of the components of this system and the molecular interactions that comprise these networks. InnateDB (http://www.innatedb.com) is a molecular interaction and pathway database developed to facilitate systems-level analyses of innate immunity. Results Here, we describe the InnateDB curation project, which is manually annotating the human and mouse innate immunity interactome in rich contextual detail, and present our novel curation software system, which has been developed to ensure interactions are curated in a highly accurate and data-standards compliant manner. To date, over 13,000 interactions (protein, DNA and RNA) have been curated from the biomedical literature. Here, we present data, illustrating how InnateDB curation of the innate immunity interactome has greatly enhanced network and pathway annotation available for systems-level analysis and discuss the challenges that face such curation efforts. Significantly, we provide several lines of evidence that analysis of the innate immunity interactome has the potential to identify novel signalling, transcriptional and post-transcriptional regulators of innate immunity. Additionally, these analyses also provide insight into the cross-talk between innate immunity pathways and other biological processes, such as adaptive immunity, cancer and diabetes, and intriguingly, suggests links to other pathways, which as yet, have not been implicated in the innate immune response. Conclusions In summary, curation of the InnateDB interactome provides a wealth of information to enable systems-level analysis of innate immunity. PMID:20727158

    Sleeve gastrectomy is one of the most commonly performed procedures in obesity and metabolic operation with leakage and stenosis being serious complications. The management of these complications is challenging, with different operative options available. The aim of our study was to evaluate the incidence and management strategies of leakage and stenosis after sleeve gastrectomy at our institution and to compare our outcomes with those previously reported in the literature. We conducted a retrospective analysis of the medical records of 49 patients treated for leakage and/or stenosis after laparoscopic sleeve gastrectomy at our Centre of excellence for bariatric and metabolic operation, including 25 patients referred to our department from other hospitals. Outcomes were evaluated using descriptive statistics. Our study cohort consisted of 49 obese patients, 33 females (66%), with a mean ± standard deviation age of 50 ± 11 years, and body mass index at the time of laparoscopic sleeve gastrectomy, 51 ± 8 kg/m(2). Postsleeve gastrectomy leakage was identified in 27 patients (55%), stenosis in 13 (27%), and combined leakage and stenosis in 9 (18%). Leakage, stenosis, and combined leakage/stenosis were managed successfully by interventional methods in 85%, 15%, and 22% of cases, respectively. Conversion into another procedure provided a successful rescue operation for other patients. We had a 0% mortality rate. Most patients with leakage were managed successfully with interventional methods. The majority of patients with stenosis or both leakage and stenosis required rescue operation.

    Laparoscopic gastrectomy has emerged in recent years as an effective technique for the treatment of morbid obesity due to low mortality morbidity rates. Its complications include dehiscence suture line, and others such as splenic infarction. We discuss a case of splenic infarction after laparoscopic gastrectomy. 45 year old male with a BMI of 37.8 kg/m(2), diabetes-II for 15 years, the last five in treatment with insulin, a fasting blood glucose around 140mg/dl, HbA1c of 7.3mg/dl and microangiopathy diabetic nephropathy. The patient underwent a laparoscopic sleeve gastrectomy and he was discharged from hospital 48hours later. 1 month later he presented at the hospital for epigastric pain and fever up to 40° C. An intra abdominal abscess was detected and there was no leakage. The spleen was normal. He was treated with radiological drainage. 9 months later the patient consulted again due to epigastric pain in upper left quadrant, associated with low-grade fever. Thoraco-abdominal CT images compatible with splenic infarction. Currently patient remains asymptomatic one year after surgery. Laparoscopic sleeve gastrectomy is one of the most popular procedures of bariatric surgery. Less common complications include abscess and the splenic infarction. Usually patients are asymptomatic, but sometimes cause fever and pain. Initial treatment should be conservative. Only in selected cases, would splenectomy be indicated. Splenic infarction is usually an early complication, but we should keep it in mind as a long term complication for patients with persistent fever and abdominal pain after laparoscopic gastrectomy.

    Sleeve gastrectomy (SG), which, thus far, is showing good resolution of comorbidities and good weight loss, shows increasing popularity among bariatric surgeons. The aim of this study was to evaluate clinical outcome and the gastric emptying of solid foods, 24 months after SG. Fourteen morbidly obese patients, four males and ten females, median age 41 years (range 29-65), median body mass index (BMI) 49.46 kg/m(2) (range 41.14-55.63), who underwent SG for weight loss, were studied prospectively. Nine patients underwent gastric emptying studies, using radioisotopic technique before, 6 months and 24 months after the operation. The remaining five patients underwent gastric emptying studies, 6 months and 24 months after the operation. A significant reduction in patients' weight and BMI was evident at 6, 12 and 24 months postoperatively. In the nine patients who underwent gastric emptying studies pre-, 6 and 24 months postoperatively, the T-lag phase duration significantly decreased, following the SG, from 17.30 (range 15.50-20.90) min, to 12.50 (range 9.20-18.00) min at 6 months and 12.16 (range 10.90-20.00) min at 24 months postoperatively (P < 0.05). The gastric emptying half time (T1/2) accelerated significantly postoperatively from 86.50 (range 77.50-104.60) min, to 62.50 (range 46.30-80.00) min at 6 months and 60.80 (range 54.80-100.00) min at 24 months after SG (P < 0.05). The percentage of gastric emptying (%GE) increased significantly postoperatively, from 52 (range 43-58) % to 72 (range 57-97) % at 6 months and 74 (range 45-82) % at 24 months, following SG (P < 0.05). No differences in gastric emptying were observed, when values at 24 months were compared to those at 6 months postoperatively. When the whole group of 14 patients was studied, there were also no significant changes in T-lag, T1/2 and %GE between 6 and 24 months postoperatively. Our study indicates the constant effect of SG in the acceleration of gastric emptying of solids, which occurs faster

    Background and aim Obesity is a major risk factor for the onset of insulin resistance (IR), hyperinsulinemia and type 2 diabetes mellitus (T2DM) Evidence data has proven that beyond important weight loss bariatric surgery especially Roux-en-Y gastric bypass (RYGB) and bilio-pancreatic diversion (BPD) leads to significant early reduction of insulinemia and of IR calculated through the homeostatic model assessment (HOMA-IR), independently of fat mass decrease. Sleeve gastrectomy (SG) is now used as a sole weight loss operation with good results. Therefore, the aim of the present study was to investigate the early changes of fasting blood glucose, insulin and HOMA-IR in a group of morbidly obese (MO) patients i.e. at 7, 30 and 90 days after SG. Methods The study included 20 MO patients (7 male and 13 female) submitted to SG. Anthropometrical (weight, body mass index –BMI, percent excess BMI loss -%EBMIL) and biochemical (plasma glucose, insulin and calculated HOMA-IR ) evaluation were performed before and at 7, 30 and 90 days after SG. In addition, a second group of 10 normal weight healthy subjects with a BMI ranging form 19 kg/m2 to 23.14 kg/m2, matched for age and gender was investigated. Results Plasma glucose (p=0.018), insulin (p=0.004) and HOMA-IR (p=0.006) values were statistically different between the studied groups. After surgery, at every follow-up point, there were statistically different weight and BMI mean values relative to the operation day (p<0.003). BMI, decreased at 7 days (estimated reduction=2.79; 95% CI:[2.12;3.45]), at 30 days (estimated reduction=5.65; 95% CI:[3.57;7.73]) and at 90 days (estimated reduction=10.88; 95% CI:[7.35;14.41]) respectively after SG. We noted a tendency toward statistical significant change of mean insulin values at 7 days after surgery (corrected p=0.075), no statistical change at 30 days (corrected p=0.327) and a significant change at 90 days (corrected p=0.027) after SG as compared to baseline.

    Laparoscopic distal gastrectomy (LDG) is becoming the standard procedure for gastric cancer. However, supporting evidence thus far has been derived primarily from randomized control trials conducted by centers of excellence. In the present study we used the National Clinical Database (NCD) in Japan to prospectively accumulate data from diverse types of hospitals and examine whether LDG is a safe and valid standard procedure. From the NCD, 169 institutions were selected to form a cohort that was considered to be representative of Japan. From August 2014 to July 2015, 5288 patients who underwent LDG were registered prospectively, and clinical data were acquired through the NCD. To compare surgical outcomes between open distal gastrectomy (ODG) and LDG, we adjusted for confounding factors using propensity score matching, ultimately retrieving data from 1067 patients in each group. There were no significant differences in the number of in-hospital deaths in the ODG and LDG groups (3/1067 vs. 6/1067; P = 0.51) or in the number of reoperations (20/1067 vs. 29/1067; P = 0.19). However, the length of hospital stay was significantly shorter in the LDG. Although wound infection and dehiscence were more common in the ODG group, LDG was more often associated with grade B or higher pancreatic fistulas. The safety and minimal invasiveness of LDG were confirmed in the present Japanese nationwide survey. However, care must be taken to prevent the formation of pancreatic fistulas with LDG, and further improvements in surgical quality are warranted in this regard.

  11. How much does curation cost?

    PubMed

    Karp, Peter D

    2016-01-01

    NIH administrators have recently expressed concerns about the cost of curation for biological databases. However, they did not articulate the exact costs of curation. Here we calculate the cost of biocuration of articles for the EcoCyc database as $219 per article over a 5-year period. That cost is 6-15% of the cost of open-access publication fees for publishing biomedical articles, and we estimate that cost is 0.088% of the cost of the overall research project that generated the experimental results. Thus, curation costs are small in an absolute sense, and represent a miniscule fraction of the cost of the research. © The Author(s) 2016. Published by Oxford University Press.

    Objective: To describe the clinical characteristics, indications, technical procedures, and outcome of a consecutive series of laparoscopic distal pancreatic resections performed by the same surgical team. Summary Background Data: Laparoscopic distal pancreatic resection has increasingly been described as a feasible and safe procedure, although accompanied by a high rate of conversion and morbidity. Methods: A consecutive series of patients affected by solid and cystic tumors were selected prospectively to undergo laparoscopic distal pancreatectomy performed by the same surgical team. Clinical characteristics as well as diagnostic preoperative assessment and intra- and postoperative data were prospectively recorded. A follow-up of at least 3 months was available for all patients. Results: Fifty-eight patients underwent laparoscopic resection between May 1999 and November 2005. All procedures were successfully performed laparoscopically, and no patient required intraoperative blood transfusion. Splenic vessel preservation was possible in 84.4% of spleen-preserving procedures. There were no mortalities. The overall median hospital stay was 9 days, while it was 10.5 days for patients with postoperative pancreatic fistulae (27.5% of all cases). Follow-up was available for all patients. Conclusions: Our experience in 58 consecutive patients was characterized by the lack of conversions and by acceptable rates of postoperative pancreatic fistulae and morbidity. Laparoscopy proved especially beneficial in patients with postoperative complications as they had a relatively short hospital stay. Solid and cystic tumors of the distal pancreas represent a good indication for laparoscopic resection whenever possible. PMID:17592294

    In bioinformatics, we are familiar with the idea of curated data as a prerequisite for data integration. We neglect, often to our cost, the curation and cataloguing of the processes that we use to integrate and analyse our data. Programmatic access to services, for data and processes, means that compositions of services can be made that represent the in silico experiments or processes that bioinformaticians perform. Data integration through workflows depends on being able to know what services exist and where to find those services. The large number of services and the operations they perform, their arbitrary naming and lack of documentation, however, mean that they can be difficult to use. The workflows themselves are composite processes that could be pooled and reused but only if they too can be found and understood. Thus appropriate curation, including semantic mark-up, would enable processes to be found, maintained and consequently used more easily. This broader view on semantic annotation is vital for full data integration that is necessary for the modern scientific analyses in biology. This article will brief the community on the current state of the art and the current challenges for process curation, both within and without the Life Sciences.

    This review article summarizes knowledge about metachronous gastric cancer (MGC) occurring after curative endoscopic resection (ER) of early gastric cancer (EGC), treatment outcomes of patients who developed MGC, and efficacy of Helicobacter pylori eradication to prevent MGC. The incidence of MGC following curative ER increases over time and is higher than in patients undergoing gastrectomy. Increasing age and multifocal EGC are independent risk factors for developing MGC. An MGC following curative ER is usually a small (<20 mm) and differentiated intramucosal cancer. Most MGC lesions are found at an early stage on semiannual or annual surveillance endoscopy and are successfully treated by further ER, with excellent long-term outcomes. Eradication of H. pylori may reduce the risk of MGC following ER of EGC, but further prospective studies with long-term outcomes are required. Surveillance endoscopy following gastric ER should be continued indefinitely, due to the risk of MGC even after successful H. pylori eradication. Risk stratification and tailored endoscopic surveillance schedules need to be developed.

    Background Although general agreement exists on palliative surgery with intent of symptom palliation in advanced gastric cancer (AGC), the role of non-curative surgery for incurable, asymptomatic AGC is hotly debated. We aim to clarify the role of non-curative surgery in patients with incurable, asymptomatic AGC under the first-line chemotherapy. Methods A total of 737 patients with incurable, asymptomatic advanced gastric adenocarcinoma between January 2008 and May 2012 at the Sun Yat-sen University Cancer Center were retrospectively analyzed, comprising 414 patients with non-curative surgery plus first-line chemotherapy, and 323 patients with first-line chemotherapy only. The clinicopathologic data, survival, and prognosis were evaluated, with propensity score adjustment for selection bias. Results The median overall survival (OS) outcomes significantly favored non-curative surgery group over first-line chemotherapy only group in entire population (28.00 versus 10.37 months, P = 0.000), stage 4 patients (23.87 versus 10.37 months, P = 0.000), young patients (28.70 versus 10.37 months, P = 0.000) and elderly patients (23.07 versus 10.27 months, P = 0.031). The median OS advantages of non-curative surgery over first-line chemotherapy only were also maintained when the analyses were restricted to single organ metastasis (P = 0.001), distant lymph node metastasis (P = 0.002), peritoneal metastasis (P = 0.000), and multi-organ metastasis (P = 0.010). Significant OS advantages of non-curative surgery over chemotherapy only were confirmed solid by multivariate analyses before and after adjustment on propensity score (P = 0.000). Small subsets of patients with surgery of single metastatic lesion after previous curative gastrectomy, and with surgery of both primary and single metastatic sites showed sound median OS. Conclusions There is a role for non-curative surgery plus first-line chemotherapy for incurable, asymptomatic AGC, in

    The purpose of this study was to compare clinical features of vitamin B12 deficiency patients with a history of gastrectomy to those without a history of gastrectomy. Twenty-two patients with vitamin B12 deficiency were included. Patients' chief complaints, oral manifestations, blood examination results, and past medical histories were reviewed. Eleven patients had a history of gastrectomy and 11 did not. The chief complaint was glossodynia in all patients. No significant differences were observed between the two groups regarding age, sex, symptom duration, or plasma vitamin B12 level. Erythema and depapillation of the tongue were the most common findings, however less common among patients without a history of gastrectomy. Two patients with a history of gastrectomy and 5 patients without a history of gastrectomy had normal oral mucosa. Patients with a history of gastrectomy were more anemic. Oral symptoms of the majority of patients responded to antifungals and vitamin B12 replacement. The suggested etiologies for vitamin B12 deficiency in the patients without a history of gastrectomy were gastritis, medications, diet, autoimmunity, and early gastric cancer. Vitamin B12 deficiency and its associated etiological factors should be considered in patients with glossodynia, even those whose oral mucosa appears normal and who lack a history of gastrectomy.

    To present 5-year results of sleeve gastrectomy (SG) with transit bipartition (TB) as a metabolic intervention for obesity. Recent data suggest that high glycemic index foods may lead to a hormonally hyperactive proximal gut and a hypoactivate distal gut, which are linked to metabolic syndrome. TB was designed to counterbalance these effects. A total of 1020 obese patients with body mass index (BMI) ranging from 33 to 72 Kg/m underwent SG and TB (SG + TB). TB creates a gastroileal anastomosis in the antrum after the SG; nutrient transit is maintained in the duodenum, avoiding blind loops and minimizing malabsorption. The stomach retains 2 outflow pathways. A lateral enteroanastomosis connects both segments at 80 cm proximal to the cecum. Adequate follow-up data were collected in 59.1% of patients from 4 months to 5 years. The average percent of excess BMI loss was 91%, 94%, 85%, 78%, and 74% in the first, second, third, fourth, and fifth year, respectively. Patients experienced early satiety and major improvement in presurgical comorbidities, including diabetes (86% in remission), following surgery. Two deaths occurred (0.2%). Other surgical complications occurred in 6% of patients. Signs of malabsorption were rare. SG + TB is a simple procedure that results in rapid weight loss and remission or major improvement of comorbidities. Strictly aiming at physiological correction, TB avoids prostheses, narrow anastomoses, excluded segments, and malabsorption. Weight and comorbidities are much improved. Diabetes is improved without duodenal exclusion. TB is an excellent complement to an SG.

    Laparoscopic sleeve gastrectomy is known to be associated with a risk of gastric staple line leak. We report on our experience with endoscopic stenting of the anomalous leaking tract. Three cases of post sleeve gastric leak confirmed by computed tomography scan were treated by endoscopic stenting of their leak with a plastic endoprosthesis under fluoroscopic and endoscopic guidance. Endoscopic stenting by means of biliary or pancreatic endoprosthesis was successful in the three patients. The median number of endoscopy procedures per patient was 1.3. Stents were extracted 6 to 10 weeks after their placement. Neither morbidity nor recurrence was noticed on follow-up. Endoscopic stenting of gastric staple line leak following sleeve gastrectomy proved to be an efficacious technique for leak healing.

    Sleeve gastrectomy (SG) is a restrictive bariatric surgery technique that was first used as part of restrictive horizontal gastrectomy in the original Scopinaro type biliopancreatic diversion. Its good results as a single technique have led to a rise in its use, and it is currently the second most performed technique worldwide. SG achieves clearly better results than other restrictive techniques and is comparable in some aspects to the Roux-en-Y gastric bypass, the current gold standard in bariatric surgery. These benefits have been associated with different pathophysiologic mechanisms unrelated to weight loss such as increased gastric emptying and intestinal transit, and activation of hormonal mechanisms such as increased GLP-1 hormone and decreased ghrelin. The aim of this review was to highlight the salient aspects of SG regarding its historical evolution, pathophysiologic mechanisms, main results, clinical applications and perioperative complications.

    This study aims to analyze the scientific production about patients with gastric cancer submitted to gastrectomy and describe important aspects of nursing guidelines for these patients. An integrative review was carried out using Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE) databases; twenty two articles were analyzed. Retrospective cross-sectional studies were the most frequent. The scientific production of nursing is numerically small in relation to the medical area. The results show that approaches related to pre and post-operative in gastrectomy for gastric cancer resection subsidize the knowledge of issues essential for nurses to promote efficient intervention for the recovery of such patients. There is still the need for further research on the practice of nursing in the guidelines of this kind of surgery.

    Over the last 15 years, obesity surgery has developed tremendously. The two most frequently practiced procedures are the adjustable gastric ring and gastric by-pass. A new intervention has recently appeared: the sleeve gastrectomy, an essentially restrictive intervention consisting of a vertical gastrectomy including the entire greater curvature of the stomach while leaving in place an approximately 100-ml gastric tube along the lesser curvature. This intervention was initially proposed as the first part of a duodenal switch in patients whose body mass index was greater than 60 kg/m2. Since then, these indications have developed and this intervention now enjoys a certain fervor on the part of bariatric surgery teams. The objective of this mini-review is to detail the technical aspects of this procedure, its morbidity and mortality, and the long-term results, although there are currently few teams with more than 3 years of experience.

    A 67-year-old man was admitted to our hospital in May 2006 because of gait disturbance, delirium and myoclonus along with dermatitis and diarrhea. Those symptoms became worse in 3 months. He had undergone a gastrectomy, including a fundectomy and jejunal pouch interposition, for early gastric cancer at the age of 65 years. He had no habit of drinking alcohol or unbalanced diet. The triad of typical dermatitis, delirium, and diarrhea led to a diagnosis of pellagra, and all the symptoms disappeared after intravenous administration of nicotinate and vitamins. With a gastrectomy, fundectomy performed with jejunal pouch interposition has been regarded as a superior method for postoperative nutrition, but may cause vitamin deficiency. Thus, vitamin deficiency must be considered as a potential cause in neurologic patients who underwent surgical treatment for disorders of digestive tract, regardless of the procedure utilized.

    Distal radioulnar joint (DRUJ) instability is a common clinical condition but a frequently missed diagnosis. Both surgical and nonsurgical treatments are possible for chronic cases of DRUJ instability. Nonsurgical treatment can be considered as the primary therapy in less active patients, while surgery should be considered to recover bone and ligament injuries if nonsurgical treatment fails to restore forearm stability and function. The appropriate choice of treatment depends on the individual patient and specific derangement of the DRUJ PMID:26328241

    Distal radioulnar joint is a trochoid joint relatively new in evolution. Along with proximal radioulnar joint, forearm bones and interosseous membrane, it allows pronosupination and load transmission across the wrist. Injuries around distal radioulnar joint are not uncommon, and are usually associated with distal radius fractures,fractures of the ulnar styloid and with the eponymous Galeazzi or Essex_Lopresti fractures. The injury can be purely involving the soft tissue especially the triangular fibrocartilage or the radioulnar ligaments. The patients usually present with ulnar sided wrist pain, features of instability, or restriction of rotation. Difficulty in carrying loads in the hand is a major constraint for these patients. Thorough clinical examination to localize point of tenderness and appropriate provocative tests help in diagnosis. Radiology and MRI are extremely useful, while arthroscopy is the gold standard for evaluation. The treatment protocols are continuously evolving and range from conservative, arthroscopic to open surgical methods. Isolated dislocation are uncommon. Basal fractures of the ulnar styloid tend to make the joint unstable and may require operative intervention. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Prosthetic replacement in arthritis is gaining acceptance in the management of arthritis.

    Sideropenic anemia after a gastrectomy is a frequent complication. The aim of the present study was to evaluate the role of different factors, such as sex, age, atrophic chronic gastritis, Helicobacter pylori infection and iron malabsorption, in iron deficiency after surgery for gastric cancer. Thirty-seven patients who underwent subtotal gastrectomy for carcinoma of the stomach were prospectively studied following a specific three-year protocol. Iron deficiency was evaluated by hemochromocytometric analysis and serum iron-ferritin level assays. Of the different variables analyzed, atrophic chronic gastritis was associated with a lower mean serum iron level, in particular two years after surgery (65mg/dL vs. 103 mg/dL in subjects without gastritis, P<0.01); a correlation between Helicobacter pylori infection of the gastric stump and lower mean serum ferritin level was also found (25+/-6.3 mg/dL vs. 53+/-0.4 mg/dL, P<0.05). On the contrary, no association was observed with the other factors that were evaluated. Among the factors involved in iron deficiency after gastrectomy for cancer of the stomach, atrophic gastritis seems to be the most important, although Helicobacter pylori infection of the gastric stump also seems to play an important role.

    Olfactory abilities of the patients are known to be altered by eating and metabolic disorders, including obesity. There are only a number of studies investigating the effect of obesity on olfaction, and there is limited data on the changes in olfactory abilities of morbidly obese patients after surgical treatment. Here we investigated the changes in olfactory abilities of 54 morbidly obese patients (M/F, 22/32; age range 19-57 years; body mass index (BMI) range 30.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. A laparoscopic sleeve gastrectomy was performed by the same surgeon using five-port technique. Olfactory abilities were tested preoperatively and 1, 3, and 6 months after the surgery using a standardized Sniffin' Sticks Extended Test kit. Analyses of variance indicated statistically significant improvement in T, D, and I scores of morbidly obese patients within time factors (preoperative vs. 1, 3, and 6 months; 1 vs. 3 and 6 months; and 3 vs. 6 months; p < 0.001 for all). There was a statistically significant improvement in overall TDI scores with an increase from 25 to 41 during the 6 months follow-up period (p < 0.001 for all). Here, for the first time in literature, we were able to show the significant improvement in olfactory abilities of morbidly obese patients after laparoscopic sleeve gastrectomy.

    Introduction Laparoscopic sleeve gastrectomy is a procedure frequently chosen by patients and surgeons that carries the risk of serious complications that are difficult to treat. Aim To describe the operations performed by us, considering complications and their management. Material and methods We performed 565 laparoscopic sleeve gastrectomies. Standard surgical technique was used. A 34 Fr calibration tube was used. An additional reinforcing suture was applied over the staple line. Results There was no need for conversion. In 7.79% of patients, infarcts of the posterior pole of the spleen were observed, whereas 8 patients (1.42%) developed gastric fistulas in the His angle region. In 3 cases, it led to development of an abscess in the posterior splenic pole region and 2 of these developed secondary gastric fistulas of typical location. In total, there were 5 deaths among the patients who had been operated on – 3 due to septic complications in the course of fistula, 1 due to encephalopathy and 1 as a result of myocardial infarction. Conclusions Sleeve gastrectomy is an effective and safe method of obesity treatment. The causes of the most severe complication – gastric fistula – cannot be established unequivocally. Infarcts of the posterior pole of the spleen, as a potential cause of fistulas, deserve particular attention. In our opinion, primary closure of the fistula by suturing is an inappropriate method of management, whereas the best results are obtained with temporary gastrointestinal tract prosthesis.

    This report is concerned with series of patients with advanced gastric cancer in whom transverse colon segment interposition, namely an end-to-end esophagocolostomy plus coloduodenostomy (Type-I) from 1965 to 1970 and an end-to-side esophagocolostomy plus coloduodenostomy (Type-II) from 1986 to 1996 were performed after total gastrectomy. Fifty-two patients with Type-I reconstruction and 133 patients with Type-II reconstruction after total gastrectomy were studied. Postoperative nutritional condition and complications were investigated and changes in the size and high amplitude propagated contractions of the interposed colon were measured. The interposed transverse colon segment which was placed in an iso-peristaltic fashion between esophagus and duodenum dilated gradually and capable of taking a reasonable quantity of food at one time. The nutritional status was good especially in long-term survivors. Complications such as reflux esophagitis (12.0% after Type-I and zero% in Type-II fashion) have occurred. The iodinated Triolein 131I absorption test has shown 92.4% absorption rate of the material, a value comparable to that of patients subjected to Billroth-I type gastric resection. In conclusion, pedicle transplantation of a segment of the transverse colon, especially Type-II fashion, is feasible and useful to use in patients undergoing total gastrectomy.

    Absorption of radiolabeled cobalamin in baboons was assessed by whole body counting. Retention of biliary cobalamin and an aqueous solution of cyanocobalamin was measured in normal baboons and in baboons after total gastrectomy by using /sup 57/Co-labeled biliary cobalamin and /sup 58/C0-cyanocobalamin, with and without baboon gastric juice containing intrinsic factor. Radiolabeled biliary cobalamin was obtained by intravenous injection of /sup 57/Co-cyanocobalamin in baboons and collection of bile through a cannula placed in the common bile duct. Cobalamin absorption was not completely abolished by gastrectomy and biliary cobalamin was better retained than cyanocobalamin; intrinsic factor enhanced absorption of both forms. After gastrectomy there was steady depletion of liver and serum cobalamin levels, which ceased after a new equilibrium was reached between a progressively diminishing cobalamin loss and the impaired but significant residual level of absorption. These studies in the nonhuman primate provide further information concerning the enterohepatic circulation of cobalamin and suggest that the form of cobalamin in bile may be more readily absorbed than is cyanocobalamin or that bile itself may have an enhancing effect on cobalamin absorption. The data also suggest that physiologically significant amounts of cobalamin may be absorbed in the absence of a gastric source of intrinsic factor.

    INTEREST OF WORK: The longitudinal or "sleeve" gastrectomy was recently introduced into the therapeutic arsenal of the bariatric surgeon. It is a restrictive procedure that reduces stomach capacity by 75%. We present here a preliminary experience with four patients. Four patients with super super obesity (body mass index (BMI)>60 kg/m2) underwent longitudinal or "sleeve" gastrectomy. Their average preoperative weight was 173 kg (range: 147-190 kg) and mean BMI 65 kg/m2 (range: 61-67 kg/m2). The average post-operative follow-up was 6 months (range: 2-12 months). Average weight loss at 6 months was 40 kg (range: 20-60 kg) and average decrease in BMI at 6 months 16.3 kg/m2 (range: 6-23 kg/m2). We noted a postsurgical complication in only one patient (subdiaphragmatic abscess treated with drainage). These preliminary results suggest that the sleeve gastrectomy is associated with few perioperative complications and offers rapidly effective treatment for super super morbid obesity. Long-term results require further investigation.

    Many meta-analyses have confirmed the technical feasibility and favorable short-term surgical outcomes of laparoscopic gastrectomy (LG) for gastric cancer patients, but the long-term survival outcome of LG remains controversial compared with open gastrectomy (OG). This study aimed to compare the 5-year overall survival (OS), recurrence, and gastric cancer-related death of LG with OG among gastric cancer patients. PubMed was searched to February 2014. The resectable gastric cancer patients who underwent curative LG or OG were eligible. The studies that compared 5-year OS, recurrence, or gastric cancer-related death in the LG and OG groups were included. A meta-analysis, meta-regression, sensitivity analysis, subgroup analysis, and stage-specific analysis were performed to estimate the survival outcome between the two groups and identify the potential confounders. Quality assessment was based on a tailored comparability scoring system. Twenty-three studies with 7336 patients were included. The score of comparability between two groups and the extent of lymphadenectomy were two independent confounders. Based on the well-balanced studies, the 5-year OS (OR = 1.07, 95% CI 0.90-1.28, P = 0.45), recurrence (OR = 0.83, 95% CI 0.68-1.02, P = 0.08), and gastric cancer-related death (OR = 0.86, 95% CI 0.65-1.13, P = 0.28) rates were comparable in LG and OG. Several subsets such as the publication year, study region, sample size, gastrectomy pattern, extent of lymphadenectomy, number of nodes harvested, and proportion of T1-2 or N0-1 did not influence the estimates, if they were well balanced. Particularly, the stage-specific estimates obtained comparable results between the two groups. Randomized controlled trials comparing LG with OG remain sparse to assess their long-term survival outcomes. The major contributions of this systematic review compared with other meta-analyses are a comprehensive collection of available long-term survival outcomes within

    Abstract The risk factors associated with postoperative pulmonary complications (PPCs) following laparoscopic gastrectomy have not been well studied. We sought to identify the risk factors for PPCs following gastric cancer surgery. A retrospective analysis was performed on all gastric cancer patients in a prospective database who underwent a laparoscopic gastrectomy from 2004 to 2014. The potential risk factors for PPCs were evaluated. PPCs occurred in 6.8% (83/1205) of patients and included pneumonia in 56 (67.5%) patients, pleural effusion in 26 (31.3%) patients, and pulmonary embolism in 1 (1.2%) patient. The multivariate analysis identified the following significant risk factors for PPCs: advanced age (odds ratio [OR] = 1.043, 95% confidence interval [CI] = 1.021%, 1.066%), chronic obstructive pulmonary disease (COPD) (OR = 17.788, 95% CI = 2.618%, 120.838%), total gastrectomy (OR = 2.781, 95% CI = 1.726%, 4.480%), time to first diet (OR = 1.175, 95% CI = 1.060%, 1.302%), and postoperative hospital stay (OR = 1.015, 95% CI = 1.002%, 1.028%). The risk factors for pneumonia included advanced age (OR = 1.036, 95% CI = 1.010%, 1.063%), total gastrectomy (OR = 3.420, 95% CI = 1.960%, 5.969%), and time to first diet (OR = 1.207, 95% CI = 1.703%, 1.358%). Only pancreatectomy was a risk factor for pleural effusion (OR = 9.082, 95% CI = 2.412%, 34.206%). The frequency of PPCs in patients with gastric cancer who underwent laparoscopic surgery was relatively high. Patients with cardiac and pulmonary comorbidities and those who undergo total gastrectomy and combined resection should be considered at high risk. PMID:27512884

    Curation of Mars samples includes both samples that are returned to Earth, and samples that are collected, examined, and archived on Mars. Both kinds of curation operations will require careful planning to ensure that the samples are not contaminated by the instruments that are used to collect and contain them. In both cases, sample examination and subdivision must take place in an environment that is organically, inorganically, and biologically clean. Some samples will need to be prepared for analysis under ultra-clean or cryogenic conditions. Inorganic and biological cleanliness are achievable separately by cleanroom and biosafety lab techniques. Organic cleanliness to the <50 ng/sq cm level requires material control and sorbent removal - techniques being applied in our Class 10 cleanrooms and sample processing gloveboxes.

Both kinds of curation operations will require careful planning to ensure that the samples are not contaminated by the instruments that are used to collect and contain them. In both cases, sample examination and subdivision must take place in an environment that is organically, inorganically, and biologically clean. Some samples will need to be prepared for analysis under ultra-clean or cryogenic conditions. Inorganic and biological cleanliness are achievable separately by cleanroom and biosafety lab techniques. Organic cleanliness to the <50 ng/sq cm level requires material control and sorbent removal - techniques being applied in our Class 10 cleanrooms and sample processing gloveboxes.

    Obesity and abdominal shape morphometric features have been thought to be independent risk factors for surgical outcomes after gastrectomy.A total of 113 patients undergoing surgery for primary gastric adenocarcinoma from June 2011 to January 2015 were retrospectively included. Body mass index, visceral fatty area, anterior-posterior abdominal and transverse diameters and depth ratio at levels of the umbilicus, the gastroesophageal junction and the root of the celiac artery were measured or calculated. Patients were grouped according to body mass index (<25.0 kg/m2or ≥25.0 kg/m2) or median value of these parameters. Surgical outcomes including postoperative complications, total and metastatic lymph node numbers and their ratio were compared.There was a significant association between body mass index and abdominal shape indexes. Body mass index and abdominal shape indexes showed no statistical significance on development of complications. But, lymph node numbers and their ratio were negatively affected by depth ratio at the root of the celiac artery.Our findings showed that gastrectomy with curative intent can be performed safely in patients with higher body mass index and abdominal shape indexes. Therefore, there is no need to perform any change in surgical strategy according to these measurements and calculations.

    Background Minimally invasive surgery, including laparoscopic and robotic gastrectomy, has become more popular in the treatment of gastric cancer. However, few studies have compared the learning curves between laparoscopic and robotic gastrectomy for gastric cancer. Methods Data were prospectively collected between July 2008 and Aug 2014. A total of 145 patients underwent minimally invasive gastrectomy for gastric cancer by a single surgeon, including 73 laparoscopic and 72 robotic gastrectomies. The clinicopathologic characteristics, operative outcomes and learning curves were compared between the two groups. Results Compared with the laparoscopic group, the robotic group was associated with less blood loss and longer operative time. After the surgeon learning curves were overcome for each technique, the operative outcomes became similar between the two groups except longer operative time in the robotic group. After accumulating more cases of robotic gastrectomy, the operative time in the laparoscopic group decreased dramatically. Conclusions After overcoming the learning curves, the operative outcomes became similar between laparoscopic and robotic gastrectomy. The experience of robotic gastrectomy could affect the learning process of laparoscopic gastrectomy. PMID:25360767

    It was the aim of this study to develop a methodology for dissection in laparoscopic distal gastrectomy with D2 lymphadenectomy (D2 LDG) for gastric cancer. One-hundred and thirty-two patients with distal gastric cancer underwent D2 LDG with a novel sequence of lymph node dissection between August 2004 and June 2008. Live anatomy in each step was observed simultaneously to ensure and confirm the newly developed methodology. Dissections in LDG were standardized as sequential steps: Dividing the gastrocolic ligament and getting access to the prepancreatic space--lymph node dissection in the lower left area--lymph node dissection in the lower right area--lymph node dissection in the upper right area--lymph nodes dissection centrally--lymph node dissection between liver and stomach. All dissections were successfully performed in peripancreatic spaces and their extensions. Gastric vessels were located by special landmarks, traced along vascular trunks and bifurcations, and identified by fine dissection technique in vaginavasorum. Sequential dissection around the pancreas was an effective method for D2 LDG. It was ensured by anatomical knowledge in each step: Vessels and fascial spaces around a central landmark, the pancreas.

    Purpose The purpose of this study is to suggest a treatment strategy for stage IV gastric cancer by investigating the behavioral difference between initially and recurrent metastatic disease. Methods We reviewed the medical records of the patients who underwent chemotherapy alone for metastatic gastric cancer between January 2006 and September 2013. Patients were divided into those who underwent chemotherapy for metastatic disease since initial diagnosis (IM group) and for metastatic recurrence after curative surgery (RM group). Survival and causes of death were compared between the 2 groups, and significant prognostic factors were also investigated. Results A total of 170 patients were enrolled in this study. Of these patients, 104 were included in the IM group and 66 in the RM group. Overall survival of the IM group did not differ from that of RM (P = 0.569). In the comparison of the causes of death, the IM group had a greater tendency to die from bleeding (P = 0.054) and pneumonia (P = 0.055). In multivariate analysis, bone metastasis (P < 0.001; HR = 2.847), carcinoma peritonei (P = 0.047; HR = 1.766), and the frequency of chemotherapy (P < 0.001; HR = 0.777) were significantly associated with overall survival of IM group. Conclusion Disease-burden mainly contributes to the prognosis of metastatic gastric cancer, although noncurative gastrectomy may be helpful in reducing the mortality of initially metastatic disease. Therefore, disease-burden should be also prioritized in determining the treatment strategies for stage IV gastric cancer. PMID:28090502

    Delayed gastric emptying (DGE) is one of the most troublesome complications after subtotal gastrectomy for gastric cancer. We evaluated operative and perioperative variables to assess for independent risk factors of DGE caused by anastomosis edema. The study retrospectively reviewed clinical data of 382 consecutive patients who underwent subtotal gastrectomy for gastric cancer between 2009 and 2011 at a single institution. Delayed gastric emptying had occurred in twelve patients (3.1%). Univariate analysis revealed high body mass index (>25kg/m2), open gastrectomy, and Billroth II or Roux-en Y reconstructions to be significant factors for delayed gastric emptying. Multivariate analysis identified high body mass index and open gastrectomy as predictors of delayed gastric emptying. To avoid delayed gastric emptying, surgeons should take care in creating the gastrointestinal anastomosis, particularly in patients with high BMI or in cases of open gastrectomy.

    Objectives Overlap between the distal tibia and fibula has always been quoted to be positive. If the value is not positive then an injury to the syndesmosis is thought to exist. Our null hypothesis is that it is a normal variant in the adult population. Methods We looked at axial CT scans of the ankle in 325 patients for the presence of overlap between the distal tibia and fibula. Where we thought this was possible we reconstructed the images to represent a plain film radiograph which we were able to rotate and view in multiple planes to confirm the assessment. Results The scans were taken for reasons other than pathology of the ankle. We found there was no overlap in four patients. These patients were then questioned about previous injury, trauma, surgery or pain, in order to exclude underlying pathology. Conclusion We concluded that no overlap between the tibia and fibula may exist in the population, albeit in a very small proportion. PMID:23610666

    The placement of a gastric band (GB) prior to a sleeve gastrectomy (LSG) would increase postoperative complications, whether it is withdrawn or not at the time of the LSG. The purpose of this retrospective study was to evaluate and compare postoperative morbidity and outcome weight for simultaneous GB removal (RGB) and LSG (the RGB + LSG group) and front-line LSG only (the LSG group) after unsuccessful GB. From May 2005 to May 2009, 305 patients underwent first- or second-line LSG at Amiens University Hospital. The primary endpoint was the postoperative complication rate (according to the Clavien classification) in the RGB + LSG and LSG groups. The secondary endpoints were intra-operative data, postoperative data, and weight loss over a period of 2 years (body mass index, percentage of excess weight loss, and percentage of excess body mass index (BMI) loss). Univariate and multivariate propensity score analyses were used to search for independent risk factors for postoperative complications. The RGB + LSG group (n = 46) had a mean age of 42 and a mean BMI of 44 kg/m(2). The indication for surgery was renewed weight gain or insufficient weight loss in 68 % of these cases. The LSG group (n = 259) had a mean age of 41 and a mean BMI of 49.2 kg/m(2). All procedures were performed laparoscopically. The complication rate was 8.6 % in the RGB + LSG group and 8 % in the SG group (p = 0.42). The fistula rates in the two groups were 4.3 and 3.4 %, respectively (p = 0.56), and the mean BMI at 2 years was 33.4 kg/m(2) (RGB + LSG group) and 34.4 kg/m(2), respectively (p = 0.83). The operating time for LSG (after subtracting the time associated with RGB for a combined procedure) averaged 107 min, whereas the operating time for front-line LSG was 89 min (p = 0.011). The propensity score analysis failed to find independent risk factors for postoperative complications. The performance of RGB + LSG is feasible and does not increase the postoperative

    A 5-month-old male infant presented with weak cry, decreased body movements, tightness of whole body since birth, and one episode of generalized seizure on day 4 of life. He was born at term by elective caesarian section performed for breech presentation. The child had failure to thrive, contractures at elbow and knee joints, hypertonia, microcephaly, small mouth, retrognathia, and camptodactyly. There was global developmental delay. Abdominal examination revealed umbilical and bilateral inguinal hernia. Visual evoked response and brainstem evoked response audiometry were abnormal. Nerve conduction velocity was normal. Magnetic resonance imaging of brain revealed paucity of white matter in bilateral cerebral hemispheres with cerebellar and brain stem atrophy. The differential diagnoses considered in the index patient were distal arthrogryposis (DA) syndrome, cerebroculofacioskeletal syndrome, and Pena Shokier syndrome. The index patient most likely represents a variant of DA: Sheldon Hall syndrome. PMID:20300297

    To investigate whether addition of tumor size improves the prognostic accuracy of the UICC 7th TNM staging system in gastric cancer patients who underwent radical surgery (R0 resection). The clinical and pathological data and postoperative 5-year survival rate of 507 patients with gastric cancer who underwent radical surgery (R0 resection) in our department from January 2004 to June 2006 were evaluated retrospectively. The prognostic accuracy of conventional UICC 7th TNM staging was compared with that of UICC 7th TNM staging plus tumor size. The ability of tumor size to improve the 95% confidence interval (CI) of postoperative 5-year survival rate in gastric cancer patients was assessed. Of the 507 patients, 470 (92.7%) were followed up. The five-year survival rate of these patients was 50.4%. The survival rates of patients with pT1, pT2, pT3, and pT4 stage tumors were 89.3%, 72.4%, 36.9%, and 23.7%, respectively (P < 0.05), and the survival rates of patients with pN0, pN1, pN2, and pN3 stage tumors were 75.2%, 68.8%, 46.7%, and 21.3% (P < 0.05). Depth of invasion, lymph node metastasis stage, metastatic lymph node ratio (MLR), lymphatic invasion and tumor size were independent predictors of patient prognosis. The accuracy of UICC 7th TNM staging in predicting 5-year survival was 75.4% and the accuracy of tumor size plus the UICC 7th TNM staging was 77.9% (P < 0.05). This combination improved the 95% CI of postoperative 5-year survival rate in gastric cancer patients. Tumor size can improve the accuracy of UICC 7th TNM staging in predicting survival in gastric cancer patients following radical surgery (R0 resection). Tumor size is likely to be another important indicator in future UICC-TNM staging systems for gastric cancer patients. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

    OBJECTIVE: The authors used prolamine (Ethibloc, Ethicon GmBH, Norderstedt, Germany) for segmental obstruction of the pancreatic duct to prevent pancreatic fistula development after distal pancreatectomy combined with total gastrectomy for gastric malignancies. SUMMARY BACKGROUND DATA: Although the initial clinical application of prolamine was pancreatic duct obstruction for patients with pancreatitis and undergoing pancreatic transplantation and pancreaticoduodenectomy for pancreatic cancer, there are no reports on prevention of pancreatic fistula formation after distal pancreatectomy. METHODS: Prolamine (0.2 mL) was injected into the distal segment of the main duct in the remaining pancreata of 51 patients. Small pancreatic ducts on the cut surface, from which prolamine extravasates, were closed by ligation, the main duct was ligated doubly, and the transected pancreatic margin was closed 15 minutes after phenylpropanolamine hydrochloride injection. RESULTS: No patient developed a pancreatic fistula or the complication of arterial bleeding due to prolonged infection. CONCLUSION: Segmental obstruction of the pancreatic duct with prolamine is useful for preventing pancreatic fistula development after distal pancreatectomy. Images Figure 2. Figure 3. Figure 4.

    Radical gastrectomy with an adequate lymphadenectomy is the main procedure which makes it possible to cure patients with resectable gastric cancer (GC). A number of randomized controlled trials and meta-analysis provide phase III evidence that laparoscopic gastrectomy is technically safe and that it yields better short-term outcomes than conventional open gastrectomy for early-stage GC. While laparoscopic gastrectomy has become standard therapy for early-stage GC, especially in Asian countries such as Japan and South Korea, the use of minimally invasive techniques is still controversial for the treatment of more advanced tumours, principally due to existing concerns about its oncological adequacy and capacity to carry out an adequately extended lymphadenectomy. Some intrinsic drawbacks of the conventional laparoscopic technique have prevented the worldwide spread of laparoscopic gastrectomy for cancer and, despite technological advances in recent year, it remains a technically challenging procedure. The introduction of robotic surgery over the last ten years has implied a notable mutation of certain minimally invasive procedures, making it possible to overcome some limitations of the traditional laparoscopic technique. Robot-assisted gastric resection with D2 lymph node dissection has been shown to be safe and feasible in prospective and retrospective studies. However, to date there are no high quality comparative studies investigating the advantages of a robotic approach to GC over traditional laparoscopic and open gastrectomy. On the basis of the literature review here presented, robot-assisted surgery seems to fulfill oncologic criteria for D2 dissection and has a comparable oncologic outcome to traditional laparoscopic and open procedure. Robot-assisted gastrectomy was associated with the trend toward a shorter hospital stay with a comparable morbidity of conventional laparoscopic and open gastrectomy, but randomized clinical trials and longer follow-ups are

    Laparoscopy-assisted distal gastrectomy (LADG) for stomach cancer is increasingly performed in Japan and Korea. However, the procedure still is considered to be complicated, and the optimal education system for trainees has not been established to date. The authors organized a 1-day professional training course termed the LADG Basic Lab Course for LADG beginners. The participants were required to apply as a team of two surgeons and two operating nurses. The training course consisted of lectures and a live porcine lab emphasizing use of the ultrasonically activated device and the flexible laparoscope as well as team cooperation. The quality and effectiveness of the course were evaluated 6-10 months (mean, 8.2 +/- 2.2 months) after the course using a survey form sent to a representative surgeon of each institution. From May 2007 to July 2008, a total of 80 colleagues (47 surgeons and 33 nurses) from 20 different centers in Japan participated in the training course. These surgeons represented 12.4 +/- 6.2 postgraduate years of education and had performed 2.7 +/- 4.9 LADGs before taking the course. In the follow-up evaluation, 12 institutions (60%) completed the survey forms. The mean operation time was reduced for eight respondents (66.7%). The number of LADGs performed per month increased in 50% of the respondents' institutions. The degree of lymph node dissection in LADG was extended for 66.7% of the respondents. The respondents answered that 100% of the first operators showed improvement in skills, as did 59.5% of the scope operators and 59.5% of the nurses. The training course was an effective means of introducing LADG to each institution. Training courses emphasizing explanations of key devices and teamwork may be effective for the introduction of advanced laparoscopic surgeries.

    Objective To describe a case of Wernicke’s encephalopathy after laparoscopic sleeve gastrectomy. Setting Emergency Department and gastrointestinal surgery department. Case report A 20-year-old man class III obesity (BMI 50.17 kg/m2) underwent laparoscopic sleeve gastrectomy with uneventful recovery. Five weeks after surgery he was admitted in the Emergency Department because of persistent vomiting and dysphagia to solids. Esophagogastroduodenal transit and upper gastrointestinal endoscopy were requested but no relevant findings were shown. Laboratory analyses showed vitamin B1 12.2 ng/mL and 48 h following admission the patient experienced generalized weakness, sialorrhea and restrictions of actions such as reading a book. Neurological evaluation found confusion, motor ataxia, diplopy and nystagmus. A brain magnetic resonance was normal. According to low level of vitamin B1 and symptoms found in the patient a presumed diagnosis of Wernicke encephalopathy was made and parenteral thiamine 100 mg/day was started. The patient was discharged asymptomatic with oral intake of vitamin B1 600 mg per day. Conclusion Nutritional deficiencies after restrictive procedures are uncommon but easily preventable and can result in life threatening. With the upswing of bariatric surgery, surgeons and emergency physicians should be able to diagnose and treat those complications. Prophylactic thiamine should be administered to patients with predisposing factors. PMID:26826934

    Esophago-gastric necrosis is a surgical emergency associated with high morbidity and mortality. We report a laparoscopic transhiatal esophago-gastrectomy performed on a 43-year-old male, presenting two hours after hydrochloric acid ingestion. A gastroscopy showed several oral mucosal ulcers, a significant edema of the pharynx and larynx, a necrosis of the middle and lower esophagus and of the gastric fundus and antrum. A conservative strategy with intensive care observation was initially followed. After a change of clinical signs, chest-abdominal computed tomography was realized and a pneumoperitoneum with free fluid in the left subphrenic space and bilateral pleural effusions was in evidence. A laparoscopic exploration was proposed to the patient, and confirmed the presence of free peritoneal fluid and necrosis with perforation of the upper part of the stomach. A laparoscopic total gastrectomy with subtotal esophagectomy was performed; the procedure finished with an esophagostomy on the left side of the neck and a laparoscopic feeding jejunostomy (video). Total operative time was 235 minutes. After six months a digestive reconstruction with esophagocoloplasty by laparotomy and cervicotomy was easily realized thanks to the advantages (few adhesions, bloodless, and simple colic mobilization) of the previous minimally invasive surgery.

    The prognosis after a curative resection for gastric cancer is modified by the lymph node involvement, while the prognostic significance of a microscopically-positive resection margin is debated. We systematically reviewed the literature from 1998 to 2013 to describe the role of surgery in the management of gastric cancer with a R1 after gastrectomy. The research was systematically performed on Pubmed, EMbase, Cochrane Library, CILEA Archive, BMJ Clinical Evidence and Up ToDate databases. Twelve studies were included in this review, for a total of 15,008 patients. The results reported in literature are inconsistent and the impact of surgical and oncological therapies is unknown. Intraoperative frozen sections should be performed to achieve a negative margin with intraoperative re-excision. A surgical re-excision of an R1 resection should be considered for patients with fewer than three disease-positive nodes because survival is more likely to be governed by positive margins than by nodal status.

    Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Several methods have been proposed for repairing a distal penile erosion. We present our preliminary experience in "Distal corporoplasty" technique. We enrolled 18 consecutive patients whose underwent a distal corporoplasty with simultaneous reimplantation of an "AMS 700 inflatable penile prosthesis (LGX)" from January 2013 to November 2015 at our hospital. All procedures were performed by a single surgical team. Intraoperative and postoperative complications have been classified and reported according to Satava6 and Clavien-Dindo (CD) system.7 Mean values with standard deviations (±SD) were computed and reported for all items. Mean age of the patients was 53.61 (±11.90) years. Mean body max index (BMI) was 24.22 (±2.51). Mean operative time was 85.2 (±13.1) minutes. Blood losses were minimal. No intraoperative complications are reported according to Satava classification. Four out of 18 patients (22.22%) experienced postoperative complications according to CD system. All patients had sexual intercourse for the first time postsurgery after a mean of 59.11 ± 2.08 days. Mean follow-up was 22.11 (±9.95). Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Distal corporoplasty was first described by Mulcahy. He reported a series of 14 patients with a follow-up of about 2 years with optimal functional outcomes. Moreover, distal corporoplasty resulted in shorter operative time, better function, less pain, and fewer recurrences than Gortex windsock repair.10 In our experience, distal corporoplasty is a simple and safe procedure in the treatment of distal cylinders extrusion when the prosthetic material is not exposed to the exterior.

    Little has been known about the contractile characteristics of diabetic stomach. We investigated spontaneous contractions and responses to acetylcholine in the gastric muscle in diabetic patients and non-diabetic control subjects according to the region of stomach. Gastric specimens were obtained from 26 diabetics and 55 controls who underwent gastrectomy at Samsung Medical Center between February 2008 and November 2011. Isometric force measurements were performed using circular muscle strips from the different regions of stomach under basal condition and in response to acetylcholine. Basal tone of control was higher in the proximal stomach than in the distal (0.63 g vs 0.46 g, p = 0.027). However, in diabetics, basal tone was not significantly different between the proximal and distal stomach (0.75 g vs 0.62 g, p = 0.32). The distal stomach of diabetics had higher basal tone and lower frequency than that of control (0.62 g vs 0.46 g, p = 0.049 and 4.0/min vs 4.9/min, p = 0.049, respectively). After exposure to acetylcholine, dose-dependent increases of basal tone, peak, and area under the curve (AUC) were noticed in both proximal and distal stomach of the two groups. In the proximal stomach, however, the dose-dependent increase of basal tone and AUC was less prominent in diabetics than in control. On the contrary to control, the proximal to distal tonic gradient was not observed in diabetic stomach. Diabetic stomach also had lower frequency of spontaneous contraction in the distal stomach and less acetylcholine-induced positive inotropic effect in the proximal stomach than control. © 2013 John Wiley & Sons Ltd.

    Hayabusa has successfully returned its reentry capsule in Australia on June 13th, 2010. As detailed previously [1], a series of processes have been held in the JAXA's Planetary Material Curation Facility to introduce the sample container of reentry capsule into the pure nitrogen filled clean chamber without influence by water or oxygen, retrieve fine particles found inside the container, characterize them with scanning electron microscope (SEM) with energy dispersive X-ray spectroscopy (EDX), classify them into mineral or rock types, and store them for future analysis. Some of those particles are delivered for initial analysis to catalogue them [2-10]. The facility is demanded to develop new methodologies or train techniques to pick up the recovered samples much finer than originally expected One of them is the electrostatic micro-probe for pickups, and .a trial started to slice the fine samples for detailed analysis of extra-fine structures. Electrostatic nano-probe to be used in SEM is also considered and developed.. To maximize the scientific outputs, the analyses must go on .based on more advanced methodology or sophisticated ideas. So far we have identified those samples as materials from S-class asteroid 25143 Itokawa due to their consistency with results by remote near-infrared and X-rsy spectroscopy: about 1500 ultra-fine particles (mostly smaller than 10 microns) caught by Teflon spatula scooping, and about 100 fine particles (mostly 20-200 microns) collected by compulsory fall onto silica glass plates. Future schedule for sample distribution must be planned. The initial analyses are still in progress, and we will distribute some more of particles recovered. Then some part of the particles will be distributed to NASA, based on the Memorandum of Understanding (MOU) between Japan and U.S.A. for the Hayabusa mission. Finally, in the near future an international Announcement of Opportunity (AO) for sample analyses will be open to any interested researchers In

    Total gastrectomy leads to decreased quality of life, which is characterized by different symptoms of the postgastrectomy syndrome. Aim of this study was to investigate the correlation of different alimentary symptoms and habits in correlation with the reconstruction type after total gastrectomy. Between 2005-2009 34 patients after total gastrectomy for gastric cancer were evaluated with questionnaires. Twenty two had a standard Roux-en-Y reconstruction, while 12 Longmire type jejunal interposition. Early dumping syndrome was investigated with the Sigstad score. Most of the investigated parameters were similar in Roux-en-Y and Jejunal Interposition patients. Early dumping syndrome however occurred significantly less frequantly after jejunal interposition. Preservation of the duodenal passage after total gastrectomy reduces the prevalence of early dumping.

    This is a report on various post-gastrectomy reconstructive procedures, proceeding from personal experience had with 14 patients undergoing gastrectomy for carcinoma of the stomach and five patients with operations of esophagus and stomach for various pathological conditions. An assessment is done of the reconstructive methods used on the ground of objective indicators. All patients are subjected to enteral alimentation through nutritive jejunostomy. In the pre- and postoperatived periods, the trophic state of patients is evaluated on basis of biochemical, anthropometric and immunologic study data. Postoperatively, in those with small-intestinal reservoir a lower degree negative symptomatology is established, along with life style improvement. Post-gastrectomy patients presenting I-II (UICC) stage of the oncological disease are indicated for small-intestinal reservoir formation. In the overall therapeutic approach to post-gastrectomy patients adequate clinical therapeutic feeding proves absolutely indispensable.

    Gastric glomus tumors (GGTs) are unusual benign, subepithelial, mesenchymal neoplasms of modified smooth muscle cells representing a neoplastic counterpart of glomus bodies. A 38-year-old woman was admitted to our clinic presenting morbid obesity. Routine preoperative evaluations, such as laboratory analysis, abdominal ultrasonography, and upper gastrointestinal endoscopy, were performed. She underwent a classical laparoscopic sleeve gastrectomy (LSG). The postoperative course was uneventful and she was discharged for outpatient control. Her histopathology report revealed a GGT 0.8 cm in diameter. No further treatment was done and she had lost 28 kg at the postoperative sixth month. Here, we present the case of GGT, which was diagnosed incidentally after LSG. PMID:27284541

    Sleeve gastrectomy (SG) is a commonly performed bariatric procedure. Weight regain following SG is a significant issue. Yet the defining, reporting and understanding of this phenomenon remains largely neglected. Systematic review was performed to locate articles reporting the definition, rate and/or cause of weight regain in patients at least 2 years post-SG. A range of definitions employed to describe weight regain were identified in the literature. Rates of regain ranged from 5.7 % at 2 years to 75.6 % at 6 years. Proposed causes of weight regain included initial sleeve size, sleeve dilation, increased ghrelin levels, inadequate follow-up support and maladaptive lifestyle behaviours. Bariatric literature would benefit from standardising definitions used to report weight regain and its rate in clinical series. Larger prospective studies are required to further understand mechanisms of weight regain following SG.

    Wernicke's encephalopathy (WE) is one of the potential complications of obesity surgery. It is an acute neuropsychiatric syndrome resulting from thiamine deficiency often associated with repeated vomiting. The classic triad is frequently reported in these patients (optic neuropathy, ataxia and confusion), associated with uncommon features. Cerebral impairment affects the dorsal medial nucleus of the thalamus and the periaqueductal grey area, appearing on MRI, as hyperintense signals on T2, Flair and Diffusion weighted imaging. Early diagnosis and parenteral thiamine are required to decrease morbidity and mortality. We report a case of WE and Korsakoff's syndrome in a young obese patient after subtotal gastrectomy, who still has substantial sequelae. The contribution of MRI with diffusion-weighted imaging is illustrated. The interest of nutritional supervision in the first weeks and preventive thiamine supplementation in case of repeated vomiting are of particular importance in these risky situations.

    2010-01-01

    Introduction: Laparoscopic sleeve gastrectomy has rapidly gained popularity in the field of bariatric surgery, mainly due to its low morbidity and mortality. Traditionally, 4 to 6 trocars are used. Single-access surgery has emerged as an attempt to decrease incisional morbidity and enhance cosmetic benefits. We present our initial 7 patients undergoing single-incision laparoscopic sleeve gastrectomy using a novel technique for liver retraction. Methods: Patients who underwent single-incision laparoscopic sleeve gastrectomy between March 2009 and May 2009 were analyzed. A 4-cm left paramedian incision was used. Laparoscopic sleeve gastrectomy was performed in a standard fashion using a 40 French bougie. Results: Seven patients underwent single-incision sleeve gastrectomy at the University of Illinois at Chicago. They were all female with a mean age of 34 years. Preoperative BMI was 49kg/m2 (range, 39 to 64). There were no intraoperative complications. Mean operative time was 103 minutes. Estimated blood loss was minimal. All 7 patients were discharged on postoperative day 2 and were doing well without any complications at 3.1±0.7 months after surgery. Conclusion: Single-incision laparoscopic sleeve gastrectomy is safe and feasible and can be performed without changing the existing principles of the procedure. Our technique for internal liver retraction provides adequate exposure and is reproducible. Development of improved standard instrumentation is required for this technique to become popular.

    INTRODUCTION Duodenal stump disruption remains one of the most dreadful postgastrectomy complications, posing an overwhelming therapeutic challenge. PRESENTATION OF CASE The present report describes the extremely rare occurrence of a delayed duodenal stump disruption following total gastrectomy with Roux-en-Y esophagojejunostomy for cancer, because of mechanical obstruction of the distal jejunum resulting in increased backpressure on afferent limp and duodenal stump. Surgical management included repair of distal jejunum obstruction, mobilization and re-stapling of the duodenum at the level of its intact second part and retrograde decompressing tube duodenostomy through the proximal jejunum. DISCUSSION Several strategies have been proposed for the successful management post-gastrectomy duodenal stump disruption however; its treatment planning is absolutely determined by the presence or not of generalized peritonitis and hemodynamic instability with hostile abdomen. In such scenario, urgent reoperation is mandatory and the damage control principle should govern the operative treatment. CONCLUSION Considering that scientific data about duodenal stump disruption have virtually disappeared from the current medical literature, this report by contradicting the anachronism of this complication aims to serve as a useful reminder for gastrointestinal surgeons to be familiar with the surgical techniques that provide the ability to properly manage this dreadful postoperative complication.

    2011-01-01

    Here we report the method of anastomosis based on double stapling technique (hereinafter, DST) using a trans-oral anvil delivery system (EEATM OrVilTM) for reconstructing the esophagus and lifted jejunum following laparoscopic total gastrectomy or proximal gastric resection. As a basic technique, laparoscopic total gastrectomy employed Roux-en-Y reconstruction, laparoscopic proximal gastrectomy employed double tract reconstruction, and end-to-side anastomosis was used for the cut-off stump of the esophagus and lifted jejunum. We used EEATM OrVilTM as a device that permitted mechanical purse-string suture similarly to conventional EEA, and endo-Surgitie. After the gastric lymph node dissection, the esophagus was cut off using an automated stapler. EEATM OrVilTM was orally and slowly inserted from the valve tip, and a small hole was created at the tip of the obliquely cut-off stump with scissors to let the valve tip pass through. Yarn was cut to disconnect the anvil from a tube and the anvil head was retained in the esophagus. The end-Surgitie was inserted at the right subcostal margin, and after the looped-shaped thread was wrapped around the esophageal stump opening, assisting Maryland forceps inserted at the left subcostal and left abdomen were used to grasp the left and right esophageal stump. The surgeon inserted anvil grasping forceps into the right abdomen, and after grasping the esophagus with the forceps, tightened the end Surgitie, thereby completing the purse-string suture on the esophageal stump. The main unit of the automated stapler was inserted from the cut-off stump of the lifted jejunum, and a trocar was made to pass through. To prevent dropout of the small intestines from the automated stapler, the automated stapler and the lifted jejunum were fastened with silk thread, the abdomen was again inflated, and the lifted jejunum was led into the abdominal cavity. When it was confirmed that the automated stapler and center rod were made completely linear

    Objectives To retrospectively evaluate the effectiveness of gastroesophageal stenting for post sleeve gastrectomy staple line leaks using removable self-expandable stents. Methods Between April 2012 and June 2015, 12 consecutive patients (6 males) with mean age of 34 years: (21-38 years) presented with staple line leak 1-8 weeks after the operation (mean 2.8 weeks). Patients underwent gastroesophageal stenting by interventional radiology. A total of 23 stents were deployed with mean length of 17.8 cm (7-24 cm) and mean diameter 25.6 mm (18-36 mm). Stent re-insertion was needed in 7 patients (9 procedure), while 6 patients required percutaneous collection drainage and 3 patients required endoscopic glue injection with clipping. Two stent removal procedures were carried out under endoscopic visualization after failed stent capture under fluoroscopy, while the remaining stents were successfully removed by interventional radiology. Results Stent placement was technically successful in all patients. Stent migration occurred in 6 patients (50%). There is a tendency for stent migration with shorter stent length (R= -0.557, p=0.008). The mean duration of stenting was 60.5 days (14-137 days). All patients underwent stent removal and resumed oral intake with no recurrence of leak at a mean follow up time of 190 days (14-410 days). Complications included gastrointestinal bleeding (n=1), proximal esophageal stricture (n=1) and stent occlusion (n=1). Conclusion Gastroesophageal stenting as a primary measure after diagnosis of early post sleeve gastrectomy leak appears to offer a safe and effective alternative option in obviating repeat surgical interventions. Minimally invasive interventions may still be required for the management of persistent leak. PMID:27874149

    Abstract Gastric cancer constitutes a major health problem. Robotic surgery has been progressively developed in this field. Although the feasibility of robotic procedures has been demonstrated, there are unresolved aspects being debated, including the reproducibility of intracorporeal in place of extracorporeal anastomosis. Difficulties of traditional laparoscopy have been described and there are well-known advantages of robotic systems, but few articles in literature describe a full robotic execution of the reconstructive phase while others do not give a thorough explanation how this phase was run. A new reconstructive approach, not yet described in literature, was recently adopted at our Center. Robotic total gastrectomy with D2 lymphadenectomy and a so-called “double-loop” reconstruction method with intracorporeal robot-sewn anastomosis (Parisi's technique) was performed in all reported cases. Preoperative, intraoperative, and postoperative data were collected and a technical note was documented. All tumors were located at the upper third of the stomach, and no conversions or intraoperative complications occurred. Histopathological analysis showed R0 resection obtained in all specimens. Hospital stay was regular in all patients and discharge was recommended starting from the 4th postoperative day. No major postoperative complications or reoperations occurred. Reconstruction of the digestive tract after total gastrectomy is one of the main areas of surgical research in the treatment of gastric cancer and in the field of minimally invasive surgery. The double-loop method is a valid simplification of the traditional technique of construction of the Roux-limb that could increase the feasibility and safety in performing a full hand-sewn intracorporeal reconstruction and it appears to fit the characteristics of the robotic system thus obtaining excellent postoperative clinical outcomes.

    The aim of the present study was to evaluate the safety of gastrectomy without nasogastric and nutritional intubations. Between January 2010 and August 2015, 74 patients with gastric cancer received total gastric resection and esophagogastric anastomosis without nasogastric and nutritional intubations at the First Department of Digestive Surgery of the XiJing Hospital of Digestive Diseases (Xi'an, China), of whom 42 were also received earlier oral feeding within 48 h. The data were retrospectively analyzed. An additional 301 cases who underwent traditional postoperative intubation were used for comparison. In patients without intubation compared with those managed traditionally with intubation, the mean operative time was decreased (190.97±38.18 vs. 216.12±59.52 min, respectively; P=0.026). In addition, the postoperative activity was resumed earlier (1.16±0.47 vs. 1.36±0.84 days, respectively; P=0.009), oral food intake was started earlier (4.28±1.79 vs. 5.71±2.66 days, respectively; P=0.009), the incidence of fever was lower (12.16 vs. 29.23%, respectively; P=0.003), and the incidence of total complications was not statistically significantly different between the two groups (9.41 vs. 6.31%, respectively; P=0.317). There were no significant differences regarding complications of the anastomotic port (1.37 vs. 1.69%, respectively; P=0.849). Compared with traditional postoperative management, earlier oral feeding did not increase the incidence of complications (7.21 vs. 4.76%, respectively; P=0.557). Our results suggest that total gastric resection without nasogastric and nutritional intubation is a safe and feasible option for patients undergoing total gastrectomy. PMID:28894580

    Background and Objectives: Treatment of gastroesophageal reflux disease (GERD) with hiatal hernia in obese patients has proven difficult, as studies demonstrate poor symptom control and high failure rates in this patient population. Recent data have shown that incorporating weight loss procedures into the treatment of reflux may improve overall outcomes. Methods: We retrospectively reviewed 28 obese and morbidly obese patients who presented from December 2007 through July 2013 with large or recurrent type 3 or 4 paraesophageal hernia. All of the patients underwent combined paraesophageal hernia repair and partial longitudinal gastrectomy. Charts were retrospectively reviewed, and the patients were contacted to determine symptomatic relief. Results: Mean preoperative body mass index was 38.1 ± 4.9 kg/m2. Anatomic failure of prior fundoplication occurred in 7 patients (25%). The remaining 21 had primary paraesophageal hernia, 3 of which were type 4. Postoperative complications included pulmonary embolism (n = 1), pulmonary decompensation (n = 2), and wound infection (n = 1). Mean hospital stay was 5 ± 3 days. Upper gastrointestinal esophagogram was performed in 21 patients with no immediate recurrence or staple line dehiscence. Mean excess weight loss was 44 ± 25%. All of the patients surveyed experienced near to total resolution of their preoperative symptoms within the first month. At 1 year, symptom scores decreased significantly. At 27 months, however, there was a mild increase in the scores. Return of severe symptoms occurred in 2 patients, both of whom underwent conversion to gastric bypass. Conclusions: Combined laparoscopic paraesophageal hernia repair with longitudinal partial gastrectomy offers a safe, feasible approach to the management of large or recurrent paraesophageal hernia in well-selected obese and morbidly obese patients. Short-term results were promising; however, intermediate results showed increasing rates of reflux symptoms that required

  13. Curation of Samples from Mars

    NASA Astrophysics Data System (ADS)

    Lindstrom, D.; Allen, C.

    One of the strong scientific reasons for returning samples from Mars is to search for evidence of current or past life in the samples. Because of the remote possibility that the samples may contain life forms that are hazardous to the terrestrial biosphere, the National Research Council has recommended that all samples returned from Mars be kept under strict biological containment until tests show that they can safely be released to other laboratories. It is possible that Mars samples may contain only scarce or subtle traces of life or prebiotic chemistry that could readily be overwhelmed by terrestrial contamination. Thus, the facilities used to contain, process, and analyze samples from Mars must have a combination of high-level biocontainment and organic / inorganic chemical cleanliness that is unprecedented. We have been conducting feasibility studies and developing designs for a facility that would be at least as capable as current maximum containment BSL-4 (BioSafety Level 4) laboratories, while simultaneously maintaining cleanliness levels exceeding those of the cleanest electronics manufacturing labs. Unique requirements for the processing of Mars samples have inspired a program to develop handling techniques that are much more precise and reliable than the approach (currently used for lunar samples) of employing gloved human hands in nitrogen-filled gloveboxes. Individual samples from Mars are expected to be much smaller than lunar samples, the total mass of samples returned by each mission being 0.5- 1 kg, compared with many tens of kg of lunar samples returned by each of the six Apollo missions. Smaller samp les require much more of the processing to be done under microscopic observation. In addition, the requirements for cleanliness and high-level containment would be difficult to satisfy while using traditional gloveboxes. JSC has constructed a laboratory to test concepts and technologies important to future sample curation. The Advanced Curation

    Abstract Inflammatory markers, including C-reactive protein (CRP) and white blood cell (WBC), are widely available in clinical practice. However, their predictive roles for infectious complications following laparoscopy-assisted gastrectomy (LAG) have not been investigated. Our aim was to investigate the diagnostic accuracy of CRP concentrations and WBC counts for early detection of infectious complications following LAG and to construct a nomogram for clinical decision-making. The clinical data of consecutive patients who underwent LAG with curative intent between December 2013 and March 2015 were prospectively collected. Postoperative complications were recorded according to the Clavien–Dindo classification. The diagnostic value of CRP concentrations and WBC counts was evaluated by area under the curve of receiver-operating characteristic curves. Optimal cutoff values were determined by Youden index. Univariate and multivariate logistic regression analyses were performed to identify risk factors for complications, after which a nomogram was constructed. Twenty-nine of 278 patients (10.4%) who successfully underwent LAG developed major complications (grade ≥III). CRP concentration on postoperative day 3 (POD 3) and WBC count on POD 7 had the highest diagnostic accuracy for major complications with an area under the curve value of 0.86 (95% confidence interval [CI], 0.79–0.92] and 0.68 (95% CI, 0.56–0.79) respectively. An optimal cutoff value of 172.0 mg/L was identified for CRP, yielding a sensitivity of 0.79 (95% CI, 0.60–0.92) and specificity 0.74 (95% CI, 0.68–0.80). Multivariate analysis identified POD3 CRP concentrations ≥172.0 mg/L, Eastern Cooperative Oncology Group Performance Status ≥1, presence of preoperative comorbidity, and operation time ≥240 min as risk factors for major complications after LAG. The optimal cut-off value of CRP on POD3 to predict complications following LAG was 172.0 mg/L and a CRP-based nomogram may

    Whether patients who have undergone gastrectomy are at a high risk of developing pyogenic liver abscess (PLA) remains debatable. From the inpatient claims records of Taiwan’s National Health Insurance Research Database, we identified 33 834 patients with a history of 2000–2010 and135 336 controls without a history of gastrectomy. The 2cohorts were matched by age, sex, and admission year and followed-up until the end of 2011 for estimating the risk of PLA. Overall, the incidence of PLA was 3.5-fold higher in the gastrectomy cohort than in the control cohort (21.6 vs 5.76 per 10 000 person-y). The adjusted hazard ratio (aHR) for the gastrectomy cohort obtained using the multivariate Cox proportional hazards regression model was 3.08 (95% confidence interval [CI] = 2.60–3.64). An elevated post gastrectomy PLA risk was observed in both men and women. Age-specific data revealed that the aHR for the gastrectomy cohort, compared with the control cohort, was the highest in patients younger than 50 years (aHR = 5.16, 95% CI = 2.96–9.01). An addition analysis showed that the gastrectomy cohort exhibited an elevated PLA risk regardless of whether the patients underwent total or partial gastrectomy. Patients with a history of gastrectomy exhibit a high risk of PLA. PMID:27671754

    Refinements in microsurgery have made distal finger replantation an established technique with high success rates and good functional and aesthetic outcomes. However, it still represents a technically demanding procedure due to the small vessel caliber and frequent lack of vessel length, requiring the use of interpositional venous grafts in some instances. We describe a new technique for anastomosis in fingertip replantation, whereby the need for venous grafts is eliminated. Applying the reverse distal transverse palmar arch technique, 11 cases of distal digital replantation were performed between January 2011 and July 2016. The described procedure was used for arterial anastomosis in 10 cases and arteriovenous shunting for venous drainage in 1 case. A retrospective case review was conducted. The technical description and clinical outcome evaluations are presented. Ten of the 11 replanted digits survived, corresponding to an overall success rate of 91%. One replant failed due to venous insufficiency. Blood transfusions were not required for any of the patients. Follow-up (range, 1.5-5 months) revealed near-normal range of motion and good aesthetic results. All of the replanted digits developed protective sensation. The average length of hospital admission was 5 days. All patients were satisfied with the results and were able to return to their previous work. The use of the reverse distal transverse palmar arch is a novel and reliable technique in distal digital replantation when an increase in vessel length is required, allowing for a tension-free arterial repair without the need for vein grafts.

    Vitamin B12 deficiency is more commonly found among patients who have undergone Roux-en-Y gastric bypass (RYGB) as compared to those with post-sleeve gastrectomies (SG). The major difference between SG and RYGB is that the latter greatly bypasses the stomach whereas the former simply reduces the gastric volume. The aim of this article was to study the stomach and the distal ileum histologically in a cadaver with SG to explain the higher rate of incidences of vitamin B12 deficiency seen in patients post-RYGB relative to patients post-SG. Since the stomach is the major variable in these two procedures, we hypothesize that it has the ability to regenerate and increase its surface area to compensate for the loss of its volume in SG patients. Tissue biopsies and hematoxylin and eosin stains were performed from various anatomical locations of the GI tract, specifically the gastric fundus, body, and antrum, and from the distal ileum of the small intestine of a cadaver with SG and another without SG (control). Compared with the control, the SG cadaver's gastric tissue biopsies were significant for chronic gastritis and hypertrophy of the muscularis externa layer. More importantly, parietal cell hyperplasia and deeper mucosal glands were also noted in the SG cadaver supporting the hypothesis. The compensatory role of an intact stomach, given its ability to regenerate parietal cells and increase its numbers in the gastric fundus and body, can be better appreciated in a gastric-sparing procedure such as SG versus RYGB in terms of limiting vitamin B12 deficiencies.

    The aim of this study was to compare surgical outcomes of patients with gastric cancer undergoing reduced port totally laparoscopic-assisted total gastrectomy (duet TLTG) with those of patients undergoing conventional laparoscopic-assisted total gastrectomy (LATG). Between January 2013 and 2015, 54 patients with gastric cancer underwent LATG at the Samsung Medical Center. Duet TLTG using 3 ports was performed in 30 patients, and conventional LATG using 5 ports was performed in 24 patients. Either extracorporeal or intracorporeal anastomosis was used for esophagojejunostomy. Surgical outcomes were compared between the operation methods. The operating time was similar for duet TLTG and conventional LATG [222 min (range, 163 to 287 min) vs. 233 min (range, 170 to 310 min), respectively; P=0.807]. Blood loss during surgery was also similar between duet TLTG and conventional LATG groups [100 mL (range, 50 to 400 mL) vs. 175 mL (range, 50 to 400 mL), respectively; P=0.249]. The median number of nodes dissected [duet TLTG vs. conventional LATG, 47 (20 to 67) vs. 41 (22 to 70), P=0.338] was not different between groups. Pain scores were 3.9, 3.3, and 2.9, and 3.9, 3.4, and 2.8, at postoperative days 1, 3, and 5, respectively, in the duet TLTG and the conventional LATG groups (P=0.857, 0.659, and 0.427, respectively). Overall complication rates in the duet TLTG and conventional LATG groups were not significantly different (36.7% vs. 16.7%, P=0.103). Duet TLTG is an acceptable procedure with quality of lymph node dissection, including the number of dissected lymph nodes and morbidity.

    Improved health care in Nicaragua is a major priority of the Sandinista revolution; it has been pursued by major reforms of the national health care system, something few developing countries have attempted. In addition to its internationally recognized advances in public health, considerable progress has been made in health care delivery by expanding curative medical services through training more personnel and building more facilities to fulfill a commitment to free universal health coverage. The very uneven quality of medical care is the leading problem facing curative medicine now. Underlying factors include the difficulty of adequately training the greatly increased number of new physicians. Misdiagnosis and mismanagement continue to be major problems. The curative medical system is not well coordinated with the preventive sector. Recent innovations include initiation of a "medicina integral" residency, similar to family practice. Despite its inadequacies and the handicaps of war and poverty, the Nicaraguan curative medical system has made important progress. PMID:2705603

    Solitary metastasis of a malignancy to the spleen is rare, particularly for gastric cancer. Only a few case reports have documented isolated splenic metastasis from early gastric cancer. We describe a case of splenic metastasis from early gastric cancer. A 60-year-old man underwent a distal gastrectomy for early gastric cancer. It infiltrated the submucosa with pathological nodal involvement (pT1bN2M0, stage IIB). One year after the gastrectomy, an abdominal computed tomography scan showed a low-density lesion, 17 mm in diameter, at the upper pole of the spleen. Positron emission tomography/computed tomography showed focal accumulation of fluorine-18 fluorodeoxyglucose in the spleen without extrasplenic tumor dissemination or metastasis. We diagnosed splenic metastasis of gastric cancer, and performed a splenectomy. Histological examination confirmed moderately differentiated tubular adenocarcinoma and poorly differentiated adenocarcinoma (solid type) that was consistent with the features of the primary gastric cancer. The splenic tumor was pathologically and immunohistochemically diagnosed as a metastasis from the gastric carcinoma. More than 18 months after the splenectomy, the patient has had no evidence of recurrent gastric cancer. When solitary metastasis to the spleen is suspected during the postoperative follow-up of a patient with gastric cancer, a splenectomy is a potentially effective treatment.

    Robotic gastrectomy has become increasingly popular in the treatment of gastric cancer, especially in Asian countries. The use of indocyanine green fluorescence has been reported in lymphatic mapping for gastric cancer in laparoscopic gastrectomy; however, there have been few reports regarding the use of indocyanine green in robotic gastrectomy. From January 2011 to March 2016, a total of 79 patients underwent robotic gastrectomy for gastric cancer. Among them, intraoperative subserosal injection (n = 9) or preoperative submucosal injection (n = 5) of indocyanine green with near-infrared imaging was performed in 14 patients, and the other 65 patients underwent robotic gastrectomy without the use of indocyanine green. There was no significant difference in the operative time, total number of retrieved lymph nodes, operative blood loss, and postoperative hospital stay between the patients who underwent robotic gastrectomy with or without indocyanine green fluorescence. For each lymph node station, there was significantly more number of retrieved lymph nodes in the indocyanine green group than in the no-indocyanine green group at the greater curvature side of the low body (#4d) to the infrapyloric region (#6) of the stomach. Five of the 14 patients who received an indocyanine green injection for lymphatic mapping had lymph node metastasis, and metastatic lymph nodes were located in the lymph node stations as detected by indocyanine green fluorescence during surgery. Indocyanine green fluorescence with near-infrared imaging is feasible and is a promising method of lymphatic mapping in robotic gastrectomy for gastric cancer. In future studies, larger patient numbers and long-term follow-up are required.

    The main complication observed after total gastrectomy is the oesophagojejunal anastomosic fistla. Its incidence varies between 7.4% and 11.5%. The mortality after anastomic leafage is high at around 20%, representing 30% and 54% of global mortality after total gastrectomy. This study aimed to evaluate mortality and morbidity after total gastrectomy and to determine their predictive factor this is retrospective study about 80 cases of total gastrectomy for gastric cancer, collected in the departmentof General Surgery of the University Hospital Habib Thameur Tunis during the period 1 January 1995 to 31 December 2010. Reconstruction of the alimentary tract was achieved by Roux-en-Y-jejunal-loop. Esophagojejunal anastomotic leeakage developed in 14 patients (17%). In 8 patients treatment of anastomotic leakage consisted of re-operation with surgical drainage and confection of jejunostomy. in one patient treatment required resutre of the anastomosis and drainage of an abscess. In one patient treatment required resuture of the anastomosis and drainage of an abscess. in 5 of the 14 patients with a proven leak of oesophagojejunal anastomosis, conservative treatment with parental alimentation, placement of an irrigation-aspiration system and systemic antibiotics was performed. This treatment was successful in all cases. The presence of anastomic fistula extends the median lenght of post operative stay in the hospital of 20 days compared for the payents withiut fistula.Global mortalilty was 8/80 (10%). After esophagojejunal anastomotic leakage, the mortality was 3/8 (21%). Leakage of the oesophago-intestinal anastomosis may occur after total gastrectomy for gastric cancer. it's serious complication contributes to mortality after total gastrectomy. Knowledge of the predective factors of esophagojejunal fistula after total gastrectomy in gastric cancer can decrease its incidence .

    The Internet is an important source of information for morbidly obese patients who are potential candidates for bariatric procedures. Over the past few years, there is growing demand for sleeve gastrectomy because of perceived technical ease balanced with excellent outcomes. The aim of this study was to assess the quality and content of available internet information pertaining to sleeve gastrectomy. Our hypothesis is that this information is inconsistent and inaccurate. A total of 50 websites were analyzed in September 2013. We used the search term "sleeve gastrectomy" to identify sites on the most common internet search engines: Google, Yahoo, Bing, and Ask. Based on popularity of use, 20 websites were obtained through the Google engine and 10 sites by each of the others. Websites were classified as academic, physician, health professional, commercial, social media, and unspecified. Quality of information was evaluated using the DISCERN score, the Journal of the American Medical Association (JAMA) benchmark criteria, and the Health on the Net code (HONcode) seal accreditation. The DISCERN score varies from 0-80 points and is based on 16 questions that evaluate publication quality and reliability. The JAMA benchmark criteria range from 0-4 points assessing website authorship, attribution, disclosure, and currency. HONcode certification was assessed as present or absent website accreditation. Duplicate and inaccessible websites were excluded from the analysis. We identified 43 websites from the United States, 6 from Mexico, and 1 from Australia. The average DISCERN and JAMA benchmark scores for all websites were 46.3±14.5 and 1.6±1.1, respectively, with a median DISCERN of 48.5 (range, 16-76) and JAMA score of 2.0 (range, 0-4). Website classification distribution was 21 physician, 11 academic, 7 commercial, 5 social media, 4 unspecified, and 2 health professional. The average DISCERN and JAMA benchmark scores were 55.4±13.4 and 2.4±1.0 in the academic group, 49

    This paper is about a posttraumatic distal ulnar artery thrombosis case that has occurred after a single blunt trauma. The ulnar artery thrombosis because of chronic trauma is a frequent condition (hypothenar hammer syndrome) but an ulnar artery thrombosis because of a single direct blunt trauma is rare. Our patient who has been affected by a single blunt trauma to his hand and developed ulnar artery thrombosis has been treated by resection of the thrombosed ulnar artery segment. This report shows that a single blunt trauma can cause distal ulnar artery thrombosis in the hand and it can be treated merely by thrombosed segment resection in suitable cases. PMID:25276455

    Proximal gastrectomy is not widely performed because the procedure is complicated, particularly under laparoscopy. We developed a simple laparoscopic technique of hand-sewn esophagogastrostomy with an anti-reflux mechanism. This study aimed to evaluate and compare the postoperative body weight loss (BWL) and quality of life (QOL) following laparoscopic proximal gastrectomy (LPG) and laparoscopic total gastrectomy (LTG) in patients with upper gastric cancer. We retrospectively analyzed patients with stage I upper gastric cancer undergoing LPG or LTG at Kyoto University Hospital between March 2006 and June 2014. The main outcome measures were the % BWL 1 year after gastrectomy, postoperative anastomotic stricture, and reflux esophagitis. Additionally, patient-reported outcomes were evaluated using the Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 in patients presenting at the outpatient clinic and exhibiting no recurrence. A total of 62 patients were included in this study (LTG, n = 42 vs. LPG, n = 20). The % BWL at 12 months in the LPG group was less than that in the LTG group (-16.3 vs. -10.7%). Multivariate analysis revealed that LPG was associated with less BWL (P = 0.003). Anastomotic stricture occurred more frequently in the LPG group than in the LTG group (0 vs. 25%). One patient in each group exhibited grade B severity of reflux esophagitis (based on the Los Angeles classification). In the questionnaire survey, LPG was better than LTG in terms of diarrhea and dissatisfaction with symptoms. In terms of reflux symptoms, patients in the LPG group experienced less acid and bile regurgitation symptoms compared with those in the LTG group. LPG with hand-sewn esophagogastrostomy results in less postoperative BWL and better QOL than LTG despite higher rates of anastomotic stricture.

    Cancer-related gastrectomy can cause post-gastrectomy syndrome, which includes weight loss, dumping syndrome, and reflux esophagitis and negatively affects the quality of life. Comprehensive and individualized patient management is required; however, there is a limit to Western medicine's ability to treat these symptoms. Kampo, a traditional Japanese medicine, adapts treatments to each individual's symptoms and constitution. We treated a 68-year-old male patient with post-gastrectomy syndrome using senpukukataishasekito, a Kampo medicine. He was diagnosed with Stage II-A gastric cancer at age 66 years and underwent a laparoscopic, pylorus-preserving gastrectomy followed by chemotherapy for 13 months. He visited our clinic for chemotherapy-related fatigue, postsurgical weight loss, and limb numbness. He was prescribed both hachimijiogan and hochuekkito. At the second visit, he complained of stomach discomfort, so we prescribed senpukukataishasekito. As his stomach function improved, his body weight increased and his fatigue decreased. We suggest that senpukukataishasekito may be an effective treatment for post-gastrectomy syndrome.

    The creation of Hunt-Lawrence jejunal pouches after total gastrectomy is associated with a better quality of life compared with the standard Roux-en-Y esophagojejunostomy. To the authors' knowledge, this is the first video to show the technical aspects of creating a jejunal pouch during a laparoscopic total gastrectomy. A 35-year-old woman was seen for surgical evaluation of a newly diagnosed CDH1 gene mutation. The authors recommended a laparoscopic total gastrectomy with Hunt-Lawrence pouch reconstruction. The jejunal pouch was created using an extracorporeal approach after removal of the stomach. A laparoscopic gel port was then placed over the extraction site to maintain pneumoperitoneum to facilitate a laparoscopic esophagojejunal pouch anastomosis using a circular stapler. The patient was discharged home on postoperative day 4. Her pathology showed no gastric cancer, and all 31 lymph nodes harvested were free of malignancy. At 1 year postoperatively, she had lost 25 lb from her presurgerical weight and was maintaining a healthy body mass index of 24 kg/m(2). Hunt-Lawerence jejunal pouches have been shown to improve quality of life compared with esophagojejunostomy without pouch formation after total gastrectomy. This video shows a novel technique for jejunal pouch creation during laparoscopic total gastrectomy using a laparoscopic gel port after gastric extraction to facilitate a laparoscopic esophagojejunal pouch anastomosis.

    To evaluate the glycemic changes after gastrectomy in non-morbidly obese patients with gastric cancer (GC) and type 2 diabetes mellitus (T2DM). Between December 2011 and June 2014, we included 46 patients with gastric cancer and T2DM of a body mass index (BMI) < 30 kg/m2, who underwent gastrectomy in our center. The comparisons of FPGs in specific periods were performed according to age, extent of gastrectomy, reconstruction type, preoperative triglyceride (TG) level and so on. The non-morbidly obese patients experienced an improvement of glycemic control. T2DM resolution happened 3 weeks after surgery. FPG decreased significantly after postoperative day 21 compared to preoperative FPG. 32 patients experienced DM improvement after postoperative day 21. The age and relatively lower preoperative TG patients, who underwent total gastrectomy (P<0.001) or duodenal bypass reconstruction (Billroth II, Roux-en-Y gastrojejunostomy, or Roux-en-Y esophagojejunostomy, P=0.009) appeared to have a better glycemic control. Our finding observed through this simulation model suggested that non-morbidly obese patients may also benefit from metabolic surgery for glycemic control, associated with age, extent of gastrectomy, reconstruction type, and preoperative triglyceride level.

    Introduction Laparoscopic sleeve gastrectomy is a widely utilized and effective surgical procedure for dramatic weight loss in obese patients. Leak at the sleeve staple line is the most serious complication of this procedure, occurring in 1–3% of cases. Techniques to minimize the risk of sleeve gastrectomy leaks have been published although no universally agreed upon set of techniques exists. This report describes a single-surgeon experience with an approach to sleeve leak prevention resulting in a progressive decrease in leak rate over 5 years. Methods 1070 consecutive sleeve gastrectomy cases between 2012 and 2016 were reviewed retrospectively. Patient characteristics, sleeve leaks, and percent body weight loss at 6 months were reported for each year. Conceptual and technical changes aimed towards leak reduction are presented. Results With the implementation of the described techniques of the sleeve gastrectomy, the rate of sleeve leaks fell from 4% in 2012 to 0% in 2015 and 2016 without a significant change in weight loss, as depicted by 6-month change in body weight and percent excess BMI lost. Conclusion In this single-surgeon experience, sleeve gastrectomy leak rate has fallen to 0% since the implementation of specific technical modifications in the procedure. PMID:28761766

    Breast cancer is the most common malignant neoplasm in the female population. However, stomach is a rare site for metastasis, and can show up many years after initial diagnosis and treatment of the primary tumor. Analyze a case series of this tumor and propose measures that can diagnose it with more precocity. Were analyzed 12 patients with secondary gastric tumors. Immunohistochemistry has demonstrated that primary tumor was breast cancer. We retrieved information of age, histological type, interval between diagnosis of the primary breast cancer and its metastases, immunohistochemistry results, treatment and survival. The mean age was 71.3 years (ranging 40-86). Ten cases had already been underwent mastectomy in the moment of the diagnosis of gastric metastasis. Two patients had diagnosis of both primary and secondary tumors concomitantly. At average, diagnosis of gastric metastasis was seven years after diagnosis of primary breast cancer (ranging 0-13). Besides, nine cases had also metastases in other organs, being bones the most affected ones. Immunohistochemistry of the metastases has shown positivity for CK7 antibody in 83.34%, estrogen receptor in 91.67%, progesterone receptor in 66.67% and AE1AE3 antibody in 75%, considering all 12 cases. Moreover, CK20 was absent significantly (66.67%). The positivity of BRST2 marker did not present statistical significance (41.67%). Eight cases were treated with chemotherapy associated or not with hormonal blockade. Surgical treatment of gastric metastasis was performed in four cases: three of them with total gastrectomy and one with distal gastrectomy. Follow-up has shown a mean survival of 14.58 months after diagnosis of metastasis, with only two patients still alive. Patients with a history of breast cancer presenting endoscopic diagnosis of gastric cancer it is necessary to consider the possibility of gastric metastasis of breast cancer. The confirmation is by immunohistochemistry and gastrectomy should be oriented in

    The most prevalent fractures managed by trauma surgeons are those involving the distal radius. The injury occurs in two peaks of prevalence: the first peak around the age of 10 years and the second peak around the age of 60 years. Distal radius fracture management requires sensitive diagnostics and classification. The objectives of treatment are the reconstruction of a pain-free unlimited durable functioning of the wrist and avoidance of typical fracture complications. Non-operative conservative management is generally employed for stable non-displaced fractures of the distal radius with the expectation of a good functional outcome. Unstable comminuted fractures with intra-articular and extra-articular fragment zones are initially set in a closed operation and finally by osteosynthesis. An armament of surgical implants is available for instable fractures requiring fixation. Palmar locked plate osteosynthesis has been established in recent years as the gold standard for operative management of distal radius fractures. Complex Working Group on Osteosynthesis (AO) classification type 3 fractures require extensive preoperative diagnostics to identify and treat typical associated injuries around the wrist.

    A 67-year-old male underwent endoscopic submucosal dissection (ESD) to treat early gastric cancer (EGC) in 2001. The lesion (50 mm × 25 mm diameter) was histologically diagnosed as poorly differentiated adenocarcinoma, with an ulcer finding. Although the tumor was confined to the mucosa with no evidence of lymphovascular involvement, the ESD was regarded as a non-curative resection due to the histological type, tumor size, and existence of an ulcer finding (as indicated by the 2010 Japanese gastric cancer treatment guidelines, ver. 3). Despite strong recommendation for subsequent gastrectomy, the patient refused surgery. An alternative follow-up routine was designed, which included five years of biannual clinical examinations to detect and measure serum tumor markers and perform visual assessment of recurrence by endoscopy and computed tomography scan after which the examinations were performed annually. The patient’s condition remained stable for eight years, until a complaint of back pain in 2010 prompted further clinical investigation. Bone scintigraphy indicated increased uptake. Histological examination of biopsy specimens taken from the lumbar spine revealed adenocarcinoma resembling the carcinoma cells from the EGC that had been treated previously by ESD, and which was consistent with immunohistochemical findings of gastrointestinal tract cancer. Thus, the diagnosis of bone metastasis from EGC was made. The reported rates of EGC recurrence in surgically resected cases range 1.4%-3.4%, but among these bone metastasis is very rare. To our knowledge, this is the first reported case of bone metastasis from EGC following a non-curative ESD and occurring after an eight-year disease-free interval. PMID:23946610

    Laparoscopic sleeve gastrectomy (LSG) is a recent addition to the bariatric surgery armamentarium. It has been demonstrated to be an efficacious stand-alone bariatric procedure in regard to weight loss. This study evaluates the progress of our initial experience with LSG. Retrospective review of prospective data from 2008 to 2010. Compared data between our first operative year of experience with LSG (2008) and our third year of experience (2010). Data compared for up to three years postoperatively. End points were percentage of excess body weight loss (%EWL) and percentage of excess body mass index loss (%EBL). Institutional improvement in %EWL and %EBL rates as our collective experience increased with LSG. Mean increase in %EWL of 14 per cent and mean increase of %EBL of 22 per cent. In our first year performing LSG the institutional weight loss was <50 per cent EWL, which is often cited as a benchmark level for "success" after bariatric surgery. By our third year of experience with LSG we achieved an institutional weight loss >50 per cent EWL. Institutional improvement in weight loss results with LSG as the collective experience increased. Several factors could have contributed to this observation to include a surgical mentorship program and the institution of formal nutritional education. This study demonstrates that institutional experience is a significant factor in weight loss results with LSG.

    The aim of this study is to observe the psychological changes at one year postop in a group of patients undergoing laparoscopic vertical sleeve gastrectomy (GVL) and multidisciplinary follow- up. A total of 46 patients with a BMI-35 or higher, who were selected for GVL, completed psychological testing. After GVL surgery, patients received psychological, nutritional, and medical attention during 12 months, and they retook the same tests. Psychological tests showed an improvement on almost all scales tested, except perfectionism. The most significant change was in the benchmark for Eating Disorders with an improvement of 89% for bulimia (P<.01), and 55% for body dissatisfaction (P<.01) and ineffectiveness (P<.01). In quality of life there was an improvement of 57% in the change in health status (P<.01). During our study, a protocol involving GVL and multidisciplinary follow-ups seems proved to be an effective intervention for improving bulimic symptoms and quality of living. The results of these psychological changes are similar to Roux-en-Y Gastric bypass but different to vertical banded gastroplasty or adjustable gastric band, according to previous studies. However, long-term studies are necessary to confirm this trend. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    Background. The aim of this study was to investigate patient outcomes and nutritional deficiencies following sleeve gastrectomy (SG) during a follow-up of two years. Methods. Over a period of 56 months, all consecutive patients who underwent SG were documented in this prospective, single-center, observational study. The study endpoints included operative time, complication rates, nutritional deficiencies and percentage of excess weight loss (%EWL). Results. From September 26, 2005 to May 28, 2009, 82 patients (female : male = 48 : 34) with a mean age of 43.3 years (range: 22-64) and a preoperative BMI of 52.5 kg/m² (range: 36.8-77.0) underwent SG. Major complications were observed in 9.8% of the patients, with 1 death. During follow up 51.2% of patients were supplemented with iron, 36.6% with zinc, 37.8% with calcium, 26.8% with vitamin D, 46.3% with vitamin B12 and 41.5% with folic acid. %EWL was 54.3, 65.3 and 62.6% after 6, 12 and 24 months. Conclusion. SG as a single step procedure is an effective bariatric intervention. Nutritional deficiencies after SG can be detected by routine nutritional screening. Our results show that Vitamin B12 supplementation should suggest routinely after SG.

    Gastric remnants are an inevitable consequence of partial gastrectomy following resection for gastric cancer. The presence of gastric stumps is itself a risk factor for redevelopment of gastric cancer. Helicobacter pylori (H. pylori) infection is also a well-known characteristic of gastric carcinogenesis. H. pylori colonization in the remnant stomach therefore draws special interest from clinicians in terms of stomach cancer development and pathogenesis; however, the H. pylori-infected gastric remnant is quite different from the intact organ in several aspects and researchers have expressed conflicting opinions with respect to its role in pathogenesis. For instance, H. pylori infection of the gastric stump produced controversial results in several recent studies. The prevalence of H. pylori infection in the gastric stump has varied among recent reports. Gastritis developing in the remnant stomach presents with a unique pattern of inflammation that is different from the pattern seen in ordinary gastritis of the intact organ. Bile refluxate also has a significant influence on the colonization of the stomach stump, with several studies reporting mixed results as well. In contrast, the elimination of H. pylori from the gastric stump has shown a dramatic impact on eradication rate. H. pylori elimination is recognized to be important for cancer prevention and considerable agreement of opinion is seen among researchers. To overcome the current discrepancies in the literature regarding the role of H. pylori in the gastric stump, further research is required. PMID:24659869

    Management of super-super obese patients poses a particular challenge for bariatric surgeons. Many staged algorithms exist for these patients. Essentially all of these involve a lower-risk procedure like sleeve gastrectomy first before a definitive second-stage procedure like gastric bypass or duodenal switch. This study compares our results with 19 mini (one anastomosis) gastric bypass and 56 sleeve gastrectomy in super-super obese patients. Sleeve gastrectomy patients were significantly older. There was no mortality or major complication in either group. There was no minor complication in mini (one anastomosis) gastric bypass group compared to two in the sleeve gastrectomy group. Mini (one anastomsosis) gastric bypass patients experienced significantly higher weight loss compared to sleeve gastrectomy patients at 6 months, 1 year, and 2 years after surgery.

    Recently a number of surgeons have recommended radical resection of gastrinomas in Zollinger-Ellison syndrome (ZES). We have developed a useful technique for preoperative localization of gastrinomas--the selective arterial secretin injection test (SASI)--and we recommend an intraoperative secretin test (IOS) for deciding the radicality of resection of gastrinomas. Here the results of SASI and IOS tests in 11 patients with ZES are examined and compared with the results of other techniques. The SASI test localized gastrinomas in all of the patients, while the sensitivity of ultrasonography, computed tomography, arteriography, or portal venous blood samplings was between 1/11 and 5/11. On the basis of the results of the SASI test, radical resection of gastrinoma was performed in four patients (three pancreatoduodenectomies and one extirpation). After pancreatoduodenectomy, immunohistologic study of the specimen revealed multiple microgastrinomas and lymph node metastases in two patients and the coexistence of a microgastrinoma and a gastinoma in one patient. The IOS test was useful in the estimation of the advisability of radicality, and in two patients total gastrectomy was not performed because of the results of the IOS test. These four patients are well and have returned to work, and their serum gastrin levels are below 35 pg/mL. Thus we believe SASI and IOS tests are helpful for planning curative resection of gastrinomas. Images Fig. 2. Fig. 3. Fig. 4. Fig. 7. PMID:2589884

    A sample of ambulant Japanese-American men (ages 45-69 years), was divided into those having a previous partial gastrectomy and a control non-gastrectomy population. Three-hundred-and-forty-seven men with a history of partial gastrectomy weighed less and had lower values for serum cholesterol, triglyceride, and blood pressure than did the control population of 7,598 men. The depressed lipid and blood pressure values could not be entirely explained by the reduced weight. Likewise, none of these differences appeared related to diet or living habits. Those operated on for gastric ulcer had, on the average, lower systolic pressures than duodenal ulcer patients and those with gastrojejunal anastamoses had lower cholesterol levels than patients with a gastroduodenostomy.

    The authors discuss experience in combined gastrectomy in 206 patients with gastric carcinoma. They encountered 72 various postoperative complications which were not fatal. Fourteen patients died, which made up a total postoperative mortality of 6.8%. The most frequent and threatening complication was incompetence of the esophago-intestinal++ anastomosis, which occurred in 17 cases (8.3%) and was the cause of death of 6 patients (42.9%). The incidence of purulent and pleuropulmonary complications was 19.9 and 3.4%, respectively. Extensive lymphadenectomy was performed in combined gastrectomy in 40 cases, which accounted for 42.6% of all combined interventions. The incidence of complication was lowest in this group of patients (15%), and there were only 2 fatal outcomes (5%). The authors believe that total gastrectomy with omentectomy, splenectomy, resection of the lower esophagus, and extensive lymphadenectomy is the method of choice in surgical treatment of gastric carcinoma.

    We aim to review the available literature on obese patients treated with robotic or laparoscopic sleeve gastrectomy, in order to compare the clinical outcomes and intraoperative parameters of the two methods. A systematic literature search was performed in PubMed, Cochrane Library and EBSCOhost databases, in accordance with the PRISMA guidelines. Sixteen studies met the inclusion criteria incorporating 29,787 patients. Robotic sleeve gastrectomy (RSG) technique showed significantly higher mean operative time and increased length of hospital stay. Post-operative incidence of leakage, wound infection and bleeding, along with weight reduction, were comparable. The majority of the studies assessing charges found increased cost in RSG population. Well-designed, randomized controlled studies, comparing RSG to laparoscopic sleeve gastrectomy (LSG), are necessary to assess further their clinical outcomes and cost-effectiveness.

    Single-site laparoscopy (SSL) has emerged as an alternative technique for sleeve gastrectomy. The author describes the preclinical technique of SSL sleeve gastrectomy through a novel multichannel port device in the porcine model. Anesthetized swine underwent 3-cm longitudinal supra-umbilical incision. A multichannel port device was inserted. A gastric sleeve was created by multiple applications of a 60-mm stapler. The access device's channel housing was removed and the sleeve specimen exteriorized. The mean operative time was 60+/-10 minutes, and the mean estimated blood loss was 30+/-5 cc. The multichannel port device allowed induction and maintenance of pneumoperitoneum throughout the procedure (range 12-15 mm Hg) with efficient rotation and substantial abdominal wall torque and minimal instrument clashing. SSL sleeve gastrectomy in the porcine model was facilitated by the use of a novel multichannel port device. Clinical studies are warranted.

    Gastric cancer in remnant stomach is a rare tumor but with poor prognosis. Compared with conventional open surgery, laparoscopic gastrectomy has potential benefits for these patients due to advantages resulting from its minimally invasive approach. Herein, we report on three patients with gastric cancer in remnant stomach who underwent laparoscopic total gastrectomy with intracorporeal esophagojejunostomy successfully. The operative time was 280, 250 and 225 minutes, the estimated blood loss was 100, 80 and 50 ml and the length of postoperative hospital stay was seven, eight and nine days respectively. Our experience has suggested that laparoscopic total gastrectomy with intracorporeal esophagojejunostomy can be a safe, feasible and promising option for patients with gastric cancer in remnant stomach.

    Intracorporeal esophagojejunostomy after laparoscopic total gastrectomy is technically difficult because this procedure should be performed in a narrow surgical field in the upper abdomen even when completely laparoscopic approaches are used. The placement of the anvil of a circular stapling device into the esophagus and connection the instrument to the anvil are extremely difficult steps in this surgery. Therefore, we developed a simple technique for intracorporeal esophagojejunostomy using hemi-double stapling technique; we named this technique the efficient purse-string stapling technique (EST). More recently, we have developed a modified EST (mEST) that utilizes a new stainless steel anvil rod instead of a plastic rod. Relative to the plastic rod, the steel rod is reusable and shorter; thus, it was easier to perform anvil placement into the esophagus with the steel rod. Anvil preparation for mEST: a stainless steel rod is attached to the shaft of the anvil, and the needle and thread are sutured to the tip of the rod. After complete insertion of the anvil into the esophageal cavity, the needle and thread are used to penetrate the anterior esophageal wall, and the esophagus is then clamped using a linear stapler just distal to the site penetrated by the thread. The linear stapler is fired, and anvil placement in the esophagus is simultaneously accomplished. After the rod is removed from the anvil, the instrument is intracorporeally connected to the anvil and then fired to complete the gastrojejunostomy. This technique is simple and facilitates intracorporeal reconstruction procedures in laparoscopic total gastrectomy.

    Abstract PD morbidity and readmission pose a substantial clinical and economic burden to the healthcare system. Comprehensive PD complications and readmission data are essential for developing initiatives to improve patient care. No previous studies have extensively investigated PD complications after gastric cancer surgery. We investigated the incidence, types, treatment, and risk factors of 30-day postdischarge (PD) complications after gastric cancer surgery. Between 2010 and 2013, data concerning complications and readmission within 30 days of hospital discharge were prospectively collected in 2107 patients undergoing gastric cancer surgery. In total, 1642 patients (77.9%) underwent distal gastrectomy, 418 (19.8%) total gastrectomy, and 47 (2.3%) other procedures. Postoperative morbidity and mortality were 17.4% and 0.6%, respectively, with a mean 8.8-day hospital stay. Sixty-one patients (2.9%) developed 30-day PD morbidity (58 local and 3 systemic complications), accounting for 16.6% of overall morbidity; 47 (2.2%) were readmitted; and 7 (0.3%) underwent a reoperation. The mean time to PD complications was 9.5 days after index hospital discharge. The most common complication was intra-abdominal abscess (n = 14), followed by wound, ascites, and anastomosis leakage. No mortality occurred resulting from PD complications. In the univariate and multivariate analyses, underlying comorbidity (hypertension and liver cirrhosis) and obesity were independent risk factors for developing PD complications. The early PD period is a vulnerable time for surgical patients with substantial risk of complication and readmission. Tailored discharge plans along with appropriate PD patient support are essential for improving the quality of patient care. PMID:25789945

    2014-01-01

    Background This study aimed to determine early postoperative changes of plasma polyunsaturated fatty acids (PUFAs) following laparoscopic sleeve gastrectomy (LSG). Methods Ten obese patients (mean BMI: 51.10 ± 11.59 kg/m2) underwent LSG and eleven normal weight control patients (mean BMI: 24.37 ± 2.33 kg/m2) underwent laparoscopic abdominal surgery. Fasting blood samples were collected prior to surgery, at day 1 after surgery and after postoperation oral feeding. Plasma levels of arachidonic acid (AA, C20:4n6), dihomo-gamma-linolenic acid (DGLA, C20:3n6), eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6n3) were determined by an optimized multiple reaction monitoring (MRM) method using ultra fast-liquid chromatography (UFLC) coupled with tandem mass spectrometry (MS/MS). Prostaglandin E2 (PGE2) was measured in serum samples by enzyme immunoassay. Results A significant decrease was observed in insulin and HOMA IR levels in sleeve gastrectomy patients after postoperation oral feeding compared to preoperation. Plasma AA levels and AA/EPA ratio were significantly increased in sleeve gastrectomy patients after postoperation oral feeding compared to postoperation day 1. Serum PGE2 levels and AA/DHA ratio was significantly higher in sleeve gastrectomy patients at preoperation, postoperation day 1 and after postoperation oral feeding when compared to control group patients. Conclusion Increased peripheral insulin sensitivity associated with LSG may play a role in the significant increase of plasma AA levels in sleeve gastrectomy patients following postoperation oral feeding. The significant increase in PGE2 levels and AA/DHA ratio in sleeve gastrectomy group patients also confirms the presence of a proinflammatory state in obesity. PMID:24694037

    Analysis of a recent single state bariatric surgery registry revealed that laparoscopic sleeve gastrectomy was the most common bariatric procedure starting in 2012. The objective of this study was to examine the trend in utilization of laparoscopic sleeve gastrectomy performed at academic medical centers in the United States. Using ICD-9 diagnosis and procedure codes, clinical data obtained from the University HealthSystem Consortium database for all bariatric procedures performed for the treatment of severe obesity between October 1, 2011, and June 30, 2014. Quarterly trends in utilization for the 4 most commonly performed bariatric operations were examined, and comparisons between procedures were performed. A total of 54,953 bariatric procedures were performed. Utilization of laparoscopic sleeve gastrectomy increased from 23.7% of all bariatric procedures during the fourth quarter of 2011 to 60.7% during the second quarter of 2014 while laparoscopic gastric bypass decreased from 62.2% to 37.0%, respectively. Utilization of laparoscopic sleeve gastrectomy surpassed that of laparoscopic gastric bypass in the second quarter of 2013 (50.6% versus 45.8%). During the same time period, utilization of open gastric bypass fell from 6.6% to 1.5%, and the use of laparoscopic adjustable gastric banding decreased from 7.5% to .8%. Within the context of U.S. academic medical centers, there has been a significant increase in the utilization of laparoscopic sleeve gastrectomy, which has surpassed laparoscopic gastric bypass utilization since 2013. Laparoscopic sleeve gastrectomy is now the most commonly performed bariatric procedure at the national level within academic centers. Copyright © 2015 American Society for Bariatric Surgery.

    The Astromaterials Acquisition and Curation Office has the unique responsibility to curate NASA's extraterrestrial samples - from past and forthcoming missions - into the indefinite future. Currently, curation includes documentation, preservation, physical security, preparation, and distribution of samples from the Moon, asteroids, comets, the solar wind, and the planet Mars. Each of these sample sets has a unique history and comes from a unique environment. The curation laboratories and procedures developed over 40 years have proven both necessary and sufficient to serve the evolving needs of a worldwide research community. A new generation of sample return missions to destinations across the solar system is being planned and proposed. The curators are developing the tools and techniques to meet the challenges of these new samples. Extraterrestrial samples pose unique curation requirements. These samples were formed and exist under conditions strikingly different from those on the Earth's surface. Terrestrial contamination would destroy much of the scientific significance of extraterrestrial materials. To preserve the research value of these precious samples, contamination must be minimized, understood, and documented. In addition, the samples must be preserved - as far as possible - from physical and chemical alteration. The elaborate curation facilities at JSC were designed and constructed, and have been operated for many years, to keep sample contamination and alteration to a minimum. Currently, JSC curates seven collections of extraterrestrial samples: (a)) Lunar rocks and soils collected by the Apollo astronauts, (b) Meteorites collected on dedicated expeditions to Antarctica, (c) Cosmic dust collected by high-altitude NASA aircraft,t (d) Solar wind atoms collected by the Genesis spacecraft, (e) Comet particles collected by the Stardust spacecraft, (f) Interstellar dust particles collected by the Stardust spacecraft, and (g) Asteroid soil particles collected

    Phenex (http://phenex.phenoscape.org/) is a desktop application for semantically annotating the phenotypic character matrix datasets common in evolutionary biology. Since its initial publication, we have added new features that address several major bottlenecks in the efficiency of the phenotype curation process: allowing curators during the data curation phase to provisionally request terms that are not yet available from a relevant ontology; supporting quality control against annotation guidelines to reduce later manual review and revision; and enabling the sharing of files for collaboration among curators. We decoupled data annotation from ontology development by creating an Ontology Request Broker (ORB) within Phenex. Curators can use the ORB to request a provisional term for use in data annotation; the provisional term can be automatically replaced with a permanent identifier once the term is added to an ontology. We added a set of annotation consistency checks to prevent common curation errors, reducing the need for later correction. We facilitated collaborative editing by improving the reliability of Phenex when used with online folder sharing services, via file change monitoring and continual autosave. With the addition of these new features, and in particular the Ontology Request Broker, Phenex users have been able to focus more effectively on data annotation. Phenoscape curators using Phenex have reported a smoother annotation workflow, with much reduced interruptions from ontology maintenance and file management issues.

    There are many unsolved questions about safety of bariatric surgery in the context of severely obese patients living with human immunodeficiency virus (HIV) and notably on antiretroviral therapy (ART) absorption. Here, we provide the first case series of tenofovir disoproxil fumarate (TDF) pharmacokinetic in four HIV-infected patients before and after sleeve-gastrectomy. Our case-series showed a transient and reversible decrease of TDF bioavailability one month after sleeve-gastrectomy without any consequences on CD4 cells and HIV viral load. More studies are needed since the impact of bariatric surgery on drug absorptions in the field of infectious diseases remains poorly investigated.

    Background Recently, the right gastroepiploic artery (RGEA) has been used in coronary artery bypass grafting (CABG) as an alternative arterial graft. Unfortunately, an increased incidence of gastric cancers has been reported after CABG using the RGEA. Handling of the RGEA during gastrectomy in these patients may cause lethal complications, which sometimes reduces the feasibility of curative dissection of lymph nodes at the base of the graft. Case presentations We describe two cases of gastric cancer undergoing gastrectomy after CABG with the use of RGEA. To avoid the potentially fatal coronary event during gastrectomy, safe handling of the conduit including preparations for injuries and prevention of vessel spasm was performed in both cases, accompanied by an adequate monitoring of the systemic circulation. Intraoperative frozen section examination showed no lymph node metastasis around the graft in any of the cases; therefore, complete lymph node dissection at the base of the graft was not undertaken. No complications occurred during the operation. In addition to these two cases, twenty-four cases reported in the literatures were reviewed (a total of 26 cases). Ten early and 16 advanced gastric cancers were included. Among the 16 advanced gastric cancer cases, an alternative graft was employed in 8 due to the resection of an original graft to complete lymph node dissection. Mere handling of a graft often caused lethal complications suggesting that the operation should be completed by isolation of the graft. A pedicled graft harvesting via the ante-gastric route was popular. However, a skeletonized harvesting with resection of the pyloric branches of the RGEA would be better because this would interrupt the original lymph flow, which could eliminate the need for lymph node dissection and graft isolation. Among the 10 cases having early gastric cancers, 6 were found within 1.5 years after CABG. Early detection in these 6 cases was possible due to the use of gastric

    Objective To analyze fractures of the distal clavicle region in pediatric patients. Methods Ten patients between the ages of five to eleven years (mean of 7.3 years) were observed. Nine patients were treated conservatively and one surgically. All the fractures were classified using the Nenopoulos classification system. Results All the fractures consolidated without complications. Conservative treatment was used for nine patients, of whom three were in group IIIB, three IIb, two IIa and one IV. The only patient who was treated surgically was a female patient of eleven years of age with a group IV fracture. Conclusion The treatment indication for distal fractures of the clavicle in children should be based on the patient's age and the displacement of the fragments. PMID:26962489

    Metaphyseal and physeal fractures of the distal radius are common in children. Most cases are best treated with closed reduction and cast immobilization. Long-term outcomes of these injuries are excellent when specific treatment principles of reduction and casting are followed. Surgical indications are limited and include open fractures, intra-articular fractures, non-reducible fractures, unstable fractures, and the presence of associated nerve injury. Closed reduction and percutaneous pin fixation is the most commonly used surgical option. The clinician should be aware of delayed complications such as growth disturbance of the distal radius, and understand how to manage these problems to ensure successful long-term outcomes. Epiphysiodesis is uncommon but growth plate injuries need to be followed for one year.

  20. Distal esophageal spasm: an update.

    PubMed

    Achem, Sami R; Gerson, Lauren B

    2013-09-01

    Distal esophageal spasm (DES) is an esophageal motility disorder that presents clinically with chest pain and/or dysphagia and is defined manometrically as simultaneous contractions in the distal (smooth muscle) esophagus in ≥20% of wet swallows (and amplitude contraction of ≥30 mmHg) alternating with normal peristalsis. With the introduction of high resolution esophageal pressure topography (EPT) in 2000, the definition of DES was modified. The Chicago classification proposed that the defining criteria for DES using EPT should be the presence of at least two premature contractions (distal latency<4.5 s) in a context of normal EGJ relaxation. The etiology of DES remains insufficiently understood, but evidence links nitric oxide (NO) deficiency as a culprit resulting in a disordered neural inhibition. GERD frequently coexists in DES, and its role in the pathogenesis of symptoms needs further evaluation. There is some evidence from small series that DES can progress to achalasia. Treatment remains challenging due in part to lack of randomized placebo-controlled trials. Current treatment agents include nitrates (both short and long acting), calcium-channel blockers, anticholinergic agents, 5-phosphodiesterase inhibitors, visceral analgesics (tricyclic agents or SSRI), and esophageal dilation. Acid suppression therapy is frequently used, but clinical outcome trials to support this approach are not available. Injection of botulinum toxin in the distal esophagus may be effective, but further data regarding the development of post-injection gastroesophageal reflux need to be assessed. Heller myotomy combined with fundoplication remains an alternative for the rare refractory patient. Preliminary studies suggest that the newly developed endoscopic technique of per oral endoscopic myotomy (POEM) may also be an alternative treatment modality.

    Chronic distal tibiofibular syndesmosis disruption can be managed by endoscopic arthrodesis of the syndesmosis. This is performed through the proximal anterolateral and posterolateral portals. The scar tissue and bone block are resected to facilitate the subsequent reduction of the syndesmosis. The reduction of the syndesmosis can be guided either arthroscopically or endoscopically. The tibial and fibular surfaces of the tibiofibular overlap can be microfractured to facilitate subsequent fusion.

    Distal anterior cerebral artery (DACA) aneurysms, also known as pericallosal artery aneurysms, represent about 6% of all intracranial aneurysms. They are located on the A2-A5 segments of the anterior cerebral artery and on its distal branches. This paper summarizes present knowledge on radiological features, treatment options, treatment results, and long-term follow-up of DACA aneurysms. Typical features of DACA aneurysms are small size, broad base, and branches originating from the base. When ruptured, they cause intracerebral hematoma in nearly half of the cases. DACA aneurysms are nowadays more often treated with microsurgical clipping than endovascular coiling due to their distal location and morphologic features. With clipping the results are same or slightly better than for aneurysms at other locations, coiling is often associated with more complications than in other aneurysms. Clipping is a long-lasting treatment with very small recurrence rate, there is no long-term data available on efficacy of coiling yet. For ruptured DACA aneurysms the most important factors affecting outcome is the severity of initial bleeding and patient's age.

    During laparoscopic sleeve gastrectomy (LSG), adhesions between the stomach and the pancreas are sometimes found, forming a "gastropancreatic ligament" (GPL). However, the GPL has only been described once in the literature, in 1985. The objective of this study was to determine the incidence of the GPL during LSG, describe this structure and assess its effect on the surgical technique. All patients undergoing primary LSG in our institution (n = 240) and patients referred for gastric fistula (GF) after primary LSG (n = 18) between January 2015 and December 2015 were included. The primary endpoint was the incidence of a GPL during primary LSG. The secondary endpoints were the postoperative complication rate, the postoperative GF rate, and the presence of this ligament during reoperation for GF. Among the 240 patients, a GPL was visible in 49 cases (20.4%) and was described as thin in 34 of these (69.4%). Twelve postoperative complications (5%) were observed, including seven major (2.9%). The GF rate was 2% (n = 5), not requiring reoperation. The gastric stenosis rate was 0.4% (n = 1). The GPL had been previously sectioned in one of the five patients (20%) with postoperative GF. During the study period, 18 patients were referred for GF and 14 were reoperated. A non-sectioned GPL, not described in the operating report, was observed in four patients (28.5%). A GPL was identified in 20.4% of cases. Identification of a GPL could be important in the context of LSG, as section of the ligament allows tension-free stapling to be performed and can therefore possibly reduce the risk of postoperative complications, particularly GF.

    Laparoscopic sleeve gastrectomy (LSG) has gained popularity as the leading bariatric procedure for the treatment of morbid obesity. Due to the rising numbers of bariatric surgeries, neurologic complications have become increasingly recognized. Our aim was to examine biochemical and hormonal factors that are associated with neuropathy post-LSG. Thirty-two patients were included: 16 patients with neuropathy in the neuropathic group (NG) and 16 patients without neuropathy in the control group (CG). Diagnosis was made by a consultant neurologist, and blood samples were taken to examine vitamin deficiencies and hormones involved in neuropathy. There was no significant difference between the BMI (p = 0.1) in both groups as well as excess weight loss percentages post-LSG at 12 months (p = 0.6). B12 levels were within normal range, but higher in NG (p = 0.005). Vitamin B1 and B2 levels were significantly lower in NG; p values are 0.000 and 0.031, respectively. Vitamin B6 levels were significantly higher in NG (p = 0.02) and copper levels were lower in NG (p = 0.009). There was no significant difference in GLP-1 response in both groups. Our data showed post-LSG neuropathy is associated with lower levels of vitamin B1, B2, and copper, plus patients who are older in age. Vitamin B6 was significantly higher in the NG, which is, at toxic levels, associated with neuropathy. No difference in preoperative BMI, excess weight loss percent at 1 year, and GLP-1 levels was found. Larger data is required to validate our results.

    Although the frequency of laparoscopic total gastrectomy (LTG) has been increasing, the procedure requires considerable experience because of its technical difficulty and the concern for oncological safety. This study intended to define the learning curve associated with the procedure. All 256 cases of LTG performed from June 2003 to December 2012 were enrolled. The cases were divided into ten groups of 25 cases based on when they occurred. The learning curve was defined using the moving average method. LTG, performed in the absence of other procedures (pure-LTG, 132 cases), was extracted from the ten groups, and the mean operative time and estimated blood loss (EBL) were compared to define the learning curve. Retrieved lymph nodes, hospital stay, and complications were compared across the phases of the learning curve. LTG with spleen resection, performed in the absence of other procedures (pure-srLTG, 53 cases), was also analyzed by the same method. A three-phase learning curve of LTG was defined: the first two groups, the following two groups, and the final six groups (mean operative time: 223.0, 244.8, and 207.8 min, respectively, p = 0.003; mean EBL: 94.6, 237.0, and 116.5 ml, respectively, p < 0.001). The rates of complications and open conversions were similar across the three phases. There were no significant differences in mean operative time, EBL, retrieved LNs, hospital stay, or complication rates between pure-LTG and pure-srLTG, after completing the respective learning curves. Experience with approximately 100 LTG cases was required to complete learning of the procedure.

    Bariatric surgery is recognized as the most effective method for achieving relevant weight loss in subjects with severe obesity. However, there is insufficient knowledge about weight self-regulation and quality of motivation in these patients. The main goal of this study was to characterize the association between the percentage of excess weight loss (%EWL) and the motivation to manage weight, at least 1 year after sleeve gastrectomy (SG). This is an observational longitudinal retrospective study. All patients corresponding to predefined inclusion criteria who underwent SG from January 2008 to July 2010 at a main general hospital were invited. A version of the Treatment Self-Regulation Questionnaire (TSRQ) was used to assess patients' quality of motivation: TSRQ concerning continuing the weight self-management program. Clinical data were collected from patients' records. Overall, 81 patients participated (16 men and 65 women, 25-64 years old). The average body mass index was significantly reduced from 45.3 ± 7.0 kg/m(2) preoperatively to 32.7 ± 6.9 kg/m(2) postoperatively. Autonomous self-regulation was higher than externally controlled self-regulation, regarding motives to keep managing weight after SG. Postoperatively, %EWL correlated negatively with external self-regulation. SG was found to be associated with the quality of motivation for losing weight. External motivations were associated with worse results. These findings support the importance of multiprofessional teams in the assessment and treatment of patients, aiming for the promotion of weight self-regulation after bariatric surgery.

    The use of laparoscopic sleeve gastrectomy (LSG) is increasing worldwide. Although post-LSG gastric stenosis (GS) is less frequent, it has not been well defined and lacks standardized management procedures. The objective of the present study was to describe a series of patients with GS symptoms after LSG and to develop a standardized management procedure for this complication. We performed a retrospective analysis of a prospective database of patients presenting with GS after LSG procedures performed between January 2008 and March 2014. The primary efficacy criterion was the frequency of post-LSG GS. GS was classified as functional (i.e. a gastric twist) or organic. The secondary efficacy criteria included the time interval between LSG and diagnosis of GS, the type of stenosis, the type of management, and the follow-up data. During the study period, 1210 patients underwent primary or secondary LSG. Seventeen patients had post-operative symptoms of GS (1.4%); one patient had achalasia that had not been diagnosed preoperatively and thus was excluded from our analysis. The median time interval between LSG and diagnosis of GS was 47.2 days (1-114). Eleven patients had organic GS and six had functional GS. Seven patients required nutritional support. Endoscopic treatment was successful in 15 patients (88.2%) after balloon dilatation (n = 13) or insertion of a covered stent (n = 2). Two of the 15 patients required conversion to Roux-en-Y gastric bypass (11.8%). GS after LSG is a rare complication but requires standardized management. Most cases can be treated successfully with endoscopic balloon dilatation.

    The aim of the present study was to investigate the age-specific prognostic factors in patients who underwent gastrectomy for gastric cancer. The medical records of 366 patients with gastric cancer who underwent surgical resection at our hospital between January 2007 and December 2014 were retrospectively reviewed. Of the 366 patients, 117 were aged 75 years or older and 249 were aged 74 years or younger. All factors that were identified as significant using univariate analysis were included in the multivariate analysis. The median follow-up duration was 52.9 months (range, 1.0-117.5 months). We found that in patients aged 75 years or older, postoperative complications and the extent of cancer were independent prognostic factors of overall survival and disease-free survival. In contrast, in patients aged 74 years or younger, only the lymph node status and postoperative chemotherapy were independent prognostic factors for overall survival and disease-free survival, respectively. Pathological outcomes and postoperative complications are important prognostic factors for survival in patients aged 75 years or older with gastric cancer, whereas pathological outcomes and postoperative chemotherapy are important prognostic factors for survival in patients aged 74 years or younger. Because the prevention of postoperative complications may contribute to improvements in the prognosis of elderly patients with gastric cancer, we suggest that it is necessary to consider limited surgery instead of radical surgery, depending on the patient's general condition and co-morbidities.

    Background. Weight loss and reduction in comorbidities can be achieved by longitudinal sleeve gastrectomy (LSG). Existing evidence suggests that LSG resolves or improves hyperlipidemia in morbidly obese patients. The aim of this study was to systematically review the effect of LSG on hyperlipidemia. Methods. A systematic literature search was conducted from English-language studies published from 2000 to 2012 for the following databases: MEDLINE, EMBASE, CINAHL, PubMed, Clinical evidence, Scopus, Dara, Web of Sciences, TRIP, Health Technology Database, Cochrane library, and PsycINFO. Results. A total of 4,211 articles were identified in the initial search, and 4,185 articles were excluded based on the exclusion criteria. Twenty-six studies met the inclusion criteria for this systematic review, involving 3,591 patients. The mean preoperative body mass index (BMI) was 48 ± 7.0 kg/m2 (range 37.2–65.3). The mean postoperative BMI was 35 ± 5.9 kg/m2 (range 26.3–49). The mean percentage of excess weight loss (EWL) was 63.1% (range 37.7–84.5), with a mean followup of 19.1 months (range 6–60). The mean levels of pre and post operative cholesterol were 194.4 ± 12.3 mg/dL (range 178–213) and 181 ± 16.3 mg/dL (range 158–200), respectively. Conclusion. Most patients with hyperlipidemia showed improvement or resolution of lipid profiles after LSG. Based on this systematic review, LSG has a significant effect on hyperlipidemia in the form of resolution or improvement in the majority of patients. PMID:24286009

    Background: The rising prevalence of obesity in today populations has led obese individuals to seek medical interventions. Aside from special diets, routine exercise and in some cases, medical treatment, most of the obese patients, favoring those with morbid or super obesity can benefit from bariatric surgery to lose weight. Laparoscopic sleeve gastrectomy (LSG) is relatively new method to limit the compliance of stomach. The consequent quick satiety during each meal results in gradual weight loss in patients. We investigated the efficacy and safety of this method among a group of our patients. Materials and Methods: This cross-sectional study was conducted in Isfahan, Iran, from January 2012 to January 2013. Thirty-five cases of obesity that had undergone LSG were enrolled and their baseline data of weight, body mass index (BMI), blood sugar, lipid profile, liver function indexes and blood pressure were collected. The patients were followed up for 6 months. The 6-month results were analyzed. Results: There was significant reduction in BMI, weight, blood sugar, blood pressure, liver enzymes and lipid profile components (P < 0.05), except for alkaline phosphatase (ALP) (P = 0.3). The average of excess weight loss percentage after 6 months was 69.2 ± 20.9%. No mortality occurred. Two of the patients had micro anastomotic leaks that were treated with nonoperative management. A case of gross leakage was treated with tube jejunostomy. Conclusion: Our study confirmed the efficacy and safety of LSG as a single surgical intervention for body weight reduction in morbidly and super obese patients. PMID:27110546

    Although laparoscopic sleeve gastrectomy (LSG) has been shown to have a long-term antidiabetic effect, little is known regarding the immediate response to surgery. This study's objective was to evaluate the glycemic and lipid metabolic response in the first postoperative week. The study included 21 obese diabetic participants. Glycemic markers, lipids, and hepatic function tests were measured just prior to surgery and at 1 week and 3 months postoperatively. Two participants were dropped prior to all measurements due to technical reasons, and two more were lost to follow-up. At 1 week after surgery, compared to preoperative baseline, we found reduced hemoglobin A1c (7.63 to 7.31, P < 0.001), insulin (24.96 to 10.92, P < 0.05), and borderline significant homeostatic model assessment insulin resistance (HOMA-IR, 9.48 to 3.91, P > 0.05). Low-density lipoprotein (LDL) cholesterol increased and high-density lipoprotein (HDL) cholesterol decreased. Three months after surgery, hemoglobin A1c, insulin, and HOMA-IR continued to decrease (6.05, 7.11, and 1.92, respectively, P < 0.05), with hemoglobin A1c correlated to weight loss (P < 0.05). Triglycerides, triglyceride to HDL ratio, and total cholesterol to HDL ratio also decreased, but there was no significant change in LDL cholesterol or HDL versus presurgery levels. Reduced triglyceride levels were correlated with reduced alanine transaminase (ALT) and gamma-glutamyl transpeptidase (GGT) (P < 0.05). LSG is associated with marked antidiabetic effects as early as 1 week after surgery, unrelated to weight loss. The antidiabetic effect improves at 3 months. Triglyceride reduction was associated with improved hepatic functions, but cholesterol did not show a meaningful reduction.

    Identifying eating and lifestyle behaviors prior to bariatric surgery may assist in better selecting and preparing patients and might lead to improved success rate. The current study aimed to assess eating behaviors and lifestyle trends among laparoscopic sleeve gastrectomy (LSG) candidates and to compare those trends between genders. This descriptive study was conducted in the bariatric clinic at the Haifa Assuta Medical Center. Data was gathered from medical records of LSG candidates that were evaluated before surgery in our institution between 2008 and 2011. The data included demographics, comorbidities, anthropometrics, weight management history, and lifestyle parameters. Eating pattern and eating habits were determined by eating habits questionnaires. A total of 266 LSG surgery candidates (71.4 % female) with an average age of 40.7 ± 10.9 years and pre-surgery BMI of 42.4 ± 4.8 kg/m(2) were studied. More than half of the patients have family history of obesity and their onset of obesity was before the age of 18 years (54.5 and 57.9 %, respectively). Most of the patients reported on poor eating habits and sedentary lifestyle: 65.1 % do not eat regular meals, 70.3 % skip over breakfast, 61.9 % presented loss of control eating, 45 % frequently consume sweets, and 80.1 % were classified as none active. There were no differences in eating patterns or lifestyle parameters between genders. High occurrence of unhealthy eating habits and a non-active lifestyle were detected in morbid obese candidates for LSG surgery. More efforts should be directed towards nutritional and lifestyle education prior to the surgery.

    No prospective study on the long-term effects of gastric resection on gastrointestinal hormonal changes in patients with normal body weight has been reported. The aim of this study was to evaluate the 1-year effect of subtotal gastrectomy on ghrelin and peptide YY (PYY)(3-36) levels. Eighteen patients with early gastric cancer underwent subtotal gastrectomy with Billroth I reconstruction. We assessed appetite, food intake, body composition, and ghrelin and PYY(3-36) levels preoperatively and 1 year after surgery. There were no significant difference in the preoperative daily food intake and 1 year after subtotal gastrectomy. Weight loss occurred in all study subjects; 11.7% (n=2), 55.5% (n=10) and 33.3% (n=6) of the patients lost <5%, 5-10% and >10% of their preoperative body weight, respectively. Body mass index, waist circumference and body fat significantly decreased 1 year after subtotal gastrectomy. There were no significant differences in the appetite visual analogue scale preoperatively and 1 year after subtotal gastrectomy. The plasma ghrelin concentration decreased significantly (P=0.006), whereas PYY(3-36) did not show a significant change 1 year after subtotal gastrectomy. Ghrelin levels and body fat decreased significantly, whereas PYY(3-36) levels as well as appetite and food intake did not change significantly 1 year after subtotal gastrectomy with normal body weight. These findings suggest that decreased ghrelin might contribute directly to reduced body fat.

    With increased utilization of data within their operational and strategic processes, enterprises need to ensure data quality and accuracy. Data curation is a process that can ensure the quality of data and its fitness for use. Traditional approaches to curation are struggling with increased data volumes, and near real-time demands for curated data. In response, curation teams have turned to community crowd-sourcing and semi-automatedmetadata tools for assistance. This chapter provides an overview of data curation, discusses the business motivations for curating data and investigates the role of community-based data curation, focusing on internal communities and pre-competitive data collaborations. The chapter is supported by case studies from Wikipedia, The New York Times, Thomson Reuters, Protein Data Bank and ChemSpider upon which best practices for both social and technical aspects of community-driven data curation are described.

    The description of the specific processes and artifacts that led to the creation of a data product provide a detailed picture of data provenance in the form of a workflow. The Site-Based Data Curation project, hosted by the Center for Informatics Research in Science and Scholarship at the University of Illinois, has been investigating how workflows can be used in developing curation processes and policies that move curation "upstream" in the research process. The team has documented an individual workflow for geobiology data collected during a single field trip to Yellowstone National Park. This specific workflow suggests a generalized three-part process for field data collection that comprises three distinct elements: a Planning Stage, a Fieldwork Stage, and a Processing and Analysis Stage. Beyond supplying an account of data provenance, the workflow has allowed the team to identify 1) points of intervention for curation processes and 2) data products that are likely candidates for sharing or deposit. Although these objects may be viewed by individual researchers as 'intermediate' data products, discussions with geobiology researchers have suggested that with appropriate packaging and description they may serve as valuable observational data for other researchers. Curation interventions may include the introduction of regularized data formats during the planning process, data description procedures, the identification and use of established controlled vocabularies, and data quality and validation procedures. We propose a poster that shows the individual workflow and our generalization into a three-stage process. We plan to discuss with attendees how well the three-stage view applies to other types of field-based research, likely points of intervention, and what kinds of interventions are appropriate and feasible in the example workflow.

    Motivated by the high cost of human curation of biological databases, there is an increasing interest in using computational approaches to assist human curators and accelerate the manual curation process. Towards the goal of cataloging drug indications from FDA drug labels, we recently developed LabeledIn, a human-curated drug indication resource for 250 clinical drugs. Its development required over 40 h of human effort across 20 weeks, despite using well-defined annotation guidelines. In this study, we aim to investigate the feasibility of scaling drug indication annotation through a crowdsourcing technique where an unknown network of workers can be recruited through the technical environment of Amazon Mechanical Turk (MTurk). To translate the expert-curation task of cataloging indications into human intelligence tasks (HITs) suitable for the average workers on MTurk, we first simplify the complex task such that each HIT only involves a worker making a binary judgment of whether a highlighted disease, in context of a given drug label, is an indication. In addition, this study is novel in the crowdsourcing interface design where the annotation guidelines are encoded into user options. For evaluation, we assess the ability of our proposed method to achieve high-quality annotations in a time-efficient and cost-effective manner. We posted over 3000 HITs drawn from 706 drug labels on MTurk. Within 8 h of posting, we collected 18 775 judgments from 74 workers, and achieved an aggregated accuracy of 96% on 450 control HITs (where gold-standard answers are known), at a cost of $1.75 per drug label. On the basis of these results, we conclude that our crowdsourcing approach not only results in significant cost and time saving, but also leads to accuracy comparable to that of domain experts.

    Abstract To evaluate the clinicopathological characteristics and factors that lead to residual tumors in patients who underwent additional gastrectomy for incomplete endoscopic resection (ER) for early gastric cancer (EGC). Between 2003 and 2013, the medical records of patients underwent additional gastrectomy after incomplete ER were retrospectively reviewed. Those diagnosed with the presence of histologic residual tumor in specimens obtained by gastrectomy were assigned to the residual tumor (RT) group (n = 47); those diagnosed with the absence of histologic residual tumor were assigned to the nonresidual tumor (NRT) group (n = 33). In the multivariate analysis, endoscopic piecemeal resection, Helicobacter pylori infection, large tumor size (>2 cm), and both (lateral and vertical) marginal involvement were independent factors of the presence of residual tumor in additional gastrectomy after incomplete resection ER for EGC and the rates of independent factors were significantly higher in the RT group than in the NRT group (P < 0.05). Before ER, preexamination to accurately determine the GC invasion depth and the presence of LN metastasis is very important. During ER, surgeons should attempt to perform en bloc resection and to resect the mucous membrane with adequate safety margins to prevent tumor invasion into the lateral and vertical margins.

    OBJECTIVE: Total gastrectomy often results in postgastrectomy bone disease with decreased bone mass and increased fracture risk. To further elucidate the mechanisms of postgastrectomy bone disease, the authors investigated calcium metabolism and bone mineral density after total gastrectomy in pigs. SUMMARY BACKGROUND DATA: Postgastrectomy bone disease can present as osteomalacia, osteoporosis in excess of normal aging, or a combination of both. The underlying mechanisms are insufficiently understood and need further investigation. METHODS: Growing minipigs were gastrectomized and compared with fed-matched, sham-operated control p gs for 1 year. Calcium absorption, serum calcium, parathyroid hormone, 25-(OH)-vitamin D, 1,25-(OH)2-vitamin D, alkaline phosphatase, and computed tomography bone mineral density were measured in three monthly intervals. RESULTS: Total gastrectomy resulted in impaired calcium absorption, reduced serum calcium and 25-(OH)-vitamin D, increased parathyroid hormone and 1,25-(OH)2-vitamin, and reduced bone mineral density compared with fed-matched, sham-operated control pigs. CONCLUSIONS: The authors data indicate that a reduced serum calcium activates counter-regulatory mechanisms, resulting in calcium mobilization from the bone. Possibly, calcium and vitamin D supplementation after total gastrectomy might prevent postgastrectomy bone mass loss. PMID:9065295

    Background/Aims This study aimed to investigate the prevalence and characteristics of small intestinal bacterial overgrowth (SIBO) in patients undergoing abdominal surgeries, such as gastrectomy, cholecystectomy, and hysterectomy. Methods One hundred seventy-one patients with surgery (50 hysterectomy, 14 gastrectomy, and 107 cholecystectomy), 665 patients with functional gastrointestinal disease (FGID) and 30 healthy controls undergoing a hydrogen (H2)-methane (CH4) glucose breath test (GBT) were reviewed. Results GBT positivity (+) was significantly different among the surgical patients (43.9%), FGID patients (31.9%), and controls (13.3%) (p<0.01). With respect to the patients, 65 (38.0%), four (2.3%), and six (3.5%) surgical patients and 150 (22.6%), 30 (4.5%), and 32 (4.8%) FGID patients were in the GBT (H2)+, (CH4)+ and (mixed)+ groups, respectively (p<0.01). The gastrectomy group had a significantly increased preference in GBT+ (71.4% vs 42.0% or 41.1%, respectively) and GBT (H2)+ (64.3% vs 32.0% or 37.4%, respectively) compared with the hysterectomy or cholecystectomy groups (p<0.01). During GBT, the total H2 was significantly increased in the gastrectomy group compared with the other groups. Conclusions SIBO producing H2 is common in abdominal surgical patients. Different features for GBT+ may be a result of the types of abdominal surgery. PMID:27965476

    Background: There is no advantage in maintaining patients on oral fasting after gastrointestinal elective resection. The early feeding up to 48 h can be beneficial, because it reduces infectious complications and hospital stay. Aim: Evaluate the evolution and tolerance of early oral diet in postoperative period after gastrectomy for gastric cancer. Methods: Anthropometric assessment was performed on the day of surgery, weight, height, body mass index and weight loss were measured. Acceptance of diet was evaluated as food intake (amount accepted) and gastrointestinal symptoms such as nausea, vomiting, constipation, diarrhea, abdominal distension, postoperative complications and hospital stay. Results: The sample consisted of 23 patients, 17 with partial gastrectomy and six with total gastrectomy. In the assessment of nutritional status 9% were malnourished, 54.5% normal weight, 9% overweight and 27.2% obese, but 54% had weight loss. There was good acceptance of the diet in 96,9% of the sample. Nausea and abdominal distension were present in 4,3% and 65.2% constipation. Surgical complications according to the Clavien scalle, 13% had grade V, 4.3% grade IIIA, 8.7% grade I and 73% did not have complications. The length of hospital stay was 5±2.2 days. Conclusion: Early postoperative re-feeding in total and partial gastrectomy was well tolerated by patients. PMID:26537147

    Esophageal reconstruction with colon interposition is an alternative solution for the esophageal cancer patients who have partial gastrectomy. The aim of this study was to investigate the therapeutic effects of colon interposition among the esophageal carcinoma patients with partial gastrectomy. Under institutional review board approval, 32 esophageal carcinoma patients with a history of partial gastrectomy were included in this study. All the patients had been diagnosed and confirmed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma by histopathological examination. Surgical approaches, complications and therapeutic results were analyzed in the current study. Thirty-two esophageal carcinoma patients (29 men, 3 women, median age 63.2 years) were included in this study. Isoperistaltic colon interposition was carried out on 14 patients; their 1-year and 2-year survival rate was 92.9% and 78.6%, respectively. Antiperistaltic colon interposition was carried out on 18 patients; their 1-year and 2-year survival rate was 88.9% and 77.8%, respectively. In which, cervical anastomotic leakage was observed on six patients. Colon interposition is an ideal surgical approach for the esophageal carcinoma patients who had partial gastrectomy. Isoperistaltic colon interposition is preferred, but antiperistaltic colon interposition has the advantage that a longer colon can be used.

    Laparoscopic sleeve gastrectomy (LSG) has gained significant popularity in the USA, and consequently resulted in patients experiencing new-onset gastroesophageal reflux disease (GERD) following this bariatric procedure. Patients with GERD refractory to medical therapy present a more challenging situation limiting the surgical options to further treat the de novo GERD symptoms since the gastric fundus to perform a fundoplication is no longer an option. The aim of this study is to determine if the LINX® magnetic sphincter augmentation system is a safe and effective option for patients with new gastroesophageal reflux disease following laparoscopic sleeve gastrectomy. This study was conducted at the University Medical Center. This is a retrospective review of seven consecutive patients who had a laparoscopic LINX® magnetic sphincter device placement for patients with refractory gastroesophageal reflux disease after laparoscopic sleeve gastrectomy between July 2014 and April 2015. All patients were noted to have self-reported greatly improved gastroesophageal reflux symptoms 2-4 weeks after their procedure. They were all noted to have statistically significant improved severity and frequency of their reflux, regurgitation, epigastric pain, sensation of fullness, dysphagia, and cough symptoms in their postoperative GERD symptoms compared with their preoperative evaluation. This is the first reported pilot case series, illustrating that the LINX® device is a safe and effective option in patients with de novo refractory gastroesophageal reflux disease after a laparoscopic sleeve gastrectomy despite appropriate weight loss.

However, this is not a popular procedure primarily because of the technical difficulties involved in achieving consistent intracorporeal esophagojejunostomy. At Seoul National University Bundang Hospital, we recently introduced a simple, easy-to-use, low-profile laparoscopic manual scope holder that enables the maintenance of a stable field of view, the most demanding condition in single-port gastrectomy. In this technical report, we describe in detail the world's first solo single-incision laparoscopic total gastrectomy with D1+ lymph node dissection and intracorporeal esophagojejunostomy for proximal early gastric cancer.

    To determine the incidence of bilateral distal biceps tendon ruptures. A retrospective review of 321 patients who underwent operative repair of a distal biceps tendon rupture between 1988 and 2010 identified 26 patients with bilateral ruptures. We recorded patient age, mechanism of injury, time between symptom onset before the first surgery and subsequent contralateral symptoms, and time between surgeries. Twenty-two bilateral ruptures were confirmed intra-operatively, 3 by MRI, and 1 was lost to follow up. A total of 23 bilateral ruptures (92%) occurred in men. The average age at the initial rupture was 44 years (range, 29-74 y). The average age at subsequent rupture was 48 years (range, 36-79 y). Excluding the 2 women (age 72 and 79 y), the average age at the initial rupture was 42 years and the average age at subsequent rupture was 46 years. The average interval between ruptures was 4.1 years (range, 0.8-13.9 y). The initial rupture occurred in the dominant extremity in 12 cases (50%) and in the nondominant extremity in 10 cases (42%); in 3 patients (8%) the dominance was not documented or ambidextrous. Thirty-three percent were heavy laborers, 3 patients had a smoking history, and 1 patient reported a history of steroid use. Twenty-two patients (88%) had the second side repaired, where we noted that 12 (55%) of the second tendon ruptures were partial tears. The 8% cumulative incidence of bilateral biceps tendon ruptures in a consecutive series of biceps tendon repairs may be higher because not all patients were contacted, which introduced a sampling bias. This 8% rate is markedly higher than the reported rate of 1.2 per 100,000 for an isolated distal biceps tendon rupture. This implies that patients with a distal biceps tendon rupture are at risk for a rupture on the contralateral side. Prognostic III. Copyright © 2012 American Society for Surgery of the Hand.

    Laparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy. A prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study. There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series. Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    There has been a recent increase in the use of totally laparoscopic total gastrectomy (TLTG) for gastric cancer. However, there is no scientific evidence to determine which esophagojejunostomy (EJS) technique is the best. In addition, both short- and long-term oncological results of TLTG are inconsistent. We reviewed 25 articles about TLTG for gastric cancer in which at least 10 cases were included. We analyzed the short-term results, relationships between EJS techniques and complications, long-term oncological results, and comparative study results of TLTG. TLTG was performed in a total of 1170 patients. The mortality rate was 0.7%, and the short-term results were satisfactory. Regarding EJS techniques and complications, circular staplers (CSs) methods were significantly associated with leakage (4.7% vs. 1.1%, p < 0.001) and stenosis (8.3% vs. 1.8%, p < 0.001) of the EJS as compared with the linear stapler method. The long-term oncological prognosis was acceptable in patients with early gastric cancers and without metastases to lymph nodes. Although TLTG tended to increase surgical time compared with open total gastrectomy and laparoscopy-assisted total gastrectomy, it reduced intraoperative blood loss and was expected to shorten postoperative hospital stay. TLTG is found to be safer and more feasible than open total gastrectomy and laparoscopy-assisted total gastrectomy. At present, there is no evidence to encourage performing TLTG for patients with advanced gastric cancer from the viewpoint of long-term oncological prognosis. Although the current major EJS techniques are CS and linear stapler methods, in this review, CS methods are significantly associated with leakage and stenosis of the EJS.

    Laparoscopic sleeve gastrectomy is gaining popularity in the US; however, there has been no study examining the use of sleeve gastrectomy at a national level and its impact on the use of other bariatric operations. The aim of this study was to examine contemporary changes in use and outcomes of bariatric surgery performed at academic medical centers. Using ICD-9 diagnosis and procedure codes, clinical data obtained from the University HealthSystem Consortium database for all bariatric procedures performed for the treatment of morbid obesity between October 1, 2008 and September 30, 2012 were reviewed. Quartile trends in use for the 3 most commonly performed bariatric operations were examined, and a comparison of perioperative outcomes between procedures was performed within a subset of patients with minor severity of illness. A total of 60,738 bariatric procedures were examined. In 2008, the makeup of bariatric surgery consisted primarily of gastric bypass (66.8% laparoscopic, 8.6% open), followed by laparoscopic gastric banding (23.8%). In 2012, there was a precipitous increase in use of laparoscopic sleeve gastrectomy (36.3 %), with a concurrent reduction in the use of laparoscopic (56.4%) and open (3.2%) gastric bypass, and a major reduction in laparoscopic gastric banding (4.1%). The length of hospital stay, in-hospital morbidity and mortality, and costs for laparoscopic sleeve gastrectomy were found to be between those of laparoscopic gastric banding and laparoscopic gastric bypass. Within the context of academic medical centers, there has been a recent change in the makeup of bariatric surgery. There has been an increase in the use of laparoscopic sleeve gastrectomy, which has had an impact primarily on reducing the use of laparoscopic adjustable gastric banding.

    Neoadjuvant chemotherapy (NAC) has been widely adopted for patients with advanced gastric cancer; however, the safety of gastrectomy with D2 lymphadenectomy followed by NAC has not yet been evaluated. We retrospectively analyzed the influence of NAC on morbidity and mortality after gastrectomy in patients with advanced gastric cancer. A series of 364 patients with advanced gastric cancer who underwent gastrectomy without pancreatectomy between January 2008 and December 2010 at eight hospitals registered to the Yokohama Clinical Oncology Group were studied retrospectively. There were 330 patients who underwent surgical treatment immediately after diagnosis (surgery alone group) and 34 patients (NAC group) who first received NAC and then underwent surgical resection. Although there were no significant differences in the morbidity rate between the two groups, postoperative pancreatic fistula was more often observed in NAC patients than in patients of the group treated with surgery alone [5 cases (14.7%) vs. 11 cases (3.3%); p=0.011]. In the univariate analysis, NAC (p=0.029), bursectomy (p<0.001) and operative bleeding (≥300 ml, p=0.002), were significantly correlated with postoperative pancreatic fistula, and NAC [odds ratio (OR)=4.901, 95% confidence interval (CI)=1.455-16.67; p=0.010] and bursectomy (OR=11.2, 95% CI=3.460-37.04; p<0.001) were independent risk factors for postoperative pancreatic fistula by multivariate analysis. The incidence of postoperative pancreatic fistula was 40.0% among patients who underwent gastrectomy with bursectomy followed by NAC. The incidence of pancreatic fistula in patients treated with NAC and bursectomy was significantly higher than that in other patients. Bursectomy may be discouraged for the prevention of pancreatic fistula from gastrectomy following NAC. Copyright© 2016 International Institute of Anticancer Research (Dr. John G.

    AIM: To evaluate the implementation of a clinical pathway and identify clinical factors affecting the clinical pathway for laparoscopic gastrectomy. METHODS: A standardized clinical pathway for gastric cancer (GC) patients was developed in 2001 by the GC surgery team at the Asan Medical Center. We reviewed the collected data of 4800 consecutive patients treated using the clinical pathway following laparoscopic gastrectomy with lymph node dissection for GC involving intracorporeal and extracorporeal anastomosis. The patients were treated between August 2004 and October 2013 in a single institution. To evaluate the rate of completion and risk factors affecting dropout from the clinical pathway, we used a multivariate logistic regression analysis. RESULTS: The overall completion rate of the clinical pathway for laparoscopic gastrectomy was 84.1% (n = 4038). In the comparison between groups of intracorporeal anastomosis and extracorporeal anastomosis patients, the completion rates were 83.88% (n = 1740) and 84.36% (n = 2071), respectively, showing no statistically significant difference. The main reasons for dropping out were postoperative complications (n = 463, 9.7%) and the need for patient observation (n = 299, 6.2%). Among the discharged patients treated using the clinical pathway, the number of patients who were readmitted within 30 d due to postoperative complications was 54 (1.1%). In a multivariate analysis, the intraoperative events (OR = 2.558) were the most predictable risk factors for dropping out of the clinical pathway. Additionally, being male (OR = 1.459), advanced age (OR = 1.727), total gastrectomy (OR = 2.444), combined operation (OR = 1.731), and ASA score (OR = 1.889) were significant risk factors affecting the dropout rate from the clinical pathway. CONCLUSION: Laparoscopic gastrectomy appears to be a good indication for the application of a clinical pathway. For successful application, patients with risk factors should be managed carefully.

    Laparoscopic sleeve gastrectomy (LSG) has been performed for morbid obesity in the past 10 years. LSG was originally intended as a first-stage procedure in high-risk patients but has become a stand-alone operation for many bariatric surgeons. Ongoing review is necessary regarding the durability of the weight loss, complications, and need for second-stage operations. The first International Summit for LSG was held in October 2007, the second in March 2009, and this third in December 2010. There were presentations by experts, and, to provide a consensus, a questionnaire was completed by 88 attendees who had >1 year (mean 3.6 ± 1.5, range 1-8) of experience with LSG. The results of the questionnaire were based on 19,605 LSGs performed within 3.6 ± 1.5 years (228.8 ± 275.0 LSGs/surgeon). LSG had been intended as the sole operation in 86.4% of the cases; in these, a second-second stage became necessary in 2.2%. LSG was completed laparoscopically in 99.7% of the cases. The mean percentage of excess weight loss at 1, 2, 3, 4, and 5 years was 62.7%, 64.7%, 64.0%, 57.3%, and 60.0%, respectively. The bougie size was 28-60F (mean 36F, 70% blunt tip). Resection began 1.5-7.0 cm (mean 4.8) proximal to the pylorus. Of the surgeons, 67.1% reinforced the staple line, 57% with buttress material and 43% with oversewing. The respondents excised an estimated 92.9% ± 8.0% (median 95.0%) of fundus (i.e., a tiny portion is maintained lateral to the angle of His). A drain is left by 57.6%, usually closed suction. High leaks occurred in 1.3% of cases (range 0-10%); lower leaks occurred in .5%. Intraluminal bleeding occurred in 2.0% of cases. The mortality rate was .1% ± .3%. According to the questionnaire, presentations, and debates, the weight loss and improvement in diabetes appear to be better than with laparoscopic adjustable gastric banding and on par with Roux-en-Y gastric bypass. High leaks are infrequent but problematic. Copyright © 2011 American Society for Metabolic and

    The life-time drinking profiles of Japanese alcoholics have shown that gastrectomy increases susceptibility to alcoholism. We investigated the trends in gastrectomy and alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) genotypes and their interactions in alcoholics. This survey was conducted on 4879 Japanese alcoholic men 40 years of age or older who underwent routine gastrointestinal endoscopic screening during the period 1996-2010. ADH1B/ALDH2 genotyping was performed in 3702 patients. A history of gastrectomy was found in 508 (10.4%) patients. The reason for the gastrectomy was peptic ulcer in 317 patients and gastric cancer in 187 patients. The frequency of gastrectomy had gradually decreased from 13.3% in 1996-2000 to 10.5% in 2001-2005 and to 7.8% in 2006-2010 (P < 0.0001). ADH1B*1/*1 was less frequent in the gastrectomy group than in the non-gastrectomy group (age-adjusted prevalence: 20.4 vs. 27.6%, P = 0.006). ALDH2 genotype distribution did not differ between the two groups. The frequency of inactive ALDH2*1/*2 heterozygotes increased slightly from 13.0% in 1996-2000 to 14.0% in 2001-2005 and to 15.4% in 2006-2010 (P < 0.08). Two alcoholism-susceptibility genotypes, ADH1B*1/*1 and ALDH2*1/*1, modestly but significantly tended not to occur in the same individual (P = 0.026). The frequency of ADH1B*1/*1 decreased with ascending age groups. The high frequency of history of gastrectomy suggested that gastrectomy is still a risk factor for alcoholism, although the percentage decreased during the period. The alcoholism-susceptibility genotype ADH1B*1/*1 was less frequent in the gastrectomy group, suggesting a competitive gene-gastrectomy interaction for alcoholism. A gene-gene interaction and gene-age interactions regarding the ADH1B genotype were observed.

    A new phenomenon, the inverted or "flipped" classroom, assumes that students are no longer acquiring knowledge exclusively through textbooks or lectures. Instead, they are seeking out the vast amount of free information available to them online (the very essence of open source) to supplement learning gleaned in textbooks and lectures. With so much open-source content available to nursing faculty, it benefits the faculty to use readily available, technologically advanced content. The nurse content curator supports nursing faculty in its use of such content. Even more importantly, the highly paid, time-strapped faculty is not spending an inordinate amount of effort surfing for and evaluating content. The nurse content curator does that work, while the faculty uses its time more effectively to help students vet the truth, make meaning of the content, and learn to problem-solve.

    Digital data both enable and constrain scientific research. Scientists are enabled by digital data to develop new research methods, utilize new data sources, and investigate new topics, but they also face new data collection, management, and preservation burdens. The current data workforce consists primarily of scientists who receive little formal training in data management and data managers who are typically educated through on-the-job training. The Data Curation Education in Research Centers (DCERC) program is investigating a new model for educating data professionals to contribute to scientific research. DCERC is a collaboration between the University of Illinois at Urbana-Champaign Graduate School of Library and Information Science, the University of Tennessee School of Information Sciences, and the National Center for Atmospheric Research. The program is organized around a foundations course in data curation and provides field experiences in research and data centers for both master's and doctoral students. This presentation will outline the aims and the structure of the DCERC program and discuss results and lessons learned from the first set of summer internships in 2012. Four masters students participated and worked with both data mentors and science mentors, gaining first hand experiences in the issues, methods, and challenges of scientific data curation. They engaged in a diverse set of topics, including climate model metadata, observational data management workflows, and data cleaning, documentation, and ingest processes within a data archive. The students learned current data management practices and challenges while developing expertise and conducting research. They also made important contributions to NCAR data and science teams by evaluating data management workflows and processes, preparing data sets to be archived, and developing recommendations for particular data management activities. The master's student interns will return in summer of 2013

For example, the UniProt protein database, the EcoCyc Escherichia coli database and the Candida Genome Database (CGD) are all based on biocuration. Biological databases are used extensively by life science researchers, as online encyclopedias, as aids in the interpretation of new experimental data and as golden standards for the development of new bioinformatics algorithms. Although manual curation has been assumed to be highly accurate, we are aware of only one previous study of biocuration accuracy. We assessed the accuracy of EcoCyc and CGD by manually selecting curated assertions within randomly chosen EcoCyc and CGD gene pages and by then validating that the data found in the referenced publications supported those assertions. A database assertion is considered to be in error if that assertion could not be found in the publication cited for that assertion. We identified 10 errors in the 633 facts that we validated across the two databases, for an overall error rate of 1.58%, and individual error rates of 1.82% for CGD and 1.40% for EcoCyc. These data suggest that manual curation of the experimental literature by Ph.D-level scientists is highly accurate. Database URL: http://ecocyc.org/, http://www.candidagenome.org// PMID:24923819

    Background Laparoscopic gastrectomy requires a reverse-Trendelenburg position and prolonged pneumoperitoneum and it could cause significant changes in cerebral homeostasis and lead to cognitive dysfunction. We compared changes in regional cerebral oxygen saturation (rSO2), early postoperative cognitive function and hemodynamic variables in patients undergoing laparoscopic gastrectomy with those patients that underwent conventional open gastrectomy. Methods Sixty patients were enrolled in this study and the patients were distributed to receive either laparoscopic gastrectomy (laparoscopy group, n = 30) or open conventional gastrectomy (open group, n = 30). rSO2, end-tidal carbon dioxide tension, hemodynamic variables and arterial blood gas analysis were monitored during the operation. The enrolled patients underwent the mini-mental state examination 1 day before and 5 days after surgery for evaluation of early postoperative cognitive function. Results Compared to baseline value, rSO2 and end-tidal carbon dioxide tension increased significantly in the laparoscopy group after pneumoperitoneum, whereas no change was observed in the open group. No patient experienced cerebral oxygen desaturation or postoperative cognitive dysfunction. Changes in mean arterial pressure over time were significantly different between the groups (P < 0.001). Conclusions Both laparoscopic and open gastrectomy did not induce cerebral desaturation or early postoperative cognitive dysfunction in patients under desflurane anesthesia. However, rSO2 values during surgery favoured laparoscopic surgery, which was possibly related to increased cerebral blood flow due to increased carbon dioxide tension and the effect of a reverse Trendelenburg position.

  2. Distal realignment (tibial tuberosity transfer).

    Although tibial tuberosity (TT) transfer has for many years been the basis of many protocols for the management of patellar instability, the role of pure medial transfer in particular appears to be declining. In contrast, the greater recognition of the importance of patella alta as a predisposing factor to recurrent patellar dislocation has resulted in a resurgence in the popularity of distal TT transfer. When TT transfer is performed, the direction and amount of transfer is based on the patellar height and the lateralization of the TT relative to the trochlear groove. Patellar height is best assessed on a lateral radiograph with the knee in flexion using a ratio that uses the articular surface of the patella in relation to the height above the tibia. Assessment of lateralization of the TT relative to the trochlear groove can be made using either computed tomography or magnetic resonance imaging scans.

    Gastroesophageal reflux disease is a common comorbid medical condition of obesity. Laparoscopic sleeve gastrectomy has been associated with de novo and worsening GERD following surgery. For this reason, patients who suffer from GERD and are considering bariatric surgery are often counseled to undergo gastric bypass. Given this practice, we sought to determine acid reduction medication (ARM) utilization in bariatric surgical patients who undergo one of these procedures prior to surgery and at 1 year following surgery. A retrospective review of prospectively maintained data on patients to undergo gastric bypass or sleeve gastrectomy between November 2012 and December 2014 was conducted after IRB approval. ARM utilization and Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQL) scores [range 0 (no symptoms)-50 (severe GERD)] were compared prior to surgery and at 1 year postoperatively. 334 patients underwent an eligible procedure in the study interval. 147 patients (44 %) had data on both preoperative and 1 year postoperative ARM use (93 gastric bypass and 54 sleeve gastrectomy). ARM utilization prior to surgery in gastric bypass patients did not reach statistical significance when compared to sleeve gastrectomy (40.9 vs. 26 %, p = 0.07). GERD-HRQL scores were greater prior to surgery in gastric bypass patients (GERD-HRQL 8.2 vs. 1.9; p < 0.01). At 12 months postoperatively, sleeve gastrectomy patients had a significantly higher rate of overall ARM use (48.1 vs. 16.1 %, p < 0.01), new ARM use (35 vs. 7.3 %, p < 0.01), and persistent ARM use (78.6 vs. 21.9 %, p < 0.01) when compared to gastric bypass patients. GERD-HRQL scores were similar overall at 12 months postoperatively (4.4 bypass vs. 4.8 sleeve; p = 0.72). Laparoscopic sleeve gastrectomy is associated with a significantly increased likelihood that acid reduction medications will be necessary for GERD symptom control 12 months postoperatively when compared to gastric

    The aim of the study was to determine one-year effects of total gastrectomy on plasma silicon and free amino acid concentrations in patients and evaluate changes of volumetric bone mineral density (vBMD) in lumbar spine. Eight patients were enrolled to the control (CTR) group. Six patients subjected to total gastrectomy (GX group) were included to the experimental group. vBMD in trabecular and cortical bone was measured in lumbar vertebrae at baseline (before surgery) and one year later using quantitative computed tomography. Plasma concentrations of silicon and free amino acids were determined at baseline and one year later using photometric method and ion-exchange chromatography. Body weights within CTR and GX groups were not different after one-year follow-up when compared to the baseline values (P > 0.05). An average annual decrease of vBMD in the trabecular bone in the gastrectomized patients reached 15.0% in lumbar spine and was significantly different in comparison to the percentage changes observed in CTR group (P = 0.02). One-year percentage change of vBMD in the cortical bone in L1 and L2 has shown significantly decreased values by 10.5 and 9.1% in the GX group when compared to the percentage change observed in the controls (P < 0.05). Plasma concentration of adipic acid was significantly higher by 101.6% one year after total gastrectomy procedure in the patients when compared to the baseline value (P = 0.01). Plasma concentration of silicon was significantly lowered by 26.7% one year after the total gastrectomy when compared to the baseline value (P = 0.009). Total gastrectomy in patients has induced severe osteoporotic changes in lumbar spine within one-year period. The observed osteoporotic changes were associated with decreased plasma concentration of silicon indicating importance of exocrine and endocrine functions of stomach for silicon homeostasis maintenance. Gastrectomy-induced bone loss was not related to decreased amino acid

    The need for data curation is being recognized in numerous institutional settings as national research funding agencies extend data archiving mandates to cover more types of research grants. Data curation, however, is not only a practical challenge. It presents many conceptual and theoretical challenges that must be investigated to design appropriate technical systems, social practices and institutions, policies, and services. This presentation reports on outcomes from an investigation of research problems in data curation conducted as part of the Data Curation Education in Research Centers (DCERC) program. DCERC is developing a new model for educating data professionals to contribute to scientific research. The program is organized around foundational courses and field experiences in research and data centers for both master's and doctoral students. The initiative is led by the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign, in collaboration with the School of Information Sciences at the University of Tennessee, and library and data professionals at the National Center for Atmospheric Research (NCAR). At the doctoral level DCERC is educating future faculty and researchers in data curation and establishing a research agenda to advance the field. The doctoral seminar, Research Problems in Data Curation, was developed and taught in 2012 by the DCERC principal investigator and two doctoral fellows at the University of Illinois. It was designed to define the problem space of data curation, examine relevant concepts and theories related to both technical and social perspectives, and articulate research questions that are either unexplored or under theorized in the current literature. There was a particular emphasis on the Earth and environmental sciences, with guest speakers brought in from NCAR, National Snow and Ice Data Center (NSIDC), and Rensselaer Polytechnic Institute.

    The aim of this study was to investigate the feasibility of sentinel node mapping using a fluorescent dye and visible light in patients with gastric cancer. Recently, fluorescent imaging technology offers improved visibility with the possibility of better sensitivity or accuracy in sentinel node mapping. Twenty patients with early gastric cancer, for whom laparoscopic distal gastrectomy with standard lymphadenectomy had been planned, were enrolled in this study. Before lymphadenectomy, the patients received a gastrofiberoscopic peritumoral injection of fluorescein solution. The sentinel basin was investigated via laparoscopic fluorescent imaging under blue light (wavelength of 440-490 nm) emitted from an LED curing light. The detection rate and lymph node status were analyzed in the enrolled patients. In addition, short-term clinical outcomes were also investigated. No hypersensitivity to the dye was identified in any enrolled patients. Sentinel nodes were detected in 19 of 20 enrolled patients (95.0%), and metastatic lymph nodes were found in 2 patients. The latter lymph nodes belonged to the sentinel basin of each patient. Meanwhile, 1 patient (5.0%) experienced a postoperative complication that was unrelated to sentinel node mapping. No mortality was recorded among enrolled cases. Sentinel node mapping with visible light fluorescence was a feasible method for visualizing sentinel nodes in patients with early gastric cancer. In addition, this method is advantageous in terms of visualizing the concrete relationship between the sentinel nodes and surrounding structures.

    In a multicentric trial the postoperative mortality and the 5-year survival of elective total gastrectomy (TG) was compared with subtotal gastrectomy (SG) for adenocarcinoma of the antrum operated on with intent of cure. Two hundred and one patients were included in the study; 32 were excluded after pathologic examination (linitis plastica, superficial cancer, lymphoma). One hundred sixty-nine patients remained for analysis, with 93 undergoing TG and 76 undergoing SG. Elective TG did not increase postoperative mortality (1.3%) compared with SG (3.2%). There was no difference in the 5-year survival rate (48%). Analysis of survival showed no difference in the two techniques when related to nodal involvement and serosal extension. It is concluded that both TG and SG can be performed safely in patients with adenocarcinoma of the antrum; however TG did not increase the survival rate. PMID:2644898

    The aim of this study was to introduce and examine a modified mechanical end-to-side esophagogastrostomy method ("reverse-Tornado" anastomosis) in laparoscopy-assisted proximal gastrectomy. Five patients with gastric cancer who underwent laparoscopy-assisted proximal gastrectomy were analyzed retrospectively. Esophagogastrostomy in the anterior wall was performed in three patients, and esophagogastrostomy in the posterior wall was performed in two patients. Clinicopathological features, operative outcomes (operative time, operative blood loss), and postoperative outcomes (complications, postoperative hospital stay, reflux esophagitis) were evaluated. Operative time was normal (278 min). There was no marked operative blood loss, postoperative complications, prolonged hospital stay, or reflux esophagitis. Esophagogastrostomy was completed in a normal time with reverse-Tornado anastomosis. This method can be safe and can enable good postoperative quality of life. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    A 72-year-old man who had undergone a total gastrectomy with a Roux-en-Y esophagojejunostomy for gastric cancer 6 years earlier presented to our hospital with massive hematemesis and melena. Endoscopic examination indicated esophageal varices with cherry-red spots and hemorrhage arising from beyond the anastomosis. Abdominal contrast-enhanced computed tomography and angiography revealed a dilated vein in the elevated jejunal limb supplying the varices. Percutaneous trans-hepatic obliteration (PTO) of the varices through the jejunal vein was performed using microcoils, ethanolamine oleate, and gelatin sponge cubes. Ten days after the procedure, endoscopic examination revealed reduction and thrombosis of the varices. We consider PTO to be an effective alternative method for treating ruptured esophagojejunal varices after total gastrectomy.

    In advanced gastric cancer, laparoscopic management has been associated with trocar-site recurrence, even though laparoscopy-assisted gastrectomies have reported positive results to treat early-stage gastric cancer in the world. There are no reports of port-site recurrence after laparoscopic gastrectomy in the literature. In this paper, we present a case report of advanced gastric cancer with port-site recurrence 12 month after the initial operation. A wide excision of this recurrence was performed. Otherwise, the evaluation of metastasis in other sites remained negative at 18 months after the original operation. The laparoscopic surgeon should be aware of trocar-site recurrence when dealing with advanced gastric cancer.

    Hiatal hernias after total gastrectomy for advanced gastric cancer are very rare. We review a case of a 44-year-old male who presented with dyspnea and chest pain 2 days after total gastrectomy, lower esophagectomy, and splenectomy with retrocolic Roux-en-Y reconstruction approached by a left thoracoabdominal incision for gastric cancer at the cardia. Plain and cross-sectional imaging identified a large hiatal hernia protruding into the right thorax containing left-sided transverse colon and small intestine. Our patient underwent a laparotomy, and after hernia reduction the hiatal defect was repaired by direct suturing. He experienced anastomotic leakage and right pyothorax, but recovered. The potential cause is discussed here and the published literature on this rare complication is reviewed briefly.

    Although reported in the literature, conventional laparoscopic approach for distal pancreatectomy is still lacking widespread acceptance. This might be due to two-dimensional vision and decreased range of motion to reach and safely dissect this highly vascularized retroperitoneal organ by laparoscopy. However, interest in minimally invasive access is growing ever since and the robotic system could certainly help overcome limitations of the laparoscopic approach in the challenging domain of pancreatic resection, notably in distal pancreatectomy. Robotic distal pancreatectomy with and without spleen preservation has been reported with encouraging outcomes for benign and borderline malignant disease. As a result of upgraded endowristed manipulation and three-dimensional visualization, improved outcome might be expected with the launch of the robotic system in the procedure of distal pancreatectomy. Our aim was thus to extensively review the current literature of robot-assisted surgery for distal pancreatectomy and to evaluate advantages and possible limitations of the robotic approach.

    Background A subset of patients with diffuse gastric cancer harbor deleterious cancer-causing germline mutations in the E-cadherin (CDH1) gene, which predisposes to the autosomal dominantly inherited hereditary diffuse gastric cancer (HDGC) syndrome. These mutations are associated with a 70% life-time risk for diffuse gastric cancer (DGC) and, in addition, a 40% risk for lobular breast cancer in females. Management options for unaffected mutation carriers include prophylactic total gastrectomy. Methods Four HDGC pedigrees from a cohort of 56 CDH1 mutation-positive families have been subjected to further analysis. Cancer diagnoses, whenever possible, were verified with pathology reports and/or slides/tissue block review. Genetic counseling for family members covered HDGC’s natural history, the pros and cons of mutation testing, the lack of effective screening procedures available to CDH1 mutation-positive individuals, and the option for them of prophylactic total gastrectomy. Results Within these four families, carrier testing for mutations in the CDH1 gene was carried out on 52 individuals, of whom 25 were mutation positive. Prophylactic gastrectomies were performed on a total of 17 individuals from 3 of the families, including 11 first cousins from one of the families. Occult DGC was diagnosed in gastrectomy specimens from 13/17 (76.5%) individuals. During follow-up questioning, each of the mentioned 11 cousins stated that the decision for the prophylactic procedure was the “right one” for them. Conclusions Unaffected mutation carriers from HDGC families face difficult decisions and can best be assisted through education and the interactions with counseling by an informed multidisciplinary team.

    The aims of this study were to determine whether ectopic pacemakers are present after meals in the Roux limbs of dogs after vagotomy and Roux gastrectomy, whether these pacemakers slow gastric emptying of liquids or solids, and whether abolishing the pacemakers with electric pacing might speed any slow emptying that occurs. In six dogs that underwent vagotomy and Roux gastrectomy and in four dogs that underwent vagotomy and Billroth gastrectomy (controls), myoelectric activity of the Roux limb or duodenum was measured during gastric emptying of a 500 kcal mixed meal of 99mTc-labeled cooked egg and 111In-labeled milk. Roux dogs were tested with and without pacing of the Roux limb. Roux dogs showed ectopic pacemaker in the Roux limb that drove the pacesetter potentials of the limb in a reverse, or orad, direction during 57% of the postprandial recordings. Billroth dogs had no ectopic pacemakers (p less than 0.05). Liquids emptied more slowly in Roux dogs (half-life (t1/2) = 121 +/- 15 minutes) than in Billroth dogs (t1/2 = 43 +/- 9 minutes; p less than 0.05), but solids emptied similarly in both groups of dogs (t1/2 approximately 8 hours). Pacing the Roux limb abolished the ectopic pacemakers, restored the slow emptying of liquids to the more rapid rate found in the Billroth dogs (t1/2: paced Roux, 72 +/- 15 minutes; Billroth, 43 +/- 9 minutes; p greater than 0.05) and did not change emptying of solids. The conclusion was that ectopic pacemakers present in the Roux limb after vagotomy and Roux gastrectomy drove the limb in a reverse direction and slowed emptying of liquids after the operation. The defect was corrected by pacing the Roux limb in a forward direction.

    Robot-assisted gastrectomy has been reported as a safe alternative to the conventional laparoscopy or open approach for treating early gastric carcinoma. To date, however, there are a limited number of published reports available in the literature. We assess the current status of robotic surgery in the treatment of gastric cancer, focusing on the technical details and oncological considerations. In gastric surgery, the biggest advantage of robotic surgery is the ease and reproducibility of D2-lymphadenectomy. Reports show that even the intracorporeal digestive restoration is facilitated by use of the robotic approach, particularly following total gastrectomy. Additionally, the accuracy of robotic dissection is confirmed by decreased blood loss, as reported in series comparing robot-assisted with laparoscopic gastrectomy. The learning curve and technical reproducibility also appear to be shorter with robotic surgery and, consequently, robotics can help to standardize and diffuse minimally invasive surgery in the treatment of gastric cancer, even in the later stages. This is important because the application of minimally invasive surgery is limited by the complexity of performing a D2-lymphadenectomy. The potential to reproduce D2-lymphadenectomy, enlarged resections, and complex reconstructions provides robotic surgery with an important role in the therapeutic strategy of advanced gastric cancer. While published reports have shown no significant differences in surgical morbidity, mortality, or oncological adequacy between robot-assisted and conventional laparoscopic gastrectomy, more studies are needed to assess the indications and oncological effectiveness of robotic use in the treatment of gastric carcinoma. Herein, the authors assess the current status of robotic surgery in the treatment of gastric cancer, focusing on the technical details and oncological considerations.

    Background Hospital readmission is gathering increasing attention as a measure of health care quality and a potential cost-saving target. The purpose of this prospective study was to determine risk factors for readmission within 30 days of discharge after gastrectomy for patients with gastric cancer. Methods We conducted a prospective study of patients undergoing radical gastrectomy for gastric cancer from October 2013 to November 2014 in our institution. The incidence, cause and risk factors for 30-day readmission were determined. Results A total of 376 patients were included in our analysis without loss in follow-up. The 30-day readmission rate after radical gastrectomy for gastric cancer was 7.2% (27of 376). The most common cause for readmission included gastrointestinal complications and postoperative infections. On the basis of multivariate logistic regression analysis, preoperative nutritional risk screening 2002 score ≥ 3 was an independent risk factor for 30-day readmission. Factors not associated with a higher readmission rate included a history of a major postoperative complication during the index hospitalization, prolonged primary length of hospital stay after surgery, a history of previous abdominal surgery, advanced age, body mass index, pre-existing cardiopulmonary comorbidities, American Society of Anesthesiology grade, type of resection, extent of node dissection and discharge disposition. Conclusions Readmission within 30 days of discharge after radical gastrectomy for gastric cancer is common. Patients with nutritional risk preoperatively are at high risk for 30-day readmission. Preoperative optimization of nutritional status of patients at nutritional risk may effectively decrease readmission rates. PMID:25915547

    Postoperative intussusception is an unusual clinical entity in adults, and is rarely encountered as a complication following gastric surgery. The most common type after gastric surgery is retrograde jejunogastric intussusception, and jejunojejunal intussusception has been rarely reported. We report a case of anterograde jejunojejunal intussusception after radical subtotal gastrectomy with Billroth II anastomosis in a 38-year-old Korean woman with early gastric cancer, and include a review of the literature on this unusual complication.

    After the failure of sleeve gastrectomy (SG), three options are available as a second intervention: the conversion into a biliopancreatic diversion with duodenal switch, the Roux-en-Y gastric bypass (RYGBP), and more recently, a re-SG consisting in the refashioning of a dilated gastric tube. We describe two different approaches for the conversion. The conversion to RYGBP remains a technically challenging operation but feasible and effective, and it should be reserved to specialized centers.

    The aim of the present study was to assess the curative effects of three surgical approaches for a giant cell tumor (GCT) of the distal radius and ulna. A total of 27 patients with GCT on distal radius and ulnas (7 and 20, respectively), confirmed by biopsy, were treated with individualized treatment regimens, according to the Campanacci's grade system: i) Curettage plus inactivated tumor bed and allogeneic bone graft/bone cement augmentation for Campanacci's grade I GCT of the distal radius and ulna (Group A); ii) simple en bloc resection for Campanacci's grade II and III GCT of the distal ulna (Group B); iii) en bloc resection and reconstruction with non-vascularized fibular autograft/allogeneic bone graft for Campanacci's II and III GCT of the distal radius (Group C). Postoperative recurrence and complications were recorded. The Musculoskeletal Tumor Society Score was used to assess functional results. The mean follow-up time was 25 months (range, 9–125 months). A total of 3 patients exhibited tumor recurrence at 9, 11 and 15 months following surgery (1 case succumbed to pulmonary metastasis at 27 months). Overall, the incidence of the postoperative recurrence of the GCT of the distal ulna and radius were 14.3 (1/7) and 10% (2/20), respectively, with a statistical P-value of 0.762. No statistically significant difference was observed regarding the incidence of the postoperative recurrence, postoperative complications and MSTS results among the three surgical approaches for the GCT on distal ulna and radius (all P>0.05). However, statistically significant differences were noted when the incidence of the postoperative recurrence of curettage (Group A) was compared with that of en bloc resection (Groups B and C) (P=0.024). In conclusion, in order to achieve the best clinical effects for patients with GCT on distal radius and ulna, individualized treatment regimens must be designed according to the different Campanacci's grades and tumor locations.

    Gastrectomy method is known to influence glucose homeostasis. (18)F-fluoro-2-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) images acquired after gastrectomy often reveals newly developed physiological small bowel uptake. We correlated newly developed small bowel FDG uptake and glucose homeostasis in postgastrectomy gastric cancer patients. We retrospectively analyzed 239 patients without diabetes who underwent staging and follow-up FDG PET/CT scanning before and after gastrectomy for gastric cancer. Postoperative small bowel glycolysis was quantified by recording intestinal total lesion glycolysis (TLG). TLG was assessed with regard to surgical method (Billroth I, Billroth II [BII], Roux-en-Y [RY]), fasting glucose decrement (≥10 mg/dL), and other clinical factors. Patients' weight, fasting glucose, cholesterol, TLG, and body fat levels significantly decreased after surgery. The glucose decrement was significantly associated with fasting glucose, surgical methods, total cholesterol, TLG, and total body fat on univariate analysis. Multivariate analysis showed that BII surgery (odds ratio 6.51) and TLG (odds ratio 3.17) were significantly correlated with glucose decrement. High small bowel glycolysis (TLG >42.0 g) correlated with glucose decrement in RY patients. Newly developed small bowel glycolysis on postgastrectomy FDG PET/CT scanning is correlated with a glucose decrement. These findings suggest a potential role of FDG PET/CT scanning in the evaluation of small bowel glycolysis and glucose control. © 2017 by the American Diabetes Association.

    A 45-year-old woman who had undergone total gastrectomy for gastric cancer presented with a history of postprandial hypoglycemic episodes with loss of consciousness after meals. Laboratory findings revealed marked hyperinsulinemia and hypoglycemia after a meal. We first treated the patient with octreotide; however, she was unable to continue the treatment because of adverse effects of the drug, such as nausea and headache. Diazoxide was used next for preventing hyperinsulinemia; however, this was not effective for suppressing the postprandial insulin secretion. Since hypoglycemia following gastrectomy is thought to be caused by rapid delivery of nutrients into the duodenum, we performed a meal tolerance test while varying the timing of administration of miglitol in relation to the meal. Miglitol was administered 30 min before, just before, or both 30 min and just before a meal. In the case of administration just before a meal, insulin secretion was suppressed, although hypoglycemia was not prevented. Administration of the drug 30 min before a meal prevented postprandial hypoglycemia by slowing the increase of the blood glucose and serum insulin levels following the meal to a greater degree than administration just before a meal. Miglitol administration both 30 min and just before a meal caused an even smoother increase in blood glucose and serum insulin levels following the meal. In this report, we propose a new therapeutic approach for reactive hypoglycemia after gastrectomy, namely, administration of miglitol 30 min before meals.

  6. Complications after radical gastrectomy following FOLFOX7 neoadjuvant chemotherapy for gastric cancer

    2011-01-01

    Background This study assessed the postoperative morbidity and mortality occurring in the first 30 days after radical gastrectomy by comparing gastric cancer patients who did or did not receive the FOLFOX7 regimen of neoadjuvant chemotherapy. Methods We completed a retrospective analysis of 377 patients after their radical gastrectomies were performed in our department between 2005 and 2009. Two groups of patients were studied: the SURG group received surgical treatment immediately after diagnosis; the NACT underwent surgery after 2-6 cycles of neoadjuvant chemotherapy. Results There were 267 patients in the SURG group and 110 patients in the NACT group. The NACT group had more proximal tumours (P = 0.000), more total/proximal gastrectomies (P = 0.000) and longer operative time (P = 0.005) than the SURG group. Morbidity was 10.0% in the NACT patients and 17.2% in the SURG patients (P = 0.075). There were two cases of postoperative death, both in the SURG group (P = 1.000). No changes in complications or mortality rate were observed between the SURG and NACT groups. Conclusion The FOLFOX7 neoadjuvant chemotherapy is not associated with increased postoperative morbidity, indicating that the FOLFOX7 neoadjuvant chemotherapy is a safe choice for the treatment of local advanced gastric cancer.

    AIM To show outcomes of our series of patients that underwent a total gastrectomy with a robotic approach and highlight the technical details of a proposed solution for the reconstruction phase. METHODS Data of gastrectomies performed from May 2014 to October 2016, were extracted and analyzed. Basic characteristics of patients, surgical and clinical outcomes were reported. The technique for reconstruction (Parisi Technique) consists on a loop of bowel shifted up antecolic to directly perform the esophago-enteric anastomosis followed by a second loop, measured up to 40 cm starting from the esojejunostomy, fixed to the biliary limb to create an enteroenteric anastomosis. The continuity between the two anastomoses is interrupted just firing a linear stapler, so obtaining the Roux-en-Y by avoiding to interrupt the mesentery. RESULTS Fifty-five patients were considered in the present analysis. Estimated blood loss was 126.55 ± 73 mL, no conversions to open surgery occurred, R0 resections were obtained in all cases. Hospital stay was 5 (3-17) d, no anastomotic leakage occurred. Overall, a fast functional recovery was shown with a median of 3 (3-6) d in starting a solid diet. CONCLUSION Robotic surgery and the adoption of a tailored reconstruction technique have increased the feasibility and safety of a minimally invasive approach for total gastrectomy. The present series of patients shows its implementation in a western center with satisfying short-term outcomes. PMID:28694670

    The reduction in the preferences for sweet and fat containing tastes in obese patients who underwent bariatric surgery was relatively well shown; however, there are only limited data on the changes in the sensitivity of other tastes like sour, salty, and bitter. We investigated the changes in gustatory sensitivity of 52 morbidly obese patients (M/F, 22/30; age range, 19-60 years; BMI range, 32.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. The surgery was performed by the same surgeon using 5 ports technique. Gustatory sensitivity was tested preoperatively and 1 and 3 months after the surgery using standardized Taste Strips test. There was a statistically significant improvement in the taste acuity to sweet, sour, salty, and bitter tastants in morbidly obese patients after the laparoscopic sleeve gastrectomy during the follow-up period of 3 months. Median whole test scores of the patients were increased from 11.5 preoperatively to 14 in the first and third months. In this study, we were able to show the significant improvement in gustatory sensitivity of morbidly obese patients after laparoscopic sleeve gastrectomy for the first time in literature. © The Author(s) 2016.

    To evaluate the feasibility and safety of early removal of nasogastric tube after total gastrectomy for gastric cancer. Data of 142 gastric cancer patients who underwent total gastrectomy from January 2011 to March 2012 were retrospectively collected and analyzed. Early removal ER group n=57 of nasogastric tube was defined as removal within postoperative 48 h, and conventional placement CP group n=85 of nasogastric tube was defined as removal till flatus and less than 300 cc gastric juice drainage. Outcome measures included postoperative temperature, hospital stay length, days to passage of flatus, days to semi-liquid diet, postoperative complications and mortality. No statistically significant difference was found between the ER group and the CP group in postoperative highest temperature p=0,456 the incidence of temperature over 38.5C p=0,772 postoperative hospital stay length p=0,102 and time to flatus p=0,163 There was no death or reoperation in patients of both groups. There were no significant differences in postoperative complications between the two groups 22,8% vs 30,6%, p=0,309 There was no anastomotic leakage, hemorrhage or stenosis. There was a trend of decreased risk of postoperative pneumonia in the ER group 10,5% vs 21,2% despite no significance p=0,097 CONCLUSIONS: The early removal of nasogastric tube within postoperative 48 h after total gastrectomy is feasible and safe in common practice and might also have a potential benefit in preventing postoperative pneumonia.

    Multimodal protocols may enhance postoperative recovery. The aim of this study was to evaluate the influence of a multimodal protocol in the clinical results, insulin resistance, and inflammatory response to trauma in morbidly obese patients undergoing sleeve gastrectomy. The population of the study consisted of morbidly obese patients, who were operated using sleeve gastrectomy, from Cuiaba, MT, Brazil, between April and October 2012. Twenty patients were divided into two groups whom received either traditional preoperative care or treatment following the Acerto (accelerating the total recovery of patients in the postoperative period) protocol. The study examined inflammatory response and insulin resistance by measuring levels of glucose, insulin, Homa-IR, reactive C protein, albumin, prealbumin, alpha 1 acid glycoprotein, interleukin 6, and glycosylated hemoglobin. In addition, the study investigated hydration levels, nausea and vomiting, hypertension, and length of hospital stay. Patients who followed the Acerto protocol showed no postoperative hypertensive crises (p = 0.03), and 30 % less vomiting (p = 0.35), and showed significant reductions in length of hospital stay, on average of 3 days versus 2 days (p = 0.02). There were not significant statistical differences between the two groups with respect to inflammatory response and insulin resistance (p > 0.05). This pilot study suggests that the prescription of the Acerto multimodal protocol for morbidly obese patients undergoing sleeve gastrectomy was safe, reduced the rate hypertensive complications, and the length of both ICU and hospital postoperative stay. However, there was no improvement in postoperative insulin resistance or inflammatory acute phase response.

    Gastrobronchial fistula (GBF) is a complication of esophageal, splenic, or antireflux surgeries and was recently described as a complication of bariatric surgery. Our aim was to study all cases of GBF after laparoscopic sleeve gastrectomy (LSG) managed in five French university bariatric centers in order to establish the incidence and to evaluate the different treatments of this complication. We retrospectively studied 13 patients which developed GBF after LSG performed between March 2007 and August 2012. Patients were separated into two groups: patients who had early gastric fistula which has evolved into a GBF (group 1) and patients who had a late gastric fistula, either directly GBF or a late gastric fistula evolved in GBF (group 2). Group 1 consisted of five patients and group 2 of eight patients. All patients were undernourished at diagnosis. Management of GBF was a combined thoraco-abdominal surgery with gastrojejunal anastomosis (n = 5) or total gastrectomy (n = 1), multiple endoscopic treatment and thoracic surgery (n = 3), an endobronchial valve (n = 1), total gastrectomy and thoracic drainage (n = 1), and transorificial intubation with thoracic surgery or drainage (n = 2). There was no mortality. All GBF healed. GBF after LSG is a serious complication which is not anecdotal. Most of the early gastric fistulas occuring after LSG become chronic and can evolve into a GBF. Surgical approach is an effective treatment. Endobronchial valve is a novel alternative.

    In the current study, we evaluated the efficacy of dual-phase three-dimensional (3D) CT angiography (CTA) in the assessment of the vascular anatomy, especially the right hepatic artery (RHA), before gastrectomy. The study initially included 714 consecutive patients being treated for gastric cancer. A dual-phase contrast-enhanced CT scan using 32-multi detector-row CT was performed for all patients. Among the 714 patients, 3D CTA clearly identified anomalies with the RHA arising from the superior mesenteric artery (SMA) in 49 cases (6.9 %). In Michels' classification type IX, the common hepatic artery (CHA) originates only from the SMA. Such cases exhibit defective anatomy for the CHA in conjunction with the celiac-splenic artery system, resulting in direct exposure of the portal vein beneath the #8a lymph node station, which was retrospectively confirmed by video in laparoscopic gastrectomy cases. Fused images of both 3D angiography and venography were obtained, and could have predicted the risk preoperatively, and the surgical finding confirmed its usefulness. Preoperative evaluations using 3D CTA can provide more accurate information about the vessel anatomy. The fused images from 3D CTA have the potential to reduce the intraoperative risks for injuries to critical vessel, such as the portal vein, during gastrectomy.

    To investigate the usefulness of a guide wire and triple lumen needle knife for removing stones in Billroth II (B-II) gastrectomy patients. Endoscopic sphincterotomy in patients with B-II gastrectomy is challenging. We used a new guide wire technique involving sphincterotomy by triple lumen needle knife through a forward-viewing endoscopy. This technique was performed in nine patients between August 2010 and June 2012. Sphincterotomy as described above was performed. Adequate sphincterotomy, successful stone removal, and complications were investigated prospectively. Sphincterotomy by triple lumen needle knife using guide wire was successful in all nine patients. Sphincterotomy started towards the 4-5 o'clock direction and continued to the upper margin of the papillary roof. Complete stone removal in one session was achieved in all patients. There were no procedure related complications, such as bleeding, pancreatitis, or perforation. In patients with B-II gastrectomy, guide wire using sphincterotomy by triple lumen needle knife through a forward-viewing endoscopy seems to be an effective and safe procedure for the removal of common bile duct stones.

    The curation of genetic variants from biomedical articles is required for various clinical and research purposes. Nowadays, establishment of variant databases that include overall information about variants is becoming quite popular. These databases have immense utility, serving as a user-friendly information storehouse of variants for information seekers. While manual curation is the gold standard method for curation of variants, it can turn out to be time-consuming on a large scale thus necessitating the need for automation. Curation of variants described in biomedical literature may not be straightforward mainly due to various nomenclature and expression issues. Though current trends in paper writing on variants is inclined to the standard nomenclature such that variants can easily be retrieved, we have a massive store of variants in the literature that are present as non-standard names and the online search engines that are predominantly used may not be capable of finding them. For effective curation of variants, knowledge about the overall process of curation, nature and types of difficulties in curation, and ways to tackle the difficulties during the task are crucial. Only by effective curation, can variants be correctly interpreted. This paper presents the process and difficulties of curation of genetic variants with possible solutions and suggestions from our work experience in the field including literature support. The paper also highlights aspects of interpretation of genetic variants and the importance of writing papers on variants following standard and retrievable methods. PMID:23317699

    To determine the appearance of appendicitis in the distal part of the organ (distal appendicitis) on computed tomographic (CT) scans and to evaluate the accuracy of diagnosis based on CT findings. CT scans and medical records in 180 consecutive patients with proved appendicitis were reviewed. Fourteen had distal appendicitis with at least a 3-cm length of normal proximal appendix. Appendiceal CT scans and initial reports were reviewed retrospectively. The proximal appendix was collapsed (n = 6) or was filled with contrast material (n = 6) or air (n = 2). Inflamed distal appendices averaged 13.2 mm in diameter and were associated with periappendiceal fat stranding (n = 14), adenopathy (n = 6), appendolith(s) (n = 4), or fluid (n = 2). Transition points consisted of a progressively narrowed appendiceal lumen and thickened wall (n = 5) or appendiceal diameter enlargement (n = 9). No cecal apical changes were seen. Scans in all 14 patients were prospectively interpreted as indicative of appendicitis, including 12 (86%) interpreted as indicative of distal appendicitis. CT findings are useful for the accurate diagnosis of distal appendicitis. Visualization of the proximal appendix alone is insufficient to exclude distal appendicitis.

    Proximal gastrectomy with esophagogastrostomy (PGEG) has been widely applied as a comparatively simple method. In this study, we used a questionnaire survey to evaluate the influence of various surgical factors on post-operative quality of life (QOL) after PGEG. In this post-gastrectomy syndrome assessment study, we analyzed QOL in 2,368 cases. Among these, 193 had undergone proximal gastrectomy and 115 had undergone PGEG. The Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 is a questionnaire consisting of 45 items, including the SF-8, the Gastrointestinal Symptom Rating Scale (GSRS), and other symptom items seemed to be specific to post-gastrectomy. The 23 symptom items were composed of seven symptom subscales (SS), including esophageal reflux, abdominal pain, and meal-related distress. These seven SS, total symptom score, ingested amount of food per meal, necessity for additional meals, quality of ingestion SS, ability to work, dissatisfaction with symptoms, dissatisfaction with the meal, dissatisfaction with working, dissatisfaction with daily life SS and change in body weight were evaluated as main outcome measures. In PGEG cases, we evaluated the influence on QOL of various surgical factors, such as procedures to prevent gastroesophageal regurgitation and size of the remnant stomach. The scores for esophageal reflux and dissatisfaction with the meal were higher in patients who had not undergone an anti-reflux procedure. In most cases, the preserved remnant stomach was more than two-thirds the size of the pre-operative stomach. When comparing patients with a remnant stomach two-thirds the pre-operative size and those with more than three-quarters, the diarrhea SS and necessity for additional meals scores were lower in the group with more than three-quarters. The indigestion, constipation, and abdominal pain subscales, and the total symptom score, were higher in patients who had not undergone pyloric bougie than in those who had. These results indicated

    Objective Patients undergoing total gastrectomy for cancer are at risk of malnourishment. The aim of this self-controlled study was to examine the effect of jejunostomy tube feeding (JTF) and other factors on postoperative weight and the incidence of jejunostomy-related complications in patients undergoing total gastrectomy for cancer. Methods All consecutive patients who underwent total gastrectomy for gastric cancer with jejunostomy placement were included from a prospective single-center database (2003–2014). Jejunostomy-related complications and postoperative weight changes were evaluated up to 12 months after surgery. Multivariable linear regression analysis was performed to identify factors associated with weight loss 12 months after gastrectomy. Results Of 113 patients operated in the study period, 65 received JTF after total gastrectomy for a median duration of 18 d [interquartile range (IQR), 10–55 d]. Jejunostomy-related complications occurred in 11 (17%) patients, including skin leakage (n=3) and peritoneal leakage (n=2), luxation (n=3), occlusion (n=2), infection (n=1) and torsion (n=1). In 2 (3%) patients, a reoperation was needed due to jejunostomy-related complications. The mean preoperative weight of patients was 71.8 kg (100%), and remained stable during JTF (73.9 kg, 103%, P=0.331). After JTF was stopped, the mean weight of patients decreased to 64.9 kg (90%) at 12 months after surgery (P<0.001). A high preoperative body mass index (BMI) (≥25 kg/m2) was associated with high postoperative weight loss compared to patients with a low BMI (<25 kg/m2) (16.3% vs. 8.6%, P=0.016). Conclusions JTF can prevent weight loss in the early postoperative phase. However, this is at the prize of possible complications. As weight loss in the long term is not prevented, routine JTF should be re-evaluated and balanced against the selected use in preoperatively malnourished patients. Special attention should be paid to patients with a high preoperative BMI, who

    The Astromaterials Acquisition and Curation Office at NASA Johnson Space Center (hereafter JSC curation) is responsible for curating all of NASA's extraterrestrial samples. JSC presently curates 9 different astromaterials collections in seven different clean-room suites: (1) Apollo Samples (ISO (International Standards Organization) class 6 + 7); (2) Antarctic Meteorites (ISO 6 + 7); (3) Cosmic Dust Particles (ISO 5); (4) Microparticle Impact Collection (ISO 7; formerly called Space-Exposed Hardware); (5) Genesis Solar Wind Atoms (ISO 4); (6) Stardust Comet Particles (ISO 5); (7) Stardust Interstellar Particles (ISO 5); (8) Hayabusa Asteroid Particles (ISO 5); (9) OSIRIS-REx Spacecraft Coupons and Witness Plates (ISO 7). Additional cleanrooms are currently being planned to house samples from two new collections, Hayabusa 2 (2021) and OSIRIS-REx (2023). In addition to the labs that house the samples, we maintain a wide variety of infra-structure facilities required to support the clean rooms: HEPA-filtered air-handling systems, ultrapure dry gaseous nitrogen systems, an ultrapure water system, and cleaning facilities to provide clean tools and equipment for the labs. We also have sample preparation facilities for making thin sections, microtome sections, and even focused ion-beam sections. We routinely monitor the cleanliness of our clean rooms and infrastructure systems, including measurements of inorganic or organic contamination, weekly airborne particle counts, compositional and isotopic monitoring of liquid N2 deliveries, and daily UPW system monitoring. In addition to the physical maintenance of the samples, we track within our databases the current and ever changing characteristics (weight, location, etc.) of more than 250,000 individually numbered samples across our various collections, as well as more than 100,000 images, and countless "analog" records that record the sample processing records of each individual sample.

    Elbow dislocation associated with ipsilateral distal radius fracture is a rare pattern of injury, although it is common for elbow dislocation and forearm fractures to occur separately. We report a rare case of a 20-year-old male who had a posterior elbow dislocation and ipsilateral distal radius fracture. Elbow dislocation was first reduced in extension and distal radius fracture was then reduced in flexion. Both the injuries were conservatively managed. At 6 months follow-up, the patient had no pain in his elbow and minimal pain in his wrist on heavy lifting and had resumed his work as a laborer. PMID:24082758

    In the recent years, nonextraction treatment approaches and noncompliance therapies have become more popular in the correction of space discrepancies. One of the conventional approaches for space gaining in the arches without patient compliance is done by using certain extra oral appliances or intraoral appliance. The greatest advantage of certain appliances like fixed functional and molar distalization appliances is that they minimize the dependence on patient cooperation. Molar distalization appliances like pendulum appliance which distalizes the molar rapidly without the need of head gear can be used in patients as a unilateral space gaining procedure due to buccal segment crowding.

    Distal radioulnar joint (DRUJ) problems can occur as a result of joint instability, abutment, or incongruity. The DRUJ is a weight-bearing joint; the ulnar head is frequently excised either totally or partially, and in some cases it is fused, because of degenerative, rheumatoid, or posttraumatic arthritis. Articles about these procedures report the ability to pronate and supinate, but they rarely discuss grip strength, and even less do they address lifting capacity. We report the long term results of the first 35 patients who underwent total DRUJ arthroplasty with the Aptis DRUJ prosthesis after 5 years follow-up. Surgical indications were all causes of dysfunctional DRUJ (degenerative, posttraumatic, autoimmune, congenital). We recorded data for patient demographics, range of motion (ROM), strength, and lifting capacity of the operated and of the nonoperated extremity. Pain and functional assessments were also recorded. The Aptis DRUJ prosthesis, a bipolar self-stabilizing DRUJ endoprosthesis that restores forearm function, consists of a semiconstained and modular implant designed to replace the function of the ulnar head, the sigmoid notch of the radius, and the triangular fibrocartilage ligaments. The surgical technique is presented in detail. The majority of the patients regained adequate ROM and improved their strength and lifting capacity to the operated side. Pain and activities of daily living were improved. Twelve patients experienced complications, most commonly being extensor carpi ulnaris (ECU) tendinitis, ectopic bone formation, bone resorption with stem loosening, low-grade infection, and need for ball replacement. The Aptis total DRUJ replacement prosthesis is an alternative to salvage procedures that enables a full range of motion as well as the ability to grip and lift weights encountered in daily living activities.

    The measurement of a single abdominal image on computed tomography (CT) can provide an estimate of the total body skeletal muscle. We evaluate the change of the area of the psoas major muscle (PMMA) in a CT which was performed routinely after gastrectomy in gastric cancer. A total of 119 gastric cancer patients who underwent gastrectomy were enrolled for the study. A CT image at the top of the iliac crest level was obtained at the following times: 3 postoperative months (POM), 6 POM, 1 postoperative year (POY), 2 POY, 3 POY, and 5 POY. We analyzed the change rate of PMMA after gastrectomy and before or after recurrence. PMMA change after gastrectomy was approximately between -8 and -10% over the 5-year observation period. PMMA in the R2 (macroscopic residual tumor)/recurrence group was lower than that in the no recurrence group, and a significant difference was observed at 2 POY (-21.7 ± 3.6% vs. -7.9 ± 2.3%, p < 0.01). PMMA after freshly diagnosed recurrence had decreased significantly by 14.1 ± 1.8% (p < 0.01). Evaluation of PMMA change by CT after gastrectomy could assist in the diagnosis of the progression of cancer state in gastric cancer patients. © 2017 S. Karger AG, Basel.

    Can we use programs for automated or semi-automated information extraction from scientific texts as practical alternatives to professional curation? I show that error rates of current information extraction programs are too high to replace professional curation today. Furthermore, current IEP programs extract single narrow slivers of information, such as individual protein interactions; they cannot extract the large breadth of information extracted by professional curators for databases such as EcoCyc. They also cannot arbitrate among conflicting statements in the literature as curators can. Therefore, funding agencies should not hobble the curation efforts of existing databases on the assumption that a problem that has stymied Artificial Intelligence researchers for more than 60 years will be solved tomorrow. Semi-automated extraction techniques appear to have significantly more potential based on a review of recent tools that enhance curator productivity. But a full cost-benefit analysis for these tools is lacking. Without such analysis it is possible to expend significant effort developing information-extraction tools that automate small parts of the overall curation workflow without achieving a significant decrease in curation costs.

    The six Apollo surface missions returned 2,196 individual rock and soil samples, with a total mass of 381.6 kg. Samples were collected based on visual examination by the astronauts and consultation with geologists in the science back room in Houston. The samples were photographed during collection, packaged in uniquely-identified containers, and transported to the Lunar Module. All samples collected on the Moon were returned to Earth. NASA's upcoming return to the Moon will be different. Astronauts will have extended stays at an out-post and will collect more samples than they will return. They will need curation and analysis facilities on the Moon in order to carefully select samples for return to Earth.

    Distal radius fractures are one of the most common upper extremity fractures. Athletes with distal radius fractures are treated according to the same principles as non-athletes but present several unique considerations. At all levels of sport, injured athletes desire to return to play as rapidly as possible. Earlier operative fixation may allow an athlete to return to play more quickly. Volar locking plates are most commonly used for operative treatment of distal radius fractures due to their stability and low incidence of complications. Although the majority of distal radius fractures in athletes are treated non-operatively, operative intervention is offered when required to restore and maintain acceptable skeletal alignment. Return to sport is individualized guided by fracture stability, athlete age, and wrist-specific demands for competition.

    Physical samples are important observational units in Earth and Space sciences. Samples and their derived data play vital role in scientific validation and reproducibility. Systematic practices and technical solutions are required to curate and publish samples and their data on the Web. Persistent identifiers ensure unambiguous identification, and enable linkage and citation of samples and associated data sets. The International Geo Sample Number (IGSN) is a persistent and globally unique identifier for physical samples and sample collections. IGSNs are allocated to clients (e.g., laboratories, projects, individual users) through agents. Agents are institutions that represent the IGSN e.V., the IGSN Implementation Organization. For example, CSIRO, Geoscience Australia and Curtin University are IGSN allocating agents in Australia. Clients register IGSNs for samples through the respective agent's registration services. The Discovery research program of CSIRO is conducting research in the prolific metallogenic provinces of the Capricorn Orogen - a regional study aimed to define distal footprints of covered ore systems. In CSIRO, the Capricorn Distal Footprints (CAPDF) project is one of the early adopters of the IGSN in its sample curation. The project involves collection of various samples, including water, rock, sediment, vegetation and regolith, which are collected by different researchers. The application of IGSN requires not only the supporting infrastructure and tools (e.g., user interface, service, metadata model) but also systematic workflows to cater different users, i.e., practices of laboratories or individual researchers. We present the application of the IGSN in the context of the CAPDF project as a sample inventory management system, samples identification in publications and sample discovery through a web portal. We describe workflows that demonstrate IGSN integration into existing sample curation practices and highlight challenges and benefits of such a

    It is widely accepted that curation of variation in genes is best performed by experts in those genes and their variation. However, obtaining funding for such variation is difficult even though up‐to‐date lists of variations in genes are essential for optimum delivery of genetic healthcare and for medical research. This study was undertaken to gather information on gene‐specific databases (locus‐specific databases) in an effort to understand their functioning, funding and needs. A questionnaire was sent to 125 curators and we received 47 responses. Individuals performed curation of up to 69 genes. The time curators spent curating was extremely variable. This ranged from 0 h per week up to 5 curators spending over 4 h per week. The funding required ranged from US$600 to US$45000 per year. Most databases were stimulated by the Human Genome Organization‐Mutation Database Initiative and used their guidelines. Many databases reported unpublished mutations, with all but one respondent reporting errors in the literature. Of the 13 who reported hit rates, 9 reported over 52 000 hits per year. On the basis of this, five recommendations were made to improve the curation of variation information, particularly that of mutations causing single‐gene disorder: 1. A curator for each gene, who is an expert in it, should be identified or nominated. 2. Curation at a minimum of 2 h per week at US$2000 per gene per year should be encouraged. 3. Guidelines and custom software use should be encouraged to facilitate easy setup and curation. 4. Hits per week on the website should be recorded to allow the importance of the site to be illustrated for grant‐giving purposes. 5. Published protocols should be followed in the establishment of locus‐specific databases. PMID:17400791

    Ventriculoperitoneal shunt revision is a common procedure. Disconnection and fracture of the distal catheter remain a common cause of ventriculoperitoneal shunt malfunction. To describe a novel procedure for peritoneal replacement of the distal catheter by using a guidewire and a modified Seldinger technique (guidewire-assisted distal catheter replacement) and retrospectively evaluate the results of the surgical procedure. Between September 2005 and December 2013, 68 patients were treated by a single surgeon (DMW) with distal catheter replacement using our technique. In brief, the previously placed distal catheter was exposed at its entry site into the abdomen. A soft guidewire with hydrophilic coating was inserted down the distal catheter into the peritoneum. The distal catheter was then removed over the guidewire, leaving the guidewire in place. A peel-away sheath and dilator were then inserted over the guidewire, and the dilator and guidewire were removed. The new distal catheter was then passed from the valve to the abdomen and was then fed through the peel-away sheath into the peritoneum. Charts were retrospectively reviewed for preoperative presentation, operative technique, and postoperative outcome. Records were specifically examined for any early or late complications. The mean patient age at surgery was 13 years. No immediate acute complications were noted. Of the 68 total patients, 45 patients had more than 6 months of follow-up. Of the 68 patients, 7 patients required another distal revision after guidewire-assisted distal catheter replacement. Distal shunt malfunction due to a mechanical failure is a common reason for shunt revision. We describe a technique for guidewire-assisted distal catheter replacement.

    Abstract- The Planetary Material Sample Curation Facility of JAXA (PMSCF/JAXA) was established in Sagamihara, Kanagawa, Japan, to curate planetary material samples returned from space in conditions of minimum terrestrial contaminants. The performances for the curation of Hayabusa-returned samples had been checked with a series of comprehensive tests and rehearsals. After the Hayabusa spacecraft had accomplished a round-trip flight to asteroid 25143 Itokawa and returned its reentry capsule to the Earth in June 2010, the reentry capsule was brought back to the PMSCF/JAXA and was put to a series of processes to extract recovered samples from Itokawa. The particles recovered from the sample catcher were analyzed by electron microscope, given their ID, grouped into four categories, and preserved in dimples on quartz slide glasses. Some fraction of them has been distributed for initial analyses at NASA, and will be distributed for international announcement of opportunity (AO), but a certain fraction of them will be preserved in vacuum for future analyses.

    Purpose: To analyze the outcome of adjuvant chemoradiotherapy for patients with distal common bile duct (CBD) cancer who underwent curative surgery, and to identify the prognostic factors for these patients. Methods and Materials: Between January 1991 and December 2002, 38 patients with adenocarcinoma of the distal CBD underwent curative resection followed by adjuvant chemoradiotherapy. There were 27 men and 11 women, and the median age was 60 years (range, 34-73). Adjuvant radiotherapy was delivered to the tumor bed and regional lymph nodes up to 40 Gy at 2 Gy/fraction with a 2-week planned rest. Intravenous 5-fluorouracil (500mg/m{sup 2}/day) was given on day 1 to day 3 of each split course. The median follow-up period was 39 months. Results: The 5-year overall survival rate of all patients was 49.1%. On univariate analysis, only histologic differentiation (p = 0.0005) was associated with overall survival. Tumor size ({<=}2cm vs. >2cm) had a marginally significant impact on the treatment outcome (p = 0.0624). However, there was no difference in overall survival rates between T3 and T4 tumors (p = 0.6189), for which the main determinants were pancreatic and duodenal invasion, respectively. On multivariate analysis, histologic differentiation (p = 0.0092) and tumor size (p = 0.0046) were independent risk factors for overall survival. Conclusions: Long-term survival can be expected in patients with distal CBD cancer undergoing curative surgery and adjuvant chemoradiotherapy. Histologic differentiation and tumor size were significant prognostic factors predicting overall survival, whereas duodenal invasion was not. This finding suggests the need for further refinement in tumor staging.

    Sleeve gastrectomy constitutes an effective surgical procedure for the treatment of morbid obesity. The aim of the present study was to establish the effects of sleeve gastrectomy and caloric restriction on weight loss and cardiovascular parameters in diet-induced obese (DIO) rats. Male Wistar DIO rats were subjected to surgical interventions (n = 30) (sham operation, sleeve gastrectomy, or pair-fed to the amount of food eaten by sleeve-gastrectomized animals and compared to lean control rats) or dietary interventions (n = 40) (fed ad libitum a normal diet (ND) or a high-fat diet or an ND with a caloric restriction of 25 %). Systolic blood pressure (SBP), diastolic blood pressure, and mean blood pressure values and heart rate (HR) were recorded in conscious, resting animals by noninvasive tail-cuff plethysmography before and 3 weeks after surgical or dietary interventions. Both sleeve gastrectomy and caloric restriction induced a reduction in body weight, whole-body adiposity, and serum leptin together with an increased excess weight loss in DIO rats. Sleeve gastrectomy was further associated with an improvement in insulin resistance and the lipid profile, as well as with a reduction in serum ghrelin levels. A decrease in HR and heart weight was observed in caloric-restricted groups. Sleeve-gastrectomized rats not only exhibited a reduction in HR (∆HR = -45 ± 19 bpm) but also in SBP values (∆SBP = -22 ± 10 mmHg) compared to the DIO rats (∆SBP = 14 ± 8 mmHg). Our findings provide evidence that the beneficial effects of sleeve gastrectomy on blood pressure values are beyond weight loss in rats with diet-induced obesity.

    Sleeve gastrectomy (SG) is gaining popularity and has become the procedure of choice for many bariatric surgeons. Long-term weight loss failure is not uncommon. The preferred revisional procedure for these patients is still under debate. The objective of this study was to assess the safety and efficacy of laparoscopic gastric bypass as a revisional surgery for sleeve gastrectomy patients with weight loss failure. The study was done at a bariatric surgery center in a university hospital. We reviewed our prospectively collected database and identified all patients who underwent conversion of a sleeve gastrectomy to a gastric bypass for weight loss failure. Data on patient demographics, baseline characteristics, and outcomes of bariatric surgery were retrieved. Twenty-three patients with a mean body mass index (BMI) of 41.6 kg/m2 (range 34.1-50.1 kg/m2) underwent conversion to a gastric bypass. Four patients underwent a gastric band prior to the sleeve gastrectomy, and two patients underwent a re-sleeve gastrectomy prior to conversion to a gastric bypass. At a mean follow-up of 24 months (range 9-46 months), the average body mass index (BMI) decreased to 33.8 kg/m2 and the excess body mass index loss (EBMIL) was 42.6%. Diabetes, hypertension, dyslipidemia, and obstructive sleep apnea resolved or improved in 44.4, 45.5, 50, and 50% of the patients, respectively. Three patients developed early postop complications (13%), while late complications occurred in four patients (17%). Converting a sleeve gastrectomy to a gastric bypass for weight loss failure is safe, yet weight loss benefit is limited.

    Surgery is the most effective method for the treatment of morbid obesity. Beneficial effects of bariatric surgery are due to both changed anatomy and consequential alterations in hormonal and metabolic status. Based on the experience with former standard bariatric procedures, the idea came out of a new combined bariatric procedure that could provide better control of glucose level and weight loss. The procedure is a hybrid of sleeve gastrectomy and mini-gastric bypass, therefore uniting advantages of both procedures: one anastomosis, achieved effects of restriction and malabsorption and affection of both dominant endocrine systems that result in an increase in incretin level and a decrease in ghrelin level. However, the procedure is yet a novel one and these hypotheses are about to be examined in the already announced research project.

    Background. Some meta-analyses of case-controlled studies (CCSs) have shown that laparoscopic or laparoscopy-assisted total gastrectomy (LTG) had some short-term advantages over open total gastrectomy (OTG). However, postoperative complications differed somewhat among the meta-analyses, and some CCSs included in the meta-analyses had mismatched factors between LTG and OTG. Methods. CCSs comparing postoperative complications between LTG and OTG were identified in PubMed and Embase. Studies matched for patients' status, tumor stage, and the extents of lymph-node dissection were included. Outcomes of interest, such as anastomotic, other intra-abdominal, wound, and pulmonary complications, were evaluated in a meta-analysis performed using Review Manager version 5.3 software. Result. This meta-analysis included a total of 2,560 patients (LTG, 1,073 patients; OTG, 1,487 patients) from 15 CCSs. Wound complications were significantly less frequent in LTG than in OTG (n = 2,430; odds ratio [OR] 0.30, 95% confidence interval [CI] 0.29–0.85, P = 0.01, I2 = 0%, and OR 0.46, 95% CI 0.17–0.52, P < 0.0001, I2 = 0%). However, the incidence of anastomotic complications was slightly but not significantly higher in LTG than in OTG (n = 2,560; OR 1.44, 95% CI 0.96–2.16, P = 0.08, I2 = 0%). Conclusion. LTG was associated with a lower incidence of wound-related postoperative complications than was OTG in this meta-analysis of CCSs; however, some concern remains about anastomotic problems associated with LTG.

    Background Although pulmonary endarterectomy (PEA) is potentially curative in chronic thromboembolic pulmonary hypertension (CTEPH), some patients have distally distributed disease that is not amenable to surgery. The aetiology and characteristics of this patient group are currently not well understood. Objectives This study compares the baseline demographic features and outcomes in subjects with distal CTEPH, those with proximal CTEPH and those with idiopathic pulmonary arterial hypertension (IPAH) to determine whether these conditions represent separate entities or whether they exist along the same spectrum of disease. Methods The medical history, clinical characteristics, bone morphogenetic protein receptor type II (BMPR2) mutation status and outcomes of 96 subjects with IPAH, 35 with distal CTEPH and 68 with proximal CTEPH referred to a single specialist centre between 1994 and 2005 were reviewed. Results There were significant differences between the distal CTEPH, proximal CTEPH and IPAH groups in age (55.9 years vs 54.8 years vs 46.2 years, p<0.001), proportion who were male (43% vs 69% vs 29%, p<0.001), previous deep vein thrombosis (28.6% vs 30.9% vs 3.1%, p<0.001), positive BMPR2 status (0% vs 0% vs 15%, p = 0.018), mean pulmonary artery pressure (47.3 mm Hg vs 45.4 mm Hg vs 54.8 mm Hg, p<0.001) and total pulmonary resistance (12.9 WU vs 12.4 WU vs 18.1 WU, p<0.001). Patients with distal CTEPH and those with IPAH were managed similarly and had comparable survival characteristics (1 year survival 77% vs 86%; 3 year survival 53% vs 60%; p = 0.68). Conclusions Patients with distal CTEPH share certain demographic features with patients with proximal CTEPH that not only indicate a common aetiology but also help to differentiate them from patients with IPAH. Despite more favourable haemodynamic parameters in those with distal CTEPH, patients in this group had a poor long‐term outcome which was similar to that of patients

    Sleeve gastrectomy is a rapid and less traumatic operation, which thus far is showing good resolution of comorbidities and good weight loss if a narrower channel is constructed than for the duodenal switch. There are potential intraoperative complications, which must be recognized and treated promptly. Like other bariatric operations, there are variations in the technique used. The laparoscopic sleeve gastrectomy (LSG) is being performed for super-obese and high-risk patients, but its indications have been increasing. A second-stage bariatric operation may be performed if necessary, with increased safety. Long-term results of LSG and further networking are anxiously awaited.

    The aim of the present study was to inquire into the feasibility, surgical skills required and short-term effect of a laparoscopic resection of the bursa omentalis and lymph node scavenging with radical gastrectomy. In this study, the clinical data of 18 patients who received a laparoscopic resection of the bursa omentalis with radical gastrectomy in the Department of Gastrointestinal Surgery, Guangdong Province Hospital of Traditional Chinese Medicine (Guangzhou, Guangdong, China) during the period between January 2012 and January 2014. A retrospective analysis was performed and the surgical duration, bursa omentalis resection time, amount of bleeding during the surgery, post-operative complications associated with the surgery, length of hospital stay, number of lymph nodes scavenged and short-term follow-up results were assessed. The results indicated that all of these 18 patients successfully received a resection of the bursa omentalis and no one required conversion to open surgery. The mean surgical duration was 289.3±30.3 min, the bursa omentalis resection time was 46.1±18.6 min and the amount of bleeding was recorded as 35.5±6.5 ml in these patients. No patients suffered from post-operative complications, such as pancreatic fistulae, anastomotic fistulae, intestinal obstructions or succumbing to the surgery, and no patients succumbed within a 6-month follow-up period. In conclusion, for advanced gastric carcinoma, laparoscopic resection of the bursa omentalis and lymph node scavenging with radical gastrectomy is feasible. In addition to meeting the requirement that the operator should be skilled and experienced in open bursa omentalis resection, and have well-knit basic skills in using a laparoscope, attention must also be paid to the construction of the surgical team.

    Hereditary diffuse gastric cancer (HDGC) is an autosomal dominant cancer syndrome. Up to 30% of families with HDGC have mutations in the E-cadherin gene, CDH1. The role of prophylactic versus therapeutic gastrectomy for HDGC was studied prospectively. Eighteen consecutive patients with CDH1 mutations and positive family history were studied prospectively, including 13 without and 5 with symptoms. Proportions were compared by Fisher's exact test, and survival by the Breslow modification of the Wilcoxon rank-sum test. Each patient underwent total gastrectomy (TG), and 17 (94%) were found to have signet ring cell adenocarcinoma. Twelve of 13 asymptomatic patients had T1, N0 cancer, and only 2/12 (16%) had it diagnosed preoperatively despite state-of-the-art screening methods. Each asymptomatic patient did well postoperatively, and no patient has recurred. For five symptomatic patients, each (100%) was found to have signet ring cell adenocarcinoma (P = 0.002 versus asymptomatic) by preoperative endoscopy; three (60%) had lymph node involvement and two (40%) had distant metastases at time of operation. Two-year survival was 100% for asymptomatic and 40% for symptomatic patients (P < 0.01). The data show that asymptomatic patients with family history of HDGC and CDH1 mutation have high probability of having signet ring cell adenocarcinoma of the stomach that is not able to be diagnosed on endoscopy; when symptoms arise, the diagnosis can be made by endoscopy, but they have metastases and decreased survival. Surveillance endoscopy is of limited value, and prophylactic gastrectomy (PG) is recommended for patients with family history of HDGC and CDH1 mutations.

    AIM: To elucidate the effect of a proton pump inhibitor (PPI, rabeparazole) on oesophageal bile reflux in oesophagitis after total gastrectomy. METHODS: Twenty-one 8-week-old male Wistar rats were studied. They were performed oesophagoduodenostomy of total gastrectomy to induce oesophageal reflux of biliary and pancreatic juice. Five rats were performed the sham operation (Sham). On post-operative day 7, they were treated with saline (Control) (n = 8) or PPI (rabeprazole, 30 mg/kg per day, ip ) (n = 8) for 2 wk. On post-operative 21, all rats were sacrificed and each oesophagus was evaluated histologically. Oesophageal injury was evaluated by macroscopic and microscopic findings as well as the expression of cyclooxygenase-2 (COX2). We measured bile acid in the oesophageal lumen and the common bile duct. RESULTS: At 3 wk after surgery, a histological study analysis revealed an increase in the thickness of the epithelium, elongation of the lamina propria and basal cell hyperplasia in the oesophageal mucosa. The macroscopic ulcer score and microscopic ulcer length of the control group were significantly higher compared to those of the rabeprazole- treated group. The expression of COX2 was significantly increased according to the immunostaining in the control group compared to rabeprazole- treated group. Although there was no difference between the control and PPI groups in the total bile acid in the common bile duct, the bile acid activity in the oesophageal lumen was significantly decreased in the rabeprazole- treated group due to augmentation of the duodenal motor complex. CONCLUSION: With this model, rabeprazole is good effect for reflux esophagitis after total gastrectomy from bile reflux. Bile acid is an important factor in the mucosal lesion induced by duodenal reflux. PMID:25685608

    To investigate the influence of obesity on short-term outcomes after laparoscopy-assisted radical gastrectomy. Clinical data of 214 patients with gastric cancer, who underwent laparoscopy-assisted radical gastrectomy between May 2009 and December 2012 were analyzed retrospectively. Patients were divided into two groups, consisting of obese and non-obese patients. In the obese group, the BMI was ≥ 25.0 kg/m² (n=66), and in the non-obese group was <25.0 kg/m² (n=148). Operative procedure and postoperative recovery were compared between the two groups. The operative time was longer in obese group than that in non-obese group [(271.5 ± 51.2) min vs. (252.1 ± 53.6) min, P<0.05]. The number of retrieved lymph nodes in obese group was less than that in non-obese group (26.2 ± 10.3 vs. 30.3 ± 12.4, P<0.05). No significant differences were observed in terms of blood loss, blood transfusion rate, conversion to laparotomy and time to first flatus between these two groups (all P>0.05). There were no significant differences between the two groups with respect to postoperative complications rate (25.8% vs. 20.9%, P>0.05) and perioperative mortality (1.5% vs. 0.7%, P>0.05). However, minor surgery-related complication rate was higher in obese group(16.7% vs. 6.8%, P<0.05), mainly presented as delayed gastric emptying. There was no difference in perioperative mortality between the two groups (1.5% vs. 0.7%, P>0.05). Although obesity prolongs the duration of laparoscopy-assisted radical gastrectomy, and increases the risk of minor surgery-related complications, it has no influence on the surgical safety.

    The use of a Fobi ring to prevent pouch dilation is sometimes used in Roux-en-Y gastric bypass (RYGB). Recently, it has been extrapolated to laparoscopic sleeve gastrectomy (LSG) procedures by placing a fixed-ring band a few centimeters below the gastroesophageal junction (GEJ). What is the consequence if a patient develops a leak? Tertiary metropolitan referral center, Australia. Over 18 months, all patients with either a conventional LSG or a fixed-ring banded sleeve gastrectomy (BLSG) who presented with a proven leak complication were included. The management approaches along with the surgical, endoscopic, and percutaneous procedures used were examined. Six patients had a BLSG leak and 6 had a LSG leak. All patients had leak resolution. There was no significant difference in body mass index (BMI), time to leak, initial white cell count (WCC), and C-reactive protein (CRP) levels between the 2 groups. LSG patients required a median of 2 endoscopic procedures (range: 1-3). Stents were deployed in 3 patients. All BLSG patients required a single surgical intervention with laparoscopic washout, drainage, removal of band±feeding jejunostomy. One stent was deployed in 1 BLSG patient. BLSG leak resolution was found at 34±12 days versus 85±12 days in the LSG group (P< .05). The BLSG is a new modification of the sleeve gastrectomy procedure. This study presents a management strategy for leak resolution employed in BLSG patients. The presence of a foreign body as a persistent nidus of infection mandates band removal.

    To study the impact of obesity on the short-term outcomes after laparoscopic-assisted radical gastrectomy. A total of 531 gastric cancer patients underwent radical resection at the Fujian Medical University Union Hospital between May 2007 and June 2010. There were 83 patients with BMI ≥ 25 kg/m(2) (obese group) and 448 patients with BMI<25 kg/m(2) (non-obese group). Intraoperative and postoperative parameters, and short-term survival rates between the two groups were compared. There was no significant difference between obese and non-obese patients in terms of conversion rate (2.4% vs. 1.8%, P>0.05). The operative time in obese group was (224.7 ± 57.3) min, which was significantly longer than that in non-obese group [(210.0 ± 57.9) min, P<0.05]. However, no statistically significant differences were observed between obese and non-obese groups in terms of blood loss, blood transfusion rate, elevated leukocyte and granulocyte count on the first postoperative day, time to temperature recovery, first flatus, and postoperative hospital stays(P>0.05). The mean number of retrieved lymph nodes in obese group was (24.8 ± 8.4), and was significantly less than that of non-obese group[(29.9 ± 10.2), P<0.05]. There were no significant differences between obese and non-obese groups in postoperative complication rate (16.8% vs. 10.2%, P>0.05), postoperative mortality(1.2% vs. 0.4%, P>0.05), and 3-year overall survival (68.8% vs. 74.0%, P>0.05). Obesity is associated with prolonged operative time for laparoscopic radical gastrectomy. However, the short-term outcomes after the laparoscopic radical gastrectomy is not influenced by obesity.

    Malignancy is a secondary cause of sarcopenia, which is associated with impaired cancer treatment outcomes. The aim of this study was to investigate the prevalence of preoperative sarcopenia among elderly gastric cancer patients undergoing gastrectomy and the differences in preoperative dietary intake and postoperative complications between sarcopenic and non-sarcopenic patients. Ninety-nine patients over 65 years of age who underwent gastrectomy for gastric cancer were analyzed. All patients underwent gait and handgrip strength testing, and whole-body skeletal muscle mass was measured using a bioimpedance analysis technique based on the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm for the evaluation of sarcopenia before surgery. Preoperative dietary intake was assessed using a food frequency questionnaire. Of these patients, 21 (21.2 %) were diagnosed with sarcopenia. Sarcopenic patients consumed fewer calories and less protein preoperatively (23.9 vs. 27.8 kcal/kg ideal weight/day and 0.86 vs. 1.04 g/kg ideal weight/day; P = 0.001 and 0.0005, respectively). Although the overall incidence of postoperative complications was similar in the two groups (57.1 % vs. 35.9 %; P = 0.08), the incidence of severe (Clavien-Dindo grade ≥ IIIa) complications was significantly higher in the sarcopenic group than in the non-sarcopenic group (28.6 % vs. 9.0 %; P = 0.029). In the multivariate analysis, sarcopenia alone was identified as a risk factor for severe postoperative complications (odds ratio, 4.76; 95 % confidence interval, 1.03-24.30; P = 0.046). Preoperative sarcopenia as defined by the EWGSOP algorithm is a risk factor for severe postoperative complications in elderly gastric cancer patients undergoing gastrectomy.

    Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables.One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications.Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP.There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results.

    The effect of laparoscopic sleeve gastrectomy (SG) on gastroesophageal reflux disease (GERD) has been a controversial issue. There have been limited studies on this aspect and most of the published studies are retrospective. Therefore, a prospective study was designed to objectively assess the problem. The objective of this study was to assess the impact of SG on symptoms of gastroesophageal reflux using questionnaire, endoscopy, and radionuclide scintigraphy. Thirty-two patients undergoing laparoscopic sleeve gastrectomy were assessed for gastroesophageal reflux using Carlsson Dent Questionnaire and GERD questionnaire before and after surgery at three monthly intervals. They were also subjected to upper GI endoscopy (UGIE) and radionuclide scintigraphy both pre- and postoperatively. Mean preoperative weight and body mass index were 126.5 kg and 47.8 kg/m2, respectively. Mean percent excess weight loss at 12 months was 64.3 ± 18.4. Both the Carlsson Dent Score (CDS) and Severity Score (SS) exhibited a decline from 2.88 to 1.63 (p<0.05) and 2.28 to 1.06 (p<0.05), respectively after 12 months. Radionuclide scintigraphy revealed a significant rise of GERD from 6.25% to 78.1% in the postoperative period (p<0.001). UGIE showed a rise in incidence of esophagitis from 18.8% to 25%; however, there was improvement in all patients except one in terms of reduction of severity of esophagitis. Presence of GERD may not be considered as a contra-indication for sleeve gastrectomy. There is improvement of GERD as assessed by symptom questionnaires, as well as improvement in grade of esophagitis. The new onset GERD detected on scintigraphy may not be pathologic as there is a decrease in total acid production postsurgery; however, it still remains an important issue and needs long-term follow-up.

    The aim of this study was to investigate the efficacy of postoperative scheduled intravenous acetaminophen to reduce the opioid use and enhance recovery after gastrectomy.Opioid use is reportedly associated with delayed recovery of gastrointestinal (GI) peristalsis and postoperative nausea/vomiting (PONV) despite of acceptable efficacy for pain control.Of 147 and 96 consecutive patients who underwent gastrectomy for gastric cancer before and after introduction of postoperative scheduled intravenous acetaminophen, propensity score matched population was created and short-term clinical outcomes were compared.Significant defervescence was demonstrated in Acetaminophen group (A-group) compared with control group (C-group) during the perioperative period (P < 0.001), whereas no significant difference was observed in postoperative inflammatory parameters. The incidence of postoperative complications was similar between the groups. The number of patient-controlled analgesia (PCA) pushes was significantly reduced in the A-group (P = 0.007) and the frequency of use of other nonopioid analgesics was also significantly reduced in the A-group (P < 0.001). Both daily and cumulative opioid use was significantly reduced in the A-group (P < 0.001). The time to first flatus and defecation was decreased in the A-group (P < 0.001 and P = 0.038, respectively). The incidence of PONV was significantly reduced from 26.0% to 12.5% after introduction of intravenous acetaminophen (P = 0.017), and hospital stay tended to be decreased in the A-group (13.2 vs 14.7 days, P = 0.069)Postoperative scheduled intravenous acetaminophen decreased opioid use and may be associated with enhanced recovery after gastrectomy.

    To determine if the morbidity and postoperative mortality after a full gastrectomy for gastric cancer performed on patients of more than 70 years of age were different from those of younger patients. Between 1980 and 1999, a total of 411 gastrectomies for gastric adenocarcinoma were performed at the Institute of Cancer Diseases (INEN). Of these, 87 were inpatients older than 70 years of age (elderly group) and 92 were inpatients between 50 and 59 years of age (young group). The clinical record of both groups were studied and the clinical-pathological features, morbidity and postoperative mortality, staying time in hospital and survival rate were compared. There was no significant difference between the two groups regarding clinical-pathological features except in the TNM stage. In the elderly group 23.0% had stage IV and 43.5% in the young group (p=0.007). The average operating time in the elderly group was shorter than in the young group (5.5 hours versus 6.0 hours, p=0.015). The morbidity for the elderly group was 29.9% and that of the young group was 34.8%, whereas the postoperative mortality for the elderly and young groups was 4.6% and 2.2%, respectively. Pneumonia was the most frequent postoperative complication (14.8%) and the primary cause of postoperative death in the elderly group. Time in hospital and survival were similar between both groups. The morbidity and postoperative mortality after a full gastrectomy for cancer of the stomach in the elderly is no different from those found in younger patients.

    Background and study aims Staple-line leaks occur in 1 % - 7 % of patients who undergo sleeve gastrectomy, and can be challenging to treat. The success of endoscopic approaches decreases as leaks develop into chronic sinus tracts. Endoscopic septotomy has been used to facilitate healing of refractory leaks by incision and enlargement of the tract to allow direct communication with the gastric lumen and internal drainage. Patients and methods We reviewed the technique and outcomes among patients who underwent endoscopic septotomy at two centers for the management of sleeve gastrectomy-associated gastric fistulas and perigastric collections refractory to occlusive endoscopic therapies. Results Nine patients underwent endoscopic septotomy at a mean of 8.6 weeks after leak diagnosis, following failure of percutaneous and conventional endoscopic modalities. Perigastric collections ranged from 3 cm to 10 cm in size. The mean procedure time for endoscopic septotomy was 87.2 minutes. Multiple endoscopic septotomy procedures (mean 2.3, range 1 - 4) were required to achieve radiological resolution. The mean follow-up period was 21.2 weeks, and all nine patients achieved symptom resolution without the need for surgery. Bleeding at the time of endoscopic septotomy occurred in three patients, and was managed with endoscopic clips and did not require transfusion. No other adverse events or delayed complications were recorded. Conclusions Endoscopic septotomy appears to be a safe and effective technique for the management of sleeve gastrectomy-associated fistulae and collections, including those refractory to other endoscopic and percutaneous methods.

  18. Management of distal humeral coronal shear fractures

    Coronal shear fractures of the distal humerus are rare, complex fractures that can be technically challenging to manage. They usually result from a low-energy fall and direct compression of the distal humerus by the radial head in a hyper-extended or semi-flexed elbow or from spontaneous reduction of a posterolateral subluxation or dislocation. Due to the small number of soft tissue attachments at this site, almost all of these fractures are displaced. The incidence of distal humeral coronal shear fractures is higher among women because of the higher rate of osteoporosis in women and the difference in carrying angle between men and women. Distal humeral coronal shear fractures may occur in isolation, may be part of a complex elbow injury, or may be associated with injuries proximal or distal to the elbow. An associated lateral collateral ligament injury is seen in up to 40% and an associated radial head fracture is seen in up to 30% of these fractures. Given the complex nature of distal humeral coronal shear fractures, there is preference for operative management. Operative fixation leads to stable anatomic reduction, restores articular congruity, and allows initiation of early range-of-motion movements in the majority of cases. Several surgical exposure and fixation techniques are available to reconstruct the articular surface following distal humeral coronal shear fractures. The lateral extensile approach and fixation with countersunk headless compression screws placed in an anterior-to-posterior fashion are commonly used. We have found a two-incision approach (direct anterior and lateral) that results in less soft tissue dissection and better outcomes than the lateral extensile approach in our experience. Stiffness, pain, articular incongruity, arthritis, and ulnohumeral instability may result if reduction is non-anatomic or if fixation fails. PMID:25984515

    Abstract The aim of this study was to evaluate the survival benefit of palliative gastrectomy for gastric cancer patients with peritoneal seeding proven intraoperatively and to identify positive predictive factors for improving survival. The value of palliative resection for gastric cancer patients with peritoneal metastasis is controversial. From 2006 to 2013, 267 gastric cancer patients with intraoperatively identified peritoneal dissemination were retrospectively analyzed. Patients were divided into resection group and nonresection group according to whether a palliative gastrectomy was performed. Clinicopathologic variables and survival were compared. Subgroup analyses stratified by clinicopathologic factors and multivariable analysis for overall survival were also performed. There were 114 patients in the resection group and 153 in nonresection group. The morbidities in the resection and nonresection groups were 14.91% and 5.88%, respectively (P = 0.014). There, however, was no difference in mortality between the 2 groups. The median survival time of patients in the resection group was longer than in nonresection group (14.00 versus 8.57 months, P = 0.000). The median survivals among the patients with different classifications of peritoneal metastasis were statistically significant (P = 0.000). Patients undergoing resection followed by chemotherapy had a significantly longer median survival, compared with that of patients who had chemotherapy alone, those who had resection alone, or those who had not received chemotherapy or resection (P = 0.000). Results of subgroup analyses showed that except for P3 patients and patients with multisite distant metastases, overall survival was significantly better in patients with palliative gastrectomy, compared with the nonresection group. In multivariate analysis, P3 disease (P = 0.000), absence of resection (P = 0.000), and lack of chemotherapy (P = 0.000) were identified as independently

    A 68-year-old man underwent total gastrectomy and splenectomy for adenocarcinoma and low anterior resection for carcinoma in tubulo-villous adenoma of the rectum. Broad-spectrum antibiotics were administered for postoperative pancreatic fistula. Methicillin-resistant Staphylococcus aureus enteritis occurred on the 50th postoperative day and cecal perforation followed. The patient underwent construction of cecostomy with peritoneal drainage, and vancomycin was administered orally and per cecostomy for 2 weeks. The patient recovered well and was discharged at 35 days after re-operation in good general condition.

    Wernicke encephalopathy (WE) is a serious complication of bariatric surgery with significant morbidity and mortality. A few cases have been reported in the literature, mainly in patients after a Roux-en-Y gastric bypass. Since sleeve gastrectomy (SG) has become a more established and popular bariatric procedure, WE is expected to appear more frequently after SG. We performed a literature review on WE after SG, and 13 cases have been found to be sufficiently documented. The risk of WE needs to be considered in patients with a prolonged vomiting episode and any type of neurological symptoms, independent of the presence of any surgical complications.

    As the number of obese patients increases, as will the number of bariatric procedures. Malabsorptive bariatric procedures have emerged as one of common causes of Wernicke encephalopathy (WE), an acute neuropsychiatric disorder due to thiamine deficiency. However, restrictive procedures such as sleeve gastrectomy (SG) are less prone to cause nutrient deficiencies. WE occurred after SG is an uncommon complication because the main absorptive sites for thiamine are intact after SG. Here, we report a case of WE after SG. With rapid increase in the use of SG for morbid obesity, this case deserves particular attention from clinicians.

    The incidence of incidental pathology found during laparoscopic bariatric surgery has been estimated to be around 2%, and gastric gastrointestinal stromal tumors (GISTs) have been found in 0.8% of patients, constituting a rather uncommon finding. Safe laparoscopic resection of gastric GISTs is an established procedure and has been described associated to gastric Roux-en-Y bypass for morbid obesity. We discuss one case of a gastric GIST incidentally discovered during laparoscopic sleeve gastrectomy for morbid obesity. The procedure was performed via laparoscopy, and the patient recovered without any complication. Currently, the patient has lost weight according to what was expected, is asymptomatic, and free of disease.

    Sleeve gastrectomy is a relatively new procedure that developed as a result of rapid innovation in the field of bariatric surgery. As with any newly developed operation, there is a learning curve that potentially can be associated with higher morbidity. Real-time surgical mentoring reduces the learning curve effect but can be time intensive for the mentor. The aim of this initiative was to evaluate the feasibility, effectiveness, and satisfaction of surgical telementoring for laparoscopic sleeve gastrectomy. This is the first national specialty society effort to determine if the "remote presence" of an expert surgeon (mentor) can help practicing surgeons improve skills. The experience of 15 surgical trainees (mentees) who performed laparoscopic sleeve gastrectomy under real-time telementoring by 7 mentors was reviewed. Telementoring was implemented using the Visitor1(®) remote presence system with two-way live audio and video communication. The receiving platform utilized a conventional laptop, iPad, or iPhone. The mentee followed a structured telementoring program including didactic learning, live case teleobservation, and telementoring of 2-3 cases. A survey on the quality of the telecommunication and effectiveness of the mentoring was performed by the mentor and mentee on a scale of "exceeded," "met," "almost met," or "failed to meet" expectations. The overall telementoring experience was rated on a scale of 1 for "poor" to 5 for "excellent." Based on the mentees' survey, the overall telementoring experience was rated as 4.8. Despite the mentees having experience with laparoscopic sleeve gastrectomy, most commented that the telementoring experience was an excellent educational tool and they learned some new techniques they plan to apply it in their practice. Based on the mentors' survey, the overall telementoring experience was rated as 4.7. All mentors stated that they were satisfied with the telementoring sessions and there were no unexpected intraoperative

    Introduction Space analysis quantifies the amount of crowding within the arches estimating the severity of space discrepancy. The space gaining procedures include extraction and non-extraction procedures like expansion, proximal stripping and molar distalization. Aim To identify features seen in molar distalization cases. Materials and Methods The sample size comprised 20 patients in whom molar distalization was decided as the treatment plan. The study models and lateral cephalograms of all the patients were taken. Occlusograms were obtained. Model analysis and cephalometric analysis were performed. Descriptive statistical analysis like mean, standard deviation, standard error and mode were done. Results The parameters in Question gave following results. The Bolton analysis showed anterior mandibular excess with mean value of 1.56mm±1.07. The first order discrepancy between maxillary central and lateral incisors was 5±1.95. The premolar rotation showed mean value of 16.58±5.12. The molar rotation showed the value of 7.66±2.26. The nasolabial angle showed the mean of 101.25±8.7 IMPA of 101.4±5.74. Conclusion The six features studied in molar distalization cases [First order discrepancy between upper central and lateral incisors; Rotation of premolars and molars; Bolton’s discrepancy in anterior dentition; Average to horizontal growth pattern; Proclined lower incisors and Obtuse nasolabial angle] can be taken as patterns seen in molar distalization cases and considered as a valid treatment plan.

    During osteoarticular reconstruction of the distal radius with the proximal fibula, congruity between the two articular surfaces is an important factor in determining the quality of the outcome. In this study, a three-dimensional model and a coordinate transformation algorithm were developed on computed tomography scanning. Articular surface matching was performed and parameters for the optimal position were determined quantitatively. The mean radii of best-fit spheres of the articular surfaces of the distal radius and proximal fibula were compared quantitatively. The radial inclination and volar tilt following reconstruction by an ipsilateral fibula graft, rather than the contralateral, best resembles the values of the native distal radius. Additionally, the ipsilateral fibula graft reconstructed a larger proportion of the distal radius articular surface than did the contralateral. The ipsilateral proximal fibula graft provides a better match for the reconstruction of the distal radius articular surface than the contralateral, and the optimal position for graft placement is quantitatively determined.

    Since the launch of Earthdata in the later part of 2011, there has been an emphasis on improving the user experience and providing more enriched content to the user, ultimately with the focus to bring the "pixels to the people" or to ensure that a user clicks the fewest amount of times to get to the data, tools, or information which they seek. Earthdata was founded to be a single source of information for Earth Observing System Data and Information System (EOSDIS) components and services as a conglomeration between over 15 different websites. With an increased focus on access to Earth science data, the recognition is now on transforming Earthdata from a static website to one that is a dynamic, data-driven site full of enriched content.In the near future, Earthdata will have a number of components that will drive the access to the data, such as Earthdata Search, the Common Metadata Repository (CMR), and a redesign of the Earthdata website. The focus on content curation will be to leverage the use of these components to provide an enriched content environment and a better overall user experience, with an emphasis on Earthdata being "powered by EOSDIS" components and services.

    DNA copy number aberrations (CNAs) can be found in the majority of cancer genomes and are crucial for understanding the potential mechanisms underlying tumor initiation and progression. Since the first release in 2001, the Progenetix project (http://www.progenetix.org) has provided a reference resource dedicated to provide the most comprehensive collection of genome-wide CNA profiles. Reflecting the application of comparative genomic hybridization techniques to tens of thousands of cancer genomes, over the past 12 years our data curation efforts have resulted in a more than 60-fold increase in the number of cancer samples presented through Progenetix. In addition, new data exploration tools and visualization options have been added. In particular, the gene-specific CNA frequency analysis should facilitate the assignment of cancer genes to related cancer types. In addition, the new user file processing interface allows users to take advantage of the online tools, including various data representation options for proprietary data pre-publication. In this update article, we report recent improvements of the database in terms of content, user interface and online tools.

    Background. Palliative gastrectomy has been suggested to improve survival of patients with metastatic gastric cancer, but limitations in study design and availability of robust prognostic factors have cast doubt on the overall merit of this procedure. Methods. The characteristics and clinical outcomes of 173 patients diagnosed between 2008 and 2012 were analyzed to determine the value of palliative gastrectomy and to identify potential prognostic factors. Results. Median overall patient survival was 6.5 months. To attenuate potential selection bias, patients with adequate performance and survival time of ≥ 2 months since diagnosis were included for risk factor analysis (n = 137). The median overall survival was longer for patients who were younger than 60 years, had better performance status (8.7 versus 6.4 months, P = 0.015), received systemic chemotherapy, or had palliative gastrectomy in univariate analyses. Gastrectomy (P = 0.002) remained statistically significant in multivariate analyses. Subgroup analysis showed that patients aged < 60 years, CEA < 5 ng/mL or CA19-9 < 35 U/mL, obtained a survival advantage from palliative gastrectomy. In fact, palliative gastrectomy doubled overall survival for patients who had normal CEA and/or normal CA19-9. Conclusions. Palliative gastrectomy prolongs the survival of metastatic gastric cancer patients with normal CEA and/or CA19-9 level at the time of diagnosis. PMID:27990157

    Objective Attempts to treat class II malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. The purpose of this study was to investigate dental and skeletal effects of Bonded Molar Distalizer (BMD) which is a simple molar distalizing appliance. Materials and Methods Sixteen patients (12 girls, four boys) with bilateral half-cusp class II molar relationship, erupted permanent second molars and normal or vertical growth pattern were selected for bilateral distalization of maxillary molars via BMD. The screws were activated every other day, alternately. Lateral cephalograms and study models were obtained before treatment and after 11 weeks activation of the appliance. Results Significant amounts of molar distalization, molar distal tipping and anchorage loss were observed. The mean maxillary first molar distal movement was 1.22±0.936 mm with a distal tipping of 2.97±3.74 degrees in 11 weeks. The rate of distal movement was 0.48 mm per month. Reciprocal mesial movement of the first premolars was 2.26±1.12 mm with a mesial tipping of 4.25±3.12 degrees. Maxillary incisors moved 3.55±1.46 mm and tipped 9.87±5.03 degrees mesially. Lower anterior face height (LAFH) decreased 1.28±1.36 mm. Conclusion BMD is appropriate for distalizing maxillary molars, especially in patients with critical LAFH, although significant amounts of anchorage loss occur using this appliance. PMID:22457837

    Osteochondritis of the distal tibial epiphysis is a very rare entity. 9 cases have been described in 7 articles and 8 other cases have been mentioned in textbooks. This paper describes the 10th case of osteochondritis of the distal tibial epiphysis and summarizes the clinical and radiological presentations of the 9 other cases. The etiology of this entity is well debated in the literature. We believe that it results from a vascular abnormality in the distal tibial epiphysis associated with a mechanical stress (trauma, excessive overload, etc.). Since it is a self-limited disease, the prognosis is good and the younger the patient is the better the prognosis will be. In general, this entity responds well to conservative treatment.

    2014-06-01

    Fractures of the distal radius are among the most common pediatric fractures. Although most of these fractures heal without complication, some result in partial or complete physeal arrest. The risk of physeal arrest can be reduced by avoiding known risk factors during fracture management, including multiple attempts at fracture reduction. Athletes may place substantial compressive and shear forces across the distal radial physes, making them prone to growth arrest. Timely recognition of physeal arrest can allow for more predictable procedures to be performed, such as distal ulnar epiphysiodesis. In cases of partial arrest, physeal bar excision with interposition grafting can be performed. Once ulnar abutment is present, more invasive procedures may be required, including ulnar shortening osteotomy or radial lengthening.

    2008-01-01

    The incidence of distal radius fractures is increasing together with the average age of population. Intra-articular incongruity is the most probable cause of unsatisfactory outcome of distal radius fractures in younger and more active patients. Thus, the main goal in the treatment of distal radius fractures should be restoration of articular congruence. A computed tomography (CT) is recommended to help surgeon in preoperative planning in the treatment of comminuted intra-articular fractures. New implants have been designed to provide stable enough fixation for early mobilisation after surgery and to lower rather high complication rates related to conventional fixation methods such as external fixation and dorsal plating. The most common complications related to volar fixed angle plating such as flexor and extensor tendon problems, median nerve neuropathy, and screw diplacement into the radiocarpal joint are surgeon related and are avoidable with proper education. More randomized prospective studies are needed to prove superiority of any fixation method to another.

    It is well known that sodium reabsorption and aldosterone play important roles in potassium secretion by the aldosterone-sensitive distal nephron. Sodium- and aldosterone-independent mechanisms also exist. This review focuses on some recent studies that provide novel insights into the sodium- and aldosterone-independent potassium secretion by the aldosterone-sensitive distal nephron. In addition, we discuss a study reporting on the regulation of the mammalian potassium kidney channel ROMK by intracellular and extracellular magnesium, which may be important in the pathogenesis of persistent hypokalemia in patients with concomitant potassium and magnesium deficiency. We also discuss outstanding questions and propose working models for future investigation. PMID:21270092

    Distal humerus fractures are challenging injuries for the upper extremity surgeon. However, recent techniques in open reduction internal fixation have been powerful tools in getting positive outcomes. To get such results, the surgeon must be aware of how to properly use these techniques in their respective practices. The method of fixation depends on the fracture, taking the degree of comminution and the restoration of the columns and articular surface into account. This article helps surgeons understand the concepts behind open reduction internal fixation of the distal humerus and makes them aware of pitfalls that may lead to negative results.

    Primary urethral cancer is one of the rare urologic tumors. Distal urethral tumors are usually less advanced at diagnosis compared with proximal tumors and have a good prognosis if treated appropriately. Low-stage distal tumors can be managed successfully with a surgical approach in men or radiation therapy in women. There are no clear-cut indications for the choice of the most appropriate treatment modality. Organ-preserving modalities have shown effective and should be used whenever they do not compromise the oncological safety to decrease the physical and psychological trauma of dismemberment or loss of sexual/urinary function.

    Background The association between obesity and gastroesophageal reflux disease has a high incidence and may be present in half of obese patients with surgical indication. Bariatric operations can also induce reflux alone - differently from BMI factors - and its mechanisms are dependent on the type of procedure performed. Objective To perform a literature review comparing the two procedures currently most used for surgical treatment of obesity and analyze their relationship with the advent of pre-existing reflux disease or its appearance only in postoperative period. Method The literature was reviewed in virtual database Medline/PubMed, SciELO, Lilacs, Embase and Cochrane crossing the following MeSH descriptors: gastric bypass AND / OR anastomosis, Roux-en-Y AND / OR gastroesophageal reflux AND / OR gastroenterostomy AND / OR gastrectomy AND / OR obesity AND / OR bariatric surgery AND / OR postoperative period. A total of 135 relevant references were considered but only 30 were used in this article. Also was added the experience of the authors of this article in handling these techniques on this field. Conclusion The structural changes caused by surgical technique in vertical gastrectomy shows greater commitment of antireflux mechanisms predisposing the induction of GERD postoperatively compared to the surgical technique performed in the gastrointestinal Bypass Roux-en-Y.

    The need for partial gastrectomy has decreased as a result of reduced incidence and improved endoscopic and medical treatment of peptic ulcer disease. Nonetheless, several patients with resected stomach remain in the population, and it is well known that important pathological changes can occur in the gastric remnant. We evaluated the morphological and functional status of the gastric stump by use of modified endoscopic Congo red test (MCRT). For this purpose, 87 partially gastrectomized (Billroth I and II) patients referred for elective gastroscopy were consecutively enrolled. We found a high prevalence of severe chronic atrophic fundal gastritis (CAFG) (67%) in the gastric remnant. We also observed, however, that one-third of the patients had almost unaffected gastric acid production even as long as 26 years after partial gastrectomy. Moreover, the accuracy, sensitivity, and specificity of routine gastroscopy in diagnosing CAFG in the gastric stump were found to be 55%, 50%, and 84%, respectively. The presence of bile reflux correlated well with the degree of CAFG. Importantly, we observed that more than 71% of the patients receiving acid-suppressing therapy had no or very little capacity to produce gastric acid. Taken together, our study has demonstrated that MCRT is a simple and well-tolerated method providing important morphological and functional information about the mucosa of the resected stomach. Furthermore, MCRT was superior to routine gastroscopy in diagnosing CAFG in the gastric stump. Outcome studies should define the clinical benefit of MCRT in the management of patients with resected stomach.

    Previous studies have shown accelerated gastric emptying after sleeve gastrectomy. This study aimed to determine whether a correlation exists between immediate postoperative gastroduodenal transit time and weight loss after laparoscopic sleeve gastrectomy (LSG). Specifically, correlation tests were conducted to determine whether more rapid transit after LSG correlated with increased weight loss. Data were collected from an institutional review board-approved electronic registry. All LSGs were performed over a 40-Fr bougie, starting 5 to 7 cm proximal to the pylorus. Gastroduodenal transit time (antrum to duodenum) was calculated from a postoperative day 1 esophagram. Pearson's correlation coefficient was used for statistical analysis. The analysis included 62 consecutive LSG patients. The mean gastroduodenal transit time was 12.3 ± 19.8 s. Almost all the patients (99%) had a transit time less than 60 s. The mean percentage of excess weight loss (%EWL) was 23.8 ± 9.8% at 3 months, 37.9 ± 11.8% at 6 months, and 52.2 ± 10.8% at 12 months. No correlation was found between gastroduodenal transit time and %EWL at 3, 6, or 12 months. No correlation was found between gastroduodenal transit time and weight loss after LSG.

    AIM: To evaluate the prevalence and predictive factors of osteoporosis in patients with gastric adenocarcinoma after gastrectomy. METHODS: The study included 133 patients diagnosed with gastric adenocarcinoma but who did not undergo prior diagnostic work-up for osteoporosis. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DXA) and vertebral deformity was assessed by plain X-rays. We evaluated the effects of age, sex, body mass index (BMI), anemia, back pain, vertebral deformity, tumor staging, reconstruction type, and past medical history to determine predictive factors of osteoporosis in these patients. RESULTS: The prevalence of osteoporosis in the lumbar spine was 38.3% (male, 28.9%; female, 54.0%), and 15.0% in the femoral neck (male, 10.8%; female, 22.0%). The vertebral deformity rate was 46.6% (male, 43.4%; female, 52.0%). Age, BMI and hemoglobin correlated with BMD (P < 0.01). In males, anemia and age > 64 years were independent predictive factors of osteoporosis in multivariate analysis. In females, back pain was an independent factor for osteoporosis. CONCLUSION: The results of this study revealed that prevalence of osteoporosis and vertebral bone deformity rate were high in gastric cancer patients, regardless of post-gastrectomy duration and operation type. Early diagnosis and a proper management plan must be established in these patients. PMID:18161918

    This study examines relationships between gastrointestinal symptoms, uncertainty, and perceived recovery in gastric cancer patients after gastrectomy. Data were collected from 146 patients at an outpatient clinic of a university hospital in Seoul, Korea from October to November 2012. The Gastrointestinal Symptoms Rating Scale, the Mishel Uncertainty in Illness Scale, and questions on perceived recovery of physical, psychological, and social functions were analyzed. High gastrointestinal symptom scores were reported in women younger patients (F = 5.55, P = 0.005), and in patients without a family history of gastric cancer. The uncertainty score was higher in patients with low economic (F = 3.84, P = 0.024) and educational status and no family history. Regression analysis revealed uncertainty was the strongest factor associated with recovery. Nurses can assist patients and families to predict and deal with health problems by offering education on progress from diagnosis to postoperative management, promoting all aspects of recovery after gastrectomy.

    Laparoscopic proximal gastrectomy (LPG) has recently been applied for early gastric cancer (EGC) in the upper stomach as a minimally invasive and function-preserving surgery. This study aimed to clarify the feasibility and nutritional benefits of LPG over laparoscopic total gastrectomy (LTG). This was a retrospective study of 77 patients with clinical stage I gastric cancer in the upper stomach. Of these patients, 25 underwent LPG, while 52 underwent LTG. Surgical outcomes and postoperative nutritional status such as changes in body weight and blood chemistries were compared between LPG and LTG. Intraoperative blood loss and C-reactive protein levels at 3 and 7 days after surgery were significantly lower in LPG than in LTG (p = 0.018, 0.036, and 0.042, respectively). No significant differences were observed in postoperative early or late complication rates between LPG and LTG. The incidence of Los Angeles Grade B or more severe reflux esophagitis after LPG was 9.1 %, which was similar to that after LTG (9.3 %). Postoperative changes in body weight at 6 months and 1 and 2 years after surgery were consistently less in LPG than in LTG (p = 0.001, 0.022, and 0.001, respectively). Moreover, postoperative levels of hemoglobin and serum albumin and total lymphocyte count were also higher in LPG than in LTG. LPG may be a better choice for EGC in the upper stomach than LTG because it has distinct advantages in terms of surgical invasiveness and postoperative nutritional status.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P < 0.001), compared with nonsarcopenic patients. The multivariate analysis demonstrated that sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P < 0.001) and the Charlson comorbidity index ≥2 (odds ratio: 3.357, 95% CI: 1.144-9.848, P = 0.027) were independent risk factors for postoperative complications. Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    There remains debate as to whether quality of life (QoL) is better for patients following sub-total gastrectomy (SG) or total gastrectomy (TG) for cancer. Both have similar survival rates provided an R0 resection is performed and in many series the morbidity and mortality after TG is higher than SG. The aim of this study was to evaluate the QoL in patients after TG and SG for cancer. All surviving patients who had undergone TG or SG between 1994 and 2009 were identified from a prospectively collected database and sent the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire (QLQ-C30 v.3) and the gastric module (QLQ-STO22). From a total of 261 patients who had undergone TG or SG in the study period, 91 were still alive and 53 responded. There was no significant difference between the QoL between TG and SG based on functional scales and global health status. However dysphagia and eating restrictions were significantly worse in the TG group. This study has demonstrated that there is no difference in overall QoL in patients with TG or SG although eating restrictions and dysphagia are worse after TG.

    LigaSure™ was developed as an alternative to suture ligatures, hemoclips and staplers for ligating vessels and tissue bundles. The aim of the present study was to determine whether LigaSure can be used as a welding instrument in the performance of laparoscopic sleeve gastrectomy. Gastric specimens were assigned into four groups. Group 1 - specimens remained with the staple line intact. Group 2 - the staple line was oversewn. Group 3 - the staple line was resected with LigaSure. Group 4 - staple line was resected with LigaSure and the seal was oversewn. In all specimens the pressure tolerance was assessed using a portable sensor. In group 1 the leak pressure was 34.7 ± 11.7 whereas in group 2 specimens the pressure increased three-fold (101.9 ± 21.4). The LigaSure seal alone (group 3) achieved a mean pressure of 13.7 mmHg. However, in group 4 there was an exponential increase on their burst strength up to 142 mmHg (p = 0.0005). According to our results, LigaSure could be used to perform laparoscopic sleeve gastrectomy with reduction of staple-line bleeding and, when reinforced with a running suture, it achieves a strength that approaches that of staples plus oversewing.

    Background The complete blood count (CBC) and C-reactive protein (CRP) are useful inflammatory parameters for ruling out acute postoperative inflammatory complications. Aim To determine their changes in gastric cancer patients submitted to total gastrectomy. Methods This is a prospective study, with 36 patients with gastric cancer who were submitted to elective total gastrectomy. On the first, third and fifth postoperative day (POD), blood count and CRP changes were assessed. Patients with postoperative complications were excluded. Results Twenty-one (58%) were men and 15 (42%) women. The mean age was 65 years. The leukocytes peaked on the 1st POD with a mean of 13,826 u/mm³, and decreased to 8,266 u/mm³ by the 5th POD. The bacilliforms peaked on the 1st POD with a maximum value of 1.48%. CRP reached its maximum level on the 3rd POD with a mean of 144.64 mg/l±44.84. Preoperative hematocrit (HCT) was 35% and 33.67% by the 5th POD. Hemoglobin, showed similar values. Conclusions Leukocytes increased during the 1st POD but reached normal values by the 5th POD. CRP peaked on the 3rd POD but did not reach normal values by the 5th POD. PMID:25626929

    Introduction Sleeve gastrectomy (SG) is a frequently used surgical procedure for the treatment of morbid obesity. Several complications of SG have been described; however, de novo hiatal hernia of the gastric tube, as a complication of SG, has not been described in the literature. Presentation of case Here, we report a case of a hiatal hernia 2 years after SG. In the case reported here, the hiatal hernia was associated with weight regain. The mechanisms responsible for the herniation of the pouch are difficult to identify. Conversion from sleeve gastrectomy to Roux-en-Y gastric bypass is an effective treatment for this complication. Its management is safe and effective. Discussion Obesity itself is an independent risk factor for hiatal hernia, found preoperatively in more than half of the morbidly obese patients. This predisposition is explained by higher intra-gastric pressure due to intra-abdominal or visceral fat, reduced inferior oesophageal sphincter pressure, and oesophageal motility problems. Conclusion To our knowledge, this is the first described case of hiatal hernia of the gastric tube after SG. PMID:26318133

    Introduction Good results have been published by researchers with distal femur nail, dynamic condylar screw and even addition of a medial plate to a distal femur locking plate for treating distal femur fractures. By this study, we explore the capability of a distal femur locking plate to counter distal femur fractures of extra- articular, partial or intra- articular nature. Positive results have been published by various groups from all over the world. Aim To study the functional and radiological outcome of distal femoral fractures in skeletally mature patients treated by open reduction and internal fixation with distal femur locking plate. Materials and Methods This was a prospective study conducted from January 2012 to March 2014 at the Government Medical College and Hospital (GMCH) with a 2 year follow-up. Twenty five skeletally mature patients with post-traumatic distal femur fractures were included. Patients with open grade 3B and 3C distal femur fractures, according to the Gustilo- Anderson classification and pathological distal femur fractures were excluded from the study. Patients with any fracture other than the distal femur in the ipsilateral limb were excluded from the study. Follow-up at 3 months, 6 months, 1 year and 2 years was carried out and evaluation was done according to the Neer scoring system. The statistical data analysis was carried out using SPSS version 20 (IBM, Chicago, USA). The p-value <0.05 was considered significant. Results Following all principles of fracture reduction, union was achieved in all patients with mean time to radiological union being 19 weeks. The mean Range of Motion (ROM) was 109 degrees with 20 patients having a Neer score graded as excellent to satisfactory. Our study had nine cases which required additional surgeries. Out of these, all nine cases required bone grafting, three also required antibiotic cement bead insertion initially. Three patients developed complications in the form of infection (two cases) and mal

    The distal radioulnar ligament reconstruction is a technique that may be used for distal radioulnar joint instability without arthritis and failed nonsurgical management; clinical results demonstrate resolved or improved stability. Recent literature has focused on the distal oblique bundle of the interosseous membrane and its contributions to stability. This article describes a technically simple surgical technique to reconstruct the distal oblique bundle and restore distal radioulnar joint stability.

The purpose of this study is to accurately characterize the perioperative outcomes of a resident teaching model using the robotic-assisted sleeve gastrectomy. University Hospital. We identified 411 consecutive patients who underwent robotic sleeve gastrectomy at our institution from a prospectively maintained administrative database. Perioperative morbidity, operative time, and supply cost of the procedure were analyzed. Mean operative time was 96.4±24.9 minutes; mean robot usage time was 63.9 minutes (range 30.0-122.0 min). Ninety-day morbidities included reoperation (0.72%), major bleeding complications (0.48%), staple line leak (0.24%), stricture (0.97%), need for blood transfusion (3.86%), surgical site infection (1.69%), deep vein thrombosis (0.48%), and pulmonary embolism (0.48%). Mortality was nil. The resident cohort achieved operative time plateaus after five consecutive cases. Subset analysis for fiscal year 2014 demonstrated significantly increased supply cost for robotic sleeve gastrectomy compared with its laparoscopic equivalent. Robotic-assisted sleeve gastrectomy can be instituted as a model for resident robotic education with rates of morbidity and operative times equivalent to historical laparoscopic controls. The robot's enhanced ergonomics and its opportunity for resident education must be weighed against its increased supply cost. Copyright © 2016 American Society for Bariatric Surgery.

    Gastrectomy/gastric bypass has been used for patients with gastric cancer, and its application is now expanding to treating patients with morbid obesity, the prevalence of which is increasing worldwide. It is well known that gastrectomy leads to osteopenia, but the underlying pathophysiology and optimum treatments for this disorder have not been delineated. We followed 13 patients who showed progressive osteopenia (bone mineral density T-score<-2.4 SD) after gastrectomy/gastric bypass due to gastric cancer and who were resistant to long-term treatment (mean, 6 years) of active vitamin D3 and prospectively studied the effects of alendronate, a bisphosphonate, on osteopenia-related parameters for 2 years. Oral administration of alendronate in addition to vitamin D3 led to remarkable improvement within 2 years, not only in clinical symptoms, such as radial bone fractures and lumbar pain, but also in parameters for osteopenia, including decreased bone mineral density of the lumbar spine (P<0.01), decreased concentrations of calcium (P<0.05), increased urine levels of deoxypyridinoline (P<0.01), increased serum levels of bone-specific alkaline phosphatase (P<0.01), increased serum levels of osteocalcin (P<0.01), and increased serum levels of intact parathyroid hormone (P<0.05), although body weight did not alter. These results suggest that bisphosphonate may improve osteopenia after gastrectomy/gastric bypass.

    The ultrasonic Harmonic scalpel has demonstrated clinical and surgical benefits in dissection and coagulation. To evaluate its use in gastrectomy, we conducted a systematic review and meta-analysis of randomized controlled trials comparing the Harmonic scalpel to conventional techniques in gastrectomy for patients with gastric cancer. International databases were searched without language restrictions for comparisons in open or laparoscopic gastrectomy and lymphadenectomy. The meta-analysis used a random-effects model for all outcomes; continuous variables were analyzed for mean differences and dichotomous variables were analyzed for risk ratios. Sensitivity analyses were conducted for study quality, type of conventional technique, and imputation of study results. Ten studies (N = 935) met the inclusion criteria. Compared with conventional hemostatic techniques, the Harmonic scalpel demonstrated significant reductions in operating time (-27.5 min; P < 0.001), intraoperative blood loss (-93.2 mL; P < 0.001), and drainage volume (-138.8 mL; P < 0.001). Results were numerically higher for conventional techniques for hospital length of stay, complication risk, and transfusions but did not reach statistical significance. Results remained robust to sensitivity analyses. This meta-analysis demonstrates the clear advantages of using the Harmonic scalpel compared to conventional techniques, with improvements demonstrated across several outcome measures for patients undergoing gastrectomy and lymphadenectomy.

  20. Text Mining to Support Gene Ontology Curation and Vice Versa.

    In this chapter, we explain how text mining can support the curation of molecular biology databases dealing with protein functions. We also show how curated data can play a disruptive role in the developments of text mining methods. We review a decade of efforts to improve the automatic assignment of Gene Ontology (GO) descriptors, the reference ontology for the characterization of genes and gene products. To illustrate the high potential of this approach, we compare the performances of an automatic text categorizer and show a large improvement of +225 % in both precision and recall on benchmarked data. We argue that automatic text categorization functions can ultimately be embedded into a Question-Answering (QA) system to answer questions related to protein functions. Because GO descriptors can be relatively long and specific, traditional QA systems cannot answer such questions. A new type of QA system, so-called Deep QA which uses machine learning methods trained with curated contents, is thus emerging. Finally, future advances of text mining instruments are directly dependent on the availability of high-quality annotated contents at every curation step. Databases workflows must start recording explicitly all the data they curate and ideally also some of the data they do not curate.

    Most currently available glycan structure databases use their own proprietary structure representation schema and contain numerous annotation errors. These cause problems when glycan databases are used for the annotation or mining of data generated in the laboratory. Due to the complexity of glycan structures, curating these databases is often a tedious and labor-intensive process. However, rigorously validating glycan structures can be made easier with a curation workflow that incorporates a structure-matching algorithm that compares candidate glycans to a canonical tree that embodies structural features consistent with established mechanisms for the biosynthesis of a particular class of glycans. To this end, we have implemented Qrator, a web-based application that uses a combination of external literature and database references, user annotations and canonical trees to assist and guide researchers in making informed decisions while curating glycans. Using this application, we have started the curation of large numbers of N-glycans, O-glycans and glycosphingolipids. Our curation workflow allows creating and extending canonical trees for these classes of glycans, which have subsequently been used to improve the curation workflow. PMID:25165068

    Background: Novel in vitro methods are being developed to identify chemicals that may interfere with estrogen receptor (ER) signaling, but the results are difficult to put into biological context because of reliance on reference chemicals established using results from other in vitro assays and because of the lack of high-quality in vivo reference data. The Organisation for Economic Co-operation and Development (OECD)-validated rodent uterotrophic bioassay is considered the “gold standard” for identifying potential ER agonists. Objectives: We performed a comprehensive literature review to identify and evaluate data from uterotrophic studies and to analyze study variability. Methods: We reviewed 670 articles with results from 2,615 uterotrophic bioassays using 235 unique chemicals. Study descriptors, such as species/strain, route of administration, dosing regimen, lowest effect level, and test outcome, were captured in a database of uterotrophic results. Studies were assessed for adherence to six criteria that were based on uterotrophic regulatory test guidelines. Studies meeting all six criteria (458 bioassays on 118 unique chemicals) were considered guideline-like (GL) and were subsequently analyzed. Results: The immature rat model was used for 76% of the GL studies. Active outcomes were more prevalent across rat models (74% active) than across mouse models (36% active). Of the 70 chemicals with at least two GL studies, 18 (2
