    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.

    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

    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.

    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

    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

    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

    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.”

    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

    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

    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

    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.

    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.

    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.

    We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. 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.

    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.

    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.

    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

    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.

    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

    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.

    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

    During the last two years, reports on laparoscopic procedures of the pancreas have been on increase. Laparoscopic resection of the pancreatic cauda is indicated, primarily, for benign cystic lesions of the cauda of the pancreas and for neuroendocrine tumors of the pancreas (mainly insulinomas). We have not recorded any report on the above procedure in the Czech literature. Therefore, in our case review, we have described laparoscopic distal resection of the pancreas with splenectomy for a pseudopapillary tumor of the pancreas.

    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

    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

    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.

    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

    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.

    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.

    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).

    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.

    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

    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.

    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.

    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.

  18. Reconstruction of the esophagojejunostomy by double stapling method using EEA™ OrVil™ in laparoscopic total gastrectomy and proximal gastrectomy

    PubMed Central

    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

    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

    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.

    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

    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.

    Minimally invasive, laparoscopic gastrectomy (LG) has assumed an ever-expanding role in gastric cancer treatment. Accumulating data so far seem to suggest that LG is at least a viable alternative of conventional open gastrectomy (OG) in different contexts. However, even though reviews and meta-analyses have compared the advantages and limitations of each option, it is still controversial whether LG is a better alternative to OG, especially in advanced gastric cancer (AGC). The major goal of this study is to evaluate the readouts of LG, in comparison with OG. A literature search was performed for studies published from 2009 to 2013. Medical records of 20868 gastric cancer patients from 32 independent studies were reviewed and analyzed. All 32 studies concluded that LG is at least comparable with OG. LG is superior to OG in offering less blood loss, shorter hospital stay, and lower risk of complications, although LG is probably inferior in operative time, and not different from OG in mortality. Considering the merits and the potential future technical improvement, it is reasonable to speculate that LG may eventually replace OG in most clinical contexts. PMID:26379823

    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.

    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.

    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.

    Purpose To present the feasibility and safety of Roux-en-Y esophagojejunostomy using hemi-double-stapling technique after laparoscopic total gastrectomy. Methods We reviewed the outcomes from 58 consecutive patients with gastric cancer who underwent laparoscopic total gastrectomy. The clinicopathological characteristics including postoperative complications were examined. Results The mean age and body mass index were 57.3 ± 9.7 years and 23.7 ± 2.6 kg/m2, respectively. The mean overall total operation was 199.8 ± 57.0 minutes. Intraoperative blood loss was 81.6 ± 56.3 mL and there was no open conversion. The patients' hospital stay was a mean 9.6 ± 2 days. The mean proximal margin of the specimens was 2.7 ± 1.8 cm. There were 3 cases (5.1%) of anastomosis leakage, but all were controlled successfully by endoscopic stent. Conclusion The circular HDST technique is simple and reliable without any significant demerits with respect to safety concerns or difficulty of operation. PMID:28090503

    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

    Laparoscopic sleeve gastrectomy (LSG) as a single-stage restrictive bariatric procedure is becoming increasingly popular, especially in patients who are high risk and/or superobese. Between November 21, 2006, and September 30, 2008, 42 patients underwent LSG at our institution. Average age was 47 +/- 11 years, average body mass index was 54 +/- 10 kg/m2, and 62 per cent were female. Preoperative indications for LSG included contraindication to laparoscopic Roux-en-Y gastric bypass (n = 11), severe coronary artery disease and/or congestive heart failure (n = 3), significant liver disease (n = 3), and patient preference (n = 4). Intraoperative indications for LSG included a foreshortened mesentery with inability to create a gastrojejunostomy (n = 13), extensive adhesions (n = 5), and intraoperative findings concerning for cirrhosis (n = 3). Twelve complications occurred in six patients: laparoscopic to open conversion (n = 1), reoperation (n = 3), nosocomial pneumonia (n = 1), wound infection (n = 1), bleeding (n = 1), pulmonary embolus (n = 1), readmission (n = 3), and superior splenic pole infarction. There was one death resulting from pulmonary embolism that occurred 2 weeks postoperatively. Preliminary excess body weight loss at 3, 6, 9, and 12 months was 29, 32 t, 38, and 30 per cent, respectively, and many patients had improvement or resolution of obesity-related comorbidities. Early review of our experience demonstrates that LSG may be an effective single-stage bariatric procedure. Additional follow up will be necessary to better define its long-term safety and efficacy.

    BACKGROUND: Laparoscopic sleeve gastrectomy (SG) has gained popularity and acceptance among bariatric surgeons, mainly due its low morbidity and mortality. Single-incision laparoscopic surgery has emerged as another modality of carrying out the bariatric procedures. While the single-incision transumbilical (SITU) approach represents an advance, especially for cosmetic reasons, its application in morbid obesity at present is limited. We describe our short-term surgical results and technical considerations with SITU-SG. MATERIALS AND METHODS: SITU-SG was performed in 10 patients between June 2010 and June 2011. SG was performed in a standard fashion and was started 6 cm from the pylorus using a 36 French bougie. RESULTS: They were all females with a mean age of 45 years. Preoperative BMI was 40 kg/m2 (range, 35–45). The mean operative time was 98 min. No peri- or postoperative complications or deaths occurred. All patients were very satisfied with the cosmetic outcomes and excess weight loss. CONCLUSION: True SITU laparoscopic SG is safe and feasible and can be performed without changing the existing principles of the procedure. PMID:24019687

    Background Surgery remains the mainstay of gastric cancer treatment. It is, however, associated with a relatively high risk of perioperative complications. The use of laparoscopy and the Enhanced Recovery After Surgery (ERAS) protocol allows clinicians to limit surgically induced trauma, thus improving recovery and reducing the number of complications. The aim of the study is to present clinical outcomes of patients with gastric cancer undergoing laparoscopic gastrectomy combined with the ERAS protocol. Material/Methods Fifty-three (21 female/32 male) patients who underwent elective laparoscopic total gastrectomy due to cancer were prospectively analyzed. Demographic and surgical parameters were assessed, as well as the compliance with ERAS protocol elements, length of hospital stay, number of complications, and readmissions. Results Mean operative time was 296.4±98.9 min, and mean blood loss was 293.3±213.8 mL. In 3 (5.7%) cases, conversion was required. Median length of hospital stay was 5 days. Compliance with ERAS protocol was 79.6±14.5%. Thirty (56.6%) patients tolerated an early oral diet well within 24 h postoperatively; in 48 (90.6%) patients, mobilization in the first 24 hours was successful. In 17 (32.1%) patients, postoperative complications occurred, with 7 of them (13.2%) being serious (Clavien-Dindo 3-5). The 30-day readmission rate was 9.4%. Conclusions The combination of laparoscopy and the ERAS protocol in patients with gastric cancer is feasible and allows achieving good clinical outcomes. PMID:28331173

    2015-09-01

    Background: Some institutions and insurance companies mandate a preoperative weight loss regimen prior to bariatric surgery. Previous studies suggest little to no correlation between preoperative and postoperative weight loss for laparoscopic Roux-en-Y gastric bypass (RNYGB). This study examined the impact of preoperative weight change for patients undergoing laparoscopic sleeve gastrectomy (LSG). Materials and Methods: A retrospective analysis was performed on patients undergoing LSG at the authors' institution from 2010 to 2012. Patients were grouped based on preoperative weight gain or loss. The correlation between preoperative BMI change and postoperative BMI change was studied, as well as length of surgery. Results: Of 141 patients with 1-year follow-up, 72 lost, six maintained, and 64 gained weight preoperatively. Percentage of excess BMI loss at 1 year was not statistically different between those who lost weight and those who gained weight. Percent change in BMI from initial visit to surgery does not correlate with change in BMI at 1 year postoperatively or with length of surgery. Conclusions: Preoperative weight loss is not a reliable predictor of postoperative weight loss or shorter operative time after LSG. Potential patients who otherwise meet indications for LSG should not be denied based on inability to lose weight.

    Objective The aim of this study was to evaluate the Laparoscopic Sleeve Gastrectomy (LSG) with simultaneous crural repair in treatment of morbid obesity associated with gastroesophageal reflux disease. Methods This prospective observational study was carried out from September 2012 to July 2016 in Al-Azhar University Hospital (Egypt). The study was conducted on 53 patients, 14 males (26.4%) and 39 females (73.6%) with the mean age 36.2 years (range 18–52 years), presenting with morbid obesity and reflux disease either symptomatic patients or asymptomatic (Endoscopic & Manometric), their mean Body Mass Index (BMI) was 50.1 kg/m2 (range 40–62 kg/m2), who underwent LSG and antireflux procedure (crural repair). Results Excess weight Loss (EWL); the mean EWL at 6 months postoperatively was 46.3%, at 12 months was 54%, and at 18 months was 61%. Also, we found that, preoperative co-morbidities are resolved by 53% and improved by 23%. Reflux symptoms were absent in 30 patients (56 %), improved in 14 patients (26.4 %), but persistent in 7 patients (13.2 %). Conclusion Laparoscopic crural closure, during LSG, represents a valuable option for the treatment of morbid obesity and gastroesophageal reflux, and can result in favorable outcomes in terms of weight loss and gastroesophageal reflux disease (GERD) symptoms control.

    In recent times, pediatric obesity has become widely prevalent. If first-line treatment with lifestyle modification fails, bariatric surgery may be indicated for severely obese patients. Many patients now travel abroad to get these surgeries done. Some of these patients receive inadequate postoperative care. We described a morbidly obese 17-year-old girl who had a laparoscopic sleeve gastrectomy procedure for weight loss. Due to severe nausea, she stopped her multivitamin supplementation. Within a few weeks, she developed symptoms of dry beriberi was soon followed by classic symptoms of Wernicke's encephalopathy. The prompt diagnosis was made with confirmation from serum thiamine level and brain magnetic resonance imaging. Thiamine supplementation reversed ophthalmological symptoms promptly. However, the patient needed inpatient rehabilitation for neuropathy. This case describes that thiamine deficiency can occur after restrictive bariatric surgery, despite lower risk of malnutrition in the absence of intestinal bypass procedure. This report highlights that in the presence of risk factors: dietary noncompliance, inadequate follow-up, and severe nausea with and without vomiting can precipitate the development of Wernicke's encephalopathy, even after restrictive surgery. Physicians may increasingly encounter thiamine and other nutrient deficiencies in increasing numbers due to increasing prevalence of obesity disorders and availability of bariatric surgeries. This report also emphasized the importance of identifying vague sensory symptoms in thiamine deficiency. PMID:26557183

    Objective Laparoscopic sleeve gastrectomy (LSG) is a popular bariatric surgery due to its excellent results and limited morbidity. Our study aims to assess the efficacy of LSG in terms of loss of weight and co-morbidity improvement and to evaluate the impact of preoperative body mass index (BMI) on the final outcome. Material and Methods The data of 173 patients who underwent LSG were analyzed. Laparoscopic sleeve gastrectomy was indicated only for patients with BMI >40. Mean postoperative BMI, co-morbidity improvement, operative data and complications, length of hospital stay and excess weight loss were evaluated and recorded. Results This study included 151 females and 22 males with a mean age of 37.6 years. Patients were divided into two groups according to their BMI (group I <50, group II >50). Mean preoperative BMI was 53.8 kg/m2. Mean operative time was 120 minutes. Mean duration of hospital stay was 3.2 days. Mean postoperative BMI decreased to 47.3 kg/m2 at 1 year. Excess weight loss was 43.1% at 6 months, 71.1% at 1 year, and 87.5% at 5 years. Group I showed a significantly shorter length of hospital stay, more improvement of laboratory parameters and more reduction in BMI as compared to group II. There was one mortality and six cases had gastric staple line leakage. Conclusion Laparoscopic sleeve gastrectomy is an efficient treatment to achieve significant weight loss that is maintained up to 5 years of follow up, also it improves some of the obesity related co-morbidities. This beneficial impact of LSG appears to be significantly higher in patients with BMI <50. PMID:28149118

    This study aimed to assess the relationship between the metabolic effect after laparoscopic sleeve gastrectomy (LSG) in morbidly obese Japanese patients, with or without type 2 diabetes mellitus (T2DM), and improved pancreatic steatosis (PS). The study enrolled 27 morbidly obese Japanese patients who were undergoing LSG. Their clinical and metabolic effects were evaluated at baseline and six months after LSG. Pancreas volume (PV), pancreatic attenuation (PA), and splenic attenuation (SA) were measured using a 64-row computed tomography (CT). Changes in PV, PA-SA, and PA/SA were evaluated. The mean body-weight loss, body mass index loss, and percentage of excess weight loss (%EWL) were -34.4 kg (p < 0.001), -11.0 kg/m(2) (p < 0.001), and 43.7%, respectively. The mean PV was 96.7 mL at baseline, and it decreased six months after LSG (-16.3mL, p < 0.001). The mean PA significantly increased six months after LSG (9.5 HU, p < 0.001). PA-SA (-23.2 HU vs. -13.3 HU, p = 0.003), and PA/SA (0.54 vs. 0.73, p < 0.001) also significantly increased six months after LSG. In T2DM patients, decreased PV correlated with decreased fasting blood sugar, decreased insulin, and reduced liver volume. In conclusion, PV significantly decreased after LSG in morbidly obese Japanese patients, and that decrease correlated with improvements in PS. In addition, PS plays an important role of development and progression of insulin resistance and T2DM.

    Introduction Laparoscopic sleeve gastrectomy (LSG) is one of the most popular bariatric procedures. The procedure is associated with serious staple-line complications such as bleeding, leaks, and stenosis. Aim To determine whether oversewing the staple line, compared with clipping, in LSG reduces the incidence of postoperative bleeding. Material and methods We conducted a parallel-group, prospective, randomized controlled trial (RCT) of 100 patients who underwent LSG for obesity at a single institution between May 2014 and August 2015. Patients were assigned to one of two groups for reinforcement of the staple line: the oversewing group (staple line oversewn) or the clipping group (staple line clipped). The primary outcome was reoperation for hemodynamic instability caused by staple-line bleeding within 72 h postoperatively. The secondary outcomes were operative duration, length of hospital stay, postoperative leaks, and postoperative stenosis. Results Mean operative duration was longer in the oversewing group (78.2 ±20.5 min) than in the clipping group (64.1 ±16.5 min, p < 0.001). Mean length of hospital stay was comparable in both groups. Postoperatively, there was no significant between-group difference in bleeding (oversewing, n = 0 vs. clipping, n = 2 (4.6%); p = 0.21) or in stenosis and leakage (both outcomes: oversewing, n = 0, vs. clipping, n = 1 (2.3%); p = 0.46). Conclusions Oversewing the staple line prolongs operative duration. No conclusions can be drawn regarding the effects of oversewing on staple-line bleeding, postoperative leakage and stenosis, or length of hospital stay. PMID:27829937

    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.

    2017-01-01

    OBJECTIVE: The purpose of this meta-analysis is to compare the short-term outcomes between experienced robotic gastrectomy (RG) and laparoscopic gastrectomy (LG). MATERIALS AND METHODS: We searched the PubMed, Springer Link, Elsevier, and Embase databases for articles published in English before June 2015 using an electronic literature search and including cross-referenced articles. Three studies were eligible for the meta-analysis. The outcomes evaluated were operation time, estimated blood loss, harvested lymph nodes, complication, and postoperative hospital stay. RESULTS: Of a total of 562 patients, 165 underwent RG and 397 underwent LG. Operation time was significantly longer in the RG group [weighted mean difference (WMD): 21.49, 95% confidence interval (CI): 12.48-30.50, P < 0.00001). Estimated blood loss, harvested lymph nodes, complication, and postoperative hospital stay were similar between the two groups. CONCLUSION: Experienced RG has similar short-term outcomes to LG that is performed by sophisticated laparoscopic surgeons, except for operation time. PMID:27251844

    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.

    Purpose. To investigate changes in optical coherence tomography parameters in morbidly obese patients who had undergone laparoscopic sleeve gastrectomy (LSG). Methods. A total of 41 eyes of 41 morbidly obese patients (BMI ≥ 40) who had undergone LSG were included in study. The topographic optic disc parameters, central macular thickness (CMT), total macular volume (TMV), and retinal ganglion cell layer (RGCL) were measured by spectral-domain optical coherence tomography (SD-OCT). Subfoveal choroidal thickness (SFCT) was measured by enhanced deep imaging-optical coherence tomography (EDI-OCT). Results. The mean CMT was 237.4 ± 24.5 μm, 239.3 ± 24.1 μm, and 240.4 ± 24.5 μm preoperatively, 3 months postoperatively, and 6 months postoperatively, respectively (p < 0.01). The mean TMV was 9.88 ± 0.52 mm3, 9.96 ± 0.56 mm3, and 9.99 ± 0.56 mm3 preoperatively, 3 months postoperatively, and 6 months postoperatively, respectively (p < 0.01). The mean RGCL was 81.2 ± 6.5 μm, 82.7 ± 6.6 μm, and 82.9 ± 6.5 μm preoperatively, 3 months postoperatively, and 6 months postoperatively, respectively (p < 0.01). The mean SFCT was 309.8 ± 71.8 μm, 331.0 ± 81.4 μm, and 352.7 ± 81.4 μm preoperatively, 3 months postoperatively, and 6 months postoperatively, respectively (p < 0.01). No statistically significant differences were found between the preoperative values and 3- and 6-month postoperative values in rim area (p = 0.34), disc area (p = 0.64), vertical cup/disc ratio (p = 0.39), cup volume (p = 0.08), or retinal nerve fiber layer (p = 0.90). Conclusions. Morbidly obese patients who undergo LSG experience a statistically significant increase in CMT, TMV, SFCT, and RGCL at 3 months and 6 months after surgery. PMID:27413543

    Abstract Background: The distal splenorenal shunt is an effective procedure for the treatment of portal hypertension in children. However, there has been no report about laparoscopic distal splenorenal shunt in the treatment of portal hypertension in children. Methods: From December 2015 to August 2016, 4 children with upper gastrointestinal bleeding underwent laparoscopic distal splenoadrenal shunt. Portal hypertension and splenomegaly were demonstrated on the preoperative computed tomography (CT) and sonography. The distal splenic vein was mobilized and anastomosed to the left adrenal vein laparoscopically. All patients were followed-up postoperatively. Results: The laparoscopic distal splenoadrenal shunt was successfully performed in all patients. The liver fibrosis was diagnosed by postoperative liver pathology. The operative time ranged from 180 to 360 minutes. The blood loss was minimal. The length of hospital stay was 6 to 13 days. The duration of following-up was 1 to 9 months (median: 3 months). The portal pressure and splenic size were decreased postoperatively. The complete blood count normalized and the biochemistry tests were within normal range after surgery. Postoperative ultrasound and CT confirmed shunt patency and satisfactory flow in the splenoadrenal shunt in all patients. No patient developed recurrence of variceal bleeding. Conclusions: The laparoscopic splenoadrenal shunt is a feasible treatment of portal hypertension in children. PMID:28099341

    The mechanisms involved in the weight loss seen after vertical sleeve gastrectomy (VSG) are not clear. The rat stomach has two morphologically and functionally distinct proximal and distal parts. 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

    Laparoscopic distal pancreatectomies became more common in the past few years as a safe and effective treatment option for benign and low-grade malignant tumors of the body and tail of the pancreas. Adequate exposure and wide operative field are crucial to perform this procedure, and this is achieved by retraction of the stomach with an angled liver retractor or a grasper through a subxiphoid trocar, that is usually used only to this purpose. We developed an innovative technique to retract the stomach during laparoscopic distal pancreatectomies that provides excellent operative field and frees the subxiphoid trocar to be used in other tasks during the surgery.

    In kidney transplantation, obesity is associated with poorer graft survival and patient survival. Bariatric surgery may provide benefit for these patients, not only by inducing weight loss, but also via reduction of diabetes. We report a case of morbid obesity, poorly controlled new-onset diabetes mellitus, and gout after kidney transplantation that was treated with laparoscopic sleeve gastrectomy 3 years after kidney transplantation. After 1 year of follow-up, 76% excessive body weight loss was attained. No complications were noted. The operation also provided total remission of diabetes and gout as well as good graft survival. Based on our experience, laparoscopic sleeve gastrectomy may be a feasible treatment for obese patients after renal transplantation to help resolve obesity and control new-onset diabetes. However, the timing of operation and the long-term potential for graft and patient survivals with this operation require further study.

    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

    Obesity is a major worldwide problem in public health, reaching epidemic proportions in many countries, especially in urbanized regions. Bariatric procedures have been shown to be more effective in the management of morbid obesity, compared to medical treatments in terms of weight loss and its sustainability. The two most commonly performed procedures are laparoscopic Roux-en-Y gastric bypass (LRYGB), laparoscopic adjustable gastric banding (LAGB), and the novel laparoscopic sleeve gastrectomy (LSG). The MEDLINE database (cutoff date September 2010), LILACS, and the Cochrane Library were searched using the key words "gastric bypass," "sleeve gastrectomy," and "gastric banding." Only studies that compared at least two of the laparoscopic procedures were included. Reviews and meta-analysis, editorial letters or comments, case reports, animal or in vitro studies, comparisons with medical treatment, comparisons with open (non-laparoscopic) procedures were excluded. Most studies indicated that LRYGB and LSG could be more effective achieving weight loss than LAGB. However, LAGB seems to be a safer procedure with frequent, but less severe, long-term complications. Although not uniformly reported, a resolution of obesity-related comorbidities was achieved with most bariatric procedures. The three procedures have acceptable efficacy and safety. We believe that patients should be informed in detail on the advantages and disadvantages of each available procedure, possibly in several interviews and always accompanied by a specialized interdisciplinary team, warranting long-term follow-up.

    Background: Sufentanil is widely used for patient-controlled intravenous analgesia (PCIA). Oxycodone has a powerful analgesic effect and mild side effects. We conducted this study to compare the efficacy of oxycodone and sufentanil for PCIA on postoperative pain after laparoscopic radical gastrectomy. Methodology: A total of fifty patients scheduled for laparoscopic radical gastrectomy were equally randomized to receive postoperative pain treatment with either oxycodone (Group O) or sufentanil (Group S) for 48 h postoperatively. PCIA was set on demand mode without loading dose or background infusion. Postoperative cumulative sufentanil or oxycodone consumption, pain intensity, sedation status, and side effects were assessed. Results: No significant differences were detected in visual analog scale score at rest and during coughing in the two groups at various time points after operation. Group S was associated with more doses delivered by PCIA than Group O. The overall satisfaction degree was higher in Group O. The incidences of side effects were comparable between the two groups. Conclusion: Oxycodone is a valuable alternative for PCIA in patients undergoing laparoscopic radical gastrectomy. PMID:27746551

    A 73-year-old male presented with jaundice and severe muscle weakness. He was diagnosed with distal cholangiocarcinoma and paraneoplastic necrotizing autoimmune myopathy (NAM). Treatment of NAM consisted of dexamethasone pulse therapy, prednisone, and single-dose intravenous immunoglobulin. The distal cholangiocarcinoma was resected through a total laparoscopic pancreatoduodenectomy. After hospital discharge, muscle strength initially increased postoperatively; however, pneumonia resulted in the deterioration of his general condition and death 5 months after the diagnosis of paraneoplastic NAM.

    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.

    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

    AIM: To report the incidence and potential risk factors of small-volume chylous ascites (SVCA) following laparoscopic radical gastrectomy (LAG). METHODS: A total of 1366 consecutive gastric cancer patients who underwent LAG from January 2008 to June 2011 were enrolled in this study. We analyzed the patients based on the presence or absence of SVCA. RESULTS: SVCA was detected in 57 (4.17%) patients, as determined by the small-volume drainage (range, 30-100 mL/24 h) of triglyceride-rich fluid. Both univariate and multivariate analyses revealed that the total number of resected lymph nodes (LNs), No. 8 or No. 9 LN metastasis and N stage were independent risk factors for SVCA following LAG (P < 0.05). Regarding hospital stay, there was a significant difference between the groups with and without SVCA (P < 0.001). The 3-year disease-free and overall survival rates of the patients with SVCA were 47.4% and 56.1%, respectively, which were similar to those of the patients without SVCA (P > 0.05). CONCLUSION: SVCA following LAG developed significantly more frequently in the patients with ≥ 32 harvested LNs, ≥ 3 metastatic LNs, or No. 8 or No. 9 LN metastasis. SVCA, which was successfully treated with conservative management, was associated with a prolonged hospital stay but was not associated with the prognosis. PMID:25741151

    Background. The amount of excess weight loss (%EWL) among obese patients after bariatric surgery varies greatly. However, reliable predictors have not been established yet. The present study evaluated the preoperative psychological burden, coping style, and motivation to lose weight as factors determining postoperative treatment success. Methods. The sample included 64 morbidly obese patients with a preoperative BMI of 51 ± 8 kg/m2 who had undergone laparoscopic sleeve gastrectomy (LSG). Well-established questionnaires were applied before surgery to assess the psychological burden in terms of “perceived stress” (PSQ-20), “depression” (PHQ-9), “anxiety” (GAD-7), and “mental impairment” (ISR) as well as coping style (Brief COPE) and motivation to lose weight. %EWL as an indicator for treatment success was assessed on average 20 months after surgery. Results. Based on the %EWL distribution, patients were classified into three %EWL groups: low (14–39%), moderate (40–59%), and high (60–115%). LSG patients with high %EWL reported significantly more “active coping” behavior prior to surgery than patients with moderate and low %EWL. Patients' preoperative psychological burden and motivation to lose weight were not associated with %EWL. Conclusion. An “active coping” style might be of predictive value for better weight loss outcomes in patients following LSG intervention. PMID:26649192

    The study was carried out on type 2 diabetic obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Patients underwent regular glycemic controls throughout 3 years and all patients were defined cured from diabetes according to conventional criteria defined as normalization of fasting glucose levels and glycated hemoglobin in absence of antidiabetic therapy. After 3 years of follow-up, Continuous Glucose Monitoring (CGM) was performed in each patient to better clarify the remission of diabetes. In this study, we found that the diabetes resolution after LSG occurred in 40% of patients; in the other 60%, even if they showed a normal fasting glycemia and A1c, patients spent a lot of time in hyperglycemia. During the oral glucose tolerance test (OGTT), we found that 2 h postload glucose determinations revealed overt diabetes only in a small group of patients and might be insufficient to exclude the diagnosis of diabetes in the other patients who spent a lot of time in hyperglycemia, even if they showed a normal glycemia (<140 mg/dL) at 120 minutes OGTT. These interesting data could help clinicians to better individualize patients in which diabetes is not resolved and who could need more attention in order to prevent chronic complications of diabetes.

    BACKGROUND: The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. RESULTS: Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. CONCLUSION: In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG. PMID:28281472

    Treatment options for morbidly obese patients with complications from large paraesophageal hernias (PEH) are limited. Simple repair of the PEH has a high recurrence rate and may be associated with poor gastric function. We compared a series of patients who underwent repair of large PEH plus gastrostomy tube gastropexy (PEH-GT) with PEH plus sleeve gastrectomy (PEH-SG). Retrospective review of patients undergoing PEH-SG and patients with PEH-GT was performed. We assessed symptoms of delayed gastric emptying and reflux postoperatively. In selected patients, gastric-emptying studies and upper gastrointestinal contrast studies were also obtained. All patients with large PEH were repaired laparoscopically with sac resection, primary crural closure using pledgeted sutures, and biologic patch onlay. SG for patients undergoing concomitant weight loss surgery (PEH-SG) was performed with linear endoscopic staplers and staple line reinforcement. Patients undergoing PEH repair alone had a gastrostomy tube gastropexy (PEH-GT). Patients had intraoperative endoscopic evaluation and postoperative contrast swallow studies. In a 12-month period, five patients underwent laparoscopic PEH-SG; two of five had previous antireflux surgery and one of five with a previous diagnosis of delayed gastric emptying. Postoperatively, two patients undergoing PEH-SG had readmission for dehydration and odynophagia. Six-month follow-up body mass index was 32 kg/m2 for the PEH-SG group with no hernia recurrence and complete resolution of gastroesophageal reflux disorder symptoms. Six patients underwent PEH-GT, one for acute incarceration and anemia and four with previous antireflux surgery. Follow up at 8 months demonstrated one recurrence, four of six had severe delayed gastric emptying and reflux, three of six had additional hospitalization for poor oral intake, and three of six underwent reoperation for delayed gastric emptying. There were no perforations, leaks, or deaths in either group. Combined

    Pancreatic hydatid cysts are fairly rare. The disease can be encountered concurrently with systemic involvement or as an isolated pancreatic involvement. We report the first case of spleen-preserving laparoscopic distal pancreatectomy for a pancreatic hydatid cyst. There was no complication or recurrence. A 55-year-old woman was admitted to our centre with epigastric and back pain. Upper abdominal magnetic resonance imaging revealed a solitary cystic lesion with septations at the pancreatic tail level measuring 24 mm × 18 mm, which was initially thought to be a pancreatic mucinous cystic neoplasia. She underwent laparoscopic spleen-preserving distal pancreatectomy and cholecystectomy. Her post-operative course was uneventful and histopathological examination revealed a hydatid cyst in the pancreatic tail. PMID:28281482

    Gastric cancer poses a significant public health problem, especially in the Far East, due to its high incidence in these areas. Surgical treatment and guidelines have been markedly different in the West, but nowadays this debate is apparently coming to an end. Laparoscopic surgery has been employed in the surgical treatment of gastric cancer for two decades now, but with controversies about the extent of resection and lymphadenectomy. Despite these difficulties, the apparent advantages of the laparoscopic approach helped its implementation in early stage and distal gastric cancer, with an increase on the uptake for distal gastrectomy for more advanced disease and total gastrectomy. Nevertheless, there is no conclusive evidence about the laparoscopic approach yet. In this review article we present and analyse the current status of laparoscopic surgery in the treatment of gastric cancer.

    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.

    Introduction Increasing incidence of obesity in Indian population has led to an exponential rise in the number of bariatric operations performed annually. Laparoscopic Sleeve Gastrectomy (LSG) has been proposed to cause rapid remission of Type 2 Diabetes Melitus (T2DM) and metabolic syndrome in a weight loss independent manner. Aim To evaluate the effects of LSG on metabolic syndrome and central obesity in morbidly and severely obese Indian adults. Material and Methods: Study was conducted on 91 morbidly obese [Body Mass Index (BMI)>40 kg/m2] and severely obese (BMI>35 kg/m2) individuals who were suffering from diabetes, hypertension or dyslipidemia. The patients were followed up for six months and the trends of glycaemic control, mean blood pressure, lipid profile, weight loss parameters and changes in parameters of central obesity were studied. Results Weight loss was significant at three months postsurgery and was sustained through six months. There was significant improvement in glycaemic control leading to reduction in need for oral hypoglycaemic agents or insulin in majority of them and even discontinuation of these medications in few patients. Hypertension and dyslipidemia also showed an improving trend through six months postsurgery. There was a significant impact on reduction of central obesity in these patients as marked by significant reduction in waist to hip ratio. Conclusion LSG produces sustainable weight loss with significant improvement in glycaemic status and control of metabolic syndrome in severe to morbidly obese patients. LSG is also efficacious in reducing central obesity in Indian population which is a major depressive ailment amongst obese individuals. PMID:28273998

    AIM: 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. METHODS: 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). RESULTS: 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). CONCLUSION: 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

    Objective Traditionally, peritoneal catheter is inserted with midline laparotomy incision in ventriculoperitoneal (V-P) shunt procedures. Complications of V-P shunt is not uncommon and have been reported to occur in 5-37% of cases. The aim of this study is to compare the clinical outcomes and the operation time between laparotomy and laparoscopic groups. Methods A total of 155 V-P shunt procedures were performed to treat hydrocephalic patients of various origins in our institute between June 2006 to January 2010; 95 of which were laparoscopically guided and 65 were not. We reviewed the operation time, surgery-related complications, and intraoperative and postoperative problems. Results In the laparoscopy group, the mean duration of the procedure (52 minutes) was significantly shorter (p < 0.001) than the laparotomy group (109 minutes). There were two cases of malfunctions and one incidence of diaphragm injury in the laparotomy group. In contrast, there were neither malfunction nor any internal organ injuries in the laparoscopy group (p = 0.034). There were total of two cases of infections from both groups (p = 0.7). Conclusion Laparoscopically guided insertions of distal shunt catheter is considered a fast and safe method in contrast to the laparotomy technique. This method allows the exact localization of the peritoneal catheter and a confirmation of its patency. PMID:21113359

    Wandering spleen is a condition in which an incomplete fusion of the splenic ligaments allows the spleen to move within the abdomen, predisposing it to splenic torsion along its vascular pedicle. Torsion of a wandering spleen is an uncommon occurrence, especially in children, and associated torsion of the distal pancreas is even more unusual, with only four cases having been reported in adults. Non-specific clinical presentation makes radiologic evaluation essential in order to obtain a diagnosis and to send the patient for early surgery before life-threatening complications arise. Here we present a rare case of torsion of wandering spleen together with volvulus of the distal pancreas in a 13-year-old girl. In this case, prompt radiological assessment allowed for an early diagnosis, and the patient was successfully treated with urgent laparoscopic derotation of both the spleen and the distal pancreas as well as mesh splenopexy. To the best of our knowledge, this procedure has never been described in a pediatric setting.

    Introduction Roux-en-Y gastric bypass (RYGB) is considered the gold standard bariatric procedure with documented safety and effectiveness. Laparoscopic sleeve gastrectomy (LSG) is a newer procedure being done with increasing frequency. Randomized comparisons of LSG and other bariatric procedures are limited. We present the results of the first prospective randomized trial comparing LSG and RYGB in the Polish population. Aim To assess the efficacy and safety of LSG versus RYGB in the treatment of morbid obesity and obesity-related comorbidities. Material and methods Seventy-two morbidly obese patients were randomized to RYGB (36 patients) or LSG (36 patients). Both groups were comparable regarding age, gender, body mass index (BMI) and comorbidities. The follow-up period was at least 12 months. Baseline and 6 and 12 month outcomes were analyzed including assessment of percent excess weight lost (%EWL), reduction in BMI, morbidity (minor, major, early and late complications), mortality, reoperations, comorbidities and nutritional deficiencies. Results There was no 30-day mortality and no significant difference in major complication rate (0% after RYGB and 8.3% after LSG, p > 0.05) or minor complication rate (16.6% after RYGB and 10.1% after LSG, p > 0.05). There were no early reoperations after RYGB and 2 after LSG (5.5%) (p > 0.05). Weight loss was significant after RYGB and LSG but there was no difference between both groups at 6 and 12 months of follow-up. At 12 months %EWL in RYGB and LSG groups reached 64.2% and 67.6% respectively (p > 0.05). There was no significant difference in the overall prevalence of comorbidities and nutritional deficiencies. Conclusions Both LSG and RYGB produce significant weight loss at 6 and 12 months after surgery. The procedures are equally effective with regard to %EWL, reduction in BMI and amelioration of comorbidities at 6 and 12 months of follow-up. Laparoscopic sleeve gastrectomy and RYGB are comparably safe techniques with no

    Epidermoid cysts presenting within an intrapancreatic accessory spleen are rare non-neoplastic cysts typically occurring in the pancreatic tail. This entity is difficult to diagnose given there are many types of pancreatic neoplastic cysts. We herein describe two cases of an epidermoid cyst within an intrapancreatic accessory spleen for which we performed a resection by laparoscopic distal pancreatectomy. Epidermoid cysts in an intrapancreatic accessory spleen should therefore be considered in the differential diagnosis of pancreatic tail cystic lesions. Laparoscopic distal pancreatectomy can be a useful, minimally invasive surgical approach for treating these cysts as well as for the treatment of benign or low-grade malignant tumors located in the pancreatic body or tail.

    Obesity increases the likelihood of diseases like type 2 diabetes (T2D), heart disease, and cancer, and is one of the most serious public health problems of this century. In contrast to ineffectual prevention strategies, lifestyle modifications, and pharmacological therapies, bariatric surgery is a very effective treatment for morbid obesity and also markedly improves associated comorbidities like T2D. However, weight loss and resolution of T2D after bariatric surgery is heterogeneous and specific to type of bariatric procedure performed. Conventional mechanisms like intestinal malabsorption and gastric restriction do not fully explain this, and potent changes in appetite and the enteroinsular axis, as a result of anatomical reorganization and altered hormonal, neuronal, and nutrient signaling, are the portended cause. Uniquely these signaling changes appear to override vigorous homeostatic defenses of stable body weight and compelling self-gratifying motivations to eat and to reverse defects in beta-cell function and insulin sensitivity. Here we review mechanisms of weight loss and T2D resolution after Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy bariatric surgery, two markedly different procedures with robust clinical outcomes.

    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.

    Laparoscopic Roux-en-Y gastric bypass (LRYGBP) reduces appetite and induces significant and sustainable weight loss. Circulating gut hormones changes engendered by LRYGBP are implicated in mediating these beneficial effects. Laparoscopic sleeve gastrectomy (LSG) is advocated as an alternative to LRYGBP, with comparable short-term weight loss and metabolic outcomes. LRYGBP and LSG are anatomically distinct procedures causing differential entero-endocrine cell nutrient exposure and thus potentially different gut hormone changes. Studies reporting the comparative effects of LRYGBP and LSG on appetite and circulating gut hormones are controversial, with no data to date on the effects of LSG on circulating peptide YY3-36 (PYY3-36) levels, the specific PYY anorectic isoform. In this study, we prospectively investigated appetite and gut hormone changes in response to LRYGBP and LSG in adiposity-matched non-diabetic patients. Anthropometric indices, leptin, fasted and nutrient-stimulated acyl-ghrelin, active glucagon-like peptide-1 (GLP-1), PYY3-36 levels and appetite were determined pre-operatively and at 6 and 12 weeks post-operatively in obese, non-diabetic females, with ten undergoing LRYGBP and eight adiposity-matched females undergoing LSG. LRYGBP and LSG comparably reduced adiposity. LSG decreased fasting and post-prandial plasma acyl-ghrelin compared to pre-surgery and to LRYGBP. Nutrient-stimulated PYY3-36 and active GLP-1 concentrations increased post-operatively in both groups. However, LRYGBP induced greater, more sustained PYY3-36 and active GLP-1 increments compared to LSG. LRYGBP suppressed fasting hunger compared to LSG. A similar increase in post-prandial fullness was observed post-surgery following both procedures. LRYGBP and LSG produced comparable enhanced satiety and weight loss. However, LSG and LRYGBP differentially altered gut hormone profiles.

    Objective: Laparoscopic sleeve gastrectomy (LSG) is performed almost as often in Europe as laparoscopic Roux-Y-Gastric Bypass (LRYGB). We present the 3-year interim results of the 5-year prospective, randomized trial comparing the 2 procedures (Swiss Multicentre Bypass Or Sleeve Study; SM-BOSS). Methods: Initially, 217 patients (LSG, n = 107; LRYGB, n = 110) were randomized to receive either LSG or LRYGB at 4 bariatric centers in Switzerland. Mean body mass index of all patients was 44 ± 11 kg/m2, mean age was 43 ± 5.3 years, and 72% of patients were female. Minimal follow-up was 3 years with a rate of 97%. Both groups were compared for weight loss, comorbidities, quality of life, and complications. Results: Excessive body mass index loss was similar between LSG and LRYGB at each time point (1 year: 72.3 ± 21.9% vs. 76.6 ± 20.9%, P = 0.139; 2 years: 74.7 ± 29.8% vs. 77.7 ± 30%, P = 0.513; 3 years: 70.9 ± 23.8% vs. 73.8 ± 23.3%, P = 0.316). At this interim 3-year time point, comorbidities were significantly reduced and comparable after both procedures except for gastro-esophageal reflux disease and dyslipidemia, which were more successfully treated by LRYGB. Quality of life increased significantly in both groups after 1, 2, and 3 years postsurgery. There was no statistically significant difference in number of complications treated by reoperation (LSG, n = 9; LRYGB, n = 16, P = 0.15) or number of complications treated conservatively. Conclusions: In this trial, LSG and LRYGB are equally efficient regarding weight loss, quality of life, and complications up to 3 years postsurgery. Improvement of comorbidities is similar except for gastro-esophageal reflux disease and dyslipidemia that appear to be more successfully treated by LRYGB. PMID:28170356

    BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed ‘standalone’ bariatric procedure in India. Staple line gastric leaks occur infrequently but cause significant and prolonged morbidity. The aim of this retrospective study was to analyse the management of patients with a gastric leak after LSG for morbid obesity at our institution. PATIENTS AND METHODS: From February 2008 to 2014, 650 patients with different degrees of morbid obesity underwent LSG. Among these, all those diagnosed with a gastric leak were included in the study. Patients referred to our institution with gastric leak after LSG were also included. The time of presentation, site of leak, investigations performed, treatment given and time of closure of all leaks were analysed. RESULTS: Among the 650 patients who underwent LSG, 3 (0.46%) developed a gastric leak. Two patients were referred after LSG was performed at another institution. The mean age was 45.60 ± 15.43 years. Mean body mass index (BMI) was 44.79 ± 5.35. Gastric leak was diagnosed 24 h to 7 months after surgery. One was early, two were intermediate and two were late leaks. Two were type I and three were type II gastric leaks. Endoscopic oesophageal stenting was used variably before or after re-surgery. Re-surgery was performed in all and included stapled fistula excision (re-sleeve), suture repair only or with conversion to roux-en-Y gastric bypass or fistula jujenostomy. There was no mortality. CONCLUSION: Leakage closure time may be shorter with intervention than expectant management. Sequence and choice of endoscopic oesophageal stenting and/or surgical re-intervention should be individualized according to clinical presentation. PMID:27251808

    Laparoscopy-assisted proximal gastrectomy (LAPG) with esophagogastrostomy using a novel "open-door" technique was introduced recently, with the aim of preventing gastroesophageal reflux. However, quantitate assessment of gastroesophageal reflux after this surgery has not been performed till date. The aims of the current study were to investigate the safety and feasibility of this operation and to elucidate the postoperative reflux status. Twenty consecutive patients (18 men) with (y)cStage I gastric cancer in the upper third of the stomach who underwent LAPG at Kitasato University Hospital from May 2015 through September 2016 were retrospectively reviewed. We performed 24-h impedance-pH monitoring 3 months after surgery for the first eight patients and analyzed the postoperative reflux status. Median operation time was 333 min, while median anastomotic time was 81 min. None of the 20 patients experienced anastomotic leakage while two patients experienced anastomotic stricture requiring endoscopic balloon dilatation. No patient experienced heartburn without antacid drugs. During the 24-h impedance-pH monitoring, all but one patient had normal gastroesophageal acid reflux with the acid percent time of <1.1% and reflux percent time of <1.4%. One patient with marginally abnormal postoperative gastroesophageal reflux had a normal DeMeester score of 3.0. Our results showed that esophagogastrostomy using the "open-door" technique is a safe and feasible procedure for LAPG. The degree of gastroesophageal reflux was acceptable using this technique. Randomized controlled trials with long-term follow-ups are required to confirm that this technique would be superior to the others.

  14. Risk factors for postoperative pancreatic fistula after laparoscopic distal pancreatectomy using stapler closure technique from one single surgeon

    2017-01-01

    Laparoscopic distal pancreatectomy (LDP) is a safe and reliable treatment for tumors in the body and tail of the pancreas. Postoperative pancreatic fistula (POPF) is a common complication of pancreatic surgery. Despite improvement in mortality, the rate of POPF still remains high and unsolved. To identify risk factors for POPF after laparoscopic distal pancreatectomy, clinicopathological variables on 120 patients who underwent LDP with stapler closure were retrospectively analyzed. Univariate and multivariate analyses were performed to identify risk factors for POPF. The rate of overall and clinically significant POPF was 30.8% and13.3%, respectively. Higher BMI (≥25kg/m2) (p-value = 0.025) and longer operative time (p-value = 0.021) were associated with overall POPF but not clinically significant POPF. Soft parenchymal texture was significantly associated with both overall (p-value = 0.012) and clinically significant POPF (p-value = 0.000). In multivariable analyses, parenchymal texture (OR, 2.933, P-value = 0.011) and operative time (OR, 1.008, P-value = 0.022) were risk factors for overall POPF. Parenchymal texture was an independent predictive factor for clinically significant POPF (OR, 7.400, P-value = 0.001). PMID:28235064

    Background Gastrointestinal mesenchymal or stromal tumors (GIST) are lesions originated on digestive tract walls, which are treated by surgical resection. Several laparoscopic techniques, from gastrectomies to segmental resections, have been used successfully. Aim Describe a single center experience on laparoscopic GIST resection. Method Charts of 15 operated patients were retrospectively reviewed. Thirteen had gastric lesions, of which ten were sub epithelial, ranging from 2-8 cm; and three were pure exofitic growing lesions. The remaining two patients had small bowel lesions. Surgical laparoscopic treatment consisted of two distal gastrectomies, 11 wedge gastric resections and two segmental enterectomies. Mechanical suture was used in the majority of patients except on six, which underwent resection and closure using manual absorbable sutures. There were no conversions to open technique. Results Mean operative time was 1h 29 min±92 (40-420 min). Average lenght of hospital stay was three days (2-6 days). There were no leaks, postoperative bleeding or need for reintervention. Mean postoperative follow-up was 38±17 months (6-60 months). Three patients underwent adjuvant Imatinib treatment, one for recurrence five months postoperatively and two for tumors with moderate risk for recurrence . Conclusion Laparoscopic GIST resection, not only for small lesions but also for tumors above 5 cm, is safe and acceptable technique. PMID:27120729

    Although a variety of techniques have been used to manage the distal ureter during laparoscopic radical nephroureterectomy (LNU), a consensus has not yet been established. Recently, some authors have used a single-port transvesical approach to excise the distal ureter and bladder cuff following LNU. The aim of the study was to present our initial experience in "en bloc" dissection of the distal ureter and bladder cuff during LNU, using a transvesical single-port approach (T-LESS) and standard laparoscopic instruments. From April to October 2012, 5 patients aged 45 to 73 years with upper urinary tract urothelial tumors were subjected to LNU/T-LESS. After a standard LNU was performed, a TriPort+(®) device was introduced into the bladder and the pneumovesicum was established. A bladder cuff with a distal ureter was dissected and put in the paravesical tissue. The bladder wall defect was closed with the V-loc(®) 3/0 suture. The LNU was then completed in the flank position. All procedures were completed successfully. No significant blood loss or complications were observed. The mean operative time was 250 min (range: 200-370) for a total procedure and 59 min (range: 42-80) for the T-LESS stage. The postoperative hospital stay was 5.2 days (range: 4-9). Pathologic examination revealed no positive margin in any of the cases. The LNU/T-LESS approach is an efficient and safe procedure. A well-visualized dissection of the distal ureter, closing the defect of the bladder, the use of standard laparoscopic instruments and a good cosmesis are advantages of the method.

    Background Supra-pancreatic lymph node dissection is important in patients undergoing laparoscopic gastrectomy (LG) for gastric cancer. A clear view of the supra-pancreatic area is necessary for precise dissection of supra-pancreatic lymph nodes without injury to the pancreas. This retrospective study assessed the efficacy of T-shaped gauze (TSG) in retracting the pancreas during supra-pancreatic lymph node dissection. Methods The study cohort consisted of 80 patients who underwent LG for gastric cancer. Of these, 44 patients underwent pancreatic retraction with TSG (TSG group) and 36 without TSG (non-TSG group). The efficacy of TSG for pancreatic retraction was evaluated by comparing all grade and Clavien-Dindo grade ≥ III postoperative pancreatic fistula (POPF) and the total number of dissected supra-pancreatic lymph nodes in the TSG and non-TSG groups. Results The rates of all grade (6.8% vs. 11%) and of Clavien-Dindo grade ≥ III (2.2% vs. 5.5%) POPF were lower in the TSG than in the non-TSG group. The total number of supra-pancreatic lymph nodes harvested by Dissection 1+ (D1+) lymph node dissection was significantly higher in TSG than in non-TSG patients (P = 0.0078). Conclusion TSG may be useful for safe and efficient performance of supra-pancreatic lymph node dissection. PMID:27708539

    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.

    Epidermoid cysts arising in an intrapancreatic accessory spleen are exceedingly rare, furthermore the natural course of them is hardly known. We report a case correctly diagnosed with epidermoid cyst in an intrapancreatic accessory spleen, followed by 1 year observation, finally underwent surgical treatment. The patient presented with diarrhea. Contrast-enhanced computed tomography (CT) revealed a pancreatic cyst 20 mm in diameter, surrounded by a solid component showing the same enhancement as the spleen, suggesting the presence of an epidermoid cyst in an intrapancreatic accessory spleen. One year later, back discomfort developed, and a CT scan revealed that the cyst had grown to 38 mm in diameter. To obtain a definitive diagnosis, we performed a laparoscopic spleen-preserving distal pancreatectomy. The histopathological diagnosis was compatible with an epidermoid cyst in an intrapancreatic accessory spleen, which is benign. The postoperative course was uneventful. This case demonstrates that an epidermoid cyst arising in an intrapancreatic accessory spleen can rapidly grow, even if it is benign. Laparoscopic spleen-preserving distal pancreatectomy can be a useful procedure, with the advantages of low invasiveness and organ preservation, for the treatment of benign or low-grade malignant tumors located in the pancreatic body or tail.

    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.

  2. 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

    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.

    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.

  6. Pylorus-Preserving Gastrectomy for Gastric Cancer

    2016-01-01

    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.

    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

    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. PMID:26937322

    2014-01-01

    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.

    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

    This study was designed to evaluate the efficacy and safety of computed tomography (CT)-guided drainage in treating infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity. From January 2007 to June 2009, 21 patients (9 men and 12 women; mean age, 39.2 (range, 26-52) years) with infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity underwent image-guided percutaneous drainage. All procedures were performed using CT guidance and 8- to 12-Fr pigtail drainage catheters. Immediate technical success was achieved in all 21 infected collections. In 18 of 21 collections, we obtained progressive shrinkage of the collection with consequent clinical success (success rate 86%). In three cases, the abdominal fluid collection was not resolved, and the patients were reoperated. Among the 18 patients who avoided surgery, 2 needed replacement of the catheter due to obstruction. No major complications occurred during the procedure. The results of our study support that CT-guided percutaneous drainage is an effective and safe method to treat infected abdominal fluid collections due to gastric leak in patients who had previously underwent laparoscopic sleeve gastrectomy for morbid obesity. It may be considered both as a preparatory step for surgery and a valuable alternative to open surgery. Failure of the procedure does not, however, preclude a subsequent surgical operation.

    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

    The present study assessed preoperative splenic artery embolization using spherical embolic material, super absorbent polymer microspheres (SAP-MS), before laparoscopic or laparoscopically assisted splenectomy. Distal splenic artery embolization using 250 to 400 microm SAP-MS was performed in nine cases with ITP and in seven cases with the other diseases with splenomegaly. Laparoscopic or laparoscopically assisted splenectomies, including a hand-assisted procedure and the procedure involving left upper minilaparotomy, were done 2 to 4 hours after embolization. Conversion to traditional laparotomy was not required in any of the 16 cases, while conversion to 12-cm laparotomy was required in one case with massive splenomegaly. Mean operating time was 161 minutes, and mean intraoperative blood loss was 290 mL. No major postoperative complications were identified, and only one patient reported postembolic pain before surgery. Preoperative splenic artery embolization using painless embolic material, SAP-MS, would be effective for easy and safe laparoscopic or laparoscopically assisted splenectomy.

    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

  20. Carbon dioxide pneumothorax occurring during laparoscopy-assisted gastrectomy due to a congenital diaphragmatic defect: a case report

    PubMed Central

    Park, Hye-Jin

    2016-01-01

    During laparoscopic surgery, carbon dioxide (CO2) pneumothorax can develop due to a congenital defect in the diaphragm. We present a case of a spontaneous massive left-sided pneumothorax that occurred during laparoscopy-assisted gastrectomy, because of an escape of intraperitoneal CO2 gas, under pressure, into the pleural cavity through a congenital defect in the esophageal hiatus of the left diaphragm. This was confirmed on intraoperative chest radiography and laparoscopic inspection. This CO2 pneumothorax caused tolerable hemodynamic and respiratory consequences, and was rapidly reversible after release of the pneumoperitoneum. Thus, a conservative approach was adopted, and the remainder of the surgery was completed, laparoscopically. Due to the high solubility of CO2 gas and the extra-pulmonary mechanism, CO2 pneumothorax with otherwise hemodynamically stable conditions can be managed by conservative modalities, avoiding unnecessary chest tube insertion or conversion to an open procedure.

    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.

    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.

    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.

    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

    Background and Objectives: The advantages of laparoscopy over open surgery are well established. Laparoscopic resection for gastric cancer is safe and results in equivalent oncologic outcomes when compared with open resection. The purpose of this study was to assess the use of laparoscopy to treat gastric cancer and the associated outcomes. Methods: The American College of Surgeons National Surgical Quality Improvement Project (NSQIP) dataset was queried for patients with gastric cancer (ICD-9 Code 151.0–151.9) from January 2005 through December 2012. Logistic regression was used to evaluate the 30-day morbidity and mortality of open gastrectomy (CPT code 43620-2, 43631-4) versus that of the laparoscopic procedure on the stomach (CPT code 43650), while adjusting for preoperative risk factors. Results: A total of 4116 patients with gastric cancer were identified and divided by surgical approach into 2 groups: open gastrectomy (n = 3725; 90.5%) and laparoscopic procedure on the stomach (n = 391; 9.5%). After adjustment for preoperative risk factors, complications were significantly fewer in laparoscopic versus open gastric resection (odds ratio [OR] 0.61, 95% confidence interval [CI] = 0.45–0.82; P = .001). After adjusting for preoperative risk factors, there was no statistically significant difference in mortality with laparoscopic compared to open gastric resection (OR 0.74; 95% CI = 0.32–1.72; P = .481). Conclusions: Laparoscopy is underused in the treatment of gastric cancer. Given that laparoscopic gastric resection has a lower morbidity in comparison to open resection, steps should be made toward advancing the use of laparoscopy for gastric cancer. PMID:26941544

    China alone accounts for nearly 42% of all new gastric cancer cases worldwide, and gastric cancer is the third leading cause of cancer deaths in China nowadays. Without mass screening programs, unfortunately over 80% of all Chinese patients have been diagnosed as advanced diseases. As in other Asian countries, especially Japan and Korea, laparoscopic gastrectomy for the treatment of gastric cancer has gained increasingly popularity in China during the past decade. Whether laparoscopic surgery can be safely and effectively performed in the treatment of gastric cancer remains controversial, particularly with regard to curative intent in advanced diseases. Given the high incidence of these cancers, and their advanced stage at diagnosis, China has a significant interest in determining the safety and effectiveness of laparoscopic gastrectomy. A well-designed randomized controlled trial (RCT) is considered the only feasible way to provide conclusive evidence. To date, China has not played a significant role in terms of conducting RCT concerning laparoscopic surgery for gastric cancer. However, an effort has been made by the Chinese researchers, with the great help from our colleagues in neighboring countries such as Korea and Japan, through the establishment of the Chinese Laparoscopic Gastrointestinal Surgery Study Group. In this review, we present the current status of RCT for laparoscopic gastric surgery for gastric cancer in China, including published and ongoing registered RCT.

    Ventriculoperitoneal (VP) shunts are the most common treatment modality for hydrocephalus. Distal catheter malfunction represents a surgical emergency and a significant cause of procedural morbidity. We report the case of a patient with acute abdominal pain following VP shunt insertion. On examination she had a tender, irreducible bulge at the abdominal laparotomy site. Exploratory laparoscopy of the abdomen yielded no abdominal wall abnormalities. At the same time, the distal catheter was noted to be absent. The abdominal bulge was incised along the laparotomy scar and clear cerebrospinal fluid was encountered. The incision was explored and the distal catheter was coiled and knotted within the preperitoneal space. The catheter was laparoscopically returned to the peritoneal cavity. This case exemplifies the utility of laparoscopy for VP shunt revision and we present a review of laparoscopic shunt revision.

    This paper presents a method for generating branching pattern reports of abdominal blood vessels for laparoscopic gastrectomy. In gastrectomy, it is very important to understand branching structure of abdominal arteries and veins, which feed and drain specific abdominal organs including the stomach, the liver and the pancreas. In the real clinical stage, a surgeon creates a diagnostic report of the patient anatomy. This report summarizes the branching patterns of the blood vessels related to the stomach. The surgeon decides actual operative procedure. This paper shows an automated method to generate a branching pattern report for abdominal blood vessels based on automated anatomical labeling. The report contains 3D rendering showing important blood vessels and descriptions of branching patterns of each vessel. We have applied this method for fifty cases of 3D abdominal CT scans and confirmed the proposed method can automatically generate branching pattern reports of abdominal arteries.

    Qualified radical gastrectomy with lymph node dissection is very important to the prognosis of patients with gastric cancer. Now D2 lymph node dissection is standard procedure for gastric cancer surgery, and spleen hilar lymph node dissection is mandatory for gastric cancer in upper body. Because the anatomy of vessels in this area is very complicated, D2 lymph node dissection is technical challenging not only for open gastrectomy but also for laparoscopic one. Adapting a new technique is important to all surgeons, but we surgeons should always consider a patient’s safety as the most important factor during surgery and that efforts should be based on scientific rationale with oncologic principles. I hope that the recent report by Huang et al. about laparoscopic spleen preserving hilar lymph node dissection would be helpful to young surgeons who will perform laparoscpic total gastrectomy for gastric cancer.

    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

    Laparoscopic gastrectomy has not become a common procedure for gastric cancer due to the difficulties of performing D2 lymphadenectomy and reconstruction of digestive tract by the conventional laparoscopic instruments. The da Vinci system provides 3D visualization, enhanced magnification, and seven degrees of freedom of the instruments to suture and knot in the narrow surgical space, so it can perform totally robotic gastrectomy with D2 lymphadenectomy and robot-sewing anastomosis for reconstruction. Application of robotic system can expand the indications of minimally invasive surgery in treatment of gastric cancer. Combination fast-track surgery to optimize the perioperative management with the technique of minimally invasive surgery can enhance the recovery of surgical gastric cancer patients.

    2005-01-01

    Distal pancreatectomy with en-bloc splenectomy has been considered the standard technique for management of benign and malignant pancreatic disorders. However, splenic preservation has recently been advocated. The aim of this study was to review the experiences of distal pancreatectomy using the open or the laparoscopic approach and to critically discuss the need to perform splenectomy. Original articles published in the English literature of peer-reviewed medical journals were selected for detailed analysis. In patients with malignant neoplasms in the body-tail of the pancreas, splenectomy has a negative influence on long-term survival after resection. The incidence of diabetes after spleen-preserving distal pancreatectomy for chronic pancreatitis is less than after en-bloc splenectomy. Spleen salvage eliminates the risk of overwhelming infections. Laparoscopic spleen-preserving distal pancreatectomy is feasible and safe. Laparoscopic spleen-preserving distal pancreatectomy may be preferable for the advantages of a minimally invasive approach.

    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.

    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

    This study compared robotic (RR) and laparoscopic resection (LR) for primary gastrointestinal stromal tumors (GISTs) of the stomach >5 cm. Twelve consecutive patients who underwent RR from 2012 to 2015 were matched for tumor size and location with 24 patients who underwent LR from 2000 to 2012. The median tumor size was 7.1 cm (range, 5.5 to 11.5). GISTs were resected by wedge resection (91.7%) or distal gastrectomy. The median RR operative time was longer than that of LR (162.5 vs. 130 min, respectively; P=0.004). Only 1 LR patient required conversion. The time to flatus and hospital stay were similar between groups. Overall, 3 patients developed minor postoperative complications that were medically treated. Mortality was nil. All resections were R0. No difference was observed in the incidence of recurrence. RR was significantly more expensive (+21.6%) than LR. RR appears to be safe and feasible for GISTs>5 cm, but is associated with longer operative times and greater costs.

    2014-01-01

    Background and Objectives: Single-incision laparoscopic surgery is gaining popularity among minimally invasive surgeons and is now being applied to a broad number of surgical procedures. Although this technique uses only 1 port, the diameter of the incision is larger than in standard laparoscopic surgery. The long-term incidence of port-site hernias after single-incision laparoscopic surgery has yet to be determined. Methods: All patients who underwent a single-incision laparoscopic surgical procedure from May 2008 through May 2009 were included in the study. Single-incision laparoscopic surgical operations were performed either by a multiport technique or with a 3-trocar single-incision laparoscopic surgery port. The patients were seen at 30 to 36 months' follow-up, at which time they were examined for any evidence of port-site incisional hernia. Patients found to have hernias on clinical examination underwent repairs with mesh. Results: A total of 211 patients met the criteria for inclusion in the study. The types of operations included were cholecystectomy, appendectomy, sleeve gastrectomy, gastric banding, Nissen fundoplication, colectomy, and gastrojejunostomy. We found a port-site hernia rate of 2.9% at 30 to 36 months' follow-up. Conclusion: Port-site incisional hernia after single-incision laparoscopic surgical procedures remains a major setback for patients. The true incidence remains largely unknown because most patients are asymptomatic and therefore do not seek surgical aid. PMID:24960483

    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.

    Distal pancreatectomy is the standard procedure for tumors located in the body and tail of the pancreas. In the last three decades, significant progress has been made with regard to technical aspects as well as perioperative care so that excellent mortality and morbidity rates can be achieved. Recently, there is growing evidence that distal pancreatectomy may be performed laparoscopically in selected patients, offering the advantages of minimally invasive surgery. Unfortunately, the oncologic outcomes for pancreatic adenocarcinoma remain poor, in part due to the late stage of presentation in most patients. We review the history of distal pancreatectomy, discuss current indications for performing this procedure, compare operative techniques in performing distal pancreatectomy, and review both the early complications seen in patients who have undergone a distal pancreatectomy and the long-term metabolic and oncologic outcomes of these patients.

    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

    Although mesenterioaxial gastric volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal hernia, volvulus, and gastroesophageal reflux.

    A common complication after bariatric surgery is hair loss, which is related to rapid weight reduction, but zinc, iron, and other micronutrient deficiencies can also be involved. Little is studied after laparoscopic sleeve gastrectomy (LSG). A prospective observational study was performed of 42 morbidly obese females undergoing LSG. Incidence of hair loss was monitored. Micronutrients were investigated preoperatively and three, six, and 12 months after surgery. Sixteen patients (41%) reported hair loss in the postoperative course. A significant association was observed between hair loss and zinc levels (P = 0.021) but mean zinc levels were within the normal range in patients reporting hair loss. Only three patients (7.7%) presented low zinc levels, all of them reporting hair loss. There was also a significant association between iron levels and alopecia (P = 0.017), but mean values of the patients with hair loss were within normal range. Only four patients (10.2%) presented low iron levels, all of them presenting hair loss. A variable consisting of the addition of zinc + iron showed a significant association with hair loss (P = 0.013). A cutoff point was established in 115 (odds ratio, 4; P = 0.006). All the patients but two reporting hair loss presented addition levels under 115. This variable showed sensibility 88 per cent, specificity 84 per cent, positive predictive value 79 per cent, and negative predictive value 91 per cent to predict hair loss. Hair loss is a frequent condition after sleeve gastrectomy. In most cases, iron and zinc levels are within the normal range. The variable addition (zinc + iron) is a good predictor of hair loss. Patients with addition levels below 115 are fourfold more susceptible to present hair loss. In these cases, zinc supplements achieve the stop of hair loss in most cases.

    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.

    Laparoscopy-assisted gastrectomy (LAG) has gained international acceptance for the treatment of early gastric cancer (EGC). However, the use of laparoscopic surgery in the management of advanced gastric cancer (AGC) has not attained widespread acceptance. This retrospective large-scale patient study in a single center for minimally invasive surgery assessed the feasibility and safety of LAG for T2 and T3 stage AGC. A total of 628 patients underwent LAG and 579 patients underwent open gastrectomy (OG) from Jan 2004 to Dec 2011. All cases underwent radical lymph node (LN) dissection from D1 to D2+. This study compared short- and long-term results between the 2 groups after stratifying by pTNM stages, including the mean operation time, volume of blood loss, number of harvested LNs, average days of postoperative hospital stay, mean gastrointestinal function recovery time, intra- and post-operative complications, recurrence rate, recurrence site, and 5-year survival curve. Thirty-five patients (5.57%) converted to open procedures in the LAG group. There were no significant differences in retrieved LN number (30.4 ± 13.4 vs 28.1 ± 17.2, P = 0.43), proximal resection margin (PRM) (6.15 ± 1.63 vs 6.09 ± 1.91, P = 0.56), or distal resection margin (DRM) (5.46 ± 1.74 vs 5.40 ± 1.95, P = 0.57) between the LAG and OG groups, respectively. The mean volume of blood loss (154.5 ± 102.6 vs 311.2 ± 118.9 mL, P < 0.001), mean postoperative hospital stay (7.6 ± 2.5 vs 10.7 ± 3.6 days, P < 0.001), mean time for gastrointestinal function recovery (3.3 ± 1.4 vs 3.9 ± 1.5 days, P < 0.001), and postoperative complications rate (6.4% vs 10.5%, P = 0.01) were clearly lower in the LAG group compared to the OG group. However, the recurrence pattern and site were not different between the 2 groups, even they were stratified by the TNM stage. The 5-year overall survival (OS) rates were 85.38%, 79.70%, 57

    Introduction The effectiveness of sleeve gastrectomy has been confirmed in many studies. The impact of individual factors on the parameters of weight loss is still not clear. Aim To identify important factors affecting the parameters of weight loss after sleeve gastrectomy. Material and methods The impact of prognostic factors and postoperative care components on body mass index (BMI) and percentage excess weight loss (%EWL) was assessed in a group of 100 consecutive patients who underwent laparoscopic sleeve gastrectomy. Results The baseline BMI and body mass in patients with BMI < 30 kg/m2 and BMI ≥ 30 kg/m2 12 months after surgery were, respectively, 39.7 ±3.2 vs. 45.9 ±4.6 kg/m2, p < 0.0001, and 114.4 ±16.8 vs. 130.3 ±18.5 kg, p < 0.0001. In the group with EWL < 50%, the average age was 47.1 ±7.7 vs. 40.6 ±10.8 in the group with EWL ≥ 50%, p = 0.0025. In the group of patients with preoperative weight loss, %EWL was 61.4 ±17.2 vs. 53.3 ±19.3% in the group with no weight loss, p = 0.0496. Body mass index of the patients who started physical activities was 30.6 ±4.2 kg/m2 vs. 34.0 ±5.6 kg/m2 in the patients with no physical activity, p = 0.0013, and %EWL was 63.4 ±14.6 vs. 47.0 ±19.9%, p < 0.0001, respectively. In the case of patients regularly consulted by a dietician BMI was 30.6 ±4.2 kg/m2 vs. 35.1 ±5.5 kg/m2 in the group without systematic consultations, p < 0.0001, and %EWL was 63.1 ±15.1% vs. 42.3 ±18.2%, p < 0.0001. Conclusions Lower baseline body weight parameters, younger age, preoperative weight loss, starting systematic physical activities and constant care of a dietician were conducive to achieving better results of surgery, as assessed on the basis of changes in BMI and %EWL.

    Objective. 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. Methods. 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. Results. 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. Conclusion. The change of dominant microorganisms in intestinal flora might play an important role in the glucose metabolism. PMID:25165722

    Introduction. Aim of the study was trying to draw a final flow chart for the management of gastric leaks after laparoscopic sleeve gastrectomy, based on the review of our cases over 10 years' experience. Material and Methods. We retrospectively reviewed all patients who underwent LSG as a primary operation at the Bariatric Unit of Tor Vergata University Hospital in Rome from 2007 to 2015. Results. Patients included in the study were 418. There were 6 staple line leaks (1.44%). All patients with diagnosis of a leak were initially discharged home in good clinical conditions and then returned to A&E because of the complication. The mean interval between surgery and readmission for leak was 13,4 days (range 6–34 days, SD ± 11.85). We recorded one death (16.67%) due to sepsis. The remaining five cases were successfully treated with a mean healing time of the gastric leak of 55,5 days (range 26–83 days; SD ± 25.44). Conclusion. Choosing the proper treatment depends on clinical stability and on the presence or not of collected abscess. Our treatment protocol showed being associated with low complication rate and minor discomfort to the patients, reducing the need for more invasive procedures. PMID:28261497

    1998-01-01

    A retrospective study was carried in 1500 patients submitted to elective laparoscopic cholecystectomy to ascertain its feasibility in patients with previous abdominal surgery. In 411 patients (27.4%) previous infraumbilical intraperitoneal surgery had been performed, and 106 of them (7.06%) had 2 or more operations. Twenty five patients (1.66%) had previous supraumbilical intraperitoneal operations (colonic resection, hydatid liver cysts, gastrectomies, etc.) One of them had been operated 3 times. In this group of 25 patients the first trocar and pneumoperitoneum were performed by open laparoscopy. In 2 patients a Marlex mesh was present from previous surgery for supraumbilical hernias. Previous infraumbilical intraperitoneal surgery did not interfere with laparoscopic cholecystectomy, even in patients with several operations. There was no morbidity from Verres needle or trocars. In the 25 patients with supraumbilical intraperitoneal operations, laparoscopic cholecystectomy was completed in 22. In 3, adhesions prevented the visualization of the gallbladder and these patients were converted to an open procedure. In the 2 patients Marlex mesh prevented laparoscopic cholecystectomy because of adhesions to abdominal organs. We conclude that in most instances previous abdominal operations are no contraindication to laparoscopic cholecystectomy. PMID:9515231

    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

    2016-01-01

    Background Central pancreatectomy (CP) is preferred to distal pancreatectomy (DP) for the excision of benign tumours at the neck or body of the pancreas, in order to preserve pancreatic function and the spleen. However, the pancreaticoenterostomy is technically difficult to perform laparoscopically and the postoperative pancreatic fistula (POPF) rate is high. Methods A novel laparoscopic reconstruction of the pancreatic stump during CP is described, the laparoscopic long sleeve pancreaticogastrostomy (LPG). Results Two males and two females with a median age of 49 years had a laparoscopic CP with LPG. After a median follow-up of 27.5 months, there was no mortality. One patient had a grade A POPF, managed conservatively. Conclusions The LPG is a safe and technically less demanding method to reconstruct pancreatic drainage laparoscopically. PMID:27275466

    OBJECTIVE: The authors laparoscopic approach for a Nissen fundoplication is presented. SUMMARY BACKGROUND DATA: The technique has been undertaken in 155 patients over 29 months, with 137 patients having been observed for more than 3 months. METHODS: Three hundred sixty degree fundoplication was undertaken using three or four sutures to secure the wrap. Short gastric vessels were not divided, and the anterior wall of the stomach was used to construct the wrap around the esophagus with a large bougie in position. RESULTS: The operation was not completed laparoscopically in 19 patients because a satisfactory wrap could not be achieved. Ten patients undergoing laparoscopic fundoplication underwent a subsequent operation related to the laparoscopic procedure within 6 months, and there was one postoperative death. Seven other patients were readmitted to the hospital several days subsequent to their discharge, four because of pulmonary emboli. Of 137 patients who have been observed for more than 3 months, 133 patients are well and currently are free from reflux symptoms. CONCLUSIONS: In uncomplicated cases, laparoscopic fundoplication has similar advantages to laparoscopic cholecystectomy. In spite of the fact that it has not yet achieved the overall usefulness of open fundoplication, it seems likely that laparoscopic fundoplication will be used increasingly in the treatment of patients with gastroesophageal reflux disease.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    Prof Dr Med Erich Mühe of Böblingen, Germany, performed the first laparoscopic cholecystectomy on September 12, 1985. The German Surgical Society rejected Mühe in 1986 after he reported that he had performed the first laparoscopic cholecystectomy, yet in 1992 he received their highest award, the German Surgical Society Anniversary Award. In 1990 in Atlanta, at the Society of American Gastrointestinal Surgeons (SAGES) Convention, Perissat, Berci, Cuschieri, Dubois, and Mouret were recognized by SAGES for performing early laparoscopic cholecystectomies, but Mühe was not. However, in 1999 he was recognized by SAGES for having performed the first laparoscopic cholecystectomy-SAGES invited Mühe to present the Storz Lecture. In Mühe's presentation, titled "The First Laparoscopic Cholecystectomy," which he gave in March 1999 in San Antonio, Texas, he described the first procedure. Finally, Mühe had received the worldwide acclaim that he deserved for his pioneering work. One purpose of this article is to trace the development of the basic instruments used in laparoscopic cholecystectomy. The other purpose is to give Mühe the recognition he deserves for being the developer of the laparoscopic cholecystectomy procedure.

    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.

    Surgical treatment of distal rectal cancer has long been based only on abdominoperineal excision, resulting in a permanent stoma and not always offering a definitive local control. Sphincter saving surgery has emerged in the last 20 years and can be offered also to patients with low lying tumours, provided that the external sphincter is not involved by the disease. An intersphincteric resection (ISR) is based on the resection of the rectum with a distal dissection proceeding into the space between the internal and the external anal sphincter. Originally described as an open procedure, it has also been developed with the laparoscopic approach, and also this technically demanding procedure is inscribed among those offered to the patient by a minimally invasive surgery. Indications have to be strict and patient selection is crucial to obtain both oncological and functional optimal results. The level of distal dissection and the extent of internal sphincter resected are chosen according to the distal margin of the tumour and is based on MRI findings: accurate imaging is therefore mandatory to better define the surgical approach. We here present our actual indications for ISR, results in terms of operative time, median hospital stay for ISR in our experience and review the updated literature.

    2016-01-01

    Following bariatric surgery, a proportion of patients have been observed to experience reflux, dysphagia, and/or odynophagia. The etiology of this constellation of symptoms has not been systematically studied to date. This case describes a 36-year-old female with severe esophageal dysmotility following LSG. Many treatments had been used over a course of 3 years, and while calcium channel blockers reversed the esophageal dysmotility seen on manometry, significant symptoms of dysphagia persisted. Subsequently, the patient underwent a gastric bypass, which seemed to partially relieve her symptoms. Her dysphagia was no longer considered to be associated with a structural cause but attributed to a “sleeve dysmotility syndrome.” Considering the difficulties with managing sleeve dysmotility syndrome, it is reasonable to consider the need for preoperative testing. The question is whether motility studies should be required for all patients planning to undergo a LSG to rule out preexisting esophageal dysmotility and whether conversion to gastric bypass is the preferred method for managing esophageal dysmotility after LSG.

    Objective Intracorporeal reconstruction of the digestive tract is technically challenging. The V-Loc 180 wound closure device (Covidien) is a self-anchoring unidirectional barbed suture that obviates the need for knot tying. The aim of this prospective cohort study was to investigate the use of the novel suture in gastrointestinal enterotomy closure. Methods The subjects comprised patients with malignant disease who were scheduled to undergo laparoscopic gastrectomy with curative intent. The barbed suture was used to close the entry hole for the linear stapler during intracorporeal reconstruction following laparoscopic gastric resection. The primary endpoint was the proportion of patients who developed anastomotic leakage at the site where the barbed suture was applied. Results Between July 2012 and March 2015, 242 patients were enrolled. Of 362 anastomoses, the enterotomy hole at 256 sites was closed using the barbed suture. These 256 sites consisted of 95 gastroduodenostomies, 25 gastrogastrostomies, 13 gastrojejunostomies, 90 jejunojejunostomies, 17 esophagojejunostomies and 16 primary closures of the stomach following local gastric resection. There were no anastomosis-related complications, conversion to usual sutures, mechanical closure of the entry hole and reoperation due to adhesive obstructions or mortality over a median follow-up period of 17.8 months. Conclusions The use of the unidirectional barbed absorbable suture for gastrointestinal closure is safe and effective in laparoscopic gastrectomy. PMID:26819279

    1984-03-01

    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.

    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.

    2002-01-01

    The main controversy of colon-rectal laparoscopic surgery comes from its use as a cancer treatment. Two points deserve special attention: the incidence of portsite tumor implantation and the possibility of performing radical cancer surgery, such as total mesorectum excision. Once these points are addressed, the laparoscopic approach will be used routinely to treat rectal cancer. To clarify these points, 32 patients with cancer of the lower rectum participated in a special protocol that included preoperative radiotherapy and laparoscopic total mesorectum excision. All data were recorded. At the same time, all data recorded from the experience of a multicenter laparoscopic group (Brazilian Colorectal Laparoscopic Surgeons – 130 patients with tumor of the lower rectum) were analyzed and compared with the data provided by our patients. Analysis of the results suggests that a laparoscopic approach allows the same effective resection as that of conventional surgery and that preoperative irradiation does not influence the incidence of intraoperative complications. The extent of lymph nodal excision is similar to that obtained with open surgery, with an average of 12.3 lymph nodes dissected per specimen. The rate of local recurrence was 3.12%. No port site implantation of tumor was noted in this series of patients with cancer of the lower rectum. PMID:12113422

    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.

    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.

    Laparoendoscopic technology has revolutionized the practice of surgery; however, surgeons have not widely accepted laparoscopic techniques for pancreatic surgeries due to the complexity of the operation. Natural orifice transluminal endoscopic surgery (NOTES) offers a great new potential for pancreatic procedures, with early data showing benefits of reduced visible scarring and the potential for decreased wound infections, hernias, pain, and postoperative complications. However, there are significant limitations to the currently used flexible endoscopy tools, including a diminished visual field, spatial orientation and tissue manipulation issues, and 2-dimensional visual feedback. We have adopted a novel snake-like robot, the minimally invasive cardiac surgery (MICS) robot, which addresses these issues. In the current pilot study, the MICS robot was evaluated for transrectal distal pancreas exploration and resection in 2 nonsurvival porcine models. Abdominal navigation and accessing the pancreas was investigated in the first pig, and based on its success, pancreas resection was studied in pig 2. The MICS robot was successful in accessing and visualizing the right upper, left upper, and left lower quadrants of the abdomen in pig 1 and was able to perform a successful complex NOTES procedure with distal pancreas resection in pig 2, with only minimal laparoscopic retraction assistance. In conclusion, preliminary results showing the MICS robot in natural orifice distal pancreatectomy are positive. Enhancements to optics and instrumentation will help further increase the usability in pancreatic interventions. Future indications may include transgastric NOTES approaches, endoluminal procedures, and single-port applications.

    Intraarterial thrombolysis is usually contraindicated after abdominal surgery because of the risk of bleeding. However, it is a highly effective treatment for embolic acute limb ischemia, particularly for clearing the distal vessels. We report a case in which intraarterial thrombolysis was safely used 4 days after laparoscopic cholecystectomy in a patient with an acutely ischemic leg due to embolus.

    No randomized clinical trials (RCTs) have yet evaluated the bariatric surgery's efficacy and safety in patients newly diagnosed with type 2 diabetes mellitus (T2DM). The aim of this multicenter RCT is to compare bariatric surgery, particularly laparoscopic sleeve gastrectomy (LSG), with conventional medical therapy (CMT) in obese patients (body mass index between 30 and 42 kg/m(2)) newly diagnosed with T2DM and without any diabetes-related complications at any stage. A total of 100 eligible patients will be randomized at a 1:1 ratio to undergo one of the two planned treatments and will be followed for at least 6 years after randomization. The main objective of the ESINODOP trial is to investigate the efficacy of LSG compared with CMT alone in inducing and maintaining a remission of T2DM (defined as HbA1c levels ≤6.0 %, without active pharmacologic therapy after 1 year). The remission of T2DM will also be evaluated with the criteria provided by the American Diabetes Association (ADA), and the additional parameters such as adverse event rates, micro- and macrovascular complications, weight loss, gastrointestinal hormones, and quality of life will be compared. The study started on September 2015 and the planned recruitment period is 3 years. Patient recruitment and follow-up take place in the two diabetology and nutrition centers participating in the study, which are performed on a national basis. The ESINODOP trial is designed with the intent of comparing the efficacy of CMT alone to that of CMT in conjunction with LSG performed at the time of diabetes diagnosis in mildly obese diabetic patients. Currently, patients with these characteristics are not eligible for bariatric/metabolic surgery.

    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.

    The aim of this study was to elucidate the consequences of small bowel bacterial overgrowth (SBBO) after total gastrectomy. A total of 127 patients, evaluated for SBBO with a radiographically controlled H2-breath test (subgroup I, without SBBO, n = 80; subgroup II, with SBBO, n = 47) after potentially curative total gastrectomy for gastric malignancy, were uniformly evaluated. Mean time since operation was significantly shorter in subgroup II than in subgroup I [370 days, confidence interval (CI) 96-645 days, vs. 687 days, CI 397-976 days; P < 0.01]. Controlling for this difference, there were no other significant differences in symptoms and signs between the subgroups except for the medico-social functioning measured with the Edinburgh Rehabilitation Status Scale (ERSS). The mean ERSS showed significantly better medicosocial functioning in subgroup I than in subgroup II [3.7 (CI 2.2-5.2) vs. 5.1 (CI 3.0-7.0); P < 0.05]. After total gastrectomy, patients without SBBO did not differ significantly from patients with SBBO in most parameters. Medicosocial functioning was significantly poorer in the latter.

    Abstract Background Laparoscopic repair of congenital duodenal obstruction has become popularized over the past decade. Comparative data on outcomes, however, are sparse. We hypothesized that laparoscopic repair of congenital duodenal obstruction could be performed with similar outcomes to traditional open repair. Patients and Methods Medical records for all cases of congenital duodenal obstruction from 2005 to 2011 at three academic teaching hospitals were retrospectively reviewed. Patients were excluded from the analysis if they had confounding surgical diseases, did not have duodenoduodenostomy during the first hospital admission, had the repair performed before transfer from a referring hospital, or weighed less than 1.7 kg at the time of surgery. Analysis was performed as intention to treat, with laparoscopic converted to open cases included in the laparoscopic group. Results Sixty-four cases were included in the analysis (44 open, 20 laparoscopic). Baseline characteristics were similar between the two groups with the exception that the open group, on average, underwent repair later than the laparoscopic group (6 days versus 4 days, respectively). Seven laparoscopic cases were converted to an open procedure (35%), most commonly for difficulty in exposing the decompressed distal duodenum. Laparoscopic repair did take significantly longer than open repair (145 minutes versus 96 minutes, respectively), but clinical outcomes were similar. Complications were rare and were similar between methods of repair. Two patients in the laparoscopic group required subsequent open revision. Conclusions Laparoscopic duodenoduodenostomy for congenital duodenal obstruction is a technically challenging procedure with a steep learning curve. Despite a relatively high conversion rate, clinical outcomes remained similar to the traditional open repair in selected patients. PMID:24079961

    Laparoscopically assisted splenectomy with an 8- to 10-cm left upper paramedian laparotomy was performed following preoperative splenic artery embolization using painless contour emboli (super absorbent polymer microsphere) with early successful results in two men (46 and 37 years old) with myelofibrosis accompanied by massive splenomegaly. Dissection around the lower part of the spleen and the hilum initially was performed intracorporeally with the usual laparoscopic view under 12 mm Hg pneumoperitoneum. The alternating changes of viewpoints between the direct view through an 8- to 10-cm incision and the usual laparoscopic view with or without application of a retraction method were effective for safe hilar devascularization. Preoperative splenic artery embolization at the distal site was effective for safe dissection around the enlarged spleen. The patients did not complain of pain before operation. Preoperative painless embolization and laparoscopically assisted splenectomy with small laparotomy promotes the feasibility and safety of minimally invasive splenectomy for myelofibrosis with massive splenomegaly.

    BACKGROUND: Performing a surgical procedure in weightlessness has been shown not to be any more difficult than in a 1g environment if the requirements for the restraint of the patient, operator, and surgical hardware are observed. The feasibility of performing a laparoscopic surgical procedure in weightlessness, however, has been questionable. Concerns have included the impaired visualization from the lack of gravitational retraction of the bowel and from floating debris such as blood. METHODS: In this project, laparoscopic surgery was performed on a porcine animal model in the weightlessness of parabolic flight. RESULTS: Visualization was unaffected due to the tethering of the bowel by the elastic mesentery and the strong tendency for debris and blood to adhere to the abdominal wall due to surface tension forces. CONCLUSIONS: There are advantages to performing a laparoscopic instead of an open surgical procedure in a weightless environment. These will become important as the laparoscopic support hardware is miniaturized from its present form, as laparoscopic technology becomes more advanced, and as more surgically capable crew medical officers are present in future long-duration space-exploration missions.

These procedures have clear anatomic view in the operation and preoperatively undiagnosed femoral hernia could be confirmed and treated. Lower recurrence ratio was reported in laparoscopic procedures compared with open procedures for repair of femoral hernia. The technical details of laparoscopic repair of femoral hernia, especially the differences to laparoscopic repair of inguinal hernia are discussed in this article. PMID:27826574

    Nowadays surgical trainees are faced with a more reduced surgical practice, due to legal limitations and work hourly constraints. Also, currently surgeons are expected to dominate more complex techniques such as laparoscopy. Simulation emerges as a complementary learning tool in laparoscopic surgery, by training in a safe, controlled and standardized environment, without jeopardizing patient' safety. Simulation' objective is that the skills acquired should be transferred to the operating room, allowing reduction of learning curves. The use of simulation has increased worldwide, becoming an important tool in different surgical residency programs and laparoscopic training courses. For several countries, the approval of these training courses are a prerequisite for the acquisition of surgeon title certifications. This article reviews the most important aspects of simulation in laparoscopic surgery, including the most used simulators and training programs, as well as the learning methodologies and the different key ways to assess learning in simulation.

    OBJECTIVE: The goal of this study was to prospectively define the impact of laparoscopy on the management of patients with a presumed diagnosis of appendicitis. SUMMARY BACKGROUND DATA: While the role of laparoscopy in the management of cholelithiasis is well established, its impact on the management of acute appendicitis needs to be objectively defined and compared to that of conventional management. Several authors have predicted that laparoscopic appendectomy will become the preferred treatment for appendicitis. METHODS: Two groups of consecutive patients with similar clinical characteristics of acute appendicitis were compared. Data on the laparoscopic group were compiled prospectively on standardized forms; data on the conventional group were collected retrospectively. Operative time, hospital stay, analgesia, cost, and return to normal activities were noted. RESULTS: Seventeen consecutive patients who underwent appendectomy were compared to 18 consecutive patients who underwent laparoscopy (16 of these 18 had laparoscopic appendectomy). There was no significant difference between the two groups in terms of clinical characteristics and appendiceal histopathology. The mean operative times were 61 +/- 4.1 minutes and 46 +/- 2.9 minutes for the laparoscopy and conventional groups, respectively (p < 0.01). Hospital stay was significantly shorter in the laparoscopic appendectomy group, with 81% of patients being discharged on their first postoperative day (p < 0.001). The laparoscopic appendectomy patients required significantly less narcotic analgesia (p < 0.02). Return to normal activity was not significantly different between the two groups. The average total cost of laparoscopic appendectomy was 30% greater than that of conventional appendectomy. CONCLUSIONS: Laparoscopy is a useful adjunct to the management of patients with a presumed clinical diagnosis of acute appendicitis. PMID:8239785

    Purpose: The effectiveness of angiography and embolization in diagnosis and treatment were assessed in a cohort of patients presenting with upper gastrointestinal hemorrhage secondary to hepatic artery pseudoaneurysm following laparoscopic cholecystectomy. Methods: Over a 6-year period 1513 laparoscopic cholecystectomies were carried out in our region. Nine of these patients (0.6%) developed significant upper gastrointestinal bleeding, 5-43 days after surgery. All underwent emergency celiac and selective right hepatic artery angiography. All were treated by coil embolization of the right hepatic artery proximal and distal to the bleeding point. Results: Pseudoaneurysms of the hepatic artery adjacent to cholecystectomy clips were demonstrated in all nine patients at selective right hepatic angiography. In three patients celiac axis angiography alone failed to demonstrate the pseudoaneurysm. Embolization controlled hemorrhage in all patients with no further bleeding and no further intervention. One patient developed a candidal liver abscess in the post-procedure period. All patients are alive and well at follow-up. Conclusion: Selective right hepatic angiography is vital in the diagnosis of upper gastrointestinal hemorrhage following laparoscopic cholecystectomy. Embolization offers the advantage of minimally invasive treatment in unstable patients, does not disrupt recent biliary reconstruction, allows distal as well as proximal control of the hepatic artery, and is an effective treatment for this potentially life-threatening complication.

    Introduction. Laparoscopic Sleeve Gastrectomy (SG) is considered as successful if the percentage of Excess Body Mass Index Loss (% EBMIL) remains constant over 50% with long-term follow-up. The aim of this study was to evaluate whether early % EBMIL was predictive of success after SG. Methods. This retrospective study included patients who had SG with two years of follow-up. Patients had follow-up appointments at 3 (M3), 6, 12, and 24 months (M24). Data as weight and Body Mass Index (BMI) were collected systematically. We estimated the % EBMIL necessary to establish a correlation between M3 and M24 compared to % EBMIL speeds and calculated a limit value of % EBMIL predictive of success. Results. Data at operative time, M3, and M24 were available for 128 patients. Pearson test showed a correlation between % EBMIL at M3 and that at M24 (r = 0.74; p < 0.0001). % EBMIL speed between surgery and M3 (p = 0.0011) was significant but not between M3 and M24. A linear regression analysis proved that % EBMIL over 20.1% at M3 (p < 0.0001) predicted a final % EBMIL over 50%. Conclusions. % EBMIL at M3 after SG is correlated with % EBMIL in the long term. % EBMIL speed was significant in the first 3 months. % EBMIL over 20.1% at M3 leads to the success of SG.

    INTRODUCTION: Safe, effective weight loss with resolution of comorbidities has been convincingly demonstrated with bariatric surgery in the aged obese. They, however, lose less weight than younger individuals. It is not known if degree of weight loss is influenced by the choice of bariatric procedure. The aim of this study was to compare the degree of weight loss between laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients above the age of 50 years at 1 year after surgery. MATERIALS AND METHODS: A retrospective analysis was performed of all patients more than 50 years of age who underwent LSG or LRYGB between February 2012 and July 2013 with at least 1 year of follow-up. Data evaluated at 1 year included age, sex, weight, body mass index (BMI), mean operative time, percentage of weight loss and excess weight loss, resolution/remission of diabetes, morbidity and mortality. RESULTS: Of a total of 86 patients, 54 underwent LSG and 32 underwent LRYGB. The mean percentage of excess weight loss at the end of 1 year was 60.19 ± 17.45 % after LSG and 82.76 ± 34.26 % after LRYGB (P = 0.021). One patient developed a sleeve leak after LSG, and 2 developed iron deficiency anaemia after LRYGB. The remission/improvement in diabetes mellitus and biochemistry was similar. CONCLUSION: LRYGB may offer better results than LSG in terms of weight loss in patients over 50 years of age. PMID:27279392

    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

    A computer-based simulation system creates a visual and haptic virtual environment for training a medical practitioner in laparoscopic surgery. Heretofore, it has been common practice to perform training in partial laparoscopic surgical procedures by use of a laparoscopic training box that encloses a pair of laparoscopic tools, objects to be manipulated by the tools, and an endoscopic video camera. However, the surgical procedures simulated by use of a training box are usually poor imitations of the actual ones. The present computer-based system improves training by presenting a more realistic simulated environment to the trainee. The system includes a computer monitor that displays a real-time image of the affected interior region of the patient, showing laparoscopic instruments interacting with organs and tissues, as would be viewed by use of an endoscopic video camera and displayed to a surgeon during a laparoscopic operation. The system also includes laparoscopic tools that the trainee manipulates while observing the image on the computer monitor (see figure). The instrumentation on the tools consists of (1) position and orientation sensors that provide input data for the simulation and (2) actuators that provide force feedback to simulate the contact forces between the tools and tissues. The simulation software includes components that model the geometries of surgical tools, components that model the geometries and physical behaviors of soft tissues, and components that detect collisions between them. Using the measured positions and orientations of the tools, the software detects whether they are in contact with tissues. In the event of contact, the deformations of the tissues and contact forces are computed by use of the geometric and physical models. The image on the computer screen shows tissues deformed accordingly, while the actuators apply the corresponding forces to the distal ends of the tools. For the purpose of demonstration, the system has been set

    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.

    Anesthesiologists currently view laparoscopic cholecystectomy resemblant to other laparoscopic procedures with respect to the necessity of inducing a pneumoperitoneum via abdominal insufflation of carbon dioxide (CO2). The present case report describes a healthy 63-year-old man who while undergoing elective laparoscopic cholecystectomy under general anesthesia, developed hypoxemia in the course in consequence of pneumothorax. This complication, although rare, can be catastrophic if prompt diagnosis and rapid intervention and management do not come in the nick of time.

    Radical cystectomy remains the standard treatment for muscle invasive organ confined bladder carcinoma. Laparoscopic radical cystoprostatectomy (LRC) is an advanced laparoscopic procedure that places significant demands on the patient and the surgeon alike. It is a prolonged procedure which includes several technical steps and requires highly developed laparoscopic skills including intra-corporeal suturing. Here we review the development of the technique, the indications, complications and outcomes. We also examine the potential benefits of robotic-assisted LRC and explore the indications and technique of laparoscopic partial cystectomy. PMID:21206662

    We performed 417 laparoscopic cholecystectomies, including 58 for acute cholecystitis, between September 1991 and April 1995,. All operations were successful, with no mortality or complications. In about 10%, the laparoscopic approach failed and we converted to open cholecystectomy. Average post-operative hospitalization was 24 hours. We also performed primary open cholecystectomies in 55 patients with acute cholecystitis, because of limitations of operating room and staff availability for unscheduled laparoscopic surgery. In these patients, hospital stay was longer and rate of complications higher. In our opinion laparoscopic cholecystectomy is safe and the preferred approach in acute cholecystitis.

    Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

    Abstract Background: In some studies, gum-chewing was demonstrated to have a beneficial effect on resumption of bowel function; however, other contradictory findings in other studies refute the effects of gum-chewing on peristaltic movements and digestive system stimulation. In addition, most previous studies were after colorectal or gynecology surgery, whereas few reports focused on the effect of gum-chewing after gastrectomy. The aim of this randomized controlled trial was to assess the effectiveness of gum-chewing on postoperative bowel function in patients who had undergone laparoscopic gastrectomy. Methods: From March 2014 to March 2016, 75 patients with gastric cancer received elective laparoscopic surgery in Shanghai Tongji hospital and were postoperatively randomly divided into 2 groups: 38 in a gum-chewing (Gum) group and 37 in a control (No gum) group. The patients in the Gum group chewed sugarless gum 3 times daily, each time for at least 15 minutes, until the day of postoperative exhaust defecation. Results: The mean time to first flatus (83.4 ± 35.6 vs. 79.2 ± 24.2 hours; P = 0.554) and the mean time to first defecation (125.7 ± 41.2 vs. 115.4 ± 34.2 hours; P = 0.192) were no different between the no gum and Gum groups. There was also no significant difference in the incidence of postoperative ileus (P = 0.896) and postoperative hospital stay (P = 0.109) between the 2 groups. The postoperative pain score at 48 hours (P = 0.032) in the Gum group was significantly higher than in the no gum group. There was no significant difference between the 2 groups in regards to patient demographics, comorbidities, duration of surgery, complications, and nausea/vomiting score. Conclusion: Gum-chewing after laparoscopic gastrectomy did not hasten the return of gastrointestinal function. In addition, gum-chewing may increase patient pain on the second postoperative day.

    Performing laparoscopic surgery requires an initial training program. A well-planned organization is essential and the surgeon has to become first familiar with the new procedures; the choice of the necessary equipment is the second step. Upkeep of surgical instruments and a careful consideration of legal aspects are the next important steps. Several areas of a planning program are evaluated on the basis of the authors' experience.

    Aim: To assess the modifications in the technique of laparoscopic assisted anorectal pull through (LAARP) practiced at our institute and analyze the post operative outcome and associated complications. Materials and Methods: A retrospective study from January 2001 to May 2009 analyzing LAARP for high anorectal malformations. Results: A total of 40 patients - 34 males and six females, in the age group of two months to six years were studied. Staged procedure was done in 39 patients; one child with recto vestibular fistula underwent single stage procedure. All the patients withstood surgery well. One patient required conversion due to problems in gaining enough length for the distal rectum in a patient with rectovesical fistula so colostomy was closed and re-located at a proximal splenic flexure. The complications were mucosal prolapse (six cases), anal stenosis (three), adhesive obstruction (two), distal rectal necrosis (one), and urethral diverticulum (one). The patients were followed up with clinical evaluation and continence scoring. The progress has been satisfactory and weight-gain is adequate. Conclusions: The advantages of the reformed techniques are as follows: Transcutaneous bladder stitch provides excellent visualization; traction over the fistula helps in dissection of the puborectalis, dividing the fistula without ligation is safe, railroading of Hegar's dilators over the suction canula creates adequate pull through channel, saves time and makes procedure simpler with reproducible comparable reports.

    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

    Immunological response to surgical trauma may be protected during laparoscopic surgery. A less surgical trauma, in comparison with conventional surgery, may explained these important advantages. Plasma and macrophages studies have demonstrated that laparoscopic cholecystectomy causes less depression of cell mediated immunity than open cholecystectomy. What will be the impact of this immunological protection in laparoscopic advanced and oncological surgery? Experimental studies have showed that laparoscopic techniques in advanced and oncological surgery may have important advantages concerning the "preservation of the immune status" of the patient. That will imply in the future a lower percentage of infections, local recurrence and even a lower percentage of distant metastases. On the other hand, the appearance of tumor implants in the port sites after laparoscopic resection for cancer is a significant drawback of this procedure. Proper investigations have to be carried out in order to find the cause and the solution of this dilemma.

    Pelvic node dissection has gained widespread acceptance as the final staging procedure in patients with normal acid phospatase and bone scan free of metastatic disease prior to definitive therapy for cure. However, the procedure has had a high morbidity (20-34%) and a major economic impact on the patient due to lengthy hospitalization and recuperative time. The development of laparoscopic biopsy techniques suggests that the need for open surgical lymphadenectomy may be reduced by a laparoscopically performed lymphadenectomy. The goal of this report is to investigate the possibility of laparoscopic pelvic lymphadenectomy in an animal model. Our interest in laparoscopy is based on the ability of this technique to permit tissue removal without the need for major incisions. In laparoscopic cholecystectomy and laparoscopic appendectomy, the surgical procedure is essentially unaltered. The diseased organ is removed and there is no need for a large abdominal incision.

    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.

    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

    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.

    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.

    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

    Background Liver resection is reputed to be one of the most difficult procedures embraced in laparoscopy. This report shows that with adequate training, anatomical liver resection including major hepatectomies can be performed. Methods This is a retrospective study. Results From 1995 to 2004, among 84 laparoscopic liver resections, 46 (54%) anatomical laparoscopic hepatectomies were performed in our institution by laparoscopy. Nine (20%) patients had benign disease while 37 (80%) had malignant lesions. Among those with malignant lesions, 14 patients had hepatocellular carcinoma (HCC), 18 had colorectal metastasis (CRM), while 5 had miscellaneous tumours. For benign disease, minor (two Couinaud's segments or less) and major anatomic hepatectomies were performed in five and four patients, respectively. For malignant lesions, minor and major anatomic hepatectomies were performed in 15 and 22 patients, respectively. Overall, conversion to laparotomy was necessary in 7 (15%) patients. Blood transfusion was required in five (10%) patients. One patient died of cerebral infarction 8 days after a massive peroperative haemorrhage. The overall morbidity rate was 34% whatever the type of resection. Three patients required reoperation, either for haemorrhage (n=1) and/or biliary leak (n=2). For CRM (n=18), overall and disease-free survival at 24 months (mean follow-up of 17 months) were 100% and 56%, respectively. For HCC (n=14), overall and disease-free survival at 36 months (mean follow-up of 29 months) were 91% and 65%, respectively. No port site metastasis occurred in patients with malignancy. Conclusions After a long training with limited liver resection in superficial segments, laparoscopic anatomical minor and major resections are feasible. Short-term carcinological results seem to be similar to those obtained with laparotomy. PMID:18333079

    Laparoscopic cholecystectomy was performed on 65 unselected and consecutive patients, regardless of age, weight, history of abdominal surgery or presence of acute cholecystitis. All procedures were completed successfully, with only two patients converted to an open cholecystectomy. There were no intra-abdominal intraoperative complications; n o intraoperative transfusions were required. There were no intra-abdominal injuries, and no patient required repeat surgery for postoperative complications. Hospital stays averaged 30 hours, and the average time until patients resumed normal activities was 6 days.

    Laparoscopic CBD exploration (LCBDE) is a cost effective, efficient and minimally invasive method of treating choledocholithiasis. Laparoscopic Surgery for common bile duct stones (CBDS) was first described in 1991, Petelin (Surg Endosc 17:1705-1715, 2003). The surgical technique has evolved since then and several studies have concluded that Laparoscopic common bile duct exploration(LCBDE) procedures are superior to sequential endolaparoscopic treatment in terms of both clinical and economical outcomes, Cuschieri et al. (Surg Endosc 13:952-957, 1999), Rhodes et al. (Lancet 351:159-161, 1998). We started doing LCBDE in 1998.Our experience with LCBDE from 1998 to 2004 has been published, Gupta and Bhartia (Indian J Surg 67:94-99, 2005). Here we present our series from January 2005 to March 2009. In a retrospective study from January 2005 to March 2009, we performed 3060 laparoscopic cholecystectomies, out of which 342 patients underwent intraoperative cholangiogram and 158 patients eventually had CBD exploration. 6 patients were converted to open due to presence of multiple stones and 2 patients were converted because of difficulty in defining Calots triangle; 42 patients underwent transcystic clearance, 106 patients had choledochotomy, 20 patients had primary closure of CBD whereas in 86 patients CBD was closed over T-tube; 2 patients had incomplete stone clearance and underwent postoperative ERCP. Choledochoduodenosotomy was done in 2 patients. Patients were followed regularly at six monthly intervals with a range of six months to three years of follow-up. There were no major complications like bile leak or pancreatitis. 8 patients had port-site minor infection which settled with conservative treatment. There were no cases of retained stones or intraabdominal infection. The mean length of hospital stay was 3 days (range 2-8 days). LCBDE remains an efficient, safe, cost-effective method of treating CBDS. Primary closure of choledochotomy in select patients is a

    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

    The aim of this study is the evaluation of laparoscopic treatment in abdominal complications following ventriculoperitoneal (VP) shunt. Methods: We report a retrospective study including 17 patients with abdominal complications secondary to VP shunt for hydrocephalus, laparoscopically treated in our department, between 2000 and 2007. Results: Patients' age ranged from 1 to 72 years old (mean age 25.8 years old). Male: female ratio was 1.4. Abdominal complications encountered were: shunt disconnection with intraperitoneal distal catheter migration 47.05% (8/17), infections 23.52% (4/17) such as abscesses and peritonitis, pseudocysts 11.76% (2/17), CSF ascites 5.88% (1/17), inguinal hernia 5.88% (1/17), and shunt malfunction due to excessive length of intraperitoneal tube 5.88% (1/17). Free–disease interval varies from 1 day to 21 years, depending on the type of complication, short in peritoneal irritation syndrome and abscesses (days) and long in ascites, pseudocysts(months– years). Laparoscopic treatment was: extraction of the foreign body in shunt disconnection with intraperitoneal distal catheter migration, evacuation, debridement, lavage and drainage for pseudocysts, abscess and peritonitis, shortening of the tube in shunt malfunction due to excessive length of intraperitoneal tube a nd hernioraphy. One diagnostic laparoscopy was performed in a peritoneal irritation syndrome, which found only CSF ascites. There were no conversions to open surgery. The overall mortality was of 5.88% and postoperative morbidity was of 11.76%. In 7 patients operated for abscesses, peritonitis, pseudocysts, and CSF ascites the shunting system was converted in to a ventriculocardiac shunt. Conclusions: Abdominal complication following VP shunt can be successfully performed laparoscopically. Abdominal surgery required, in selected cases, the repositioning of the distal catheter, frequently as a ventriculocardiac shunt. There are abdominal complications with no indication of

    A technique for laparoscopic Nissen fundoplication is described and a series of 11 cases is presented. The technique secures the patient to the operating table with three safety straps and the patient is then placed in a reverse Trendelenburg position with the hips flexed. The surgeon operates from the patient's right side using two midline trocar sites as the main operating ports. Other ports provide retraction and laparoscope access. The liver retractor is held by a mechanical arm. Once the esophageal peritoneum has been opened, the esophagus and diaphragmatic crura are dissected out and elevated by a Penrose drain sling. The short gastrics are divided and the fundus is brought posterior to the esophagus passing from left to right. A large Maloney dilator is placed in the esophagus and the fundal wrap is sutured to the anterior aspect of the stomach by three sutures; the inferior--most of which incorporates the anterior wall of the esophagus. Once the fundoplication is completed, the dilator is replaced by a nasogastric tube. Postoperatively, patients are given clear liquids and when these are tolerated the nasogastric tube is removed. Most patients are discharged on the second or third postoperative day. Operating time averaged 147 min, and all patients returned to unrestricted activity within 2 to 3 weeks. All patients reported complete relief of gastroesophageal reflux. Average follow up was 120 days with a median of 148 days. Long-term follow up is in progress.

    Laparoscopic live donor nephrectomy (LDN) has removed disincentives of potential donors and may bear the potential to increase kidney donation. Multiple modifications have been made to abbreviate the learning curve while at the same time guarantee the highest possible level of medical quality for donor and recipient. We reviewed the literature for the evolution of the different LDN techniques and their impact on donor, graft and operating surgeon, including the subtleties of different surgical accesses, vessel handling and organ extraction. We performed a literature search (PubMed, DIMDI, medline) to evaluate the development of the LDN techniques from 1995 to 2003. Today more than 200 centres worldwide perform LDN. Hand-assistance has led to a spread of LDN. Studies comparing open and hand-assisted LDN show a reduction of operating and warm ischaemia times for the hand-assisted LDN. Different surgical access sites (trans- or retroperitoneal), different vessel dissection approaches, donor organ delivery techniques, delivery sites and variations of hand-assistance techniques reflect the evolution of LDN. Proper techniques and their combination for the consecutive surgical steps minimize both warm ischaemia time and operating time while offering the donor a safe minimally invasive laparoscopic procedure. LDN has breathed new life into the moribund field of living kidney donation. Within a few years LDN could become the standard approach in living kidney donation. Surgeons working in this field must be trained thoroughly and well acquainted with the subtleties of the different LDN techniques and their respective advantages and disadvantages.

    On the basis of literature and of 475 laparoscopic cholecystectomies of the authors, some pitfalls are reviewed. The circumstances, the mechanism and the prevention of injuries were detailed together with the connected problem of postoperative bile leakage. Among the cholangiographic pitfalls the importance of detection of congenital and acquired anomalies of the biliary tree by means of preoperative ERCP or intraoperative trans-cystic cholangiograms was emphasized. A particular study was made of 3 pictures: Mirizzi syndrome; stone impaction in Vater's papilla; no retrograde flow of the common hepatic duct on intraoperative cholangiograms. Biliodigestive fistulas were briefly commented. The problems with cystic duct stones, particularly the treatment of stones in a long, low inserted cystic duct with retroduodenal course and the closing of thick-walled or wide cystic stumps, were explained. In patients with intraoperative residual common bile duct stones and with failed preoperative catheterization of the papilla, the authors advocate their double approach technique. This combined intraoperative laparoscopic and postoperative endoscopic procedure is carried out via the same transcystic polythene catheters as used for cholangiography and external biliary drainage of the common bile duct.

    Since corticosteroids are indispensable hormones, partial or cortical-sparing adrenalectomies may be adopted for the surgical treatment of adrenal diseases. In this article, we describe the technique and results of these procedures. Laparoscopic partial or cortical-sparing adrenalectomy has been performed in 10 patients. Seven cases had an aldosterone-producing adenoma (APA) and three had a pheochromocytoma. Three cases with an APA and a case with a pheochromocytoma had tumors located far from the adrenal central vein, and the vein could be preserved. Four cases with an APA and two with a pheochromocytoma had tumors located close to the adrenal central vein, and it was necessary to section the central vein to resect them. All endoscopic procedures were performed successfully. There were no postoperative complications. At follow-up, adrenal 131I-adosterol scintigrams showed the preservation of remnant adrenal function in all patients. Laparoscopic partial or cortical-sparing adrenal surgery was safely performed, and adrenal function was preserved irrespective of whether the adrenal central vein could be preserved or not. We consider this to be a useful operative technique for selected cases.

    Background and Objectives: Surgeons constantly struggle with the formation of condensation on the lens of a laparoscope, which prolongs procedures and reduces visibility of the abdominal cavity. The goal of this project was to build a device that would direct a flow of carbon dioxide (CO2) into an open chamber surrounding the lens of a laparoscope, acting to keep moisture away from the lens and eliminate condensation. Methods: The device isolates the lens of the laparoscope from the humid environment of the intraperitoneal cavity by creating a microenvironment of dry CO2. This was accomplished by building a communicating sleeve that created an open chamber around the distal 2 to 3 cm of the scope. Into this cavity, dry cool CO2 was pumped in from an insufflator so that the path of the gas would surround the lens of the scope and escape through a single outlet location through which the scope views the intraperitoneal cavity. This chamber is proposed to isolate the lens with a high percentage of dry CO2 and low humidity. The device was tested in 7 different adverse conditions that were meant to challenge the ability of the device to maintain the viewing field with no perceptible obstruction. Results: In all of the conditions tested, 25 trials total, the device successfully prevented and/or eliminated laparoscopic lens fogging. Conclusions: The device designed for this project points to the potential of a simple and effective mechanical method for eliminating laparoscopic lens fogging. PMID:24680144

    The laparoscopic surgery has gained presence in the operating room in cases where it is feasible to spare patient trauma and minimize the hospital stay. One unique challenge in laparoscopic/endoscopic surgery is operating and removing tissue volume through keyhole - trocar. The removal of tissues by fragmentation is generally termed morcellation. We proposed a new method for soft tissue morcellation using laparoscopy. A unique ultrasonic laparoscopic surgical device, termed Laparosound{trade mark, serif}, utilizing laparoscopic high amplitude ultrasonic waveguides, operating in edge mode, has been developed that uses the principle of ultrasonic cavitation phenomenon for excision and morcellation of a variety of tissue types. The local ultrasonic acoustic intensity at the distal waveguide tip is sufficiently high that the liquefaction of moist tissue occurs. The mechanism of tissue morcellation is deemed to be cavitation based, therefore is dependant on water content in tissue, and thus its effectiveness depends on tissue type. This results in ultrasound being efficient in moist tissue and sparing dry, collagen rich blood vessels and thus minimizes bleeding. The applications of such device in particular, commonly encountered, could lay in general and ob/gyn laparoscopic surgery, whereas other applications could emerge. The design of power ultrasonic instruments for mass clinical applications poses however unique challenges, such as ability to design and build ultrasonic resonators that last in conditions of ultrasonic fatigue. These highly non-linear devices, whose behavior is hard to predict, have become the challenge of the author of the present paper. The object of work is to design and build an operating device capable of ultrasonic soft tissue morcellation in laparoscopic surgery. This includes heavy computational ultrasonics verified by testing and manufacturing feasibility using titanium biomedical alloys. The prototype Laparosound{trade mark, serif} device

    Currently, endoscopic submucosal dissection (ESD) and laparoscopic gastrectomy (LG) have become widely accepted and increasingly play important roles in the treatment of gastric cancer. Data from an administrative database associated with the diagnosis procedure combination (DPC) system have revealed some circumstances of ESD and LG in Japan. Some studies demonstrated that medical costs or length of stay of patients receiving ESD for gastric cancer had become significantly reduced while length of hospitalization and costs were significantly increased in older patients. With respect to LG, some recent reports have shown that this has been a cost-beneficial treatment for patients compared with open gastrectomy while simultaneous LG and cholecystectomy is a safe procedure for patients with both gastric cancer and gallbladder stones. These epidemiological studies using the administrative database in the DPC system closely reflect clinical circumstances of endoscopic and surgical treatment for gastric cancer in Japan. However, DPC database does not contain detailed clinical data such as histological types and lesion size of gastric cancer. The link between the DPC database and another detailed clinical database may be vital for future research into endoscopic and laparoscopic treatments for gastric cancer.

    The transperitoneal laparoscopic approach for right adrenalectomy is performed in patients placed in a lateral decubitus position. Four ports are usually needed (2 or 3, 10 mm ports, 1 or 2, 5 mm ports), inserted in the right subcostal area. After liver retraction, the retroperitonéal space is opened close to the liver, exposing the right adrenal gland and the inferior vena cava. The periphrenic fat and the internal side of the gland are dissected close to the right side of the vena cava in order to expose the main adrenal vein. This vein is double clipped. At the inferior pole of the gland, the inferior adrenal artery is ligated with clips. Before removing and extracting the gland, the right side and the upper pole of the gland are dissected last.

    Twenty domestic pigs with an average weight of 30 kg were subjected to laparoscopic partial splenic resection with the aim of determining the feasibility, reliability, and safety of this procedure. Unlike the human spleen, the pig spleen is perpendicular to the body's long axis, and it is long and slender. The parenchyma was severed through the middle third, where the organ is thickest. An 18-mm trocar with a 60-mm Endopath linear cutter was used for the resection. The tissue was removed with a 33-mm trocar. The operation was successfully concluded in all animals. No capsule tears occurred as a result of applying the stapler. Optimal hemostasis was achieved on the resected edges in all animals. Although these findings cannot be extended to human surgery without reservations, we suggest that diagnostic partial resection and minor cyst resections are ideal initial indications for this minimally invasive approach.

    Background and Objectives: We aimed to assess the feasibility and outcomes of complex ureteropelvic junction obstruction cases submitted to robotic-assisted laparoscopic pyeloplasty. Methods: The records of 131 consecutive patients who underwent robotic-assisted laparoscopic pyeloplasty were reviewed. Of this initial population of cases, 17 were considered complex, consisting of either atypical anatomy (horseshoe kidneys in 3 patients) or previous ureteropelvic junction obstruction management (14 patients). The patients were divided into 2 groups: primary pyeloplasty (group 1) and complex cases (group 2). Results: The mean operative time was 117.3 ± 33.5 minutes in group 1 and 153.5 ± 31.1 minutes in group 2 (P = .002). The median hospital stay was 5.19 ± 1.66 days in group 1 and 5.90 ± 2.33 days in group 2 (P = .326). The surgical findings included 53 crossing vessels in group 1 and 5 in group 2. One patient in group 1 required conversion to open surgery because of technical difficulties. One patient in group 2, with a history of hemorrhagic rectocolitis, presented with peritonitis postoperatively due to a small colonic injury. A secondary procedure was performed after the patient had an uneventful recovery. At 3 months, significant improvement (clinical and radiologic) was present in 93% of cases in group 1 and 88.2% in group 2. At 1 year, all patients in group 2 showed satisfactory results. At a late follow-up visit, 1 patient in group 1 presented with a recurrent obstruction. Conclusions: Robotic pyeloplasty appear to be feasible and effective, showing a consistent success rate even in complex situations. Particular care should be observed during the colon dissection in patients with previous colonic pathology. PMID:24680152

    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

    Introduction Traditionally, laparoscopic mesh rectopexy is performed with four ports, in an attempt to improve cosmetic results. Following laparoscopic mesh rectopexy there is a new operative technique called single-port laparoscopic mesh rectopexy. Aim To evaluate the single-port laparoscopic mesh rectopexy technique in control of rectal prolapse and the cosmesis and body image issues of this technique. Material and methods The study was conducted in El Fayoum University Hospital between July 2013 and November 2014 in elective surgery for symptomatic rectal prolapse with single-port laparoscopic mesh rectopexy on 10 patients. Results The study included 10 patients: 3 (30%) males and 7 (70%) females. Their ages ranged between 19 years and 60 years (mean: 40.3 ±6 years), and they all underwent laparoscopic mesh rectopexy. There were no conversions to open technique, nor injuries to the rectum or bowel, and there were no mortalities. Mean operative time was 120 min (range: 90–150 min), and mean hospital stay was 2 days (range: 1–3 days). Preoperatively, incontinence was seen in 5 (50%) patients and constipation in 4 (40%). Postoperatively, improvement in these symptoms was seen in 3 (60%) patients for incontinence and in 3 (75%) for constipation. Follow-up was done for 6 months and no recurrence was found with better cosmetic appearance for all patients. Conclusions Single-port laparoscopic mesh rectopexy is a safe procedure with good results as regards operative time, improvement in bowel function, morbidity, cost, and recurrence, and with better cosmetic appearance.

    Introduction The benefits of antireflux surgery are well established. Laparoscopic techniques have been shown to be generally safe and effective. The aim of this paper was to review the subject of pain following laparoscopic antireflux surgery. Methods A systematic review of the literature was conducted using the PubMed database to identify all studies reporting pain after laparoscopic antireflux surgery. Publications were included for the main analysis if they contained at least 30 patients. Operations in children, Collis gastroplasty procedures, endoluminal fundoplication and surgery for paraoesophageal hernias were excluded. The frequency of postoperative pain was calculated and the causes/management were reviewed. An algorithm for the investigation of patients with pain following laparoscopic fundoplication was constructed. Results A total of 17 studies were included in the main analysis. Abdominal pain and chest pain following laparoscopic fundoplication were reported in 24.0% and 19.5% of patients respectively. Pain was mild or moderate in the majority and severe in 4%. Frequency of pain was not associated with operation type. The authors include their experience in managing patients with persistent, severe epigastric pain following laparoscopic anterior fundoplication. Conclusions Pain following laparoscopic antireflux surgery occurs in over 20% of patients. Some have an obvious complication or a diagnosis made through routine investigation. Most have mild to moderate pain with minimal effect on quality of life. In a smaller proportion of patients, pain is severe, persistent and can be disabling. In this group, diagnosis is more difficult but systematic investigation can be rewarding, and can enable appropriate and successful treatment. PMID:24780664

    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.

    Background and Objectives: We present a case of Laparoendoscopic Single Site Surgery (LESS) left adrenalectomy performed with a conventional laparoscope and instruments. Methods: A 45-year-old male was diagnosed with hyperaldosteronism. Computed tomography detected a left adrenal nodule. Bilateral adrenal vein sampling was consistent with a left-sided source for hyperaldosteronism. Results: Total operative time for LESS left adrenalectomy was 120 minutes. The surgery was performed with conventional instruments, a standard 5-mm laparoscope, and a SILS port, with no additional incisions or trocars needed. No complications occurred, and the patient reported an uneventful recovery. Conclusions: LESS adrenalectomy is a feasible procedure. Although articulating instruments and laparoscopes may offer advantages, LESS adrenalectomy can be done without these. PMID:21902983

    This review focuses on the laparoscopic approach to gastrointestinal emergencies and its more recent indications. Laparoscopic surgery has a specific place in elective procedures, but that does not apply in emergency situations. In specific emergencies, there is a huge range of indications and different techniques to apply, and not all of them are equally settle. We consider that the most controversial points in minimally invasive procedures are indications in emergency situations due to technical difficulties. Some pathologies, such as oesophageal emergencies, obstruction due to colon cancer, abdominal hernias or incarcerated postsurgical hernias, are nearly always resolved by conventional surgery, that is, an open approach due to limited intraabdominal cavity space or due to the vulnerability of the bowel. These technical problems have been solved in many diseases, such as for perforated peptic ulcer or acute appendectomy for which a laparoscopic approach has become a well-known and globally supported procedure. On the other hand, endoscopic procedures have acquired further indications, relegating surgical solutions to a second place; this happens in cholangitis or pancreatic abscess drainage. This endoluminal approach avoids the need for laparoscopic development in these diseases. Nevertheless, new instruments and new technologies could extend the laparoscopic approach to a broader array of potentials procedures. There remains, however, a long way to go. PMID:26973409

    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.

    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

    Spilled gallstones have emerged as a new issue in the era of laparoscopic cholecystectomy. We treated a 77-year-old woman who underwent laparoscopic cholecystectomy. Subsequently, a right flank abscess developed. During the cholecystectomy, the gallbladder was perforated and stones were spilled. After a failed attempt to drain the abscess percutaneously, the patient required open drainage, which revealed retained gallstones in the right flank. The abscess resolved, although the patient continued to have intermittent drainage without evidence of sepsis. Review of the literature revealed 127 cases of spilled gallstones, of which 44.1% presented with intraperitoneal abscess, 18.1% with abdominal wall abscess, 11.8% with thoracic abscess, 10.2% with retroperitoneal abscess, and the rest with various clinical pictures. In case of gallstone spillage during laparoscopic cholecystectomy, every effort should be made to locate and retrieve the stones.

    The purpose of this study was to evaluate the results of a laparoscopic approach to recurrent inguinal hernia repair which dissected the entire inguinal floor and repaired all potential areas of recurrence without producing tension. Both a transabdominal preperitoneal and a totally extraperitoneal laparoscopic approach were utilized. Ninety recurrent hernias were repaired in 81 patients. The patients had 26 indirect, 36 direct, and 26 pantaloon recurrent hernias of which eight had a femoral component. In all but one patient the primary operations were open anterior repairs. The median follow-up was 14 months, ranging from 1 to 28 months. Patients returned to normal activities in an average of 1 week. The only recurrence observed was in the one patient whose primary repair was laparoscopic. When the entire inguinal floor of the recurrent hernia was redissected and buttressed with mesh, early recurrence was eliminated and recovery was shortened.

    Indications for transduodenal sphincterotomy have been reduced in recent years, mainly because of the development of endoscopic sphincterotomy and laparoscopic procedures. Endoscopic treatment is effective, but it is necessary to carefully evaluate its indications because the incidence of early and late complications is not negligible. Laparoscopic procedures require advanced and expensive technologies and considerable laparoscopic experience. Transduodenal sphincterotomy is safe and effective, if correctly performed. Some risk factors appear to be related to the incidence of complications that do not significantly differ from those following endoscopic sphincterotomy. Transduodenal sphincterotomy may be still indicated in selected cases, and for this reason it should be considered an essential part of the knowledge of a general surgeon.

    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

    With advancements in minimal access surgery, combined laparoscopic procedures are now being performed for treating coexisting abdominal pathologies at the same surgery. In our center, we performed 145 combined surgical procedures from January 1999 to December 2002. Of the 145 procedures, 130 were combined laparoscopic/endoscopic procedures and 15 were open procedures combined with endoscopic procedures. The combination included laparoscopic cholecystectomy, various hernia repairs, and gynecological procedures like hysterectomy, salpingectomy, ovarian cystectomy, tubal ligation, urological procedures, fundoplication, splenectomy, hemicolectomy, and cystogastrostomy. In the same period, 40 patients who had undergone laparoscopic cholecystectomy and 40 patients who had undergone ventral hernia repair were randomly selected for comparison of intraoperative outcomes with a combined procedure group. All the combined surgical procedures were performed successfully. The most common procedure was laparoscopic cholecystectomy with another endoscopic procedure in 129 patients. The mean operative time was 100 minutes (range 30-280 minutes). The longest time was taken for the patient who had undergone laparoscopic splenectomy with renal transplant (280 minutes). The mean hospital stay was 3.2 days (range 1-21 days). The pain experienced in the postoperative period measured on the visual analogue scale ranged from 2 to 5 with a mean of 3.1. Of 145 patients who underwent combined surgical procedures, 5 patients developed fever in the immediate postoperative period, 7 patients had port site hematoma, 5 patients developed wound sepsis, and 10 patients had urinary retention. As long as the basic surgical principles and indications for combined procedures are adhered to, more patients with concomitant pathologies can enjoy the benefit of minimal access surgery. Minimal access surgery is feasible and appears to have several advantages in simultaneous management of two different

    Reestablishing continuity after a Hartmann's procedure is considered a major surgical procedure with high morbidity/mortality. The aim of this study was to assess the short-/long-term outcome of laparoscopic restoration of bowel continuity after HP. A prospectively collected database of colorectal laparoscopic procedures (>800) performed between June 2005 and June 2013 was used to identify 20 consecutive patients who had undergone laparoscopic reversal of Hartmann's procedure (LHR). Median age was 65.4. Ten patients (50 %) had undergone surgery for perforated diverticulitis, 3 (15 %) for cancer, and 7 (35 %) for other reasons (volvulus, posttraumatic perforation, and sigmoid perforation from foreign body). Previous HP had been performed laparoscopically in only 3 patients. Median operative time was 162.5 min. All the procedures were completed laparoscopically. Intraoperative complication rate was nil. Post-operative mortality and morbidity were respectively 0 and 10 % (1 pneumonia, 1 bowel obstruction from post-anastomotic stenosis which required resection and redo of the anastomosis). Median time to first flatus was 3 days, to normal diet 5 days. Median hospital stay was 9 days without readmissions. We followed up the patients for a median of 44 months: when asked, all 20 (100 %) said they would undergo the operation (LHR) again; 3 (15 %) had been re-operated of laparoscopic mesh repair for incisional hernia. When performed by experienced surgeons, LHR is a feasible, safe, reproducible operation, which allows early return of bowel function, early discharge and fast return to work for the patient. It has a low morbidity rate.

    In light of evidence linking radical nephrectomy and consequent suboptimal renal function to adverse cardiovascular events and increased mortality, research into nephron-sparing techniques for renal masses widely expanded in the past two decades. The American Urological Association (AUA) guidelines now explicitly list partial nephrectomy as the standard of care for the management of T1a renal tumors. Because of the increasing utilization of cross-sectional imaging, up to 70% of newly detected renal masses are stage T1a, making them more amenable to minimally invasive nephron-sparing therapies including laparoscopic and robotic partial nephrectomy and ablative therapies. Cryosurgery has emerged as a leading option for renal ablation, and compared with surgical techniques it offers benefits in preserving renal function with fewer complications, shorter hospitalization times, and allows for quicker convalescence. A mature dataset exists at this time, with intermediate and long-term follow-up data available. Cryosurgical recommendations as a first-line therapy are made at this time in limited populations, including elderly patients, patients with multiple comorbidities, and those with a solitary kidney. As more data emerge on oncologic efficacy, and technical experience and the technology continue to improve, the application of this modality will likely be extended in future treatment guidelines.

    Laparoscopic surgery takes place in a closed environment, the peritoneal cavity distended by the pneumoperitoneum whose parameters, such as pressure, composition, humidity and temperature of the gas, may be changed and adapted to influence the intra and postoperative surgical processes. Such changes were impossible in the "open" environment. This review includes recent data on peritoneal physiology, which are relevant for surgeons, and on the effects of the pneumoperitoneum on the peritoneal membrane. The ability to work in a new surgical environment, which may be adapted to each situation, opens a new era in endoscopic surgery. Using nebulizers, the pneumoperitoneum may become a new way to administer intraoperative treatments. Most of the current data on the consequences of the pneumoperitoneum were obtained using poor animal models so that it remains difficult to estimate the progresses, which will be brought to the operative theater by this new concept. However this revolution will likely be used by thoracic or cardiac surgeon who are also working in a serosa. This approach may even appear essential to all the surgeons who are using endoscopy in a retroperitoneal space such as urologists or endocrine surgeons.

    The management of gastrointestinal malignancies continues to evolve with the latest available therapeutic and diagnostic modalities. There are currently two driving forces in the management of these cancers: the benefits of minimally invasive surgery so thoroughly demonstrated by laparoscopic surgery, and the shift toward neoadjuvant chemotherapy for upper gastrointestinal cancers. In order to match the appropriate treatment to the disease, accurate staging is imperative. No technological advances have combined these two needs as much as laparascopic ultrasound to evaluate the liver and peritoneal cavity. We present a concise review of the latest application of laparoscopic ultrasound in management of gastrointestinal malignancy.

    Parastomal hernia is one of the most common long-term complications after abdominal ostomy. Surgical treatment for parastomal hernia is the only cure but a fairly difficult field because of the problems of infection, effects, complications and recurrence. Laparoscopic repair operations are good choices for Parastomal hernia because of their mini-invasive nature and confirmed effects. There are several major laparoscopic procedures for parastomal hernioplasty. The indications, technical details and complications of them will be introduced and discussed in this article.

    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

    Ventriculoperitoneal shunt (VPS) surgery is the most commonly used method for the treatment of hydrocephalus. Traditionally, distal catheters in the VPS surgery have been placed either through a standard small open laparotomy or via a laparoscopic technique. Although there are many studies demonstrating the benefits of a minimally invasive approach, limited research has directly compared the two techniques used in VPS surgery. The present meta-analysis aims to provide the first comprehensive review of all published observational studies and randomized controlled trials reporting outcomes of laparotomy and laparoscopy in VPS. Electronic searches were performed using six databases from their inception to February 2015. Relevant studies comparing conventional laparotomy and a laparoscopic video-guided approach in VPS were included. Data were extracted and analyzed according to predefined clinical endpoints. A total of ten studies were identified for inclusion in the present analysis. Results indicated that the laparoscopic technique was associated with a slight but significant reduction in operating time (∼ 10 min), a significantly lower rate of abdominal malposition, distal obstruction and distal shunt failure. There was no difference between the laparotomic and laparoscopic approaches in the length of hospital stay, complication rate, proximal shunt failure or infection rate. The present systematic review and meta-analysis demonstrated that the laparoscopic technique in VPS surgery is associated with reduced shunt failure and abdominal malposition compared to the open laparotomy technique, with no significant difference in rates of infection or other complications. The lack of studies with high levels of evidence may contribute to bias in our conclusions and the long-term relative merits require validation by further prospective, randomized studies.

    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

    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.

  16. Stress response to laparoscopic liver resection

    2004-01-01

    Background: The magnitude of the systemic response is proportional to the degree of surgical trauma. Much has been reported in the literature comparing metabolic and immune responses, analgesia use, or length of hospital stay between laparoscopic and open procedures. In particular, metabolic and immune responses are represented by measuring various chemical mediators as stress responses. Laparoscopic procedures are associated with reduced operative trauma compared with open procedures, resulting in lower systemic response. As a result, laparoscopic procedures are now well accepted for both benign and malignant processes. Laparoscopic liver resection, specifically, is employed for symptomatic and some malignant tumors, following improvements in diagnostic accuracy, laparoscopic devices, and techniques. However, laparoscopic liver resection is still controversial in malignant disease because of complex anatomy, the technical difficulty of the procedure, and questionable indications. There are few reports describing the stress responses associated with laparoscopic liver resection, even though many studies reviewing stress responses have been performed recently in both humans and animal models comparing laparoscopic to conventional open surgery. Although this review examines stress response after laparoscopic liver resection in both an animal and human clinical model, further controlled randomized studies with additional investigations of immunologic parameters are needed to demonstrate the consequences of either minimally invasive surgery or open procedures on perioperative or postoperative stress responses for laparoscopic liver resection.

    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.

    Laparoscopic treatment of lesions of the distal pancreas has gained favour worldwide in the last decade. The objective of this study was to analyze 3 cases of insulinoma successfully treated with the laparoscopic approach. From 2000 to 2007 in our institution 3 patients with insulinoma of the left pancreas were treated with a laparoscopic approach. The insulinoma was diagnosed by helical CT scan, Two cases were treated by left pancreatectomy and one by enucleation. The resections were achieved by laparoscopy with no conversion to laparotomy. There were no intraoperative complications. Average blood loss was 180 mi (range: 150-350). Mean operative time was 232 minutes (range: 225-240). Morbidity consisted in one mild pancreatic fistula after left pancreatectomy that was healed by conservative treatment after 24 days. The mean hospital stay was 13 days (range: 10-20). During the follow-up insulinoma symptoms have disappeared in all patients. This study confirms the feasibility of laparoscopic resection for insulinoma. Operative times were quite acceptable and the conversion rate was nil. Times to oral intake and walking were shorter than after open surgery, as was the mean postoperative hospital stay.

    A 31-year-old healthy man presented with right lower quadrant pain and tenderness, mild neutrophilia and clinical presentation consistent with appendicitis, despite undergoing a laparoscopic appendicectomy 5 years prior. CT scan demonstrated a caecal phlegmon, in the expected region of the appendiceal stump. The patient was taken for laparoscopy and a 2 cm inflamed appendiceal stump was encountered. A distal caecectomy was performed and the patient made an unremarkable recovery. Histological examination was consistent with acute inflammation of the appendiceal stump. Only a small number of case reports of stump appendicitis have been published so far. Correct identification and ligation of the appendiceal stump is crucial to prevent this complication. Although normally it is treated with completion appendicectomy, the optimal treatment approach for this condition has not been well established.

Case Presentation: A 29-year-old male patient with urgent persistant bacteriuria and dysuria was referred to our clinic. Physical examination and blood tests were normal. He had used various antibiotics due to recurrent UTI for about 20 years. Computed tomography revealed the fistula tract between the distal end of the appendix and right lateral wall of the bladder dome. He was successfully treated with robot-assisted laparoscopic repair. Following this surgery, the patient's complaints were resolved completely. Conclusion: AVF is the rare condition. Robot-assisted laparoscopy repair of AVF is safe and effective treatment option.

    The Toy-Smoot laparoscopic hernioplasty has been performed on 75 patients with a total of 83 hernioplasties over the past 20 months. Sixty-nine patients were male and six were female. The age range was 20 to 75 years with an average age of 51.5 years. Twelve of the patients had bilateral hernias repaired: 55 direct hernias, 16 indirect hernias, and 5 pantaloon hernias. Eleven of the repairs were for recurrent hernias. The procedure was performed under general anesthesia. The abdomen was insufflated with carbon dioxide, establishing the pneumoperitoneum. Three 11 mm trocars were inserted, the first via the umbilicus, into which the 0 degrees endoscope was inserted. Two additional trocars were inserted at the level of the umbilicus at the anterior axillary lines. The hernia sacs were left in situ. The medial umbilical ligament was dissected medially, so as to identify directly the pubic tubercle and the Cooper's ligament. An expanded PTFE soft tissue patch, 1 mm thick and 7.5 x 10 cm in size, was attached to the Nanticoke Endo-patch spreader and introduced via the contralateral trocar and positioned over the hernia defect. The Endopath EMS stapler was then used to secure the PTFE patch over the hernia defect. This required secure anatomical fixation to the transversalis fascia anteriorly and laterally, the pubic tubercle, and the posterior rectus sheath, medially, Cooper's ligament, posteromedially, and the endoabdominal fascia, posterolaterally. There were a total of seven different complications, one major, which was a bladder injury that required an open repair of the bladder and then an open, conventional hernioplasty.(ABSTRACT TRUNCATED AT 250 WORDS)

    Minimally invasive therapy aims to minimize the trauma of any interventional process but still achieve a satisfactory therapeutic result. The development of "critical pathways," rapid mobilization and early feeding have contributed towards the goal of shorter hospital stay. This concept has been extended to include laparoscopic cholecystectomy and hernia repair. Reports have been published confirming the safety of same day discharge for the majority of patients. However, we would caution against overenthusiastic ambulatory laparoscopic cholecystectomy on the rational but unproven assumption that early discharge will lead to occasional delays in diagnosis and management of postoperative complications. Intraoperative complications of laparoscopic surgery are mostly due to traumatic injuries sustained during blind trocar insertion and physiologic changes associated with patient positioning and pneumoperitoneum creation. General anesthesia and controlled ventilation comprise the accepted anesthetic technique to reduce the increase in PaCO2. Investigators have recently documented the cardiorespiratory compromise associated with upper abdominal laparoscopic surgery, and particular emphasis is placed on careful perioperative monitoring of ASA III-IV patients during insufflation. Setting limits on the inflationary pressure is advised in these patients. Anesthesiologists must maintain a high index of suspicion for complications such as gas embolism, extraperitoneal insufflation and surgical emphysema, pneumothorax and pneumomediastinum. Postoperative nausea and vomiting are among the most common and distressing symptoms after laparoscopic surgery. A highly potent and selective 5-HT3 receptor antagonist, ondansetron, has proven to be an effective oral and IV prophylaxis against postoperative emesis in preliminary studies. Opioids remain an important component of the anesthesia technique, although the introduction of newer potent NSAIDs may diminish their use. A preoperative

    2016-01-01

    Background The urachus and the urachal remnants represent a failure in the obliteration of the allantois at birth that connects the bladder to the umbilicus. After birth it obliterates and presents as the midline umbilical ligament. Urachal cyst are the most common urachal anomaly in the pediatric population. The traditional surgical approach is a semicircular infraumbilical incision or a lower midline laparotomy. Methods In a 10 years period at Pediatric Surgery Department of Vicenza 16 children were diagnosed with urachal anomalies presenting as abdominal or urinary symptoms. Eight underwent open excision; eight were treated by laparoscopic surgery. The average age was 5.5 years (range, 4 months–13 years) in open group and 10 years (range, 1 month–18 years) in laparoscopic group. Results Mean operative time was 63 minutes (range, 35–105 minutes) in open group, 50 minutes (range, 35–90 minutes) in laparoscopic group. There were no postoperative complications. The patients of laparoscopic group were all discharged after few days (range, 2–4 days). Pathological examination confirmed a benign urachal remnant in all cases. Reporting our experience since comparing the two surgical approaches we want to describe the technique step by step of laparoscopic urachal cyst excision as minimally invasive diagnostic and surgical techniques. Conclusions Laparoscopy represents a useful alternative for the management of persistent or infected urachus, in particular when there’s the suspect despite the lack of radiological evidence. The morbidity associated with this approach is very low as the risk or recurrence. Laparoscopy in the management of urachal cyst is safe effective and ensures good cosmesis with all the advantages of minimally invasive approach. PMID:27867852

    Background and Objectives: Laparoscopy has acquired an unquestionable position in surgical practice as a diagnostic and operative tool. Recently, the laparoscopic approach has become a valuable option for adrenalectomy. This paper reports, in detail, our experience of laparoscopic adrenalectomy performed for adrenal tumors. Methods: We performed 12 laparoscopic adrenalectomies from October 29, 1997 to October 31, 1998. The technique of laparoscopic adrenalectomy is described thoroughly in all relevant details for either left or right-sided adrenal lesions. Results: The presented technique of laparoscopic adrenalectomy in all 12 cases provided good and relatively simple exposure of the immediate operative area. All relevant vascular elements were safely controlled, adrenal tumors could be successfully removed, and adequate hemostasis was achieved. No intraoperative or postoperative complications were observed. Conclusions: Laparoscopic adrenalectomy is a safe alternative to open surgery and is preferred for most patients because of shorter postoperative hospital stay and less postoperative discomfort.

    Laparoscopy has become a standard approach for adrenalectomy because of its safety, low invasiveness, and less demanding technical nature and the readily removable size of tumor through trocar incision. Comparative studies between open and laparoscopic adrenalectomy document less blood loss, shorter hospital stay, and lower incidence of complication. These reports also show that the patients have less pain, use fewer narcotics postoperatively, and have quicker resumption of oral intake after surgery with the laparoscopic approach. The techniques for laparoscopic adrenalectomy started with the transperitoneal approach and developed into the retroperitoneal approach. Further technical development and recognition yielded three transperitoneal and two retroperitoneal approaches. Characteristics of each approach are discussed. Due to technical developments and experiences in laparoscopic surgery, application of the laparoscopic approach has been expanded to include excision for adrenal cancer and laparoscopic partial adrenalectomy for bilateral pheochromocytoma in certain cases and in selected institutes.

    In response to the increasing interest in minimally invasive surgery by both patients and surgeons, most abdominal surgery today is carried out laparoscopically. Laparoscopic splenectomy has become a gold standard in the treatment of spleen disorders related to hematologic diseases. Increasing laparoscopic surgery experience and improved new vessel sealing equipment have led to a decreasing number of ports in laparoscopic surgery and to operations from 1 incision. We carried out single-incision double-port laparoscopic splenectomy in a patient with immune thrombocytopenic purpura using only 2 trocars with a simple manipulation. Our review of the related literature revealed no earlier description of a single-incision double-port laparoscopic splenectomy. We therefore present herein this earlier unreported technique.

    Laparoscopic Loop colostomy has been described in the literature as a safe and useful minimally invasive technique. It is indicated in patients with large perineal wounds requiring fecal diversion, obstructing lesions of the distal colon or rectum. The purpose of this article is to describe a modified version of this procedure which was used by 1 surgeon in our institution on a series of 5 patients. In this method, an esophageal retractor and Penrose drain are used to tent up and exteriorize the desired segment of colon to be used for the colostomy site. Results were that all 5 were completed laparoscopically and there were no complications. In conclusion, this variation in the technique has been useful in our institution and others may find it worthwhile to consider.

    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.

    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

  11. Distal esophageal spasm: an update.

    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.

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

    Laparoscopic hepatectomy is a standard surgical procedure. However, it is difficult to perform in patients with severe cirrhosis because of fibrosis and a high risk of hemorrhage. We report our recent experience in five cases of pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver in patients with severe cirrhosis. From 2012 to 2014, we performed pure laparoscopic partial hepatectomy in five patients with severe liver cirrhosis (indocyanine green retention rate at 15 min [ICG R15] >30% and fibrosis stage f4). A pure laparoscopic Pringle maneuver was employed in all patients. We investigated operative time, blood loss, duration of hospitalization and the days when discharge was possible, and compared these findings with those of patients with a normal liver (ICG R15 <10%, f0) who underwent pure laparoscopic partial hepatectomy during the same period (n = 7). As a result, operative time, blood loss, duration of hospitalization and the days when discharge was possible were similar in patients with cirrhosis undergoing pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver to those in patients with a normal liver undergoing pure laparoscopic partial hepatectomy. In conclusion, pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver appears to be safe in patients with severe cirrhosis.

    Spigelian hernia (SH) is an uncommon abdominal wall hernia. Its clinical symptoms are not characteristic, and the preoperative diagnosis is often difficult because SH can simulate the symptoms of more classical lower quadrant abdominal diseases. We report a case of SH in an 80-year-old woman that was complicated by incarceration and diagnosed by physical examination and ultrasound. At the time of presentation, she had an abdominal mass that was soft and occasionally painful, and aggravated by movements that increase intraabdominal pressure. Laparoscopic examination of the abdominal cavity identified the incarcerate jejunum ansae. The defect was a large opening in the peritoneum along the lateral margin of the rectus abdominis muscle. After dissection of the intestinal adhesions, a prosthetic polypropylene mesh was introduced and fixed with staples into the lateral abdominal wall. There were no postoperative complications. We conclude that the laparoscopic approach is a feasible alternative to the conventional open technique that is easy, safe, and allows excellent operative visualization.

    Background and Objectives: The mobile cecum is an embryologic abnormality and has been associated with functional colon disease (chronic constipation and irritable bowel syndrome). However, unlike functional disease, the primary treatment is operative, using laparoscopic cecopexy. We compare the epidemiology and pathophysiology of mobile cecum syndrome and functional colon disease and propose diagnostic and treatment guidelines. Method: This study was a case–control series of 15 patients who underwent laparoscopic cecopexy. Age, gender, recurrent abdominal pain, and constipation based on Rome III criteria were assessed. Ileocecal–appendiceal unit displacement was graded as follows: I (cecum retroperitoneal or with little mobility); II (wide mobility, crossing the midline); and III (maximum mobility, reaching the left abdomen). Patients with Grades II and III underwent laparoscopic cecopexy. The clinical outcomes were evaluated according to modified Visick's criteria, and postoperative complications were assessed according to the Clavien-Dindo classification. Results: The mean age was 31.86 ± 12.02 years, and 13 patients (86.7%) were women. Symptoms of constipation and abdominal pain were present in 14 (93.3%) and 11 (73.3%), respectively. Computed tomography was performed in 8 (53.3%) patients. The mean operative time was 41 ± 6.66 min. There were no postoperative infections. One (7.8%) patient was classified as Clavien Dindo IIIb and all patients were classified as Visick 1 or 2. Conclusion: Many patients with clinical and epidemiological features of functional colon disease in common in fact have an anatomic anomaly, for which the treatment of choice is laparoscopic cecopexy. New protocols should be developed to support this recommendation. PMID:27807396

    Cholangiography does not prevent bile duct injury, but if performed properly, it can identify impending injury before hand. We present a modified form of laparoscopic cholecystcholangiography; only 5 min are required to perform this technique. Some 408 consecutive peroperative cholangiographies are analyzed. We recommend this method, which decreases the risk of bile duct injuries, reveals occult bile duct stones in 4.2%, and gives the opportunity to approximate the gold standard of cholecystectomies.

    Laparoscopic Roux-en-Y bypass is being increasingly used for weight reduction in patients with morbid obesity. Unfortunately, some complications can occur after this procedure, the most frequent being intestinal obstruction (due to stenosis of the anastomosis at the distal end of the loop, internal hernias, bands, and adhesions), anastomotic leaks, and bleeding. This article provides basic knowledge about the surgical technique and its correlation with the common postoperative changes with the aim of facilitating the interpretation of CT findings and the identification of postoperative complications in these patients.

  19. Review. Laparoscopic appendicectomy: current status.

    PubMed Central

    Memon, M. A.

    1997-01-01

    Laparoscopic appendicectomy (LA), has failed to gain unequivocal acceptance by the general surgical community as an alternative to open appendicectomy (OA). This is because the early postoperative recovery leading to quicker hospital discharge, which led to the worldwide acceptance of laparoscopic cholecystectomy, has not been universally seen with LA. Moreover, in the majority of the published series of LAs, there seems to be a trend towards an increased incidence of intra-abdominal abscesses. However, laparoscopy is superior to the 'watch and wait' policy where the diagnosis of appendicitis is questionable. Furthermore, since a large incision can be avoided by using the LA technique in obese patients, the incidence of postoperative morbidity can be reduced considerably. Nevertheless, before endorsing routine and widespread use of LA, it is essential that this technique is critically evaluated in well-designed, controlled, randomised trials, showing clearly the major benefits to the patient in terms of quicker hospital discharge, reduced postoperative pain, decreased wound infection and early return to full activities. Laparoscopic appendicectomy will never replace all open appendicectomies, but should become an alternative in certain groups of patients. PMID:9422862

    Introduction Pectopexy, a laparoscopic method for prolapse surgery, showed promising results in recent literature. Further improving this approach by reducing surgical time may decrease complication rates and patient morbidity. Since laparoscopic suturing is a time consuming task, we propose a single suture /mesh ileo-pectineal ligament fixation as opposed to the commonly used continues approach. Methods Evaluation was performed on human non-embalmed, fresh cadaver pelves. A total of 33 trials was performed. Eight female pelves with an average age of 75, were used. This resulted in 16 available ligaments. Recorded parameters were ultimate load, displacement at failure and stiffness. Results The ultimate load for the mesh + simplified single “interrupted” suture (MIS) group was 35 (± 12) N and 48 (± 7) N for the mesh + continuous suture (MCS) group. There was no significant difference in the ultimate load between both groups (p> 0.05). This was also true for displacement at failure measured at 37 (± 12) mm and 36 (±5) mm respectively. There was also no significant difference in stiffness and failure modes. Conclusion Given the data above we must conclude that a continuous suture is not necessary in laparoscopic mesh / ileo-pectineal ligament fixation during pectopexy. Ultimate load and displacement at failure results clearly indicate that a single suture is not inferior to a continuous approach. The use of two single sutures may improve ligamental fixation. However, overall stability should not benefit since the surgical mesh remains the limiting factor. PMID:26844890

    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.

    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.

    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

    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.

    Introduction Type 2 diabetes (T2D) in association with obesity is an increasing disease burden. Bariatric surgery is the only effective therapy for achieving remission of T2D among those with morbid obesity. It is unclear which of the two most commonly performed types of bariatric surgery, laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB), is most effective for obese patients with T2D. The primary objective of this study is to determine whether LSG or LRYGB is more effective in achieving HbA1c<6% (<42 mmol/mol) without the use of diabetes medication at 5 years. Methods and analysis Single-centre, double-blind (assessor and patient), parallel, randomised clinical trial (RCT) conducted in New Zealand, targeting 106 patients. Eligibility criteria include age 20–55 years, T2D of at least 6 months duration and body mass index 35–65 kg/m2 for at least 5 years. Randomisation 1:1 to LSG or LRYGB, used random number codes disclosed to the operating surgeon after induction of anaesthesia. A standard medication adjustment schedule will be used during postoperative metabolic assessments. Secondary outcomes include proportions achieving HbA1c<5.7% (39 mmol/mol) or HbA1c<6.5% (48 mmol/mol) without the use of diabetes medication, comparative weight loss, obesity-related comorbidity, operative complications, revision rate, mortality, quality of life, anxiety and depression scores. Exploratory outcomes include changes in satiety, gut hormone and gut microbiota to gain underlying mechanistic insights into T2D remission. Ethics and dissemination Ethics approval was obtained from the New Zealand regional ethics committee (NZ93405) who also provided independent safety monitoring of the trial. Study commenced in September 2011. Recruitment completed in October 2014. Data collection is ongoing. Results will be reported in manuscripts submitted to peer-reviewed journals and in presentations at national and international meetings

    To evaluate the role of ALA induced fluorescence diagnosis in laparoscopic surgery, we induced peritoneal carcinosis in rats by multilocular intraabdominal tumorcell implantation (CC531). The animals were photosensitized by intraabdominal ALA lavage. Laparoscopy was performed with both, conventional white and then blue light (D-Light, KARL STORZ Germany) excitation. Laparoscopy with conventional white light showed peritoneal carcinoma foci from 0.1 to 2 cm in diameter. All macroscopically visible tumors (n equals 142) were fluorescence positive after laparoscopic blue light excitation. In addition, 30 laparoscopic not visible (white light) tumors showed fluorescence and were histologically confirmed as colon carcinoma metastases. We conclude that only ALA induced laparoscopic fluorescence detection after blue light excitation is the adequate method to detect the entire extent of the intraabdominal tumor spread. Fluorescence laparoscopy is essential for laparoscopic staging of colorectal cancer because of a higher rate of cancer foci detection.

    AIM: To structure the rate of intraoperative complications that requires an intraoperative or perioperative resolution. METHODS: We perform a literature review of Medline database. The research was focused on intraoperative laparoscopic procedures inside the field of urological oncology. General rate of perioperative complications in laparoscopic urologic surgery is described to be around 12.4%. Most of the manuscripts published do not make differences between pure intraoperative, intraoperative with postoperative consequences and postoperative complications. RESULTS: We expose a narrative statement of complications, possible solutions and possible preventions for most frequent retroperitoneal and pelvic laparoscopic surgery. We expose the results with the following order: retroperitoneal laparoscopic surgery (radical nephrectomy, partial nephrectomy, nephroureterectomy and adrenalectomy) and pelvic laparoscopic surgery (radical prostatectomy and radical cystectomy). CONCLUSION: Intraoperative complications vary from different series. More scheduled reports should be done in order to better understand the real rates of complications. PMID:25984519

Methods: From March 1997 to October 1998, 22 patients with a diagnosis of acute abdominal gynecologic emergencies underwent laparoscopic intervention. A transvaginal ultrasound was performed on all patients preoperatively to supplement the diagnostic workup. Surgical time, complications, and length of hospital stay were evaluated, and the laparoscopic diagnosis was compared with the preoperative diagnosis. Results: The laparoscopic diagnosis was different from the preoperative diagnosis in 31.8% of patients. Of the 22 patients, laparoscopic therapeutic procedures were performed in 18 (81.8%), all satisfactorily, and with no need for conversion to open surgery. No morbidity or mortality occurred. Conclusion: Laparoscopy is a safe and effective method for diagnosing and treating gynecologic emergencies. PMID:14558712

    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.

    Purpose The ideal treatment for choledocholithiasis should be simple, readily available, reliable, minimally invasive and cost-effective for patients. We performed this study to compare the benefits and drawbacks of different laparoscopic approaches (transcystic and choledochotomy) for removal of common bile duct stones. Methods A systematic search was implemented for relevant literature using Cochrane, PubMed, Ovid Medline, EMBASE and Wanfang databases. Both the fixed-effects and random-effects models were used to calculate the odds ratio (OR) or the mean difference (MD) with 95% confidence interval (CI) for this study. Results The meta-analysis included 18 trials involving 2,782 patients. There were no statistically significant differences between laparoscopic choledochotomy for common bile duct exploration (LCCBDE) (n = 1,222) and laparoscopic transcystic common bile duct exploration (LTCBDE) (n = 1,560) regarding stone clearance (OR 0.73, 95% CI 0.50–1.07; P = 0.11), conversion to other procedures (OR 0.62, 95% CI 0.21–1.79; P = 0.38), total morbidity (OR 1.65, 95% CI 0.92–2.96; P = 0.09), operative time (MD 12.34, 95% CI −0.10–24.78; P = 0.05), and blood loss (MD 1.95, 95% CI −9.56–13.46; P = 0.74). However, the LTCBDE group showed significantly better results for biliary morbidity (OR 4.25, 95% CI 2.30–7.85; P<0.001), hospital stay (MD 2.52, 95% CI 1.29–3.75; P<0.001), and hospital expenses (MD 0.30, 95% CI 0.23–0.37; P<0.001) than the LCCBDE group. Conclusions LTCBDE is safer than LCCBDE, and is the ideal treatment for common bile duct stones. PMID:27668730

    Postoperative pancreatic fistula (POPF) is the most frequent and serious complication after distal pancreatectomy (DP) and often leads to other postoperative complications. Numerous studies have been conducted to clarify the risk factors for POPF after DP, and to also determine effective prophylactic treatments. In this article, we review the current evidence on the risk factors for POPF after DP, and also provide new evidence to support the currently implemented prophylactic measures against POPF after DP. The patient-related and surgery-related risk factors and risk factors specific to staplers are discussed. Several studies have suggested that a thick pancreas is a risk factor for POPF using a stapler and that a higher stapler height or pancreatoenteric anastomosis might be useful for preventing POPF when transecting a thick pancreas. Various methods, such as stapler closure, procedures that may be performed in addition to stapler closure, pancreatoenteric anastomosis, pancreatic transection devices, laparoscopic surgery, pancreatic stenting, stump coverage, and somatostatin analogs, have been tested and in comparison with conventional procedures in case-control studies and randomized, controlled trials. Although some studies have shown the superiority of these methods to the conventional procedures, a consensus on precautionary measures that can be taken against POPF remains to be established. Further investigation is necessary to develop a reliable strategy for preventing POPF and to improve the outcomes of patients after DP.

    Background Laparoscopic liver surgery is becoming increasingly common. This cohort study was designed to directly compare perioperative outcomes of the left lateral segmentectomy via laparoscopic and open approach. Methods Between 2002 and 2006 43 left lateral segmentectomies were performed at King's College Hospital. Those excluded from analysis included previous liver resections, polycystic liver disease, liver cirrhosis and synchronous operations. Of 20 patients analysed, laparoscopic (n = 10) were compared with open left lateral segmentectomy (n = 10). Both groups had similar patient characteristics. Results Morbidity rates were similar with no wound or chest infection in either group. The conversion rate was 10% (1/10). There was no difference in operating time between the groups (median time 220 minutes versus 179 minutes, p = 0.315). Surgical margins for all lesions were clear. Less postoperative opiate analgesics were required in the laparoscopic group (median 2 days versus 5 days, p = 0.005). The median postoperative in-hospital stay was less in the laparoscopic group (6 days vs 9 days, p = 0.005). There was no mortality. Conclusion Laparoscopic left lateral segmentectomy is safe and feasible. Laparoscopic patients may benefit from requiring less postoperative opiate analgesia and a shorter post-operative in-hospital stay. PMID:19735573

    Short bowel syndrome (SBS) is a potential postoperative complication after intra-abdominal procedures. Whether the laparoscopic approach is as likely to result in SBS or the causative mechanisms are similar to open procedures is unknown. Our aim was to evaluate potential mechanisms of SBS after laparoscopic procedures. The records of 175 adult patients developing SBS as a postoperative complication were reviewed. One hundred forty-seven patients had open procedures and 28 laparoscopic. Colectomy (39%), hysterectomy (11%), and appendectomy (11%) were the most common open procedures. SBS followed laparoscopic gastric bypass (46%) and cholecystectomy (32%) most frequently. The mechanisms of SBS were different: adhesive obstruction (57 vs 22%, P < 0.05) was more common in the open group, whereas volvulus (18 vs 46%, P < 0.05) was more common after laparoscopy. Overall, ischemia (25 vs 32%) was similar but significantly more laparoscopic patients had postoperative hypoperfusion (32 vs 67%, P < 0.05). Eleven of the 13 laparoscopic bariatric procedures had internal hernias and volvulus. Of the nine patients undergoing cholecystectomy, four developed ischemia early postoperatively presumably secondary to pneumoperitoneum. SBS is an increasingly recognized complication of laparoscopic procedures. The mechanisms of intestinal injury differ from open procedures with a higher incidence of volvulus and more frequent ischemia from hypoperfusion.

    An improved technique for laparoscopic appendectomy based on an experience of > 120 cases is presented. This method includes numerous additions to and modifications of previously described techniques and is effective for gangrenous and perforated appendicitis as well as for less severe cases. The most important elements are that (a) it is a safer procedure for attaining insertion of the Veress needle and the primary trocar; (b) it employs electrocautery to separate the appendix from the mesoappendix; (c) an Endosac can be used for removal of the appendix from the abdomen without contamination of the abdominal wall; (d) no laser is necessary; and (e) staples are rarely necessary.

  18. Distal realignment (tibial tuberosity transfer).

    2012-09-01

    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.

    Introduction The role of shunt placement is to divert cerebrospinal fluid from within the ventricles to an alternative location in the setting of hydrocephalus. One of the rare shunt complications is distal catheter migration, and various body sites have been reported, including the scrotum. Although cases of scrotal migration of distal catheter have been reported in pediatric patients, cases in adult patients are rare due to obliterated processus vaginalis. Furthermore, there has not been a case reported for scrotal migration in an adult at an early onset. Presentation of case 65-year-old male underwent shunt placement for normal-pressure hydrocephalus-like symptoms. On post-operative day seven patient developed right testicular edema, for which ultrasound was performed, revealing hydrocele along with the presence of distal catheter in the scrotum. On post-operative day nine patient underwent distal catheter trimming via laparoscopic approach with general surgery, with post-operative imaging showing satisfactory location of distal catheter in the peritoneal cavity. Discussion/Conclusion Early onset of distal catheter migration into scrotum in an adult male is a unique case, as most cases are reported in pediatric patients, and it is the first case reported in the English literature to have occurrence at an early onset during the peri-operative period. As our case demonstrates, early occurrence and detection of scrotal migration of the distal catheter prevent shunt malfunction. Prompt surgical management of catheter repositioning is therefore recommended to avoid the risk of further complications. PMID:25553524

    Splenic arteriovenous fistulas (SAVFs) with splenic vein aneurysms are extremely rare entities. There have been no prior reports of SAVFs developing after laparoscopic pancreatectomy. Here, we report the first case. A 40-year-old man underwent a laparoscopic, spleen-preserving, distal pancreatectomy for an endocrine neoplasm of the pancreatic tail. Three months after surgery, a computed tomography (CT) scan demonstrated an SAVF with a dilated splenic vein. The SAVF, together with the splenic vein aneurysm, was successfully treated using percutaneous transarterial coil embolization of the splenic artery, including the SAVF and drainage vein. After the endovascular treatment, the patient's recovery was uneventful. He was discharged on postoperative day 6 and continues to be well 3 mo after discharge. An abdominal CT scan performed at his 3-mo follow-up demonstrated complete thrombosis of the splenic vein aneurysm, which had decreased to a 40 mm diameter. This is the first reported case of SAVF following a laparoscopic pancreatectomy and demonstrates the usefulness of endovascular treatment for this type of complication.

    In our initial experience with 82 patients, laparoscopic cholecystectomy has shown numerous advantages over open cholecystectomy. Both intraoperative blood loss and postoperative need for pain medication have been minimal. Most patients were discharged within 24 to 36 hours and resumed normal activities within 3 to 5 days. The aesthetic aspect is also an obvious advantage, since the laparoscopic procedure avoids disfiguring abdominal scars. Previous abdominal surgery is not a contraindication to attempting this procedure. Based on our experience, laparoscopic cholecystectomy can be done safely on most patients who are candidates for open cholecystectomy, including the elderly, the obese, and those with acute gangrenous cholecystitis.

    Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior epigastric arteries or a direct tear of the rectus muscle. As far as we are aware this complication has not been reported after laparoscopic appendicectomy. PMID:21124654

    Background Laparoscopic cholecystectomy has traditionally been performed with four incisions to insert four trocars, in a simple, efficient and safe way. Aim To describe a simplified technique of laparoscopic cholecystectomy with two incisions, using basic conventional instrumental. Technique In one incision in the umbilicus are applied two trocars and in epigastrium one more. The use of two trocars on the same incision, working in "x" does not hinder the procedure and does not require special instruments. Conclusion Simplified laparoscopic cholecystectomy with two incisions is feasible and easy to perform, allowing to operate with ergonomy and safety, with good cosmetic result. PMID:25004296

    Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. Ongoing refinement of the surgical technique and instrumentation is likely to expand its role in gynecologic surgery in the future. We perform single-incision total laparoscopic hysterectomy using three ports in the single transumbilical incision.

    2014-01-01

    Background and Objectives: Robotic surgery has been advocated for the radical excision of rectal cancer. Most data supporting its use have been reported from European and Asian centers, with a paucity of data from the United States documenting clear advantages of the robotic technique. This study compares the short-term outcome of robotic versus laparoscopic surgery. Methods: Consecutive patients who underwent laparoscopic (group 1) or robotic (group 2) rectal cancer excision at a single institution over a 2-year period were retrospectively reviewed. The main outcome measures were operative time, blood loss, conversion rates, number of lymph nodes, margin positivity, length of hospital stay, complications, and readmission rates. Results: Forty-two patients were analyzed. The median operative time was shorter in group 1 than that in group 2 (240 minutes vs 260 minutes, P = .04). No difference was noted in blood loss, transfusion rates, intraoperative complications, or conversion rates. There was no difference in circumferential or distal margin positivity. The median length of stay was shorter in group 1 (5 days vs 6 days, P = .05). The 90-day complication rate was similar in both groups (33% vs 43%, P = .75), but there was a trend toward more anastomotic leaks in group 1 (14% vs 0%, P = .23). Similarly, a non–statistically significant trend toward a higher readmission rate was noted in group 1 (24% vs 5%, P = .18). Conclusion: Robotic rectal cancer excision yielded a longer operative time and hospital length of stay, although immediate oncologic results were comparable. The need for randomized data is critical to determine whether the added resource utilization in robotic surgery is justifiable. PMID:25392653

    We describe in this paper a training system for minimally invasive surgery (MIS) that creates an immersive training simulation by recording the pathways of the instruments from an expert surgeon while performing an actual training task. Instrument spatial pathway data is stored and later accessed at the training station in order to visualize the ergonomic experience of the expert surgeon and trainees. Our system is based on tracking the spatial position and orientation of the instruments on the console for both the expert surgeon and the trainee. The technology is the result of recent developments in miniaturized position sensors that can be integrated seamlessly into the MIS instruments without compromising functionality. In order to continuously monitor the positions of laparoscopic tool tips, DC magnetic tracking sensors are used. A hardware-software interface transforms the coordinate data points into instrument pathways, while an intuitive graphic user interface displays the instruments spatial position and orientation for the mentor/trainee, and endoscopic video information. These data are recorded and saved in a database for subsequent immersive training and training performance analysis. We use two 6 DOF DC magnetic trackers with a sensor diameter of just 1.3 mm - small enough for insertion into 4 French catheters, embedded in the shaft of a endoscopic grasper and a needle driver. One sensor is located at the distal end of the shaft while the second sensor is located at the proximal end of the shaft. The placement of these sensors does not impede the functionally of the instrument. Since the sensors are located inside the shaft there are no sealing issues between the valve of the trocar and the instrument. We devised a peg transfer training task in accordance to validated training procedures, and tested our system on its ability to differentiate between the expert surgeon and the novices, based on a set of performance metrics. These performance metrics

    Background and Objectives: To analyze the frequency of complications during laparoscopic gynecologic surgery and identify associated risk factors. Methods: A descriptive observational study was performed between January 2000 and December 2012 and included all gynecologic laparoscopies performed at our center. Variables were recorded for patient characteristics, indication for surgery, length of hospital stay (in days), major and minor complications, and conversions to laparotomy. To identify risk factors and variables associated with complications, crude and adjusted odds ratios were calculated with unconditional logistic regression. Results: Of all 2888 laparoscopies included, most were procedures of moderate difficulty (adnexal surgery) (54.2%). The overall frequency of major complications was 1.93%, and that of minor complications was 4.29%. The level of technical difficulty and existence of prior abdominal surgery were associated with a higher risk of major complications and conversions to laparotomy. Conclusion: Laparoscopic gynecologic surgery is associated with a low frequency of complications but is a procedure that is not without risk. Greater technical difficulty and prior surgery were factors associated with a higher frequency of complications. PMID:25392659

    2013-01-01

    A best evidence topic in surgery was written according to a structured protocol. The question addressed was whether playing video games improves surgical performance in laparoscopic procedures. Altogether 142 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. The details of the papers were tabulated including relevant outcomes and study weaknesses. We conclude that medical students and experienced laparoscopic surgeons with ongoing video game experience have superior laparoscopic skills for simulated tasks in terms of time to completion, improved efficiency and fewer errors when compared to non-gaming counterparts. There is some evidence that this may be due to better psycho-motor skills in gamers, however further research would be useful to demonstrate whether there is a direct transfer of skills from laparoscopic simulators to the operating table.

    Only a few studies have revealed using laparoscopic technique with limited resection of gastrointestinal stromal tumour (GIST) of the duodenum. A 68-year-old man was admitted to the hospital due to upper gastrointestinal (GI) bleeding. Evaluation revealed an ulcerated, bleeding GI tumour in the second part of the duodenum. After control of bleeding during gastroduodenoscopy, he underwent a laparoscopic wedge resection of the area. During 1.5 years of follow-up, the patient is disease free, eats drinks well, and has regained weight. Surgical resection of duodenal GIST with free margins is the main treatment of this tumour. Various surgical treatment options have been reported. Laparoscopic resection of duodenal GIST is an advanced and challenging procedure requiring experience and good surgical technique. The laparoscopic limited resection of duodenal GIST is feasible and safe, reducing postoperative morbidity without compromising oncologic results. PMID:28281485

    Although laparoscopic surgery accounts for >2 million surgical procedures every year, the current preoperative risk scores and guidelines do not adequately assess the risks of laparoscopy. In general, laparoscopic procedures have a lower risk of morbidity and mortality compared with operations requiring a midline laparotomy. During laparoscopic surgery, carbon dioxide insufflation may produce significant hemodynamic and ventilatory consequences such as increased intraabdominal pressure and hypercarbia. Hemodynamic insults secondary to increased intraabdominal pressure include increased afterload and preload and decreased cardiac output, whereas ventilatory consequences include increased airway pressures, hypercarbia, and decreased pulmonary compliance. Hemodynamic effects are accentuated in patients with cardiovascular disease such as congestive heart failure, ischemic heart disease, valvular heart disease, pulmonary hypertension, and congenital heart disease. Prevention of cardiovascular complications may be accomplished through a sound understanding of the hemodynamic and physiological consequences of laparoscopic surgery as well as a defined operative plan generated by a multidisciplinary team involving the preoperative consultant, anesthesiologist, and surgeon.

    AIM: To assess the feasibility, safety of rigid tubal ligation scope in laparoscopic common bile duct (CBD) exploration. MATERIALS AND METHODS: Rigid nephroscope was used for laparoscopic CBD exploration until one day we tried the same with the rigid tubal ligation scope, which was passed easily into CBD both proximally and distally visualising the interior of the duct for presence of stone that were removed using endoscopic retrograde cholangiopancreaticography (ERCP) basket. This serendipity led us to use this scope for numerous patients from then on. A total of 62 patients, including male and female, underwent laparoscopic CBD exploration after choledochotomy with rigid tubal ligation scope between March 2007 and December 2012 followed by cholecystectomy. All the patients had both cholelithiasis and choledocholithiasis with minimum duct diameter of 12 mm. A total of 48 patients were given T-tube through choledochotomy and closed, and the remaining 14 patients had primary closure of choledochotomy. RESULTS: There were no intra-operative complications in any of the patients like CBD injury or portal vein injury. Post-operatively graded clamping of T-tube was done and was removed after 15 days in the patients who were given T-tube. None had retained the stone after T-tube cholangiography, which was done before removing the tube. Mean duration of follow up was 6 months. No patients had any complaints during the follow up. CONCLUSION: Laparoscopic CBD exploration is also feasible with rigid tubal ligation scope. With experienced surgeons, CBD injury is very minimal and stone clearance can be achieved in almost all patients. This rigid tubal ligation scope can be an alternative to other rigid and flexible scopes. PMID:24761081

    Emphysematous cholecystitis (EC) is an uncommon variant of acute cholecystitis, which is caused by secondary infection of the gallbladder wall with gas-forming organisms. The mortality rate of EC is still as high as 25%. Emergency surgical intervention is indicated. Open cholecystectomy has been traditionally accepted as a standard treatment for EC. We present a case of EC successfully treated by laparoscopic surgery. Laparoscopic cholecystectomy for EC is considered to be safe and effective when indicated. PMID:24876461

    Gallstone ileus is an uncommon cause of small bowel obstruction, occurring when one or more large gallstones erode through the gallbladder and into the intestinal lumen. The presentation is often nonspecific with intermittent symptoms, confounding diagnosis, and delaying treatment. The traditional treatment is through open enterolithotomy. Thus far only 30 of over 400 case reports on MEDLINE describe laparoscopic enterolithotomy. In this article we describe a successful total laparoscopic approach to the treatment of gallstone ileus.

    Intestinal and urinary tract involvement by endometriosis may be symptomatic, particularly when invasive disease is present. Even in expert hands, complete excision of all invasive disease cannot be accomplished laparoscopically in every case. The practitioner must balance enthusiasm for the advantages of a laparoscopic approach with limitations of time and skill. Laparoscopy should be abandoned in a particular case if a better job can be performed by laparotomy. Hysterectomy with castration may not relieve symptoms due to invasive disease.

    Background: Clinical trials comparing laparoscopic gastrectomy (LG) versus traditional open gastrectomy (OG) have been planned, their surgical outcomes reported but their oncologic outcomes are still pending. Consequently, we have conducted this large-scale historical cohort study to provide relevant information rapidly to guide our current practice. Methods: Through a consensus meeting involving surgeons, biostatisticians, and epidemiologists, 30 variables of preoperative information possibly influencing surgeons’ choice between LG versus OG and potentially associating with outcomes were identified to enable rigorous estimation of propensity scores. A total of 4235 consecutive patients who underwent gastrectomy for gastric adenocarcinoma were identified and their relevant data were gathered from the participating hospitals. After propensity score matching, 1848 patients (924 each for LG and OG) were selected for comparison of long-term outcomes. Results: In the propensity-matched population, the 5-year overall survival was 96.3% [95% confidence interval (CI) 95.0–97.6] in the OG as compared with 97.1% (95% CI, 95.9–98.3) in LG. The number of all-cause death was 33/924 in the OG and 24/924 in the LG through the entire period, and the hazard ratio (LG/OG) for overall death was 0.75 (95% CI, 0.44–1.27; P = 0.290). The 3-year recurrence-free survival was 97.4% (95% CI, 96.4–98.5) in the OG and 97.7% (95% CI, 96.5–98.8) in the LG. The number of recurrence was 22/924 in the OG and 21/924 in the LG through the entire period, and the hazard ratio was 1.01 (95% CI, 0.55–1.84; P = 0.981). Conclusions: This observational study adjusted for all-known confounding factors seems to provide strong enough evidence to suggest that LG is oncologically comparable to OG for gastric cancer.

    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.

    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.

    Cholecystectomies and hernioplasties are the two most frequently performed surgical interventions. The laparoscopic technique can be offered for the simultaneous treatment with both operating indications. The synchronical operation can give all the advantages of the minimally invasive technique. Authors had performed laparoscopic cholecystectomy with laparoscopic hernioplasty in five cases. Two inguinal and three postoperative hernias were reconstructed. The cholecystectomy was performed with a "three punction method", and the hernioplasty by using the same approach, completed by inserting a fourth assisting trocar as required. The hernial ring was covered with an intraperitoneally placed mesh, which was fixed by staplers (the so-called "IPOM-method": intraperitoneal on-lay mesh). There was no intra-, nor postoperative complication. The hernioplasty combined with laparoscopic cholecystectomy did not have effect on postoperative pain and nursing time. The return to the normal physical activity was short, similar to laparoscopic hernioplasty (in 1-2 weeks). Authors conclude that the simultaneous, synchronous laparoscopic cholecystectomy and hernioplasty is recommended and should be the method of choice because it is more advantageous for patients.

    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.

    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

    With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC.

    Introduction Cholecystocolic fistula is a rare complication of gallbladder disease. Its clinical presentation is variable and nonspecific, and the diagnosis is made, mostly, incidentally during intraoperative maneuver. Cholecystectomy with closure of the fistula is considered the treatment of choice for the condition, with an increasingly reproducible tendency to the use of laparoscopy. Aim To describe the laparoscopic approach for cholecystocolic fistula and ratify its feasibility even with the unavailability of more specific instruments. Technique After dissection of the communication and section of the gallbladder fundus, the fistula is externalized by an appropriate trocar and sutured manually. Colonic segment is reintroduced into the cavity and cholecystectomy is performed avoiding the conversion procedure to open surgery. Conclusion Laparoscopy for resolution of cholecystocolic fistula isn't only feasible, but also offers a shorter stay at hospital and a milder postoperative period when compared to laparotomy.

    Gallstone ileus represents a rare complication (0,3-0,5%) of a serious, but common disease-gallstones, which affect around 10% of the population in the USA and Western Europe. Associated diseases (usually severe), elderly patients, delayed diagnosis and therapy due to late presentation to the hospital, account for the morbidity and mortality rates described in literature. We present the case of a patient with partial colon obstruction due to a large gallstone that was "lost" during an emergency laparoscopic cholecystectomy. The calculus eroded the intestinal wall, partially occluding the lumen, triggering recurrent Kerwsky-like, subocclusive episodes. The intraperitoneal abscess has spontaneously drained through the subhepatic drain and once the tube has been removed, a persistent intermittent fistula became obvious.

    To report our experience of pure laparoscopic and robot-assisted laparoscopic reconstructive surgery in congenital megaureter, seven patients (one bilateral) with symptomatic congenital megaureter underwent pure laparoscopic or robot-assisted laparoscopic surgery. The megaureter was exposed at the level of the blood vessel and was isolated to the bladder narrow area. Extreme ureter trim and submucosal tunnel encapsulation or papillary implantations and anti-reflux ureter bladder anastomosis were performed intraperitoneally by pure laparoscopic or robot-assisted laparoscopic surgery. The clinical data of seven patients after operation were analyzed, including the operation time, intraoperative complications, intraoperative bleeding volumes, postoperative complications, postoperative hospitalization time and pathological results. All of the patients were followed. The operation was successfully performed in seven patients. The mean operation times for pure laparoscopic surgery and robotic-assistant laparoscopic surgery were 175 (range: 150-220) and 187 (range: 170-205) min, respectively, and the mean operative blood loss volumes were 20 (range: 10-30) and 28.75 (range: 15-20) ml, respectively. There were no intraoperative complications. The postoperative drainage time was 5 (range: 4-6) and 5.75 (range: 5-6) d, respectively, and the indwelling catheter time was 6.33 (range: 4-8) d and 7 (range: 7-7) d, respectively. The postoperative hospitalization time was 7.67 (range: 7-8) d and 8 (range: 7-10) d, respectively. There was no obvious pain, no secondary bleeding and no urine leakage after the operation. Postoperative pathology reports revealed chronic urothelial mucosa inflammation. The follow-up results confirmed that all patients were relieved of their symptoms. Both pure laparoscopic and robot-assisted laparoscopic surgery using different anti-reflux ureter bladder anastomoses are safe and effective approaches in the minimally invasive treatment of congenital

    IMPORTANCE Evidence about the efficacy of laparoscopic resection of rectal cancer is incomplete, particularly for patients with more advanced-stage disease. OBJECTIVE To determine whether laparoscopic resection is noninferior to open resection, as determined by gross pathologic and histologic evaluation of the resected proctectomy specimen. DESIGN, SETTING, AND PARTICIPANTS A multicenter, balanced, noninferiority, randomized trial enrolled patients between October 2008 and September 2013. The trial was conducted by credentialed surgeons from 35 institutions in the United States and Canada. A total of 486 patients with clinical stage II or III rectal cancer within 12 cm of the anal verge were randomized after completion of neoadjuvant therapy to laparoscopic or open resection. INTERVENTIONS Standard laparoscopic and open approaches were performed by the credentialed surgeons. MAIN OUTCOMES AND MEASURES The primary outcome assessing efficacy was a composite of circumferential radial margin greater than 1 mm, distal margin without tumor, and completeness of total mesorectal excision. A 6%noninferiority margin was chosen according to clinical relevance estimation. RESULTS Two hundred forty patients with laparoscopic resection and 222 with open resection were evaluable for analysis of the 486 enrolled. Successful resection occurred in 81.7%of laparoscopic resection cases (95%CI, 76.8%–86.6%) and 86.9%of open resection cases (95%CI, 82.5%–91.4%) and did not support noninferiority (difference, −5.3%; 1-sided 95%CI, −10.8%to ∞; P for noninferiority = .41). Patients underwent low anterior resection (76.7%) or abdominoperineal resection (23.3%). Conversion to open resection occurred in 11.3%of patients. Operative time was significantly longer for laparoscopic resection (mean, 266.2 vs 220.6 minutes; mean difference, 45.5 minutes; 95%CI, 27.7–63.4; P < .001). Length of stay (7.3 vs 7.0 days; mean difference, 0.3 days; 95%CI, −0.6 to 1.1), readmission within 30

    Since its first described case in 1991, laparoscopic colon surgery has lagged behind minimally invasive surgical methods for solid intra-abdominal organs in terms of acceptability, dissemination, and ease of learning. In colon cancer, initial concerns over port site metastases and adequacy of oncologic resection have considerably dampened early enthusiasm for this procedure. Only recently, with the publication of several large, randomized controlled trials, has the incidence of port site metastases been shown to be equivalent to that of open resection. Laparoscopic surgery for colon cancer has also been demonstrated to be at least equivalent to traditional laparotomy in terms of adequacy of oncologic resection, disease recurrence, and long-term survival. In addition, numerous reports have validated short-term benefits following laparoscopic resection for cancer, including shorter hospital stay, shorter time to recovery of bowel function, and decreased analgesic requirements, as well as other postoperative variables. In benign colonic disease, much less high-quality literature exists supporting the use of laparoscopic methods. Two recent randomized controlled trials have demonstrated some short-term benefits to laparoscopic ileocolic resection for CD, in addition to evident cosmetic advantages. On the other hand, the current evidence on laparoscopic surgery for UC does not support its routine use among nonexpert surgeons outside of specialized centers. Laparoscopic colonic resection for diverticular disease appears to provide several short-term benefits, although these advantages may not translate to cases of complicated diverticulitis. Despite the increasing acceptability of minimally invasive methods for the management of benign and malignant colonic pathologies, laparoscopic colon resection remains a prohibitively difficult technique to master. Numerous technological innovations have been introduced onto the market in an effort to decrease the steep learning

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

    Synopsis Treating a fracture of the distal radius may require the surgeon to make a difficult decision between surgical treatment and nonsurgical management. The use of surgical fixation has recently increased owing to complications associated with conservative treatment. However, conservative action may be necessary depending on certain patient factors. The treating surgeon must be aware of the possible complications associated with distal radius fracture treatments to prevent their occurrence. Prevention can be achieved with a proper understanding of the mechanism of these complications. This article discusses the most recent evidence on how to manage and prevent complications following a fracture of the distal radius. PMID:25934197

    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.

    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

    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.

    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.

    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.

    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.

Thirty-seven patients underwent laparoscopic appendectomy, and 34 had open appendectomy through a right lower quadrant incision. Length of surgery, postoperative morbidity and length of postoperative stay (LOS) were recorded. Both groups were similar with regard to age, gender, height, weight, fever, leukocytosis, and incidence of normal vs. gangrenous or perforated appendix. Results: Mean LOS was significantly shorter for patients with acute suppurative appendicitis who underwent laparoscopic appendectomy (2.5 days vs. 4.0 days, p<0.01). Mean LOS was no different when patients classified as having gangrenous or perforated appendicitis were included in the analysis (3.7 days vs. 4.1 days, P=0.11). The laparoscopy group had significantly longer surgery times (72 min vs. 58 min, p<0.001). There was no significant difference in the incidence of postoperative morbidity. Conclusions: Laparoscopic appendectomy reduces LOS as compared with the traditional open technique in patients with acute suppurative appendicitis. The longer operative time for the laparoscopic approach in our study is likely related to the learning curve associated with the procedure and did not increase morbidity. PMID:9876729

    Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

    Laparoscopic surgery provides a very complex example of medical image interpretation. The task entails: visually examining a display that portrays the laparoscopic procedure from a varying viewpoint; eye-hand coordination; complex 3D interpretation of the 2D display imagery; efficient and safe usage of appropriate surgical tools, as well as other factors. Training in laparoscopic surgery typically entails practice using surgical simulators. Another approach is to use cadavers. Viewing previously recorded laparoscopic operations is also a viable additional approach and to examine this a study was undertaken to determine what differences exist between where surgeons look during actual operations and where they look when simply viewing the same pre-recorded operations. It was hypothesised that there would be differences related to the different experimental conditions; however the relative nature of such differences was unknown. The visual search behaviour of two experienced surgeons was recorded as they performed three types of laparoscopic operations on a cadaver. The operations were also digitally recorded. Subsequently they viewed the recording of their operations, again whilst their eye movements were monitored. Differences were found in various eye movement parameters when the two surgeons performed the operations and where they looked when they simply watched the recordings of the operations. It is argued that this reflects the different perceptual motor skills pertinent to the different situations. The relevance of this for surgical training is explored.

    Laparoscopic cholecystectomy has been considered as a safe and effective procedure without randomised prospective trial. Two physician insurers associations (in France and in USA) have shown an important increase of the lawsuits after laparoscopic cholecystectomy, especially concerning common bile duct injuries. An exhaustive study of the literature demonstrates that in the rare prospective studies collecting all of the laparoscopic cholecystectomies realised in one country or one state, the percentage of biliary tract injuries is form twice to five times as big as with open surgery, and bigger in case of acute cholecystitis. It seems that diffusion of the monopolar current can explain a good number of them. These injuries are difficult for repairing because of their high localisation and the associated tissular burn. Their long term morbidity is important and their cost is huge. Three recent prospective studies comparing laparoscopic versus minilaparotomy approach demonstrate that the advantages of laparoscopic approach according to the cost and the recovery's speed are, except for the obese patients, less evident than one could believe.

    Aim: In this review, we assessed the feasibility of total laparoscopic hysterectomy (TLH) in cases of very large uteri weighing more than 500 grams. We have analyzed whether it is possible for an experienced laparoscopic surgeon to perform efficient total laparoscopic hysterectomy for large myomatous uteri regardless of the size, number and location of the myomas. Design: Retrospective review (Canadian Task Force Classification II-1) Setting: Dedicated high volume Gynecological laparoscopy centre. Patients: 173 women with symptomatic myomas who underwent total laparoscopic hysterectomy at our center. There were no exclusion criteria based on the size number or location of myomas. Intervention: TLH and modifications of performing the surgery by ligating the uterine arteries prior, myomectomy followed by hysterectomy, direct morcellation after uterine artery ligation. Results: 72% of patients had previous normal vaginal delivery and 28% had previous cesarean section. Average clinical size of the uterus was 18 weeks (10, 32). The average weight of the specimen was 700 grams (500, 2240). The average duration of surgery was 107 min (40, 300) and the average blood loss was 228 ml (10, 3200). Conclusion: Total laparoscopic hysterectomy is a technically feasible procedure. It can be performed by experienced surgeons for large uteri regardless of the size, number or location of the myomas.

    Laparoscopic adrenalectomy is one of the most significant advances in the past 20 years for treating adrenal disorders. When compared with open adrenalectomy, laparoscopic adrenalectomy is equally safe, effective, and curative; it is more successful in shortening hospitalization and convalescence and has less long-term morbidity. The laparoscopic approach is the procedure of choice for the surgical management of cortisol-producing adenomas and for patients who have corticotropin (ACTH)-dependent Cushing's syndrome for whom surgery failed to remove the source of ACTH. The keys to successful laparoscopic adrenalectomy are appropriate patient selection, knowledge of anatomy, delicate tissue handling, meticulous hemostasis, and experience with the technique of laparoscopic adrenalectomy.

    Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

    Laparoscopic surgery is one of the most challenging surgical operations, because inside information about the target organ cannot be fully understood from the laparoscopic image. Therefore, a fusion technique of laparoscopic and ultrasonic images is proposed for guidance during laparoscopic surgery. The proposed technique can display the internal organ structure by overlaying a three-dimensional (3D) ultrasonic image over a 3D laparoscopic image, which is acquired using a stereo laparoscope. The registration of the 3D images is performed by registering the surface of the target organ, which is found in the two 3D images without requiring the use of an external position detecting device. The proposed technique was evaluated experimentally using a tissue-mimicking phantom. Results obtained led to registration accuracy better than 2 cm. The total computation time was 3.1 min on a personal computer (Xeon processor, 3 GHz CPU). The structural information permits the visualization of target organs during laparoscopic surgery.

    This work reports a miniaturized laparoscopic zoom camera that can significantly improve vision for minimally invasive surgery (MIS), also known as laparoscopic surgery. The laparoscopic zoom camera contains bioinspired fluidic lenses that can change curvature and focal length in a manner similar to the crystalline lenses in human eyes. The traditional laparoscope is long, rigid, and made of fixed glass lenses with a fixed field of view. The constricted vision of a laparoscope is often an inconvenience and plays a role in many surgical injuries. To further advance MIS technology, we developed a new type of laparoscopic camera that has a total length of less than 17 mm, greater than 4× optical zoom, and 100 times higher sensitivity than today's laparoscope allowing it to work under illumination as low as 300 lux. All these unique features are enabled by the technology of bioinspired fluidic lenses having a dynamic range over 100 diopters and being convertible between a convex and concave shape.

    Background and Objectives: Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. Methods: Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland. Results: Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5×3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported. Conclusion: Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.

    Laparoscopic adrenalectomy, if done by skilled surgeons, is now the first choice for treating most adrenal tumors, including bilateral pheochromocytoma. We report two women, aged 35 and 34 years old, with bilateral adrenal pheochromocytoma successfully excised by laparoscopic surgery. Both had severe hypertension, high urinary catecholamine values (epinephrine + norepinephrine: 528 and 1083 ug/24 h) and bilateral adrenal tumors at CT scan. After 4 weeks of doxazosin treatment, a laparoscopic transperitoneal adrenalectomy was done (Gugner's technique), with surgical times of 7 and 5 hours respectively. Both patients received hydrocortisone and only the second one required one unit of packed cells. Postoperative evolution was uneventful and both patients were discharged at the fifth postoperative day. At two months of follow up, both patients are asymptomatic and normotensive.

    Today largely diffused is the concept that laparoscopic cholecystectomy (LC) represents the treatment of choice for symptomatic gallstones. Nonetheless some questions have been raised on the real safety of this new method in terms of procedure-related complications. On the basis of our experience with traditional open cholecystectomy, we have recently performed a prograde LC in those cases with difficulties in identifying the anatomical structures of the so called Calot's triangle. This alternative route can be easily performed laparoscopically and has been useful in reducing the time of the intervention in the most difficult setting and to increase the safety of the procedure. The technical details and the results are compared with those of the laparoscopic retrograde route.

    Minimally invasive procedures have revolutionised surgery by reducing pain and the length of hospital stay for patients. These are not simple procedures and training in laparoscopic surgery is an arduous process. Meticulous preparation prior to surgery is paramount to prevent complications. We report a rare complication involving a 35-year-old patient who underwent a laparoscopic appendicectomy for a perforated appendix. Two days after surgery the patient experienced redness and swelling in the lower abdominal region and oliguria. A delayed computer tomography (CT) scan revealed contrast leakage around the bladder spreading within the peritoneal cavity consistent with an intraperitoneal bladder perforation. She underwent urinary catheterisation for 6 days. A follow-up CT cystogram showed no evidence of leakage into the peritoneal cavity. This case highlights the need for thorough preparation prior to laparoscopic surgery and careful manipulation of instruments during routine procedures to minimise the risk of serious patient complications such as the aforementioned.

    A 44-year-old man presented for elective laparoscopic adrenalectomy. During the procedure his end-tidal carbon dioxide readings rose steadily. We assumed that this was due to a prolonged carbon dioxide pneumoperitoneum until he developed ST segment depression on his electrocardiogram and a rapid rise in temperature. A diagnosis of malignant hyperthermia was made in view of the rising temperature and carbon dioxide. He responded to cooling and intravenous dantrolene. He was later confirmed to be malignant hyperthermia-susceptible on in vitro contracture testing of a muscle biopsy. The diagnosis was delayed as the early signs of malignant hyperthermia are the same as the expected physiological changes in laparoscopic surgery. As laparoscopic surgery continues to expand we advocate vigilance to ensure early identification of this rare but potentially devastating condition.

    Twelve children underwent elective laparoscopic cholecystectomy for symptomatic cholelithiasis during a 10-month period in one institution. The operative technique that has been described for adults was modified because of the smaller dimensions of pediatric patients. These modifications are discussed in this report, as are new alternatives for evaluating the common duct. No operative complications or conversions to open cholecystectomy occurred, and no complications after surgery were seen during an average follow-up period of 4.5 months. The benefits of laparoscopic cholecystectomy include decreased pain and ileus after surgery, shortened hospitalization, and improved cosmesis. Laparoscopic cholecystectomy is safe and efficacious in children, and it compares favorably with traditional cholecystectomy in the pediatric age group. Images FIG. 3. PMID:1532120

    Bowel perforation is a rare complication of laparoscopic cholecystectomy, which if left undiagnosed can have fatal consequences. In addition, isolated small bowel perforation is extremely rare and should be considered in patients presenting with sudden onset abdominal pain in the postoperative period. A 57-year-old male with symptomatic gallstones underwent urgent laparoscopic cholecystectomy and was discharged home on postoperative day (POD) 1 without complications. He presented to the emergency department on POD 11 complaining of sudden onset abdominal pain. A CT scan did not confirm a diagnosis and he was admitted for observation. On post admission day 2, he became significantly peritonitic and laparotomy revealed jejunal perforation. Bowel resection with hand-sewn anastomosis was completed and he was discharged on POD 10. Follow-up at 6 weeks revealed no further issues. We review the literature on small bowel perforation post laparoscopic cholecystectomy. PMID:26908534

    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.

    Background A phase III clinical trial has already shown the survival benefits of postoperative chemotherapy in gastric cancer. However, there are limited published data concerning the elderly. This study aims to investigate the use of adjuvant chemotherapy for gastric cancer after D2 gastrectomy among the elderly and identify its impact on survival. Methods We retrospectively reviewed 360 patients who had undergone D2 gastrectomy, aged 65 years or older, with non-metastatic gastric cancer in a single institution. We analyzed the predictors and survival benefits of adjuvant chemotherapy use in the elderly. Further, we analyzed the survival benefits of adjuvant chemotherapy by dividing the patients into groups according to disease stages and chemotherapeutic regimens. Results Among the 360 patients, only 34.7% of patients received adjuvant chemotherapy. Age, tumor location, lymph node involvement and tumor invasion were associated with the receipt of adjuvant chemotherapy. Adjuvant chemotherapy improved the overall survival for non-metastatic elderly patients (HR 0.60, 95%CI 0.42–0.83, P = 0.003). Significant survival benefits were found with adjuvant chemotherapy in stage III patients (HR 0.67, 95%CI 0.47–0.97, P = 0.033), but not in stage I patients or in stage II patients (HR 0.52, 95%CI 0.21–1.30 P = 0.161). Compared to adjuvant chemotherapy without platinum, no significant survival benefits were observed with platinum-containing chemotherapy (HR 0.84, 95%CI 0.49–1.45, P = 0.530). Besides adjuvant chemotherapy, other independent prognostic factors of survival included tumor location, tumor size, histologic grade, depth of tumor invasion, and lymph node status. Conclusions This study demonstrated the survival benefits of adjuvant fluoropyrimidine-based chemotherapy among the elderly patients with non-metastatic gastric cancer after D2 gastrectomy. However, due to the limitations of this study, further well-designed prospective studies with

    AIM: To investigate adjuvant chemotherapy, p53 and carcinoembryonic antigen (CEA) expression and prognosis after D2 gastrectomy for stage II/III gastric adenocarcinoma. METHODS: A total of 286 patients with stage II or III gastric adenocarcinoma who underwent D2 radical gastrectomy between May 2007 and December 2010 were enrolled into this study. One hundred and sixty-nine of these patients received surgery plus adjuvant chemotherapy, and 117 patients received surgery alone. Tumor expression of p53 and CEA proteins in all patients was evaluated immunohistochemically and correlated with clinicopathological parameters. The Kaplan-Meier curves for overall survival (OS) and disease-free survival (DFS) with log-rank testing were used to compare the survival difference. A Cox proportional hazard regression model was used for multivariate analysis. RESULTS: Patients with adjuvant chemotherapy had a significantly better median OS (50.87 mo vs 30.73 mo, P = 0.000) and median DFS (36.30 mo vs 25.60 mo, P = 0.001) than patients with surgery alone in the entire cohort. Consistent results with the entire cohort were found in stage II (P = 0.006 and P = 0.047), stage III (P = 0.005 and P = 0.030), and stage IIIB/IIIC patients (P = 0.000 and P = 0.001). The median OS and DFS advantages were confirmed by multivariate analysis (P = 0.000 and P = 0.008) and maintained when the analyses were restricted to fluoropyrimidine monotherapy (P = 0.003 and P = 0.001) and fluoropyrimidine plus platinum regimen (P = 0.001 and P = 0.007), however, not the fluoropyrimidine plus taxane (P = 0.198 and P = 0.777) or platinum plus taxane (P = 0.666 and P = 0.687) regimens. Median OS and median DFS did not differ significantly between the patients with p53(+) and p53(-) tumors (P = 0.608 and P = 0.064), or between patients with CEA(+) and CEA(-) tumors (P = 0.052 and P = 0.989), which were maintained when the analyses were restricted to surgery alone (p53: P = 0.864 and P = 0.431; CEA: P = 0.142 and

    AIM: To review current applications of the laparoscopic surgery while highlighting the standard procedures across different fields. METHODS: A comprehensive search was undertaken using the PubMed Advanced Search Builder. A total of 321 articles were found in this search. The following criteria had to be met for the publication to be selected: Review article, randomized controlled trials, or meta-analyses discussing the subject of laparoscopic surgery. In addition, publications were hand-searched in the Cochrane database and the high-impact journals. A total of 82 of the findings were included according to matching the inclusion criteria. Overall, 403 full-text articles were reviewed. Of these, 218 were excluded due to not matching the inclusion criteria. RESULTS: A total of 185 relevant articles were identified matching the search criteria for an overview of the current literature on the laparoscopic surgery. Articles covered the period from the first laparoscopic application through its tremendous advancement over the last several years. Overall, the biggest advantage of the procedure has been minimizing trauma to the abdominal wall compared with open surgery. In the case of cholecystectomy, fundoplication, and adrenalectomy, the procedure has become the gold standard without being proven as a superior technique over the open surgery in randomized controlled trials. Faster recovery, reduced hospital stay, and a quicker return to normal activities are the most evident advantages of the laparoscopic surgery. Positive outcomes, efficiency, a lower rate of wound infections, and reduction in the perioperative morbidity of minimally invasive procedures have been shown in most indications. CONCLUSION: Improvements in surgical training and developments in instruments, imaging, and surgical techniques have greatly increased safety and feasibility of the laparoscopic surgical procedures.

    Objectives The laparoscopic appendicectomy can be performed using one to several ports. We present our experience of two port laparoscopic assisted open appendicectomy. The objective was to assess the results retrospectively in terms of complications and its limitations. Methods Between years 1998-2007, a two port laparoscopic assisted appendectomy was attempted in 2380 adult patients with suspected appendicitis. The patients with localized or generalized peritonitis were included. The appendicectomy was performed via an assisted two port method using 10 mm umbilical optical port and another 10 mm port in right iliac fossa. The children aged 12 and below and pregnant patients were excluded. All patients had their laparoscopic appendicectomy within 48 hours of admission. Results Two port laparoscopic assisted appendicectomy was successful in 86.9% of cases. Acute appendicitis was the cause of acute abdomen in 88.9% of the patients. The accessory port was required in 8.5% of patients to complete the appendicectomy and the conversion rate to open was 4.6%. The mean operation time was 25 minutes and the mean hospital stay was 1.5 days. The port site infection was seen in 14, bleeding in 20, parietal wall abscess in three cases and intra-abdominal abscesses in 4 patients. Conclusion This approach is simple, can be converted to total intracorporeal by inserting accessory port or to open appendicectomy when required and has advantage of full laparoscopy of abdomen. It has its limitations in cases of extreme obesity, thick mesentery, gangrenous appendix, very large and thick appendix, and difficulty in finding the appendix, control of bleeding, division of adhesions and to deal with other associated pathology. Cost was minimized by using non-disposable port. The overall morbidity was low. There were no specific complications related to this technique and incidence of port site infection was similar to other approaches of laparoscopic appendicectomy. PMID:22359707

    Background and Objectives: Rectal prolapse is often repaired laparoscopically, frequently with the use of reinforcement material. Both synthetic and biologically derived materials reduce recurrence rate compared to primary suture repair. Synthetic mesh introduces potential complications such as mesh erosion, fibrosis, and infection. Urinary bladder matrix (UBM) represents a biologically derived material for reinforcement of rectal prolapse repair with the potential to improve durability without risks of synthetic materials. The objective of the study is to evaluate the effectiveness, durability, and functional result of laparoscopic rectopexy using urinary bladder matrix xenograft reinforcement at three years follow up. Methods: The 20 cases presented describe rectal prolapse repair by means of laparoscopic rectopexy with presacral UBM reinforcement. Patients were followed up for an average of 3 years and assessed with interviews, physical examination, manometry, and the fecal incontinence severity index (FISI). Results: Each repair was completed laparoscopically. UBM exhibited favorable handling characteristics when sutured to the sacrum and the lateral rectal walls. One patient underwent laparoscopic drainage of a postoperative abscess; no other complications occurred. In 3 years of follow-up, there have been no full-thickness recurrences, erosions, reoperations, or long-term complications. Two patients exhibited a small degree of mucosal prolapse on follow-up physical examination that did not require surgery. Three-year FISI scores averaged 8 (range, 0–33 of a possible 61), indicating low fecal incontinence symptomatology. Follow-up anorectal manometry was performed in 9 patients, showing mixed results. Conclusion: Surgeons may safely use laparoscopic rectopexy with UBM reinforcement for repair of rectal prolapses. In this series, repairs with UBM grafts have been durable at 3-year follow-up and may be an alternative to synthetic mesh reinforcement of rectal

    The history of bariatric surgery is investigational. Dedicated surgeons have continuously sought for an ideal procedure to relieve morbidly obese patients from their burden of comorbid conditions, reduced life expectancy and low quality of life. The ideal procedure must have low complication risk, both in short- and long term, as well as minimal impact on daily life. The revolution of laparoscopic techniques in bariatric surgery is described in this summary. Advances in minimal invasive techniques have contributed to reduced operative time, length of stay, and complications. The development in bariatric surgery has been exceptional, resulting in a dramatic increase of the number of procedures performed world wide during the last decades. Although, a complex bariatric procedure can be performed with operative mortality no greater than cholecystectomy, specific procedure-related complications and other drawbacks must be taken into account. The evolution of laparoscopy will be the legacy of the 21st century and at present, day-care surgery and further reduction of the operative trauma is in focus. The impressive effects on comorbid conditions have prompted the adoption of minimal invasive bariatric procedures into the field of metabolic surgery. PMID:25386062

    Background and Objectives: The purpose of this study was to analyze the surgical technique, postoperative complications, and possible recurrence after laparoscopic ventral hernia repair (LVHR) in comparison with open ventral hernia repair (OVHR), based on the international literature. Database: A Medline search of the current English literature was performed using the terms laparoscopic ventral hernia repair and incisional hernia repair. Conclusions: LVHR is a safe alternative to the open method, with the main advantages being minimal postoperative pain, shorter recovery, and decreased wound and mesh infections. Incidental enterotomy can be avoided by using a meticulous technique and sharp dissection to avoid thermal injury. PMID:26273186

    Intrahepatic subcapsular hematoma after laparoscopic cholecystectomy is a rare complication and is potentially life threatening. When radiologic studies confirm the presence of the hematoma, the decision to follow a conservative treatment should involve clinical monitoring. If there are signs of infection, the collection can safely be drained percutaneously. If there are signs of active bleeding, a selective embolization should be attempted first. If unsuccessful, subsequent surgical evacuation should be performed. We report the case of a patient with an intrahepatic subcapsular hematoma after laparoscopic cholecystectomy, which occurred 6 weeks after surgery, and review the literature concerning the management of these bleedings.

    Of 61 consecutive patients undergoing laparoscopic cholecystectomy, 4 (6.25%) developed abdominal wall haematomas. This complication of laparoscopic cholecystectomy may occur more commonly than existing literature suggests, and manifests in the post-operative period (days 2 to 6) by visible bruising, excessive pain or an asymptomatic drop in haematocrit. It is readily confirmed by ultrasonography. While no specific treatment is necessary apart from replacement of significant blood loss, the patient requires reassurance that this apparently alarming complication will rapidly resolve.

    Abdominal incisional hernia is a common complication after open abdominal operations. Laparoscopic procedures have obvious mini-invasive advantages for surgical treatment of abdominal incisional hernia, especially to cases with big hernia defect. Laparoscopic repair of incisional hernia has routine mode but the actual operations will be various according to the condition of every hernia. Key points of these operations include design of the position of trocars, closure of defects and fixation of meshes. The details of these issues and experiences of perioperative evaluation and treatment will be talked about in this article. PMID:27761446

    Duplication of the gallbladder is a rare congenital anomaly of the gallbladder, with an estimated prevalence of 1–3 per 3800 individuals. Unless properly diagnosed preoperatively, it can lead to biliary tract injuries and postoperative complications which may require reoperative surgeries. While previously reported cases have been treated with conventional laparoscopic cholecystectomy (LC), treatment with single incision laparoscopic surgery (SILS) has not been reported yet. We herein present the case of a 58-year-old female with gallbladder duplication who was successfully treated with SILS cholecystectomy. PMID:26266074

    Fibroepithelial polyps of the ureter are rare benign mesothelial tumors. Most polyps are small; however, very rare large polyps have also been reported. Currently, most investigators encourage endoscopic management in these patients. Nevertheless, endoscopic resection can be difficult in patients with a long or large polypoid lesion. We describe our experience and laparoscopic technique for treatment of a symptomatic 42-year-old woman who presented with a 17-cm-long fibroepithelial polyp in the proximal ureter associated with ureteral obstruction. To our knowledge, this is the first reported case of laparoscopic management of a large ureteral fibroepithelial polyp.

    Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

    2016-01-01

    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.

    Abstract Rationale: Cholesterol polyps are rare in the common bile duct and difficult to diagnose. Patient concerns: The small polypoid lesions often go undetected when using routine imaging methods, such as ultrasonography. Diagnoses: We treated a patient with cholesterol polyps in the common bile duct. After failing to detect choleliths using ultrasonography, magnetic resonance cholangiopancreatography revealed mild dilation of the common bile duct. Choledochoscopy was performed during laparoscopic cholecystectomy, which revealed yellowish-white polyps circumferentially distributed across the luminal surface of the distal common bile duct. Histological examination of biopsy specimens indicated cholesterol polyps with characteristic foamy cells. Interventions: The patient was treated with ursodeoxycholic acid, and the number of polyps was found to have been reduced at the 6-week follow-up based on T-tube choledochoscopic examination. Outcomes: Recovery was unremarkable, and the ursodeoxycholic acid treatment was discontinued at the 6-month follow-up. Lessons subsections: Our findings suggest that this rare condition can be treated pharmacologically to avoid potential postsurgical complications following resection of the distal common bile duct.

    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.

    Background Both gastric bypass (GB) and duodenal switch with sleeve gastrectomy (DS) have been widely used as bariatric surgeries, and DS appears to be superior to GB. The aim of this study was to better understand the mechanisms leading to body weight loss by comparing these two procedures in experimental models of rats. Methods Animals were subjected to GB, DS or laparotomy (controls), and monitored by an open-circuit indirect calorimeter composed of comprehensive laboratory animal monitoring system and adiabatic bomb calorimeter. Results Body weight loss was greater after DS than GB. Food intake was reduced after DS but not GB. Energy expenditure was increased after either GB or DS. Fecal energy content was increased after DS but not GB. Conclusion GB induced body weight loss by increasing energy expenditure, whereas DS induced greater body weight loss by reducing food intake, increasing energy expenditure and causing malabsorption in rat models.

    The authors report on a case of digestive bleeding (melaena and enterorrhagia) in a patient undergoing total gastrectomy for gastric cancer and later splenectomy for subcapsular haematoma in a different hospital. The source of bleeding was not intraluminal; the bleeding arose from double erosion of the gastroduodenal artery in the tract above the anterior surface of the pancreas, close to the dehiscent duodenal stump. The blood flowed mainly into the enteric district through the open stump thus causing the clinical signs described. The diagnosis was made during an emergency surgical operation for haemorrhagic shock. The patient underwent haemostasis with two stitches on the gastroduodenal artery, external drainage of the duodenum with a Petzer tube, laparostomy of the infected area and ileostomy. After three months he had completely recovered.

    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

    Objective. To review the vaginal cuff complications from a large series of total laparoscopic hysterectomies in which the laparoscopic culdotomy closure was highly standardized. Methods. Retrospective cohort study (Canadian Task Force Classification II-3) of consecutive total and radical laparoscopic hysterectomy patients with all culdotomy closures performed laparoscopically was conducted using three guidelines: placement of all sutures 5 mm deep from the vaginal edge with a 5 mm interval, incorporation of the uterosacral ligaments with the pubocervical fascia at each angle, and, whenever possible, suturing the bladder peritoneum over the vaginal cuff edge utilizing two suture types of comparable tensile strength. Four outcomes are reviewed: dehiscence, bleeding, infection, and adhesions. Results. Of 1924 patients undergoing total laparoscopic hysterectomy, 44 patients (2.29%) experienced a vaginal cuff complication, with 19 (0.99%) requiring reoperation. Five patients (0.26%) had dehiscence after sexual penetration on days 30–83, with 3 requiring reoperation. Thirteen patients (0.68%) developed bleeding, with 9 (0.47%) requiring reoperation. Twenty-three (1.20%) patients developed infections, with 4 (0.21%) requiring reoperation. Three patients (0.16%) developed obstructive small bowel adhesions to the cuff requiring laparoscopic lysis. Conclusion. A running 5 mm deep × 5 mm apart culdotomy closure that incorporates the uterosacral ligaments with the pubocervical fascia, with reperitonealization when possible, appears to be associated with few postoperative vaginal cuff complications.

    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.

    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.

    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.

    Introduction Obesity has recently become a major health problem, and researchers have been directed to work toward the development of surgical techniques, with new mediators playing an important role in nutrition. Gastric plication (GP) and sleeve gastrectomy (SG) have become popular recently. These are widely used techniques in bariatric surgery. Objectives In this study, we aimed to compare the efficiency of SG and GP techniques on rats. Methods Wistar-Hannover rats (n=18) were divided into three equal groups, namely SG, GP, and control. Blood samples were taken before the operation and on the 30th day after the operation. The weights of all rats were recorded both on first day and the 30th day after the operation. Serum gastrin, ghrelin, and leptin levels were also measured on the same days. For histopathological examination, gastrectomy was performed after the animals were sacrificed. Results Average weight loss was 10% for the SG group and 6.5% for the GP group. One month after the operations, the decrease in the ghrelin and leptin levels of GP and SG groups was significant compared with the levels of the control group. Gastrin levels of the SG group increased significantly compared with those of the control group. Histopathological examination revealed that there was significant decrease in the ghrelin and leptin levels of the GP and SG groups compared with those of the control group. Foveolar hyperplasia (FH), cystic glandular dilatation, and fibrosis were significantly higher in the GP and SG groups compared with the control group. Conclusion Although GP is not as effective as SG in terms of weight loss, it provides the same effectiveness in decreasing ghrelin and leptin levels. Histopathological findings revealed that FH, fibrosis, and the cystic glandular dilatation development rates were similar. PMID:27087477

    AIM To evaluate the risks of medical conditions, evaluate gastric sleeve narrowing, and assess hydrostatic balloon dilatation to treat dysphagia after vertical sleeve gastrectomy (VSG). METHODS VSG is being performed more frequently worldwide as a treatment for medically-complicated obesity, and dysphagia is common post-operatively. We hypothesize that post-operative dysphagia is related to underlying medical conditions or narrowing of the gastric sleeve. This is a retrospective, single institution study of consecutive patients who underwent sleeve gastrectomy from 2013 to 2015. Patients with previous bariatric procedures were excluded. Narrowing of a gastric sleeve includes: inability to pass a 9.6 mm gastroscope due to stenosis or sharp angulation or spiral hindering its passage. RESULTS Of 400 consecutive patients, 352 are included; the prevalence of dysphagia is 22.7%; 33 patients (9.3%) have narrowing of the sleeve with 25 (7.1%) having sharp angulation or a spiral while 8 (2.3%) have a stenosis. All 33 patients underwent balloon dilatation of the gastric sleeve and dysphagia resolved in 13 patients (39%); 10 patients (30%) noted resolution of dysphagia after two additional dilatations. In a multivariate model, medical conditions associated with post-operative dysphagia include diabetes mellitus, symptoms of esophageal reflux, a low whole blood thiamine level, hypothyroidism, use of non-steroidal anti-inflammatory drugs, and use of opioids. CONCLUSION Narrowing of the gastric sleeve and gastric sleeve stenosis are common after VSG. Endoscopic balloon dilatations of the gastric sleeve resolves dysphagia in 69% of patients. PMID:28058017

    Introduction: Laparoscopic gastric plication (LGCP) reduces gastric volume without resecting or implanting a foreign body. Although still considered investigational, it could be appropriate for young patients with a low body mass index (BMI) and for those unwilling to undergo sleeve gastrectomy, gastric banding, or bypass. Objectives: The aim of this study was to assess the mid-term results (2 years) of LGCP in terms of safety and efficacy. Methods: A total of 56 obese patients (47 female; mean age=30.5±11.7 years; mean BMI=40.31±4.7 kg/m2) were candidates for LGCP from January 2011 to October 2013. Early and late complications, BMI, and excess BMI loss (EBL) were prospectively recorded at 3, 6, 9, 12, 18, and 24 months follow-up. Results: Mean operative time was 72.4±15.6 minutes. No conversion was required. Mean hospital stay was 3 days. Mean %EBL was 34.3±18.40%, 40.1±24.5%, 47.4±30.2%, 46.5±34.6%, 47.8±43.2%, and 55.3±53.6% at 3, 6, 9, 12, 18, and 24 months, respectively. The overall complication rate was 32.14%. Perioperative mortality was zero. Surgical revision was needed in 30 patients: 12 for unsatisfactory weight loss and 18 for gastric prolapse (one acute within 30 days), respectively. Conclusion: LGCP showed high complication rates requiring surgical revision. PMID:26421246

    To improve visualization during minimal access surgery, a novel robotic camera has been developed. The prototype camera is totally insertable, has 5 degrees of freedom, and is remotely controlled. This study compared the performance of laparoscopic surgeons using both a laparoscope and the robotic camera. The MISTELS (McGill Inanimate System for the Training and Evaluation of Laparoscopic Skill) tasks were used to test six laparoscopic fellows and attending surgeons. Half the surgeons used the laparoscope first and half used the robotic camera first. Total scores from the MISTELS sessions in which the laparoscope was used were compared with the sessions in which the robotic camera was used and then analyzed with a paired t test (P < .05 was considered significant). All six surgeons tested showed no significant difference in their MISTELS task performance on the robotic camera compared with the standard laparoscopic camera. The mean MISTELS score of 963 for all subjects who used a laparoscope and camera was not significantly different than the mean score of 904 for the robotic camera (P = .17). This new robotic camera prototype allows for equivalent performance on a validated laparoscopic assessment tool when compared with performance using a standard laparoscope.

Torsion of a wandering spleen is an unusual cause of an acute abdomen and is rarely diagnosed preoperatively. Associated torsion of the distal pancreas is even more uncommon. The authors describe a patient with torsion of a wandering spleen and distal pancreas, who was correctly diagnosed, and define the merits of the imaging methods used. The initial examination should be /sup 99//sup m/Tc-sulfur colloid liner-spleen scanning.

    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.

    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 increase of technological complexity in surgery has created a need for novel man-machine interaction techniques. Specifically, context-aware systems which automatically adapt themselves to the current circumstances in the OR have great potential in this regard. To create such systems, models of surgical procedures are vital, as they allow analyzing the current situation and assessing the context. For this purpose, we have developed a Surgical Process Model based on Description Logics. It incorporates general medical background knowledge as well as intraoperatively observed situational knowledge. The representation consists of three parts: the Background Knowledge Model, the Preoperative Process Model and the Integrated Intraoperative Process Model. All models depend on each other and create a concise view on the surgery. As a proof of concept, we applied the system to a specific intervention, the laparoscopic distal pancreatectomy.

    Purpose: To evaluate outcomes including operating time, blood loss, length of stay (LOS), return to work and complications of laparoscopic hysterectomy performed with automatic stapling devices. Methods: Between 6/11/91 and 11/23/95, 127 laparoscopic hysterectomies were performed with automatic stapling devices. On an average, 6 firings with the stapler were done per case. Postoperative telephone survey and retrospective review of records were done. Results: Data averages for operating time, blood loss, LOS and return to work, respectively, were 90 minutes, 190 cc's, 1.1 day and 2 weeks. Significant complications included delayed postoperative bleeding in 4 patients, all of which occurred within the first 35 cases. One was controlled laparoscopically and 3 others required exploratory laparotomies. Since certain precautionary measures as described were taken, hemorrhagic complications were eliminated. Conclusions: Laparoscopic hysterectomy can be performed safely and effectively with automatic stapling devices in properly selected patients. A potential hazard inherent with this technique includes intraoperative and postoperative bleeding from the staple lines, the incidence of which can be minimized by taking certain precautionary measures such as the use of white cartridges only and bipolar desiccation of staple lines when indicated.

    From 1978 to April 1980, 36 laparoscopic sterilization procedures were completed at the Gynecological Department in Maribor. For tubal occlusion in 16 cases Tupla clips and in 20 cases the Tubal Falope ring were used. It appears that the incidence of complications and other technical difficulties is somewhat more frequent with clips. There have been no pregnancies in all these cases.

    Purpose The aim of this study was to verify that laparoscopic resection for treating retroperitoneal benign neurilemmoma (NL) is expected to be favorable for complete resection of tumor with technical feasibility and safety. Methods We retrospectively analyzed 47 operations for retroperitoneal neurogenic tumor at Yonsei University College of Medicine, Severance Hospital and Gangnam Severance Hospital between January 2005 and September 2015. After excluding 21 patients, the remaining 26 were divided into 2 groups: those who underwent open surgery (OS) and those who underwent laparoscopic surgery (LS). We compared clinicopathological features between the 2 groups. Results There was no significant difference in operation time, estimated blood loss, transfusion, complication, recurrence, or follow-up period between 2 groups. Postoperative hospital stay was significantly shorter in the LS group versus the OS group (OS vs. LS, 7.00 ± 3.43 days vs. 4.50 ± 2.16 days; P = 0.031). Conclusion We suggest that laparoscopic resection of retroperitoneal benign NL is feasible and safe by obtaining complete resection of the tumor. LS for treating retroperitoneal benign NL could be useful with appropriate laparoscopic technique and proper patient selection. PMID:28289669

    Background and Objectives: Laparoscopic inguinal hernia repair has become increasingly popular as an alternative to open surgery. The purpose of this study was to evaluate the safety and effectiveness of the laparoscopic total extraperitoneal procedure with the use of staple fixation and polypropylene mesh. Methods: A retrospective chart review examined outcomes of 1240 laparoscopic hernia operations in 783 patients, focusing on intraoperative and early postoperative complications, pain, and time until return to work and normal physical activities. Results: There were no intraoperative complications in this series; 106 patients experienced early postoperative complications across 8 evaluated categories: urinary retention (4.1%), seroma (3.0%), testicular/hemiscrotal swelling (1.9%), testicular atrophy (0%), hydrocele (0.6%), mesh infection (0.1%), and neurological symptoms (transient, 1.0%; persistent, 0.2%). Patients used an average of 5.6 Percocet pills after the procedure, and mean times until return to work and normal activities, including their routine exercise regimen, were 3.0 and 3.8 days, respectively. Conclusion: Complication rates and convalescence times were considered equivalent or superior to those found in other studies assessing both laparoscopic and open techniques. The usage of multiple Endostaples did not result in increased neurologic complications in the early postoperative period when compared with findings in the literature. In the hands of an experienced surgeon, total extraperitoneal repair is a safe, effective alternative to open inguinal hernia repair. PMID:27493471

    Objectives In Oman, the most frequent indication for a splenectomy in children is sickle cell disease (SCD), which is one of the most common haematological disorders in the Gulf region. This study aimed to describe paediatric laparoscopic splenectomies alone for SCD at a tertiary hospital in Oman. Methods This study was conducted between February 2010 and October 2015 at the Sultan Qaboos University Hospital, Muscat, Oman. The medical records of all children aged ≤15 years old undergoing splenectomies during the study period were reviewed. Results A total of 71 children underwent laparoscopic splenectomies during the study period; of these, 50 children (28 male and 22 female) underwent laparoscopic splenectomies alone for SCD. The children’s weight ranged between 11–43 kg. The most common indication for a splenectomy was a recurrent splenic sequestration crisis (92%). Surgically removed spleens weighed between 155–1,200 g and measured between 9–22 cm. Operative times ranged between 66–204 minutes and intraoperative blood loss ranged between 10–800 mL. One patient required conversion to an open splenectomy. Postoperative complications were noted in only four patients. The median hospital stay duration was three days. Conclusion Among this cohort, the mean operating time was comparable to that reported in the international literature. In addition, rates of conversion and postoperative complications were very low. These findings indicate that a laparoscopic splenectomy alone in paediatric patients with SCD is a feasible option. PMID:28003896

    Patients with high grade and/or muscle invasive bladder cancer and with concomitant diseases of the upper urinary tract, e.g. urothelial tumors (transitional cell carcinoma – TCC) or afunctional hydronephrotic kidneys, may be candidates for simultaneous cystectomy and nephroureterectomy. Although the progress in laparoscopic techniques made these procedures feasible and safe, they are still technically demanding so only experienced surgeons can perform them. The aim of the study is to report our experience with laparoscopic simultaneous en bloc resection of the urinary bladder together with unilateral or bilateral nephroureterectomy in patients with TCC. Our material consists of three cases operated on in three centers between 2002 and 2011. After having completed bilateral (1 case) or unilateral (2 cases) nephroureterectomy, we performed radical cystectomy with pelvic lymph node dissection. All the specimens, including the kidneys, ureters, bladder, and reproductive organs in the female, were collected in endobags and were retrieved en bloc using hypogastric incision in the male patient and the vaginal route in the female patients. The demographic and perioperative information was collected and analyzed. All procedures were completed laparoscopically without the need of conversion to open surgery. No major intra- or postoperative complications were observed. Only 1 patient suffered from prolonged lymphatic leakage. From our experience we can conclude that single-session laparoscopic cystectomy and nephroureterectomy are technically feasible and safe, and may be offered for the treatment of selected cases of TCC of the urinary tract.

    Objective: This retrospective observational report analyzes the demographics, blood loss, length of surgical duration, number of days in the hospital, and complications for 821 consecutive patients undergoing total laparoscopic hysterectomy over a 11-year period stratified by incidental appendectomy. Methods: A retrospective chart abstraction was performed. ANOVA and chi-square tests were performed with significance preset at P<0.05. Results: Of 821 consecutive patients undergoing total laparoscopic hysterectomy, 257 underwent elective appendectomy with the ultrasonic scalpel, either as part of their staging, treatment for pelvic pain, or prophylaxis against appendicitis. Comparing the 2 groups, no difference existed in mean age of 50±10 years or mean BMI of 27.6±6.7. Both groups had a similar mean blood loss of 130 mL. Surgery took less time (137 vs 118 minutes, P<0.0012) and the hospital stay was shorter in the appendectomy group (1.5 vs 1.2, P<0.0001) possibly because it was performed incidentally in most cases. No complications were attributable to the appendectomy, and complication types and rates in both groups were similar. Though all appendicies appeared normal, pathology was documented in 9%, including 3 carcinoid tumors. Conclusions: Incidental appendectomy during total laparoscopic hysterectomy is not associated with significant risk and can be routinely offered to patients planning elective gynecologic laparoscopic procedures, as is standard for open procedures.

    Laparoscopic adrenalectomy has been rapidly accepted for treatment of benign adrenal tumors. To evaluate the advantages of laparoscopic adrenalectomy, we examined 55 patients who underwent laparoscopic adrenalectomy. In all patients, adrenal tumors were successfully removed. The mean operating time was 143 minutes, and the estimated mean blood loss was 49 mL in all patients. The postoperative course was uneventful in all cases. The mean frequency of administration of analgesics was only 2.9 times, and the time elapsed to first walking after surgery was 17 hours. The peak white blood cell count and C-reactive protein values after surgery were 8,266 +/- 1,963/mm3 and 2.5 +/- 1.2 mg/dL, respectively. Of the 55 patients, 44 underwent total adrenalectomy and another 11 underwent partial adrenalectomy, which was introduced in the expectation of preserving normal adrenal cortex; it is therefore indicated in solitary and peripherally located benign tumors. The mean operating time was 154 minutes for the total adrenalectomy, which was longer than that of partial adrenalectomy (92 minutes). The estimated blood loss was 50 mL for the total and 46 mL for the partial adrenalectomy. The postoperative course was uneventful and surgical outcome was excellent in each group. In conclusion, our results are encouraging enough to suggest that laparoscopic adrenalectomy should be a preferential therapeutic option for benign adrenal tumors; also, partial adrenalectomy could be a safe, effective, and less invasive procedure in selected cases.

    Introduction The differential outcomes of laparoscopic adrenalectomy are not well described. Therefore, we evaluated these outcomes in the 3 groups most often seen clinically: bilateral adrenalectomy for Cushing's disease (group 1), pheochromocytoma (group 2) and unilateral adrenalectomy for non-pheochromocytoma (group 3). Methods We reviewed a longitudinal database of 72 consecutive cases of laparoscopic adrenalectomy carried out between 1997 and 2001 at the Centre for Minimally Invasive Surgery, University of Toronto. Results Patients in group 1 tended to be older (median 49 yr) and heavier (median 87 kg). They had a longer operating time (median 255 min), more postoperative complications (15%) and a longer median postoperative stay (4 d). Patients in group 2 had intermediate outcomes: a median operating time of 198 minutes, complication rate of 8.3% and a median postoperative hospital stay of 3 days. However, they had more intraoperative blood loss (median 150 mL). Group 3 patients had the best outcomes with the shortest median operating time (125 min), least blood loss (median 50 mL), fewer complications (6%) and shortest hospital stay (median 2 d). Conclusions Although the outcomes of laparoscopic adrenalectomy are uniformly good, on the basis of the underlying pathologic characteristics, patients can be divided into groups that have different expected outcomes. Patients requiring a unilateral adrenalectomy except for pheochromocytoma have the best recorded outcomes. Surgeons transferring to laparoscopic adrenalectomy would benefit from selecting patients in this group during their learning curve. PMID:14577705

    2012-01-01

    Background and Objectives: To present our experience with a single-incision laparoscopic total colectomy, along with a literature review of all published cases on single-incision laparoscopic total colectomy. Methods: A total of 22 cases were published between 2010 and 2011, with our patient being case 23. These procedures were performed in the United States and United Kingdom. Surgical procedures included total colectomy with end ileostomy, proctocolectomy with ileorectal anastomosis, and total proctocolectomy with ileopouch-anal anastomosis. Intraoperative and postoperative data are analyzed. Results: Twenty-two of the 23 cases were performed for benign cases including Crohns, ulcerative colitis, and familial adenomatous polyposis. One case was performed for adenocarcinoma of the cecum. The mean age was 35.3 years (range, 13 to 64), the mean body mass index was 20.1 (range, 19 to 25), mean operative time was 175.9 minutes (range, 139 to 216), mean blood loss was 95.3mL (range, 59 to 200), mean incision length was 2.61cm (range, 2 to 3). Average follow-up was 4.6 months with 2 reported complications. Conclusions: Single-incision laparoscopic total colectomy is feasible and safe in the hands of an experienced surgeon. It has been performed for both benign and malignant cases. It is comparable to the conventional multi-port laparoscopic total colectomy. PMID:22906326

    Objective To compare dentoalveolar and skeletal changes produced by the pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients. Methods Forty-three patients (19 men, 24 women) with Class II malocclusion were retrospectively selected for the study. Twenty-four patients (mean age, 12.2 ± 1.5 years) were treated with the PA, and 19 patients (mean age, 11.3 ± 1.9 years) were treated with the DS. The mean distalization time was 7 months for the PA group and 9 months for the DS group. Lateral cephalograms were obtained at T1, before treatment, and at T2, the end of distalization. A Mann-Whitney U test was used for statistical comparisons of the two groups between T1 and T2. Results PA and DS were equally effective in distalizing maxillary molars (4.7 mm and 4.2 mm, respectively) between T1 and T2; however, the maxillary first molars showed less distal tipping in the DS group than in the PA group (3.2° vs. 9.0°, respectively). Moreover, significant premolar anchorage loss (2.7 mm) and incisor proclination (5.0°) were noted in the PA group, whereas premolar distal movement (1.9 mm) and no significant changes at the incisor (0.1°) were observed in the DS group. No significant sagittal or vertical skeletal changes were detected between the two groups during the distalization phase. Conclusions PA and DS seem to be equally effective in distalizing maxillary molars; however, greater distal molar tipping and premolar anchorage loss can be expected using PA. PMID:26258063

    Pain and instability of the distal radioulnar joint (DRUJ) are common sequelae following a fracture of the distal radius. Many soft tissue procedures have been described, not all of which are successful. Ulnar head replacement prostheses are available but do not always provide stability. We designed a two-part, easy to implant, distal radioulnar prosthesis and implanted it in 19 patients. The first prototype was inserted in 2002 and is still in place. During the study, the design was changed twice, resulting in three groups with four patients in group A, five in group B, and ten in group C. Unfortunately all five prostheses in group B had to be removed because of loosening, while only two prostheses in group C had to be removed, for nonprosthetic reasons. For the 12 patients who retained their prosthesis, forearm function increased while grip strength increased significantly. Pain scores decreased and the Disabilities of the Arm, Shoulder, and Hand (DASH) score improved but remained high. We conclude that the prosthesis offers a new treatment option for ulnar instability following distal ulnar resection. PMID:24436843

    Laparoscopic surgery has advanced remarkably in recent years, resulting in reduced morbidity and shorter hospital stay compared with open surgery. Despite challenges from the expanding array of laparoscopic procedures performed with the use of pneumoperitoneum on increasingly sick patients, anesthesia has remained largely unchanged. At present, most laparoscopic operations are usually performed under general anesthesia, except for patients deemed "too sick" for general anesthesia. Recently, however, several large, retrospective studies questioned the widely held belief that general anesthesia is the best anesthetic method for laparoscopic surgery and suggested that regional anesthesia could also be a reasonable choice in certain settings. This narrative review is an attempt to critically summarize current evidence on regional anesthesia for laparoscopic surgery. Because most available data come from large, retrospective studies, large, rigorous, prospective clinical trials comparing regional vs. general anesthesia are needed to evaluate the true value of regional anesthesia in laparoscopic surgery.

    Vascular injuries during laparoscopic cholecystectomy can occur similar to biliary injuries and mostly represented by intraoperative bleeding. Hepatic artery system pseudoaneurysm are rare. It occurs in the early or late postoperative course. Patients present with pallor, signs of haemobillia and altered liver function. We report a case of right posterior sectoral artery pseudoaneurysm detected 2 weeks after laparoscopic cholecystectomy and successfully repaired laparoscopically. We also describe how laparoscopic pringle clamping saved the conversion. The actively bleeding right posterior sectoral artery pseudoaneurysm was diagnosed by CT angiogram. Embolisation, usually the treatment of choice, would have risked liver insufficiency as hepatic artery proper was at risk because the origin the bleeding artery was just after its bifurcation. Isolated right hepatic artery embolisation can also cause hepatic insufficiency. To our knowledge this is the first reported case of laparoscopic repair of post-laparoscopic cholecystectomy bleeding sectoral artery pseudoaneurysm. PMID:24501508

    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.

    Laparoscopic surgery carries the advantage of minimal invasiveness, but ergonomic design of the instruments used has progressed slowly. Previous studies have demonstrated that the handle of laparoscopic instruments is vital for both surgical performance and surgeon's health. This review provides an overview of the sub-discipline of handle ergonomics, including an evaluation framework, objective and subjective assessment systems, data collection and statistical analyses. Furthermore, a framework for ergonomic research on laparoscopic instrument handles is proposed to standardize work on instrument design.

    Objectives This 1:1 matched cohort study with 3-year follow-up aimed to compare the safety and efficacy of LSG with LRYGB for morbid obesity patients. Methods From 2009 to 2013, patients undergoing LRYGB (n = 63) were matched with LSG (n = 63) by gender, age, and body mass index (BMI). Major complications, BMI, percentage of excess weight loss (%EWL), and obesity-related comorbidities after 6, 12, 24, and 36 months were compared. Results Hospital stay and major complication rates were comparable, but operative time in LSG was significantly shorter (83.2 ± 23.7 vs. 108.3 ± 21.3 min). No significant differences in mean %EWL and BMI were observed at 6, 12, 24 months. At 3-year follow-up, mean %EWL in the LRYGB group was significantly higher than in the LSG group (76.5 ± 9.2% vs. 65.7 ± 10.3%) and, consequently, mean BMI was significantly lower in LRYGB (28.2 ± 1.5 vs. 30.9 ± 2.4 kg/m2). No significant differences in remission of comorbidities were observed at 1- or 3-year follow-up. Conclusions Both LRYGB and LSG were safe and effective bariatric procedures in this Chinese population, but LRYGB seemed to be superior to LSG in terms of mid-term weight loss. PMID:27729621

    Although the incidence of port-site metastasis after laparoscopic surgery for colorectal cancer has markedly decreased since laparoscopic colectomy was first reported in 1991, it still has not reached zero. In colorectal cancer, the safety of laparoscopic surgery, including the low incidence of port-site metastasis, has been proven in large, randomized trials. In gastric cancer, reports of port-site metastasis are extremely rare, but we should await the results of ongoing trials. This brief review summarizes the current knowledge regarding port-site metastasis after laparoscopic surgery for colorectal and gastric cancer.

    The study suggests to make a comparative analysis between the complications happened after classic and laparoscopic surgery require a surgical reintervention. The study was realised in the Surgical Department of the Districtual Hospital Baia Mare between 27.04.1997-27.04.1999, which means the precursory year of beginning laparoscopic surgery and the first year with experience in laparoscopic surgery. The conclusions of this study prove that the number of reinterventions after laparoscopic surgery is less than after classic surgery of biliary ducts.

    Distal radioulnar arthroplasty is an attractive solution for treating various pathological conditions of the distal radioulnar joint because it allows restoration of stability, load transmission and function. The main indications are: radioulnar impingement after partial or complete resection of the distal ulna; and degenerative, inflammatory or post-traumatic arthritis of the distal radioulnar joint. The authors present three clinical cases of distal radioulnar pathological conditions: two patients with post-traumatic sequelae and one case of distal radioulnar impingement after a Sauvé-Kapandji operation. The three cases were treated surgically with a metallic prosthesis to replace the distal ulna (First Choice - Ascension®). The first two were treated with a resurfacing prosthesis and the last one with a modular prosthesis. All of the patients had achieved pain relief and increased movement of the distal radioulnar joint after one year of postoperative follow-up. PMID:27047827

    Laparoscopic surgery through a single incision is gaining popularity with different stakeholders. The advantages of improved cosmetics, decreased postoperative pain and blood loss continue to attract patients from different surgical fields. Multidisciplinary approach to different surgical entities through a single incision has just been introduced. We report the first case of a synchronous single-port access (SPA) laparoscopic right hemicolectomy and laparoscopic-assisted vaginal hysterectomy with bilateral salpingo-oophorectomy through a single incision above the umbilicus in a 48-year-old female with ascending colon mass and uterine mass with good postoperative outcomes. SPA laparoscopic surgery is feasible for multidisciplinary approach in resectable tumors. PMID:28096321

    The aim of this study was to compare the quality of life (QoL) depending on the postoperative survival period or nutritional status in gastric cancer patients. Surviving gastric cancer patients (n = 222) after the gastrectomy were included in the study at Soonchunhyang University Bucheon Hospital from April 2010 to August 2012. The Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and a gastric cancer-specific module, the EORTC QLQ-STO22, were used to assess the QoL. The postoperative survival period of the patients fell into two groups; the less-than-1-year group or the more-than-1-year group, and the nutritional status of the patients fell into three groups by a score of patient generated-subjective global assessment (SGA)-A, B, and C. As a result, the rate of malnutrition was 34.5% in the less-than-1-year group and 19.8% in the more-than-1-year group, respectively. Score for the fatigue (p = 0.006), loss of appetite (p = 0.002), reflux (p = 0.027) and body image (p = 0.004) in which the QoL was significantly lower in the less-than-1-year group than in the more-than-1-year group. The score of QoL according to the nutritional status of all subjects, overall health status (p = 0.043), physical functioning (p = 0.016), fatigue (p = 0.006), pain (p = 0.028), loss of appetite (p = 0.017), reflux (p = 0.003), eating restriction (p = 0.002), anxiety (p = 0.010), and body image (p = 0.001) was significantly lower in the SGA-C group than in other SGA groups. These results suggest that the nutritional status of the gastrectomy patients with stomach cancer may impact on their QoL. It is necessary to to develop nutritional intervention to improve QoL in gastric cancer patients with postoperative malnutrition. PMID:26251833

    Rumination syndrome is a behavioral disorder resulting in effortless regurgitation of undigested food within minutes of meal intake that is subsequently either re-swallowed or ejected. It is commonly misdiagnosed, patients often undergo extensive testing and multiple therapies, many of which are directed at suspected gastroparesis. A 25-year-old Caucasian female initially presented to our care 1 year ago with a 4-year history of nausea and vomiting occurring in the immediate postprandial period, specifically within 15 minutes from oral intake. She had an extensive history of multiple diagnostic, therapeutic and surgical procedures over the previous 4 years which included cholecystectomy, botulin toxin injection into the pyloric sphincter, pyloroplasty, placement of a gastric stimulator and jejunal feeding tube with no sustained results. On a previous admission we determined the functional status of the stomach by obtaining full thickness gastric biopsies during a diagnostic laparoscopy. This revealed an adequate population number of cells of Cajal and myenteric neurons as well as normal stomach muscle. After 1 year of attempting "breathing relaxation techniques", while being nutritionally maintained by nocturnal jejunostomy feedings, the patient presented again to our care with refractory nausea and vomiting and unable to work or function. Her weight was 90 lbs. She underwent a subtotal gastrectomy (80%) with Roux-en-Y reconstruction and continuation of jejunostomy feeding. The refractory nausea and vomiting significantly improved over the 4 weeks after discharge and breathing exercises were continued. On subsequent follow-up visits over a 6-month course, the refractory nausea and vomiting had resolved by more than 85% with and improvement in her BMI and quality of life.The recommended treatment of rumination syndrome is focused on breathing exercises and relaxation techniques to "distract" while eating. We believe our case is the first reported where a subtotal

    Published reports on laparoscopic resection of gastric gastrointestinal stromal tumor (GIST) were limited to small experiences and selection bias. Two hundred fourteen patients who underwent primary gastric GIST resection at our institution (January 2006-December 2012) were identified from a prospectively collected database. Laparoscopic resections (LAP) were performed in 133 patients, and open resections (OPEN) were performed in 81 patients. The short- and long-term outcomes were analyzed using propensity-score matching (PSM) by comparing the clinicopathological factors between these groups. The tumor resection method and tumor size were significantly different between the LAP and OPEN groups. After PSM, there were no differences (P > 0.05) in these clinicopathological factors. The LAP group had less blood loss and shorter operation time, time to first flatus, time to first fluid diet, time to gastric tube removal, and postoperative stay before PSM. In addition, there were no differences regarding the time of drainage tube removal or hospitalization expense. Other than the time of gastric tube removal, which was similar in these 2 groups, the short-term outcomes were similar before and after PSM. The rates of postoperative complications in the LAP and OPEN groups were 6.8% and 22.8%, respectively, before PSM (P = 0.001) and 5.6% and 22.5%, respectively, after PSM (P = 0.004). The multivariate analyses for complications showed that tumors were located in the middle of the stomach, and the operation method and proximal gastrectomy were independent risk factors before and after PSM. The 5-year cumulative survival rates in the LAP and OPEN groups were 95.4% and 85.9%, respectively, (P = 0.07) before PSM and 93.1% and 91.9%, respectively, (P = 0.69) after PSM (not significantly different). Laparoscopic resection for gastric GISTs had better short-term outcomes and similar long-term outcomes compared with open surgery. Localized gastric GISTs can be

    An inwardly directed curvature of the distal segment of both forelegs of the rabbit has been described. The condition was detected at 2 to 3 weeks of age, developed rapidly, and reached its final and permanent stage at 2 to 3 months of age. Only the distal epiphysis of the ulna was primarily affected and this in the form of a massive chondrodystrophic lesion accompanied by a progressive curvature of the shaft. The curvature of the growing radius was a secondary effect due to the firm, immovable, anatomical connection of the ulna and radius. The positional changes of the wrist and paw were likewise effects secondary to the changed form of the ulna and radius. The bowing abnormality occurred only in certain families of pure bred Beveren, Belgian, French Silver, and Dutch rabbits and was found to be inherited. The mode of inheritance was on the basis of a single recessive unit factor (5). PMID:13733755

    Proponents of laparoscopic appendectomy emphasize the advantages of laparoscopic operation--decreased hospitalization, paralytic ileus, postoperative pain and wound complications, including infection. This study compared open laparoscopic appendectomy with laparoscopic appendectomy. To compare the two techniques, patients undergoing laparoscopic appendectomy at four hospitals were compared with patients undergoing open appendectomy during a six month period. Excluded were incidental appendectomies and patients with perforated appendicitis. An equal number of pediatric patients undergoing laparoscopic and open procedures were included in the analysis to avoid bias, because most of the laparoscopic appendectomies were performed in the adult patient population (age of more than 16 years). A University Medical Center, a Veterans Administration and two community hospitals were the settings. Patients undergoing laparoscopic appendectomy (n = 54) had an average age of 25.7 +/- 1.5 (range of six to 59 years). These patients were compared with 121 patients undergoing open appendectomy whose average age was 23.7 +/- 1.8 (range of three to 83 years). The race and gender distribution were similar in the two groups. Traditional open appendectomy was compared with a group of patients undergoing laparoscopic appendectomy. Variables evaluated were operating room time, number of patients who reported nausea, days until patient tolerated a regular diet, days of hospitalization, postoperative pain medication and wound infection rate. Results are expressed as the mean plus or minus standard error of the mean. Analysis of variance was used to compute continuous variables and Fischer's exact test was used for discrete variables. The laparoscopic approach was attempted in 61 patients and completed in 54 patients. Open appendectomy was performed upon 121 patients. Nineteen patients (18 who underwent open operation and one patient who underwent laparoscopic operation) were excluded from

    OBJECTIVE: The authors determined whether there was an advantage to laparoscopic appendectomy when compared with open appendectomy. SUMMARY/BACKGROUND DATA: The advantages of laparoscopic appendectomy versus open appendectomy were questioned because the recovery from open appendectomy is brief. METHODS: From January 15, 1992 through January 15, 1993, 75 patients older than 9 years were entered into a study randomizing the choice of operation to either the open or the laparoscopic technique. Statistical comparisons were performed using the Wilcoxon test. RESULTS: Thirty-seven patients were assigned to the open appendectomy group and 38 patients were assigned to the laparoscopic appendectomy group. Two patients were converted intraoperatively from laparoscopic appendectomies to open procedures. Thirty-one patients (81%) in the open group had acute appendicitis, as did 32 patients (84%) in the laparoscopic group. Mean duration of surgery was 65 minutes for open appendectomy and 87 minutes for laparoscopic appendectomy (p < 0.001). There were no statistically significant differences in length of hospitalization, interval until resumption of a regular diet, or morbidity. Duration of both parenteral and oral analgesic use favored laparoscopic appendectomy (2.0 days versus 1.2 days, and 8.0 days versus 5.4 days, p < 0.05). All patients were instructed to return to full activities by 2 weeks postoperatively. This occurred at an average of 25 days for the open appendectomy group versus 14 days for the laparoscopic appendectomy group (p < 0.001). CONCLUSIONS: Patients who underwent laparoscopic appendectomies have a shorter duration of analgesic use and return to full activities sooner postoperatively when compared with patients who underwent open appendectomies. The authors consider laparoscopic appendectomy to be the procedure of choice in patients with acute appendicitis. PMID:8203983

    1992-12-01

    After laparoscopic exploration of the common bile duct, or when a patient has acute cholecystitis, the cystic duct is sometimes edematous and too large to be ligated safely with an Endoclip. In such cases, ligation of the cystic duct with an Endoloop offers a solution to the problem. The standard technique for application of an Endoloop consists of dividing the cystic duct and then applying the Endoloop. This becomes more difficult if, after the cystic duct is divided, loss of traction on the common bile duct results in retraction of the divided cystic stump outside of the laparoscopic field of view. To avoid this difficulty, the authors apply an Endoloop with the grasping forceps on the cystic duct before the duct is divided so that it cannot retract from operative view and for this task developed an instrument that allows simultaneous introduction of both grasping forceps and the Endoloop through a single port.

    Leiomyosarcoma is a rare malignant tumor originating from the smooth muscular tissue in any part of the organism. The only therapy is its complete removal. We describe herein the operative treatment of a retroperitoneal leiomyosarcoma with gasless laparoscopic complete removal. The procedure was successfully performed in a consenting woman with an abdominal mass. Gasless laparoscopic removal was performed with a mechanical retractor (Laparolift, Origin Medsystem Inc.), obviating the creation of the pneumoperitoneum and of the sealed environment. The technique is a simple, safe, and effective surgical method. Gasless technique guarantees a clear vision, makes possible continuous suction of smoke and fluids, and allows the use of conventional instruments and easy management of suturing. The present case has proved to be another abdominal procedure that can be carried out with all the advantages of gasless miniinvasive surgery.

    Gastric diverticula are rare and usually asymptomatic. This report, however, describes two examples of symptomatic gastric diverticula successfully treated by laparoscopic resection. Both patients were male and in their sixth decade of life. One patient was relatively healthy with no past medical history, whereas the other patient had chronic pain issues and at presentation was also undergoing evaluation for hyperaldosteronism. The patients presented with gastrointestinal symptoms, including nausea, emesis, abdominal pain, and change in bowel function. In both cases, a gastric diverticulum was identified by CT scan, and precise anatomic position was determined by upper endoscopy. After discussion with the treating teams, including a gastroenterologist and surgeon, surgical treatment and resection was elected. Successful laparoscopic removal was accomplished in both patients, and they were discharged home after tolerating liquid diets. Both patients reported resolution of their abdominal symptoms at follow-up. PMID:24680154

    Today, laparoscopic cholecystectomy is the method of choice for treatment of symptomatic gallbladder disorders. It minimizes effects of the operation that are independent of the gallbladder, such as trauma to the abdominal wall and other soft tissue. The surgical wounds were even smaller when 2-mm trocars were used. Laparoscopic cholecystectomy using 2-mm instruments was performed in a consecutive series of 14 patients with symptomatic gallstones. The procedure was completed in 12 cases, with conversion to open surgery in two cases. Intraoperative cholangiography was always performed. The postoperative course was always uneventful. The cosmetic effect was highly satisfactory. The procedure using 2-mm instruments could be indicated in selected patients with uncomplicated gallstone disease.

    The purpose of this study was to evaluate the results of a laparoscopic transabdominal preperitoneal (TAPP) approach to inguinal hernia repair which dissected the entire inguinal floor and repaired the indirect, direct, and femoral areas in all patients without tension. In our series, 183 patients had 205 hernia repairs and were followed for more than 6 months. Of this group, 128 hernias were indirect, 55 direct, 22 pantaloon, 26 recurrent, and 22 bilateral. All 12 females and the first 11 males had a single-buttress repair with polypropylene mesh. The other 160 male patients had a double-buttress repair. With median follow-up of 12 months, ranging from 6 to 21 months, no recurrences were found. Patients returned to normal activity in an average of 1 week. Dissection and buttressing of the entire inguinal floor with mesh appeared to solve the problem of early recurrence first seen in laparoscopic herniorrhaphy.

    The stomach is the preferred augmentation option for a contracted bladder in a patient with renal failure. A 49-year-old female presented with right solitary functioning kidney with tuberculous lower ureteric stricture and contracted bladder. Her creatinine was 2.8 mg%. By laparoscopic approach, right gastroepiploic artery based gastric flap was isolated using staplers and used for augmentation and ureteric replacement. At 6-month follow-up, her creatinine was 1.9 mg%, and bladder capacity was 250 ml. She had mild hematuria, which settled with proton pump inhibitors. Laparoscopic gastrocystoplasty is feasible and effective augmentation option in those with renal failure, giving the benefits of minimally invasive approach. PMID:28197034

    The incidence of uterus didelphys is around 3/10,000 women. It is a class III Müllerian duct anomaly resulting from a complete non-fusion of the paired Müllerian ducts between the 12th and 16th weeks of gestation. Although the prevalence of cervical insufficiency in women with uterus didelphys is unknown, the incidence of cervical insufficiency in women with Müllerian anomalies has been reported as high as 30%. We present a case of successful pregnancy outcome following a laparoscopic transabdominal cerclage in a woman with uterus didelphys and cervical insufficiency. The case demonstrates that laparoscopic transabdominal cerclage can be performed successfully in women with uterus didelphys and a satisfactory obstetric outcome can be achieved.

    Clinically significant carbon dioxide embolism is a rare but potentially fatal complication of anesthesia administered during laparoscopic surgery. Its most common cause is inadvertent injection of carbon dioxide into a large vein, artery or solid organ. This error usually occurs during or shortly after insufflation of carbon dioxide into the body cavity, but may result from direct intravascular insufflation of carbon dioxide during surgery. Clinical presentation of carbon dioxide embolism ranges from asymptomatic to neurologic injury, cardiovascular collapse or even death, which is dependent on the rate and volume of carbon dioxide entrapment and the patient's condition. We reviewed extensive literature regarding carbon dioxide embolism in detail and set out to describe the complication from background to treatment. We hope that the present work will improve our understanding of carbon dioxide embolism during laparoscopic surgery.

    Introduction: Adhesions are the reason for bowel obstruction in 80% of the cases. In well selected patients the adhesive ileus laparoscopic treatment has multiple advantages which include the shorter hospitalization period, earlier food taking, and less postoperative morbidity rate. Case report: Here we have a patient in the age of 35 hospitalized at the clinic due to occlusive symptoms. Two years before an opened appendectomy had been performed on him. He underwent the treatment of exploration laparoscopy and laparoscopic adhesiolysis. Dilated small bowel loops connected with the anterior abdominal wall in the ileocecal region by adhesions were found intraoperatively and then resected harmonically with scalpel. One strangulation around which a small bowel loop was wrapped around was found and dissected. Postoperative course was normal. PMID:27041815

    We report a case of minimally invasive surgery in the management of metastasis to the spleen. A 67-year-old male patient with possible splenic soft tissue melanoma metastasis was referred to our hospital. He had a history of an excised soft tissue melanoma from his back eight months earlier, and the control abdominal computer tomography (CT) scan revealed a hypodense spleen lesion. The patient underwent laparoscopic surgery to diagnose and treat the splenic lesion. The splenectomy was performed and the histological examination revealed a melanoma. The patient had a good postoperative course and was discharged on the second postoperative day. On his 12-month follow-up there was no sign of recurrence. The laparoscopic approach is a safe and effective alternative for treatment of splenic metastases. PMID:19547681

    Laparoscopy reduces patient trauma but eliminates the surgeon's ability to directly view and touch the surgical environment. Although current robot-assisted laparoscopy improves the surgeon's ability to manipulate and visualize the target organs, the instruments and cameras remain constrained by the entry incision. This limits tool tip orientation and optimal camera placement. This article focuses on developing miniature in vivo robots to assist surgeons during laparoscopic surgery by providing an enhanced field of view from multiple angles and dexterous manipulators not constrained by the abdominal wall fulcrum effect. Miniature camera robots were inserted through a small incision into the insufflated abdominal cavity of an anesthetized pig. Trocar insertion and other laparoscopic tool placements were then viewed with these robotic cameras. The miniature robots provided additional camera angles that improved surgical visualization during a cholecystectomy. These successful prototype trials have demonstrated that miniature in vivo robots can provide surgeons with additional visual information that can increase procedural safety.

  9. Diagnostic and Therapeutic Advances: Distal Symmetric Polyneuropathy

    Importance Peripheral neuropathy is a highly prevalent and morbid condition affecting 2–7% of the population. Patients frequently suffer from pain and are at risk of falls, ulcerations, and amputations. We aimed to review recent diagnostic and therapeutic advances in peripheral neuropathy in distal symmetric polyneuropathy, the most common subtype of peripheral neuropathy. Observations and Advances Current evidence supports limited routine laboratory testing in patients with distal symmetric polyneuropathy. Patients without a known cause should have a complete blood count, comprehensive metabolic panel, B12, serum protein electrophoresis with immunofixation, fasting glucose, and a glucose tolerance test. The presence of atypical features such as asymmetry, non-length-dependence, motor predominance, acute or subacute onset, and/or prominent autonomic involvement should prompt a consultation with a neurologist or neuromuscular specialist. Electrodiagnostic tests and magnetic resonance imaging of the neuroaxis are the main drivers of the cost of the diagnostic evaluation, but evidence supporting their use is lacking. Strong evidence supports the use of tricyclic antidepressants, serotonin and norepinephrine reuptake inhibitors, and voltage-gated calcium channel ligands in the treatment of neuropathic pain. More intensive glucose control substantially reduces the incidence of distal symmetric polyneuropathy in patients with type 1 diabetes, but does not in type 2 diabetes. Conclusions and Relevance The opportunity exists to improve guideline concordant testing in distal symmetric polyneuropathy patients. Moreover, the role of electrodiagnostic tests needs to be further defined, and interventions to reduce magnetic resonance imaging use in this population are needed. Even though several efficacious medications exist for neuropathic pain treatment, pain is still under-recognized and undertreated. New disease modifying medications are needed to prevent and treat

    Hereditary spherocytosis (HS) and distal renal tubular acidosis (dRTA), although distinct entities, share the same protein i.e. the anion exchanger1 (AE1) protein. Despite this, their coexistence has been rarely reported. We hereby describe the largest family to date with co-existence of dRTA and HS and discuss the molecular basis for the co-inheritance of these conditions.

  11. Distal biceps tendon injuries: diagnosis and management.

    PubMed

    Ramsey, M L

    1999-01-01

    Rupture of the distal biceps tendon occurs most commonly in the dominant extremity of men between 40 and 60 years of age when an unexpected extension force is applied to the flexed arm. Although previously thought to be an uncommon injury, distal biceps tendon ruptures are being reported with increasing frequency. The rupture typically occurs at the tendon insertion into the radial tuberosity in an area of preexisting tendon degeneration. The diagnosis is made on the basis of a history of a painful, tearing sensation in the antecubital region. Physical examination demonstrates a palpable and visible deformity of the distal biceps muscle belly with weakness in flexion and supination. The ability to palpate the tendon in the antecubital fossa may indicate partial tearing of the biceps tendon. Plain radiographs may show hypertrophic bone formation at the radial tuberosity. Magnetic resonance imaging is generally not required to diagnose a complete rupture but may be useful in the case of a partial rupture. Early surgical reattachment to the radial tuberosity is recommended for optimal results. A modified two-incision technique is the most widely used method of repair, but anterior single-incision techniques may be equally effective provided the radial nerve is protected. The patient with a chronic rupture may benefit from surgical reattachment, but proximal retraction and scarring of the muscle belly can make tendon mobilization difficult, and inadequate length of the distal biceps tendon may necessitate tendon augmentation. Postoperative rehabilitation must emphasize protected return of motion for the first 8 weeks after repair. Formal strengthening may begin as early as 8 weeks, with a return to unrestricted activities, including lifting, by 5 months.

    Fractures of distal radius account for up to 20% of all fractures treated in emergency department. Initial assessment includes a history of mechanism of injury, associated injury and appropriate radiological evaluation. Treatment options include conservative management, internal fixation with pins, bridging and non-bridging external fixation, dorsal or volar plating with/without arthroscopy assistance. However, many questions regarding these fractures remain unanswered and good prospective randomized trials are needed. PMID:25657938

    Studies detailing differences in positive surgical margin among open retropubic radical prostatectomy, laparoscopic radical prostatectomy, and robotic-assisted laparoscopic radical prostatectomy are lacking. A retrospective review of all prostatectomies with positive surgical margin performed at our center in 2007 disclosed 99 cases, 6 (5%) of which were reinterpreted cases as having negative margins. Ninety-three cases were, therefore, included, corresponding to 37 retropubic radical prostatectomies, 19 laparoscopic radical prostatectomies, and 37 robotic-assisted laparoscopic radical prostatectomies. The relationship of positive surgical margin characteristics to clinicopathologic parameters and biochemical recurrence was assessed. The most commonly found positive surgical margin site was the apex/distal third in all groups (62% retropubic prostatectomies, 79% laparoscopic prostatectomies, 60% robotic-assisted prostatectomies). Total linear length of positive surgical margin sites was significantly correlated with preoperative prostate-specific antigen, preoperative prostate-specific antigen density, pT stage, and tumor volume (P ≤ .001). We found no significant differences among the 3 groups with respect to total linear length, number of foci, laterality, or location of positive surgical margin. The rate of biochemical recurrence was also comparable in the 3 groups. On univariate analyses, biochemical recurrence was significantly associated with preoperative prostate-specific antigen values, preoperative prostate-specific antigen density, Gleason score, number of positive surgical margins, and total linear length of positive surgical margin (P ≤ .02). Only preoperative prostate-specific antigen density and number of positive surgical margin foci were statistically significant (P ≤ .03) independent predictors of biochemical recurrence. We found no significant difference in positive surgical margin characteristics or biochemical recurrence among the 3

    Bariatric surgery improves non-alcoholic fatty liver disease (NAFLD). Our aim was to investigate the potential role of ghrelin isoforms in the resolution of hepatic steatosis after sleeve gastrectomy, a restrictive bariatric surgery procedure, in diet-induced obese rats. Male Wistar rats (n = 161) were subjected to surgical (sham operation and sleeve gastrectomy) or dietary interventions [fed ad libitum a normal (ND) or a high-fat (HFD) diet or pair-fed]. Obese rats developed hepatosteatosis and showed decreased circulating desacyl ghrelin without changes in acylated ghrelin. Sleeve gastrectomy induced a dramatic decrease of desacyl ghrelin, but increased the acylated/desacyl ghrelin ratio. Moreover, sleeve gastrectomy reduced hepatic triglyceride content and lipogenic enzymes Mogat2 and Dgat1, increased mitochondrial DNA amount and induced AMPK-activated mitochondrial FFA β-oxidation and autophagy to a higher extent than caloric restriction. In primary rat hepatocytes, the incubation with both acylated and desacyl ghrelin (10, 100 and 1,000 pmol/L) significantly increased TG content, triggered AMPK-activated mitochondrial FFA β-oxidation and autophagy. Our data suggest that the decrease in the most abundant isoform, desacyl ghrelin, after sleeve gastrectomy contributes to the reduction of lipogenesis, whereas the increased relative acylated ghrelin levels activate factors involved in mitochondrial FFA β-oxidation and autophagy in obese rats, thereby ameliorating NAFLD.

    AIM: To investigate the cooperative laparoscopic and endoscopic techniques used for the resection of upper gastrointestinal tumors. METHODS: A systematic research of the literature was performed in PubMed for English and French language articles about laparoscopic and endoscopic cooperative, combined, hybrid and rendezvous techniques. Only original studies using these techniques for the resection of early gastric cancer, benign tumors and gastrointestinal stromal tumors of the stomach and the duodenum were included. By excluding case series of less than 10 patients, 25 studies were identified. The study design, number of cases, tumor pathology size and location, the operative technique name, the endoscopy team and surgical team role, operative time, type of closure of visceral wall defect, blood loss, complications and length of hospital stay of these studies were evaluated. Additionally all cooperative techniques found were classified and are presented in a systematic approach. RESULTS: The studies identified were case series and retrospective cohort studies. A total of 706 patients were operated on with a cooperative technique. The tumors resected were only gastrointestinal stromal tumors (GIST) in 4 studies, GIST and various benign submucosal tumors in 22 studies, early gastric cancer (pT1a and pT1b) in 6 studies and early duodenal cancer in 1 study. There was important heterogeneity between the studies. The operative techniques identified were: laparoscopic assisted endoscopic resection, endoscopic assisted wedge resection, endoscopic assisted transgastric and intragastric surgery, laparoscopic endoscopic cooperative surgery (LECS), laparoscopic assisted endoscopic full thickness resection (LAEFR), clean non exposure technique and non-exposed endoscopic wall-inversion surgery (NEWS). Each technique is illustrated with the roles of the endoscopic and laparoscopic teams; the indications, characteristics and short term results are described. CONCLUSION: Along with

  17. Distal Embolic Protection for Renal Arterial Interventions

    2008-01-15

    Distal or embolic protection has intuitive appeal for its potential to prevent embolization of materials generated during interventional procedures. Distal protection devices (DPDs) have been most widely used in the coronary and carotid vascular beds, where they have demonstrated the ability to trap embolic materials and, in some cases, to reduce complications. Given the frequency of chronic kidney disease in patients with renal artery stenosis undergoing stent placement, it is reasonable to propose that these devices may play an important role in limiting distal embolization in the renal vasculature. Careful review of the literature reveals that atheroembolization does occur during renal arterial interventions, although it often goes undetected. Early experience with DPDs in the renal arteries in patients with suitable anatomy suggests retrieval of embolic materials in approximately 71% of cases and renal functional improvement/stabilization in 98% of cases. The combination of platelet inhibition and a DPD may provide even greater benefit. Given the critical importance of renal functional preservation, it follows that everything that can be done to prevent atheroembolism should be undertaken including the use of DPDs when anatomically feasible. The data available at this time support a beneficial role for these devices.

  18. Triplane fracture of the distal radius.

    2006-07-01

    A case of triplane fracture of the distal radius is reported in a 13-year-old boy. This exceptional fracture showed displacement, and was healed by closed reduction and 6 weeks of external immobilization. Eighteen months later, the patient showed complete physeal arrest of the distal radius, with radio-ulnar length discrepancy but without any repercussion on wrist mobility. The patient was declared asymptomatic 3 years after the injury. Prompt, physiological physeal arrest reduces the potential of growth deformity. These fractures must be treated conservatively by closed reduction (if displacement exists) and external immobilization, just like a normal one-plane fracture. We may suppose that final radio-ulnar discrepancy could lead to a painful and symptomatic ulno-carpal conflict in adult life. The following characteristics can be associated with this rare fracture: (1) occurrence close to the end of the growth period, as in other types of triplane fractures; (2) evolution towards partial or complete growth arrest of the physis, not requiring treatment and (3) stability of the fracture after closed reduction. In the present case, as in the other reported cases, it may also be added that orthopaedic treatment has been the rule, in contrast with triplane fractures occurring in the distal tibia, in which surgical treatment is indicated.

  19. Novel topical therapies for distal colitis.

    Distal colitis (DC) can be effectively treated with topical 5ASA agents. Suppositories target the rectum while enemas can reliably reach the splenic flexure. Used in combination with oral 5ASAs, the control of the inflammation is even more effective. Unfortunately, resistant DC does occur and can be extremely challenging to manage. In these patients, the use of steroids, immunosuppressants and the anti-tumor necrosis factor α agents are often required. These, however, can be associated with systemic side effects and are not always effective. The investigation of new topical therapeutic agents is thus required as they are rarely associated with significant blood drug levels and side effects are infrequent. Some of the agents that have been proposed for use in resistant distal colitis include butyrate, cyclosporine and nicotine enemas as well as tacrolimus suppositories and tacrolimus, ecabet sodium, arsenic, lidocaine, rebamipide and Ridogrel(®) enemas. Some of these agents have demonstrated impressive results but the majority of the agents have only been assessed in small open-labelled patient cohorts. Further work is thus required with the investigation of promising agents in the context of randomized double-blinded placebo controlled trials. This review aims to highlight those potentially effective therapies in the management of resistant distal colitis and to promote interest in furthering their investigation.

    The objective of this report was to develop a case definition of "distal symmetrical polyneuropathy" to standardize and facilitate clinical research and epidemiological studies. A formalized consensus process was employed to reach agreement after a systematic review and classification of evidence from the literature. The literature indicates that symptoms alone have relatively poor diagnostic accuracy in predicting the presence of polyneuropathy; signs are better predictors of polyneuropathy than symptoms; and single abnormalities on examination are less sensitive than multiple abnormalities in predicting the presence of polyneuropathy. The combination of neuropathic symptoms, signs, and electrodiagnostic findings provides the most accurate diagnosis of distal symmetrical polyneuropathy. A set of case definitions was rank ordered by likelihood of disease. The highest likelihood of polyneuropathy (useful for clinical trials) occurs with a combination of multiple symptoms, multiple signs, and abnormal electrodiagnostic studies. A modest likelihood of polyneuropathy (useful for field or epidemiological studies) occurs with a combination of multiple symptoms and multiple signs when the results of electrodiagnostic studies are not available. A lower likelihood of polyneuropathy occurs when electrodiagnostic studies and signs are discordant. For research purposes, the best approach for defining distal symmetrical polyneuropathy is a set of case definitions rank ordered by estimated likelihood of disease. The inclusion of this formalized case definition in clinical and epidemiological research studies will ensure greater consistency of case selection.

    Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant (both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments (1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of laparoscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.

    1994-01-16

    Intraoperative cholangiography (IC) in laparoscopic cholecystectomy is a controversial issue. According to traditional teaching, the purpose of cholangiography in gallbladder surgery is to discover previously undiscovered common bile duct stones. This examination was extremely important in the era before ERCP. IC enabled surgeons to find stones and remove them at the same operation. With progress in ERCP, the importance of intraoperative cholangiography has diminished. A stone missed during surgery can most often be dealt with by the less invasive ERCP and papillotomy. There has been a difference of opinion in the literature as to whether to perform cholangiography routinely during gallbladder operations or only in cases in which there is a specific indication, such as an enlarged common bile duct, a history of pancreatitis, or elevated enzymes. Routine operative cholangiography prolongs operative time and carries its own inherent risks, such as injury to the bile ducts. The likelihood of stones is not high and over-diagnosis of stones would result in unwarranted common bile duct exploration and the danger of complications from the procedure. The tendency today is towards a more selective approach. In this era of laparoscopic gallbladder surgery, the controversy has come to the fore again, and there is now an additional aspect. In laparoscopic gallbladder surgery there is greater significance to the "road map" provided by X-rays. We rely mainly on the visual sense and have forgone the tactile sense. Therefore, any added visual input in this operation helps avoid the danger of injuring the main bile ducts. It is our contention that the indications for operative cholangiography in laparoscopic cholecystectomy should again be broadened.

    ABSTRACT Vascular injury in accidental punctures may occur in large abdominal vessels, it is known that 76% of injuries occur during the development of pneumoperitoneum. The aim of this video is to demonstrate two cases of vascular injury occurring during access in laparoscopic urologic surgery. The first case presents a 60-year old female patient with a 3cm tumor in the superior pole of the right kidney who underwent a laparoscopic partial nephrectomy. After the Verres needle insertion, output of blood was verified. During the evaluation of the cavity, a significant hematoma in the inferior vena cava was noticed. After the dissection, a lesion in the inferior vena cava was identified and controlled with a prolene suture, the estimated bloos loss was 300ml. The second case presents a 42-year old female live donor patient who had her right kidney selected to laparoscopic live donor nephrectomy. After the insertion of the first trocar, during the introduction of the 10mm scope, an active bleeding from the mesentery was noticed. The right colon was dissected and an inferior vena cava perforation was identified; a prolene suture was used to control the bleeding, the estimated blood loss was 200mL, in both cases the patients had no previous abdominal surgery. Urologists must be aware of this uncommon, serious, and potentially lethal complication. Once recognized and in the hands of experienced surgeons, some lesions may be repaired laparoscopically. Whenever in doubt, the best alternative is the immediate conversion to open surgery to minimize morbidity and mortality. PMID:28124541

    Postoperative ascites is a very rare complication of laparoscopic surgery. Significant iatrogenic injuries to the bowel, the urinary tract, and the lymphatic system should be excluded promptly to avoid devastating results for the patient. In some cases, in spite of investigating patients extensively, no definitive causative factor for the accumulation of fluid can be identified. In such cases, idiopathic allergic or inflammatory reaction of the peritoneum may be responsible for the development of ascites. We present a case of ascites of an unknown origin in a young female patient following a laparoscopic appendicectomy. PMID:24822146

    Spontaneous external haemorrhage from the umbilical varix is an extremely rare complication of portal hypertension. Bleeding is usually into the peritoneal cavity and the treatment involves urgent laparotomy and ligation of the bleeding varices. We describe a cirrhotic 38-year-old man who presented with spontaneous external haemorrhage from the umbilical varix which was successfully managed laparoscopically by in-situ distal clipping and proximal transcutaneous ligation of the recanalised paraumbilical veins. We therefore feel that laparoscopy can be safely and effectively employed to control external haemorrhage from the umbilical varix associated with liver cirrhosis. This novel technique can help avoid a laparotomy and also help preserve the umbilicus.

    Background: The aim of this study was to compare peri-operative results of laparoscopic supracervical hysterectomy (LSH) with those of laparoscopic total hysterectomy (TLH). Methods: A retrospective cohort study was conducted at the Department of Gynecology at a teaching hospital. A group of 157 patients who underwent TLH was compared with a group of 157 patients who underwent LSH with or without bilateral salpingo-oophorectomy (BSO). Both groups had similar baseline characteristics and comparable surgical indications. Results: We reviewed our 7-year experience with laparoscopic hysterectomies performed at our department between October 2000 and November 2007. The similarities between patient characteristics were tested by using Wilcoxon Rank Sum Statistics. Patient and surgery characteristics as well as surgery outcomes were analyzed with descriptive statistics showing medians and 95% CIs. Women who underwent LSH had a shorter operation time compared with women in the TLH group (100 min vs. 110 min). Major complication rates were higher in the TLH group than in the LSH group (4.5% vs. 1.3%). Minor complication rates were 13.3% in the TLH group compared with 13.4% in the LSH group. Conclusions: Our data and experience provide specific information about the perioperative performance of LSH compared with TLH. In our experience, LSH proved to be a valid alternative to TLH in the absence of specific indications for TLH. Adequate counseling concerning the risk of cyclical bleeding and reoperation is mandatory. PMID:19793479

    Laparoscopic surgery has become a widely used procedure with many advantages compared to conventional laparotomy. Although rare, this technique is not entirely absent from clinical hazards and particularly thromboembolic events. This complication is due to activation of the coagulation cascade, as well as factors that may cause alterations in blood rheology. Apart from high hematocrit, presence of abnormal proteins and elevated fibrinogen level, the type of anesthesia, temperature, and increased intra-abdominal pressure following CO(2) insufflation may affect blood viscosity. Therefore, the objective of the study was to compare rheological events in 17 patients undergoing laparoscopic surgery to those in 15 patients who underwent laparotomy. Both groups of patients did not show any complications during the early and late post-operative period. The values of whole blood viscosity in patients undergoing laparoscopy did not differ from those in patients treated by laparotomy. A slight, although significant decrease in plasma viscosity and red blood cell aggregation was observed in patients who underwent laparotomy. The results suggest that the benefits of laparoscopic surgery in the present series were not affected by alterations in blood and plasma viscosity, as well as in red blood cell aggregation.

    Persistent mullerian duct syndrome (PMDS), characterized by the presence of mullerian structures in a virilized male, frequently presents as undescended testis, either intraabdominal or within a hernial sac. We describe a 10-month-old infant with PMDS successfully managed by the laparoscopic approach. At the age of 1.5 months, the patient presented with a left inguinal hernia and bilateral nonpalpable gonads in another center and underwent left inguinal exploration. The uterus and a gonadlike structure along with the hernia sac were found in the inguinal canal. Left inguinal herniotomy was performed after reduction of the uterus and gonadlike structure. No gonadal biopsy was obtained. The patient was further investigated in the same center. His karyotype was 46,XY. Magnetic resonance imaging of the abdomen and pelvis revealed a uterinelike structure posterior to the urinary bladder, but neither testis nor ovaries were visualized. At 10 months of age, he was referred to our department for further management. A laparoscopic single-stage orchiopexy was performed. Both testes were identified and brought to the scrotum by splitting the uterus in the midline and then bringing the testes with the vas and attached uterine tissue into the scrotum. The aim of placement of well-vascularized testes in the scrotum was achieved as confirmed on follow-up color Doppler ultrasound study 6 months postoperatively, which showed normal vascularity. Laparoscopic surgical techniques for this condition are also discussed.

    Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of gastric contents into the esophagus leads to troublesome symptoms and/or complications. Heartburn is the cardinal symptom, often associated with regurgitation. In patients with endoscopy-negative heartburn refractory to proton pump inhibitor (PPI) therapy and when the diagnosis of GERD is in question, direct reflux testing by impedance-pH monitoring is warranted. Laparoscopic fundoplication is the standard surgical treatment for GERD. It is highly effective in curing GERD with a 80% success rate at 20-year follow-up. The Nissen fundoplication, consisting of a total (360°) wrap, is the most commonly performed antireflux operation. To reduce postoperative dysphagia and gas bloating, partial fundoplications are also used, including the posterior (Toupet) fundoplication, and the anterior (Dor) fundoplication. Currently, there is consensus to advise laparoscopic fundoplication in PPI-responsive GERD only for those patients who develop untoward side-effects or complications from PPI therapy. PPI resistance is the real challenge in GERD. There is consensus that carefully selected GERD patients refractory to PPI therapy are eligible for laparoscopic fundoplication, provided that objective evidence of reflux as the cause of ongoing symptoms has been obtained. For this purpose, impedance-pH monitoring is regarded as the diagnostic gold standard.

    Stump appendicitis is a rare delayed complication of appendectomy. The delay in diagnosis is usually because of a prior history of appendectomy. We report a case of stump appendicitis diagnosed pre-operatively with a computerized tomography (CT) scan after laparoscopic appendectomy. An 18-year-old male presented with a one-week history of lower abdominal pain, nausea and vomiting. He had a history of laparoscopic appendectomy for acute appendicitis. Physical examination revealed tenderness and guarding in the lower abdomen. CT scan showed free pelvic fluid with a tubular structure of about 2.5 cm in length and 0.78 cm in diameter located posterior to the ileo-cecal junction. Laparoscopic exploration confirmed the findings. A residual appendiceal stump was found and dissected from the adhesion and removed. Histopathology showed a residual appendix with transmural neutrophilic infiltration associated with multifocal hemorrhagic necrosis. The postoperative period was uneventful. The diagnosis of stump appendicitis can be challenging. CT scan has proven to be a useful tool for the diagnosis of this rare condition.

    Abstract Retrograde approach (“fundus first”) is often used in open surgery, while in laparoscopic cholecystectomy (LC) is less frequent. LC, with antegrade access, is done by putting in traction the infundibulum and going up to the fundus before to clip the cystic. Our study analyzes a number of surgical procedures performed by experienced surgeons in laparoscopy. From 2002 to 2015, 1740 laparoscopic cholecystectomies were performed at our Institution. The operative procedure performed since 2002 consists of the incision of the visceral peritoneum from the infundibulum away from Calot’s triangle along the gallbladder bed up to the fundus. Then it continues from the fundus up to the infundibulum. Results: There were no bile duct injuries. Average operative time was 40 min. 22 conversions to an open procedure (1.3%) occurred, in cases of acute cholecystitis and cirrhotic patient. Postoperative stay was mean 2 days with no delayed sequelae on follow up. Conclusions: gallbladder antegrade dissection for laparoscopic cholecystectomy can reduce the time of surgery and is an easier technique to perform. Therefore, it can be proposed as the standard procedure and not only be used for difficult cholecystectomies. PMID:28352832

  19. Endoscopic and laparoscopic treatment of gastroesophageal reflux.

    2010-04-01

    Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

    Background and Objectives: A Spigelian hernia is a rare type of hernia that occurs through a defect in the anterior abdominal wall adjacent to the linea semilunaris. Estimation of its incidence has been reported as 0.12% of all abdominal wall hernias. Traditionally, the method of repair has been an open approach. Herein, we discuss a series of laparoscopic repairs. Methods: Case series and review of the literature. Cases: Three patients are presented. All were evaluated and taken to surgery initially for a different disease process, and all were incidentally found to have a spigelian hernia. These patients underwent laparoscopic repair of their hernias; 2 were repaired intraperitoneally and one was repaired totally extraperitoneally. Two patients initially underwent a mesh repair, while the third had an attempted primary repair. Conclusions: There is evidence that supports the use of laparoscopy for both diagnosis and repair of spigelian hernias. There are also reports of successful repairs both primarily and with mesh. In our experience with the preceding 3 patients, we found that laparoscopic repair of incidentally discovered spigelian hernias is a viable option, and we also found that implantation of mesh, when possible, resulted in satisfactory results and no recurrence.

  1. The effect of vertical sleeve gastrectomy on a rat model of polycystic ovarian syndrome.

    2011-10-01

    Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder of women of reproductive age. Although some of the primary symptoms of PCOS are reproductive abnormalities, including hyperandrogenism, menstrual dysfunction, and hirsutism, other metabolic disturbances are also common, including obesity and insulin resistance. Women with PCOS who have undergone weight-loss bariatric surgery have reported surprising postoperative benefits beyond weight loss, including resolution of menstrual dysfunction and improvement of hirsutism. Here, we use a chronic dihydrotestosterone (DHT) exposure model of PCOS in female rats and investigate the efficacy of a specific type of bariatric surgery, namely vertical sleeve gastrectomy (VSG), to resolve the reproductive and metabolic disturbances induced by DHT treatment. We find that VSG causes loss of body weight and body fat in DHT-treated rats but does not improve glucose tolerance or restore estrous cyclicity. Although human PCOS patients have shown decreased androgen levels after bariatric surgery, the chronic nature of DHT administration in this rat model both before and after VSG renders this effect impossible in this case. Therefore, the lack of improvement in glucose tolerance and estrous cyclicity may implicate a direct effect of androgen knockdown as a mechanism for the improvements seen in human PCOS patients after bariatric surgery. In addition, the dissociation of body weight loss without improved glucose tolerance suggests that glucose intolerance may be a body weight-independent phenomenon in women with PCOS.

    Obesity has profound negative consequences on female reproduction as well as on the metabolic health of offspring. Bariatric surgery is the most effective method for sustained weight loss. A critical question is whether bariatric surgery can reverse the deleterious effects of obesity on both female reproduction and subsequent offspring. Vertical sleeve gastrectomy (VSG) is a bariatric procedure rapidly growing in popularity because it provides weight loss and other metabolic benefits that are comparable to those offered by the more complicated Roux-en-Y gastric bypass (RYGB). Female rats rendered obese on a high-fat diet (HFD) underwent either VSG or sham surgery. Like their male counterparts, females had significant metabolic improvements including reduced adiposity and improved glucose tolerance. After VSG, female rats showed a more normal reproductive cycle. Despite these maternal benefits, the offspring of dams receiving VSG were born smaller and lighter than offspring of control dams that underwent sham surgery. When maintained on an HFD after puberty, these adult offspring had a greater propensity to develop glucose intolerance and increased adiposity than the offspring of lean mothers or obese mothers who underwent sham surgery. These data suggest that weight loss alone by obese mothers is not sufficient to reverse the deleterious effects of an HFD and obesity on their offspring. PMID:23966301

    Bariatric surgery is currently the most effective treatment for obesity. Vertical sleeve gastrectomy (VSG), a commonly applied bariatric procedure, involves surgically incising most of the volume of the stomach. In humans, partial loss of melanocortin receptor-4 (MC4R) activity is the most common monogenic correlate of obesity regardless of lifestyle. At present it is unclear whether genetic alteration of MC4R signaling modulates the beneficial effects of VSG. Following VSG, we analyzed body weight, food intake, glucose sensitivity, and macronutrient preference of wild-type and MC4R-deficient (Mc4r(+/-) and Mc4r(-/-)) rats compared with sham-operated controls. VSG reduced body weight and fat mass and improved glucose metabolism and also shifted preference toward carbohydrates and away from fat. All of this occurred independently of MC4R activity. In addition, MC4R was resequenced in 46 human subjects who underwent VSG. We observed common genetic variations in the coding sequence of MC4R in five subjects. However, none of those variations appeared to affect the outcome of VSG. Taken together, these data suggest that the beneficial effect of VSG on body weight and glucose metabolism is not mediated by alterations in MC4R activity.

    AIM: To evaluate the long-term clinical and oncological outcomes of laparoscopic rectal resection (LRR) and the impact of conversion in patients with rectal cancer. METHODS: An analysis was performed on a prospective database of 633 consecutive patients with rectal cancer who underwent surgical resection. Patients were compared in three groups: Open surgery (OP), laparoscopic surgery, and converted laparoscopic surgery. Short-term outcomes, long-term outcomes, and survival analysis were compared. RESULTS: Among 633 patients studied, 200 patients had successful laparoscopic resections with a conversion rate of 11.1% (25 out of 225). Factors predictive of survival on univariate analysis include the laparoscopic approach (P = 0.016), together with factors such as age, ASA status, stage of disease, tumor grade, presence of perineural invasion and vascular emboli, circumferential resection margin < 2 mm, and postoperative adjuvant chemotherapy. The survival benefit of laparoscopic surgery was no longer significant on multivariate analysis (P = 0.148). Neither 5-year overall survival (70.5% vs 61.8%, P = 0.217) nor 5-year cancer free survival (64.3% vs 66.6%, P = 0.854) were significantly different between the laparoscopic group and the converted group. CONCLUSION: LRR has equivalent long-term oncologic outcomes when compared to OP. Laparoscopic conversion does not confer a worse prognosis. PMID:27358678

    Laparoscopic surgery developed continuously over the past years becoming the gold standard for some surgical interventions. Laparoscopic colorectal surgery is well established as a safe and feasible procedure to treat benign and malignant pathologies. In this paper we studied in deep the role of laparoscopic right colectomy analysing the indications to this surgical procedure and the factors related to the conversion from laparoscopy to open surgery. We described the different surgical techniques of laparoscopic right colectomy comparing extra to intracorporeal anastomosis and we pointed out the different ways to access to the abdomen (multiport VS single incision). The indications for laparoscopic right colectomy are benign (inflammatory bowel disease and rare right colonic diverticulitis) and malignant diseases (right colon cancer and appendiceal neuroendocrine neoplasm): we described the good outcomes of laparoscopic right colectomy in all these illnesses. Laparoscopic conversion rates in right colectomy are reported as 12-16%; we described the different type of risk factors related to open conversion: patient-related, disease-related and surgeon-related factors, procedural factors and intraoperative complications. We conclude that laparoscopic right colectomy is considered superior to open surgery in the shortterm outcomes without difference in long-term outcomes.

    Background: Video-laparoscopic surgery has long been practiced in western countries; however documented practice of this minimal access surgical technique are recently emanating from Nigeria. To the best of our knowledge, this is the first documented study on laparoscopic surgery from the Niger Delta region. Aim: To evaluate the feasibility of laparoscopy as a useful tool for management of common surgical abdominal conditions in our environment. Patients and Methods: This was a prospective outcome study of all consecutive surgical patients who had laparoscopic procedures in general and pediatric surgery units of our institution from August 2011 to December 2012. Data on patient's age, gender, indication for surgery, duration of hospital stay and outcome of surgery were collected and analyzed. Results: A total of 15 laparoscopic procedures were performed during this study period with age range of 2-65 years; mean: 32.27 ± 17.86 years. There were 11 males and four females. Six laparoscopic appendicectomies, one laparoscopy-assisted orchidopexy, five diagnostic laparoscopy ± biopsy, one laparoscopic trans-abdominal pre-peritoneal herniorrhaphy for bilateral indirect inguinal hernia and two laparoscopic adhesiolysis for small bowel obstruction were performed. All were successfully completed except one conversion (6.7%) for uncontrollable bleeding in an intra-abdominal tumor. Conclusion: The practice of laparoscopic surgery in our environment is feasible and safe despite the numerous, but surmountable challenges. There is the need for adequate training of the support staff and a dedicated theatre suite. PMID:24665198

    Aims: The present study aimed to compare the surgical outcomes of patients receiving laparoscopic reversal of Hartmann’s procedure (RHP) with those receiving open surgery. Methods: Records of all patients with RHP performed in our unit (including laparoscopic and open surgery) between 2000 and 2012 were retrieved. Data were retrospectively reviewed and compared. Results: Eighty-two RHPs were performed between 2000 and 2012. Thirty-five were performed with an open approach and 47 with a laparoscopic approach. Conversion rate was 28% in the laparoscopic group. There was no difference, between the two groups, in operation time or blood loss. The median length of stay was significantly shorter in the laparoscopic group (12 vs 14 days, P = 0.002) and fewer patients in the laparoscopic group had complications with post-operative paralytic ileus (2 vs 17%, P = 0.038). None of the patients in the laparoscopic group developed incisional hernia at the conclusion of follow-up, as opposed to five in the open group (0 vs 14%, P = 0.012). Conclusion: Laparoscopic RHP is safe and feasible, with more favorable surgical outcomes, when compared with open surgery. Conversion rate is acceptable. It should be the technique of choice for patients undergoing RHP. PMID:24759821

    Osteolysis of the distal clavicle has been reported to occur from traumatic, atraumatic (overuse), or systemic causes. Three patients with bilateral osteolysis of the distal clavicles whose osteolysis did not fit these etiologic categories were evaluated. Clinical, imaging, and laboratory evaluations were nonspecific, and histologic sections of the distal clavicle showed evidence of chronic inflammation with reactive change of the articular surface. Patients either had complete resolution or marked improvement of their symptoms after bilateral distal clavicle resection at mean followup of 5 years 3 months. These cases of osteolysis of the distal clavicle represent a category of this disorder not previously described.

    OBJECTIVE: The authors compare open and laparoscopic appendectomy in a randomized fashion with regard to length of operation, complications, hospital stay, and recovery time. METHODS: Adult patients (older than 14 years of age) with the diagnosis of acute appendicitis were randomized to either open or laparoscopic appendectomy over a 9-month period. All patients received preoperative antibiotics. The operative time was calculated as beginning with the incision and ending when the wound was fully closed. Patients that were converted from laparoscopic to open appendectomy were considered a separate group. Return to normal activity and work were determined by questioning during postoperative clinic, telephone, or mailed questionnaire. RESULTS: There was a total of 169 patients randomized, 88 to the open and 81 to the laparoscopic group. The groups were similar demographically. Of the 81 laparoscopic patients, 13 (16%) were converted to open. In the open group, 70 patients (79.5%) had acute appendicitis and 21 (23.9%) had perforative appendicitis. In the laparoscopic group, 62 patients (76.5%) had acute appendicitis and 10 (12.3%) had perforative appendicitis. There was no statistical difference in the return to activity or work between the laparoscopic and open groups. The operative time was significantly longer in the laparoscopic group (102.2 minutes vs. 81.7 minutes, p < 0.01). The hospital stay of 2.2 days in the laparoscopic group and 4.3 days in the open group was statistically (p = 0.007). There was no difference in the hospital stay for those with acute appendicitis (1.89 days vs. 2.61 days, p = 0.067) compared with those with a normal appendix but with pelvic inflammatory disease (1.1 days vs. 2.3 days, p = 0.11). There was a significant difference in patients with perforative appendicitis (1.5 days vs. 9.5 days, p < 0.01). The hospital cost for patients having laparoscopic appendectomy was $6077 and for an open appendectomy $7227 (p = 0.164). There were no

    Objectives: Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery. Methods: We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman. Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months. Conclusions: Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis. PMID:28255446

    Laparoscopic herniorrhaphy is becoming an increasingly common procedure. The possible creation of intraperitoneal adhesions during laparoscopic herniorrhaphy has not been examined. For the transperitoneal hernia repair to be an acceptable option, the hypothesis that this approach will incite significant adhesions must be rejected. To test this hypothesis, 21 pigs underwent laparoscopic herniorrhaphy using a standard procedure with the implantation of a polypropylene mesh graft on one side while a sham procedure was performed on the other. These animals were later examined laparoscopically for adhesion formation and the condition of the graft. None of the 21 animals developed adhesions to the trocar sites, 12 animals developed adhesions to the area of the polypropylene mesh, and 3 developed adhesions to the side of the sham procedure. There were no adhesions involving the small intestine. It is therefore concluded that the hypothesis should be rejected and that laparoscopic herniorrhaphy does not incite significant adhesions.

When compared to open adrenalectomy, laparoscopic adrenalectomy is equally safe, effective, and curative; it is more successful in shortening hospitalization and convalescence and has less long-term morbidity. The laparoscopic approach to the adrenal is the procedure of choice for the surgical management of cortisol-producing adenomas and for patients with corticotropin (ACTH) dependent Cushing's syndrome for whom surgery failed to remove the source of ACTH. The keys to successful laparoscopic adrenalectomy are appropriate patient selection, knowledge of anatomy, delicate tissue handling, meticulous hemostasis, and experience with the technique of laparoscopic adrenalectomy.

    Traditional laparoscopic optical systems consisting of about 30 lenses have low optical magnification. To magnify tissue during surgical operations, one must change from one laparoscope to another or use a magnifying adapter between the laparoscope and the sensor. Our work focuses on how to change the sag of a liquid lens while zooming from 1 × zoom, to 2 × , and 4 × in an optical design for a laparoscope. The design includes several lenses and two liquid lenses with variable focal lengths. A pair of laparoscopes for 3-D stereoscopy is placed within a tube 11 mm in diameter. The predicted depth resolution of tissue is 0.5 mm without interpolation at 4 × zoom.

    Background Laparoscopic surgery has gained popularity over open conventional surgery as it offers benefits to both patients and health care practitioners. Although the overall risk of complications during laparoscopic surgery is recognized to be lower than during laparotomy, inadvertent serious complications still occur. Creation of the pneumoperitoneum and placement of laparoscopic ports remain a critical first step during endoscopic surgery. It is estimated that up to 50% of laparoscopic complications are entry-related, and most injury-related litigations are trocar-related. We sought to evaluate the current practice of laparoscopic entry among Canadian general surgeons. Methods We conducted a national survey to identify general surgeon preferences for laparoscopic entry. Specifically, we sought to survey surgeons using the membership database from the Canadian Association of General Surgeons (CAGS) with regards to entry methods, access instruments, port insertion sites and patient safety profiles. Laparoscopic cholecystectomy was used as a representative general surgical procedure. Results The survey was completed by 248 of 1000 (24.8%) registered members of CAGS. Respondents included both community and academic surgeons, with and without formal laparoscopic fellowship training. The demographic profile of respondents was consistent nationally. A substantial proportion of general surgeons (> 80%) prefer the open primary entry technique, use the Hasson trocar and cannula and favour the periumbilical port site, irrespective of patient weight or history of peritoneal adhesions. One-third of surgeons surveyed use Veress needle insufflation in their surgical practices. More than 50% of respondents witnessed complications related to primary laparoscopic trocar insertion. Conclusion General surgeons in Canada use the open primary entry technique, with the Hasson trocar and cannula applied periumbilically to establish a pneumoperitoneum for laparoscopic surgery. This

    Background: Anatomic reinsertion of the distal biceps is critical for restoring flexion and supination strength. Single- and double-incision surgical techniques have been reported, analyzing complications and outcomes measures. Which technique results in superior clinical outcomes and the lowest associated complications remains unclear. Hypothesis: We hypothesized that rerupture rates would be similar between the 2 techniques, while nerve complications would be higher for the single-incision technique and heterotopic ossification would be more frequent with the double-incision technique. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: A systematic review was conducted using the PubMed, MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), SPORTSDiscus, and the Cochrane Central Register of Controlled Trials databases to identify articles reporting distal biceps ruptures up to August 2013. We included English-language articles on adult patients with a minimum of 3 cases reporting single- and double-incision techniques. Frequencies of each complication as a percentage of total cases were calculated. Fisher exact tests were used to test the association between frequencies for each repair method, with P < .05 considered statistically significant. Odds ratios with 95% CIs were also computed. Results: A total of 87 articles met the inclusion criteria. Lateral antebrachial cutaneous nerve neurapraxia was the most common complication in the single-incision group, occurring in 77 of 785 cases (9.8%). Heterotopic ossification was the most common complication in the double-incision group, occurring in 36 of 498 cases (7.2%). Conclusion: The overall frequency of reported complications is higher for single-incision distal biceps repair than for double-incision repair. The frequencies of rerupture and nerve complications are both higher for single-incision repairs while the frequency of heterotopic ossification is higher for
