Surgical therapy of vulvar cancer: how to choose the correct reconstruction?

PubMed Central

2016-01-01

Objective To create a comprehensive algorithmic approach to reconstruction after vulvar cancer ablative surgery, which includes both traditional and perforator flaps, evaluating anatomical subunits and shape of the defect. Methods We retrospectively reviewed 80 cases of reconstruction after vulvar cancer ablative surgery, performed between June 2006 and January 2016, transferring 101 flaps. We registered the possibility to achieve the complete wound closure, even in presence of very complex defects, and the postoperative complications. On the basis of these experience, analyzing the choices made and considering the complications, we developed an algorithm to help with the selection of the flap in vulvoperineal reconstruction after oncologic ablative surgery for vulvar cancer. Results We employed eight types of different flaps, including 54 traditional fasciocutaneous V-Y flaps, 23 rectus abdominis myocutaneous flaps, 11 anterolateral thigh flaps, three V-Y gracilis myocutaneous flaps, three free style perforators V-Y flaps from the inner thigh, two Limberg flaps, two lotus flaps, two deep inferior epigastric artery perforator flap, and one superficial circumflex iliac artery perforator flap. The structures most frequently involved in resection were vulva, perineum, mons pubis, groins, vagina, urethra and, more rarely, rectum, bladder, and lower abdominal wall. Conclusion The algorithm we implemented can be a useful tool to help flap selection. The key points in the decision-making process are: anatomical subunits to be covered, overall shape and symmetry of the defect and some patient features such as skin laxity or previous radiotherapy. Perforator flaps, when feasible, must be considered standard in vulvoperineal reconstruction, although in some cases traditional flaps remain the best choice. PMID:27550406

The aim of this paper is to evaluate dynamic infrared thermography (DIRT) as a technique to assist in preoperative perforator selection and planning of free deep inferior epigastric perforator (DIEP) flaps. Twenty-seven patients, scheduled for secondary autologous breast reconstruction with either a free DIEP flap or superficial inferior epigastric artery flap, were included in this prospective clinical study. Preoperative mapping of perforators was performed with a hand-held Doppler and DIRT. A multidetector computer tomography scan was additionally carried out in the last 8 patients. In 23 patients a DIEP flap was used. The perforator as selected from DIRT was a suitable perforator in all DIEP flaps. The location and quality of the selected perforator from DIRT corresponded well with the multidetector computer tomography scan results. Preoperative perforator selection and planning of DIEP flaps is facilitated with the use of DIRT. The technique is noninvasive and easy to use.

Treatment of soft tissue defects caused by trauma, tumour surgery or pressure sores is a challenge to the reconstructive surgeon. Although contour and function may be restored by tissue transposition, traditional methods often cause significant donor site morbidity. This article describes how increased understanding of vascular anatomy has led to the development of new techniques. The article is based on textbooks of plastic surgery, selected articles and own clinical experience. Pedicled and free perforator flaps represent the latest development in surgical treatment of soft tissue defects. The use of perforator flaps can considerably reduce the disadvantages that are associated with other surgical methods. The use of perforator flaps demands microsurgical skills, but has many advantages. Reliable vascular supply and a good aesthetical result can be combined with minimal donor site morbidity. In many cases this technique may even give sensibility to the reconstructed area.

Background The aim of this investigation was to systematically review the current literature to provide the best data for indications, outcomes, survival, and complication rates of pedicled propeller perforator flaps for upper body defects. Methods A comprehensive literature review for articles published from January 1991 to December 2011 was performed using the PubMed, Medline, and Cochrane Databases. Articles without available full-text, single case reports or papers with excessive missing data were excluded. Papers reporting pedicle-perforator (propeller) flaps used for lower extremity reconstruction were excluded from meta-analysis. Results From the initial 1,736 studies our search yielded, 343 studies qualified for the second stage of selection. Of 117 full-text reports screened, 41 studies, met the definitive inclusion and exclusion criteria. Of the selected 41 articles, 26 were case series, original papers or retrospective reviews and were included, whereas 15 were case report papers and therefore were excluded. Two hundred ninety-five propeller flaps were reported to have been used in a total of 283 patients. Indications include repair of trauma-induced injuries, post-trauma revision surgery, cancer resection, chronic infection, pressure sores, and chronic ulcers with a major complication rate (3.3%) comparable to that of free flaps. No specific exclusion criteria for the procedure were presented in the studies reviewed. Conclusions Pedicled propeller flaps are a versatile and safe reconstructive option that are easy and quick to raise and that provide unlimited clinical solutions because of the theoretical possibility of harvesting them based on any perforator chosen among those classified in the body.

AIM: To investigate the causes and intraoperative detection of endoscopic retrograde cholangiopancreatography (ERCP)-related perforations to support immediate or early diagnosis. METHODS: Consecutive patients who underwent ERCP procedures at our hospital between January 2008 and June 2013 were retrospectively enrolled in the study (n = 2674). All procedures had been carried out using digital fluoroscopic assistance with the patient under conscious sedation. For patients showing alterations in the gastrointestinal anatomy, a short-type double balloon enteroscope had been applied. Cases of perforation had been identified by the presence of air in or leakage of contrast medium into the retroperitoneal space, or upon endoscopic detection of an abdominal cavity related to the perforated lumen. For patients with ERCP-related perforations, the data on medical history, endoscopic findings, radiologic findings, diagnostic methods, management, and clinical outcomes were used for descriptive analysis. RESULTS: Of the 2674 ERCP procedures performed during the 71-mo study period, only six (0.22%) resulted in perforations (male/female, 2/4; median age: 84 years; age range: 57-97 years). The cases included an endoscope-related duodenal perforation, two periampullary perforations related to endoscopic sphincterotomy, two periampullary perforations related to endoscopic papillary balloon dilation, and a periampullary or bile duct perforation secondary to endoscopic instrument trauma. No cases of guidewire-related perforation occurred. The video endoscope system employed in all procedures was only able to immediately detect the endoscope-related perforation; the other five perforation cases were all detected by subsequent digital fluoroscope applied intraoperatively (at a median post-ERCP intervention time of 15 min). Three out of the six total perforation cases, including the single case of endoscope-related duodenal injury, were surgically treated; the remaining three cases were treated with conservative management, including trans-arterial embolization to control the bleeding in one of the cases. All patients recovered without further incident. CONCLUSION: ERCP-related perforations may be difficult to diagnose by video endoscope and digital fluoroscope detection of retroperitoneal free air or contrast medium leakage can facilitate diagnosis.

Perforated gastric cancer is relatively rare and the incidence is reported about 1% of all the cases of gastric cancer. We retrospectively analyzed the clinical data of the consecutive 12 patients with perforated gastric cancer who underwent operation in our hospital between January 2005 and December 2016. There were 5 men and 7 women, with an average age of 65.8 years old(34-87). Perforated gastric cancer occurred in the region U(1 cases), M(6 cases), L(5 cases). There were 11 cases with distant metastasis. We could successfully diagnosed as perforated gastric cancer in 8 cases before emergency operation. Gastrectomy was performed in 5 cases. However, the curative resection was performed only 1 case. Prognosis of perforated gastric cancer is poor. We considered as an appropriate two-step surgical strategy that the first step of surgery is an acute peritonitis treatment followed by radical gastrectomy with lymphadenectomy.

Stercoral perforation of the colon is rare but carries with it significant morbidity and mortality. Stercoral perforation usually occurs in elderly, immobile patients with chronic constipation. In this manuscript, we report the case of stercoral perforation in a patient due to chronic heroin dependence. We report the case of a 56-year-old male patient with stercoral perforation, diagnosed by computed tomography, secondary to heroin dependence, requiring proctocolectomy and an end ileostomy. There are very few reports in the literature describing cases of stercoral perforation and questions have been asked about the importance of preoperative cross-sectional imaging. In our case, the diagnosis of stercoral perforation was made only on CT. Although this is not the first such case to be reported, it is significant as preoperative CT imaging was influential not only in determining the aetiology of the abdominal distension seen on the plain film, but also in detecting the pneumoperitoneum which was not evident clinically or on plain radiographs.

Laparoscopy has gained clinical acceptance in many subspecialties in the last decade. The conventional open surgery for peritonitis carries significant morbidity and mortality. The present study was done to extend and evaluate benefits of minimally invasive surgery in this subset of patients. This was a prospective study spanning over a period of four years. All those patients diagnosed as having peritonitis on clinical assessment and preoperative investigations and those who were stable enough haemodynamically were included in this study. After initial resuscitation for few hours, they underwent diagnostic and therapeutic laparoscopy to identify the cause of peritonitis and to confirm the pathology. All cases were done under general anesthesia, using three standard ports at appropriate sites according to pathology. Patients were treated by different procedures either laparoscopically or with laparoscopic assistance after diagnosis. Operative and post operative data was collected and analyzed. Ninety two cases of peritonitis underwent diagnostic and therapeutic laparoscopy. Mean age of patient was 46.5 years. 24 patients were diagnosed as perforated duodenal, in 14 (58.3%) patients laparoscopic suture repair was done and in 8 (33.3%) small upper midline incision was given and perforation was repaired. Out of 32 patients having perforated appendix, 25 (78.1%) patients laparoscopic appendectomy was done while in 7 (21.8%) perforation was dealt by laparoscopic assistance. Out of 14 patients of ileal perforation 6 (42.8%) with minimal contamination laparoscopic suture was applied, while in 8 (57.1%), perforated loop was brought out by making small window and perforation was closed. All 22 patients with pelvic sepsis needed only aspiration of pus and peritoneal lavage. Only one patient died post operatively and 2 (2.1%) patients developed fistula. 6 (6.5%) patients developed port site infection. Laparoscopic management is feasible, safe and effective surgical option for patients with peritonitis due to different abdominal emergencies in properly selected cases with higher diagnostic yield and a faster postoperative recovery.

feasibility and advantages of laparoscopic approach in performed duodenal ulcer have no longer to be demonstrated. Laparoscopic suture and peritoneal cleaning expose to a conversion rate between 10 and 23%. However less than laparotomy, morbidity of this approach is not absent. This study aim to analyze factors exposing to conversion after laparoscopic approach of perforred duodenal ulcer. We also aim to define the morbidity of this approach and predictive factors of this morbidity Methods: Retrospective descriptive study was conducted referring all cases of perforated duodenal ulcer treated laparoscopically over a period of ten years, running from January 2000 to December 2010. All patients were operated by laparoscopy with or without conversion. We have noted conversion factors. A statistical analysis with logistic regression was performed whenever we have sought to identify independent risk factors for conversion verified as statistically significant in univariante. The significance level was set at 5%. Analytic univariant and multivariant study was performed to analyze morbidity factors. 290 patients were included. The median age was 34ans.T he intervention was conducted completely laparoscopically in 91.4% of cases. The conversion rate was 8.6%. It was selected as a risk factor for conversion: age> 32 years, a known ulcer, progressive pain, renal function failure, a difficult peritoneal lavage and having a chronic ulcer. Postoperative morbidity was 5.1%. Three independent risk factors of surgical complications were selected: renal failure, age> 45 years, and a chronic ulcer appearance. Laparoscopic treatment of perforred duodenal ulcer expose to a conversion risk. Morbidity is certainly less than laparotomy and a better Knowledge of predictif's morbidity factors become necessary for a better management of this disease.

We have previously reported a small series on the closure of large myelomeningocele (MMC) defects with a keystone design perforator island flap (KDPIF) in a paediatric neurosurgical centre in Australia. We are now presenting an updated longer term follow-up of an expanded series demonstrating longer term durability of this vascularized flap for large myelomeningocele defects. The prospective data from the Monash Neurosurgical Database were used to select all cases of MMC between December 2008 and September 2016. Retrospective analysis of the neurosurgical database revealed an additional three patients who underwent KDPIF closure at the Monash Medical Centre for MMC repair at birth. Wound healing was satisfactory in all six cases. With delayed follow-up, there was no associated skin flap separation, skin flap dehiscence, skin flap necrosis, cerebro-spinal fluid leak, however two infections were encountered, both resolved with conservative management including antibiotics and simple washout. In this expanded case series with increased longevity of follow-up, the keystone design perforator island flap remains a robust alternative for closure of large myelomeningocele defects.

Vertical Profunda Artery Perforator Flap for Plantar Foot Wound Closure: A New Application.

2018-02-01

Plantar foot reconstruction requires special consideration of both form and function. There are several fasciocutaneous flap options, each with indications and reservations. This case presents a new application of the vertical profunda artery perforator flap for definitive closure of a neuropathic foot ulcer in a young woman with spina bifida. The postoperative course was uneventful, and the flap survived completely. The surgical and donor sites were without wound recurrence at 5-month follow-up. Understanding the variability of foot flap options is important because of unique cases such as the one presented where the wound was caused by specific and less commonly observed foot anatomy. The specific choice to use the vertical profunda artery perforator flap for this patient and her neuropathic wound type was made based on its excellent flexibility, durability, and donor site appeal. The vertical profunda artery perforator flap has adequate surface area and bulk and a favorable pedicle length and caliber, can be thinned, and leaves a donor scar in a less conspicuous area than other popular free flaps for lower-extremity reconstruction. For these reasons, it should be considered a first-line therapy for free flap coverage of selected foot wounds.

Little is known on the pattern of perforated peptic ulcer in Ethiopia. To evaluate the early, outcome of management, a five-year retrospective analysis of 74 operated cases of perforated peptic ulcer was undertaken. Perforated peptic ulcer accounted for 3.4% of the adult emergency surgical procedures. The mean age was 32.6 years, with a male to female ratio of 7.2 to 1.0. Fifty-six percent of the cases were unmarried. In nearly 22.0% of the patients, no previous history of peptic ulcer disease was documented. Delay in diagnosis was noted in 95% of the cases. Most patients had duodenal ulcer perforation, and about 78% had purulent peritonitis at laparotomy. Fourteen died in hospital. Early presentation of patients to surgical care facilities may reduce morbidity and mortality in cases of peptic ulcer perforation.

Delayed lead perforation (occurring more than 1 month after implantation) is a rare complication. Its pathophysiology and optimal management are currently unclear. Three cases of delayed lead perforation (6-10 month) were identified in patients with low-profile active fixation leads. All cases presented in a subacute fashion with pleuritic chest pain with confirmatory chest x-ray and device interrogation. Given the potential complications of a perforated lead, all cases had the lead extracted under TEE observation with cardiac surgery backup in the operating room. All patients tolerated extraction without complication. Based on these cases, we recommend a management scheme for patients who present with delayed lead perforation.

Twenty-nine laparotomies for gynaecological cancers over 3 months. Gloves used during laparotomies for gynaecological cancer were tested for perforations by the air inflation and water immersion technique. Parameters recorded were: type of procedure, localisation of perforation, type of gloves, seniority of surgeon, operation time and awareness of perforations. Glove perforation rate. Perforations were found in gloves from 27/29 (93%) laparotomies. The perforation rate was 61/462 (13%) per glove. The perforation rate was three times higher when the duration of surgery was more than 5 hours. The perforation rate was 63% for primary surgeons, 54.5% for first assistant, 4.7% for second assistant and 40.5% for scrub nurses. Clinical fellows were at highest risk of injury (94%). Two-thirds of perforations were on the index finger or thumb. The glove on the nondominant hand had perforations in 54% of cases. In 50% of cases, the participants were not aware of the perforations. There were less inner glove perforations in double gloves compared with single gloves (5/139 versus 26/154; P = 0.0004, OR = 5.4, 95% CI 1.9-16.7). The indicator glove system failed to identify holes in 44% of cases. Glove perforations were found in most (93%) laparotomies for gynaecological malignancies. They are most common among clinical fellows, are often unnoticed and often not detected by the indicator glove system.

Despite confirmation of a reliable perforasome in the dorsal scapular artery in an anatomic study, a true perforator flap has not been recommended in previous clinical studies because of concerns regarding insufficient perfusion in the distal region. In this report, we present two cases of reconstruction for occipital defects caused by tumor extirpation using pedicled dorsal scapular artery perforator flaps without a muscle component. To secure the perfusion of the dorsal scapular artery perforator flap, inclusion of an additional perforator was attempted for perfusion augmentation. The second dorsal scapular artery perforator was harvested in one case. In an additional case, the sixth dorsal intercostal artery perforator with a branch that directly connected with the dorsal scapular artery within the trapezius muscle was additionally harvested. The flaps survived without any perfusion-related complications, including tip necrosis, and no donor site morbidities were observed. We suggest that a perfusion augmented dorsal scapular artery perforator flap by harvesting multiple perforators could be a safe and useful alternative for reconstructive surgery of head and neck defects. © 2014 Wiley Periodicals, Inc.

Perforation of the bladder related to long-term indwelling urethral catheter is a rare and serious complication. A 85-year-old man with an indwelling urethral catheter presented severe hematuria, abdominal pain with rebound tenderness and muscular tension over the suprapubic area after the exchange of the urethral catheter. Computed tomography and cystogram revealed experitoneal bladder perforation due to indwelling catheter. Three weeks after the indwelling urethral catheter had been placed, the perforation was closed. In most cases, laparotomy and suprapubic cystostomy are performed. We describe the case of experitoneal bladder perforation successfully treated by urethral drainage.

Autologous breast reconstructive surgery with deep inferior epigastric artery (DIEA) perforator flaps has become the mainstay for breast reconstructive surgery. CT angiography and three-dimensional image post processing can depict the number, size, course and location of the DIEA perforating arteries for the pre-operative selection of the best artery to use for the tissue flap. Knowledge of the location and selection of the optimal perforating artery shortens operative times and decreases patient morbidity.

Nasal septum perforation (NSP) is a communication between the two nasal cavities. This review contributes to the better knowledge of NSP causes, diagnosis, and treatment. NSP prevalence is about 1%. Clinical presentation may range from absence of symptoms to the presence of bothersome sinonasal symptoms. NSP is more frequently caused by trauma or post-surgery, inflammatory diseases, and abuse substances. Conservative management (nasal irrigation, topical use of antibiotic or lubricant ointments, or placement of prosthesis) is considered the first-line treatment. Symptomatic NSP not improving with local therapies usually requires surgical approach. Selection of the technique for the endoscopic septal repair depends on perforation characteristics and surgeon experience. When NSP is diagnosed, its cause has to be promptly determined. Most of them can be controlled with conservative measures. Surgical/endoscopic approaches are usually needed in refractory cases, and new repair techniques have to be considered.

Investigation on the accuracy and reliability of in-situ stress measurements using hydraulic fracturing in perforated cased holes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Warpinski, N.R.

At present, the only viable technique for accurately measuring stresses at depth in a borehole is hydraulic fracturing. These have been termed microfracs because very small amounts of fluid are injected at low flow rates into the formation. When the well is shut in, the pressure immediately drops from the injection pressure to the instantaneous shut-in pressure (ISIP) which is approximately equal to sigma/sub min/. In general, the ISIP can be measured quite accurately in open holes. For most oil and gas applications, however, it is impossible or impractical to conduct these tests in an open-hole environment. The effects ofmore » the casing, cement annulus, explosive perforation damage, and random performation orientation are impossible to predict theoretically, and laboratory tests are usually conducted under nonrealistic conditions. A set of in situ experiments was conducted to evaluate the accuracy and reliability of this technique, to aid in the selection of an optimum perforation schedule, and to develop a diagnostic capability from the pressure response.« less

Stercoral perforation of the colon proximal to an end colostomy.

Stercoral perforation of the colon is rare, and has not previously been reported as a postoperative complication, proximal to an end colostomy. Two such cases are reported; in addition in one the stercoral perforation was recurrent, emphasizing the multifocal nature of the disease. Both cases demonstrate the failure of standard techniques to deal with scybala in the loaded proximal colon. It is, therefore, suggested that intra-operative orthograde colonic lavage is indicated to protect a terminal colostomy from the risk of stercoral perforation in such cases. PMID:2062783

Acute abdomen during pregnancy is a medico-surgical emergency demanding concerted, synchronized specialties approach of obstetrician, surgeon and gastroenterologist. Duodenal perforation is one of the rarer causes of acute abdomen in pregnancy. Here, we report a case of duodenal perforation with peritonitis in third trimester of pregnancy requiring surgical management. Our aim of reporting this case is to stress the physicians to keep the differential of duodenal perforation also in mind while dealing with cases of acute abdomen in pregnancy and to proceed with multidisciplinary approach for better feto-maternal outcome.

Uterine perforation by intrauterine devices (IUDs) is a rare but well recognized complication. In the past, the presence of adhesions and perforation of viscera often resulted in the need for a laparotomy to remove the IUD. However, advances in laparoscopic technique have allowed surgeons to safely retrieve perforated IUDs. In this review, we analyze uterine perforation by an IUD and assess laparoscopic vs. open methods for removal of a perforated IUD. A systematic search strategy was applied to several electronic bibliographic databases: Medline/Pubmed, Embase, Cochrane Library, and OCLC PapersFirst. Key words used were IUD, laparoscopy, and uterine perforation. One hundred seventy-nine cases of attempted laparoscopic removal of perforated IUDs were identified in the English literature between 1970 and 2009. Patient age ranged from 17 to 49 years. Diagnostic laparoscopy was performed in all 179 cases reported. Laparoscopic removal of perforated IUDs was achieved successfully in 64.2% (115/179) of cases. This systematic review highlights how advances in laparoscopic technique and skill have allowed surgeons to safely retrieve IUDs without laparotomy. We recommend an attempt at laparoscopic removal as first-line treatment in symptomatic patients and as a reasonable treatment option in asymptomatic patients. Copyright © 2012 Elsevier Inc.

We describe the clinical presentation, evaluation, management and outcome of patients experiencing small bowel perforation following radiation therapy for cervical cancer. A database consisting of 95 Japanese women with stage 0-4 A cervix cancer treated between 1991 and 2004 contained seven patients (7.4%) with small bowel perforation. The median age at the time of perforation was 72.5 years (range 62-78). The median time from completion of radiotherapy to perforation was 6 months (range 2-58). Surgery (one small bowel resection and anastomosis with diversion; six small bowel resection and anastomosis) was performed immediately in all seven patients. One of seven patients died of small bowel perforation (i.e. mortality rate was 14%). Bowel adhesion was detected during the operation in only three cases (43%). Signs of peritonitis were absent in six cases (86%). Severe abdominal pain was seen in all seven patients. The perforation site was ileum in all seven cases. In all patients, pathological changes were compatible with postirradiation injury of the gastrointestinal tract. The presenting complaints of patients with bowel perforation following radiotherapy vary, and signs of peritonitis may be absent. Emergency physicians must be alert for these complications in patients who have been treated with radiotherapy.

A few cases of acute abdomen caused by perforation of small-intestinal gastrointestinal stromal tumours (GISTs) have been reported in the literature. Together with a review of the published cases, here we report a case of an elderly patient with peritonitis due to spontaneous perforation of a GIST of the jejunum. An 82-year-old man was admitted to the emergency unit of our hospital with fever and severe abdominal pain. An abdominal enhanced computed tomography scan detected a 6cm solid mass in the left upper quadrant adherent to a jejunal loop and surrounded by free fluid and free air. Due to the radiological features of the mass, the diagnosis of a perforation of a GIST arising from the jejunum wall was suspected. The patient underwent emergency laparotomy. Intraoperative findings confirmed diffuse peritonitis secondary to jejunal tumour perforation. A segmental resection of the jejunum containing the mass was performed followed by a mechanical end-to-side anastomosis. The histopathologic examination of the mass confirmed the diagnosis of a perforated GIST of the small intestine (high-risk category). The post-operative course was uneventful and the patient was treated with adjuvant imatinib therapy. Twenty-one other cases of spontaneous perforation of small intestine GISTs are reported in the literature and are summarized in the present review. The described case is the tip of the iceberg and spontaneous rupture or perforation of GISTs are a far more frequent first presentation of this rare tumour. Copyright © 2014 The Authors.

Fungi are unusually rare causes of gastric perforation, with most cases of gastric perforation occurring as complications of peptic ulcer disease (PUD), nonsteroidal anti-inflammatory drugs (NSAIDs) and gastric neoplasms. Here, we report the case of a 70-year-old Nigerian male who presented with severe epigastric pain, with no associated history of PUD, NSAIDs use or gastric neoplasm. An emergency exploratory laparotomy was performed and a gastric perforation was discovered and repaired. Histopathological examination of the gastric perforation edge biopsy revealed an intense Candida growth consisting of numerous fungal spores and hyphae invading and destroying the gastric wall. He was subsequently treated with fluconazole antifungal and discharged home after an uneventful postoperative period. PMID:26229723

The repair of extensive upper limb skin lesions in pediatric patients is extremely challenging due to substantial limitations of flap size and donor-site morbidity. We aimed to create an oversize preexpanded flap based on intercostal artery perforators for large-scale resurfacing of the upper extremity in children. Between March 2013 and August 2016, 11 patients underwent reconstructive treatment for extensive skin lesions in the upper extremity using a preexpanded intercostal artery perforator flap. Preoperatively, 2 to 4 candidate perforators were selected as potential pedicle vessels based on duplex ultrasound examination. After tissue expander implantation in the thoracodorsal area, regular saline injections were performed until the expanded flap was sufficient in size. Then, a pedicled flap was formed to resurface the skin lesion of the upper limb. The pedicles were transected 3 weeks after flap transfer. Flap survival, complications, and long-term outcome were evaluated. The average time of tissue expansion was 133 days with a mean final volume of 1713 mL. The thoracoabdominal flaps were based on 2 to 6 pedicles and used to resurface a mean skin defect area of 238 cm ranging from 180 to 357 cm. In all cases, primary donor-site closure was achieved. Marginal necrosis was seen in 5 cases. The reconstructed limbs showed satisfactory outcome in both aesthetic and functional aspects. The preexpanded intercostal artery perforator flap enables 1-block repair of extensive upper limb skin lesions. Due to limited donor-site morbidity and a pedicled technique, this resurfacing approach represents a useful tool especially in pediatric patients.

Colorectal perforation by self-induced hydrostatic pressure: a report of two cases.

PubMed

2013-02-01

Most iatrogenic colorectal perforations occur as a result of endoscopic or fluoroscopic studies. Accidents associated with hydrostatic pressure-induced perforation are rarely reported, and self-induced hydrostatic pressure is an extremely rare cause of perforation because the anal sphincter complex may provide a protective barrier against perianal hydrostatic pressure. We present two cases of rectosigmoid colon perforation secondary to self-induced hydrostatic pressure. A 61-year-old man and a 45-year-old man presented with abdominal pain after forceful entry of tap water into the rectum, during rinsing of the anus after defecation in the first case, and during self-administered enema in the second case. Emergency operations were performed with the suspicion of hydrostatic pressure-induced rectal injury, and showed rectosigmoid mesenteric perforation in both cases. Resection of the diseased segment and end colostomy (Hartmann's procedure) was performed in the first case, and primary resection and anastomosis in the second case. The pathologic results showed abrupt loss of the colonic wall in the mesenteric border, without evidence of other inflammatory disease; these findings were consistent with acute mechanical colon injury. The postoperative course in both cases was uneventful. These cases put forth an unusual type of colorectal injury, caused specifically by hydrostatic pressure, thus adding to the available literature on hydrostatic pressure-induced injury.

We report a case of esophageal perforation (Boerhaave syndrome) caused by vomiting related to a duodenal ulcer with pyloric stenosis. A 45-year-old male presented with left chest pain and dyspnea after forceful vomiting. Chest radiography and computed tomography (CT) revealed a massive left pleural effusion and left tension pneumothorax. Abdominal CT revealed pyloric stenosis with a remarkably dilated stomach. Tube thoracostomy and nasogastric suction were immediately performed and we selected conservative treatment based on the following factors-a stable general condition without sepsis, early diagnosis, and good drainage. Esophagogastroduodenoscopy on hospital day 9 demonstrated a healing ulcer in the lower esophagus and pyloric stenosis. We performed distal gastrectomy as elective surgery for pyloric stenosis due to a duodenal ulcer on hospital day 30. In summary, an esophageal perforation with contamination spreading to the thoracic cavity was successfully treated with conservative treatment.

Esophageal perforation is a condition associated with high morbidity and mortality rates; it requires early diagnosis and treatment. The most common complication of esophageal rupture is mediastinitis. There are several case reports in the literature of mediastinitis secondary to esophageal perforation and development of aortic pseudoaneurysm as a complication. We report the case of a patient with an 8-day history of esophageal perforation due to foreign body (fishbone) with mediastinitis and aortic pseudoaneurysm. The diagnosis was made using Computed Tomography (CT) with intravenous and oral water-soluble contrast material. An esophagogastroduodenoscopy did not detect the perforation. PMID:26977330

Objective To examine the association between selective serotonin reuptake inhibitors and risk of upper gastrointestinal bleeding. Design Population based case-control study. Setting General practices included in the UK general practice research database. Subjects 1651 incident cases of upper gastrointestinal bleeding and 248 cases of ulcer perforation among patients aged 40 to 79 years between April 1993 and September 1997, and 10 000 controls matched for age, sex, and year that the case was identified. Interventions Review of computer profiles for all potential cases, and an internal validation study to confirm the accuracy of the diagnosis on the basis of the computerised information. Main outcome measures Current use of selective serotonin reuptake inhibitors or other antidepressants within 30 days before the index date. Results Current exposure to selective serotonin reuptake inhibitors was identified in 3.1% (52 of 1651) of patients with upper gastrointestinal bleeding but only 1.0% (95 of 10 000) of controls, giving an adjusted rate ratio of 3.0 (95% confidence interval 2.1 to 4.4). This effect measure was not modified by sex, age, dose, or treatment duration. A crude incidence of 1 case per 8000 prescriptions was estimated. A small association was found with non-selective serotonin reuptake inhibitors (relative risk 1.4, 1.1 to 1.9) but not with antidepressants lacking this inhibitory effect. None of the groups of antidepressants was associated with ulcer perforation. The concurrent use of selective serotonin reuptake inhibitors with non-steroidal anti-inflammatory drugs increased the risk of upper gastrointestinal bleeding beyond the sum of their independent effects (15.6, 6.6 to 36.6). A smaller interaction was also found between selective serotonin reuptake inhibitors and low dose aspirin (7.2, 3.1 to 17.1). Conclusions Selective serotonin reuptake inhibitors increase the risk of upper gastrointestinal bleeding. The absolute effect is, however, moderate and about equivalent to low dose ibuprofen. The concurrent use of non-steroidal anti-inflammatory drugs or aspirin with selective serotonin reuptake inhibitors greatly increases the risk of upper gastrointestinal bleeding. PMID:10531103

A case of crestal root perforation and periapical lesion in a maxillary left lateral incisor is reported. Teeth with root perforation present technical difficulties in their clinical management because of their complex defects. In the present case, surgical endodontic treatment was chosen. The apical and lateral pathology was curetted, the tooth root was resected, and a retrograde root restoration of amalgam was placed in a root-end cavity and perforation site. A 10-year follow-up clinical and radiographic examination showed an asymptomatic tooth with osseous healing proceeding.

Duodenal perforation is a complication of endoscopic mucosal resection. Liver abscess secondary to iatrogenic perforation is extremely rare. A 43-year-old female visited the hospital to remove a sub-epithelial tumor on the duodenal bulb. After endoscopic mucosal resection with band ligation, duodenal perforation occurred. Endoscopic closure was performed successfully using a clipping device to manage duodenal perforation. After 4 weeks, the patient visited our outpatient clinic due to abdominal pain and fever. Abdominal computed tomography showed liver abscess that involved segment three. Liver abscess was resolved with a 10-week antibiotic treatment. To the best of our knowledge, no case of liver abscess secondary to duodenal perforation by endoscopic resection was reported to date in Korea. Here, we report a case of liver abscess caused by a duodenal perforation after endoscopic mucosal resection.

Sunitinib, a multitargeted tyrosine kinase inhibitor, is widely used in the treatment of carcinoma. Adverse events associated with this treatment, including fatigue, diarrhea, and hematotoxicity, have been reported in clinical trials. Bowel perforation is a surgical emergency that requires immediate treatment depending on the location and progression of the tumor. We report 2 cases of bowel perforation during sunitinib treatment. The patients presented with diffuse peritonitis, and emergency exploratory laparotomy was performed. We speculate that the underlying mechanisms were decrease in capillary density of the normal mucosa in case 1 and tumor shrinkage because of sunitinib treatment in case 2. To the best of our knowledge, this is the first study to report the pathological findings implicating bowel perforation due to sunitinib treatment. Further investigations are needed to clarify the risk factors for intestinal perforations associated with sunitinib treatment.

Evaluation of dynamic infrared thermography as an alternative to CT angiography for perforator mapping in breast reconstruction: a clinical study.

PubMed

The current gold standard for preoperative perforator mapping in breast reconstruction with a DIEP flap is CT angiography (CTA). Dynamic infrared thermography (DIRT) is an imaging method that does not require ionizing radiation or contrast injection. We evaluated if DIRT could be an alternative to CTA in perforator mapping. Twenty-five patients scheduled for secondary breast reconstruction with a DIEP flap were included. Preoperatively, the lower abdomen was examined with hand-held Doppler, DIRT and CTA. Arterial Doppler sound locations were marked on the skin. DIRT examination involved rewarming of the abdominal skin after a mild cold challenge. The locations of hot spots on DIRT were compared with the arterial Doppler sound locations. The rate and pattern of rewarming of the hot spots were analyzed. Multiplanar CT reconstructions were used to see if hot spots were related to perforators on CTA. All flaps were based on the perforator selected with DIRT and the surgical outcome was analyzed. First appearing hot spots were always associated with arterial Doppler sounds and clearly visible perforators on CTA. The hot spots on DIRT images were always slightly laterally located in relation to the exit points of the associated perforators through the rectus abdominis fascia on CTA. Some periumbilical perforators were not associated with hot spots and showed communication with the superficial inferior epigastric vein on CTA. The selected perforators adequately perfused all flaps. This study confirms that perforators selected with DIRT have arterial Doppler sound, are clearly visible on CTA and provide adequate perfusion for DIEP breast reconstruction.

Perforated Meckel's diverticulitis complicating active Crohn's ileitis: a case report

PubMed Central

2009-01-01

Introduction In Crohn's disease, the extension of active terminal ileitis into a Meckel's diverticulum is possible, but usually has no impact on clinical decision-making. We describe an original surgical approach in a young woman presenting with a combination of perforated Meckel's diverticulitis and active Crohn's ileitis. Case presentation We report the case of a 22-year-old woman with Crohn's disease, who was admitted for abdominal pain, fever and diarrhoea. CT scan demonstrated active inflammation of the terminal ileum, as well as a fluid collection in the right iliac fossa, suggesting intestinal perforation. Laparoscopy was performed and revealed, in addition to extensive ileitis, a 3 × 3 cm abscess in connection with perforated Meckel's diverticulitis. It was therefore possible to avoid ileocaecal resection by only performing Meckel's diverticulectomy; pathological examination of the surgical specimen revealed the presence of transmural inflammation with granulomas and perforation of the diverticulum at its extremity. Conclusion Crohn's disease of the ileum may be responsible for Meckel's diverticulitis and cause perforation which, in this case, proved to be a blessing in disguise and spared the patient an extensive small bowel resection.

Several studies have advocated laparoscopic simple closure (LSC) as the treatment of choice for perforated peptic ulcer disease (PUD). However, there has been no comprehensive community-based evaluation of the advantages of using LSC over open simple closure (OSC). Using an administrative database, we evaluated LSC versus OSC for patients with perforated ulcers. From 6,334 patients with perforated ulcers, we identified 2,909 simple closure cases between 2006 and 2010. Study variables were demographics, mortality, co-morbidities, complications, ulcer location, surgical timing, blood transfusion, postoperative ventilation, operating room (OR) time, time to resumption of oral food intake, length of stay (LOS), and total charges. After matching patient baseline variables between OSC and LSC, we performed multivariate analyses to assess the impacts of LSC on mortality, complications, and ventilation administration. A total of 2,073 OSC cases and 836 LSC cases were identified in 670 hospitals. Younger age, duodenal ulcer, and pre-existing PUD were indicators for selection of LSC. Matching analysis indicated a correlation between LSC and lower mortality, less frequent postoperative and overall blood transfusion, shorter LOS, earlier return to oral intake, and longer OR time. There was no difference between OSC and LSC in complication rate or mortality. Longer OR time was correlated with a higher complication rate and the need for ventilation, the latter of which was independently associated with an increase in mortality. Because longer OR time was associated with more frequent complications and ventilation, surgeons should obtain the skills and strategies necessary to accomplish LSC without extending OR time improperly.

Iatrogenic perforation of perivaterian duodenal diverticulum: report of a case

The author reports a case of iatrogenic perforation of a duodenal diverticulum, an extremely rare occurrence, during percutaneous radiologic extraction of a retained common-bile-duct stone. Perforation was related to the perivaterian location of the duodenal diverticulum. Because an inflammatory reaction was present, tube duodenostomy was chosen over excision, closure and drainage to prevent the complication of lateral duodenal fistula and sepsis. Whenever iatrogenic duodenal perforation is suspected, prompt radiologic documentation and early surgical consultation should be sought. PMID:8697327

Extra-abdominal abscesses of gastrointestinal origin developing within the lumbar subcutaneous tissues are extremely rare. We report two cases of retroperitoneal bowel perforation presenting spontaneously at admission with a lumbar abscess trespassing the lumbar triangle of Petit, a classical "locus of minus resistencia" of the posterior abdominal wall. The first case was caused by perforation of a retrocecal appendicitis--being concomitantly responsible of a necrotizing fasciitis of the thigh--and in the second case perforation was caused by left colonic diverticulitis. In both cases, the full diagnosis was made with abdominal CT. The patients were threatened by a two-step surgical approach comprising a direct posterior percutaneous drainage of the abscess followed by classical laparotomy.

Gallbladder perforation (GBP) is rare and as a complication of typhoid fever is extremely rare. We present two consecutive patients with GBP diagnosed incidentally at laparotomy. Information on the management of two patients with gallbladder perforation seen at Federal Medical Centre Azare in June and October 2008 was extracted from their case records. The two patients were both males aged 13 years and 16 years. They both presented with high fever of more than 2 weeks duration; and abdominal pain and distension. Both patients had features of generalised peritonitis. Pre-operative diagnoses of typhoid enteric perforation were made based on a positive Widal test. Intra-operative findings however, were that of bile peritonitis and gallbladder perforation. Both had cholecystectomy. Culture of the bile aspirate yielded Salmonella typhi. Gallbladder perforation secondary to typhoid fever should be considered as a differential diagnosis in patients with suspected typhoid enteric perforation in typhoid fever endemic region.

Precise patient selection criteria are necessary to guide the surgeon in selecting laparoscopic repair for patients with perforated peptic ulcers. The aims of this study are to report surgical outcomes after surgery for perforated duodenal ulcers and identify risk factors for predicting failure of laparoscopic simple closure for perforated duodenal ulcer. In total, 77 patients who underwent laparoscopic simple closure for perforated duodenal ulcers from January 2007 to September 2013 were retrospectively analyzed. Patients were divided into totally laparoscopic and conversion groups. The characteristics of patients, intraoperative findings, postoperative complications, conversion rates and suture leakage rates of each group were investigated. Laparoscopic repair was completed in 69 (89.6%) of 77 patients, while 8 (10.4%) underwent conversion to open repair. Patients in the conversion group had longer perforation time, larger perforation size, more suture leakage, longer hospital stay, and higher 30-day mortality rate than those in the totally laparoscopic group. The size of perforation was the only risk factor for conversion in multivariable analysis. Patients with an ulcer perforation size of ≥9 mm or with perforation duration of ≥12.5 h had a significantly increased risk for conversion and suture leakage. Ulcer size of ≥9 mm is a significant risk factor for predicting conversion in laparoscopic simple closure. Suture leakage is associated with ulcer size (9 mm) and duration of perforation (12.5 h).

To explore and analyze the current status in management of patients with perforated peptic ulcers (PPU). A retrospective study carried out at the Surgical Department, Al-Gamhouria Teaching Hospital, Aden, Yemen. Patients admitted with perforated benign peptic ulcers from January 1997 to December 2006 were included in the study. A total of 156 patients, 138 (88.5%) male and 18 (11.5%) female, with an overall mean age of 39.08 years (range 14-75 years) and a higher frequency of PPU was noted in patients 21-40 years (58.3%). The perforated duodenal ulcer and perforated gastric ulcer ratio was 4.38:1. The mean time of presentation was 16.5 hours, and operative intervention after admission was 5.25 hours. Simple perforation closure was used in 91.7% of the patients. Postoperative complication rate was 41% (statistically significant in cases admitted later than 12 hours), wound sepsis making the majority at 55.2%, 6 deaths (3.9%), the correlation with presentation time was not significant. The overall mean post-operative hospitalization period was 12.76 days; 14.7% of the patients stayed more than 3 weeks. Younger patients (21-40 years) were frequently affected. Emphasis should be placed on shortening the time to surgery. Simple closure remains the selected treatment in the majority of patients. Overall post-operative mortality was low (3.9%). Improving the surgical skills, wound care, administrative regulations, hospital environment, and equipment are needed to reduce the high rate of complications.

Left ventricular (LV) perforation is one of the rare and most serious complications of transcatheter aortic valve implantation (TAVI). The study aim was to determine the pathophysiological factors associated with this serious complication. A retrospective study was conducted of pathophysiological factors shown in echocardiograms and computed tomography angiograms performed preoperatively in patients who developed LV perforation during transfemoral TAVI (study group) with regards to anatomic and functional variables. Results were then compared with data acquired from a randomly selected sample of patients without perforation (control group). Among 963 TAVI cases, LV perforation occurred in 11 patients (three males, eight females; mean age 79 years). These patients showed complications of LV perforation that required emergency sternotomy and repair of injury to the left ventricle. Ten patients were rescued by the procedure, but one patient died during surgery. Focus on preoperative factors and intraoperative steps was established in favor to identify possible predictors of LV perforation. A LV cavity size <4.2 cm and a hypercontractile ventricle were identified in 10 patients (90%). Only one patient had a dilated cardiomyopathic left ventricle, with a cavity size of 6.1 cm and an ejection fraction of 10%. The present study results revealed other specific patient-related factors, namely a narrow aorto-mitral angle and a thin ventricular muscular wall despite long-standing aortic stenosis. All 11 patients had an average mid-LV muscular wall thickness of 5 mm. An inverse proportional relationship between the aorto-mitral angle and the incidence of perforation was noted, where in all 11 patients the wire had directed itself towards the anterior free wall of the left ventricle, where it induced injury. A small LV cavity, a hypercontractile state, a thin muscular wall, and a narrow aorto-mitral angle may be considered potential predictors of the occurrence of LV perforation during TAVI.

Perforated peptic ulcer disease continues to inflict high morbidity and mortality. Although patients can be stratified according to their surgical risk, optimal management has yet to be described. In this study we demonstrate a treatment option that improves the mortality among critically ill, poor risk patients with perforated peptic ulcer disease. In our study, two series were retrospectively reviewed: group A patients (n = 522) were treated in a single surgical unit at the Dhaka Medical College Hospital, Dhaka, Bangladesh during the 1980s. Among them, 124 patients were stratified as poor risk based on age, delayed presentation, peritoneal contamination, and coexisting medical problems. These criteria were the basis for selecting a group of poor risk patients (n = 84) for minimal surgical intervention (percutaneous peritoneal drainage) out of a larger group of patients, group B (n = 785) treated at Khulna Medical College Hospital during the 1990s. In group A, 479 patients underwent conventional operative management with an operative mortality of 8.97%. Among the 43 deaths, 24 patients were >60 years of age (55.8%), 12 patients had delayed presentation (27.9%), and 7 patients were in shock or had multiple coexisting medical problems (16.2%). In group B, 626 underwent conventional operative management, with 26 deaths at a mortality rate of 4.15%. Altogether, 84 patients were stratified as poor risk and were managed with minimal surgical intervention (percutaneous peritoneal drainage) followed by conservative treatment. Three of these patients died with an operative mortality of 3.5%. Minimal surgical intervention (percutaneous peritoneal drainage) can significantly lower the mortality rate among a selected group of critically ill, poor risk patients with perforated peptic ulcer disease.

Retrospective Analysis Of CO2 Laser Myringotomy

1988-06-01

A retrospective review of the author's series of 91 carbon dioxide (CO2) laser myringotomy cases performed between 1983 and 1986 is presented. Patients with chronic otitis media with effusion (COME) were selected on the basis of possible benefit from shorter ventilation time than tympanostomy tube insertion. The proceedings were performed on an outpatient basis with topical iontophoretic anesthesia, which offers significant cost savings and a lack of possible complications. The CO2 laser gives clean precise 0.8mm perforations which remain open for 2-4 weeks, this shorter ventilation time minimizing the period of water precautions and other side effects. The laser perforations heal well. With a success rate of 52 % reported, which could be increased with careful patient selection, we feel that the advantages of carbon dioxide laser myringotomy over myringotomy plus intubation outweight the risk of recurrent otitis media with effusion formation in those patients to whom this procedure is applicable.

A method of sealing perforated sinus membrane and histologic finding of bone substitutes: a case report.

Shin, Hong-In; Sohn, Dong-Seok

2005-12-01

To augment the atrophic posterior maxilla, a sinus bone graft has been widely used for sinus floor augmentation. Various bone substitutes have been developed and grafted in the maxillary sinus with and without membranes perforation, although autogenous bone is recommended as a gold standard of grafting materials. Membrane perforation is the most common complication associated with sinus bone graft. To repair a perforation, various methods have been developed. This case report is focused on histologic findings of 1 bovine hydroxyapatite (Bio-Oss; Geistlich Pharma AG, Wolhusen, Switzerland) and 2 kinds of human mineral allograft- Tutoplast cancellous microchips (TutoGen Medical GmbH, Neunkirchen am. Brand Germany), and irradiated allogeniccancellous bone and marrow (ICB; Rocky Mountain Tissue Bank, Aurora, CO) used for sinus graft in the same patient with membrane perforation after various healing periods.

Peptic ulcer in the excluded segment of a gastric bypass performed in the management of morbid obesity has only rarely been reported in the literature. The purpose of this study is to review our experience with the condition in a series of 4300 patients who underwent gastric-restrictive surgery between 1978 and 1997. Eleven patients presented with acute perforation of a peptic ulcer in the excluded gastric segment. Nine ulcers were duodenal, one was gastric, and one patient had both gastric and duodenal perforations. The time between primary gastric-restrictive surgery and ulcer perforation varied from 20 days to 12 years. All patients presented with upper abdominal pain. The classical radiological sign of perforated peptic ulcer, free air under the diaphragm, did not occur in any patient. Nine patients were initially treated by primary closure of the perforation with subsequent definitive ulcer therapy by vagotomy, pyloroplasty, or gastrectomy. One case, initially treated elsewhere, was managed by placement of a Malecot catheter through the duodenal perforation, gastrostomy, and peritoneal drainage. One recent case remains symptom-free on H2 blockers after simple closure. There was no mortality. Six cases were previously reported in the literature with a 33 per cent mortality rate.

Ingested magnets can cause intestinal fistulas, perforation, and obstruction. There have been reports of magnet ingestion causing intestinal volvulus, but multiple magnet ingestion causing perforation and intestinal volvulus in a child is very unusual. We report the case of a 4-year-old girl, who ingested four magnets she acquired as toys, which caused intestinal volvulus and perforation as a result of pressure necrosis, several days after ingestion. At surgery we repaired two perforations, but additional bowel resection was not required. The patient was discharged on postoperative day 10. If multiple magnet ingestion is suspected in a child, the child must be monitored carefully. If there are signs of obstruction, emergency surgery is mandatory.

To assess the role CT in the evaluation of traumatic and spontaneous oesophageal perforation. From March 2001 to May 2003, we studied 12 patients (7 males and 5 females; age range: 25-66 years, mean age: 43.5 years) with suspected oesophageal perforation due to motor-vehicle accidents (4 cases), stab wound (one case), post-intubation (2 cases), foreign body ingestion (2 cases) and spontaneous (3 cases). Five patients underwent standard chest and cervical radiography; two patients with suspected foreign body ingestion also underwent a gastrografin swallow study; all of the 12 patients underwent CT of the neck, chest and abdomen before and after intravenous, and in four cases oral, administration of contrast material. In 5 patients with cervical, thoracic and abdominal trauma, the CT examination showed the presence of pleuroparenchymal injury (pneumothorax, pleural effusion and subcutaneous emphysema) as well as findings suggestive of oesophageal perforation: peri-oesophageal air (5 cases), peri-oesophageal fluid (4 cases), oesophageal wall thickening (3 cases), oesophageal wall laceration (2 cases) with abnormal course of the nasogastric tube in one of them and extraluminal extravasation of oral contrast material (2 cases). In 2 patients with post-intubation complications, CT showed the presence of a small peri-oesophageal fluid collection containing small gas bubbles in one case, and a gross perioesophageal abscess-like collection in the second case. In the 2 patients with foreign body ingestion, the plain radiography associated with CT showed the presence of a thin metal object in the cervical region (fragment of a dental plate) and a small extraluminal extravasation of gastrografin in one case, whereas in the other case CT showed the presence of a foreign body (chicken bone) in the hypopharynx with oesophageal wall thickening and peri-oesophageal oedema. In the remaining three patients with suspected spontaneous oesophageal perforation, CT showed the presence of a intramural haematoma in one case, oesophageal fluid distension with gas and a small peri-oesophageal fluid effusion (Mallory-Weiss syndrome) in another, and oesophageal rupture (Boerhaave syndrome) in the last case. Our experience shows that in patients with suspected traumatic and spontaneous oesophageal perforation, standard cervical and chest radiography may suggest a suspected oesophageal perforation in only a small proportion of cases, whereas oral contrast oesophagography has a higher sensitivity. Through the careful analysis of suggestive and specific signs of oesophageal perforation, a correct CT examination enables an accurate and timely diagnosis which significantly affects prognosis and provides valuable indications for treatment.

Intrauterine contraceptive device (IUCD) is relatively safe but still with some serious risks. Uterus perforation is rare and would be fatal. A case of Cu-7 IUCD invading into the sigmoid colon through uterine perforation caused by a pelvic blunt trauma was presented. Our case showed that uterus perforation by an IUCD could induce utero-sigmoid fistula which is likely to be missed. Imaging is required when the patients with IUCD present abdominal pain, particularly with a history of trauma.

While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis.

Study Design: Multicenter retrospective case series and review of the literature. Objective: To determine the rate of esophageal perforations following anterior cervical spine surgery. Methods: As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients’ charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis. Results: The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired. Conclusions: Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality. PMID:28451488

2014-01-01

A 23-year-old male underwent a left internal jugular vein catheterization during extended surgery for treatment of multiple fractures due to a traffic accident. Although the catheterization was performed under ultrasound (US) guidance, iatrogenic perforation of the central vein and pleura occurred. The catheter was removed, and the perforated site was addressed under thoracoscopy rather than an open thoracotomy. This case suggests that using US does not completely guarantee a complication-free outcome, and that catheter placement should be carefully confirmed. In addition, this case suggests that thoracoscopy may be an ideal method of resolving a perforation of the central vein and pleura. PMID:24851167

Two cases of corneal perforation after oral administration of nonsteroidal anti-inflammatory drugs: oral NSAID-induced corneal damage.

2010-01-01

To report 2 cases of corneal perforation associated with the use of oral nonsteroidal anti-inflammatory drugs (NSAIDs). In a 62-year-old woman and a 79-year-old woman, corneal perforation occurred after 7 days and 5 months of oral NSAIDs administration, respectively. After NSAIDs were discontinued, the cornea epithelialized and the anterior chamber formed within 14 and 10 days, respectively. It is well known that topical NSAIDs cause corneal perforation. Observations in the present cases suggest that the oral administration of NSAIDs may also cause corneal damage, and hence, medical professionals should consider the risk of damage to the cornea when administering these drugs orally.

Perforation is a major complication of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). However, there have been no reports on delayed perforation after ESD for EGC. We aimed to elucidate the incidence and outcomes of delayed perforation after ESD. Clinical courses in 1159 consecutive patients with 1329 EGCs who underwent ESD were investigated. Delayed perforation occurred in six patients (0.45 %). All these patients had complete en bloc resection without intraoperative perforation during ESD. Five of six perforations were located in the upper third of the stomach, while one lesion was found in the middle third. Symptoms of peritoneal irritation with rebound tenderness presented within 24 h after ESD in all cases. One patient did not require surgery because the symptoms were localized, and recovered with conservative antibiotic therapy by nasogastric tube placement. The remaining five patients required emergency surgery. There was no mortality in this case series. © Georg Thieme Verlag KG Stuttgart · New York.

Pharyngoesophageal perforation after anterior cervical spine surgery is rare and the delayed cases were more rarely reported but potentially life-threatening. We report a case of pharyngoesophageal perforation 3 years after anterior cervical spine surgery. The patient presented with dysphagia, fever, left cervical mass and developing dyspnea 3 years after cervical spine surgery for trauma. After careful examinations, he underwent an emergency tracheostomy, neck exploration, hardware removal, abscess drainage and infected tissue debridement. 14 days after surgery, CT of the neck with oral contrast demonstrated no contrast extravasation from the esophagus. Upon review of literature, only 14 cases of pharyngoesophageal perforation more than 1 year after anterior cervical spine surgery were found. We discussed possible etiology, diagnosis and management and concluded that in cases of dysphagia, dyspnea, cervical pain, swelling and edema of the cervical area even long time after anterior cervical spine surgery, potential pharyngoesophageal damage should be considered.

Perforated Meckel's diverticulitis complicating active Crohn's ileitis: a case report.

2009-01-13

In Crohn's disease, the extension of active terminal ileitis into a Meckel's diverticulum is possible, but usually has no impact on clinical decision-making. We describe an original surgical approach in a young woman presenting with a combination of perforated Meckel's diverticulitis and active Crohn's ileitis. We report the case of a 22-year-old woman with Crohn's disease, who was admitted for abdominal pain, fever and diarrhoea. CT scan demonstrated active inflammation of the terminal ileum, as well as a fluid collection in the right iliac fossa, suggesting intestinal perforation. Laparoscopy was performed and revealed, in addition to extensive ileitis, a 3 x 3 cm abscess in connection with perforated Meckel's diverticulitis. It was therefore possible to avoid ileocaecal resection by only performing Meckel's diverticulectomy; pathological examination of the surgical specimen revealed the presence of transmural inflammation with granulomas and perforation of the diverticulum at its extremity. Crohn's disease of the ileum may be responsible for Meckel's diverticulitis and cause perforation which, in this case, proved to be a blessing in disguise and spared the patient an extensive small bowel resection.

2017-04-11

Perforation of a marginal ulcer (MU) is a complication of Roux -en-Y gastric bypass that can be life-threatening. We report a case of a perforated MU that presented 7 months after surgery with several interesting points for discussion. Firstly, the presentation of the ulcer was cryptic with unreliable investigations. Secondly, the ulcer presented again even after anastomotic revision surgery. Finally, the ulcer and the sepsis associated with perforation presented after months of poor nutritional intake with profound hypoalbuminaemia. Perforated MUs causing malnutrition pose clinicians with the difficult decision of which operation to offer; patch repair, revision of the anastomosis or reversal surgery. This case illustrates that primary reversal surgery for a perforated recurrent MU may be the most appropriate surgical management in this clinical situation. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Osteonecrosis related to intraosseous anesthesia: report of a case.

PubMed

Woodmansey, Karl F; White, Robert K; He, Jianing

2009-02-01

Intraosseous anesthesia is an effective and increasingly used technique with few reported complications. The technique uses a specialized drill to perforate the osseous cortex where local anesthetic can then be deposited to anesthetize teeth. It has been reported that separation of the perforation drills from their plastic bases can occur because of the friction generated during osseous perforation. Prolonged rotation of the perforator drills in the bone can also cause excessive heat, which can lead to bone necrosis. This report describes a case of focal osteonecrosis subsequent to intraosseous anesthesia and discusses possible etiologies of this sequela.

A rare case of duodenal ulcer perforation accompanied by Boerhaave syndrome

2015-01-01

Esophageal perforation is the fastest progressing and the most life-threatening disruption of gastrointestinal tract continuity. It must be regarded as an emergency condition that requires early diagnosis as well as very aggressive and rapid implementation of treatment in order to avoid serious complications and death. Methods of treatment for spontaneous esophageal perforation continue to be a matter of controversy. However, all authors emphasize that ultimate success depends largely on the time taken to establish the diagnosis. The authors of this study describe a rare case of duodenal ulcer perforation accompanied by Boerhaave syndrome. PMID:26702287

We discuss the possible role of this surgical maneuver in the management of esophageal perforation.

Comparison of the Multidetector-row Computed Tomographic Angiography Axial and Coronal Planes' Usefulness for Detecting Thoracodorsal Artery Perforators

Kim, Jong Gyu

2012-01-01

Background During the planning of a thoracodorsal artery perforator (TDAP) free flap, preoperative multidetector-row computed tomographic (MDCT) angiography is valuable for predicting the locations of perforators. However, CT-based perforator mapping of the thoracodorsal artery is not easy because of its small diameter. Thus, we evaluated 1-mm-thick MDCT images in multiple planes to search for reliable perforators accurately. Methods Between July 2010 and October 2011, 19 consecutive patients (13 males, 6 females) who underwent MDCT prior to TDAP free flap operations were enrolled in this study. Patients ranged in age from 10 to 75 years (mean, 39.3 years). MDCT images were acquired at a thickness of 1 mm in the axial, coronal, and sagittal planes. Results The thoracodorsal artery perforators were detected in all 19 cases. The reliable perforators originating from the descending branch were found in 14 cases, of which 6 had transverse branches. The former were well identified in the coronal view, and the latter in the axial view. The location of the most reliable perforators on MDCT images corresponded well with the surgical findings. Conclusions Though MDCT has been widely used in performing the abdominal perforator free flap for detecting reliable perforating vessels, it is not popular in the TDAP free flap. The results of this study suggest that multiple planes of MDCT may increase the probability of detecting the most reliable perforators, along with decreasing the probability of missing available vessels.

To characterize patients who suffer perforation in the context of eosinophilic esophagitis (EoE) and to identify predictors of perforation. Esophageal perforation is a serious complication of EoE. We conducted a retrospective cohort study of the University of North Carolina EoE clinicopathologic database from 2001 to 2014. Subjects were included if they had an incident diagnosis of EoE and met consensus guidelines, including nonresponse to a PPI trial. Patients with EoE who had suffered perforation at any point during their course were identified, and compared with EoE cases without perforation. Multiple logistic regression was performed to determine predictors of perforation. Out of 511 subjects with EoE, 10 (2.0%) had experienced an esophageal perforation. Although those who perforated tended to have a longer duration of symptoms before diagnosis (11.4 vs. 7.0 y, P=0.13), a history of food impaction (odds ratio, 14.9; 95% confidence interval, 1.7-129.2) and the presence of a focal stricture (odds ratio, 4.6; 95% confidence interval, 1.1-19.7) were the only factors independently associated with perforation. Most perforations (80%) occurred after a prolonged food bolus impaction, and only half of individuals (5/10) carried a diagnosis of EoE at the time of perforation; none occurred after dilation. Six patients (60%) were treated with nonoperative management, and 4 (40%) required surgical repair. Esophageal perforation is a rare but serious complication of eosinophilic esophagitis, occurring in ∼2% of cases. Most episodes are due to food bolus impaction or strictures, suggesting that patients with fibrostenotic disease due to longer duration of symptoms are at increased risk.

Gallbladder perforation is a serious complication of acute cholecystitis. Its management has evolved considerably since its classification by Niemeier in 1934. This review summarises the evidence surrounding the natural progression of this condition and potential problems with Niemeier's classification, and proposes a management algorithm for the more complex type II perforation. Data from a retrospective case series and a systematic review were combined. The case series included all patients with gallbladder perforations from 2004 to 2008 at a British teaching hospital. The systematic review searched for gallbladder perforation using the MEDLINE, Embase, Web of Science and Cochrane Library (2011 Issue 4) databases, as well as recent conference abstracts. The outcome data were analysed using SPSS version 15. No adjustments were made for multiple testing. 198 patients (including 19 patients from the present series) with a mean age of 62.1+/-9.7 years and male gender proportion of 55.4% (range 33.3-76.7%) were included. The most common gallbladder perforations were type II (median 46.2%, range 7.4-83.3%), followed by type I (median 40.6%, range 16.7-70.0%) and type III (median 10.1%, range 0-48.1%). Perforation was associated with cholelithiasis in 86.6% (range 78.9-90.6%) of patients, and the overall median mortality rate was 10.8% (range 0-12.5%). Male gender was weakly associated with mortality (p = 0.089) but age (p = 0.877) and cholelithiasis (p = 0.425) were not. Mortality did not vary significantly with perforation type. Gallbladder perforation should be reported according to the original Neimeier's classification to avoid heterogeneity in data (e.g. varying rates of perforation types). The algorithm proposed in this study aims to guide the management of complex type II gallbladder perforations to minimise subsequent morbidity and mortality. Copyright © 2012 Surgical Associates Ltd.

Resection of the stomach performed in 85 cases resulted in high postoperative lethality which made up in bleeding ulcers 14.8%. Drainage operations of the stomach with excision or suturing of ulcer combined with bilateral truncal vagotomy was performed in 60 patients, postoperative lethality rate being 8.4%. 128 patients underwent selective proximal vagotomy together with pyloro- and duodenoplasty, lethality rate being 1.6%. Combined vagotomy (posterior truncal and anterior sero-muscular) with excision of ulcer, transversal pyloroplasty and duodenoplasty was carried out in 1036 patients (postoperative lethality--2.4%). Excellent and good functional results were achieved in 79.6% of the patients.

To determine the management of perforated duodenal ulcer at the University Hospital of the West Indies (UHWI) in this era of Helicobacter pylori, the medical records of all patients seen at the UHWI during the period July 1997 to June 2002 with an intra-operative diagnosis of perforated peptic ulcer were reviewed The records were analyzed for the following: age, gender, duration of symptoms, non-steroidal anti-inflammatory drug (NSAID) use, smoking status, operative repair duration of hospitalization, Helicobacter pylori status and medical therapy, peri-operative complications, mortality and recurrence. Ninety per cent of the cases were males. All females in whom perforation occurred were age 50 years and older compared to males where 58% of cases presented before age 50 years. Perforations in acute ulcers occurred in 80% of cases. The majority of patients were male smokers. Non-steroidal anti-inflammatory drug use was also an important risk factor in elderly females. Simple surgical closure and standard triple therapy antibiotics to eradicate Helicobacter pylori was the most common treatment offered. Mortality was one per cent and follow-up poor but 11% of patients had documented recurrent peptic ulceration. In this study population, perforated duodenal ulcer occured overwhelmingly in males less than 50 years of age. There is a trend towards exclusive simple surgical closure and H pylori eradication at the UHWI for patients with perforated duodenal ulcer but this needs to be supported by documentation of H pylori prevalence in the population of patients presenting with perforated peptic ulcers.

Blunt hollow viscus perforations (HVP) due to abdominal contusions (AC), although rare, are difficult to diagnose early and are associated with a high mortality. Our paper analyses retrospectively data from patients operated for HVP between January 2005 and January 2009, the efficiency of different diagnostic tools, mortality and prognostic factors for death. There were 62 patients operated for HVP, 14 of which had isolated abdominal contusion and 48 were poly trauma patients. There were 9 women and 53 men, the mean age was 41.5 years (SD: +17,9), the mean ISS was 32.94 (SD: +15,94), 23 patients had associated solid viscus injuries (SVI). Clinical examination was irelevant for 16 of the 62 patients, abdominal Xray was false negative for 30 out of 35 patients and abdominal ultrasound was false negative for 16 out of 60 patients. Abdominal CT was initially false negative for 7 out of 38 patients: for 4 of them the abdominal CT was repeated and was positive for HVP, for 3 patients a diagnostic laparoscopy was performed. Direct signs for HVP on abdominal CT were present for 3 out of 38 patients. Diagnostic laparoscopy was performed for 7 patients with suspicion for HVP, and was positive for 6 of them and false negative for a patient with a duodenal perforation. Single organ perforations were present in 55 cases, multi organ perforations were present in 7 cases. There were 15 deaths (15.2%), most of them caused by haemodynamic instability (3 out of 6 patients) and associated lesions: SOL for 9 out of 23 cases, pelvic fracture (PF) for 6 out of 14 patients, craniocerebral trauma (CCT) for 12 out of 33 patients.Multivariate analysis showed that the prognostic factors for death were ISS value (p = 0,023) and associated CCT (odds ratio = 4,95; p = 0,017). The following factors were not confirmed as prognostic factors for death: age, haemodynamic instability, associated SVI, thoracic trauma (TT), pelvic fractures (PF), limbs fractures (LF) and admission-operation interval under 6 hours. Hollow viscus perforations due to abdominal contusions have a high mortality, early diagnosis is difficult, repeated abdominal CT and the selective use of diagnostic laparoscopy for haemodynamic stable patients with ambiguous clinical examination and diagnostic imaging are salutary. Prognostic factors for death were the ISS value and associated craniocerebral trauma.

 The supraclavicular artery flap is an excellent flap for head and neck reconstruction. The aim of this study is to assess imaging techniques to define the precise vascular boundaries of this flap.  Six imaging techniques were used for supraclavicular artery mapping in 65 cases; handheld Doppler, triplex ultrasound, computed tomography angiography, magnetic resonance angiography, digital subtraction angiography, and indocyanine green angiography. We checked the site of the perforators, the course of a supraclavicular artery, and anatomical mapping of the supraclavicular artery.  Handheld Doppler identified perforators' sites in 80% of the cases but showed no results for the course of the vessel. Triplex ultrasound identified the site of perforators in 52.9%, and partial mapping of the course of a supraclavicular artery in 64.7% of the cases. Computerized tomography angiography showed the site of perforators in 60%, and the course of supraclavicular artery completely in 45%, and partially in an additional 30%of the cases examined. Magnetic resonance angiography showed negative results for all parameters. Digital subtraction angiography showed the partial course of a supraclavicular artery in 62.5%, but showed no perforators. Indocyanine green angiography showed the site of perforators in 60% and a partial course of supraclavicular artery distal to perforators in 60%.Anatomical mapping of the vessel was possible with computerized tomography angiogram completely in 45%, and partially in 30%, and was also possible with indocyanine green angiography partially in 60%.  Computerized tomography angiography showed best results in the mapping of the supraclavicular artery, but with an inability to define the perforator perfusion territories, and also with risks of irradiation, while indocyanine green angiography is a good alternative as it could precisely map the superficial course of the artery and angiosomes, with no radiation exposure.

Purulent myositis is an acute, intramuscular bacterial infection involving abscess formation most commonly affecting the quadriceps, hamstring and gluteal muscles. We present a case of extensive purulent myositis of the thigh and lower leg caused by bowel perforation below the peritoneal reflection secondary to rectal cancer. Cases of lower limb and perineal purulent myositis should raise suspicion of rectal perforation and should prompt investigations to exclude rectal malignancy.

Iatrogenic aortic valve (AV) perforation during non-aortic cardiac operations is a rare complication. The suture-related inadvertent injury to an AV leaflet can produce leaflet perforation with aortic regurgitation after ventricular septal defect repair (VSDR). We report three consecutive patients who had iatrogenic aortic leaflet perforation during VSDR in other hospitals and referred to our hospital for reoperation. In all three cases, the perforated AV leaflets were preserved and repaired by autologous pericardial patch or direct local closure. PMID:29057770

Introduction Spinal trauma is the cause of high mortality and morbidity, the fall from height as mechanism that can cause a wide variety of lesions, associated both with the direct impact on the ground and with the deceleration. In such fall cases greater heights and higher mortality are involved. Presentation of case We report the successful management of life-threatening hollow-organ perforation following thoracolumbar spinal injury. Discussion Perforation of the hollow-organ in the setting of thoracolumbar trauma may delay the diagnosis and can have devastating consequences. Conclusions This case supports the recommendation for neurosurgeon in the setting of thoracolumbar injury that perforation of the hollow-organ can have devastating consequences. It is vital to achieve an early diagnosis to improve survival rate. PMID:25967553

Central venous catheterization is widely used in patients on hemodialysis. A rare complication associated with the clinical use of central venous catheters is perforation of the heart or major vessels. We report a case of inadvertent perforation of the left atrium and thrombosis after the placement of a hemodialysis catheter in the right internal jugular vein. In such cases, surgical removal of the central venous catheter from perforation sites in the heart and vessel walls poses anesthetic challenges because of the high risk of pneumothorax, hemorrhage, arrhythmias, thrombosis, and death.

Treatment with non-steroidal anti-inflammatory drugs (NSAIDs) is hampered by gastrointestinal ulcer complications, such as ulcer bleeding and perforation. The efficacy of proton-pump inhibitors in the primary prevention of ulcer complications arising from the use of NSAIDs remains unproven. Selective cyclooxygenase-2 (COX-2) inhibitors reduce the risk for ulcer complications, but not completely in high-risk patients. This study determines which patients are especially at risk for NSAID ulcer complications and investigates the effectiveness of different preventive strategies in daily clinical practice. With the use of a nested case-control design, a large cohort of NSAID users was followed for 26 months. Cases were patients with NSAID ulcer complications necessitating hospitalisation; matched controls were selected from the remaining cohort of NSAID users who did not have NSAID ulcer complications. During the observational period, 104 incident cases were identified from a cohort of 51,903 NSAID users with 10,402 patient years of NSAID exposure (incidence 1% per year of NSAID use, age at diagnosis 70.4 ± 16.7 years (mean ± SD), 55.8% women), and 284 matched controls. Cases were characterised by serious, especially cardiovascular, co-morbidity. In-hospital mortality associated with NSAID ulcer complications was 10.6% (incidence 21.2 per 100,000 NSAID users). Concomitant proton-pump inhibitors (but not selective COX-2 inhibitors) were associated with a reduced risk for NSAID ulcer complications (the adjusted odds ratio 0.33; 95% confidence interval 0.17 to 0.67; p = 0.002). Especially at risk for NSAID ulcer complications are elderly patients with cardiovascular co-morbidity. Proton-pump inhibitors are associated with a reduced risk for NSAID ulcer complications.

Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure.

Perforation during colonoscopy is a rare but severe complication. The aim of this study was to assess the time management and laparoscopic therapy of this complication and to evaluate patient outcomes. A retrospective analysis was done on 15 patients operated for a perforation from colonoscopy between January 2000 and December 2006. Three perforations occurred during diagnostic and 12 perforations during interventional colonoscopy. Two perforations occurred as transmural thermal injury to the colon wall. Peritonitis was found in 4 cases and significantly correlated with the mean time between perforation and operation. Twelve perforations were oversewn laparoscopically and 3 perforations were oversewn by laparotomy. After laparoscopic treatment, hospital stay was significantly shorter than after laparotomy. One patient had a postoperative wound infection, mortality was 0%. Laparoscopic oversewing is a safe and effective method in the treatment of perforation from colonoscopy. Optimizing the time range between perforation and laparoscopic therapy results in a better outcome for the patients.

Free perforation is one of the most feared complications of the intestinal tuberculosis. The terminal ileum is the most common site of perforation, while the majority of (90%) perforations are solitary. Herein, we describe a case of a 25-year-old male who presented with generalized peritonitis requiring an emergency exploratory laparotomy, which revealed pan-enteric perforation characterized by multiple perforations of the small bowel extending 10–15 cm from the DJ flexure up to the terminal ileum. The perforations were primarily closed, while 6–8 cm of the diseased terminal ileum was resected and the two ends were brought out as double-barreled ostomy. To the best of our knowledge, such an extensive tuberculous perforation of the small bowel has not been previously reported in the literature before. PMID:26798540

Peritonitis secondary to gut perforation is still one of the commonest surgical emergencies in India and is associated with high morbidity and mortality. The present study examines the aetiology and outcome of peritonitis cases operated on in our surgical unit, and compares our findings with those of previous studies performed between 1981 and 1991. A retrospective study of 260 peritonitis patients operated on in a single surgical unit from 1995 to 2006 was done and data involving clinical presentation, operative findings and post-operative course were studied and analysed. Causes of peritonitis were small bowel perforation (96 ileal, 17 jejunal), peptic perforation (45 duodenal, 16 gastric), appendicular perforation (36), primary peritonitis (8), and others (42). The incidence of major complications was 25% (burst-11%, leak-5%, intraabdominal abscess-5%, multi-organ failure-6.5%). The overall mortality was 10%. High mortality was observed in jejunal, gall bladder and liver abscess perforation cases (> 20%). Histopathological evaluation (143 specimens) revealed tuberculosis in 42 (mostly small bowel), malignancy in 8, and inflammation in the rest. Comparisons with a similar study carried out in the same unit and published in 1995 revealed similar demographic features and mortality, but a change in the most common cause (peptic ulcer perforation to small bowel perforation), and an increased performance of enterostomy compared with primary repair in small bowel perforation and a decrease in the leak rate (13% to 4%). Small bowel perforation is the commonest form of perforation and the mortality rate associated with peritonitis remains unchanged.

Invasive colonic amoebiasis presents primarily with dysentery; colonic perforation occurs rarely. Cases of amoebic colonic perforations have been reported sporadically over the past 20 years. A retrospective study was done in the surgical unit of a tertiary care hospital in North India. The case records of those patients were reviewed who underwent exploratory laparotomy from January 2011 to September 2012 and were diagnosed with amoebic colonic perforation on histopathological examination. Details concerning the clinical presentation, investigations, intraoperative findings, operative procedures, and postoperative outcomes were retrieved. Amongst, a total of 186 emergency exploratory laparotomies carried out during the study, 15 patients of amoebic colonic perforation were identified. The median age of the patients was 42 years (IQR 32.0-58.0) and the male to female ratio was 13:2. Previous history of colitis was present in only 1 patient. The preoperative diagnosis was perforation peritonitis in 12 patients; and intussusception, intestinal obstruction and ruptured liver abscess in 1 patient each. Ten patients had single perforation while 5 had multiple colonic perforations. All the patients except one had perforations in the right colon. Bowel resection was performed depending upon the site and extent of the colon involved-right hemicolectomy (8), limited ileocolic resection (6) and sigmoidectomy (1). Bowel continuity could be restored only in 2 of the 15 patients and a stoma was constructed in the remaining 13 patients. The overall mortality rate was found to be 40% (6/15). Amoebic colonic perforation is associated with unusually high mortality.

INTRODUCTION No consensus exists regarding definitive management of colonic perforation in Ehlers–Danlos syndrome (EDS), with various authors advocating different operative techniques. Spontaneous colonic perforation is a recognised complication of vascular-type EDS (type IV), with many reported cases in the literature. No such cases have been reported concerning classical-type EDS (type I/II). PRESENTATION OF CASE A 55-year-old male with a family history of EDS presented with acute lower abdominal pain and signs of localised peritonitis. Following resuscitation, computerised tomography identified perforation of a sigmoid diverticulum with localised intraperitoneal air. Considering the potential complications associated with laparotomy in a patient with EDS, a trial of conservative management was undertaken including image-guided drainage of a mesenteric abscess. Intensive care monitoring, nutritional support and intravenous antibiotics also facilitated successful non-operative management. Following discharge, molecular studies confirmed COL5A1 mutation, and a diagnosis of classical Ehlers–Danlos syndrome was established. DISCUSSION This is the first reported case of successful conservative management of colonic diverticular perforation in a patient with classical Ehlers–Danlos syndrome. CONCLUSION EDS is highly significant in the surgical context, with the causative genetic factors serving to further complicate the course of surgical intervention. In the absence of consensus regarding best surgical management, due consideration should be given to non-operative management of benign colonic perforation. PMID:24534685

We present a case report regarding a 74-year-old male with iatrogenic esophageal perforation, after an attempt to remove a food bolus impaction at Lannier’s triangle (proximal esophagus). The perforation was treated endoscopically (flexible EGD) by clip application in two sessions, with excellent outcome. Esophageal perforations occur rarely, usually following a medical procedure. The clinical manifestations are often insidious with potentially catastrophic complications. Although the majority of cases have been treated conservatively and/or operatively over the years, there is a rising tendency for non-operative endoscopic interventions due to the high morbidity and mortality rates seen even in specialized units. For this reason self-expandable stents, endoclips, tissue sealants and suturing devices have been used. A high degree of clinical suspicion is essential for successful management of esophageal perforations, as is early decision to intervene and respect for basic surgical principles such as prevention and limitation of extraesophageal contamination, prevention of reflux of gastric contents and restoration of gastrointestinal tract integrity. The published reports on the use of endoclips for repairing perforations of the proximal esophagus are rare. To our knowledge, this is the first case report regarding the endoscopic application of endoclips for the successful closure of an iatrogenic perforation at Lannier’s triangle. PMID:24714287

Closure of the duodenal stump using a stapling device is commonly applied in Roux-en-Y reconstruction after gastrectomy. However, serious and possibly fatal duodenal stump perforation can develop in extremely rare cases. We describe a case of subtotal gastrectomy with Roux-en-Y reconstruction followed by repeated duodenal stump perforations. A 79-year-old man with a long history of diabetes and hypertension was admitted to our institution with epigastralgia and right hypochondralgia. Computed tomography and an upper gastrointestinal imaging series revealed remarkable wall thickening of the gastric antrum and corpus. Upper endoscopy also showed a giant ulcerative lesion in the same area. The lesion was confirmed by histology to be poorly differentiated adenocarcinoma. The patient underwent open subtotal gastrectomy with Roux-en-Y reconstruction. However, duodenal stump perforation occurred repeatedly on postoperative days 1, 3, and 19, which caused peritonitis. The patient was kept alive through duodenal stump repair, an additional resection using a stapling device, and repeated drainage treatments; but he suffered considerable morbidity due to these complications. We report a case of a life-threatening duodenal stump perforation after subtotal gastrectomy, highlighting lessons learned from the profile and clinical course. Abdominal surgeons should be aware of the possibility of this serious complication of duodenal stump perforation, and be able to perform immediate interventions, including life-saving reoperation.

Perforating globe injury is the leading cause of monocular blindness and vision loss. A 58-year-old male was injured by acupuncture needle during acupuncture treatment for his cerebral infarction. To the best of our knowledge, this is the first case report of perforating injury of the eyeball and traumatic cataract caused by acupuncture. The patient was hospitalized due to diagnosis of perforating ocular injury, traumatic cataract, and corneal and iris perforating injury. Moreover, he had to accept treatments of phacoemulsification, anterior vitrectomy along with intraocular lens implantation in the sulcus to improve his visual acuity. As acupuncture therapy has been widely performed for various diseases and achieved highly approval, the aim of this report is to remind acupuncturists operating accurately to avoid unnecessary injury during the treatment process, or the cure can also become the weapon.

The aim of this study is to compare the inlay butterfly transcanal cartilage tympanoplasty with the conventional underlay tympanoplasty. Operation time, pre- and postoperative hearing levels, successful closure rate of tympanic membrane (take rate) and long-term re-perforation in dry perforated chronic otitis media were evaluated. The study design consists of case series with a chart review. The study settings are tertiary referral center. Of the 72 patients (age range 14-57 years) with dry perforated chronic otitis media, 29 patients underwent inlay butterfly transcanal cartilage tympanoplasty (group 1) and 43 patients underwent conventional underlay tympanoplasty without mastoidectomy (group 2) between January 2010 and June 2012. The outcome measures were the duration of surgery, "take rate" at the 30th postoperative day and the audiometric results at the 45th postoperative day. Long-term re-perforation was evaluated at least postoperative 1 year. The graft take rate was 96.5 % in group 1 and 90.7 % in group 2 at the 30th postoperative day (p > 0.05). Mean air-bone gap was improved from 18.8 ± 8.09 to 11.9 ± 7.12 dB in group 1 and from 21.9 ± 7.32 to 11.6 ± 8.43 dB in group 2. The improvement of air-bone gap in both groups was statistically significant (p < 0.05) but the improvement between the groups was not statistically significant (p > 0.05). The average duration of the surgery was 29.9 ± 5.38 min for inlay tympanoplasty group and 58.9 ± 12.1 min for underlay tympanoplasty group (p < 0.05). Two patients in group 2 had re-perforations after an initial take of the graft in 1-year follow-up period. Inlay butterfly transcanal cartilage tympanoplasty is a good choice in selected cases. Although this technique has the similar take rate and audiological results with conventional underlay tympanoplasty, it is a time-saving procedure.

2013-01-01

A liver abscess formation is a rare complication of a gallbladder perforation, with a cholecystohepatic communication. Niemeier, in 1934, classified free gallbladder perforations and generalised biliary peritonitis as an acute or a Type I gallbladder perforation, a pericholecystic abscess and localised peritonitis as a subacute or a Type II gallbladder perforation, and cholecystoenteric fistulas as chronic or Type III gallbladder perforations. We are describing a 50–year–old male patient who presented with right upper quadrant pain and was found to have an intrahepatic perforation of the gallbladder. Our patient had a Type II perforation. We have discussed the diagnostic work-up and the management of this rare entity. Due to the high mortality that can be caused by a delay in making the correct diagnosis, a gallbladder perforation represents a special diagnostic and surgical challenge. PMID:24179927

Purpose To report surgical therapies for corneal perforations in a tertiary referral hospital. Methods Thirty-one eyes of 31 patients (aged 62.4±18.3 years) with surgically treated corneal perforations from January 2002 to July 2013 were included in this study. Demographic data such as cause of corneal perforation, surgical procedures, and visual outcomes were retrospectively analyzed. Results The causes of corneal perforation (n=31) were divided into infectious (n=8, 26%) and noninfectious (n=23, 74%) categories. Infectious causes included fungal ulcer, herpetic stromal necrotizing keratitis, and bacterial ulcer. The causes of noninfectious keratopathy included corneal melting after removal of a metal foreign body, severe dry eye, lagophthalmos, canaliculitis, the oral anticancer drug S-1, keratoconus, rheumatoid arthritis, neurotrophic ulcer, atopic keratoconjunctivitis, and unknown causes. Initial surgical procedures included central large corneal graft (n=17), small corneal graft (n=7), and amniotic membrane transplantation (n=7). In two cases the perforation could not be sealed during the first surgical treatment and required subsequent procedures. All infectious keratitis required central large penetrating keratoplasty to obtain anatomical cure. In contrast, several surgical options were used for the treatment of noninfectious keratitis. After surgical treatment, anatomical cure was obtained in all cases. Mean postoperative best corrected visual acuity was better at 6 months (logMAR 1.3) than preoperatively (logMAR 1.8). Conclusion Surgical therapies for corneal perforations in our hospital included central large lamellar/penetrating keratoplasty, small peripheral patch graft, and amniotic membrane transplantation. All treatments were effective. Corneal perforation due to the oral anticancer drug S-1 is newly reported. PMID:25378903

To explore the clinical effect of the lobulated medial sural artery perforator flap in repairing soft tissue defect in hand or foot. Since March 2012 to September 2014, 6 cases with soft tissue defects in hands or feet were treated by lobulated medial sural artery flaps pedicled with 1st musculo-cutaneous perforator and 2st musculo-cutaneous perforator of the medial sural artery. The size of the flaps ranged from 4.5 cm x 10.0 cm to 6.0 cm x 17.0 cm. 5 cases of lobulated flap survived smoothly, only 1 lobulated flap had venous articulo, but this flap also survived after the articulo was removed by vascular exploration. All flaps had desirable appearance and sensation and the two-point discrimination was 6 mm in mean with 4 to 12 months follow-up (average, 7 months). Linear scar was left in donor sites in 3 cases and skin scar in 3 cases. There was no malfunction in donor sites. Lobulated medial sural artery perforator flap is feasible and ideal method for the treatment of soft tissue defect in hand or foot with satisfactory effect.

Safe procedure in endoscopic submucosal dissection for colorectal tumors focused on preventing complications

2010-01-01

Endoscopic submucosal dissection (ESD) is efficient for en bloc resection of large colorectal tumors. However, it has several technical difficulties, because the wall of the colon is thin and due to the winding nature of the colon. The main complications of ESD comprise postoperative perforation and hemorrhage, similar to endoscopic mucosal resection (EMR). In particular, the rate of perforation in ESD is higher than that in EMR. Perforation of the colon can cause fatal peritonitis. Endoscopic clipping is reported to be an efficient therapy for perforation. Most cases with perforation are treated conservatively without urgent surgical intervention. However, the rate of postoperative hemorrhage in ESD is similar to that in EMR. Endoscopic therapy including endoscopic clipping is performed and most of the cases are treated conservatively without blood transfusion. In blood examination, some degree of inflammation is detected after ESD. For the standardization of ESD, it is most important to decrease the rate of perforation. Adopting a safe strategy for ESD and a suitable choice of knife are both important ways of preventing perforation. Moreover, appropriate training and increasing experience can improve the endoscopic technique and can decrease the rate of perforation. In this review, we describe safe procedures in ESD to prevent complications, the complications of ESD and their management. PMID:20379999

Use of Computed Tomography to Determine Perforation in Patients With Acute Appendicitis.

Urgent appendectomy has long been the standard of care for acute appendicitis. Six randomized trials have demonstrated that antibiotics can safely treat appendicitis, but approximately 1 in 4 of these patients eventually requires appendectomy. Overall treatment success may be limited by complex disease including perforation. Patients׳ success on antibiotic therapy may depend on preoperative identification of complex disease on imaging. However, the effectiveness of computed tomography (CT) in differentiating complex disease including perforated from nonperforated appendicitis remains to be determined. The purpose of this study was to assess the preoperative diagnostic accuracy of CT in determining appendiceal perforation in patients operated for acute appendicitis. We performed a retrospective review of pathology and radiology reports from consecutive patients who presented to the emergency department with suspicion for acute appendicitis between January 2012 and May 2015. CT scans were re-reviewed by abdominal imaging fellowship-trained radiologists using standardized criteria, and the radiologists were blinded to pathology and surgical findings. Radiologists specifically noted presence or absence of periappendiceal gas, abscess, appendicolith, fat stranding, and bowel wall thickening. The overall radiologic impression as well as these specific imaging findings was compared to results of pathology and operative reports. Pathology reports were considered the standard for diagnostic accuracy. Eighty-nine patients (65% male, average age of 34 years) presenting with right lower quadrant pain underwent CT imaging and prompt appendectomy. Final pathology reported perforation in 48% (n = 43) of cases. Radiologic diagnosis of perforation was reported in 9% (n = 8), correctly identifying perforation in 37.5% (n = 3), and incorrectly reporting perforation in 62.5% of nonperforated cases per pathology. Radiology missed 93% (n = 40) of perforations postoperatively diagnosed by pathology. There was no secondary finding (fat stranding, diameter >13mm, abscess, cecal wall thickening, periappendiceal gas, simple fluid collection, appendicolith, and phlegmon) with a clinically reliable sensitivity or specificity to predict perforated appendicitis. Surgeon׳s report of perforation was consistent with the pathology report of perforation in only 28% of cases. The usefulness of a CT for determining perforation in acute appendicitis is limited, and methods to improve precision in identifying patients with complicated appendicitis should be explored as this may help for improving risk prediction for failure of treatment with antibiotic therapy and help guide patients and providers in shared decision-making for treatment options.

Ngo, Christian; Christopoulos, George; Brilakis, Emmanouil S

2016-01-01

Coronary artery perforation is a highly feared complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and can lead to pericardial effusion, tamponade, and, rarely, emergent cardiac surgery. Perforation of epicardial collaterals during retrograde CTO-PCI may be particularly challenging to treat, as embolization from both sides of the perforation may be required to control the bleeding. However, conservative measures can occasionally be effective. We present a case of epicardial collateral vessel perforation that was managed conservatively with anticoagulation reversal.

Malignant gastric lymphoma with spontaneous perforation.

PubMed

Shimada, Satoko; Gen, Tokichi; Okamoto, Hiroyuki

Malignant gastric lymphoma, accounting only for 1% of primary gastric carcinoma, is usually a diffuse large B-cell lymphoma. Toyota et al reported that 37% of gastric perforations involved malignancy, generally gastric carcinoma. Fukuda et al found that less than 5% of malignant gastric lymphomas perforate. While it is relatively well known that perforations often take place during chemotherapy, they are rare in patients not receiving chemotherapy. To our knowledge, spontaneous perforation is rare in gastric malignant lymphoma, having been reported in the Japanese literature only 26 times, including this case, in the last 25 years.

Coronary perforation is a rare complication in patients undergoing percutaneous coronary angioplasty. The mortality of this complication varies depending on factors related to the patient and the procedure performed, reaching 44% in patients with Ellis type III perforation. We report the case of an 81 year old male with multiple cardiovascular risk factors, who underwent percutaneous angioplasty for unstable angina management. The patient developed grade III coronary perforation in the anterior descending artery, which was successfully managed with balloon inflation to 6 atmospheres for 10 minutes twice in the affected area, with an interval of 5 minutes between each dilatation. The patient improved and was discharged.

Radiation therapy can be used to treat Helicobacter pylori-negative or eradication-refractory extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) of the stomach. We report a case of gastric perforation which occurred more than 1 year after the completion of radiotherapy for H. pylori eradication-refractory gastric MALT lymphoma, and then recurred shortly afterwards. This was considered to be a late complication of radiation toxicity. Although gastric perforation due to radiotherapy has been reported very rarely in the past, even in advanced disease, this case shows that perforation can develop in patients with superficial disease and can relapse.

Methods for Solving Gas Damping Problems in Perforated Microstructures Using a 2D Finite-Element Solver

PubMed Central

Veijola, Timo; Råback, Peter

2007-01-01

We present a straightforward method to solve gas damping problems for perforated structures in two dimensions (2D) utilising a Perforation Profile Reynolds (PPR) solver. The PPR equation is an extended Reynolds equation that includes additional terms modelling the leakage flow through the perforations, and variable diffusivity and compressibility profiles. The solution method consists of two phases: 1) determination of the specific admittance profile and relative diffusivity (and relative compressibility) profiles due to the perforation, and 2) solution of the PPR equation with a FEM solver in 2D. Rarefied gas corrections in the slip-flow region are also included. Analytic profiles for circular and square holes with slip conditions are presented in the paper. To verify the method, square perforated dampers with 16–64 holes were simulated with a three-dimensional (3D) Navier-Stokes solver, a homogenised extended Reynolds solver, and a 2D PPR solver. Cases for both translational (in normal to the surfaces) and torsional motion were simulated. The presented method extends the region of accurate simulation of perforated structures to cases where the homogenisation method is inaccurate and the full 3D Navier-Stokes simulation is too time-consuming.

To assess the glove perforation rate, efficacy of double gloving, effect of duration of surgery, expertise of surgeon and operative urgency on the glove perforation rate in obstetrical and gynecologic operations. From February to September 2002, double glove protocol was made necessary for all major obstetrical and gynecologic procedures. The operating surgeon, first and second assistant were included in the study. Gloves damage was noted (overt by inspection, occult by hydroinsufflation technique). Of the 156 procedures included in study, 32 procedures were performed (all emergency operations) single-gloved because surgeons found double gloving clumsy (56%), made it difficult to tie knots due to lack of dexterity (24%), or were too tight (20%). One thousand one hundred and twenty single gloves were examined after each procedure by hydroinsufflation. The overall perforation rate was 13.6% (single versus double outer gloves, 13.8% versus l3.2%, P > 0.05). Matching perforations were found in six cases (4.6%). Thus, the protection offered by double gloves was 95.4% even if the outer gloves were perforated. Four inner gloves had preexisting perforations. Sixty unused gloves checked similarly revealed a perforation rate of 1.6%. Emergency cases had higher perforation rate compared to elective surgeries (16.6% versus 10.8%, P < 0.00 1). Surgeries lasting for more than 40 min had a higher perforation rate compared to those finished in less than or equal to 40 min (18.6% versus 7.6%, P < 0.001). The middle finger of the left hand was the most commonly involved. The surgeon, first assistant and second assistant were involved in 73.6, 23.3 and 3.2% cases, respectively. Double gloving offers considerable protection against exposure to contaminants in the blood and body fluids of the patient and should be made routine, especially in developing countries where HIV, hepatitis B and C are widely prevalent. Double gloving should be made mandatory in emergency procedures, which have a higher perforation rate due to operative urgency, and gloves should be changed in operations lasting for more than 40 min to ensure integrity of barrier.

The endoscopic technique has been utilized to harvest muscle flaps and detect perforators of fasciocutaneous flaps. This study aimed to compare the perioperative outcomes between the endoscope-assisted technique and handheld acoustic Doppler for perforator identification in fasciocutaneous flaps.This retrospective case-control study included patients who underwent fasciocutaneous flap reconstruction for traumatic soft tissue defects. In the case group, perforator identification was assisted by the endoscope-assisted technique. In the control group, age- and sex-matched patients received handheld acoustic Doppler to detect perforators. Perioperative outcomes, flap characteristics, and postoperative complications were compared.There were 12 patients in the case group and 12 in the control group. Compared with the control group, the case group had a significantly shorter length of donor-site wounds (9 cm vs 12 cm, P = .023) and a significantly smaller proportion of patients receiving skin grafting at the donor sites (0% vs 41.7%, P = .037). The case group had a longer operative time, but the difference was not statistically significant (180 minutes vs 150 minutes, P = .367). The amount of blood loss, the time length of postoperative drainage, and complications did not significantly differ between the 2 groups.The endoscope-assisted technique for perforator identification of fasciocutaneous flaps provided less donor-site morbidity and a significantly shorter length of donor-site wounds than the conventional handheld acoustic Doppler, which suggests that this technique could be a valuable alternative when a precise design is indicated.

The use of pre- or postoperative antibiotics in surgery for appendicitis: a systematic review.

2014-03-01

The aim of this study was to review the literature regarding the use of pre- and/or postoperative antibiotics in the management of appendicitis, using data obtained from PubMed and the Cochrane Library. A literature search was conducted using the terms "appendicitis" combined with "antibiotics." Studies were selected based on relevance for the evidence on prophylactic and postoperative treatment with regard to the route and duration of drug administration and the findings of surgery. Patients with acute appendicitis should receive preoperative, broad-spectrum antibiotics. The use of postoperative antibiotics is only recommended in cases of perforation, and treatment should then be given intravenously, for a minimum period of 3-5 days for adult patients, until clinical signs such as fever resolve and laboratory parameters such as C-reactive protein curve and white blood cell (WBC) start to decline. Preoperative antibiotic prophylaxis is recommended in all patients with acute appendicitis, whereas postoperative antibiotics only in cases of perforation.

Early detection of free air in the peritoneal cavity is vital in diagnosis of life-threatening emergencies, and can play a significant role in expediting treatment. We present a series of cases in which bedside ultrasound (US) in the emergency department accurately identified evidence of free intra-peritoneal air and echogenic (dirty) free fluid consistent with a surgical final diagnosis of a perforated hollow viscus. In all patients with suspected perforated viscus, clinicians were able to accurately identify the signs of pneumoperitoneum including enhanced peritoneal stripe sign (EPSS), peritoneal stripe reverberations, and focal air collections associated with dirty shadowing or distal multiple reflections as ring down artifacts. In all cases, hollow viscus perforation was confirmed surgically. It seems that, performing US in patients with suspected perforated viscus can accurately identify presence of intra-peritoneal echogenic or "dirty" free fluid as well as evidence of free air, and may expedite patient management.

Perforating globe injury is the leading cause of monocular blindness and vision loss. A 58-year-old male was injured by acupuncture needle during acupuncture treatment for his cerebral infarction. To the best of our knowledge, this is the first case report of perforating injury of the eyeball and traumatic cataract caused by acupuncture. The patient was hospitalized due to diagnosis of perforating ocular injury, traumatic cataract, and corneal and iris perforating injury. Moreover, he had to accept treatments of phacoemulsification, anterior vitrectomy along with intraocular lens implantation in the sulcus to improve his visual acuity. As acupuncture therapy has been widely performed for various diseases and achieved highly approval, the aim of this report is to remind acupuncturists operating accurately to avoid unnecessary injury during the treatment process, or the cure can also become the weapon.

There is lack of anatomical information regarding cutaneous perforator of the popliteal artery and its connections with the descending branch of the inferior gluteal and profunda femoris arteries. We aimed to evaluate the anatomical basis of popliteal artery perforator-based propeller flap from the posterior thigh region and to demonstrate our experience utilizing this flap. Ten fresh cadaveric lower extremities were dissected following injection of a silicone compound into the femoral artery. We investigated the number, location, length, and diameter of cutaneous perforators of the popliteal artery. Based on the results, we treated three cases with a large soft tissue defect around the knee using popliteal artery perforator-based propeller flap. We found a mean of 1.9 cutaneous perforators arising from the popliteal artery with a mean pedicle length of 6 cm and a mean arterial internal diameter of 0.9 mm, which were located at an average of 4 cm proximal to the bicondylar line. The most distal perforator consistently arose along the small saphenous vein and connected proximally with concomitant artery of the posterior femoral cutaneous nerve, forming a connection with perforating arteries of the profunda femoris artery. A mean of 4.5 cutaneous perforators branched from the arterial connection sites. All clinical cases healed without any complications. The popliteal artery perforator-based propeller flap is reliable for reconstruction of soft tissue defects around the knee. The flap should include the deep fascia and concomitant artery along with the posterior femoral cutaneous nerve for maintaining the blood supply.

Perforation peritonitis is the most common surgical emergency encountered by surgeons all over the world as well in India. The spectrum of etiology of perforation peritonitis in tropical countries continues to differ from its western counterpart. This study was conducted at Hindu Rao Hospital, Municipal Corporation of Delhi, New Delhi, India, designed to highlight the spectrum of perforation peritonitis in the eastern countries and to improve its outcome. This prospective study included 77 consecutive patients of perforation peritonitis studied in terms of clinical presentations, causes, site of perforation, surgical treatment, postoperative complications, and mortality at Hindu Rao Hospital, Delhi, from March 1, 2011 to December 1, 2011, over a period of 8 months. All patients were resuscitated and underwent emergency exploratory laparotomy. On laparotomy cause of perforation peritonitis was found and controlled. The most common cause of perforation peritonitis noticed in our series was perforated duodenal ulcer (26.4 %) and ileal typhoid perforation (26.4 %), each followed by small bowel tuberculosis (10.3 %) and stomach perforation (9.2 %), perforation due to acute appendicitis (5 %). The highest number of perforations was seen in ileum (39.1 %), duodenum (26.4 %), stomach (11.5 %), appendix (3.5 %), jejunum (4.6 %), and colon (3.5 %). Overall mortality was 13 %. The spectrum of perforation peritonitis in India continuously differs from western countries. The highest number of perforations was noticed in the upper part of the gastrointestinal tract as compared to the western countries where the perforations seen mostly in the distal part. The most common cause of perforation peritonitis was perforated duodenal ulcer and small bowel typhoid perforation followed by typhoid perforation. Large bowel perforations and malignant perforations were least common in our setup.

The musculocutaneous tensor fascia latae flap was one of the first free flaps described. It is possible to harvest a flap with the same skin paddle, vascularized by a septo-cutaneous perforator running through the tensor fascia lata muscle septum and coming from the ascending branch of the lateral circumflex femoral artery. The DIEP is currently the workhorse of autologous breast reconstruction, but there are some contraindications. The septo-cutaneous tensor fascia latae perforator flap may be an alternative for women with lateral upper thigh lipodystrophy. Between 2010 and 2014, three flaps have been performed in two patients for delayed breast reconstruction (one case of unilateral reconstruction, and one bilateral). Perforators were identified by preoperative angiography. The intervention was performed in a two-team approach, in only one operative position. Perforators were located in the horizontal axis of the upper rim of the pubis bone. One perforator artery was dissected for each flap. The mean caliber of the pedicle was 2.8mm, and the mean length was 6.4cm. The operative time was 240minutes for unilateral flap, 375minutes for bilateral flap. There was no case of total or partial necrosis, or complications on the donor site. Cosmetic results were considered satisfying by patients and surgeons with the reconstructed breast as well as the donor site. Septo-cutaneous fascia lata perforator flap is an attractive flap for breast reconstruction in patients with DIEP contraindication and lateral upper thigh lipodystrophy. It has many advantages: easy to harvest, length and calibre of the pedicle, double team approach, only one operating position, quality of reconstruction. It is necessary to carry out a larger series of cases to study the complication rate in the donor site. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Peritonitis due to gastroduodenal ulcer perforation disease is a rare entity in pediatric surgery. In Senegal, no study has been dedicated to ulcer complications in children. The aim of this study was to describe the epidemiology, diagnosis, and treatment of perforated peptic ulcer in patients less than 15 years old. This retrospective study was conducted in the Surgical Emergencies and Paediatric Surgery Department at Aristide Le Dantec University Hospital Center in Dakar, Senegal, during a period of 11 years (January 1999 to December 2010). We found 4 children who presented perforated gastroduodenal ulcer: 3 females and 1 male. The average age of these patients was 9 years (range, 7-14 years). No family history was found. We noted 3 cases of perforated duodenal ulcer and one perforated gastric ulcer. The clinical diagnosis was suspected based on a peritoneal irritation syndrome. A plain x-ray of the abdomen was taken in all patients, which objectified a pneumoperitoneum image in 3 cases. The leukocytosis was constant. Treatment in all patients consisted on pre-, intra-, and postoperative intensive care, supra- and infraumbilical midline laparotomy, which allowed us to perform a debridement-suture of the gap followed by epiploplasty and extensive washing with lukewarm physiologic serum. Adjuvant therapy based on anti-ulcer and antibiotic therapy was initiated. Bacteriological examination of peritoneal fluid isolated a polymicrobial flora. Helicobacter pylori was not isolated. Histological examination of the biopsied perforation edges showed a benign ulcer in all cases. The follow-up endoscopy was performed 4 weeks after surgery and showed cicatrization of the ulcer in all patients. After a mean of 2 years, no recurrence was noted. The gastric or duodenal ulcer in children is rare. It is often discovered at the stage of perforation, a complication for which the essential treatment is surgery. Routine screening would certainly help to reduce the risk of this complication. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

The ingestion of a foreign body is relatively common. However, it rarely results in the perforation of gastrointestinal tract. We herein report an unusual case of malignant lymphoma incidentally diagnosed after the perforation of the small intestine by a fish bone. A 90-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Abdominal computed tomography demonstrated free air and ascites in the abdominal cavity. In the pelvic cavity, a radiopaque linear shadow about 35mm in diameter was shown in the small intestine, and the stricture was exposed to the abdominal cavity. Therefore, a diagnosis of perforation of the small intestine due to ingestion of a foreign body and panperitonitis was made. Emergent laparotomy was performed. The intraoperative findings revealed perforation of the small intestine with a fish bone in the jejunum. Local inflammation at the perforation site was seen, and circulated wall thickness was observed at the distal side of the jejunum. Partial resection of the jejunum and anastomosis of jejuno-jejunostomy was performed. A pathological examination and immunohistochemical study of the resected specimen resulted in a diagnosis of malignant lymphoma of follicular lymphoma Grade 1. It is very difficult to identify the existence malignancy accompanied with gastrointestinal perforation with ingestion of a foreign body. In cases suspected of involving malignancy, careful observation during surgery is needed in order to avoid missing the accompanying malignancy. Copyright © 2017 The Authors.

This study investigates the safety and accuracy of percutaneous pedicle screws placed using fluoroscopic guidance in the thoracolumbosacral spine among Asian patients. Computerized tomography scans of 128 patients who had surgery using fluoroscopic-guided percutaneous pedicle screws were selected. Medial, lateral, superior, and inferior screw perforations were classified into grade 0 (no violation), grade 1 (<2 mm perforation), grade 2 (2-4 mm perforation), and grade 3(>4 mm perforation). Anterior perforations were classified into grade 0 (no violation), grade 1 (<4 mm perforation), grade 2 (4-6 mm perforation), and grade 3(>6 mm perforation). Grade 2 and grade 3 perforation were considered as "critical" perforation. In total, 1002 percutaneous pedicle screws from 128 patients were analyzed. The mean age was 52.7 ± 16.6. There were 70 male patients and 58 female patients. The total perforation rate was 11.3% (113) with 8.4% (84) grade 1, 2.6% (26) grade 2, and 0.3% (3) grade 3 perforations. The overall "critical" perforation rate was 2.9% (29 screws) and no complications were noted. The highest perforation rates were at T4 (21.6%), T2 (19.4%), and T6 (19.2%). The total perforation rate of 11.3% with the total "critical" perforation rate of 2.9% (2.6% grade 2 and 0.3% grade 3 perforations). The highest perforation rates were found over the upper to mid-thoracic region. Fluoroscopic-guided percutaneous pedicle screws insertion among Asians has the safety and accuracy comparable to the current reported percutaneous pedicle screws and open pedicle screws techniques.

Usually, anterolateral thigh (ALT) defects with width more than 8 cm cannot be closed directly. Although several methods of using local flaps exist, flap mobility of these methods is limited. We introduced a perforator-based propeller flap for such reconstruction. Their maximal mobility, which minimizes their size, is their greatest advantage. In addition, we present our technical refinements including double-axes propeller flap, the use of indocyanine green real-time angiography, and supercharged propeller flap for safer flap transfer. Seven patients underwent perforator-based propeller flap reconstruction of ALT defects. Flaps were designed cranial or caudal to the defect according to the perforator locations. To maximize mobility, flaps were designed so that the perforator was located at the periphery and closer to the defect. After rotating the flap to the defect, indocyanine green angiography was performed to determine the need for supercharge. In all cases, all flaps survived completely. Defect size ranged from 12 × 11 cm to 18 × 16 cm, and flap size ranged from 7 × 5 cm to 15 × 7 cm. The number of perforators in the flap was 1 in 3 cases and 2 in 4 cases. Supercharging was performed in 3 cases. Donor-site complications, including gait disturbance, were not observed. This method achieves ALT defect closure with minimal donor-site morbidity and can provide prompt and aesthetically acceptable results. Indocyanine green real-time angiography and supercharging technique are also useful for safer and reliable flap transfer.

To report a case of nontraumatic corneal perforation managed with a tectonic drape patch. Interventional case report. A 60-year-old patient with a corneal scar in his left eye likely secondary to herpes simplex virus interstitial keratitis underwent laser peripheral iridotomy for narrow angles. He developed progressive thinning of the cornea overlying the scar that led to a descemetocele and then ultimately a 1.2- × 1.7-mm perforation. Intraoperatively, several attempts were made to seal the perforation with cyanoacrylate glue, but the wound continued to leak. Sterile plastic drape that was on the surgical field was fashioned into a 2-mm-diameter patch, and the peripheral edge of the tectonic drape patch was glued over the perforation, successfully sealing the cornea. One week later, the drape patch was intact without leak, and a penetrating keratoplasty was carried out without complication. Tectonic drape patch technique for nontraumatic corneal perforations in which there is tissue loss is a viable temporizing option when cyanoacrylate glue alone fails and when there is no corneal tissue or amniotic membrane available to close the wound.

Endoscopic duodenal perforation: surgical strategies in a regional centre

PubMed Central

2014-01-01

Background Duodenal perforation is an uncommon complication of endoscopic retrograde cholangio-pancreatography (ERCP) and a rare complication of upper gastrointestinal endoscopy. Most are minor perforations that settle with conservative management. A few perforations however result in life-threatening retroperitoneal necrosis and require surgical intervention. There is a relative paucity of references specifically describing the surgical interventions required for this eventuality. Methods Five cases of iatrogenic duodenal perforation were ascertained between 2002 and 2007 at Cairns Base Hospital. Clinical features were analyzed and compared, with reference to a review of ERCP at that institution for the years 2005/2006. Results One patient recovered with conservative management. Of the other four, one died after initial laparotomy. The other three survived, undergoing multiple procedures and long inpatient stays. Conclusions Iatrogenic duodenal perforation with retroperitoneal necrosis is an uncommon complication of endoscopy, but when it does occur it is potentially life-threatening. Early recognition may lead to a better outcome through earlier intervention, although a protracted course with multiple procedures should be anticipated. A number of surgical techniques may need to be employed according to the individual circumstances of the case. PMID:24461069

To define the clinical characteristics, and to assess the management of colonoscopic complications at a local clinic. A retrospective review of the medical records was performed for the patients with iatrogenic colon perforations after endoscopy at a local clinic between April 2006 and December 2010. Data obtained from a tertiary hospital in the same region were also analyzed. The underlying conditions, clinical presentations, perforation locations, treatment types (operative or conservative) and outcome data for patients at the local clinic and the tertiary hospital were compared. A total of 10  826 colonoscopies, and 2625 therapeutic procedures were performed at a local clinic and 32  148 colonoscopies, and 7787 therapeutic procedures were performed at the tertiary hospital. The clinic had no perforations during diagnostic colonoscopy and 8 (0.3%) perforations were determined to be related to therapeutic procedures. The perforation rates in each therapeutic procedure were 0.06% (1/1609) in polypectomy, 0.2% (2/885) in endoscopic mucosal resection (EMR), and 3.8% (5/131) in endoscopic submucosal dissection (ESD). Perforation rates for ESD were significantly higher than those for polypectomy or EMR (P < 0.01). All of these patients were treated conservatively. On the other hand, three (0.01%) perforation cases were observed among the 24  361 diagnostic procedures performed, and these cases were treated with surgery in a tertiary hospital. Six perforations occurred with therapeutic endoscopy (perforation rate, 0.08%; 1 per 1298 procedures). Perforation rates for specific procedure types were 0.02% (1 per 5500) for polypectomy, 0.17% (1 per 561) for EMR, 2.3% (1 per 43) for ESD in the tertiary hospital. There were no differences in the perforation rates for each therapeutic procedure between the clinic and the tertiary hospital. The incidence of iatrogenic perforation requiring surgical treatment was quite low in both the clinic and the tertiary hospital. No procedure-related mortalities occurred. Performing closure with endoscopic clipping reduced the C-reactive protein (CRP) titers. The mean maximum CRP titer was 2.9 ± 1.6 mg/dL with clipping and 9.7 ± 6.2 mg/dL without clipping, respectively (P < 0.05). An operation is indicated in the presence of a large perforation, and in the setting of generalized peritonitis or ongoing sepsis. Although we did not experience such case in the clinic, patients with large perforations should be immediately transferred to a tertiary hospital. Good relationships between local clinics and nearby tertiary hospitals should therefore be maintained. It was therefore found to be possible to perform endoscopic treatment at a local clinic when sufficient back up was available at a nearby tertiary hospital.

2003-06-01

The purposes of this prospective study were to verify the frequency of glove perforation during gynecological operations and to evaluate the efficacy of double gloving in preventing damage to the inner glove. From May 2000 to May 2001, three house staff and 12 residents were asked to place their used gloves in bags labeled with the following information: procedure performed, presence of a recognized glove perforation, and role in operating team (surgeon, first or second assistant, and instrumentalist). All glove sets were tested using the method of water pression. Damaged gloves were excluded from that analysis. In all, 35 and 51 operations were utilized with single and double gloves, respectively. There were 240 single gloves and 792 double gloves tested. Perforation occurred in 10.4% of the single gloves and 9.8% of the outer double gloves. There were no cases of perforation in the inner double gloves. In cases of operating time that lasted more than 2 h, 56% of the surgeries that used single gloves had perforation vs 58.5% of the double gloves. The first assistant had the major risk for glove perforation with the use of single or double gloves. The indicator finger of the non-dominant hand was the major risk for perforation. In conclusion, we recommend double gloving in all gynecological surgery to reduce the risk of contracting blood-borne diseases.

A case of gastric perforation caused by chestnut bezoars.

Okagawa, Yutaka; Takada, Kohichi; Arihara, Yohei; Kato, Junji

A 65-year-old man was admitted under emergency to our hospital because of abdominal pain. His current medication history did not include steroids or nonsteroidal antiinflammatory drugs. He had taken an eradication agent for Helicobacter pylori, and his serum was negative for H. pylori IgG antibody. Abdominal computed tomography indicated gastric perforation;therefore, emergency surgery was performed. Two weeks later, esophagogastroduodenoscopy revealed a gastric ulcer on the lesser curvature of the gastric angle and bezoars. The gastric perforation was thought to be caused by the bezoars. The bezoars were successfully treated with endoscopic therapy using Coca-Cola ® . The bezoars included over 98% tannin, and the patient had frequently consumed chestnuts. We thus diagnosed a rare case of gastric perforation caused by chestnut bezoars.

Primary omental torsion is a rare cause of acute abdomen in adults and presents with variable signs and symptoms. Establishing a preoperative diagnosis may be difficult in the emergency setting. It is rarely diagnosed preoperatively as it mimics common surgical emergencies such as acute appendicitis, appendicular perforation, acute cholecystitis and perforated peptic ulcers and can lead to the clinical deterioration of patient if missed A 47 years old male was taken to the operating room with a diagnosis of appendicular perforation peritonitis and during surgery was found to have a primary omental gangrene with pyoperitoneum, for which omentectomy and peritoneal lavage was performed. Torsion of the omentum is a condition in which the organ twists on its long axis to such an extent that its vascularity is compromised. Omental torsion can be primary (idiopathic) or secondary, depending on an underlying cause. Primary omental torsion was first described by Eitel in 1899. However, very few cases have been reported. Our case was a rare case presenting with omental gangrene with pyoperitoneum mimicking appendicular perforation peritonitis. Primary omental torsion is a rare diagnosis. A high index of clinical suspicion is required for a preoperative diagnosis. In doubtful cases a CT scan may be helpful. Surgical excision of the omentum remains the treatment of choice; however, conservative management may be attempted in an uncomplicated omental torsion. Copyright © 2016 The Authors.

There are numerous cases of abdominal injuries due to bullets. Abdominal injuries due to bullets are a diagnostic and therapeutic challenge. Here, an unusual case of an abdominal perforation caused by a metal projectile, lead to confusion in the interpretation of the preoperative computer tomography. We present an unusual case of a 32-year-old male worker who sustained a "shot" to the left upper abdominal quadrant, as a result of a work-related accident. The projectile derived from a special wire that tore during operation. One chain element happened to accelerate towards the patients belly and perforated the abdominal wall. Computer tomography located the radiopaque projectile to the cortex of the left kidney and showed a lesion of the tail of the pancreas. The presence of intraperitoneal free air suggested a gastrointestinal perforation. Immediate open exploration of the peritoneal cavity and the retroperitoneal space revealed perforating lesions of the anterior and posterior gastric wall, as well as the pancreatic tail. The projectile was finally retrieved in the upper pole of the left kidney. The patient had a good clinical course subsequent to surgery and was discharged in good general condition. This case represents a rare form of a retained bullet injury and corroborates the need of sufficient measures of worker-protection in area of diamond-studded wire cutting devices.

Perforation peritonitis is the most common surgical emergency encountered by the surgeons all over the world as well in Pakistan. The spectrum of etiology of perforation peritonitis in tropical countries continues to differ from its western counter part. This study was conducted at Dow University of health sciences and Civil Hospital Karachi (DUHS & CHK) Pakistan, designed to highlight the spectrum of perforation peritonitis in the East and to improve its outcome. A prospective study includes three hundred consecutive patients of perforation peritonitis studied in terms of clinical presentations, Causes, site of perforation, surgical treatment, post operative complications and mortality, at (DUHS&CHK) Pakistan, from 1st September 2005 - 1st March 2008, over a period of two and half years. All patients were resuscitated underwent emergency exploratory laparotomy. On laparotomy cause of perforation peritonitis was found and controlled. The most common cause of perforation peritonitis noticed in our series was acid peptic disease 45%, perforated duodenal ulcer (43.6%) and gastric ulcer 1.3%. followed by small bowel tuberculosis (21%) and typhoid (17%). large bowel perforation due to tuberculosis 5%, malignancy 2.6% and volvulus 0.3%. Perforation due to acute appendicitis (5%). Highest number of perforations has seen in the duodenum 43.6%, ileum37.6%, and colon 8%, appendix 5%, jejunum 3.3%, and stomach 2.3%. Overall mortality was (10.6%). The spectrum of perforation peritonitis in Pakistan continuously differs from western country. Highest number of perforations noticed in the upper part of the gastrointestinal tract as compared to the western countries where the perforations seen mostly in the distal part. Most common cause of perforation peritonitis is perforated duodenal ulcer, followed by small bowel tuberculosis and typhoid perforation. Majority of the large bowel perforations are also tubercular. Malignant perforations are least common in our setup.

Peptic ulcer is a common disease affecting millions of people every year. Despite improved understanding and treatment of the disease, the number of patients admitted with duodenal peptic ulcer perforation has not decreased. Deaths from peptic ulcer disease overcome other common emergency situations. Laparoscopic repair of the perforated peptic ulcer (PPU) is the gold standard approach for simple perforation. However, in patients with large perforated chronic ulcers laparotomy with pyloroplasty is the standard treatment. It is generally accepted to perform open surgery in PPU emergencies because of the greater knowledge and experience gathered over the past decades and less potential harm for the patient or surgical complications. We present a case of successful laparoscopic pyloroplasty of a perforated duodenal ulcer with stenosis.

The utilization of esophagogastroduodenoscopy (EGD) and related procedures continues to rise. Due to this increase in utilization is an inevitable rise in serious complications such as hemorrhage and perforation. One understudied and dreaded complication of EGD causing significant morbidity and mortality is duodenal perforation. We present the case of a 63-year-old male who presented to our institution's emergency room with dyspepsia, melanic stools, tachycardia, and hypotension. Initial laboratory evaluation was significant for severe anemia, lactic acidosis, and acute kidney injury, while CT scan of the abdomen pelvis did not suggest retroperitoneal hematoma or bowel perforation. An emergent EGD was performed which showed multiple bleeding duodenal ulcers that were cauterized and injected with epinephrine. Post-procedure the patient developed worsening abdominal pain, distension, diaphoresis, and tachypnea, requiring emergent intubation. A CT scan of the abdomen and pelvis with oral contrast confirmed pneumoperitoneum and duodenal perforation. Due to the patient's hemodynamic instability and multiple comorbidities, he was treated non-operatively with strict bowel rest and intravenous antibiotics. The patient ultimately had a 19-day hospital course complicated by renal failure requiring hemodialysis and an ischemic limb necessitating above knee amputation. This case describes an unsuccessful attempt at nonoperative management of duodenal perforation following EGD. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Surgical management of peptic ulcer disease today--indication, technique and outcome.

PubMed

Zittel, T T; Jehle, E C; Becker, H D

2000-03-01

The current surgical management of peptic ulcer disease and its outcome have been reviewed. Today, surgery for peptic ulcer disease is largely restricted to the treatment of complications. In peptic ulcer perforation, a conservative treatment trial can be given in selected cases. If laparotomy is necessary, simple closure is sufficient in the large majority of cases, and definitive ulcer surgery to reduce gastric acid secretion is no longer justified in these patients. Laparoscopic surgery for perforated peptic ulcer has failed to prove to be a significant advantage over open surgery. In bleeding peptic ulcers, definitive hemostasis can be achieved by endoscopic treatment in more than 90% of cases. In 1-2% of cases, immediate emergency surgery is necessary. Some ulcers have a high risk of re-bleeding, and early elective surgery might be advisable. Surgical bleeding control can be achieved by direct suture and extraluminal ligation of the gastroduodenal artery or by gastric resection. Benign gastric outlet obstruction can be controlled by endoscopic balloon dilatation in 70% of cases, but gastrojejunostomy or gastric resection are necessary in about 30% of cases. Elective surgery for peptic ulcer disease has been largely abandoned, and bleeding or obstructing ulcers can be managed safely by endoscopic treatment in most cases. However, surgeons will continue to encounter patients with peptic ulcer disease for emergency surgery. Currently, laparoscopic surgery has no proven advantage in peptic ulcer surgery.

Pediatric appendicitis is a common, potentially serious condition. Determining perforation status is crucial to planning effective management. Determine the efficacy of serum total bilirubin concentration [STBC] in distinguishing perforation status in children with appendicitis. Retrospective review of 257 cases of appendicitis who received abdominal CT scan and measurement of STBC. There were 109 with perforation vs 148 without perforation. Although elevated STBC was significantly more common in those with [36%] vs without perforation [22%], the mean difference in elevated values between groups [0.1mg/dL] was clinically insignificant. Higher degrees of hyperbilirubinemia [>2mg/dL] were rarely encountered [5%]. Predictive values for elevated STBC in distinguishing perforation outcome were imprecise [sensitivity 38.5%, specificity 78.4%, PPV 56.8%, NPV 63.4%]. ROC curve analysis of multiple clinical and other laboratory factors for predicting perforation status was unenhanced by adding the STBC variable. Specific analysis of those with perforated appendicitis and percutaneously-drained intra-abdominal abscess which was culture-positive for Escherichia coli showed an identical rate of STBC elevation compared to all with perforation. The routine measurement of STBC does not accurately distinguish perforation status in children with appendicitis, nor discern infecting organism in those with perforation and intra-abdominal abscess.

Anomalies of the fetal urachus are rare. Normally, the postnatal urachus presents as a fibrous band extending from the bladder to the umbilicus. Urachal cysts may occur in postnatal life. Spontaneous perforation of urachal cysts is a very rare condition, which clinically may not be distinguishable from other acute abdominal conditions. We report a case of a 63-year-old male with a history of recurrent urinary tract infections and a bladder rupture caused by a spontaneous perforation of an infected urachal cyst. The symptomatology showed abdominal rigidity and pain, a palpable mass in the lower abdomen, and hematuria. Laboratory findings showed leukocytosis and an increased CRP level. The bladder rupture was confirmed by cystography. Bacteriologic examination identified Proteus vulgaris, Corynebacterium species, and Klebsiella pneumoniae. Most of the published cases in the literature report about intraperitoneal perforation of infected urachal cysts. In the present case, we found a spontaneous perforation of an infected urachal cyst leading to an extraperitoneal bladder rupture with an extraperitoneal limitation of the infection. The definitive therapy was complete surgical excision including a cuff of the bladder, drainage, and systemic broad-spectrum and local application of antibiotics. The further course was uneventful.

Gallbladder perforation is an unusual condition with a high mortality rate. Early detection with prompt surgical intervention can increase the survival rate. Hepatobiliary imaging using Technetium-99m-labeled iminodiacetic acid has been used for the diagnosis of gallbladder perforation. However, the results vary and are somewhat confusing. The authors report a case of gallbladder perforation with hepatobiliary imaging and an unusual gallium image; review the literature; and propose a classification of three different imaging patterns: (1) visualization of the gallbladder with bile leakage, (2) nonvisualization of the gallbladder with a photopenic fluid collection, and (3) nonvisualization of the gallbladder with bile leakage.more » These patterns may provide pathophysiologic information for the surgeon. 27 references.« less

Glove perforation in hip and knee arthroplasty.

2010-11-01

The transmission of blood-borne pathogens during surgery is a major concern. Surgical gloves are the primary barrier between the surgeon and the patient. Surgical procedures that need manual handling of bony surfaces or sharp instruments have the highest risk of glove perforations. The frequencies and the sites of surgical glove perforations in arthroplasty procedures were assessed. We assessed the surgical glove perforations in total hip and knee arthroplasty procedures. Double standard latex gloves were used. A total of 983 outer and 511 inner gloves were tested. The gloves of all the surgical team members were tested for perforations during the first and second hours of surgery. There were 18.4% outer and 8.4% inner glove perforations. The most frequent site of perforation was the second digit of the nondominant hand (25.5%). We found that hip and knee arthroplasty had significantly more glove perforation risk for the surgeon in the first half of the operation rather than the second half, and 57.8% of the perforations were at the index finger and the thumb. Arthroplasty procedures still have high glove perforation rates despite the use of double gloving with frequent changes. Extra augmentation of the gloves in selected areas of the hand, in addition to double gloving, may be safer and more cost-effective than double gloving alone.

Acute appendicitis is the most common non-obstetric reason of abdominal pain in the pregnancy, causing significant increase of maternal and fetal morbidity and mortality. This is a case report of a patient in the third trimester of pregnancy in whom perforated appendicitis caused purulent peritonitis. She was operated as an emergency case and cesarean section was performed. After the surgery and antibiotic administration according to drug susceptibility test, her postoperative course was uneventful. Delayed diagnosis of the acute appendicitis leads to increased rate of appendicular perforation, with numerous maternal and fetal complications. In cases of suspected appendicitis during pregnancy, surgical exploration is indicated, either by laparoscopy or laparotomy. Laparotomy is the method of choice in cases after 20 weeks of pregnancy and whenever signs of diffuse peritonitis are present.

Esophageal perforation has a high mortality rate. Fluoroscopic esophagography (FE) is the procedure of choice for diagnosing esophageal perforation. However, FE can be difficult to perform in seriously ill patients. We retrospectively reviewed charts and scans of all patients who had undergone thoracic CT (TCT) without oral contrast and FE for suspicion of esophageal perforation at our hospital between October, 2010 and December, 2015. Scans were interpreted by a single consultant radiologist having > 5 years of relevant experience. Statistical analysis was performed using SPSS version 20. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of TCT were computed using FE as reference standard. Of 122 subjects, 106 (83%) were male and their median age was 42 [inter-quartile range (IQR) 29-53] years. Esophageal perforation was evident on FE in 15 (8%) cases. Sensitivity, specificity, PPV and NPV of TCT for detecting esophageal perforation were 100, 54.6, 23.4 and 100%, respectively. When TCT was negative (n = 107), an alternative diagnosis was evident in 65 cases. Thoracic computed tomography (TCT) had 100% sensitivity and negative predictive value for excluding esophageal perforation. FE may be omitted in patients who have no evidence of mediastinal collection, pneumomediastinum or esophageal wall defect on TCT. However, in the presence of any of these features, FE is still necessary to confirm or exclude the presence of an esophageal perforation.

The Heidelberg Appendicitis Score Predicts Perforated Appendicitis in Children.

In the future, surgical management of pediatric appendicitis might become limited to nonperforating appendicitis. Thus, it becomes increasingly important to differentiate advanced from simple appendicitis and to predict perforated appendicitis among a group of children with right-sided abdominal pain, which was the aim of this study. An institutionally approved, single-center retrospective analysis of all patients with appendectomy from January 2009 to December 2010 was conducted. All diagnostic aspects were evaluated to identify predictors and differentiators of perforated appendicitis. In 2 years, 157 children suffered from appendicitis. Perforation occurred in 47 (29.9%) of the patients. C-reactive protein (CRP) levels higher than 20 mg/dL ( P = .037) and free abdominal fluid on ultrasonography ( P = .031) are the most important features to differentiate perforated from simple appendicitis. Moreover, all children with perforation had a positive Heidelberg Appendicitis Score (HAS). A negative HAS excludes perforation in all cases (negative predictive value = 100%). Perforated appendicitis can be ruled out by the HAS. In a cohort with right-sided abdominal pain, perforation should be considered in children with high CRP levels and free fluids or abscess formation on ultrasound.

Experimental Studies on Wave Interactions of Partially Perforated Wall under Obliquely Incident Waves

This study presents wave height distribution in terms of stem wave evolution phenomena on partially perforated wall structures through three-dimensional laboratory experiments. The plain and partially perforated walls were tested to understand their effects on the stem wave evolution under the monochromatic and random wave cases with the various wave conditions, incident angle (from 10 to 40 degrees), and configurations of front and side walls. The partially perforated wall reduced the relative wave heights more effectively compared to the plain wall structure. Partially perforated walls with side walls showed a better performance in terms of wave height reduction compared to the structure without the side wall. Moreover, the relative wave heights along the wall were relatively small when the relative chamber width is large, within the range of the chamber width in this study. The wave spectra showed a frequency dependency of the wave energy dissipation. In most cases, the existence of side wall is a more important factor than the porosity of the front wall in terms of the wave height reduction even if the partially perforated wall was still effective compared to the plain wall.

Various procedure-related adverse events related to colonoscopic treatment have been reported. Previous studies on the complications of colonoscopic treatment have focused primarily on perforation or bleeding. Coagulation syndrome (CS), which is synonymous with transmural burn syndrome following endoscopic treatment, is another typical adverse event. CS is the result of electrocoagulation injury to the bowel wall that induces a transmural burn and localized peritonitis resulting in serosal inflammation. CS occurs after polypectomy, endoscopic mucosal resection (EMR), and even endoscopic submucosal dissection (ESD). The occurrence of CS after polypectomy or EMR varies according previous reports; most report an occurrence rate around 1%. However, artificial ulcers after ESD are largely theoretical, and CS following ESD was reported in about 9% of cases, which is higher than that for CS after polypectomy or EMR. Most cases of post-polypectomy syndrome (PPS) have an excellent prognosis, and they are managed conservatively with medical therapy. PPS rarely develops into delayed perforation. Delayed perforation is a severe adverse event that often requires emergency surgery. Since few studies have reported on CS and delayed perforation associated with CS, we focused on CS after colonoscopic treatments in this review. Clinicians should consider delayed perforation in CS patients. PMID:26380051

Vinorelbine induced perforation of a metastatic gastric lesion.

Breast carcinoma metastasis to the gastrointestinal tract is rare and more frequently associated with lobular than ductal carcinoma (Borst and Ingold, Surg 114(4):637-641 [1]). The purpose of this article is to present a case based review of a unique gastrointestinal metastasis and literature review. A 46 year old lady with metastatic invasive ductal breast cancer was admitted to A&E with sudden onset of epigastric and left shoulder pain. She completed the first cycle of capecitabine/vinorelbine 1 week previously. Clinical examination revealed a tender epigastrium with rigidity in the upper abdomen. Free air under the diaphragm and a positive Rigler's sign was radiologically identified. A laparoscopy demonstrated a fibrinous exudate in the left upper quadrant consistent with a walled off lesser curvature gastric perforation. A subsequent oesophagogastroduodenoscopy (OGD) demonstrated a healed gastric ulcer of benign appearance; however the pathology confirmed metastatic breast carcinoma. Literature review confirmed no previously reported cases of vinorelbine induced gastric perforation. Four cases of metastatic breast cancer with gastric metastasis presenting with perforation were identified; three of these cases (Fra et al., Presse Med 25(26):1215 (1996) [2], Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91-92 (2004) [3], Ghosn et al., Bull Cancer 78(11):1071-1073 (1991) [4]), were in the French medical literature, including one male patient (Fra et al., Presse Med 25(26):1215 (1996) [2]) and at least one ductal breast carcinoma (Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91-92 (2004) [3]). The fourth case (van Geel et al., Ned Tijdschr Geneeskd 144(37):1761-1763 (2000) [5]), was in the Dutch medical literature and a lobular breast carcinoma. This case represents a rare complication of breast cancer chemotherapy, the subsequent significant benefit the patient received from treatment is consistent with the chemosensitivity to therapy that also resulted in gastric perforation. Five years after gastric perforation she resumed palliative chemotherapy after progression on sequential hormonal therapies.

An elderly male presented for emergent repair of a ruptured abdominal aortic aneurysm. For anticipated volume resuscitation, vasopressor administration, and hemodynamic monitoring, a large-bore central venous catheter was placed in the left internal jugular vein under ultrasound guidance before surgical incision. Initially, there were no readily apparent signs of venous perforation. However, a massive left hemothorax developed because of perforation of the brachiocephalic vein and violation of the pleural space. This case report discusses both prevention and management of such a complication.

Complex defects present structural and functional challenges to reconstructive surgeons. When compared to multiple free flaps or staged reconstruction, the use of chimeric flaps to reconstruct such defects have many advantages such as reduced number of operative procedures and donor site morbidity as well as preservation of recipient vessels. With increased popularity of perforator flaps, chimeric flaps' harvest and design has benefited from 'perforator concept' towards more versatile and better reconstruction solutions. This article discusses perforator based chimeric flaps and presents a practice based classification system that incorporates the perforator flap concept into "Perforator Chimerism". The authors analyzed a variety of chimeric patterns used in 31 consecutive cases to present illustrative case series and their new classification system. Accordingly, chimeric flaps are classified into four types. Type I: Classical Chimerism, Type II: Anastomotic Chimerism, Type III: Perforator Chimerism and Type IV Mixed Chimerism. Types I on specific source vessel anatomy whilst Type II requires microvascular anastomosis to create the chimeric reconstructive solution. Type III chimeric flaps utilizes the perforator concept to raise two components of tissues without microvascular anastomosis between them. Type IV chimeric flaps are mixed type flaps comprising any combination of Types I to III. Incorporation of the perforator concept in planning and designing chimeric flaps has allowed safe, effective and aesthetically superior reconstruction of complex defects. The new classification system aids reconstructive surgeons and trainees to understand chimeric flaps design, facilitating effective incorporation of this important reconstructive technique into the armamentarium of the reconstruction toolbox.

Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Recently, perforator propeller flaps have been used for resurfacing the upper extremity. The anterior interosseus artery perforator flap is an uncommonly used and described flap. This study was divided into anatomical study and clinical application in a IV level of evidence. In the anatomical study, five upper extremities were studied. Clinically, 12 patients underwent reconstruction using the anterior interosseus artery perforator flap. Flaps were performed by a single surgeon. A retrospective review of these cases from November 2008 to May 2014 is presented. The anterior interosseus artery perforator was identified in four out of five cadaver limbs. The septocutaneous perforator was in the fifth extensor compartment around 4 cm proximal to the wrist joint. Of the twelve flaps, there was complete necrosis in one flap, and partial necrosis in one flap. The patient with complete necrosis underwent skin grafting at a later date. The wound healed secondarily in case of partial flap necrosis. Anterior interosseus artery perforator flap must be considered as an important reconstructive option in the armamentarium of the plastic surgeon, while managing hand and wrist defects.

Endoscopic closure of septal perforations.

PubMed

Alobid, Isam

The management of septal perforations is a challenge for the surgeon. A wide variety of surgical techniques have been described, with different approaches. There is no scientific evidence to support a particular approach. The objective of this review is to present a practical guide on the technique of choice for each case of septal perforation. Inspection of the nasal mucosa, the size of the perforation, the location and especially the osteo-cartilaginous support, are the pillars of a successful surgery. For the sliding or rotating flaps of the mucosa of the septum it is essential to know in advance if the elevation of the mucopericondrio or mucoperiosteo of the septum is possible, otherwise the use of these flaps would not be indicated. The flaps of the lateral wall or nasal floor are the alternative. The pericranial flap may be indicated in total or near total perforations. The remnant of the nasal septum and status of osteo-cartilaginous support are the determining factors in the management of septal perforations. Each case should be evaluated individually and the approach chosen according to the size and location of the perforation, mucosal quality, personal history, previous surgery and the experience of the surgeon.

One of the main steps in perforator flap surgery is to identify the dominant perforator. Using multidetector row computed tomography (MDCT) for the preoperative planning of deep inferior epigastric artery perforator (DIEAP) flap surgery, we identified a perforator with a large caliber, an excellent location in the middle abdominal region, and a totally extramuscular trajectory in a significant number of patients. We describe the frequency of this perforator and determine its characteristics. We conducted a retrospective study of 482 patients who underwent 526 DIEAP flaps for breast reconstruction from October 2003 to October 2011. Mean age at surgery was 51.3 years old. A preoperative MDCT of abdominal vascularization was performed in all patients. MDCT identified a dominant perforator with a paramuscular course in 12.4% of abdominal walls. In all cases, it was located in the midline and emerged directly from the deep inferior epigastric system. Its mean caliber was 1.9 mm. The flap was harvested based on this perforator in all these patients, and mean harvest time was 51 minutes. The characteristics of this perforator made dissection easier and reduced morbidity at the donor site. There were no flap losses and the only complications were minor. We located a paramuscular perforator in 12.4% of patients undergoing breast reconstruction with abdominal perforator flaps. Its morphological features and extramuscular course make it the perforator of choice in DIEAP flap surgery.

Duodenal ulcer is an uncommon condition in children, that is why it is not usually considered as the differential diagnosis unless it presents with complications including perforation and haemorrhage. Moreover, duodenal ulcer perforation is an uncommon entity in paediatric age group. Early diagnosis and treatment is crucial in order to improve survival. A three-day-old male neonate was admitted to our hospital because of abdominal distension. The neonate was lethargic. He underwent laparotomy. There was a perforated ulcer, 5×5mm in size, on the anterior aspect of the first part of the duodenum. The perforated ulcer was closed with a single layer. Six-month follow-up revealed no abnormality.

The analysis of 100 cases of colon perforation during colposcopic examinations highly demonstrates such a statement. The perforation risk during colposcopies is generally of the order of 0.2% for a diagnosis coloscopy. According to the statistic data used, it can reach 0.5 to 3% in therapy coloscopy. This is a risk inherent to the technique used. It is thus required to analyse the causes and take the appropriate measures to reduce it to a minimum. Mortality due to such a complication remains high (14%), i.e about 0.015 to 0.1% (#2/10000) of all colposcopies. In 11% of the patients, serious sequelae are to be observed. This demonstrates the significance of the medico-legal problem set by these perforations during colposcopies. The whole personnel responsibility can be involved: colposcopist, surgeon, anesthetist and hospital unit.

Interleukin-12 (IL-12) is a cytokine which is secreted by activated phagocytes and dendritic cells and promotes cell-mediated immunity to intracellular pathogens, by inducing type 1 helper T cell (TH1) responses and interferon- γ (IFN- γ) production. Defects in the IL-12 may cause selective susceptibility to intracellular pathogens, such as mycobacteria. We herein report on a 13-year-old girl with defective mitogen-induced IL-12 production, who developed intestinal tuberculosis with wide dissemination involving the lung and urinary tract. She improved gradually, but developed terminal ileal perforation approximately 6.1 months following initiation of anti-tuberculous treatment. The paradoxical response phenomenon was suspected. The girl subsequently underwent surgical resection of the affected bowel segment with a temporary double barrel stoma, and ileocolonic anastomosis was performed after the completion of the anti-tuberculous therapy. The patient remained well, with no evidence of recurrent tuberculosis in the past 5 years. This case illustrates the possibility of underlying primary immunodeficiency in a patient with disseminated tuberculosis; delayed tuberculous intestinal perforation can develop during chemotherapy for tuberculosis.

Teven, Chad M; Mhlaba, Julie; O'Connor, Annemarie; Gottlieb, Lawrence J

The majority of surgical burn care involves the use of skin grafts. However, there are cases when flaps are required or provide superior outcomes both in the acute setting and for postburn reconstruction. Rarely discussed in the context of burn care, the perforator-based propeller flap is an important option to consider. We describe our experience with perforator-based propeller flaps in the acute and reconstructive phases of burn care. We reviewed demographics, indications, operative details, and outcomes for patients whose burn care included the use of a perforator-based propeller flap at our institution from May 2007 to April 2015. Details of the surgical technique and individual cases are also discussed. Twenty-one perforator-based propeller flaps were used in the care of 17 burn patients. Six flaps (29%) were used in the acute phase for coverage of exposed joints, tendons, cartilage, and bone; coverage of open wounds; and preservation of range of motion (ROM) by minimizing scar contracture. Fifteen flaps (71%) were used for reconstruction of postburn deformities including coverage of chronic wounds, for coverage after scar contracture release, and to improve ROM. The majority of flaps (94% at follow-up) exhibited stable soft tissue coverage and good or improved ROM of adjacent joints. Three cases of partial flap loss and one case of total flap loss occurred. Perforator-based propeller flaps provide reliable vascularized soft tissue for coverage of vital structures and wounds, contracture release, and preservation of ROM across joints. Despite a relatively significant risk of minor complications particularly in the coverage of chronic wounds, our study supports their utility in both the acute and reconstructive phases of burn care.

Perforated duodenal ulcer presenting with a subphrenic abscess revealed by plain abdominal X-ray films and confirmed by multi-detector computed tomography: a case report

PubMed Central

2013-01-01

Introduction Peptic ulcer disease is still the major cause of gastrointestinal perforation despite major improvements in both diagnostic and therapeutic strategies. While the diagnosis of a perforated ulcer is straightforward in typical cases, its clinical onset may be subtle because of comorbidities and/or concurrent therapies. Case presentation We report the case of a 53-year-old Caucasian man with a history of chronic myeloid leukemia on maintenance therapy (100mg/day) with imatinib who was found to have a subphrenic abscess resulting from a perforated duodenal ulcer that had been clinically overlooked. Our patient was febrile (38.5°C) with abdominal tenderness and hypoactive bowel sounds. On the abdominal plain X-ray films, a right subphrenic abscess could be seen. On contrast-enhanced multi-detector computed tomography, a huge air-fluid collection extending from the subphrenic to the subhepatic anterior space was observed. After oral administration of 500cm3 of 3 percent diluted diatrizoate meglumine, an extraluminal leakage of the water-soluble iodinated contrast media could then be appreciated as a result of a perforated duodenal ulcer. During surgery, the abscess was drained and extensive adhesiolysis had to be performed to expose the duodenal bulb where the ulcer was first identified by methylene blue administration and then sutured. Conclusions While subphrenic abscesses are well known complications of perforated gastric or duodenal ulcers, they have nowadays become rare thanks to advances in both diagnostic and therapeutic strategies for peptic ulcer disease. However, when peptic ulcer disease is not clinically suspected, the contribution of imaging may be substantial. PMID:24215711

To study the microanatomy of the perforating arteries in the superior space of the internal carotid artery visualized through a pterional approach. Twelve (24 sides) perfused cadaver heads were dissected via the pterional approach, and the perforating arteries in the superior space of the internal carotid artery were studied under microscope. The diameter, course and distribution in the anterior perforated substance of the perforating arteries were recorded. All the perforating arteries exposed lied on the side of the brain tissue. The carotid bifurcation on 8 sides had perforating arteries, and 11 sides showed medial lenticulostriate artery of the middle cerebral arteries, with short course and overlapped with another perforating arteries upon entry into the anterior perforated substance. On 4 sides, the medial lenticulostriate artery coincided with the perforating arteries in A1. All 24 sides showed middle lenticulostriate artery and lateral lenticulostriate artery of the middle cerebral arteries. Most of the lenticulostriate arteries originated from the anterior segment of the bifurcation of the middle cerebral arteries. The earlier bifurcation occurred in M1 of the middle cerebral arteries, the more perforating arteries originated. On 22 sides, the anterior cerebral arteries had perforating arteries with many branches, and fewer perforating arteries in a main artery were associated with greater diameter of them. The superior space of the internal carotid artery allows a space for operation, and in some cases, part of the medial leticulostriate arteries and A1 perforating arteries can be severed to obtain larger space for the operation.

Acute massive gastric dilatation (AMGD) is a rare distinctive condition but associates with high morbidity and mortality. Though usually seen in patients with eating disorders, many aetiologies of AMGD have been described. The distension has been reported to cause gastric necrosis with or without perforation, usually within 1-2 days of an inciting event of AMGD.We report the case of a 58-year-old male who presented with gastric perforation associated with AMGD 11 days after surgical relief of a proximal small bowel obstruction. The AMGD arose from a closed loop obstruction between a tumour at the gastro-oesophageal junction and a small bowel obstruction as a result of volvulus around a jejunal feeding tube.To our knowledge, this is the first case of a closed loop obstruction of this aetiology reported in the literature, and the presentation of this patient's AMGD was notable for the delayed onset of gastric necrosis. The patient underwent an exploratory laparotomy and a partial gastrectomy to excise a portion of his perforated stomach. Surgeons should be aware of the possibility of delayed ischaemic gastric perforation in cases of AMGD. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Abdominal gas gangrene caused by clostridia species is rare and usually associated with organ perforation, immune suppression, or advanced malignoma. A 61-year-old man was admitted with severe back pain 1 day after uncomplicated colonoscopic polypectomy. With the exception of preexisting minor depression, the patient had been previously in excellent health. The computed tomography scan showed retroperitoneal emphysema in the left psoas muscle. During exploratory laparotomy, a spreading retroperitoneal phlegmon with pneumoretroperitoneum and a secondary peritonitis were found. A macroscopic perforation of the gut, particularly at the polypectomy sites was excluded. After the operation, the patient evolved in a septic shock condition and had pulmonary failure. Before hyperbaric oxygen therapy could be employed, the patient died. The autopsy showed a massive gas gangrene of the retroperitoneum caused by Clostridium perfringens, but no macroscopic bowel perforation was detected. This is the first report of a case of gas gangrene after uncomplicated polypectomy without macroscopic perforation in an otherwise healthy individual. A microperforation due to mucosal defect after polypectomy was most likely the entry point for the bacteria. We conclude that clostridial myonecrosis should be considered in unclear abdominal infections, even if the patient's history is not typical as in the present case.

Acute appendicitis is one of the most common causes of acute abdominal pain. Accurate diagnosis is often hindered due to various presentations that differ from the typical signs of appendicitis, especially the position of the appendix. A delay in diagnosis or treatment may result in increased risks of complications, such as perforation, which is associated with increased morbidity and mortality rates. Necrotizing fasciitis caused by perforated appendicitis is extremely rare. We herein report a case of 50-year-old man presenting with an appendiceal abscess in local hospital. After ten days of conservative treatment with intravenous antibiotics, the patient complained about pain and swelling of the right lower limb and computed tomography (CT) demonstrated a perforated appendix and gas and fluid collection extending from his retroperitoneal cavity to the subcutaneous layer of his right loin and right lower limb. He was transferred to our hospital and was diagnosed with necrotizing fasciitis caused by perforated appendicitis. Emergency surgery including surgical debridement and appendectomy was performed. However, the patient died of severe sepsis and multiple organ failure two days after the operation. This case represents an unusual complication of a common disease and we should bear in mind that retroperitoneal inflammation and/or abscesses may cause necrotizing fasciitis through lumbar triangles.

We present a case of reactivated herpes zoster keratouveitis of 6 years duration with corneal perforation requiring penetrating keratoplasty shortly after inoculation with herpes zoster vaccine (Zostavax, Merck, Quebec, Canada). Retrospective case report. A 67-year-old woman with a 5-year history of recurrent unilateral herpes zoster keratouveitis in her right eye presented with another recurrence 2 weeks after Zostavax vaccination. Three months later, she developed descemetocele and 2 months afterward, corneal perforation, which was managed by penetrating keratoplasty. Immunohistopathological examination disclosed positive staining for varicella zoster virus in most of the keratocytes adjacent to the descemetocele and perforation, most vividly in the deeper two-thirds of the stroma where the keratocytes were most dense, but not in corneal epithelium or endothelium. Electron microscopic examination showed universally severely degenerated corneal keratocytes in the corneal stroma adjacent to the perforation with variable numbers of herpes virus capsids present in half of these cells. Only a rare normal-appearing keratocyte was identified in the more peripheral corneal stroma. We present a case of reactivation of herpes keratouveitis shortly after vaccination with Zostavax in a patient with previous herpes zoster ophthalmicus. We demonstrate, for the first time, ultrastructural evidence consistent with inactive virus capsids in diffusely degenerated keratocytes in the extracted corneal tissue.

Calf Perforator Flaps: A Freestyle Solution for Oral Cavity Reconstruction.

PubMed

Molina, Alexandra R; Citron, Isabelle; Chinaka, Fungayi; Cascarini, Luke; Townley, William A

2017-02-01

Reconstruction of oral cavity defects requires a thin, pliable flap for optimal functional results. Traditional flap choices are imperfect: the anterolateral thigh flap is excessively thick, whereas the radial forearm flap has a poor donor site. The authors therefore favor calf perforator flaps such as the medial sural artery perforator flap to provide thin tissue with an acceptable donor site. This two-part study aims to demonstrate their suitability for intraoral reconstruction. In the radiologic part of the study, the authors compared thigh and calf tissue thickness by examining lower limb computed tomographic scans of 100 legs. For their clinical study, they collected data prospectively on 20 cases of oral cavity reconstruction using calf perforator flaps. The mean thickness of the calf tissue envelope was significantly less than that of the thigh (8.4 mm compared with 17 mm) based on computed tomographic analysis. In the clinical study, a medial sural artery perforator was used in the majority of cases (17 of 20). The mean pedicle length was 10.2 cm and the mean time to raise a flap was 85 minutes. There were no flap losses. One patient was returned to the operating room for management of late hematoma and wound dehiscence. Calf perforator flaps provide ideal tissue for intraoral reconstruction and are significantly thinner than anterolateral thigh flaps. In addition to medial sural artery perforator flaps, the authors raised both sural and soleal artery perforator flaps in this series. Opportunistic use of the calf donor site allows the harvest of thin tissue with minimal donor-site morbidity. Therapeutic, IV.

To explore the effectiveness of propeller facial artery perforator flap to repair the defect after resection of skin malignant tumor at upper lip. Between July 2012 and January 2017, 17 cases with skin malignant tumor at upper lip underwent tumor resection and the remained defect was repaired with propeller facial artery perforator flap. Among the 17 patients, 3 were male and 14 were female, with an average age of 57 years (range, 35-82 years). There were 5 cases of squamous cell carcinoma and 12 cases of basal cell carcinoma. The disease duration ranged from 4 months to 11 years with an average of 20 months. The tumor size ranged from 1.4 cm×0.3 cm to 3.1 cm×1.4 cm. The extended resection of the tumor tissue was performed according to the characters of tumor. According to the location, size, and shape of the defect and the position of facial artery perforator explored with Doppler ultrasonography, the propeller facial artery perforator flap was designed to repair the defect and partial donor site. The flap size ranged from 5 cm×2 cm to 7 cm×3 cm. The length of the perforator pedicle was 0.5-1.0 cm with an average of 0.8 cm. The defect at donor site was directly closed. Cyanosis occurred in 3 cases of the distal flap after operation, then healing after symptomatic treatment. The remaining flaps survived successfully and the wound healed by first intention. Primary healing was obtained in the donor site. All the patients were followed up 6-36 months with an average of 18 months. The shape of the patient's upper lip was good and the scar on the donor site was unconspicuous. There was no lip deformity, ala nasi deflection, facial tension, entilation dysfunction, or recurrence of tumor during follow-up. At last follow-up, the results of self-evaluation were very satisfactory in 13 cases and satisfactory in 4 cases. Based on multiple advantages of good blood supply, large rotation range, aesthetic outcome, and slight injury of the donor site, propeller facial artery perforator flap is not only an optimal choice for repairing upper lip defect after resection of skin malignant tumors, but also can achieve good functional and cosmetic effectiveness.

To investigate the results of resurfacing completely degloved digits using bilobed innervated radial artery superficial palmar branch (RASPB) perforator flap in a spiral fashion. A detailed anatomic study on 30 adult fresh frozen cadavers preinjected with silicone rubber compound to demarcate arterial anatomy documented locations, numbers, and diameters of arteries and skin perforators with surrounding nerves. The flap-raising procedure was performed using four fresh cadaver specimen. We reviewed the reconstruction of 12 digits by using a bilobed spiraled innervated RASPB free perforator flap after non-replantable degloving injury. Two skin paddles were marked out using standard points of reference. At least two separate cutaneous perforator vessels were identified using a hand-held Doppler and were dissected back to the RASPB in retrograde fashion. The skin paddles were then divided between the two cutaneous perforators to provide two separate paddles with a common vascular supply. The skin paddles were stacked in a spiral fashion on the flap inset, effectively increasing the width of the flap to cover the totally degloved finger while still allowing closure of the primary donor-site. The RASPB was present within the flap in all cadavers. The direct perforator and the musculocutaneous perforator were available in 93.33 and 76.67 %, respectively, with neither of them in 6.67 % of the cases. The constantly present two perforators allowed the design of a new bilobed spiraled innervated radial artery superficial palmar branch perforator flap. We used the proposed flap to reconstruct completely degloved digits in 12 patients (mean age 28.6 years; range 17-35 years). With our proposed flap, no flap failure or re-exploration occurred and the donor site was closed primarily in all cases. All the flaps survived uneventfully. Total active motion ranged from 92° to 140° and 111° to 155° in the cases with and without metacarpophalangeal joint involvement, respectively. The static 2 point discrimination test varied from 6 to 11 mm. All the patients were satisfied with the overall results. The bilobed flap is large enough to cover totally degloved finger defects and contain direct skin perforators, provides a bespoke cover for complex soft tissue defects of completely degloved digits while also improving morbidity and cosmesis of the donor site.

The presence of a urologic injury must be considered in all patients with pelvic fracture. Uroradiographic evaluation starting with retrograde urethrography is indicated in all male patients with concomitant gross hematuria, bloody urethral discharge, scrotal or perineal ecchymosis, a nonpalpable prostate on rectal examination, or an inability to urinate. If the urethra is normal, a catheter may be passed, and in the presence of gross hematuria, a cystogram must be performed. Female patients rarely suffer urethral lacerations. The urethra is examined, and a Foley catheter may be passed without a urethrogram. The immediate management of associated urologic injuries continues to evolve and evoke controversy. Selected cases of extraperitoneal bladder perforation may be safely managed solely by catheter drainage. Intraperitoneal perforations require surgical exploration and repair. Urethral disruption (partial or complete) may be safely managed by primary cystostomy drainage with management of potential complications (stricture, impotence, incontinence) in 4 to 6 months.

Application of Layered Perforation Profile Control Technique to Low Permeable Reservoir

it is difficult to satisfy the demand of profile control of complex well section and multi-layer reservoir by adopting the conventional profile control technology, therefore, a research is conducted on adjusting the injection production profile with layered perforating parameters optimization. i.e. in the case of coproduction for multi-layer, water absorption of each layer is adjusted by adjusting the perforating parameters, thus to balance the injection production profile of the whole well section, and ultimately enhance the oil displacement efficiency of water flooding. By applying the relationship between oil-water phase percolation theory/perforating damage and capacity, a mathematic model of adjusting the injection production profile with layered perforating parameters optimization, besides, perforating parameters optimization software is programmed. Different types of optimization design work are carried out according to different geological conditions and construction purposes by using the perforating optimization design software; furthermore, an application test is done for low permeable reservoir, and the water injection profile tends to be balanced significantly after perforation with optimized parameters, thereby getting a good application effect on site.

Summary: We present our experience of bilateral total breast reconstruction using a double-sided extended thoracodorsal artery perforator propeller flap in a case series of 10 patients. Reconstruction was successfully achieved in all cases with few complications. The median time for surgery was 275 minutes (200–330), and the average implant size used was 350 cm3 (195–650). We demonstrate how the extended thoracodorsal artery perforator propeller flap allows for a swift and reliable direct to implant bilateral total breast reconstruction in a simple setting and is a valuable adjunct to our armamentarium of techniques for single-stage bilateral breast reconstruction.

Fetal bowel intrauterine perforation causes sterile inflammation of the peritoneum, known as meconium peritonitis. In some cases the perforation closes spontaneously, thus forming a meconium pseudocyst between the intestinal loops and the omentum. Meconium peritonitis, complicated by pseudocyst formation, should always be considered when a fetal abdominal mass with diverse echogenicity and hyperechogenic calcifications is observed on prenatal ultrasound. Usually, this is associated with ascites and/or polyhydramnios. The differential diagnosis necessitates exclusion of all other fetal abdominal tumors. We present a case report of meconium pseudocyst diagnosed prenatally at 32 weeks of gestation which was successfully treated by surgery after birth.

Propeller flap reconstruction of abdominal defects: review of the literature and case report.

Scaglioni, Mario F; Giuseppe, Alberto Di; Chang, Edward I

2015-01-01

The abdominal wall is perfused anteriorly by the superior and deep epigastric vessels with a smaller contribution from the superficial system. The lateral abdominal wall is perfused predominantly from perforators arising from the intercostal vessels. Reconstruction of soft tissue defects involving the abdomen presents a difficult challenge for reconstructive surgeons. Pedicle perforator propeller flaps can be used to reconstruct defects of the abdomen, and here we present a thorough review of the literature as well as a case illustrating the perforasome propeller flap concept. A patient underwent resection for dermatofibrosarcoma protuberans resulting in a large defect of the epigastric soft tissue. A propeller flap was designed based on a perforator arising from the superior deep epigastric vessels and was rotated 90° into the defect allowing primary closure of the donor site. The patient healed uneventfully and was without recurrent disease 37 months following reconstruction. Perforator propeller flaps can be used successfully in reconstruction of abdominal defects and should be incorporated into the armamentarium of reconstructive microsurgeons already facile with perforator dissections. © 2014 Wiley Periodicals, Inc.

An 85-year-old woman was admitted to our hospital for steroid therapy for relapsing nephrotic syndrome. During hospitalization, she complained of sudden epigastric pain at night. Although there were signs of peritoneal irritation, CT showed a large amount of ascitic fluid, but no free intraperitoneal gas. Gram staining of ascitic fluid obtained by abdominal paracentesis showed Gram-negative rods, which raised a strong suspicion of gastrointestinal perforation and peritonitis. Therefore, emergency surgery was performed. Exploration of the colon showed multiple sigmoid diverticula, one of which was perforated. The patient underwent an emergency Hartmann's procedure. Imaging studies failed to reveal any evidence of gastrointestinal perforation, presenting a diagnostic challenge. However, a physician performed rapid Gram staining of ascitic fluid at night when laboratory technicians were absent, had a strong suspicion of gastrointestinal perforation, and performed emergency surgery. Gram staining is superior in rapidity, and ascitic fluid Gram staining can aid in diagnosis, suggesting that it should be actively performed. We report this case, with a review of the literature on the significance of rapid diagnosis by Gram staining.

The results of the surgical management of 161 cases of ileal perforation due to typhoid fever are presented. Most were seen after an illness of 2-4 weeks, and because of delays in seeking hospital admission, more than half were explored more than 24 hours after their perforation occurred. All patients were prepared for operation with nasogastric suction, intravenous fluids, and antibiotics. At laparotomy, 80% had considerable quantities of pus and small bowel contents in the peritoneal cavity and the remainder had localized abscesses; there were no instances of localization of the perforation. One hundred three of these patients underwent simple closure of their perforations, while 43 underwent small bowel resection, usually because of multiple perforations. Exteriorization or drainage were performed only in patients too sick to tolerate a more appropriate procedure. The overall mortality was 9.9%. The authors believe that typhoid perforations can best be dealt with at operation. Delay in operative intervention adversely affects the survival rate after surgery. Chloramphenicol is used as the drug of choice. PMID:1119873

To explore the feasibility and technical essentials of soft tissue defect reconstruction following malignant tumor removal of limbs using perforator propeller flaps. Between July 2008 and July 2015, 19 patients with malignant limb tumor underwent defect reconstruction following tumor removal using the perforator propeller flaps. There were 13 males and 6 females with an average age of 53.4 years (range, 20-82 years). The disease duration ranged from 1 to 420 months (mean, 82 months). The tumors located at the thigh in 10 cases, at the leg in 2 cases, at the arm in 1 case, at the forearm in 1 case, around the knee in 2 cases, and around the elbow joint in 3 cases. Totally 23 flaps (from 8 cm x 3 cm to 30 cm x 13 cm in size) were used to reconstruct defects (from 4 cm x 4 cm to 24 cm x 16 cm in size). The potential source arteries included the femoral artery (n = 2), profunda femoral artery (n = 3), superficial circumflex iliac artery (n = 1), lateral circumflex femoral artery (n = 6), superior lateral genicular artery (n = 2), peroneal artery (n = 2), anterior tibial artery (n = 1), brachial artery (n = 4), and radial artery (n = 1). The remaining one was a free style perforator flap. Partial distal flap necrosis occurred in 3 cases after surgery with rotation angles of 180, 150, and 100 degrees respectively, which were reconstructed after debridement using a free-style perforator flap in 1 case and using free skin grafting in the other 2 cases. The other 20 flaps survived completely after surgery. Primary healing of incisions was obtained at the donor and recipient sites. There was no severe complication such as infection, hematoma, and total flap failure. All patients were followed up 3 months to 5 years (mean, 19 months). One patient with malignant melanoma around the elbow joint had tumor recurrence, and underwent secondary tumor resection. The appearance, texture, and color of the flaps were similar to those at the recipient site. For patients with malignant tumor of the limb, the perforator propeller flap can be an alternative option for soft tissue defect reconstruction after tumor resection, with the advantages of relatively simple operation and remaining the main vessels.

Duplicated middle cerebral artery

2009-01-01

Duplicated middle cerebral artery (DMCA) is an anomalous vessel arising from the internal carotid artery. The incidence DMCA is relatively law, and an association between this anomaly and cerebral aneurysms has been documented. There is a controversy whether DMCA may have perforating arteries. This is an important fact to consider in aneurysm surgery. We report the case of a 34-year-old black woman who suffered a subarachnoid hemorrhage and the angiography a left DMCA, and an aneurysm in an inferior branch of the main MCA. The DMCA and the MCA had perforating arteries. The aneurysm was clipped without complications. The observation of perforating arteries in our patient confirms that the DMCA may have perforating arteries. This is very important to be considered in cerebral aneurysms surgery. Moreover, the DMCA may potentially serve as a collateral blood supply to the MCA territory in cases of MCA occlusion. PMID:22140405

We report a case of eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss syndrome) complicated by perforation of the small intestine and necrotizing cholecystitis. A 69-year-old man with a history of bronchial asthma was admitted with mononeuritis multiplex. The laboratory findings included remarkable eosinophilia. He was treated with corticosteroids and his laboratory indices showed improvement; however, his functional deficits remained. His neuropathy gradually improved after the addition of intravenous immunoglobulin (IVIG). He was subsequently treated with oral prednisolone (40 mg/day) as maintenance therapy. Within a month after finishing IVIG, he developed perforation of the small intestine and necrotizing cholecystitis. Intestinal perforation has often been reported as a gastrointestinal complication of EGPA. In contrast, cholecystitis is a rare complication. We report this case because the manifestation of more than one complication is extremely rare. Gastrointestinal symptoms may be a complication of EGPA itself and/or immunosuppressive treatment.

Nonspecific small bowel ulcers are rare and there have been limited reports. We applied laparoscopic surgery successfully for the perforation caused by this disease of jejunum. A 70-year-old man visited to our hospital with complaint of abdominal pain and fever. He was diagnosed abdominal peritonitis with findings of intraperitoneal gas and fluid. Emergency laparoscopic surgery was performed. A perforation 5mm in diameter was recognized in jejunum opposite side of mesentery. Partial resection of jejunum with end-to-end anastomosis and peritoneal lavage were performed. Pathologically, an ulcer was recognized around the blowout perforation without specific inflammation. He was discharged uneventfully 12days after surgery. Laparoscopic surgery has diagnostic and therapeutic advantages because of its lower invasion with a good operation view, and in case of the small bowel, it is easy to shift extra-corporeal maneuver.

A perforated peptic ulcer in a child is a rare entity. Severe abdominal pain in an ill-appearing child with a rigid abdomen and possibly with signs of shock is the typical presenting feature of this life-threatening complication of peptic ulcer disease. We present a case of a 14.5-year-old adolescent girl who developed abdominal and shoulder pain that resolved after 1 day. She was then completely well for 2 days until the abdominal and shoulder pain recurred. On examination, she appeared well, but in pain. A chest radiograph revealed a large pneumoperitoneum. She underwent emergent laparoscopic omental patch repair of a perforated ulcer on the anterior wall of her stomach. Result of a urea breath test to detect Helicobacter pylori was negative. The differential diagnosis of pneumoperitoneum in children is discussed, as are childhood perforated peptic ulcer in general, and the unique clinical features present in this case in particular.

Brain hypothermic therapy (BHT) is becoming a frequently used standard of care for perinatal asphyxia. Although cardiovascular side effects, coagulation disorders, renal impairment, electrolyte abnormalities, impaired liver function, opportunistic infections, and skin lesions are well-known adverse effects of BHT in newborns, little information is available on the clinical features of intestinal perforation-related BHT. We herein report a case of therapeutic brain cooling for perinatal asphyxia complicated by localized intestinal perforation. In practice, the neonatologist should be aware that intestinal perforation in an infant with perinatal asphyxia is possible, particularly following BHT.

Since perforated peptic ulcer is uncommon in children proton pump inhibitor prophylaxis is not routinely recommended when children are treated with high dose steroids. We describe a case of perforated ulcer in a six-year-old patient with nephrotic syndrome treated with high dose prednisolone. Initially, ulcer was not suspected due to uncharacteristic symptoms. The child developed peritoneal signs and surgery revealed a perforated peptic ulcer in the stomach. We recommend treatment with proton pump inhibitors if children, who are treated with high dose steroids develop abdominal symptoms, which can be caused by an ulcus.

Securing transvenous left ventricular (LV) pacing leads without an active fixation mechanism in proximal coronary vein (CV) segments is usually challenging and frequently impossible. We investigated how active fixation leads can be safely implanted in this location, how to avoid perforating the free wall of the CV, and how to recognize and respond to perforations. In five patients with no alternative to LV pacing from proximal CV segments, 4 Fr SelectSecure (Medtronic, Minneapolis, MN, USA) leads, which have a fixed helix, were implanted through a modified 6 Fr guide catheter with a pre-shaped tip (Launcher, Medtronic). Active fixation leads were successfully implanted in proximal CVs in five patients. There were no complications. Acute and chronic pacing thresholds were comparable to those of conventional CV leads. The pre-shaped guide catheter tip remains in close proximity to the myocardial aspect of the CV, directing the lead helix toward a safe implantation site. If only proximal CV pacing sites are available, 4 Fr SelectSecure leads can be safely implanted through a modified Launcher guide catheter, avoiding more invasive implantation techniques. Other than venous stenting or implantation of leads with retractable tines, SelectSecure leads are expected to remain extractable.

BACKGROUND Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Recently, perforator propeller flaps have been used for resurfacing the upper extremity. The anterior interosseus artery perforator flap is an uncommonly used and described flap. METHODS This study was divided into anatomical study and clinical application in a IV level of evidence. In the anatomical study, five upper extremities were studied. Clinically, 12 patients underwent reconstruction using the anterior interosseus artery perforator flap. Flaps were performed by a single surgeon. A retrospective review of these cases from November 2008 to May 2014 is presented. RESULTS The anterior interosseus artery perforator was identified in four out of five cadaver limbs. The septocutaneous perforator was in the fifth extensor compartment around 4 cm proximal to the wrist joint. Of the twelve flaps, there was complete necrosis in one flap, and partial necrosis in one flap. The patient with complete necrosis underwent skin grafting at a later date. The wound healed secondarily in case of partial flap necrosis. CONCLUSION Anterior interosseus artery perforator flap must be considered as an important reconstructive option in the armamentarium of the plastic surgeon, while managing hand and wrist defects.

Nephrostomy tube insertion and/or a ureteral stent placement is advised when pelvi-calyceal perforations are encountered during percutaneous nephrolithotomy (PNL) nevertheless totally tubeless PNL is a possible exit strategy in percutaneous renal surgery therefore case series on the short term clinical outcomes of noninvasive management of iatrogenic pelvicalyceal perforations encountered during PNL is presented. During retrospective analysis of 1271 PNL procedures, 25 incidents of accidental ureteral catheter/ jj stent dislodgement during first 24 post-operative hours were identified in patient who had pelvi calyceal perforations and had no nephrostomy tube (tubeless). Thirteen patients could not be re-stented nor a nephrostomytube could have been placed for them mainly due to patient refusal or comorbid conditions. The main outcome was rate of successful noninvasive management. Eighteen Patients bearing mucosal tears (grade I trauma) or visible peri-pelvic fat (grade II) successfully recovered without need for ureteral stenting or nephrostomy (72.0%). In seven (28.0%) cases of extension of the perforation into the peri-pelvic fat (grade III), either nephrostomy insertion or JJ stenting was needed for resolution of fever and urinoma. The major limitation was the necessity to exclude patients and manage them in the standard fashion according to clinical guidelines. Iatrogenic perforations of the collecting system are quite diverse in terms of severity that result in different natural histories and not all might need urinary diversion via nephrostomy or ureteral stenting.Low grade perforations may be successfully managed in totally tubeless fashion nevertheless further prospective investigations seem warranted.

Perforated Appendicitis After Colonoscopy

PubMed Central

Johnston, Paul

2008-01-01

Background: Acute appendicitis is a rare complication of colonoscopy that has been reported only 12 times in the English-language literature and is usually associated with obstruction of the appendiceal lumen with fecal matter during colonoscopy. None of the previous reports have described findings of perforation of the appendix within 24 hours of colonoscopy. Methods: We present the case report of a patient who underwent urgent laparotomy within 16 hours of colonos-copy for findings of free intraabdominal air and peritonitis from acute perforated appendicitis. Results: Laparoscopy confirmed 2 perforations of the appendix and diffuse peritonitis. Laparotomy was necessary to perform appendectomy, exclude a right colonic injury, and control intraabdominal sepsis. Conclusion: In patients with abdominal pain who have had a recent colonoscopy, a high index of suspicion is necessary for accurate diagnosis of perforated appendicitis. Perforation can occur hours after colonoscopy even when a biopsy is not performed. PMID:18765066

Successful Deep Inferior Epigastric Perforator Flap Harvest despite Preoperative Therapeutic Subcutaneous Heparin Administration into the Abdominal Pannus.

Abdominal free flaps for microsurgical breast reconstruction are most commonly harvested based on the deep inferior epigastric vessels that supply skin and fat via perforators through the rectus muscle and sheath. Intact perforator anatomy and connections are vital for subsequent optimal flap perfusion and avoidance of necrosis, be it partial or total. The intraflap vessels are delicate and easily damaged and it is generally advised that patients should avoid heparin injection into the abdominal pannus preoperatively as this may compromise the vascular perforators through direct needle laceration, pressure from bruising, haematoma formation, or perforator thrombosis secondary to external compression. We report three cases of successful deep inferior epigastric perforator (DIEP) flap harvest despite patients injecting therapeutic doses of low molecular weight heparin into their abdomens for thrombosed central venous lines (portacaths™) used for administering primary chemotherapy in breast cancer.

Perforated Peptic Ulcer (PPU) is extremely rare in pregnancy. We report a case of perforated peptic ulcer in pregnancy during Ramadan fasting. The patient is a 16 years old primigravida who presented with features of peritonitis at 28weeks of gestation while fasting during Ramadan. Ultrasound scan reported a singleton live fetus at 28 weeks gestation. At laparotomy via upper midline incision; a 1 cm roundish perforation located on the duodenum anteriorly was found with about a litre of gastric juice mixed with blood and food particles in the peritoneal cavity. The perforation was close transversely with omental patch (Modified Graham's patch) and peritoneal lavage done with warm saline. She had a preterm delivery of a 1 kg baby 3 days post-operatively by a spontaneous vaginal delivery, but the baby died 3 days later. Perforated Peptic Ulcer(PPU) though rare in pregnancy can occur and fasting can be a risk factor.

2015-06-01

Trunk defects following soft tissue sarcoma resection are usually managed by myocutaneous flaps or free flaps. However, harvesting muscle will cause functional morbidities and some trunk regions lack reliable recipient vessels. The intercostal arteries give off multiple perforators, which distribute widely over the trunk and can supply various pedicle flaps. Our purpose is to use various intercostal artery perforator propeller flaps for trunk oncologic reconstruction. Between November 2013 and July 2014, nine intercostal artery perforator propeller flaps were performed in seven patients to reconstruct the defects following sarcoma resection in different regions of the trunk, including the back, lumbar, chest, and abdomen. Two perforators from intercostal arteries were identified for each flap using Doppler ultrasound probe adjacent to the defect. The perforator with visible pulsation was chosen as the pedicle vessel. An elliptical flap was raised and rotated in a propeller fashion to repair the defects. There were one dorsal intercostal artery perforator flap, four dorsolateral intercostal artery perforator flaps, three lateral intercostal artery perforator flaps, and one anterior intercostal artery perforator flap. The mean skin paddle dimension was 9.38 cm in width (range 6-14 cm) and 21.22 cm in length (range 13-28 cm). All intercostal artery perforator flaps survived completely, except for marginal necrosis in one flap harvested close to the previous flap donor site. The intercostal artery perforator propeller flap provides various and valuable options in our reconstructive armamentarium for trunk oncologic reconstruction. To our knowledge, this is the first case series of using intercostal artery perforator propeller flaps for trunk oncologic reconstruction and clinical application of dorsolateral intercostal artery perforator flaps.

to define the correlation between Mannheim peritonitis index scores and outcomes of different radical and palliative interventions for perforative duodenal ulcer. Treatment of 386 patients with perforative duodenal ulcer is presented. Different surgical techniques were analyzed including stomach resection, various methods of vagotomy with/without drainage, ulcer suturing and ulcerative edges excision with suturing in patients with Mannheim index scores <21, 21-29 and over 29. Clavien-Dindo classification was used to analyze postoperative complications. In 64.3% of cases mortality was caused by peritonitis and peritonitis-associated complications. Surgical features resulted unfavorable outcome only in 35.7% of cases. Severe complications requiring re-operation were predominantly observed after stomach resection. Mannheim peritonitis index is sensitive method allowing prognosis the outcomes in patients with perforative duodenal ulcer. Radical interventions are advisable in Mannheim index scores <21, in other cases palliative surgery for example suturing or edges excision with suturing is preferred. If radical surgery is performed with strict indications (Mannheim index scores <21) volume and type of surgery do not significantly influence on mortality rate.

Background: Environmental determinants of appendicitis are poorly understood. Past work suggests that air pollution may increase the risk of appendicitis. Objectives: We investigated whether ambient ground-level ozone (O3) concentrations were associated with appendicitis and whether these associations varied between perforated and nonperforated appendicitis. Methods: We based this time-stratified case-crossover study on 35,811 patients hospitalized with appendicitis from 2004 to 2008 in 12 Canadian cities. Data from a national network of fixed-site monitors were used to calculate daily maximum O3 concentrations for each city. Conditional logistic regression was used to estimate city-specific odds ratios (ORs) relative to an interquartile range (IQR) increase in O3 adjusted for temperature and relative humidity. A random-effects meta-analysis was used to derive a pooled risk estimate. Stratified analyses were used to estimate associations separately for perforated and nonperforated appendicitis. Results: Overall, a 16-ppb increase in the 7-day cumulative average daily maximum O3 concentration was associated with all appendicitis cases across the 12 cities (pooled OR = 1.07; 95% CI: 1.02, 1.13). The association was stronger among patients presenting with perforated appendicitis for the 7-day average (pooled OR = 1.22; 95% CI: 1.09, 1.36) when compared with the corresponding estimate for nonperforated appendicitis [7-day average (pooled OR = 1.02, 95% CI: 0.95, 1.09)]. Heterogeneity was not statistically significant across cities for either perforated or nonperforated appendicitis (p > 0.20). Conclusions: Higher levels of ambient O3 exposure may increase the risk of perforated appendicitis. PMID:23842601

In open lung surgery the surgical access is encircled by the ribs, which should result in a high glove perforation rate compared with other surgical specialities. Prospectively the surgeon, first and second assistant and the scrub nurse wore double standard latex gloves during 100 thoracotomies. Parameters recorded were: procedure performed, number of perforations, localization of perforation, the seniority of the surgeon, manoeuvre performed at the moment of perforation, immediate cause of perforation, operation time, performance of rib resection during thoracotomy and time of occurrence of the first three perforations. One thousand, six hundred and seventy-three gloves (902 outer, 771 inner) were tested. In 78 operations perforations occurred. There were 150 outer glove perforations (8.9%, 0-8, mean 1.23), 19 inner glove perforations (1.13%, 0-2, mean 0.19). Cutaneous blood exposure was prevented in 78% of all operations and in 87% of all perforations. The perforation rate for the surgeon, the scrub nurse, the first and the second assistant were 61.2, 40.4, 9.7 and 3.1% of all operations, respectively. Rib resection and a duration of more than 2 h resulted in a significant rise of glove perforation rate (P<0.05). The personal experience of the surgeon and the type of operation did not correlate with glove perforation. The immediate cause leading to perforation was named in only 17 cases (13.7%) and comprised contact with bone (seven), a needle stitch (seven) and a production flaw (three). Leaks were localized mostly on the first finger (18%),second finger, (39%) palm and dorsum of the hand (16%). The average occurrence of all first perforations was 38.7 min (range 3-190) after the beginning of surgery, the second after 63.2 min (range 10-195). Fifty-four first perforations (50.5%) were found during the first 30 min of the operation. The reported perforation rate of 78% lies in the highest range of reported perforation rates in different surgical specialities. Double gloving effectively prevented cutaneous blood exposure and thus should become a routine for the thoracic surgeon to prevent transmission of infectious diseases from the patient to the surgeon.

Perforation of one or several intraperitoneal organs during a liposuction procedure is an exceptional but underestimated complication. Knowledge of this complication is essential because of frequent delay in diagnosis and possible dramatic consequences. Nineteen cases were evaluated by experts and are presented in a retrospective analysis. Sixteen women and three men, aged 24 to 72 years, were operated on in France between July of 2001 and January of 2012. Abdominal liposuction (200 to 2400 ml) was performed in combination or not with an abdominoplasty. Uncommon pain and an intestinal obstruction were present in all of the patients. The peritonitis was never frank, replaced frequently by infraclinic peritonitis with septic and/or hypovolemic shock. Diagnosis, performed by abdominal scan between days 1 and 7, revealed intraperitoneal gas or liquid. Perforation, unique or multiple, because of the intraperitoneal passage of the cannula, often in the umbilical region and promoted by the presence of a hernia, involved the following organs: ileum (14 cases), jejunum (two cases), spleen (two cases), transverse colon (one case), cecum (one case), and sigmoid (one case). Death occurred in three cases, between days 2 and 11. Eleven patients had temporary ileostomy or colostomy. Associated complications were abdominal wall cellulitis, necrotizing fasciitis, thrombophlebitis, lung collection, and late subobstructive syndrome. Visceral perforation during liposuction, a severe and sometimes fatal complication with late and difficult diagnosis, is not often reported. Careful technique, particularly if an umbilical approach is used, should avoid this dramatic complication. Therapeutic, IV.

Preoperative Doppler ultrasonography for planning free perforator flaps is widely established to identify preoperatively perforators. The method allows one to localise the penetrating point of the perforator through the abdominal fascia. By this means it is not possible to see the intramuscular course or the position of the perforator in relation to the inferior epigastric artery. Lately the technique of computed tomographic angiography provides an opportunity for visualising the course of perforator vessels in these tissues. This paper summarises our experience with the preoperative CT angiography in our breast centre. Since spring 2009 we have reconstructed the breasts of 44 female patients by using free flaps from the lower abdominal wall. 6 of these were bilateral. In a total number of 50 breast reconstructions we used 23 deep inferior epigastric perforator (DIEP) flaps and 27 muscle-sparing transverse rectus abdominis muscle (TRAM) flaps. In addition to the preoperative ultrasonography, a CT angiography of the lower abdomen was conducted in 29 patients. On average they showed at least 2 perforators on the left as well as right abdominal sides, which could be used as flap vessels based on their signal intensity. Based on their estimated microsurgical dissection complexity, the perforator vessels could be classified into 3 groups: 1) direct perforators of category A with short intramuscular course (39%), 2) perforators with long intramuscular course of category B (50%) and 3) "turn around" perforators of category C, which pass medially around the rectus abdominis (11%). The technique of CT angiography permits a reliable preoperative visualisation of perforators in their entire course and facilitates the selection of the supplying perforator as well as the intraoperative procedure for the surgeon. The suggested classification of perforators into 3 groups simplifies the preoperative assessment of the microsurgical dissection effort. Compared to the commonly used Doppler ultrasonography there are disadvantages like the additional cost factor and the radiation exposure. However, in our experience the more detailed planning increases the safety of flap raising and reduces surgery time, so that we consider CT angiography a positive tool to facilitate free perforator flaps. © Georg Thieme Verlag KG Stuttgart · New York.

Reconstructive surgery for ischial pressure sore defects presents a challenge because of high rates of recurrence. The aim of this study was to describe the use of inferior gluteal artery (IGA) and posterior thigh perforators in management of ischial pressure sores with limited donor sites. Between September 2005 and 2009, 11 patients (9 male, 2 female) with ischial sores were operated by using IGA and posterior thigh perforator flaps. The data of patients included age, sex, cause of paraplegia, flap size, perforator of flap, previous surgeries, recurrences, complications, and postoperative follow-up. Nine IGA and 5 posterior thigh perforator flaps were used. Six patients presented with recurrent lesions, 5 patients were operated for sacral and contralateral ischial pressure sores previously. In 2 patients, IGA and posterior thigh perforator flaps were used in combination. Patients were followed for an average of 34.3 months. In 2 recurrent cases, readvancement of IGA perforator flap and gluteus maximus myocutaneous flap were treatment of choice. Treatment of patients with recurrent lesions or multiple pressure sores is challenging because of limited available flap donor sites. In this study, posterior thigh perforator flaps were preferred in patients in whom the previous donor site was the gluteal region. IGA perforator flaps were the treatment of choice in patients for whom posterior thigh region was previously used. Alternately, preserved perforators of previous conventional myocutaneous flaps enabled us to use these perforators in recurrences.

To perform a retrospective analysis of a series of complicated JID (jejunoileal diverticulitis) cases surgically treated in our service during the period from 2002 to 2015. We treated 12 cases of jejunoileal complicated diverticulosis. 7 women and 5 men. The mean age was 76 years. The clinical presentation in all cases was acute abdominal pain, one with gastrointestinal bleeding. All cases had leukocytosis, neutrophilia and increased acute phase reactants. All patients underwent emergency abdominal CT. In 11 cases, there was consistency between imaging studies and surgical findings. Diverticula were located: jejunum (9) and ileum (3). Urgent exploratory laparotomy was always done and findings were: diverticular perforation with peritonitis (7 cases), diverticular perforation with abscess (4 cases) and in one case an ischemic area with diverticular perforation after embolization. Intestinal resection and anastomosis was performed in all cases. There were no patients, in which the diagnosis of diverticulosis jejunoileal was previously known. Complications were: Clavien I (2), Clavien IIIa (1), Clavien IVb (1), Clavien V (1). Jejunoileal diverticulitis is a rare entity, usually the first sign of onset of diverticular disease not previously known. Abdominal CT is of great diagnostic value. Resection of the affected segment is the treatment of choice.

Resection and primary anastomosis without diverting ileostomy for left colon emergencies: is it a safe procedure?

Large-bowel obstruction and perforation are still frequently occurring entities for the acute care surgeon. In these cases, Hartmann's procedure is the most commonly used surgical technique. However, recent papers demonstrate that colon resection and primary anastomosis (RPA) in the emergency setting is a safe and feasible procedure. We present our series of left colon resection and primary anastomosis procedures from Torrevieja Hospital (Alicante, Spain), performed without bowel irrigation or a diverting ileostomy. Thirty-two RPA procedures were performed in emergency settings for perforation or obstruction, or both, during an 18-month period. The following data were prospectively collected: age, gender, nationality, diagnoses, ASA score, body mass index (BMI), POSSUM score (Physiological and Operative Severity Score for the enumeration of Mortality and morbidity), and the score according to the Hinchey classification. Furthermore, duration of the operation, length of postoperative hospital stay, and mortality and morbidity data were recorded. Sixteen of these patients were diagnosed with acute diverticulitis, 14 patients with neoplasm (of which 9 cases had obstruction, 2 cases had perforation, and 3 cases had both), and foreign body perforation in the remaining 2 cases. The mean hospital stay was 7.8 (range, 4-10) days. The physiological POSSUM score was 24.4 (range, 15-39), and the surgical POSSUM score was 19.8 (range, 16-24). None of the patients died (0% mortality). Seven patients developed some kind of complication (21.9%), all of which were managed conservatively. The results of this study suggest that RPA for left colon obstruction and perforation in emergency settings can be safely performed in certain surgical conditions.

Appendicitis is a common surgical emergency in pediatric patients, and broad-spectrum antibiotic therapy is warranted in their care. A simplified once-daily regimen of ceftriaxone and metronidazole (CTX plus MTZ) is cost effective in perforated patients. The goal of this evaluation is to compare a historic regimen of cefoxitin (CFX) in nonperforated cases and ertapenem (ERT) in perforated and abscessed cases with CTX plus MTZ for all cases in terms of efficacy and cost. A retrospective review compared outcomes of nonperforated, perforated, and abscessed cases who received the historic regimen or CTX plus MTZ. Length of stay, time to afebrile, time to full feeds, postoperative abscess, and wound infection rates, inpatient readmissions, and antibiotic costs were evaluated. There were a total of 841 cases reviewed (494 nonperforated, 247 perforated, and 100 abscessed). Overall, the CTX plus MTZ group had a shorter time to afebrile (P < .001). Treatment groups did not differ in length of stay. Postoperative abscess rates were similar between groups (4.1% vs 3.3%, not significant). Other postoperative complications were similar between groups. Total antibiotic cost savings were over $110 000 during the study period (from November 2010 to June 2013). Both CFX and/or ERT and CTX plus MTZ result in low abscess and complication rates, suggesting both are effective strategies. Treatment with CTX plus MTZ results in a shorter time to afebrile, while also providing significant antibiotic cost savings. Ceftriaxone plus MTZ is a streamlined, cost-effective regimen in the treatment of nonperforated, perforated, and abscessed appendicitis. © The Author 2015.

Coronary perforation is an uncommon complication of angioplasty and is a challenging situation to manage. We describe a case of complex multivessel coronary angioplasty complicated by coronary perforation following balloon rupture that was successfully managed with a coronary stent graft. Delivery of the stent graft to the site of vessel rupture required deep intubation of an 8 Fr guiding catheter over the shaft of an inflated balloon. In addition to the availability of covered stents, it is essential to be familiar with various skills necessary to deploy these stents. Cathet Cardiovasc Intervent 2001;54:59-62.

The aim of this study is to report our experience with patients with intestinal perforation secondary to ingested foreign bodies (FBs) who were treated surgically at our institution. Between 2001 and 2015, a total of 38 pediatric patients with the diagnosis of intestinal perforation secondary to FBs were retrospectively reviewed. The series comprised 22 males and 16 females. The average age of the patients was 1.9 years. A definitive preoperative history of the ingestion of FBs was obtained for only eight patients. Crying and abdominal pain were the main clinical manifestations. Perforation repair was performed in 29 patients (76.3%), while enterostomy was utilized in five patients (13.2%) and enterectomy in four patients (10.5%). Five perforations occurred in the large intestine, and 33 perforations occurred in the small intestine with the most common site being the distal ileum. Of the 38 FBs recovered, 26 were food objects, while non-food objects were found in 12 patients. All patients recovered well, except one patient with an intestinal obstruction from adhesions that occurred approximately 1 month after discharge. Clinical performance of intestinal perforation secondary to FBs in children is atypical. Most perforations occur in the small intestine. Primary perforation repair is safe and effective, and better outcomes can be achieved.

Bladder perforations in children.

Bladder perforations in children occur due to several different reasons. In this clinical series study, we focused on bladder perforations due to the pelvic injury, and our aim also was to create awareness for a rare type of bladder injuries. This was a retrospective study of the patients who were treated in our clinic for bladder perforation between 2006 and 2011. We reviewed the documents of childhood bladder perforations, and demographic and clinical characteristics of the patients were obtained. No statistical analyses were used because of the limited number of cases. There were ten patients who suffered from bladder perforation in 5-year period; 5 were male, and 5 were female. The mean age of the patients was 4.35 years. Four patients (40%) experienced iatrogenic perforation and six patients (60%) experienced perforation due to the accident. Common symptoms were hematuria, abdominal tenderness, and inability to urinate. Three patients were diagnosed via emergency laparotomy, without any radiological examinations performed before surgery. Four patients suffered from the intraperitoneal perforation, three patients suffered from extraperitoneal injury and three of them both of intraperitoneal and extraperitoneal injuries. Mean recovery time for patients was 15 days. One patient developed a urinary tract infection and one newborn died due to accompanying morbidities. Nine patients were discharged from the hospital. If the patients had a pelvic injury, surgeons must pay attention for the bladder perforation. Isolated bladder perforations are rare, and they are generally associated with iatrogenic injuries. Clinicians should pay attention to findings such as anuria, inability to insert a urinary catheter, and free fluid in the abdomen in order to diagnose the bladder perforation in newborns. Novice surgeons should pay more attention to avoid causing iatrogenic bladder perforation during inguinal hernia repair.

It has been shown that the mineral trioxide aggregate (MTA) used to seal lateral/furcal perforations stimulates the deposition of newly formed cementum. Nevertheless, when the site of the perforation is contaminated, the healing process might occur under less favorable conditions. This study evaluated the repair healing process of noncontaminated and contaminated lateral perforations filled with MTA and the effect of previously filling the contaminated perforations with a bactericidal agent. Thirty lateral root perforations were prepared in endodontically treated dog's teeth, thus forming 3 groups with 10 specimens each. In group 1 the perforations were immediately sealed with MTA. In group 2 the perforations were left open for 7 days and thereafter sealed with MTA. In group 3 the perforations were left open for 7 days, filled temporarily with a calcium hydroxide-based paste for 14 days, and then sealed with MTA. The animals were killed after 90 days, and the pieces were prepared for histomorphologic and histomicrobiologic evaluations. The statistical analysis showed that group 1 had significantly better repair than groups 2 (P < .05) and 3 (P < .05), which validates the superior results obtained when MTA was immediately used to seal root perforations. Groups 2 and 3 had statistically similar repair to each other (P > .05). There were a larger number of cases of complete or partial biologic seal in group 1 compared with the contaminated groups. It might be concluded that the lateral root perforations sealed with MTA after contamination presented worse repair than the noncontaminated, immediately sealed perforations. The temporary filling with a bactericidal agent (calcium hydroxide-based paste) did not improve the repair of perforations exposed to contamination, and the contaminated groups presented similar results to each other.

Gastric heterotopias beyond the ligament of Treitz though rare, should be thought of in the differential diagnosis of polypoid lesions presenting with gastrointestinal bleed or obstructive symptoms especially in children and in the young. Here is a 24-year-old male with multifocal jejunal gastric heterotopias causing multiple strictures and perforation peritonitis. Patient presented with acute abdomen pain and an emergency laparotomy was performed revealing jejunum with multiple strictures and perforation, followed by jejunal resection. On gross examination polypoid mucosa was noted at the stricture sites which showed heterotopic gastric mucosa on microscopy. Jejunal gastric heterotopias are extremely rare with less than ten reported cases and those presenting with multiple strictures are even rarer. To our knowledge this is the second case of jejunal gastric heterotopia presenting with multiple strictures.

Vascular surgery through a groin incision may be associated with severe wound healing disorders in this sensitive area. There are many options to reconstruct the defect surgically. The choice of surgical reconstruction depends mainly on the individual status of vasculature, which is most often compromised in these patients. There are random pattern flaps, as well as perforator, pedicled flaps or microvascular flaps to choose from. We give an overview of plastic surgical solutions for groin defects, with a special focus on complex wounds after vascular surgical complications. We discuss advantages and disadvantages of different flaps with two case reports and also show alternatives. We demonstrate in two cases how the reconstruction of the groin defect was planned, taking into account the vascular status, and why we chose an innovative and seldom-used option in each case. The selected flaps, a pedicled fasciocutaneous ALT propeller flap and a perforator-based, pedicled abdominal advancement flap reconstructed the defects successfully. The surgical therapy for the reconstruction of groin defects should be chosen according to the individual vascular status to ensure safe and reliable blood supply. To guarantee the best possible reconstruction and avoid postoperative healing disorders and infections, less common flaps should also be considered.

We established a database on the incidence of intraoperative and postoperative complications associated with transurethral bladder tumor resection (TURBT) in an academic teaching setting, and we prospectively recorded all TURBTs performed by residents and fellows in our urology department. : We prospectively evaluated all TURBTs performed between November 2003 and October 2004. All cases were performed at least in part by residents and fellows under direct attending supervision at a single academic medical center with 3 different teaching hospitals. Intraoperative complications were recorded by the resident and attending surgeon at the completion of the operative procedure. At patient discharge from the hospital the data sheet was reviewed, and length of stay, postoperative transfusions and any other complications were recorded. A total of 173 consecutive TURBTs were performed by residents and fellows at 3 different teaching hospitals. There were 10 (5.8%) complications, including 4 (2.3%) cases of hematuria that required blood transfusion and 6 (3.5%) cases of bladder perforation. Of these 6 perforations 4 were small extraperitoneal perforations requiring only prolonged catheter drainage. These perforations were caused by residents in their first or third year of urology training. Two perforations were intraperitoneal, caused by a senior resident or a fellow, 1 of which required abdominal exploration to control bleeding. TURBT is a reasonably safe procedure when performed by urologists in training under direct attending supervision. The complication rate was 5.8%, however only 1 case required surgical intervention. Contrary to expected findings, more senior residents were involved in the complications, likely secondary to their disproportionate roles in more difficult resections.

Well known examples of acoustical dampers are the aero-engine liners, the IC-engine exhaust mufflers, and the liners in combustion chambers. These devices comprise wall perforations, responsible for their sound absorbing features. Understanding the effect of the flow on the acoustic properties of a perforation is essential for the design of acoustic dampers. In the present work the effect of a grazing-bias flow combination on the impedance of slit shaped wall perforations is experimentally investigated by means of a multi-microphone impedance tube. Measurements are carried out for perforation geometries relevant for in technical applications. The focus of the experiments is on the low Strouhal number (quasi-steady) behavior. Analytical models of the steady flow and of the low frequency aeroacoustic behavior of a two-dimensional wall perforation are proposed for the case of a bias flow directed from the grazing flow towards the opposite side of the perforated wall. These theoretical results compare favorably with the experiments, when a semi-empirical correction is used to obtain the correct limit for pure bias flow.

The incidence of gastrointestinal metastases from lung cancer is higher than previously thought as they have been reported in 2-14% of the cases in autopsy studies. However, clinically significant metastases are rare. Small bowel perforation secondary to metastatic non-small cell lung cancer is a very rare clinical entity. The aim of this study is to describe a case of ileal perforation in a patient with intestinal metastases of a non-small cell lung cancer, along with a review of the literature. A 57-year-old male with a history of non-small cell lung cancer was referred to our emergency department with signs and symptoms of acute surgical abdomen. A computed tomography scan demonstrated dilated small bowel loops, liver deposits, and signs of perforation of an intra-abdominal hollow viscus. Emergency exploratory laparotomy revealed diffuse purulent peritonitis and a perforated ileal tumor. A segmental small bowel resection and primary anastomosis were performed. Histological and immunohistochemical findings were consistent with a metastatic non-small cell lung carcinoma. Additional evaluation revealed widespread metastatic disease. Unfortunately, despite adjuvant treatment, the patient died of progressive disease 2 months after surgery. Small bowel perforation due to metastatic non-small cell lung cancer is a very rare clinical entity. The possibility of small bowel metastases should be kept in mind in patients with lung cancer presenting with an acute abdomen. Intestinal perforation occurs in advanced stages and is usually a sign of widespread disease. Aggressive surgery can provide effective palliation and may improve short-term survival. The prognosis is however dismal.

Non-traumatic perforation of common hepatic duct: Case report and review of literature HP.

Non-traumatic biliary perforation other than the gallbladder is extremely rare and most commonly seen in children in association with congenital biliary anomalies. We present a rare case of choledocholithiasis that progressed to spontaneous perforation of the common hepatic duct probably from ischemic necrosis caused by impaction of large biliary stones. A 62-year-old female presented with diarrhea and jaundice. She was found to have two 2.5cm stones in the common hepatic duct. Stones could not be extracted by ERCP, and placement of biliary stent was done to restore patency. The patient was lost to follow up and returned after three months with a new onset of similar symptoms. At that time ERCP and a stent change were done without resolution of the symptoms. Patient then underwent an open exploration and was found to have a free perforation in the lateral aspect of the common hepatic duct just at the bifurcation of the right and left hepatic radicals. Through this perforation stones were both extracted and cholangiogram showed free flow with the distal biliary stent. The stent was nowhere near the site of perforation which appeared to be caused by pressure necrosis from the impacted stones. Impacted stones in the biliary tree need to be extracted to avoid pressure necrosis and spontaneous perforation. ERCP and stent placement should be used only as temporizing measures to manage the acute obstructive phase. Definitive surgical intervention must follow initial biliary decompression to extract the impacted biliary stones and avoid complications. Copyright © 2017 The Authors. Published by Elsevier Ltd..

The trapezius myocutaneous flap is an established reconstructive option in head and neck cases The authors present their experience with 10 trapezius perforator flaps, all raised using a freestyle technique of perforator dissection, to successfully reconstruct both local and distant soft-tissue defects. Ten patients underwent soft-tissue reconstruction using trapezius perforator flaps. After mapping the perforator with a handheld Doppler device at the intersection of a horizontal line drawn 6 to 8 cm inferior to the scapular spine and a vertical line drawn 8 to 9 cm lateral to the midline of the back, perforator flaps were raised in a freestyle fashion, with complete preservation of the trapezius muscle. The flap can be pedicled into local defects or transferred as a free flap. Six flaps were elevated as pedicled flaps and four were transferred as free flaps. Flap size ranged from 6 × 4 cm to 25 × 15 cm. The pedicle length ranged from 4 to 14 cm. The pedicle originated from the dorsal scapular artery. In one case, the authors converted from a pedicled flap to a free flap secondary to insufficient pedicle length. All donor sites were closed directly. The follow-up period ranged from 4 months to 4 years. All of the flaps survived completely with no major complications, and no patients developed any shoulder dysfunction. The trapezius perforator flap is a reliable and versatile reconstructive option that can be used to repair both local and distant soft-tissue defects. The donor-site morbidity is minimal.

Even at the beginning of the new millennium, secondary peritonitis presents a common life-threatening condition associated with high mortality and morbidity. This article comments on epidemiology, diagnosis and general principles of surgical management in patients with secondary peritonitis. The demographic data, clinical findings and surgical outcome of 204 patients who had a confirmed generalized secondary peritonitis were analyzed retrospectively. Our approach was laparotomy, surgical control of contamination, antibiotic therapy and modern intensive care support. Acid peptic disease was the most common cause of perforation peritonitis 60 (29,41%), following by the perforated appendicitis 45 ( 22,06%). The faecal peritonitis and colon perforation were found in 42 patients (20,59%). The morbidity rate was 50%; 41 (40,2%) patients had more than one complication. The morbidity rate was significantly the highest in patients with colon perforation (n=38, 90%) (Hi-square=40,1; p<0,001). The overall mortality rate in our study was 8,82%. The mortality rate was significantly the highest among the patients with mesenteric ischemia in 4 patients (66,67%), followed by colon perforation in 10 cases (23,81%), and 4(6,6%) deaths due to gastro-duodenal perforation (Hi-square=45,7; p<0,001). This study has confirmed that the clinical presentation and outcome of the secondary peritonitis depend on duration of abdominal infection, the site of perforation and the general condition of the patient. Rapid surgical source control, modern intensive care and sepsis therapy may offer the chance of decreased morbidity and mortality of the intra-abdominal infections.

Appendicular mucocele, a cystic dilatation of the appendix, is a rare disease, but unfortunately about 1/10 of cases evolves into pseudomyxoma peritonei. We performed a prospective study between 1 January 2010 to 31 December 2014 in order to track the incidence, symptoms, and circumstances of diagnosis, treatment and evolution of these rare tumors. A total of seven patients underwent curative surgery for a mucocele of the appendix: one woman and six men with an average age of 59.71 years. Clinical signs, present in two cases, were uncharacteristic. Ultrasound performed in all cases, could guide diagnosis in 5 cases. CT performed in 5 cases diagnosed only two cases. All cases were operated on: the open approach was used in four cases and a minimally invasive in three cases. We performed two right colectomies, an open appendectomy associated to anterior resection of the rectum, two laparoscopic appendectomies and two appendectomies and cecum resection with stapler, one by open approach and one by a minimally invasive approach. Intraoperative spillage of mucinous tumor did not occur in any case. The mean hospital stay was 5.7 days. Postoperative complications were present in 1 case (14.2%): wound infection. The average follow-up period was 40.28 months. (Range 6 to 48 months). No tumor recurrence or readmission, such as pseudomyxoma peritonei, has occurred. Appendicular mucocele is a rare entity; it can be found incidentally and it can mimic acute appendicitis, appendicular plastron or cecum tumor. Once diagnosed, surgical treatment is required for fear of perforation, tumor evolution and the emergence of the rule of complications. Laparoscopic approach in selected cases can be used, accompanied by safety measures to avoid iatrogenic perforation and peritoneal and parietal seeding. Celsius.

The non-operative management of perforated peptic ulcer has previously been shown to be both safe and effective although it remains controversial. A protocol for non-operative management was set up in this hospital in 1989. Adherence to the guidelines in the protocol has been audited over a 6-year period with a review of outcome. The case-notes of patients with a diagnosis of perforated peptic ulcer were reviewed. Twelve guidelines from the protocol were selected for evaluation of compliance to the protocol. Forty-nine patients underwent non-operative treatment initially. Eight patients failed to respond and underwent operation. Complications included abscess formation (seven patients), renal failure (one), gastric ileus (one), chest infection (two), and cardiac failure and stroke (one). Four deaths occurred in this group. Adherence to certain protocol guidelines was poor, notably those concerning prevention of thromboembolism, use of antibiotics, use of contrast examination to confirm the diagnosis and referral for follow-up endoscopy. Two gastric cancers were detected on subsequent endoscopy. This experience demonstrates that non-operative treatment can be used successfully in a general hospital. Adherence to protocol guidelines was found to be variable and the protocol has therefore been simplified. This study highlights the need for an accurate diagnosis and the importance of follow-up endoscopy.

Amyand's hernia is a rare condition of inguinal hernia in which the appendix is incarcerated within the hernia sac through the internal ring. Complications include acute appendicitis and perforated appendicitis, which are rare in incidence, accounting for about 0.1% of cases. 1 These complications prove a diagnostic challenge due to their vague clinical presentation and atypical laboratory and radiological findings. Until recently, open appendectomy was the mainstay of treatment. Laparoscopic surgery offers a less invasive approach to confirming a diagnosis and serving as a therapeutic tool in equivocal cases. We report a case of a previously healthy 20-year-old male presenting with atypical signs and symptoms, as well as blood investigation results, and radiological findings of a perforated appendix within an Amyand's hernia. The patient was successfully managed using a minimally invasive laparoscopic appendectomy approach. Until recently, open appendectomy was considered the mainstay in the management of complicated Amyand's hernia. Laparoscopic surgery provides a new avenue for dealing with diagnostic uncertainty with advantages including faster recovery time, reduced hospital stay, and better quality of life. This case report highlights the concealing effects of an Amyand's hernia on a perforated appendix, the considerations required when an equivocal diagnosis present and the safe use of the minimally invasive laparoscopic surgery in the treatment of this rare condition.

A selective serotonin reuptake inhibitor is the most commonly prescribed antidepressant for the treatment of major depression. However, the mechanisms underlying the actions of selective serotonin reuptake inhibitors are not fully understood. In the dentate gyrus, chronic fluoxetine treatment induces increased excitability of mature granule cells (GCs) as well as neurogenesis. The major input to the dentate gyrus is the perforant path axons (boutons) from the entorhinal cortex (layer II). Through voltage-sensitive dye imaging, we found that the excitatory neurotransmission of the perforant path synapse onto the GCs in the middle molecular layer of the mouse dentate gyrus (perforant path-GC synapse) is enhanced after chronic fluoxetine treatment (15 mg/kg/day, 14 days). Therefore, we further examined whether chronic fluoxetine treatment affects the morphology of the perforant path-GC synapse, using FIB/SEM (focused ion beam/scanning electron microscopy). A three-dimensional reconstruction of dendritic spines revealed the appearance of extremely large-sized spines after chronic fluoxetine treatment. The large-sized spines had a postsynaptic density with a large volume. However, chronic fluoxetine treatment did not affect spine density. The presynaptic boutons that were in contact with the large-sized spines were large in volume, and the volumes of the mitochondria and synaptic vesicles inside the boutons were correlated with the size of the boutons. Thus, the large-sized perforant path-GC synapse induced by chronic fluoxetine treatment contains synaptic components that correlate with the synapse size and that may be involved in enhanced glutamatergic neurotransmission.

Damage to petals may have varying effects on the reproductive success of the plant. The variation may depend on the kind of damage to the corolla. Whether the damage is limited to the corolla, as is usually the case with nectar-robbing perforations, or extending to the reproductive parts of the flower, as in the case of florivory holes, might determine the extent of the effect on the plant's reproduction. We examined the various perforations in the flowers of Arctostaphylos pungens and correlated their presence with fruiting success. We found that though florivory holes were highly associated with damage to reproductive parts, fruiting success did not differ significantly between flowers with the two kinds of damage. Although nectar-robbing perforations were not associated with reduced number of fruit produced, they were significantly correlated with reduced number of fruit that contained seemingly viable seeds. The implications of our findings are discussed in the context of pollination and antagonism. PMID:26811740

2014-01-01

Background Epidermal cysts are commonly occurring masses usually less than 5 cm in diameter, but in predisposed patients, epidermal cysts can grow relatively large due to chronic infection. Methods From June 2002 to July 2010, 17 patients received 19 regional perforator-based island flaps to cover defects due to the excision of large epidermal cysts (diameter >5 cm) in the buttocks. Eight patients had diabetes, and seven had rheumatoid arthritis. The pedicles were not fully isolated to prevent spasms or twisting. Results All the flaps survived completely, except for one case with partial necrosis of the flap, which necessitated another perforator-based island flap for coverage. There were two cases of wound dehiscence, which were re-closed after meticulous debridement. There were no recurrences of the masses during follow-up periods of 8.1 months (range, 6-12 months). Conclusions In patients with large epidermal cysts and underlying medical disorders, regional perforator-based island flaps can be the solution to coverage of the defects after excision.

2006-01-01

Background Paraesophageal hernias are quite common and sometimes feared due to the risk of incarceration and strangulation of any herniated organ. The hereby reported combination of an incarcerated paraesophageal hernia containing a perforated peptic ulcer is extremely rare. Case presentation An elderly man with multiple medical conditions was admitted due to severe upper abdominal pain. The patient was found to have a paraesophageal hernia and underwent a laparotomy. In the hernia, a perforated benign peptic duodenal ulcer was found. The duodenal defect was over-sewn, the hernial defect was closed and the former hernial cavity was drained by a right-sided chest tube. The patient was discharged one month after surgery and was found to do well at follow-up one month after discharge. Conclusion This is the first report of a patient surviving the extremely rare and life-threatening combination of a perforated peptic duodenal ulcer in a paraesophageal hernia. PMID:16438731

The patient presented to emergency a day later with complaints of severe pain in the abdomen and abdominal distension following insufflation of high-pressure air jet through the anus. On examination, he had signs suggestive of perforation peritonitis and x-ray of the abdomen showed gas under the diaphragm. An emergency exploratory laparotomy was performed which revealed a 4-cm perforation in the sigmoid colon. Resection of the segment containing perforation along with the surrounding devitalised part was done with double-barrel colostomy. Reversal of colostomy was done after 8 weeks. Follow-up was uneventful. PMID:22854240

During the periodic physical checkups in 1997-2000, the authors have found eleven cases of nasal septum perforation among 2,869 welders in Ulsan, Korea. They have not suffered from diseases and conditions that could cause septum perforation such as tuberculosis, syphilis, and long-term use of topical corticosteroids. And also they did not have trauma history and surgical experiences on their nasal septum. To investigate the cause of septum perforation we reviewed the past history of pre-employment, the results of annual working environment survey and the material safety data sheets of welding rods and steels with which they have dealt. We also analyzed the concentration of several metals of welding fume and the concentration of blood and urinary chromium. In the result, we assumed that the nasal septum perforation of welders was due to chronic exposure to low-level hexavalent chromium.

Although endoscopic retrograde cholangiopancreatography (ERCP) is an effective modality for the diagnosis and treatment of biliary and pancreatic diseases, it is still related with several severe complications. We report on the case of a female patient who developed liver parenchyma perforation following ERCP. She underwent ERCP with sphincterotomy and extraction of a common bile duct stone. Shortly after ERCP, abdominal distension was identified. Abdominal computed tomography revealed intraabdominal air leakage and leakage of contrast dye penetrating the liver parenchyma into the space around the spleen. Since periampullary perforation related to sphincterotomy could not be denied, she was referred for immediate surgery. Obvious perforation could not be found at surgery. Cholecystectomy, insertion of a T tube into the common bile duct, placement of a duodenostomy tube and drainage of the retroperitoneum were performed. She did well postoperatively and was discharged home on postoperative day 28. In conclusion, as it is well recognized that perforation is one of the most serious complication related to ERCP, liver parenchyma perforation should be suspected as a cause.

The aim of our study was to demonstrate our experience regarding the surgical treatment of complications after foreign body ingestion. From 1997 to 2005, we treated 16 adult patients (mean age 44.8 years, range 21-77), who presented with complications after foreign body ingestion. The complications treated were perforation-peritonitis: n = 7 (44%), intra-abdominal abscess formation: n = 5 (31%), upper gastrointestinal bleeding: n = 3 (19%) and inflammatory mass formation: n = 1 (6%) patient. The diagnosis was made intra-operatively in 13 (81.3%) of the cases. The commonest anatomical position of the perforation was the large bowel, in 7 (43%) of the cases. Bony food parts were the commonest foreign bodies accidentally swallowed, in 9 (56%) patients. The median hospital stay was 7 days (2-18), while no death occurred in the postoperative period among the patients of the study. The postoperative morbidity rate was 22.2%. The most common complication after foreign body ingestion was the perforation of the gastrointestinal tract. The risk of perforation was higher when sharp foreign bodies were ingested. The pre-operative diagnosis was difficult, and it was usually achieved intra-operatively. (c) 2008 S. Karger AG, Basel

Background  An aberrant right subclavian artery (RSA) or arteria lusoria is the most common congenital abnormality of the aortic arch with an incidence of 0.3 to 3.0%. Case Description  We report a case of a perforated aneurysmal aberrant RSA, managed using a hybrid approach. Conclusion  In emergency cases with acute bleeding, we recommend an endovascular approach to avoid the lethal sequel of arterial leakage. Whenever possible, the pulsatile blood flow to the right arm should be restored. Management should be tailored to the nature of the aneurysmal aberrant RSA, patient's comorbidities, and concomitant lesions.

Mitral valve perforation is an uncommon but important complication of infective endocarditis. We report a case of a 65-year-old man who was diagnosed to have infective endocarditis of his mitral valve. Through the course of his admission he had a rapid development of hemodynamic instability and pulmonary edema secondary to acutely worsening mitral regurgitation. While the TEE demonstrated an increase in the size of his bacterial vegetation, Real Time 3D TEE was ultimately the imaging modality through which the valve perforation was identified. Through this case report we discuss the advantages that RT-3D TEE has over traditional 2D TEE in the management of valve perforation.

In many developing countries like Cameroon, unsafe abortion is a major public health problem. It can be responsible for severe complications including damage to the digestive and/or urinary tract, sepsis, and uterine perforation. Uterine perforation could be caused by most of the instruments that are used to evacuate the uterus. We report a case of apparent uterine perforation and subsequent migration of the plastic or rubber catheter into the peritoneal cavity during an abortion procedure performed in a setting that may have been unsafe. The discovery was made during a diagnostic laparoscopy indicated for secondary infertility of tubal origin 16 years after the abortion procedure. This is a rare clinical finding which is of therapeutic and diagnostic importance. To the best of our knowledge, a single similar case has been reported so far in the literature.

Iatrogenic injury of the intrathoracic oesophagus with bougie during sleeve gastrectomy

One of the most popular procedures amongst obesity surgery is the sleeve gastrectomy. There is international consensus regarding the usage of bougie for sleeve gastrectomy calibration. Nevertheless, there is a dissociation between the number of oesophageal perforations reported for any other oesophageal/gastric operation that requires bougie (e.g., anti-reflux surgery, incidence 1.2%) and bariatric surgery, where this complication seems to be almost a myth. Interestingly enough, the number of bariatric procedures is much higher than any other oesophageal/gastric surgery. This suggests that oesophageal perforations in obesity surgery are underreported. We report a case of injury of the intrathoracic oesophagus with bougie that occurred during a sleeve gastrectomy. In the infrequent case that the perforation is diagnosed during surgery, primary repair during the same intervention is highly recommended. Videothoracoscopy might be an effective option in case of necessity. We were able to complete the sleeve gastrectomy without increasing morbidity. PMID:28695879

Acquired perforating dermatosis (APD) represents a heterogenous group of skin disorders characterized histopathologically by transepithelial elimination (TEE) of dermal structures. APD is manifested clinically as multi-localized, papulo-nodular skin lesions accompanied by a refractory pruritus. APD typically coexists with long-term disorders, most often diabetic kidney disease (DKD). The paper presents a case of a 56-year-old male patient with chronic kidney disease (CKD) and concomitant acquired reactive perforating collagenosis (ARPC), which is a subtype of APD. Etiological theories of ARPC as well as current diagnostic and treatment principles in dermatosis were described. On the basis of the presented case report and the literature review attention was paid to diagnostic difficulties associated with APD. The assumption was made that APD can be an underdiagnosed disease and thus it is not treated correctly. According to the authors’ opinion, this is an important circumstance to popularize the knowledge about APD.

Esophageal Perforation After Transesophageal Echocardiogram.

Esophageal rupture after transesophageal echocardiogram (TEE) is a rare but life-threatening complication. Risk factors for perforation include spasm or hypertrophy of the cricopharyngeal sphincter, cervical arthritis, forward and left lateral bending of the distal esophagus, and esophageal disease such as inflammation or neoplasm. We present the case of a 80-year-old woman who developed perforation of her esophagus after TEE. Prior irradiation to the chest due to treatment for breast cancer and subsequent fibrosis probably contributed to this complication. Physicians referring patients for a TEE and physicians performing this procedure should be aware for the risk of perforation. The identification of risk factors and gentle maneuvering of the probe may prevent this severe, life-threatening complication.

We describe a case of perforated rectal cancer that became curatively resectable after FOLFOX4 chemotherapy. An 81- year-old woman was transferred to our hospital with a diagnosis of bowel perforation. She underwent emergency transverse colostomy, peritoneal lavage, and the insertion of indwelling drainage tubes, because the perforated rectal cancer was considered unresectable. After recuperation, she received chemotherapy consisting of FOLFOX4 and bevacizumab. Owing to a good response to the treatment after 4 months, rectal resection was achieved curatively. Wound dehiscence occurred as a postoperative complication. The patient chose not to receive adjuvant chemotherapy. Currently, she has been alive for more than 1 year 3 months after resection without recurrence.

A case of giant meconium pseudocyst secondary to ileum volvulus perforation is presented. Conventional radiographic features of meconium peritonitis with secondary meconium pseudocyst formation are well described. Our case is unusual in comparison to other cases reported in the literature and needs to be reported because the meconium pseudocyst presented without the typical ultrasound features (calcifications, polyhydramnios and ascites) and was initially identified as an abdominal mass. We describe the case of a 29-year-old Caucasian woman in her third trimester of pregnancy, in which an abdominal mass was detected in the fetus. The newborn was diagnosed in the early neonatal period with meconium pseudocyst secondary to ileum volvulus perforation. The prenatal appearance of a meconium pseudocyst can be complemented by other signs of bowel obstruction (if present) such as polyhydramnios and fetal bowel dilatation. This is an original case report of interest to all clinicians in the perinatology and fetal ultrasound field. We consider that the utility of this case is the recognition that a meconium pseudocyst might appear without the typical ultrasound features and should be considered as a differential diagnosis when an echogenic intra-abdominal cyst is seen.

fecal peritonitis due to colorectal perforation is a dramatic event characterized by high mortality. Our study aims at determining how results of sigmoid resection (eventually extended to upper rectum) for colorectal perforation with fecal peritonitis changed in recent years and which factors affected eventual changes. Seventy-four patients were operated on at our institution (2005-2014) for colorectal perforation with fecal peritonitis and were divided into two numerically equal groups (operated on before (ERA1-group) and after (ERA2-group) May 2010). Mannheim Peritonitis Index (MPI) was calculated for each patient. Characteristics of two groups were compared. Predictors of postoperative outcomes were identified. Postoperative overall complications, major complications, and mortality occurred in 59%, 28%, and 18% of cases, respectively, and were less frequent in ERA2-group (51%, 16%, and 8%, respectively), compared to ERA1-group (68%, 41%, and 27%, respectively; p = .155, .02, and .032, respectively). Such results paralleled lower MPI values in ERA2-group, compared to ERA1-group (23(16-39) vs. 28(21-43), p = .006). Using receiver operating characteristic analysis, the best cut-off value for MPI for predicting postoperative complications and mortality was 28.5. MPI>28 was the only independent predictor of postoperative overall (p = .009, OR = 4.491) and major complications (p < .001, OR = 23.182) and was independently associated with a higher risk of mortality (p = .016, OR = 13.444), as well as duration of preoperative peritonitis longer than 24 h (p = .045, OR = 17.099). results of surgery for colorectal perforation with fecal peritonitis have improved over time, matching a concurrent decrease of MPI values and a better preoperative patient management. MPI value may help in selecting patients benefitting from surgical treatment. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

Background Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice. Aim To demonstrate and to analyze the results of urgent esophagectomy in a series of patients with esophageal perforation. Methods A retrospective study of 31 patients with confirmed esophageal perforation. Most injuries were due to endoscopic dilatation of benign esophageal disorders, which had evolved with stenosis. The diagnosis of perforation was based on clinical parameters, laboratory tests, and endoscopic images. ‪The main surgical technique used was transmediastinal esophagectomy followed by reconstruction of the digestive tract in a second surgical procedure. Patients were evaluated for the development of systemic and local complications, especially for the dehiscence or stricture of the anastomosis of the cervical esophagus with either the stomach or the transposed colon. Results Early postoperative evaluation showed a survival rate of 77.1% in relation to the proposed surgery, and 45% of these patients presented no further complications. The other patients had one or more complications, being pulmonary infection and anastomotic fistula the most frequent. The seven patients (22.9%) who underwent esophageal resection 48 hours after the diagnosis died of sepsis. At medium and long-term assessments, most patients reported a good quality of life and full satisfaction regarding the surgery outcomes. Conclusions Despite the morbidity, emergency esophagectomy has its validity, especially in well indicated cases of esophageal perforation subsequent to endoscopic dilation for benign strictures.

Multifocal small bowel stromal tumours presenting with peritonitis in an HIV positive patient.

PubMed

Mansoor, Ebrahim

2014-01-01

The most common mesenchymal tumour of the gastrointestinal tract is stromal tumours (GISTs). Symptomatic GISTs can present with complications such as haemorrhage, obstruction and perforation. Complete surgical resection with negative margins is the mainstay of treatment but may be imprudent on emergent occasion. Tyrosine-kinase inhibitors (TKIs) have been revolutionary in the treatment of GISTs and have resulted in improved outcomes. A 41 year old HIV positive male presented with an acute history of abdominal pain and obstructive symptoms. Clinical examination revealed sepsis and peritonitis. One of the several small bowel tumours discovered at exploratory laparotomy was necrotic and perforated. The perforated tumour alone was resected and a small bowel internal hernia reduced. The patient made an uneventful recovery and will be considered for TKI therapy with a view to later re-operation. GISTs very rarely perforate. The pathophysiology of stromal tumour necrosis is poorly understood. Multifocality and small bowel location are poor prognosticators and may occur in the setting of familial GISTs, specific syndromes and sporadic cases. There is no established association between HIV and GISTs. Perforation occurs infrequently in ≤8% of symptomatic cases and poses increased risk of local recurrence. The surgical management of perforation takes precedence in an emergency. The surgeon must however take cognisance of the adherence to ideal oncologic principles where feasible. TKI therapy is invaluable if a re-exploration is to be later considered. Copyright © 2014 The Author. Published by Elsevier Ltd.. All rights reserved.

Pushing the envelope: laparoscopy and primary anastomosis are technically feasible in stable patients with Hinchey IV perforated acute diverticulitis and gross faeculent peritonitis.

Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. Provided an accurate patients selection, having the necessary haemodynamic stability, pneumoperitoneum is established with open Hasson technique and diagnostic laparoscopy is performed. If faeculent peritonitis (Hinchey IV perforated diverticulitis) is found, laparoscopy can be continued and a further three working ports are placed using bladeless trocars, as in traditional laparoscopic sigmoidectomy, with the addition of fourth trocar in left flank. The feacal matter is aspirated either with large-size suction devices or, in case of free solid stools, these can be removed with novel application of tight sealing endobags, which can be used for scooping the feacal content out and for its protected retrieval. After decontamination, a sigmoid colectomy is performed in the traditional laparoscopic fashion. The sigmoid is fully mobilised from the retroperitoneum, and mesocolon is divided up to the origin of left colic vessels. Whenever mesentery has extremely inflamed and thickened oedematous tissues, an endostapler with vascular load can be used to avoid vascular selective ligatures. Splenic flexure should be appropriately mobilised. The specimen is extracted through mini-Pfannenstiel incision with muscle splitting technique. Transanal colo-rectal anastomosis is fashioned. Air-leak test must be performed and drains placed where appropriate. The video shows operative technique for a single-stage, entirely laparoscopic, washout and sigmoid colectomy with primary colorectal anastomosis in a 35-year-old male patient with severe and diffuse free faeculent diverticular peritonitis (Hinchey IV). The patient was managed post-operatively according to enhanced recovery protocol and discharged home after 9 days, following an uneventful recovery. This case documents the technical feasibility of a minimally invasive single-stage procedure in a patient with Hinchey IV perforated diverticulitis with diffuse feacal peritonitis. The laparoscopic approach facilitated an effective decontamination of the peritoneal cavity, with a combination of large suction devices and aid of protected retrieval by closed endobags for effectively and completely laparoscopic removal of the solid feacal matter, offering clear advantages and excellent results even in such challenging cases. With necessary expertise, the sigmoid resection can be thereafter safely and entirely performed laparoscopically, the specimen extracted through mini-Pfannenstiel incision, and a laparoscopic intracorporeal transanal circular primary anastomosis performed.

This paper is concerned with the hydroelastic responses of a mat-like, rectangular very large floating structure (VLFS) edged with a pair of horizontal/inclined perforated anti-motion plates in the context of the direct coupling method. The updated Lagrangian formulae are applied to establish the equilibrium equations of the VLFS and the total potential formula is employed for fluids in the numerical model including the viscous effect of the perforated plates through the Darcy's law. The hybrid finite element-boundary element (FE-BE) method is implemented to determine the response reduction of VLFS with attached perforated plates under various oblique incident waves. Also, the numerical solutions are validated against a series of experimental tests. The effectiveness of the attached perforated plates in reducing the deflections of the VLFS can be significantly improved by selecting the proper design parameters such as the porous parameter, submergence depth, plate width and inclination angle for the given sea conditions.

To assess the safety and feasibility of laparoscopic and open repair of perforated peptic ulcer. Studies on comparison between laparoscopic repair(LR) and open repair(OR) of perforated peptic ulcer were collected. Data of operating time, blood loss, time to first flatus, postoperative hospital stay, postoperative complications and mortality between LR group and OR group were meta-analyzed using fixed effect model and random effect model. Nineteen studies including 1507 patients were selected for this study,including laparoscopic surgery(n=673) and open surgery(n=834). There were significant differences in blood loss, time to first flatus, postoperative hospital stay, wound infection rate and mortality between LR group and OR group. However, no significant differences existed in operative time, postoperative sepsis, pulmonary infection, abdominal abscess, and suture leakage between the two groups. Laparoscopic repair of perforated peptic ulcer is associated with improved outcomes in terms of less blood loss, quicker recovery, and lower rates of wound infection and mortality. Laparoscopic repair of perforated peptic ulcer is safe and feasible.

The management of perforated diverticulitis is a challenging aspect of general surgery. The prevalence of colonic diverticular disease has increased over the last decade and will continue to increase as the baby boomers add to the elderly population. Improvements in diagnostic imaging modalities, efforts to maintain intestinal continuity, and percutaneous drainage procedures now result in several alternatives when selecting a management strategy for complicated presentations. Specifically, laparoscopic lavage and resection with primary anastomosis have emerged as options for treatment of Hinchey III and IV diverticulitis in place of diversion in the appropriately selected patient. Percutaneous drainage of Hinchey II diverticulitis in centers equipped with interventional radiology provides another minimally invasive adjunct. The objective of this paper is to provide an update on the current management of perforated diverticulitis, with a focus on the advantages and disadvantages of the surgical options for the treatment of Hinchey III and IV diverticulitis.

Gas gangrene of the abdominal wall is a rare clinical occurrence with high rates of morbidity and mortality. The primary source of the infection is often unknown. To analyze the primary underlying intestinal etiologies and diagnostic approaches of gas gangrene of the abdominal wall, and to highlight specific treatment problems, particularly that of constructing a colostomy exteriorized through a massively infected abdominal wall. Seven cases of abdominal wall gas gangrene due to a gastrointestinal etiology were identified. (Cases arising from proctologic sources or related to recent abdominal surgery were excluded.) During the same period, 39 other patients presenting with abdominal wall gangrene from non-intestinal sources were treated. The etiologies were: perforated sigmoid diverticulitis (n=2), perforated appendicitis (n=1), acute pancreatitis with associated cecal perforation (n=1), and perforated colorectal cancer (n=3). Four of the seven patients died despite treatment (mortality of 57%). The clinical presentations of these seven cases demonstrate that a GI source must be suspected whenever a patient presents with abdominal wall gas gangrene, even when there are no specific GI symptoms. Imaging, particularly with CT scan, is essential both to visualize the extent of tissue necrosis and to reveal underlying primary GI pathology. This optimizes the surgical approach both by allowing for complete debridement and drainage of infected tissue, and by focussing the intervention on correction of the underlying primary GI source of infection.

The aim of this retrospective study was to assess the feasibility, safety and efficacy of the laparoscopic approach in the management of perforated peptic ulcers. From January 1997 to December 2002, all patients referred to our community hospital for abdominal surgical emergencies were routinely managed by laparoscopic surgery. A review was carried out on 39 consecutive patients suffering from perforated peptic ulcers with or without generalised peritonitis. The study population comprised 24 male and 15 female patients, aged 30 to 94 years (mean age: 62 +/- 18). Laparoscopic repair was attempted in all patients. Laparoscopy afforded the correct diagnosis in all cases. Laparoscopic peritoneal washout (irrigation and suction of the entire abdominal cavity) with simple suture of the perforation proved successful in 34 patients. An additional omental patching was performed in 15 of these cases. Conversion to conventional open surgery was necessary in 5 patients. The morbidity and mortality rates were 13% and 10%, respectively. The mean operative time was 77 minutes (range: 40-120) and the mean hospital stay 9 days (range: 3-22). Laparoscopic repair of perforated ulcers is technically feasible but requires sound experience in laparoscopic abdominal emergencies. This study shows that the mini-invasive procedure is safe and effective, offering a valid alternative to traditional laparotomy.

OBJECTIVE To explore the feasibility and effectiveness of V-Y advanced sense-remained posterior tibial artery perforator flap in repairing wound around the ankle. METHODS Between March 2012 and January 2015, 11 patients with wounds around the ankle were treated by V-Y advanced sense-remained posterior tibial artery perforator flap. There were 6 males and 5 females with a median age of 37 years (range, 21-56 years). The causes were traffic accident injury in 3 cases, thermal injury in 2 cases, burn in 2 cases, iatrogenic wounds in 2 cases, and local contusion in 2 cases. The disease duration ranged from 1 to 3 weeks (mean, 2 weeks). Injury was located at the medial malleolus in 4 cases, at the lateral malleolus in 3 cases, and at the heel in 4 cases. All had exposure of bone, tendon, or plate. The defect area ranged from 4 cmx2 cm to 5 cmx3 cm; the area of the flap ranged from 11 cmx4 cm to 15 cmx6 cm. Necrosis of distal flap occurred in 1 case after operation; re-operation to amputate the posterior tibial artery was given and the wound was repaired by proximal skin graft. Light necrosis of distal end was observed in 2 cases, and wound healed at 3 weeks after dressing. And other flaps successfully survived, and primary healing of wounds were obtained. The patients were followed up 6-24 months (mean, 11 months). The flaps were good in color, texture, and appearance. The ankle joint had normal activity. At last follow-up, 10 cases restored fine sense, and 1 case restored protective feeling with posterior tibial artery advanced flap after amputation. V-Y advanced sense-remained posterior tibial artery perforator flap has the advantages of reliable blood supply, simple operation, good appearance, and sensory recovery. Therefore, it is an ideal method to repair wound around the ankle.

2000-01-01

Plastic bread-bag clips have been identified as a cause of local perforation or obstruction at many sites in the gastrointestinal tract. This study is the largest case series yet reported, consisting of 3 cases presenting as small-bowel perforation, 1 case in which the clip was found incidentally in the small bowel at laparotomy during vascular surgery and 1 case in which the clip was found incidentally in the small bowel at autopsy. In all cases there was no radiographic evidence to suggest a foreign body in the gastrointestinal tract. People older than 60 years of age who have either partial or full dentures seem to be particularly at risk for the accidental ingestion of these devices. If accidentally ingested, plastic bread-bag clips represent a significant health hazard. As the population ages, small-bowel perforation secondary to ingestion of such clips may occur with increasing frequency. The authors recommend elimination or redesign of the clips, to prevent their being swallowed and becoming impacted in the small bowel or to allow them to be identified in the gastrointestinal tract by conventional radiography.

Spontaneous esophageal perforation, or Boerhaave's syndrome, is a life-threating condition which usually requires emergent surgery. An upside down stomach is defined as a gastric volvulus in a huge supradiaphragmatic sac. In general, this condition can result in ischemia and perforation of the stomach. This is the first report of a patient with Boerhaave's syndrome and an upside down stomach. A 79-year-old woman presented with sudden epigastric pain following hematemesis. Evaluation of the patient showed both an esophageal perforation and an upside down stomach. Surgical drainage and irrigation of the mediastinum and pleural cavities were undertaken emergently. Due to the concurrent gastric volvulus, a gastrostomy was placed to fix and decompress the stomach. The patient had an uneventful hospital course and was discharged. Boerhaave's syndrome is a rare but severe complication caused by excessive vomiting, due to a sudden elevation in intraluminal esophageal pressure resulting in esophageal perforation. Acute gastric volvulus can result in ischemia and perforation of the stomach, but has not previously been reported with esophageal perforation. The most likely mechanism associating an upside down stomach with Boerhaave's syndrome is acute gastric outlet obstruction resulting in vomiting, and subsequent esophageal perforation. Perforation of the esophagus as well as perforation of the stomach must be considered in patients with an upside down stomach although both upside down stomach and Boerhaave's syndrome are rare clinical entities.

Sivaram, P; Sreekumar, A

2018-04-01

Perforated peptic ulcer is one of the most common surgical emergencies worldwide. With the improvement in medical therapy for peptic ulcers, the number of elective surgical procedures has come down. However, the incidence of perforated peptic ulcer is still increasing and remains as a substantial health problem with significant postoperative morbidity and mortality. This study aimed to find out the association between various preoperative and intraoperative factors with the postoperative mortality and morbidity in patients operated for peptic ulcer perforation. This prospective observational study had a time based sample of 101 perforation peritonitis cases admitted to the surgical wards of a tertiary care center from February 2015 to January 2016 who underwent laparotomy, diagnosed to have peptic ulcer perforation and underwent simple closure with an omental patch. Data regarding age, gender, presenting complaints, time elapsed from the onset of symptoms to surgery, physical examination findings, comorbid diseases, laboratory and imaging findings, intraoperative findings, length of hospital stay, postoperative morbidity, and mortality were recorded and analyzed. Female gender, older age group, perforation surgery interval more than 36 h, and size of perforation more than 1 cm 2 were found to be significant factors influencing postoperative mortality and morbidity. Postoperative morbidity was also associated with comorbid diseases. Abnormal renal function on presentation was identified as an additional risk factor for postoperative morbidity and longer hospital stay. An understanding of these factors, identification of patients at risk and early intervention can help in reducing the postoperative morbidity and mortality in peptic ulcer perforation.

Background and Aims Angiosperms with simple vessel perforations have evolved many times independently of species having scalariform perforations, but detailed studies to understand why these transitions in wood evolution have happened are lacking. We focus on the striking difference in wood anatomy between two closely related genera of Adoxaceae, Viburnum and Sambucus, and link the anatomical divergence with climatic and physiological insights. Methods After performing wood anatomical observations, we used a molecular phylogenetic framework to estimate divergence times for 127 Adoxaceae species. The conditions under which the genera diversified were estimated using ancestral area reconstruction and optimization of ancestral climates, and xylem-specific conductivity measurements were performed. Key Results Viburnum, characterized by scalariform vessel perforations (ancestral), diversified earlier than Sambucus, having simple perforations (derived). Ancestral climate reconstruction analyses point to cold temperate preference for Viburnum and warm temperate for Sambucus. This is reflected in the xylem-specific conductivity rates of the co-occurring species investigated, showing that Viburnum lantana has rates much lower than Sambucus nigra. Conclusions The lack of selective pressure for high conductive efficiency during early diversification of Viburnum and the potentially adaptive value of scalariform perforations in frost-prone cold temperate climates have led to retention of the ancestral vessel perforation type, while higher temperatures during early diversification of Sambucus have triggered the evolution of simple vessel perforations, allowing more efficient long-distance water transport.

Reconstruction of Heel With Propeller Flap in Postfasciotomy and Popliteal Artery Revascularization State.

PubMed

Free flaps are still the gold standard for large defects of the lower limb, but propeller perforator flaps have become a simpler and faster alternative to free flaps because of some advantages such as reliable vascular pedicle, wide mobilization and rotation, great freedom in design, low donor site morbidity, and easy harvest with no requirement for anastomosis. But when the vessels show insufficient findings in preoperative evaluation using a Doppler probe or the vessel is injured, the surgeon should avoid performing free flap surgery to prevent flap failure and should select a propeller perforator flap as an alternative method on the condition that more than one perforator is intact. In this study, we report reconstruction of soft tissue defects of the heel with a pedicled propeller flap in postfasciotomy and popliteal artery revascularization state by making an incision on the central portion above the Achilles tendon, which can be covered by the posterior tibial artery perforator or the peroneal artery perforator based flaps. In conclusion, we showed that although the popliteal artery was injured, the soft tissue defect can be reconstructed using a perforator propeller flap if intact distal flow in the anastomosis site was confirmed. © The Author(s) 2015.

A 75-year-old man with vomiting and right abdominal pain was admitted to the Department of Surgery in our hospital. With a diagnosis of perforated duodenal ulcer, he was treated conservatively. On the day 8 of hospitalization, his general condition worsened and he underwent surgery. During operation, the perforated duodenal ulcer and paraduodenal fluid collection was observed, and percutaneous drainage was accordingly established. After this procedure, renal dysfunction was exacerbated and he was transferred to our department for endoscopic treatment. On day 28 of hospitalization, nasobiliary and nasopancreatic drainage was administered. Renal dysfunction gradually improved, and healing of the perforated duodenal ulcer was recognized on day 93. On day 112, the patient was discharged.

The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

Pseudolipomatosis in Endometrial Specimens Does Not Represent Uterine Perforation.

PubMed

Heller, Alexis

2017-02-01

Specimens of endometrial biopsies can sometimes present with an artifact within blood, composed of optically clear vacuoles mimicking adipose tissue, pseudolipomatosis. This artifact can be mistaken for adipose tissue and lead to an overdiagnosis of uterine perforation. We describe the case of pseudolipomatosis seen within the evacuated products of conception from a missed abortion. Areas of vacuolization in the blood clot mimicked adipose tissue. However, the vacuoles varied in size and did not contain adipocytes. Familiarity with this artifact will lead to avoidance of overdiagnosis of adipose tissue and uterine perforation in curettage specimens.

In recent years, retrograde approach for chronic total occlusions has rapidly evolved, enabling a higher rate of revascularization success. Compared to septal channels, epicardial collaterals tend to be more tortuous, more difficult to negotiate, and more prone to rupture. Coronary perforation is a rare but potentially life-threatening complication of coronary angioplasty, often leading to emergency cardiac surgery. We report a case of a retrograde chronic total occlusion revascularization through epicardial collaterals, complicated by both retrograde and antegrade coronary perforation with tamponade, and successfully managed by coil embolization.

Perforation of the bladder during transurethral resection is a worrisome complication for most urologists. Little is known about the consequences of seeding of tumor cells into the peritoneum or retroperitoneum. We reviewed several hospital patient databases as well as the literature to determine the outcome of such situations. We performed a local multi-institutional case and MEDLINE review using key words, such as bladder neoplasm, neoplasm seeding, perforation, rupture, transurethral resection, peritonitis and tumor. We also contacted several urologists and oncologists at major cancer centers in the United States and Europe regarding the incidence and followup of perforated/violated bladder cancer cases. There were 16 bladder violations in the presence of transitional cell carcinoma, including 2 partial cystectomies that had negative margins and no subsequent metastatic recurrences, a bladder tumor that was detected during suprapubic prostatectomy and perforations during transurethral resection (extraperitoneal in 4 cases and intraperitoneal in 9). Two patients died of sepsis and existing metastatic disease, respectively. The only recurrence among the remaining 11 patients developed after intraperitoneal bladder perforation during transurethral resection for Ta grade 2 tumor. Several anecdotal reports discussed local and distal tumor recurrences, suggesting that even superficial transitional cell carcinoma can behave aggressively if grown in an environment outside the bladder. However, these reports are rare. Any benefit of prophylactic chemotherapy was not proved. While perforation of the bladder during transurethral resection for cancer and the possibility of tumor implantation are matters of concern, our review demonstrates that few patients return with an extravesical tumor recurrence either locally or distally compared to those with a nonruptured bladder after resection. Although our patient sample is small and there are a limited number of reports in the literature, the risk of recurrence still exists and the urologist should be aware of its possibility. Since recurrences are usually rapid, they may easily manifest to the urologist at followup. However, one should also consider chest x-rays and/or computerized tomography to rule out recurrences that are not clinically obvious.

Perforated marginal ulcers after laparoscopic gastric bypass.

Perforated marginal ulcer (PMU) after laparoscopic Roux-en-Y gastric bypass (LRYGB) is a serious complication, but its incidence and etiology have rarely been investigated. Therefore, a retrospective review of all patients undergoing LRYGB at the authors' center was conducted to determine the incidence of PMU and whether any causative factors were present. A prospectively kept database of all patients at the authors' bariatric center was retrospectively reviewed. The complete records of patients with a PMU were examined individually for accuracy and analyzed for treatment, outcome, and possible underlying causes of the marginal perforation. Between April 1999 and August 2007, 1% of the patients (35/3,430) undergoing laparoscopic gastric bypass experienced one or more perforated marginal ulcers 3 to 70 months (median, 18 months) after LRYGB. The patients with and without perforation were not significantly different in terms of mean age (37 vs 41 years), weight (286 vs 287 lb), body mass index (BMI) (46 vs 47), or female gender (89% vs 83%). Of the patients with perforations, 2 (6%) were taking steroids, 10 (29%) were receiving nonsteroidal antiinflammatory drugs (NSAIDs) at the time of the perforation, 18 (51%) were actively smoking, and 6 of the smokers also were taking NSAIDs. Eleven of the patients (31%) who perforated did not have at least one of these possible risk factors, but 4 (36%) of the 11 patients in this group had been treated after bypass for a marginal ulcer. Only 7 (20%) of the 35 patients who had laparoscopic bypass, or 7 (0.2%) in the entire group of 3,430 patients, perforated without any warning. There were no deaths, but three patients reperforated. The incidence of a marginal ulcer perforating after LRYGB was significant (>1%) and appeared to be related to smoking or the use of NSAIDs or steroids. Because only 0.2% of all patients acutely perforated without some risk factor or warning, long-term ulcer prophylaxis or treatment may be necessary for only a select group of high-risk patients.

Perforated appendicitis can result in potentially serious complications requiring prolonged medical care. The optimal approach to successfully managing this condition is controversial. Review of 80 consecutive cases of pediatric acute perforated appendicitis with intra-abdominal infection (IAI) medically managed with parenteral antibiotics and percutaneous drainage (PD) during a 7-year period. All patients received broad spectrum parenteral antibiotic therapy. One-third were hospitalized for >2 weeks. IAI was identified on admission in 60% compared with developing during hospitalization in 40% of cases. Before performing PD, the mean duration of antibiotic therapy in those who developed IAI during hospitalization was 6 days. IAI cultures yielded 127 bacterial isolates; polymicrobial infection occurred in 65% of cases. Only 7% of aspirates were sterile. The most common pathogens were Escherichia coli (82%), of which 5 isolates exhibited extended-spectrum β-lactamase production, and streptococci (40%). At the time of PD, 60% were febrile (mean duration of in-hospital fever, 7.5 days); 67% defervesced within 24 hours after the procedure. Posthospitalization abdominal complications (recurrent IAI or appendicitis) occurred in one-third of patients. Children with perforated appendicitis and IAI often have a complicated and prolonged clinical course. Medical management consisting solely of parenteral antibiotic therapy is frequently ineffective in resolving IAI. Rapid clinical improvement commonly follows PD.

To investigate the effectiveness of pedicled superior gluteal artery perforator bilateral quadrilobed flaps for repairing large sacrococcygeal pressure sores. Between June 2003 and August 2011, 6 paraplegia patients with large sacrococcygeal pressure sores were repaired with the pedicled superior gluteal artery perforator bilateral quadrilobed flaps. There were 2 males and 4 females with an average age of 45.6 years (range, 37-62 years). The mean disease duration was 8.4 months (range, 3-26 months). According to National Pressure Ulcer Advisory Panel (NPUAP) standard, 6 cases rated as degree IV. The size of pressure sores ranged from 15 cm x 13 cm to 18 cm x 16 cm. The size of flaps ranged from 18 cm x 14 cm to 21 cm x 15 cm. After operation, all flaps survived successfully. The wounds healed by first intention in 5 cases; partial dehiscence of incision occurred in 1 case, which was cured after dressing change for 26 days. Six patients were followed up 6-24 months (mean, 12.5 months). The appearance and texture of the flaps were smooth and soft with good elasticity and no ulceration. Pedicled superior gluteal artery perforator bilateral quadrilobed flaps can repair large sacrococcygeal pressure sores. The appearance of flaps is smooth and has good compression-resistance effect.

Multiple magnet ingestion during childhood may result in emergency situations. A single magnet may be discharged with intestinal peristalsis, but multiple magnets may stick together and cause significant intestinal complications. Here we present a case with intestinal perforation due to ingestion of multiple magnets and metal pieces. An eight-year-old girl presented with abdominal pain and vomiting. She had abdominal tenderness and defense on the physical examination. Abdominal X-ray showed air and fluid levels. Metallic images were not considered at first as important in the diagnosis. Abdominal ultrasonography was reported as acute appendicitis. During the abdominal exploration, the appendix was normal, but there were dense adherences around the ileum and cecum. After adhesiolysis, intestinal perforations were seen in the cecum and 15 and 45 cm proximal to the cecum. Magnet and metal pieces were present in the perforated segments. Wedge resection and primary repair was performed. There were no postoperative complications, and she was discharged on the postoperative fifth day. Pediatric surgeons should be aware of the complications of multiple magnet ingestion. If the patient has a history of multiple magnet ingestion, follow-up with daily abdominal X-rays should be done, and in cases where magnets seem to cluster together or if acute abdominal signs develop, surgical exploration should be considered.

Puncture or laceration of the pulmonary, intercostal, or peripheral vessels is an uncommon, but potentially life-threatening, complication of thoracentesis, which has been reported to result in severe haemothorax in 75% of patients. Damage to these vessels typically requires surgical intervention or intra-arterial embolisation. We report the successful non-surgical management of an unusual case of pulmonary artery perforation without concomitant haemothorax in an 82-year-old man who underwent thoracentesis. PMID:20529518

Laparoscopic endoloop technique – A novel approach of managing iatrogenic caecal perforation and literature review

PubMed Central

Merali, N.; Hussain, A.

2015-01-01

Introduction An iatrogenic caecal perforation is rare, but a serious complication associated with significant morbidity and mortality. We present a 4 min and 50 s video on a new improvisation undertaken during laparoscopic management of post-polypectomy caecal perforation. Presentation of case Our patient presented with an acute abdomen following endoscopic polypectomy. At surgery, the site of caecal perforation was close to the appendicular base with devitalization tissue, secondary to diathermy usage. The hallmark of safety within this novel technique included fresh healthy tissue margins within the endoloop (detachable snare ligation) and ensuring no ischemic tissue was gathered. Complete freeing of the appendix and meso-appendicular base was required and securing three endoloops proximal to the site of perforation. The post-operative course was uneventful. Discussion The World Society of Emergency Surgery (WSES) 2013 guidelines suggested an early laparoscopic approach is a safe and effective treatment for colonoscopy-related colonic perforation. There are no national guidelines and the management is dictated by the clinical condition of the patient, co-morbidity, size and site of perforation as well as the scale of bowel preparation, and surgical experience. Conclusion The endoloop technique described, undertaken during a laparoscopy is a novel approach. It is a simple and effective method, reminding clinicians to adapt techniques when necessary. Nevertheless, it is only limited to perforations around the appendicular base. PMID:25723744

Peritoneal mesothelioma is a rare disease associated with poor prognosis. Acute abdomen as the first presentation is an extremely rare occurrence. We report an exceptional case of a patient who was found to have a jejunal perforation due to infiltration of peritoneal mesothelioma. A 62-year-old man was admitted with clinical signs of peritonitis. Computerized tomographic scans showed a mass distal to the ligament of Treitz, thickening of the mesentery and a small amount of ascites. Emergency laparotomy revealed a perforated tumor 15 cm distal to the ligament of Treitz and diffuse peritoneal disease. Segmental small bowel resection and suboptimal cytoreduction were performed. Histopathology and immunohistochemistry showed infiltration of malignant mesothelioma. During the postoperative period pleural mesothelioma was also diagnosed. Despite adjuvant chemotherapy, the patient died of disseminated progressive disease 7 months after surgery. Peritoneal mesothelioma is a rare malignancy with grim prognosis. Small bowel involvement is a poor prognostic indicator. Our case of a small bowel perforation due to direct infiltration by peritoneal mesothelioma appears to be the first reported in the English literature.

Perforating internal root resorption repaired with mineral trioxide aggregate caused complete resolution of odontogenic sinus mucositis: a case report.

An extensive perforating internal root resorption accompanied by apical periodontitis and odontogenic sinus mucositis was detected on preoperative cone-beam computed tomographic scans in a first maxillary molar. After the chemomechanical debridement of the root canals, calcium hydroxide was placed as a temporary dressing for 7 days. Mineral trioxide aggregate was used to fill the perforation site with the aid of a surgical microscope. At the next visit, the root with the resorption defect was filled with warm vertical compaction of gutta-percha. A control cone-beam computed tomographic scan acquired 6 months after the endodontic treatment revealed complete resolution of the sinus retention cyst. Moreover, the patient's frequent otolaryngologic disturbances ceased. The tooth was functional with satisfactory clinical and radiographic results after 12 months. Based on the results of this case, successful repair of an extensive, perforating internal resorption with mineral trioxide aggregate may lead to complete resolution of apical periodontitis and maxillary sinus retention cyst.

The surgical treatment for perforated peptic ulcers can be safely performed laparoscopically. The aim of the study was to define simple predictive factors for conversion and septic complications. This retrospective case-control study analyzed patients treated with either laparoscopic surgery or laparotomy for perforated peptic ulcers. A total of 71 patients were analyzed. Laparoscopically operated patients had a shorter hospital stay (13.7 vs. 15.1 days). In an intention-to-treat analysis, patients with conversion to open surgery (analyzed as subgroup from laparoscopic approach group) showed no prolonged hospital stay (15.3 days) compared to patients with a primary open approach. Complication and mortality rates were not different between the groups. The statistical analysis identified four intraoperative risk factors for conversion: Mannheim peritonitis index (MPI) > 21 (p = 0.02), generalized peritonitis (p = 0.04), adhesions, and perforations located in a region other than the duodenal anterior wall. We found seven predictive factors for septic complications: age >70 (p = 0.02), cardiopulmonary disease (p = 0.04), ASA > 3 (p = 0.002), CRP > 100 (p = 0.005), duration of symptoms >24 h (p = 0.02), MPI > 21(p = 0.008), and generalized peritonitis (p = 0.02). Our data suggest that a primary laparoscopic approach has no disadvantages. Factors necessitating conversions emerged during the procedure inhibiting a preoperative selection. Factors suggesting imminent septic complications can be assessed preoperatively. An assessment of the proposed parameters may help optimize the management of possible septic complications.

No ideal and generally accepted prognostic factors and scoring systems exist to determine the prognosis of peritonitis associated with colonic perforation. This study was designed to investigate prognostic factors and evaluate the various scoring systems to allow identification of high-risk patients. Between 1996 and 2003, excluding iatrogenic and trauma cases, 26 consecutive patients underwent emergency operations for colorectal perforation and were selected for this retrospective study. Several clinical factors were analyzed as possible predictive factors, and APACHE II, SOFA, MPI, and MOF scores were calculated. The overall mortality was 26.9%. Compared with the survivors, non-survivors were found more frequently in Hinchey's stage III-IV, a low preoperative marker of pH, base excess (BE), and a low postoperative marker of white blood cell count, PaO2/FiO2 ratio, and renal output (24h). According to the logistic regression model, BE was a significant independent variable. Concerning the prognostic scoring systems, an APACHE II score of 19, a SOFA score of 8, an MPI score of 30, and an MOF score of 7 or more were significantly related to poor prognosis. Preoperative BE and postoperative white blood cell count were reliable prognostic factors and early classification using prognostic scoring systems at specific points in the disease process are useful to improve our understanding of the problems involved.

The lack of soft tissue that is available for medial leg and foot defect reconstructions presents a challenge for plastic surgeons. The saphenous neurofasciocutaneous perforator flap application presents an effective alternative to local flap transfers. However, the venous flow and pedicle twisting problems are still disputed. Here, we present our experiences with modified cutaneous pedicles with a single perforator pedicle, which improves the venous flow and the pedicle twisting problem. This study was conducted from June 2007 through September 2011, and a total of 15 patients with lower medial leg and foot defects were included. There were 11 men and four women. An asymmetric 'propeller' flap was planned around a perforator that was adjacent to the defects, which was preoperatively confirmed by Doppler. The perforator was sufficiently dissociated to allow for the flap to be turned towards the defects. We preserved some distal skin and subcutaneous tissue from the short side of the 'propeller' to cover some donor site regions, and other regions were covered with split thickness skin grafts. The follow-up period ranged from 3 to 12 months. An infection occurred in one case. Partial flap necrosis was noted in two cases. The other 12 flaps completely survived and matched the recipient sites with regard to colour, texture and thickness. The single perforator greater saphenous neuro-veno-fasciocutaneous propeller flap is an effective solution for medial leg and foot defects, and it has a large rotation arc and a satisfactory aesthetic result. © 2015 Royal Australasian College of Surgeons.

Coronary perforation (CP) is a rare, but sometimes lethal, complication of percutaneous catheter intervention (PCI). We reviewed surgically-treated cases of type 3 CP during PCI. From 2007 to 2010, 5 patients underwent surgical repair for type 3 CP (3 men, 2 women; mean age, 74 years). The mean number of diseased coronary branches was 2.6 and the mean SYNTAX score was 45. The target lesions were the left anterior descending artery in 4 cases and the right coronary artery in 1 case. Types of American Heart Association/American College of Cardiology classification were type B2 in only one case and type C in 4 cases. The causes of perforation were balloon inflation in 4 patients and rotational atherectomy in 1 patient. The in-hospital mortality rate was 20%. In the cases of CP associated with balloon inflation, coronary lacerations were so severe that re-bleeding occurred even if the covered stent could temporarily achieve hemostasis, and percutaneous cardiopulmonary support and emergency surgery were required. CP induced by balloon inflation tends to result in a serious condition compared with rotablator-induced CP. Surgery should be immediately performed even after covered stent implantation if there is any possibility of re-bleeding in the case of balloon-induced type 3 CP.

We present a case of perforating folliculitis in a patient treated with nilotinib, a kinase inhibitor. A 48-year-old man presented with a severely pruritic follicular rash for several months that started after reaching a complete molecular response of his myeloid chronic while treated with nilotinib. Clinical examination showed predominantly follicular pinpoint papules on trunk and proximal extremities and a biopsy showed a slightly dilated hair follicle with a focal disruption of the infundibular follicular epithelium. Other diseases related with perforating folliculitis were ruled out. The temporary relationship between the treatment and the appearance of the lesions suggests some pathogenic role of nilotinib. Relationship with nilotinib is also supported by previous similar cases related with sorafenib therapy. Both drugs inhibit c-kit and PDGF-R. PDGF-R has been previously involved in murine and human in vitro models of hair follicle cycle. So, our case supports in vivo the previous evidence of the importance of PDGF-R, a kinase, in the normal hair follicle development.

Root perforations are accidental events that may occur during the treatment, causing tissue inflammation and alveolar bone loss of integrity of the periodontium. In such cases, the radiological evidence is fundamental in the formulation of the diagnosis, in the choice of therapy (surgical or non-surgical) and finally for the assessment of prognosis of the dental element. In non-surgical treatment of endodontic lesions, the material used for the repair of the defect root should have biocompatibility, antibacterial activity, ability to induce healing of periodontal tissues and radiopacity. The Mineral Trioxide Aggregate (MTA) is a silicate-based cement introduced in dental clinical practice with good radiopacity, biocompatibility and bone induction. This article describes the use of MTA in endodontic repair of a perforation of the middle third root and the success of non-surgical treatment was dimonstrated radiographicaly.

To compare topical natamycin vs voriconazole in the treatment of filamentous fungal keratitis. This phase 3, double-masked, multicenter trial was designed to randomize 368 patients to voriconazole (1%) or natamycin (5%), applied topically every hour while awake until reepithelialization, then 4 times daily for at least 3 weeks. Eligibility included smear-positive filamentous fungal ulcer and visual acuity of 20/40 to 20/400. The primary outcome was best spectacle-corrected visual acuity at 3 months; secondary outcomes included corneal perforation and/or therapeutic penetrating keratoplasty. A total of 940 patients were screened and 323 were enrolled. Causative organisms included Fusarium (128 patients [40%]), Aspergillus (54 patients [17%]), and other filamentous fungi (141 patients [43%]). Natamycintreated cases had significantly better 3-month best spectacle-corrected visual acuity than voriconazole-treated cases (regression coefficient=0.18 logMAR; 95% CI, 0.30 to 0.05; P=.006). Natamycin-treated cases were less likely to have perforation or require therapeutic penetrating keratoplasty (odds ratio=0.42; 95% CI, 0.22 to 0.80; P=.009). Fusarium cases fared better with natamycin than with voriconazole (regression coefficient=0.41 logMAR; 95% CI,0.61 to 0.20; P<.001; odds ratio for perforation=0.06; 95% CI, 0.01 to 0.28; P<.001), while non-Fusarium cases fared similarly (regression coefficient=0.02 logMAR; 95% CI, 0.17 to 0.13; P=.81; odds ratio for perforation=1.08; 95% CI, 0.48 to 2.43; P=.86). Natamycin treatment was associated with significantly better clinical and microbiological outcomes than voriconazole treatment for smear-positive filamentous fungal keratitis, with much of the difference attributable to improved results in Fusarium cases. Voriconazole should not be used as monotherapy in filamentous keratitis. clinicaltrials.gov Identifier: NCT00996736

Caecal perforation is a life-threatening complication of large bowel obstruction with a reported mortality of 34% to 72%. This case describes the novel use of percutaneous needle caecostomy as a life-saving measure to prevent imminent caecal perforation in a 68-year-old lady with large bowel obstruction secondary to an incarcerated incisional hernia. After careful review of computed tomography images and measurement of distances from the abdominal wall to the caecum, the patient's caecum was decompressed in the emergency department using a needle under local anaesthetic. The patient subsequently underwent laparoscopic hernia repair and had an uncomplicated recovery. When conducted safely and with precision in an appropriate patient, percutaneous needle caecostomy can provide immediate symptom relief, reduce risk of caecal perforation, and allow a laparoscopic surgical approach.

Antibiotics are used both pre and post-operatively in acute appendicitis for preventing wound infection. It has been observed that the routine use of post-operative antibiotics is not necessary in cases of non-perforated appendicitis as only prophylactic antibiotics are sufficient to prevent wound infection. The aim of this study was to see the frequency of wound infection in non-perforated appendicitis with single dose preoperative antibiotics only. This observational study was conducted at the Department of Surgery, Ayub Medical College, Abbottabad from May to November 2014. A total of 121 patients with non-perforated appendicitis were included in the study. Only single dose preoperative antibiotics were used. The patients were followed for wound infection till 8th post-operative day. 121 patients, 56 (46.28%) male and 65 (53.72%) female were included in the study. The mean age of patients was 27.41 +/- 7.12 years with an age range of 18 to 45 years. In the entire series, 7 (5.78%) patients developed wound infection. The infection was minor which settled with conservative therapy. Prophylactic antibiotics were found efficacious in 114 (94.21%) patients. There was no significant association between wound infection and age and gender. Single dose preoperative antibiotics were found effective in controlling post-operative wound infection without the need of extending the antibiotics to post-operative period in cases of non-perforated appendicitis.

Although the perforator free flap is now a standard choice for head and neck reconstruction, problems such as microvascular complications, insufficient volume support for the defect, and fistula formation occur. We revisited a de-epithelialized concept for superficial circumflex iliac artery and anterolateral thigh perforator free flap to overcome these problems. We applied the de-epithelized perforator free flaps in 35 cases among 761 microsurgical head and neck reconstructions and investigated flap characteristics (length gain of pedicle, flap size, and volumetric analysis) and outcomes (flap failure, partial flap necrosis, hematoma, infection, and fistula). Satisfactory results were achieved regarding flap survival, volumetric compensation, and fistula formation. Flaps were transferred successfully in all patients, although 1 patient underwent revisional operation due to venous congestion. Transferred flap volume was significantly higher than the resected tumor volume (p < 0.01), which suggests volume augmentation in the destroyed neck envelope and a protective role against adjuvant radiation. Minor dehiscence and bleeding were seen in two cases, and no other complications were identified. The de-epithelialization concept for perforator free flap is helpful to overcome obstacles related to traditional free flaps in terms of flap survival and volumetric augmentation in head and neck reconstructions.

Current data on upper extremity propeller flaps are poor and do not allow the assessment of the safety of this technique. A systematic literature review was conducted searching PubMed, EMBASE, and the Cochrane Library electronic databases, and the selection process was adapted from the preferred reporting items for systematic reviews and meta-analysis statement. The final analysis included ten relevant articles involving 117 flaps. The majority of flaps were used for the hand, distal wrist, and elbow. The radial artery perforator and ulnar artery perforator were the most frequently used flaps. The were 7% flaps with venous congestion and 3% with complete necrosis. No difference in complications rate was found for different flaps sites. Perforator-based propeller flaps appear to be an interesting procedure for covering soft tissue defects involving the upper extremities, even for large defects, but the procedure requires experience and close monitoring.

Renal excretion of orally ingested gastrografin has rarely been reported on computed tomography (CT). We studied the unenhanced scans of 82 patients with bowel disorders or perforation to assess the prevalence of urinary contrast material (CM) in various bowel diseases. We also assessed the clinical significance of this sign. In addition, we reviewed the unenhanced CT scans of 100 randomly selected patients without bowel diseases as a control group. Twenty-nine of the 58 patients with bowel diseases, six of nine with free perforation, and one of 15 with covered perforation had CM in the urinary tract. None of the 100 without bowel disease showed urinary CM. Statistical analysis was done by using the Fisher's exact test. The prevalence of urinary CM was highest in inflammatory bowel disease, radiation enteritis, and free perforation (p < 0. 0001). This study shows that the CT finding of orally ingested gastrografin in the urinary tract differentiates patients with bowel disease from those without.

Abdominal compartment syndrome (ACS) is defined as an increased intra-abdominal pressure with adverse physiologic consequences. Abdominal compartment syndrome caused by perforated peptic ulcer is rare owing to early diagnosis and management. Delayed recognition of perforated peptic ulcer with pneumoperitoneum, bowel distension, and decreased abdominal wall compliance can make up a vicious circle and lead to ACS. We report a case of perforated peptic ulcer associated with ACS. A 74-year-old man with old stroke and dementia history was found to have distended abdomen, edema of bilateral legs, and cyanosis. Laboratory tests revealed deterioration of liver and kidney function. Abdominal compartment syndrome was suspected, and image study was arranged to find the cause. The study showed pneumoperitoneum, contrast stasis in heart with decreased caliber of vessels below the abdominal aortic level, and diffuse lymphedema at the abdominal walls. Emergent laparotomy was performed. Perforated peptic ulcer was noted and the gastrorrhaphy was done. The symptoms, and liver and kidney function improved right after emergent operation.

1984-09-25

A fluid injection lozenge comprises two tubes supporting a perforate member forming a cage enclosing the space between the tubes. Each tube has a series of perforations along its length so that a fluid can be injected, through the tube, into the enclosed space. The lozenges are of use in catalytic converters of either the axial or radial flow design. In the case of a radial flow converter, a plurality of tubes are provided, preferably connected in pairs by the perforate members, to form a squirrel cage structure, disposed in the catalyst bed.

Ileoscopy with mucosal biopsy is fundamental in the management and surveillance of inflammatory bowel disease patients and intestinal transplant recipients. There is a paucity of data describing the risks of ileoscopy in the presence of a prolapsed stoma. Parastomal hernias are frequently associated with prolapsed stomas. We report the first case of perforation during ileoscopy in the setting of a prolapsed stoma and unrecognized parastomal hernia. Recognition of parastomal hernia associated with stoma prolapse is of paramount importance in patients undergoing ileoscopy as it may increase the risk of perforation. PMID:27807575

Acquired perforating dermatosis (APD) is an uncommon cutaneous perforating disorder. We report a patient on hemodialysis who developed skin eruption and jaundice. He underwent FDG PET/CT under suspicion of biliary malignancies. PET/CT showed no significant abnormal uptake except of multiple FDG-avid nodules in the skin. The eruption he had was histopathologically diagnosed as APD by skin biopsy. His case suggests that APD should be considered as a differential diagnosis when multiple cutaneous FDG accumulations are found in a patient on hemodialysis. To the best of our knowledge, this is the first report showing the FDG PET/CT findings of APD.

Endoscopic full-thickness resection of gastric subepithelial tumors with a full-thickness suturing device has been described as feasible in two small case series. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this resection technique. After 31 patients underwent endoscopic full-thickness resection, the data were analyzed retrospectively. Before snare resection, 1 to 3 full-thickness sutures were placed underneath each tumor with a device originally designed for endoscopic anti-reflux therapy. All tumors were resected successfully. Bleeding occurred in 12 patients (38.7 %); endoscopic hemostasis could be achieved in all cases. Perforation occurred in 3 patients (9.6 %), and all perforations could be managed endoscopically. Complete resection was histologically confirmed in 28 of 31 patients (90.3 %). Mean follow-up was 213 days (range, 1 - 1737), and no tumor recurrences were observed. Endoscopic full-thickness resection of gastric subepithelial tumors with the suturing technique described above is feasible and effective. After the resection of gastrointestinal stromal tumors (GISTs), we did not observe any recurrences during follow-up, indicating that endoscopic full-thickness resection may be an alternative to surgical resection for selected patients. © Georg Thieme Verlag KG Stuttgart · New York.

Risk of upper gastrointestinal bleeding and perforation associated with low-dose aspirin as plain and enteric-coated formulations

de Abajo, Francisco J; García Rodríguez, Luis A

2001-01-01

Background The use of low-dose aspirin has been reported to be associated with an increased risk of upper gastrointestinal complications (UGIC). The coating of aspirin has been proposed as an approach to reduce such a risk. To test this hypothesis, we carried out a population based case-control study. Methods We identified incident cases of UGIC (bleeding or perforation) aged 40 to 79 years between April 1993 to October 1998 registered in the General Practice Research Database. Controls were selected randomly from the source population. Adjusted estimates of relative risk (RR) associated with current use of aspirin as compared to non use were computed using unconditional logistic regression. Results We identified 2,105 cases of UGIC and selected 11,500 controls. Among them, 287 (13.6%) cases and 837 (7.3%) controls were exposed to aspirin, resulting in an adjusted RR of 2.0 (1.7-2.3). No clear dose-effect was found within the range of 75-300 mg. The RR associated with enteric-coated formulations (2.3, 1.6-3.2) was similar to the one of plain aspirin (1.9, 1.6-2.3), and no difference was observed depending on the site. The first two months of treatment was the period of greater risk (RR= 4.5, 2.9-7.1). The concomitant use of aspirin with high-dose NSAIDs greatly increased the risk of UGIC (13.3, 8.5-20.9) while no interaction was apparent with low-medium doses (2.2, 1.0-4.6). Conclusions Low-dose aspirin increases by twofold the risk of UGIC in the general population and its coating does not modify the effect. Concomitant use of low-dose aspirin and NSAIDs at high doses put patients at a specially high risk of UGIC. PMID:11228592

Observational cohort study. To compare the rate of pedicle perforation while inserting screws (PS) using O-arm navigation during surgery for scoliosis with that reported previously, and to determine risk factors specific to O-arm navigation. O-arm navigation provides intraoperative three-dimensional fluoroscopic imaging with an image quality similar to that of computed tomography. Surgeons have started using O-arm navigation in treatment of adolescent idiopathic sclerosis (AIS). However, there are few reports of the perforation rate when using O-arm navigation to insert pedicle screws for AIS. To our knowledge, no information has been published regarding risk factors for pedicle perforation by PS when using O-arm navigation during surgery for AIS. We retrospectively reviewed the cases of 23 consecutive patients with AIS (all female; mean age 15.4 years, range 12-19 years) who had all undergone PS fixation under O-arm navigation. There were 11 major pedicle perforations (Grade 2 or 3) by the 404 screws (2.7%). For both Grade 1-3 and Grade 2 or 3 perforations, the pedicle perforation rate by the ninth or subsequent screws was significantly higher than that for the other two groups (screws 1-4, 5-8) (P < 0.01). Grade 1-3, Grades 2 or 3, and Grade 3 perforation rates after a previous perforation were significantly higher than those in patients without a previous perforation (P < 0.01). The rate of screw deviation can increase significantly to 12.2% after insertion of 8. The rate of major perforation of pedicles after inserting PS using O-arm navigation during surgery for AIS is relatively low. However, we recommend caution using intraoperative navigation after inserting 8 pedicle screws because after this, the trajectory deviation rate can increase significantly. 3.

A perforated peptic ulcer can be managed laparoscopically in selected patients. The purpose of this study was to evaluate whether conversion of emergency laparoscopy is inferior to primary median laparotomy in terms of postoperative morbidity and mortality. We analyzed patients who underwent laparoscopic or open surgery for a perforated peptic ulcer at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck between January, 1996 and December, 2010. Perforations were graded according to the Boey classification, a preoperative risk-scoring system. Conversion to laparotomy was necessary in 20 of the 45 patients who underwent laparoscopic surgery (CG); therefore, laparoscopic operations were completed in 25 patients (LG). The third patient cohort comprised 139 patients who underwent primary laparotomy (OG). Overall minor morbidity was significantly lower (p = 0.048) in the LG patients than in the OG patients, whereas no significant differences were found in major morbidity and mortality, particularly between the OG and CG. Patients' suitability for laparoscopic management should be decided on according to Boey's clinical scoring system. Our findings demonstrated that conversion from laparoscopy to laparotomy was not associated with elevated postoperative morbidity or mortality versus initial laparotomy. Therefore, emergency operations may be commenced laparoscopically in selected patients, especially considering the postoperative advantages of this approach.

Appendicitis is the most common indication for emergency pediatric surgery and its most significant complication is perforation. Perforated appendicitis (PA) may be managed conservatively, whereas non-perforated appendicitis (NP) is managed surgically. Recent studies have shown that ultrasound (US) is effective for differentiating between PA and NP, and does not expose pediatric patients to ionizing radiation. The purpose of this study is to enhance the accuracy of differentiation with a novel scoring system based on clinical, laboratory, and US findings. This retrospective study included 243 patients aged 2-17 years who presented between 2006 and 2013 with surgically proven appendicitis, of whom 60 had perforation. Clinical and laboratory data were collected and US images evaluated by a pediatric radiologist. To create the scoring system, point values were assigned to each parameter. A randomly selected training sample of 137 subjects was used to create a scoring prediction model. The model was tested on the remaining 106 patients. Scores of ≥6, ≥11, and ≥15 yielded specificities of 64, 91, and 99%, and sensitivities of 96, 61, and 29%, respectively (p < 0.001). We have designed a scoring system incorporating clinical, laboratory, and sonographic findings which can differentiate PA from NP with high specificity.

Necrotizing enterocolitis, a rare but severe condition with insidious postoperative complications.

Necrotizing enterocolitis (NEC) is one of the most frequent causes of gastrointestinal perforation in premature neonates, only few case series and reports being described in adult patients. Early in the course of the disease, superficial mucosal ulceration, sub mucosal edema and hemorrhage occur. Further progression leads to transmural necrosis leading sometimes to bowel perforation. Six cases encountered in our clinic in recent years led us to resume discussions on necrotizing enteritis, not because it is a rare disease, but due to the severe postoperative complications. Our lot consisted of four stage 1 patients and two with Bell stage III NEC and severe intestinal injury, necrosis, and perforation. All of the patients were diagnosed preoperatory with other surgical conditions, like appendicitis with peritonitis, perforated duodenal ulcer or acute cholecystitis. We present to review two cases. For patients undergoing laparotomy, resection of the involved intestine mandates either enterostomy formation or primary anastomosis. An intermediate option is laparotomy with intestinal resection and delayed anastomosis 48 to 72 hours later. Because of the small number of patients in our lot, we cannot advise a certain surgical treatment, but a strategy involving bienterostomyper primam should be further analyzed. The choice of operative intervention reflects multiple variables, including age, physiologic status, institutional resources and surgeon preference based on experience. Primary peritoneal drainage for perforated NEC may help to resuscitate and treat a critically ill patient initially, and in some instances, may be definitive operative intervention. Relatively rare disease, of unknown etiology and elusive pathogenesis, NEC has initial non-specific symptoms and clinical features that mimic more common surgical diseases. There is considerable controversy regarding which procedure is preferable. Currently, in the absence of rigorous evidence supporting the superiority of one approach over the other, surgical intervention depends mostly on the treating institution or the individual surgeon.

The purpose of this study was to describe the indications for and technique of transjugular renal biopsy (TJRB) and evaluate the efficacy and complications of this method. We performed a retrospective review of 59 patients who underwent TJRB using the Quick-core needle biopsy system (Cook, Letchworth, UK) over a 4-year period. The indications for obtaining renal biopsy included acute renal failure, chronic renal failure, nephrotic syndrome, and proteinuria with or without other associated disease. Indications for the transjugular approach included coagulopathy, biopsy of a solitary kidney or essentially single functioning kidney, simultaneous renal and hepatic biopsy, morbid obesity, and failedmore » percutaneous biopsy. All but four cases were performed via the right internal jugular vein. The right, left, or both renal veins were cannulated in 41, 14, and 4 cases, respectively. Combined liver and renal biopsies were obtained in seven cases. Diagnostic biopsy specimens were obtained in 56 of 59 patients (95%). The number and size of tissue cores ranged from 1 to 9 mm and from 1 to 20 mm, respectively. The mean numbers of glomeruli per procedure on light microscopy and electron microscopy were 10.3 and 2.6, respectively. Specimens for immunohistology were acquired in 49 cases, of which 40 were adequate. Of the 56 successful TJRB procedures, 34 (61%) were associated with isolated capsular perforation (19), contained subcapsular leak (10), isolated collecting system puncture (1), and concurrent collecting system and capsular perforation (4). There was a significant increase in capsular perforation with six or more needle passes, although no significant correlation was seen between number of needle passes and complication. Six patients had minor complications defined as hematuria or loin pain. Seven patients developed major complications, of whom five received blood transfusion alone. Two required intervention: in one an arteriocalyceal fistula was embolized and the patient was temporarily dialyzed; the remaining patient required ureteric stenting. In conclusion, TJRB provides an adequate yield for diagnosis. Complication rates are relatively high, but patients are also at high risk from the conventional percutaneous approach. Patient selection and optimization are critical to avoid major complications.« less

Selective targeting of diseased cells can increase therapeutic efficacy and limit off-target adverse effects. We developed a new tool to selectively perforate living cells with functionalized gold nanoparticles (AuNPs) and near-infrared (NIR) femtosecond (fs) laser. The receptor CD44 strongly expressed by cancer stem cells was used as a model for selective targeting. Citrate-capped AuNPs (100 nm in diameter) functionalized with 0.01 orthopyridyl-disulfide-poly(ethylene glycol) (5 kDa)-N-hydroxysuccinimide (OPSS-PEG-NHS) conjugated to monoclonal antibodies per nm2 and 5 μM HS-PEG (5 kDa) were colloidally stable in cell culture medium containing serum proteins. These AuNPs attached mostly as single particles 115 times more to targeted CD44+ MDA-MB-231 and CD44+ ARPE-19 cells than to non-targeted CD44- 661W cells. Optimally functionalized AuNPs enhanced the fs laser (800 nm, 80-100 mJ cm-2 at 250 Hz or 60-80 mJ cm-2 at 500 Hz) to selectively perforate targeted cells without affecting surrounding non-targeted cells in co-culture. This novel highly versatile treatment paradigm can be adapted to target and perforate other cell populations by adapting to desired biomarkers. Since living biological tissues absorb energy very weakly in the NIR range, the developed non-invasive tool may provide a safe, cost-effective clinically relevant approach to ablate pathologically deregulated cells and limit complications associated with surgical interventions.Selective targeting of diseased cells can increase therapeutic efficacy and limit off-target adverse effects.

Perforator flaps have been successfully used for reconstruction of pressure sores. Although V-Y advancement flaps approximate debrided wound edges, perforator-based propeller flaps allow rotation of healthy tissue into the defect. Perforator-based propeller flaps were planned in 13 patients. Seven pressure sores were over the sacrum, five over the ischial tuberosity, and one on the tip of the scapula. Three patients were paraplegic, six were bedridden, and five were ambulatory. In three patients, no perforators were found. In 10 patients, propeller flaps were transferred. In two patients, total flap necrosis occurred, which was reconstructed with local advancement flaps. In two cases, a wound dehiscence occurred and had to be revised. One hematoma required evacuation. No further complications were noted. No recurrence at the flap site occurred. Local perforator flaps allow closure of pressure sores without harvesting muscle. The propeller version has the added benefit of transferring tissue from a distant site, avoiding reapproximation of original wound edges. Twisting of the pedicle may cause torsion and venous obstruction. This can be avoided by dissecting a pedicle of at least 3 cm. Propeller flaps are a safe option for soft tissue reconstruction of pressure sores. © Thieme Medical Publishers.

Peptic ulcer perforation is a serious complication of peptic ulcer disease with a significant morbidity and mortality. To evaluate 76 patients operated for peptic ulcer perforation and analyse the associated factors in Zewditu Memorial Hospital, Addis Ababa from September 2006 to August 2008. A retrospective analysis of medical records of 76 patients who were operated up on for perforated peptic ulcer over a two year period (2006-2008). The male to female ratio was 6.6:1 with a mean age being 31.5 years. The most common presenting symptom was abdominal pain in 76 (100%) patients. History of smoking and khat chewing was documented in 53/64 (82.8%) and 48/64 (75%) of the patients respectively. Twenty five per cent of the patients gave no history of previous peptic ulcer disease. Seventy patients (92.1%) presented after 48 hours of their illness. The mean hospital stay was 14.5 days. Leucocytosis was found in 31.6% of the cases. Sixty five (85.5%) patients had duodenal ulcer perforation. Postoperative complications occurred in 24 (31.6%) patients. Twelve (15.8%) patients died in the hospital. Early presentation of patients and change in life style may reduce morbidity and mortality in patients with peptic ulcer perforation.

The propeller flap is defined as (1) being island-shaped, (2) having an axis that includes the perforators, and (3) having the ability to be rotated around an axis. The advantage of the propeller flap is that it is a pedicle flap that can be applied to cover defects located at the distal ends of the extremities. The specific aims of the authors' study were (1) to evaluate the usefulness of multidetector-row computed tomography in the planning of propeller flaps and (2) to present a clinical case series of propeller flap reconstructions that were planned preoperatively using multidetector-row computed tomography. The authors retrospectively analyzed all cases between April of 2007 and April of 2010 at Nippon Medical School Hospital in Tokyo, where multidetector-row computed tomography was used preoperatively to plan surgical reconstructions using propeller flaps. Thirteen patients underwent 16 flaps using the propeller flap technique. The perforators were identified accurately by multidetector-row computed tomography preoperatively in all cases. This is the first report describing the application of multidetector-row computed tomography in the planning of propeller flaps. Multidetector-row computed tomography is superior to other imaging methods because it demonstrates more precisely the perforator's position and subcutaneous course using high-resolution three-dimensional images. By using multidetector-row computed tomography to preoperatively identify a flap's perforators, the surgeon can better plan the flap design to efficiently conduct the flap surgery.

Coronary perforation (CP) during chronic total occlusion percutaneous coronary intervention for stable angina (CTO-PCI) is a rare but serious event. The evidence base is limited, and the long-term effects are unclear. Using a national PCI database, the incidence, predictors, and outcomes of CP during CTO-PCI were defined. Data analyzed from the British Cardiovascular Intervention Society data set on all CTO-PCI procedures performed in England and Wales between 2006 and 2013. Multivariate logistic regressions and propensity scores were used to identify predictors of CP and its association with outcomes. A total of 376 CP were recorded from 26 807 CTO-PCI interventions (incidence of 1.40%) with an increase in frequency during the study period ( P =0.012). Patient-related factors associated with an increased risk of CP were age and female sex. Procedural factors indicative of complex CTO intervention strongly related to an increased risk of CP with a close relationship between the number of complex strategies used and CP evident ( P =0.008 for trend). Tamponade occurred in 16.6% and emergency surgery in 3.4% of cases. Adverse outcomes were frequent in those patients with perforation including bleeding, transfusion, myocardial infarction, and death. A legacy effect of perforation on mortality was evident, with an odds ratio for 12-month mortality of 1.60 for perforation survivors compared with matched nonperforation survivors without a CP ( P <0.0001). Many of the factors associated with an increased risk of CP were related to CTO complexity. Perforation was associated with adverse outcomes, with a legacy effect on later mortality after CP also observed. © 2017 American Heart Association, Inc.

A Novel Tectonic Keratoplasty with Femtosecond Laser Intrastromal Lenticule for Corneal Ulcer and Perforation

PubMed Central

Jiang, Yang; Li, Ying; Liu, Xiao-Wei; Xu, Jing

2016-01-01

Background: Small incision refractive lenticule extraction (SMILE) is an effective laser procedure that treats myopia. This research was to describe a novel approach to treat corneal ulcer or perforation using the corneal lenticules obtained from SMILE and to evaluate the safety and effectiveness of tectonic keratoplasty with femtosecond laser intrastromal lenticule (TEKIL). Methods: A total of twenty patients (22 eyes) were monitored for at least 6 months and were assessed using slit lamp microscopy, optical coherence tomography, and best-corrected visual acuity (BCVA). Postoperative complications throughout the study period were recorded. Results: Corneal ulcer in 14 patients (16 eyes) and corneal perforation in six patients (6 eyes) were treated with TEKIL. The patients were ten females and ten males, with a mean age of 58.5 ± 16.3 years (range: 16–81 years). In this study, the most causes of corneal ulcer or perforation were immunologic causes (54.5%). After TEKIL procedure, global integrity was achieved in all cases. No immune rejection or perforation was detected. The mean BCVA improved from 0.17 ± 0.20 preoperatively to 0.27 ± 0.25 postoperatively at the final follow-up (t = 2.095, P = 0.052). The postoperative BCVA improved in 12 eyes (54.5%) and maintained in nine eyes (40.9%). Vision function successfully maintained in all eyes (100%). In three cases, corneal ulcers were treated by reoperation of TEKIL at 3 months after the initial surgery for the reason that the residual corneal thickness was <250 μm. Conclusions: TEKIL seems to be an effective treatment for corneal ulcer and perforation in the condition of emergency and donor shortage. PMID:27453231

Purpose . Anterior screw fixation has become a popular surgical treatment method for instable odontoid fractures. Screw loosening and migration are a rare, severe complication following anterior odontoid fixation, which can lead to esophagus perforation and requires revision operation. Methods . We report a case of screw loosening and migration after anterior odontoid fixation, which perforated the esophagus and was excreted without complications in a 78-year-old male patient. Results . A ventral dislocated anterior screw perforated through the esophagus after eight years after implantation and was excreted through the gastrointestinal (GI) tract. At a 6-month follow-up after the event the patient was asymptomatic. Conclusion . Extrusion via the GI tract is not safe enough to be considered as a treatment option for loosened screws. Some improvements could be implemented to prevent such an incident. Furthermore, this case is a fine example that recent preoperative imaging is mandatory before revision surgery for screw loosening.

A case of duodenal perforation associated with aspirin ingestion in a 21-year old male Nigerian with sickle cell anaemia is reported. He presented with a sudden onset of epigastric pain which later spread to involve other parts of the abdomen. He had previously used aspirin at a dose of 1800 mg daily for two weeks to treat bone pain. Abdominal ultrasonography and X-ray showed fluid collection in the pelvis and elevation of the diaphragm. At exploratory laparotomy, the perforation found in the first part of the duodenum anteriorly was repaired. He was discharged 11 days post-surgery. In view of the frequent usage of salicylates and non-steroidal anti-inflammatory drugs to treat painful crises in sickle cell disease, we suggest careful monitoring of patients on such drugs and those with dyspeptic symptoms must be fully investigated including the use of endoscopy, to prevent fatal outcome.

Lymphoproliferative disorder (LPD) is a potentially severe adverse effect of methotrexate (MTX) administration in patients with rheumatoid arthritis (RA). We report a case of MTX-associated LPD (MTX-LPD) in a patient with RA who developed severe pulmonary failure complicated by perforation of the terminal ileum. A 61-year-old woman with RA receiving MTX complained of dyspnea and abdominal pain. She was diagnosed with intestinal perforation and peritonitis, and underwent immediate abdominal surgery. Pathological examinations of the specimen obtained from the resected ileum and a bone marrow aspirate revealed diffuse large B-cell lymphoma. Steroid therapy failed to improve her respiratory failure, but her condition improved after abdominal surgery and suspension of MTX. MTX-LPD can result in multiple life-threatening conditions; however, the symptoms are highly variable. RA patients receiving MTX should thus be monitored carefully, and MTX administration should be stopped immediately on suspicion of MTX-LPD.

Pure Motor Stroke Secondary to Cerebral Infarction of Recurrent Artery of Heubner after Mild Head Trauma: A Case Report.

The recurrent Heubner's artery is the distal part of the medial striate artery. Occlusion of the recurrent artery of Heubner, classically contralateral hemiparesis with fasciobrachiocrural predominance, is attributed to the occlusion of the recurrent artery of Heubner and is widely known as a stroke syndrome in adults. However, isolated occlusion of the deep perforating arteries following mild head trauma also occurs extremely rarely in childhood. Here we report the case of an 11-year-old boy with pure motor stroke. The brain MRI showed an acute ischemia in the recurrent artery of Heubner supply area following mild head trauma. His fasciobrachial hemiparesis and dysarthria were thought to be secondary to the stretching of deep perforating arteries leading to occlusion of the recurrent artery of Heubner. Post-traumatic pure motor ischemic stroke can be secondary to stretching of the deep perforating arteries especially in childhood.

Influenza virus infection is extremely common and raises global concern due to the increasing prevalence of pandemic H1N1 infection. Influenza may occasionally be associated with neurologic complications and, also, rarely with gastrointestinal complications. Here, we report a rare case complicated with appendicitis, duodenum perforation, and transient delirious behavior after influenza A viral infection in a pediatric patient aged 14 years. The transient delirious behavior could be attributed to postinfectious encephalopathy. The perforated peptic ulcer could have resulted from influenza infection, could have been an adverse event related to oseltamivir administration, or could have been a complication of preceding gastroenteritis. Our case highlights the importance of pediatric healthcare workers to be aware of possible complications arising from both influenza infection and oseltamivir therapy, even though some of these complications may be relatively rare.

Midurethral slings are an effective and minimally invasive treatment for stress urinary incontinence. One of the most common intraoperative complications is bladder perforation, complicating between 2 and 10% of all operations, and on average 4.7%. It is usually corrected during surgery, with repositioning of the trocars. The purpose of this video is to demonstrate a method of replacing the trocars under direct vision. This video exhibits a bladder perforation during insertion of a retropubic midurethral sling (Advantage Fit; Boston Scientific) and gives a step-by step guide to the removal and repositioning of the sling under direct visualisation. Repositioning of the trocars under direct vision in cases of bladder perforation may have numerous advantages. It may prevent damage to the urethra, possibly reduce the risk of postoperative infection and may be beneficial for trainees.

2015-01-01

Perforated duodenal ulcers are rare complications seen after roux-en-Y gastric bypass (RYGP). They often present as a diagnostic dilemma as they rarely present with pneumoperitoneum on radiologic evaluation. There is no consensus as to the pathophysiology of these ulcers; however expeditious treatment is necessary. We present two patients with perforated duodenal ulcers and a distant history of RYGP who were successfully treated. Their individual surgical management is discussed as well as a literature review. We conclude that, in patients who present with acute abdominal pain and a history of RYGB, perforated ulcer needs to be very high in the differential diagnosis even in the absence of pneumoperitoneum. In these patients an early surgical exploration is paramount to help diagnose and treat these patients.

A Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. It is a real diverticulum that is usually located on the anti-mesenteric edge in the last meter of the ileum. Its location on the mesenteric edge has been rarely reported. It may lead to several complications including perforation that may be life-threatening for the patient. We report herein a case of perforated mesenteric Meckel's diverticulum in an adult patient. Upon surgical exploration by laparotomy, we found a perforated Meckel's diverticulum located on the mesenteric edge of the ileum 60 cm from the ileocoecal junction and 400 ml of seropurulent peritoneal fluid. The patient underwent a segmental ileal resection and an end-to-end anastomosis. The postoperative outcomes were marked by a persistent peritonitis that required successful revision surgery.

Colonoscopy is widely used for the diagnosis, treatment and a follow up of colorectal diseases. Perforation of the large bowel during elective colonoscopy is rare but serious life threatening complication. We report a 51-year-old woman who experienced recto sigmoid perforation during diagnostic colonoscopy. During 8 days of total hospitalization, she spent 3 days in ICU with gastrointestinal rest. The patient was hydrated and took intravenous antibiotics. In take-output and temperature were closely monitored. Serial abdominal examinations were performed to rule out peritonitis. After transferring to surgery ward in the day 4, liquid diet started slowly, and she was ambulated. At the day 8, she was discharged with the good clinical condition. Conservative management of the patients with early diagnosis of perforation and no signs and symptoms of peritonitis or sepsis could be the modality of choice.

According to the Guidelines for Diagnosis and Treatment of Carcinoma of the Esophagus in Japan, the standard treatment of esophageal cancer with cStage II / III is preoperative chemotherapy and radical resection. But when the tumor has deep ulcer, the perforation of it is sometimes occurred due of the anti-tumor effect and we are forced to change the standard treatment. In this time, we report a case of emergency resection of esophageal cancer which is on the brink of perforation after neoadjuvant chemotherapy. A 62-year-old woman had locally advanced esophageal cancer(cT4N2M0)and performed neoadjuvant chemotherapy(NAC). After 2 courses of NAC, the patient got into critical condition that the esophageal cancer was on the brink of perforation, thus we immediately performed emergency resection of the tumor. Unfortunately, the tumor was not completely resected because of invasion to the Botallo ligament, but we were able to avoid a critical state such as mediastinitis or penetration to the aorta. In multimodality therapy for locally advanced tumor, immediate response to oncologic emergency is significantly required, impacting on the prognosis and quality of life.

Patients with a nasal septal perforation often exhibit symptoms associated with disturbed airflow, which can have an adverse effect on the warming function of the nasal cavity. The impact of this effect is not fully understood. The warming function is an important factor in the maintenance of nasal physiology. We conducted a study to investigate the impact of septal perforations of various sizes and locations on the warming function during inspiration in 5 patients-3 men and 2 women, aged 25 to 47 years. Three-dimensional computed tomography and computational fluid dynamics were used to model the flux of communication and temperature, and differences among patients were compared. All 5 patients exhibited an impairment of their nasal warming function. As the size of the perforation increased, the flux of communication increased and the warming function decreased. Perforations located in an anterior position were associated with greater damage to the warming function than those in a posterior position. In patients with a large or anteriorly located perforation, airflow temperature in the nasopharynx was decreased. Our findings suggest that septal perforations not only induce airflow disturbance, but they also impair the nasal warming function. Further analysis of warming function is necessary to better explore flow mechanisms in patients with structural abnormalities.

The major complications of peptic ulcer are hemorrhage, perforation and gastric outlet obstruction with perforation occurring in about 2-10% of patients. Patients with perforated peptic ulcer still have a high rate of morbidity and mortality and to improve the outcomes it is important to stratify the patients into different categories. To evaluate the accuracy of Boey scoring system in predicting postoperative morbidity and mortality in patients operated for peptic perforation. It was a prospective observational single centre study conducted at SMS Medical College and Hospital, Jaipur, from October 2011 to October 2012 on 180 patients undergoing open surgery for peptic ulcer perforation. Postoperative outcomes in terms of recovery and complications were studied. For prediction of morbidity and mortality by Boey risk stratification, the odds ratio (OR) and 95% confidence interval (95% CI) of each risk score were compared with the outcomes of "0" risk score. The mortality rate increased progressively with increasing numbers of the Boey score: 1.9%, 7.1%, 31.7% and 40% for 0, 1, 2, and 3 scores, respectively (p < 0.001). The morbidity rates for 0, 1, 2, and 3 Boey scores were 13%, 45.7%, 70.7% and 73.3% respectively (p < 0.001). Boey score is a useful tool for assessing the prognosis of operated cases of peptic perforation and helps in the assessment of mortality and morbidity of these patients.

Simultaneous non-traumatic perforation of the extrahepatic bile duct and the gallbladder is an uncommon occurrence that has been infrequently reported. We describe a patient with a spontaneous perforation of both the extrahepatic bile duct and the gallbladder. A contrast-enhanced computed tomography (CECT) scan of the abdomen and endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a perforation of the gallbladder and a free leak from the right hepatic duct, respectively. Endoscopic biliary drainage following a sphincterotomy and biliary stent placement led to a dramatic improvement in the patient's general condition. He was subsequently scheduled to undergo an elective cholecystectomy. Repeat ERCP performed at 4 weeks after the initial stenting showed a normal cholangiogram and a distally migrated stent, which was there after removed. However, early stent removal led to re-perforation of hepatic duct and gallbladder. A repeat endoscopic biliary drainage did not help, and the patient developed biliary peritonitis. Surgical exploration revealed a perforation at the fundus of the gallbladder, 400 ml of biliopurulent collection and a frozen Calot's triangle. A subtotal cholecystectomy, gall stone removal, and a thorough peritoneal lavage were undertaken. The patient improved postoperatively. The second biliary stent was removed after 4 months. This case report highlights the role of endoscopic biliary drainage in the management of an extrahepatic bile duct perforation and warns against the early removal of a biliary stent.

Non-Hodgkin Lymphomas (NHL) appear with the malign transformation of mature lymphocytes. Intestinal perforations are one of the most well-known complications of NHLs. In this review, a 29-year-old male patient who was diagnosed with NHL with gastrointestinal involvement that developed intestinal perforation after chemotherapy is presented. A 29-year-old male patient who received systemic chemotherapy in another healthcare center due to Major B-Cell Lymphoma was examined because he had stomachache after the treatment. The patient was urgently taken to operation. In the exploration, there were partly mass lesions in all small intestine segments. It was determined that one of the lesion was perforated. Small intestine resection was applied. The pathology report on resection material was reported as High Grade Major B-Cell Lymphoma. In the treatment of Lymphoma with intestinal B-Cells, there is no consensus because this disease is rarely observed. Perforation may appear as a complication of the chemotherapy. Depending on the steroids given to the patient, perforation may develop, and the clinical symptoms may be masked. It must be born in mind that there may be intestinal involvement in patients diagnosed with NHL, and intestinal perforation may develop due to chemotherapy. Copyright © 2017 The Authors.

Sonic instruments may reduce perforation rates of the schneiderian membrane during lateral window sinus augmentation procedures. This study compares the incidence of membrane perforations using a sonic handpiece with an oscillating diamond insert versus a turbine handpiece with a conventional rotary diamond stone during lateral window sinus augmentation procedures. A retrospective chart analysis identified all lateral window sinus augmentation procedures done during a defined period. Among these procedures, those performed with a sonic handpiece and an oscillating diamond insert (experimental) and those performed with a conventional turbine and rotary diamond stone (conventional) were selected for this study. Reported occurrences of sinus membrane perforations during preparation of the osteotomy and elevation of the sinus membrane, as well as postoperative complications, were recorded and compared between treatment groups. Ninety-three consecutive patients were identified for a total of 130 sinus augmentation procedures (51 conventional, 79 experimental). Schneiderian membrane perforations were noted during preparation of the lateral window osteotomy in 27.5% of the sinuses in the conventional group and 12.7% of sinuses in the experimental group. During membrane elevation, perforations were noted in 43.1% of the sinuses in the conventional group and 25.3% of sinuses in the experimental group. Both differences in perforation rates were statistically significant (p < .05). There was no statistically significant difference in postoperative complications. In this study, the use of a sonic instrument to prepare the lateral window osteotomy during sinus elevation procedures resulted in a reduced perforation rate of the Schneiderian membrane compared with the conventional turbine instrument. © 2013 Wiley Periodicals, Inc.

The reconstruction of the posterior trunk remains to be a challenge as defects can be extensive, with deep dead space, and fixation devices exposed. Our goal was to achieve a tension-free closure for complex defects on the posterior trunk. From August 2006 to May 2013, 18 cases were reconstructed with multiple flaps combining perforator(s) and local skin flaps. The reconstructions were performed using freestyle approach. Starting with propeller flap(s) in single or multilobed design and sequentially in conjunction with adjacent random pattern flaps such as fitting puzzle. All defects achieved tensionless primary closure. The final appearance resembled a jigsaw puzzle-like appearance. The average size of defect was 139.6 cm(2) (range, 36-345 cm(2)). A total of 26 perforator flaps were used in addition to 19 random pattern flaps for 18 cases. In all cases, a single perforator was used for each propeller flap. The defect and the donor site all achieved tension-free closure. The reconstruction was 100% successful without flap loss. One case of late infection was noted at 12 months after surgery. Using multiple lobe designed propeller flaps in conjunction with random pattern flaps in a freestyle approach, resembling putting a jigsaw puzzle together, we can achieve a tension-free closure by distributing the tension to multiple flaps, supplying sufficient volume to obliterate dead space, and have reliable vascularity as the flaps do not need to be oversized. This can be a viable approach to reconstruct extensive defects on the posterior trunk. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Because of the unique characteristics of its integument, the affirmation "replacing like with like" becomes more than evident in the reconstruction of defects of the ultraspecialized plantar skin. But, the paucity of local resources, and especially in the forefoot, transforms this attempt in a very challenging problem. Many techniques, including skin grafts and various types of flaps were used in the management of defects in the forefoot. We present a new useful flap in the reconstruction of skin defects in the forefoot, based on small perforator vessels originating either from the plantar metatarsal arteries or plantar common digital arteries. Starting with June 2011, this flap was performed, as plantar transposition perforator flap, plantar propeller flap, or plantar propeller perforator plus flap, in seven patients with ulcers over the plantar forefoot. During a follow-up of 7 to 17 months (mean, 9.8 months), the local evolution regarding flap integration, pain, relapse, sensitive recovery, donor site, and footwear quality was analyzed. We registered a 100% survival rate of the flaps, with delayed healing in only one case. The gait resumption was possible after 6 weeks in all cases. This new flap, based on small perforator vessels from the plantar metatarsal or common digital arteries, and which provides a good, stable, and sensory recovery, seems to be a promising method in the reconstruction of plantar skin defects over the metatarsal heads.

Cardiac tamponade caused by perforation is a rare but potentially lethal complication of central venous catheter (CVC) insertion. We herein report a case of cardiac perforation associated with the use of a soft J-tipped guide wire. Twenty minutes after the insertion of a CVC, the patient developed unexpected cardiac arrest. An autopsy revealed 400 mL of pericardial blood. The right ventricular wall was 1 mm thick with about 10 myocyte layers, which is one-third that of the normal heart. A histological analysis revealed widespread fatty infiltration of the right ventricular wall (right ventricular lipomatosis).

Blunt abdominal trauma can damage the intestinal vasculature and may occasionally lead to delayed intestinal perforation, associated with a combined rate of morbidity and mortality of 25%. The diagnosis of such complications is hindered by sedation in critical patients, however, and morbimortality in this population is therefore higher. We report the case of a man with multiple injuries admitted to the intensive care unit, where delayed perforations of the sigmoid colon and cecum were diagnosed. The management of blunt abdominal trauma is reviewed and the possible causes, diagnostic approaches, and treatment options for colon injuries are discussed.

Gastric perforation secondary to metastasis from breast cancer occurs infrequently. We present the case of a 72-year-old postmenopausal female patient with a known history of lobular carcinoma of the breast who presented to a district general hospital with a clinical diagnosis of an acute abdomen. Further contrast-enhanced CT scan demonstrated free gas and fluid in the abdomen. She underwent emergency exploratory laparotomy and onlay Graham's omentopexy patch due to 1×1 cm prepyloric gastric perforation. Final histopathology proved the presence of metastatic malignant cells in the breast origin. We discuss the issues involved in postoperative investigation and management. 2016 BMJ Publishing Group Ltd.

Generally, ingested foreign bodies are excreted from the digestive tract without any complications or morbidity. In adults, ingestion of foreign bodies frequently occurs in alcoholics and elderly individuals with dentures. The most commonly ingested foreign bodies are food stuffs or their parts, such as fish bones or fragments of bone and phytobezoars. Sharp foreign bodies like fish and chicken bones can lead to intestinal perforation and peritonitis. We report herein two cases, one of bowel perforation and another of anal impaction, both caused by ingested bone fragments. Complications due to ingested bone fragments are not common and preoperative diagnosis remains a challenge and therefore it must be considered in susceptible cases.

Multi-limb necrotizing fasciitis in a patient with rectal cancer

Necrotizing fasciitis is a devastating soft tissue infection affecting fascias and subcutaneous soft tissues. Literature reviews have identified several related risk factors, including malignancy, alcoholism, malnutrition, diabetes, male gender and old age. There are only scanty case reports in the literature describing its rare association with colorectal malignancy. All published cases are attributed to bowel perforation resulting in necrotizing fasciitis over the perineal region. Isolated upper or lower limb diseases are rarely identified. Simultaneous upper and lower limb infection in colorectal cancer patients has never been described in the literature. We report an unusual case of multi-limb necrotizing fasciitis in a patient with underlying non-perforated rectal carcinoma. PMID:16937546

Two sand intervals, Sand No. 3 and Sand No. 1, were independently tested during our program. Sand No. 3 was the deepeer zone and was tested first. A gamma ray--neutron log of these zones, and the intervals perforated, are shown. The gamma ray log run in 1968 showed Sand No. 1 to be a fairly uniform section with few shale breaks and our original plans were to perforate the entire interval. After obtaining the more recent GR log big shale breaks were shown to exist throughout the zone, so a smaller interval was selected. A net sand thickness of 48more » ft. was used for Sand No. 3 and 30 ft. for Sand No. 1. There was no data available to indicate whether these zones became thicker or thinner away from the wellbore; therefore, these values were used as net thickness in the reservoir calculations. The procedure used to perforate the two sands were different. Both were perforated with 0.33 inch jets at a density of 4 shots per foot; however, Sand No. 3 was perforated in two runs using a stand-off gun, whereas Sand No. 1 was perforated in one run using a centralized gun with the jet density being 4 shots per foot but oriented alternately at 180 degrees.« less

Viscous damping and spring force calculation of regularly perforated MEMS microstructures in the Stokes' approximation

2013-01-01

There are a number of applications for microstructure devices consisting of a regular pattern of perforations, and many of these utilize fluid damping. For the analysis of viscous damping and for calculating the spring force in some cases, it is possible to take advantage of the regular hole pattern by assuming periodicity. Here a model is developed to determine these quantities based on the solution of the Stokes' equations for the air flow. Viscous damping is directly related to thermal-mechanical noise. As a result, the design of perforated microstructures with minimal viscous damping is of real practical importance. A method is developed to calculate the damping coefficient in microstructures with periodic perforations. The result can be used to minimize squeeze film damping. Since micromachined devices have finite dimensions, the periodic model for the perforated microstructure has to be associated with the calculation of some frame (edge) corrections. Analysis of the edge corrections has also been performed. Results from analytical formulas and numerical simulations match very well with published measured data. PMID:24058267

Despite numerous therapeutic advances, the treatment of pressure sores remains a challenge. The increased use of perforator flaps enables surgeons to minimize donor-site morbidity by sparing the underlying muscle. In the presence of focal deep spaces, however, the inclusion of muscle would be beneficial. The goal of this study was to introduce a method for including a muscle patch at the periphery of a perforator-based island flap for coverage of sacral pressure sores. Between March 2010 and February 2015, 26 patients with stage IV sacral sores underwent perforator-based island flap reconstruction with a peripheral muscle patch. Patient characteristics, including sex, age, defect size, and postoperative complications, were recorded. All flaps survived without major complications. No flap necrosis was noted. The present study shows that a muscle patch incorporated into the periphery of a perforator-based flap can be transferred safely. This can be a good surgical option in cases where infection control or more volume is needed. Copyright © 2016 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

A 26-year-old Caucasian female with keratoconus presented with an acutely painful and red left eye. Visual acuity on presentation was 3/60. Slit lamp examination revealed localised Descemet's membrane break with iris partially plugging it. There was a bulging stromal cyst which would intermittently flatten and reform. The appearance when the cyst was flattened mimicked a full thickness corneal perforation. However, no obvious overlying epithelial defect was detected and an intermittent leakage through micro-perforations in the corneal epithelium was the probable cause of the variable appearance. The anterior chamber reformed and iris plug freed following an insertion of a bandage contact lens and taped eyelid. On follow-up, the Descement's membrane had healed with visual acuity improving to 6/18. Our case illustrates the importance of identifying corneal hydrops mimicking a full thickness perforation as conservative management has a greater chance of recovery.

The authors describe a fatal case of gastric perforation secondary to an ulcerated metastasis in a woman with undiagnosed breast cancer. The 48-year-old woman, with no significant medical history, presented with weight loss, persistent dyspepsia and pain in the epigastric and mesogastric region. She was treated by her primary care physician with proton-pump inhibitors and antispasmodics. The following day she was found dead at her home. External examination showed a tumefaction in the lateral region of her left breast, near the axilla. Autopsy revealed 1000 ml of turbid, light-brown peritoneal fluid in the abdominal cavity and a perforated gastric wall. Histological examination of the breast mass showed an infiltrating, poorly-differentiated breast carcinoma. Microscopical analysis of the stomach wall revealed a perforated metastatic gastric ulcer. Immunohistochemistry was required to confirm the neoplastic involvement of the stomach due to metastatic breast cancer.

The available operative procedures for perforated gastric ulcer are gastrectomy, ulcer excision and omental patch closure. This study analysed the outcome of these operative options in a single institution. Seventy-two patients (mean age 43 years, 62 males) with perforated gastric ulcers were managed by laparotomy. There were 34 lesser curve (incisural) and 38 antral ulcers. Partial gastrectomy was performed in 27 patients, ulcer excision in 27 and simple patch closure in 18. Two ulcers were malignant. The mortality rate was 18% (26% for gastrectomy, 19% for ulcer excision and 5% for patch closure). Shock on admission (p = 0.006) and Candida (p = 0.020) in the histological specimen were predictive of poor outcome. Hospital stay was similar in the 3 groups. Omental patch closure and ulcer excision are as effective as gastrectomy in the management of perforated gastric ulcer and merit consideration as first-line therapy in technically applicable cases.

We describe a case of perforated peptic ulcer (PPU) in a 9-month-old boy. Abdominal distension was the first clinical sign of PPU. Before he developed abdominal distension, the patient had suffered from an upper respiratory tract infection with fever for about 2 weeks, which was treated intermittently with ibuprofen. A plain abdominal radiograph revealed pneumoperitoneum with a football sign. At laparotomy, a 0.8-cm perforated hole was found over the prepyloric area. Simple closure with omental patching was performed after debridement of the perforation. Pathologic examination showed chronic peptic ulcer with Helicobacter pylori infection. The postoperative course and outcome were satisfactory. The stress of underlying disease, use of ibuprofen, blood type (A), and H. pylori infection might have contributed to the development of PPU in this patient. PPU in infancy is rare and has a high mortality rate; early recognition and prompt surgical intervention are key to successful management.

The incidence of colonic diverticular disease varies with national origin, cultural background and diet. The frequency of this disease increases with advancing age. Right-sided diverticular disease is uncommon and reported to occur in 1-2% of surgical specimens in European and American series. In contrast the disease is more prevalent and reported in 43-50% of specimens in Asian series. Various lines of evidence suggest this variation may represent hereditary differences. The aim of the study is to report all cases of right sided diverticular disease underwent surgical resection or identified during pathological examination of right hemicoloectomy specimens A retrospective review of all surgical specimens with right sided colonic diverticular disease selected from a larger database of all colonic diverticulosis and diverticulitis surgical specimen reported between January 1993 and December 2010 at the Pathology Department McMaster University Medical Centre Canada. The clinical and pathological features of these cases were reviewed The review identified 15 cases of right colon diverticulosis. The clinical diagnoses of these cases were appendicitis, diverticulitis or adenocarcinoma. Eight cases of single congenital perforated diverticuli were identified and seven cases were incidental multiple acquired diverticuli found in specimen resected for right side colonic carcinomas/large adenomas. Laparotomy or laparoscopic assisted haemicolectomies were done for all cases. Pathological examination showed caecal wall thickening with inflammation associated with perforated diverticuli. Histology confirmed true solitary diverticuli that exhibited in two cases thick walled vessels in the submucosa and muscular layer indicating vascular malformation/angiodysplasia. Acquired diverticuli tend to be multiple and are mostly seen in specimens resected for neoplastic right colon diseases. Single true diverticular disease of the right colon is usually of congenital type and affects younger age group and may be associated with angiodysplasia in some cases. Multiple false diverticuli are more seen in association with caecal carcinoma or large adenomas. These are usually asymptomatic and are more seen in older patients. However this study dose not reflects the true incidence of the disease in the general population.

Intrauterine devices (IUDs) are the most popular form of contraception used worldwide; however, IUD is not risk-free. IUD migrations, especially uterine perforations, were frequently occurred in patients. The aim of this study was to investigate the clinical characteristics and intraoperative findings in patients with migrated IUDs. 29 cases of uterine perforation associated with migrated IUDs and 69 control patients were followed between January 2008 to March 2015. Patients who used IUDs within first 6 months from the last delivery experienced a characteristically high rate of the perforation of the uterine wall. A significantly larger number of IUD insertion associated with uterine perforation were performed in rural hospitals or operated at a lower level health care system. There was no clear difference in the age and presented symptoms in patients between two groups. Majority of contraceptive intrauterine devices was the copper-releasing IUDs. Furthermore, patients who used V-shaped IUD showed significantly higher incidence of pelvic adhesions when compared with the users of O-shaped IUDs. Unique clinical characteristics of IUD migration were identified in patients with uterine perforation. Hysteroscopy and/or laparoscopy were the effective approaches to remove the migrated IUDs. Improving operating skills is required at the lower level of health care system.

Gastro-duodenal perforations are common and may complicate peptic ulcer disease. Management is often by surgical closure. To determine the patterns of presentation and mode of management of duodenal ulcer perforations. Retrospective review of patients with duodenal ulcer perforations seen at the Obafemi Awolowo University Teaching Hospital between June 2001 and July 2011. Patients' records were reviewed for demography, duration of disease, probable risk factors, type of surgery and complications. Data obtained was analyzed using SPSS 15.0. Forty- five patients were reviewed. There were 37 males (82.2%). Mean age was 39.7years (range 15-78years). There were 10 (22.6%) students and 8(17.8%) farmers. NSAIDs abuse (11), previous peptic ulcer disease (2), and no prior dyspeptic symptoms (20) constituted 24.4%, 4.4% and 44.4% respectively of cases. Seven (16%) patients presented less than 24 hours of onset of illness. Forty one perforations (91.1%) involved the first part of duodenum. Twenty two (49%) patients had Graham's omental patch. We had one (2.2%) failed repair and six (13.3%) mortalities. Late presentation of duodenal ulcer perforation is common with high mortality. Pragmatic surgical intervention with Graham's omentopexy with broad spectrum antibiotics is still commonly practiced.

Intestinal tuberculosis (TB) was recognized as the most common complication with a high frequency of active pulmonary TB during the TB epidemic period. However, intestinal TB has become a rare disease, and intestinal perforation due to intestinal TB is extremely rare. We herein report two cases of tuberculous intestinal perforation. A 41-year-old man was admitted to our hospital complaining of persistent cough and anorexia. He was in poor nutritional condition, and his body mass index (BMI) and prognostic nutrition index (PNI) were 13.4 and 36.4, respectively. He was diagnosed with pulmonary TB and received anti-TB therapy. On the 51st day of hospitalization, he developed intestinal perforation. Pathologically caseating epithelioid granulomas were noted at the ulcer lesion. A 61-year-old man was admitted to our hospital due to miliary TB caused by intestinal TB. He had taken oral immunosuppressive drugs and steroids for dermatomyositis over the previous eight years and had a poor nutritional condition, with a BMI of 13.4 and a PNI of 14.4. While receiving anti-TB therapy, he developed intestinal perforation on the 97th day of hospitalization. The patient's poor nutritional condition and immune reconstitution may have contributed to the intestinal perforation.

The gastrointestinal tract is the most common site for extranodal involvement by non-Hodgkin's lymphoma. However, primary appendiceal lymphomas presenting as perforated acute appendicitis are very rare: they occur in only 0.015% of all gastrointestinal lymphoma cases. The management of this condition is still controversial, and a multimodality approach (e.g., surgery, radiation therapy, and chemotherapy) is the optimal treatment. In these cases, appendiceal non-Hodgkin's lymphomas typically manifest with acute symptoms in patients with no prior lymphoma history. Additionally, we treated our patient with a right hemicolectomy and postoperative multiagent chemotherapy.

The mini-sling procedure is a widely used, minimally invasive treatment for stress urinary incontinence. While bladder perforation and stone formation over the mesh is not an expected complication of the mini-sling procedure, in this case, we report on the management of bladder calculi formed over the mesh, which was passed through the bladder while applying the mini-sling procedure, and was eventually removed using holmium laser. Performing cystoscopy in patients with irritative and obstructive symptoms after the sling procedure will help confirm bladder perforation, and an endoscopic approach using holmium laser is an effective treatment.

Hyperkalemia is a common condition encountered in medical and surgical patients. It can lead to various complications including cardiac arrhythmias. Sodium polystyrene sulfonate (SPS) in sorbitol is an ion-exchange resin that can be used to treat hyperkalemia. It can be used in enema or in oral form. The present article describes the case of an intensive care unit patient who experienced severe, diffuse, intestinal perforation induced by the use of SPS-sorbitol, requiring multiple laparotomies, followed by a brief review of the relevant literature and recommendations regarding the use of SPS-sorbitol.

2015-09-26

Perforated peptic ulcer is a common emergency condition worldwide, with associated mortality rates of up to 30%. A scarcity of high-quality studies about the condition limits the knowledge base for clinical decision making, but a few published randomised trials are available. Although Helicobacter pylori and use of non-steroidal anti-inflammatory drugs are common causes, demographic differences in age, sex, perforation location, and underlying causes exist between countries, and mortality rates also vary. Clinical prediction rules are used, but accuracy varies with study population. Early surgery, either by laparoscopic or open repair, and proper sepsis management are essential for good outcome. Selected patients can be managed non-operatively or with novel endoscopic approaches, but validation of such methods in trials is needed. Quality of care, sepsis care bundles, and postoperative monitoring need further assessment. Adequate trials with low risk of bias are urgently needed to provide better evidence. We summarise the evidence for perforated peptic ulcer management and identify directions for future clinical research. Copyright © 2015 Elsevier Ltd. All rights reserved.

Acute otitis media with spontaneous tympanic membrane perforation.

PubMed

Principi, N; Marchisio, P; Rosazza, C; Sciarrabba, C S; Esposito, S

2017-01-01

The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

Mandibular reconstruction performed after virtual planning has become more common during recent years. The gold standard for extensive mandibular reconstruction is of course a fibular free flap. In designing an osteomyocutaneous fibula flap, poor planning, aberrant anatomy and/or inadequate perforator vessels are the most frequent causes of complications and may force the surgeon to modify the flap design, explore the contralateral leg or harvest an additional microvascular flap. The goal of our study was to pre-operatively evaluate the vascular anatomy of the fibula and localize the cutaneous perforator vessels, so to create the fibular cutting guide based on the position of the cutaneous perforator and safely harvest the reconstructive flap. Twenty consecutive patients who were candidates for mandibular reconstruction using a fibular microvascular free flap were enrolled in this study between January 2016 and August 2016. The patients were preoperatively assessed with a Computed Tomographic scan of head and neck and with a Computed Tomographic Angiography (CTA) scan of the lower limbs to evaluate the vascular anatomy of the fibula. Virtual planning was carried out for all patients. The fibular cutting guide was based on the position of the perforator cutaneous vessels, which were used to harvest the cutaneous part of the flap. Preoperative CT measurements were performed in order to identify the cutaneous perforators on the patients' skin. Intraoperative checking was performed to evaluate the accuracy of the perforators' position and the reproducibility of the virtual planning. In 5 patients out of 20 (25%), anatomical anomalies were discovered, without clinical evidence. The perforator vessels were localized in all patients. The average difference between the CTA and the intraoperative perforator localization was 1 mm (range 0-2 mm). Fibular cutting guide was positioned and fitted the anatomy of the patients in all treated patients. This allowed us to perform the planned segmentation of the fibula, obtaining the correct number of segments. In all cases, flap insetting was carried out and skin paddle was positioned as preoperatively planned. Neither donor site complications nor flap complications occurred. Preoperative evaluation of the legs using CTA, in patients who undergo an osteomyocutaneous fibular free flap for mandibular reconstruction, is a valuable approach to reduce altered-anatomy related complications and to improve the accuracy and outcomes of the reconstruction, especially in reconstructions of complex defects. In these cases, a soft tissue-based cutting guide can be planned based on the perforator vessels of the skin paddle, minimizing the harvesting risks of vascular lesions. Further studies and longer follow-ups are needed to evaluate the long-term outcomes and advantages of this procedure. Copyright © 2017 European Association for Cranio-Maxillo-Facial Surgery.

Safely combining abdominoplasty with aggressive abdominal liposuction based on perforator vessels: technique and a review of 300 consecutive cases.

PubMed

Smith, Lane F; Smith, Lane F

2015-05-01

There continues to be controversy about performing abdominoplasty concurrently with abdominal liposuction. The concern is that liposuction on the already vascularly compromised abdominal flap will lead to increased complications and flap necrosis. The central abdomen is supplied by the epigastric system. If perforator vessels from this system are spared, the blood supply to the abdomen can be spared and liposuction should be able to be safely performed on the elevated abdominal flap. The purpose of this study was to evaluate the safety of abdominoplasty with concurrent abdominal liposuction when a perforator vessel is spared. A standard abdominoplasty was performed, sparing one or two perforator vessels from the deep superior epigastric artery system. A retrospective chart review of 300 consecutive patients who underwent abdominoplasty surgery combined with concurrent abdominal liposuction was performed. Complications, total volume of abdominal liposuction, and results were reviewed. The overall complication rate was 17.3 percent (52 patients). Sixteen percent (48 patients) suffered minor complications and 1.3 percent (four patients) suffered major complications. Abdominoplasty can be combined safely with concurrent abdominal liposuction when a perforator vessel is spared. The combination of concurrent liposuction with abdominoplasty showed no increase in complication rates when a perforator vessel was spared. The perforator vessels are located consistently in a 2-cm radius located 4 cm from the midline and 6 cm from the subcostal margin. The potential advantages of abdominoplasty with concurrent liposuction include a better postoperative cosmetic result. Therapeutic, IV.

There is controversy regarding whether children with perforated appendicitis should receive early appendectomy (EA) versus medical management (MM) with antibiotics and delayed interval appendectomy. The objective of this study was to compare outcomes of children with perforated appendicitis who receive EA versus MM. Case review of consecutive children <18 years of age with perforated appendicitis who received either EA or MM during an 8-year period. Criteria for hospital discharge included patient being afebrile for at least 24 hours, pain-free and able to tolerate oral intake. Of 203 patients diagnosed with perforated appendicitis, 122 received EA and 81 received MM. All received parenteral antibiotic therapy initiated in the emergency department and continued during hospitalization. There were no significant differences between groups in mean patient age, mean complete blood count total white blood cells count, gender distribution, rates of emergency department fever or rates of intra-abdominal infection (abscess or phlegmon) identified on admission. Compared with patients receiving MM, those receiving EA experienced significantly fewer (1) days of hospitalization, parenteral antibiotic therapy and in-hospital fever; (2) radiographic studies, percutaneous drainage procedures and placement of central venous catheters performed; (3) post admission intra-abdominal complications and (4) unscheduled repeat hospitalizations after hospital discharge. Only 1 EA-managed patient developed a postoperative wound infection. Children with perforated appendicitis who receive EA experience significantly less morbidity and complications versus those receiving MM. The theoretical concern for enhanced morbidity associated with EA management of perforated appendicitis is not supported by our analysis.

Therapeutic management of perforated gastro-duodenal ulcer: literature review.

2013-11-01

Management of perforated gastro-duodenal ulcer (GDU) is not consensual, from no operative treatment to surgery by simple closure, gastrectomy and vagotomy. The purpose of this study is to report results of the literature concerning management of perforated GDU. Two authors, identified in the databases Pubmed and Embase studies, related to the therapeutic management of perforated GDU. The data were extracted from articles published between 1940 and 2012. Non-operative treatment is feasible for patients in good general condition and in good local circumstances without evolved peritonitis with a success rate more than 50%. Simple closure is the standard method. Laparoscopy is a safe and feasible method for patient with delay of treatment less than 24 hours and without associated complications with a success (meaning non conversion) of 80% and a mortality less than 1%. Rate of conversion is 7.9%, and increases in case of ulcer size >6 mm, frail ulcer edges, bleeding associated, unusual location and septic shock. Helicobacter pylori eradication is essential. Gastric tube, abdominal irrigation and drainage are still debated. Two-stage treatment for perforated gastric carcinoma, which represents 10 to 16% of gastric perforation, is a good option for frail patients with resectable tumors. Management of perforated GDU is still a subject of debate without guidelines but with several possibilities of treatment depending of local circumstances of peritonitis and size of defect >20 mm, general conditions, surgeon patterns and experience.

Objective To compare topical natamycin vs voriconazole in the treatment of filamentous fungal keratitis. Methods This phase 3, double-masked, multicenter trial was designed to randomize 368 patients to voriconazole (1%) or natamycin (5%), applied topically every hour while awake until reepithelialization, then 4 times daily for at least 3 weeks. Eligibility included smear-positive filamentous fungal ulcer and visual acuity of 20/40 to 20/400. Main Outcome Measures The primary outcome was best spectacle-corrected visual acuity at 3 months; secondary outcomes included corneal perforation and/or therapeutic penetrating keratoplasty. Results A total of 940 patients were screened and 323 were enrolled. Causative organisms included Fusarium (128 patients [40%]), Aspergillus (54 patients [17%]), and other filamentous fungi (141 patients [43%]). Natamycin-treated cases had significantly better 3-month best spectacle-corrected visual acuity than voriconazole-treated cases (regression coefficient=−0.18 logMAR; 95% CI, −0.30 to −0.05; P=.006). Natamycin-treated cases were less likely to have perforation or require therapeutic penetrating keratoplasty (odds ratio=0.42; 95% CI, 0.22 to 0.80; P=.009). Fusarium cases fared better with natamycin than with voriconazole (regression coefficient=−0.41 logMAR; 95% CI, −0.61 to −0.20; P<.001; odds ratio for perforation=0.06; 95% CI, 0.01 to 0.28; P<.001), while non-Fusarium cases fared similarly (regression coefficient=−0.02 logMAR; 95% CI, −0.17 to 0.13; P=.81; odds ratio for perforation=1.08; 95% CI, 0.48 to 2.43; P=.86). Conclusions Natamycin treatment was associated with significantly better clinical and microbiological outcomes than voriconazole treatment for smear-positive filamentous fungal keratitis, with much of the difference attributable to improved results in Fusarium cases. Application to Clinical Practice Voriconazole should not be used as monotherapy in filamentous keratitis. Trial Registration clinicaltrials.gov Identifier: NCT00996736 PMID:23710492

The method of free-hand pedicle screw placement is generally safe although it carries potential risks. For this reason, several highly accurate computer-assisted systems were developed and are currently on the market. However, these devices have certain disadvantages. We have developed a method of pedicle screw placement in the lumbar and sacral region using a multi-level drill guide template, created with the rapid prototyping technology and have validated it in a clinical study. The aim of the study was to manufacture and evaluate the accuracy of a multi-level drill guide template for lumbar and first sacral pedicle screw placement and to compare it with the free-hand technique under fluoroscopy supervision. In 2011 and 2012, a randomized clinical trial was performed on 20 patients. 54 screws were implanted in the trial group using templates and 54 in the control group using the fluoroscopy-supervised free-hand technique. Furthermore, applicability for the first sacral level was tested. Preoperative CT-scans were taken and templates were designed using the selective laser sintering method. Postoperative evaluation and statistical analysis of pedicle violation, displacement, screw length and deviation were performed for both groups. The incidence of cortex perforation was significantly reduced in the template group; likewise, the deviation and displacement level of screws in the sagittal plane. In both groups there was no significantly important difference in deviation and displacement level in the transversal plane as not in pedicle screw length. The results for the first sacral level resembled the main investigated group. The method significantly lowers the incidence of cortex perforation and is therefore potentially applicable in clinical practice, especially in some selected cases. The applied method, however, carries a potential for errors during manufacturing and practical usage and therefore still requires further improvements.

Perforator flaps are thin free-tissue transfers consisting of skin and subcutaneous tissue which have the advantage of decreasing donor site morbidity. We have reconstructed postburn scar contractures using "propeller flaps" of the remaining healthy skin around the recipient sites. In this paper, we report on two cases and describe the concept of using "perforator flaps" and "propeller flaps" together as what are called "perforator pedicled propeller (PPP) flaps." Patient 1 was an 18-year-old man with a sacral pressure ulcer. The soft tissue defect was reconstructed with a rotated superior gluteal artery PPP flap. Patient 2 was a 53-year-old woman who presented with an open fracture of the right elbow. The skin defect over the fracture was covered with a rotated deep brachial artery PPP flap raised on the lateral upper arm. The PPP flaps are useful for burn reconstruction and repairing various types of wound. Moreover, microsurgery is unnecessary. The PPP flap may be classified into two types: the central axis type and the acentric axis type. The central axis PPP flap is significant when used as a 90-degree-rotation island flap, and the acentric axis PPP flap is significant when used as a 180-degree-rotation island flap. Both types are easy to harvest and useful for repairing various kinds of wound.

To evaluate the oncologic safety of colonic self-expandable metal stents (SEMS) in obstructive colon cancer. We retrospectively reviewed all the patients who were treated with endoscopic placement of a self-expandable metallic stent (SEMS) at our institution. A total of 26 patients were identified during the study period, of which 24 patients (92.30%) were treated with SEMS as a bridge-to-surgery and 2 (7.69%) as palliation. In 22 cases (80.76%), the stenosis was localized to the left side. Clinical success with resolution of bowel obstructions was achieved in 22 (84.61%) patients within a short period of time. Among patients treated successfully with SEMS insertion as bridge to surgery (n = 22), 20 (90.9%) underwent one-stage surgery with primary anastomosis while 2 patients (9.09%) underwent colostomy due to intraoperative evidence of a covered perforation by cancer tissue in the pelvis. Patients with subclinical perforation developed an early peritoneal carcinomatosis, 10 patients treated with curative intent subsequently developed liver metastasis after 24 months. We reported an overall poor outcome among patients treated with the insertion of SEMS. This led us to think that, in some cases, occlusion may be better than a "silent" perforation.

Numerical solution of acoustic scattering by finite perforated elastic plates

PubMed Central

2016-01-01

We present a numerical method to compute the acoustic field scattered by finite perforated elastic plates. A boundary element method is developed to solve the Helmholtz equation subjected to boundary conditions related to the plate vibration. These boundary conditions are recast in terms of the vibration modes of the plate and its porosity, which enables a direct solution procedure. A parametric study is performed for a two-dimensional problem whereby a cantilevered perforated elastic plate scatters sound from a point quadrupole near the free edge. Both elasticity and porosity tend to diminish the scattered sound, in agreement with previous work considering semi-infinite plates. Finite elastic plates are shown to reduce acoustic scattering when excited at high Helmholtz numbers k0 based on the plate length. However, at low k0, finite elastic plates produce only modest reductions or, in cases related to structural resonance, an increase to the scattered sound level relative to the rigid case. Porosity, on the other hand, is shown to be more effective in reducing the radiated sound for low k0. The combined beneficial effects of elasticity and porosity are shown to be effective in reducing the scattered sound for a broader range of k0 for perforated elastic plates. PMID:27274685

Research in prevention of partial flap necrosis has recently concentrated on extending the safe length of a flap by ligating vessels of known territories. To advance this approach one step further, the authors decided to reveal the least invasive surgical strategy for transfer of angiosomes. The study was arranged into three experiments. In the first experiment (n = 17 rabbits), a cutaneous island flap model spanning four adjacent vascular territories was developed. In the second experiment (n = 15 rabbits), the flap model was used to test the possibility of desiccating those vessels supplying the angiosomes to be captured percutaneously with radiofrequency. The delay procedures were performed by means of minimal skin incisions, and the flaps were elevated after a 2-week delay period. In the third experiment, the effectiveness of selective interference of these pedicles was compared to minimize the number of target vessels for successful transfer of angiosomes. The mean surviving area of the new flap model was 63 +/- 2 percent. The mean surviving flap area was 97 +/- 3 percent for the endoscopy equivalent technique and 94 +/- 4 percent for radiofrequency delay. The results were statistically insignificant between these two groups. In experiment 3, comparison of the results yielded a statistically insignificant difference for flap survival area among all four of the groups. An alternative flap model is introduced for future investigation of the vascular delay process. Percutaneous desiccation of the perforators with radiofrequency was found to be a reliable method, and selective desiccation of the perforator(s) was as efficient as destruction of all vascular sources other than the pedicle.

Successful embolization of iatrogenic ruptured coronary artery using Onyx: a new technique.

Iatrogenic perforation of coronary artery is rare during percutaneous coronary intervention (PCI); however the complications are life-threatening. Patients in this clinical setting may be treated either by stent placement, closure of the perforation with fibrin glue or coils, or with emergency bypass surgery. Onyx, a new material that has been used successfully in cerebral arteries, represents a new and safe alternative. The advantage of Onyx is that it is easily injected through a microcatheter and it allows for a longer injection time having also the ability to reach difficult anatomical locations. We present the first case of successful embolization of a right coronary artery perforation during coronary angiography using Onyx.

The evidence base for coronary perforation (CP) occurring during percutaneous coronary intervention in patients with a history of coronary artery bypass surgery (PCI-CABG) is limited and the long-term effects unclear. Using a national PCI database, the incidence, predictors, and outcomes of CP during PCI-CABG were defined. Data were analyzed on all PCI-CABG procedures performed in England and Wales between 2005 and 2013. Multivariate logistic regressions and propensity scores were used to identify predictors of CP and its association with outcomes. During the study period, 309 CPs were recorded during 59 644 PCI-CABG procedures with the incidence rising from 0.32% in 2005 to 0.68% in 2013 ( P <0.001 for trend). Independent associates of perforation in native vessels included age, chronic occlusive disease intervention, rotational atherectomy use, number of stents, hypertension, and female sex. In graft PCI, predictors of perforation were history of stroke, New York Heart Association class, and number of stents used. In-hospital clinical complications including Q-wave myocardial infarction (2.9% versus 0.2%; P <0.001), major bleeding (14.0% versus 0.9%; P <0.001), blood transfusion (3.7% versus 0.2%; P <0.001), and death (10.0% versus 1.1%; P <0.001) were more frequent in patients with CP. A continued excess mortality occurred after perforation, with an odds ratio for 12-month mortality of 1.35 for perforation survivors compared with matched nonperforation survivors without a CP ( P <0.0001). CP is an infrequent event during PCI-CABG but is closely associated with adverse clinical outcomes. A legacy effect of perforation on 12-month mortality was observed. © 2017 American Heart Association, Inc.

Perforators are those which connect the superficial and deep venous system either directly to main veins or indirectly through the muscular and soleal venous plexus. The emergence of minimally invasive techniques like ambulatory phlebectomy (AP) and foam sclerotherapy (FS) has led to increasing interest about the appropriate therapy for the treatment of isolated perforator incompetence. There have been no studies which have compared the effectiveness of these in-office procedures in isolated perforator incompetence due to the low prevalence of cases. The primary goal of this study is to compare the clinical parameters (return to normal activity, primary symptom relief), functional parameters (procedure time, change in disease severity, course of venous ulcer), and duplex parameters (recurrence in treated veins, complete occlusion of treated veins) in the management of leg varicosities having isolated primary perforator incompetence by ambulatory phlebectomy and duplex guided foam sclerotherapy. Though the procedure time was shorter with FS than AP, the other parameters of primary symptom relief such as change in disease severity, faster healing of venous ulcer, complete occlusion of treated veins in follow-up duplex examination, and lower recurrence of treated veins are better with AP than FS. In conclusion, the interruption of perforators is effective in decreasing the symptoms of chronic venous insufficiency and for the rapid healing of ulcers. The interruption of the incompetent perforating veins appears to be essential to decrease ambulatory venous hypertension. It is apparent from this study that ambulatory phlebectomy stands distinct with enormous benefits and serves as a superior alternative to foam sclerotherapy in treating patients with isolated perforator incompetence.

The medial sural artery perforator (MSAP) flap is defined as a thin cutaneo-adipose perforator flap harvested on the medial aspect of the leg. The aims of this study were to describe the anatomical basis as well as the surgical technique and discuss the indications in head and neck reconstructive surgery. We harvested 10 MSAP flap on 5 fresh cadavers. For each case, the number and the location of the perforators were recorded. For each flap, the length of pedicle, the diameter of source vessels and the thickness of the flap were studied. Finally, we performed a clinical application of a MSAP flap. A total of 23 perforators with a diameter superior than 1mm were dissected on 10 legs. The medial sural artery provided between 1 and 4 musculocutaneous perforators. Perforators were located in average at 10.3cm±2cm from the popliteal fossa and at 3.6cm±1cm from the median line of the calf. The mean pedicle length was 12.1cm±2.5cm. At its origin, the source artery diameter was 1.8mm±0.25mm and source veins diameters were 2.45mm±0.9mm in average. There was no complication in our clinical application. This study confirms the reliability of previous anatomical descriptions of the medial sural artery perforator flap. This flap was reported as thin and particularly adapted for oral cavity reconstruction and for facial or limb resurfacing. Sequelae might be reduced as compared to those of the radial forearm flap with comparable results. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Perforations of the stomach and duodenum are common complications of peptic ulcer disease (PUD), abuse of non steroidal anti inflammatory drugs (NSAIDS) and gastric cancer. Being a life threatening complication of PUD, it needs special attention with prompt resuscitation and appropriate surgical management if morbidity and mortality are to be avoided. To determine the pattern and management outcome of perforated peptic ulcer disease PUD as seen in University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Rivers State, Nigeria). All the patients with perforated PUD that were managed at UPTH between January 2006 and December 2014 were studied. Relevant data were extracted from the case notes and analysed using the Statistical Package for Social Sciences (SPSS) version 17. Thirty six patients with perforated PUD were evaluated consisting of 28 males and 8 females with a male to female ratio of 3.5:1. Their ages ranged from 24 to 65 years with a mean of 42.1± 12.3 years and the peak age was at the third decade. After adequate resuscitation, all the patients had exploratory laparotomy. In 26 (72.2%) patients, the perforation was in the duodenum while in 10 (27.8%), it was in the stomach. Thirty two (88.9%) patients had Graham's omental patch repair of the perforation while simple closure only was done in 4 (11.1%) patients. Surgical site infection was the commonest post operative complication which was seen in 7 (19.4%) patients while 4 patients died giving a mortality rate of 11.1%. Perforated peptic ulcer predominantly affected young males and Graham's omental patch followed by Helicobacter pylori eradication was an effective treatment modality.

To investigate the distribution of the perforating branches artery of distally-based flap of sural nerve nutrient vessels and its clinical application. The origins and distribution of perforating branches artery of distally-based flap were observed on specimens of 30 adult cadaveric low limbs by perfusing red gelatin to dissect the artery. Among the 36 cases, there were 21 males, 15 females. Their ages ranged from 6 to 66, 35. 2 in average. The defect area was 3.5 cm x 2.5 cm to 17.0 cm x 11.0 cm. The flap taken ranged from 4 cm x 3 cm to 18 cm x 12 cm. The perforating branches artery of distally-based flap had 2 to 5 branches and originated from the heel lateral artery, the terminal perforating branches of peroneal artery (diameters were 0.6+/-0.2 mm and 0.8+/-0.2 mm, 1.0 +/- 1.3 cm and 2.8 +/- 1.0 cm to the level of cusp lateral malleolus cusp). The intermuscular septum perforating branches of peroneal artery had 0 to 3 branches. Their rate of presence was 96.7%, 66.7% and 20.0% respectively (the diameters were 0.9 +/- 0.3, 1.0 +/- 0.2 and 0.8 +/- 0.4 mm, and their distances to the level of cusp of lateral malleolus were 5.3 +/- 2.1, 6.8 +/- 2.8 and 7.0 +/- 4.0 cm). Those perforating branches included fascia branches, cutaneous branches, nerve and vein nutrient branches. Those nutrient vessels formed longitudinal vessel chain of sural nerve shaft, vessel chain of vein side and vessel network of deep superficial fascia. The distally-based superficial sural artery island flap was used in 18 cases, all flaps survived. Distally-based sural nerve, small saphenous vein, and nutrient vessels of fascia skin have the same origin. Rotation point of flap is 3.0 cm to the cusp of lateral malleolus, when the distally-based flap is pedicled with the terminal branch of peroneal artery. Rotation point of flap is close to the cusp of lateral malleolus, when the distally-based flap is pedicled with the heel lateral artery.

Acute diffuse peritonitis is a common surgical emergency worldwide and a major contributor to non-trauma related death toll. Its causes vary widely and are correlated with mortality. Community acquired peritonitis seems to play a major role and is frequently related to hollow viscus perforation. Data on the outcome of peritonitis in the tropics are scarce. The aim of this study is to analyze the impact of tropic latitude causes of diffuse peritonitis on morbidity and mortality. We retrospectively reviewed the records of 305 patients operated on for a diffuse peritonitis in two regional hospitals in the South-West Region of Cameroon over a 7 years period. The contributions of various causes of peritonitis to morbidity and mortality were analyzed. The diagnosis of diffuse peritonitis was suggested on clinical ground only in more than 93 % of cases. The most common causes of diffuse peritonitis included peptic ulcer perforation (n = 69), complications of acute appendicitis (n = 53) and spontaneous perforations of the terminal ileum (n = 43). A total of 142 complications were recorded in 96 patients (31.5 % complication rate). The most common complications included wound dehiscence, sepsis, prolonged paralytic ileus and multi-organ failure. Patients with typhoid perforation of the terminal ileum carried a significantly higher risk of developing a complication (p = 0.002). The overall mortality rate was 15.1 %. The most common cause of death was septic shock. Differential analysis of mortality of various causes of peritonitis indicated that the highest contributors to death toll were typhoid perforation of terminal ileum (34.7 % of deaths), post-operative peritonitis (19.5 %) and peptic ulcer perforation (15.2 %). The diagnosis of diffuse peritonitis can still rely on clinical assessment alone in the absence of sophisticated imaging tools. Peptic ulcer and typhoid perforations are still major contributors to death toll. Patients presenting with these conditions require specific attention and prevention policies must be reinforced.

A skin defect of the hand and wrist is a common manifestation in industrial crushing injuries, traffic accidents or after excision of tumors. We reconstructed a skin defect in the ulnar aspect of the hand and wrist with a perforator-based propeller flap from the ulnar artery. The aims of our study are to evaluate the utility and effectiveness of this flap and to discuss the advantages and disadvantages of the flap in hand and wrist reconstruction with a review of the literature. Between April 2011 and November 2016, five cases of skin defect were reconstructed with a perforator-based propeller flap from the ulnar artery. There were four males and one female. The age of patients ranged from 36 to 73 years. Skin defect sites were on the dorso-ulnar side of the hand in three cases and palmar-ulnar side of the wrist in two cases. The size of the skin defect ranged from 4 × 3 cm to 8 × 5 cm. We evaluated the viability of the flap, postoperative complication and patient's satisfaction. There was no failure of flap in all cases. The size of the flap ranged from 4 × 4 cm to 12 × 4 cm. One patient, who had a burn scar contracture, presented with limited active and passive motion of the wrist after the operation. The other patients had no complications postoperatively. Cosmetic results of the surgery were excellent in one patient, good in three patients, and fair in one patient. The fasciocutaneous propeller flap based on a perforating branch of the ulnar artery is a reliable treatment option for the ulnar side skin defect of the hand and wrist.

Few studies in the recent literature have investigated the reliability of dorsal intercostal artery perforator (DICAP) flap in posterior trunk reconstruction. The purpose of this report is to describe our clinical experience with the use of DICAP flaps in a cohort of oncological patients. Twenty patients underwent posterior trunk reconstruction with DICAP based flaps. Patients age ranged from 45 to 76 years. All defects resulted from skin cancer ablation. Defect sizes ranged from 4 × 4 to 6 × 8 cm. The flaps were mobilized in V-Y or propeller fashion. The flaps were islanded on 1 (12 cases), 2 (6 cases), or 3 (2 cases) perforators. Donor sites were always closed primarily. Eleven V-Y advancement flaps were performed; one of these was converted to a perforator-plus peninsular flap design, which retained an additional source of blood supply from the opposite skin bridge. Nine flaps were mobilized in propeller fashion. Flap dimensions ranged from 4 × 6 to 6 × 14 cm. Mean operative time was 70 min. One V-Y flap complicated with marginal necrosis that healed with no need for reintervention. All the other flaps survived uneventfully. No other complications were observed at recipient and donor sites. Follow-up ranged from 3 months to 2 years. All the patients were satisfied with the surgical outcome. DICAP based flaps proved to be a reliable option to resurface posterior trunk defects following oncological resection, allowing to achieve like-with-like reconstruction with excellent contour and minimal donor-site morbidity. © 2015 Wiley Periodicals, Inc.

To describe the characteristics and management of foreign-body ingestions, with predominantly intentional ingestion, in a lower socioeconomic status population. A retrospective case series. An urban county hospital. Patients >/=17 years old, with foreign-body ingestions between 2000 and 2006. Characteristics of ingestion cases, endoscopic extraction, need for surgery, and complications. Among 262 cases, 92% were intentional, 85% involved psychiatric patients, and 84% occurred in patients with prior ingestions. The time from ingestion to presentation was >48 hours in 168 cases (64%). The overall success rate for endoscopic extraction was 90% (165/183 cases). Surgery was performed in 30 cases (11%) and was more common for objects beyond the pylorus versus objects above the pylorus (16/43 [37%] vs 10/151 [7%], respectively) and in cases with a greater delay from ingestion to presentation (25/168 [15%] if >48 hours vs 4/77 [5%] if 48 hours vs 14/165 [8%] if

the presence of duodenal diverticula was first described in 1710 by Chromel. Duodenal diverticulum is the second most common site of diverticula in the digestive tract. Anatomically duodenal diverticula are located in 10 to 67% in the second portion of duodenum, and its finding in most cases incidental. About 90% of patients appear asymptomatic, manifesting symptoms mostly once established complications such as: gastrointestinal bleeding and perforation. 78-years-old woman who attended our Emergency department with dyspnea, moderate epigastralgia, abdominal bloating, constipation and difficulty to pass gas; Laparotomy was performed to identify duodenal diverticulum in the third portion of the duodenum with a perforation of 5 mm in its cupula. It proceeds with diverticulectomy. The diagnosis of duodenal diverticulum as a cause of acute abdomen must be considered in our differential diagnosis in acute abdomen supported by imaging and endoscopy. The surgical management of duodenal diverticulum, in particular the resection of the diverticulum, remains as the recommendation for treatment with less morbidity and a good recovery.

We report a case of esophageal perforation caused by an explosion, but which was not diagnosed until 3 days after the injury. A 53-year-old worker sustained superficial dermal burns to his trachea, face, neck, and legs during an explosion. The burns were treated conservatively at a local hospital, but he was transferred to our hospital 3 days after the injury, when mediastinal emphysema and bilateral pleural effusion became evident. An esophagogram followed by computed tomography showed an esophageal perforation caused by the blast injury, and we performed an esophagectomy with recontruction of the gastric tube. After the operation, an X-ray showed a foreign body in the lower abdomen, which we found in the upper thoracic esophagus on the day of injury. We surmised that the patient had inadvertently swallowed a foreign body, which had been heated and scattered by the explosion, and it had melted the upper thoracic esophagus.

Fouling resilient perforated feed spacers for membrane filtration.

2018-04-24

The improvement of feed spacers with optimal geometry remains a key challenge for spiral-wound membrane systems in water treatment due to their impact on the hydrodynamic performance and fouling development. In this work, novel spacer designs are proposed by intrinsically modifying cylindrical filaments through perforations. Three symmetric perforated spacers (1-Hole, 2-Hole, and 3-Hole) were in-house 3D-printed and experimentally evaluated in terms of permeate flux, feed channel pressure drop and membrane fouling. Spacer performance is characterized and compared with standard no perforated (0-Hole) design under constant feed pressure and constant feed flow rate. Perforations in the spacer filaments resulted in significantly lowering the net pressure drop across the spacer filled channel. The 3-Hole spacer was found to have the lowest pressure drop (50%-61%) compared to 0-Hole spacer for various average flow velocities. Regarding permeate flux production, the 0-Hole spacer produced 5.7 L m -2 .h -1 and 6.6 L m -2 .h -1 steady state flux for constant pressure and constant feed flow rate, respectively. The 1-Hole spacer was found to be the most efficient among the perforated spacers with 75% and 23% increase in permeate production at constant pressure and constant feed flow, respectively. Furthermore, membrane surface of 1-Hole spacer was found to be cleanest in terms of fouling, contributing to maintain higher permeate flux production. Hydrodynamic understanding of these perforated spacers is also quantified by performing Direct Numerical Simulation (DNS). The performance enhancement of these perforated spacers is attributed to the formation of micro-jets in the spacer cell that aided in producing enough unsteadiness/turbulence to clean the membrane surface and mitigate fouling phenomena. In the case of 1-Hole spacer, the unsteadiness intensity at the outlet of micro-jets and the shear stress fluctuations created inside the cells are higher than those observed with other perforated spacers, resulting in the cleanest membrane surface.

Assessment of appendicitis during a weeknight or weekend shift (after-hours period, AHP) might be more costly and less effective than its assessment on a weekday shift (standard hours period, SHP) because of increased costs (staff premium fees) and perforation risk (longer delays and less experience of fellows). The objectives were to compare the costs and effectiveness of assessing children with suspected appendicitis who required a laparotomy and had US or CT after-hours with those of assessing children during standard hours, and to evaluate the importance of diagnostic imaging (DI) within the overall costs. We retrospectively microcosted resource use within six areas of a tertiary hospital (emergency [ED], diagnostic imaging (DI), surgery, wards, transport, and pathology) in a tertiary hospital. About 41 children (1.8-17 years) in the AHP and 35 (2.9-16 years) in the SHP were evaluated. Work shift effectiveness was measured with a histological score that assessed the severity of appendicitis (non-perforated appendicitis: scores 1-3; perforated appendicitis: score 4). The SHP was less costly and more effective regardless of whether the calculation included US or CT costs only. For a salary-based fee schedule, 733 US dollars were saved per case of perforated appendicitis averted in the SHP. For a fee-for-service payment schedule, 847 dollars were saved. Within the overall budget, the highest costs were those incurred on the ward for both shifts. The average cost per patient in DI ranged from 2 to 5% of the total costs in both shifts. Most perforation cases were found in the AHP (31.7%, AHP vs. 17.1%, SHP), which resulted in higher ward costs for patients in the AHP. A higher proportion of severe cases was seen in the AHP, which led to its higher costs. As a result, the SHP dominated the AHP, being less costly and more effective regardless of the fee schedule applied. The DI costs contributed little to the overall cost of the assessment of appendicitis.

Although the surgical treatment of patients with perforated duodenal ulcer is the method of choice, the introduction of effective pharmacotherapy has changed the surgical strategy. Nowadays less extensive procedures are chosen more frequently. The introduction of laparoscopic procedures had a significant impact on treatment results. To present our experience in the treatment of perforated duodenal ulcer in two periods, by comparing open radical anti-ulcer procedures with laparoscopic ulcer repair. The analysis covered patients operated on for perforated duodenal ulcer. Two groups of patients were compared. Group 1 included 245 patients operated on in the period 1980-1994 with a traditional method (pyloroplasty + vagotomy) before introduction of proton pump inhibitors (PPI). Group 2 included 106 patients treated in the period 2000-2014 with the laparoscopic technique supplemented with PPI therapy. Groups were compared in terms of patients' demographic structure, operative time, complication rate and mortality. The mean operative time in group 1 was shorter than in group 2 (p < 0.0001). Complications were noted in 57 (23.3%) patients in group 1 and 14 (13.5%) patients in group 2 (p = 0.0312). Reoperation was necessary in 13 (5.3%) cases in group 1 and in 5 cases in group 2 (p = 0.8179). The mortality rate in group 1 was significantly higher than in group 2 (10.2% vs. 2.8%, p = 0.0192). In group 1, median length of hospital stay was 9 days and differed significantly from group 2 (6 days, p < 0.0001). Within the last 30 years, significant changes in treatment of perforated peptic ulcer (PPU) have occurred, mainly related to abandoning routine radical anti-ulcer procedures and replacing the open technique with minimally invasive surgery. Thus it was possible to improve treatment results by reducing complication and mortality rates, and shortening the length of hospital stay. Although the laparoscopic operation is longer, it improves outcomes. In the authors' opinion, in each patient with suspected peptic ulcer perforation, laparoscopy should be the method of choice.

Twelve patients with iatrogenic bile duct injuries occurred during laparoscopic cholecystectomy (LC) were treated from June 1992 to May 1994. All the patients underwent re-operation and were cured. The causes and characteristics of the injuries were: (1) perforation of the common hepatic or common bile duct caused by dissecting hook (3 cases); (2) necrosis and perforation of the common hepatic duct due to diathermic injury (1 case); (3) clamping of the common hepatic duct by Ti clip (1 case); (4) secondary high bile duct stricture following a failed end-to-end anastomosis or hepatico-cholangio-jejunostomy of the amputated common hepatic duct (5 cases); (5) delayed high bile duct stricture (2 cases). It is emphasized that the severity of bile duct injuries by LC be should not overlooked, and more experience in this field be accumulated to avoid this serious complication.

The clinical and microscopic appearances of inflammatory bowel disease may be very similar to those of amebic colitis. The coexistence of invasive amebiasis with inflammatory bowel disease may have disastrous results. Patients with inflammatory bowel disease have a greater prevalence of amebiasis, but this association is more significant for ulcerative colitis. There have been very few reports in the literature presenting the superimposition of amebiasis on Crohn's disease. In this report, a rare case of Crohn's colitis with superimposed amebiasis resulting in colonic perforation is presented. Patients with inflammatory bowel disease traveling to endemic areas may benefit from receiving a course of prophylactic anti-amebic medication.

Gastric cancer perforation can occurs in advanced stage of the disease and is often associated with a high morbidity and mortality. Peritonitis due to perforation needs emergency laparotomy and different surgical procedures can be performed for definitive treatment. Surgical procedures largely depend on the stage of the disease and general condition of the patient. This study was carried out to evaluate the outcome and role of different surgical procedures in gastric cancer perforation. Medical record of patients with gastric perforation, who were treated during ten years period, was reviewed retrospectively. Data regarding clinical presentation, surgical procedures, staging and survival of patients were obtained. Features suggestive of diffuse peritonitis were evident in all cases. The majority of the patients underwent emergency surgery except one who died during resuscitation. The majority of patients were in stage III and stage IV. Surgical procedure includes simple closure and omental patch in five patients, simple closure and gastrojejunostomy in nine patients, gastrectomy in six patients and Devine's antral exclusion in one patient. Surgical site infection was the most common (45.5%) postoperative complication. Four patients died within one month of the surgery. Three patients who underwent gastrectomy survived for one year and one patient survived for five years. Although gastric cancer perforation usually occurs in advanced stage of the disease, curative resection should be considered as far as possible.

Dyspnea and chest pain are common presenting complaints to the ED, and coupled together can present a challenging diagnostic dilemma in patients in extremis. A thoughtful evaluation is required, giving due diligence to the immediate life threats as well as multiple etiologies which can cause serious morbidity. A perforated peptic ulcer is one such possibility and requires rapid diagnosis and prompt intervention to avoid the associated high risk of morbidity and mortality. We present a case report of a 54 year old man with respiratory distress and chest pain as the initial Emergency Department presentation of a perforated duodenal ulcer. We discuss an unusual presentation of a perforated duodenal ulcer that was recognized in the emergency department and treated promptly. The patient was surgically treated immediately, had a prolonged and complicated post-operative course, but is ultimately doing well. We also provide a brief literature review of the risk factors, imaging choices, and management decision required to treat a perforated ulcer. Perforated ulcers can have highly varied presentations and are occasionally difficult to diagnose in a complicated patient. Knowledge of the risk factors and a thorough history and physical can point to the diagnosis, but timely and appropriate imaging is often required because delays in diagnosis and treatment lead to poor outcomes. Early administration of antibiotics and immediate surgical repair are necessary to limit morbidity and mortality.

2015-08-01

We report the case of a 50-year-old paraplegic man with a complicated grade III/IV ischiatic pressure sore treated with a propeller flap based on the first perforator of the profunda femoris artery. Our aim was to surgically reconstruct an ischiatic pressure sore in a patient with ankylosis using a fasciocutaneous perforator propeller flap obtained from the posterior region of the thigh. Our decision to perform a profunda femoris artery perforator propeller flap reconstruction was mainly due to the anatomical contiguity of the flap with the site of the lesion and the good quality of the skin harvested from the posterior region of the thigh. The use of the perforator fasciocutaneous flap represents a muscle-sparing technique, providing a better long-term result in surgical reconstruction. The choice of the 180-degree propeller flap was due to its ability to provide a good repair of the pressure ulcer and to pass over the ischiatic prominence in the patient in the forced decubitus position. The operatory course did not present any kind of complication. Using this reconstructive treatment, we have obtained complete coverage of the ischiatic pressure sore.

The clinical features of tuberculous otitis media (TOM) have changed. This study was performed to evaluate changing trends in the clinical manifestations of TOM. We reviewed a series of 12 cases of TOM (13 ears) recently treated at Osaka Prefectural Habikino Hospital. The results showed a mean age of 41 years and a male predominance of 1.4 to 1. Central or total perforations of the tympanic membrane were observed in most cases, but none of the patients had multiple perforations. Nine patients (75%) had active pulmonary tuberculosis. Normal lung status or inactive pulmonary tuberculosis was significantly more frequent in the older age group. Diagnosis of primary TOM required more time than that of secondary TOM. Most cases of primary TOM had high infectiousness of the primary lesion. We summarize the clinical features of patients who should be evaluated for TOM.

Free style perforator based propeller flaps: Simple solutions for upper extremity reconstruction!

The introduction of perforator flaps by Koshima et al. was met with much animosity in the plastic surgery fraternity. The safety concerns of these flaps following the intentional twist of the perforators have prevented widespread adoption of this technique. Use of perforator based propeller flaps in the lower extremity is gradually on the rise, but their use in upper extremity reconstruction is infrequently reported, especially in the Indian subcontinent. We present a retrospective series of 63 free style perforator flaps used for soft tissue reconstruction of the upper extremity from November 2008 to June 2013. Flaps were performed by a single surgeon for various locations and indications over the upper extremity. Patient demographics, surgical indication, defect features, complications and clinical outcome are evaluated and presented as an uncontrolled case series. 63 free style perforator based propeller flaps were used for soft tissue reconstruction of 62 patients for the upper extremity from November 2008 to June 2013. Of the 63 flaps, 31 flaps were performed for trauma, 30 for post burn sequel, and two for post snake bite defects. We encountered flap necrosis in 8 flaps, of which there was complete necrosis in 4 flaps, and partial necrosis in four flaps. Of these 8 flaps, 7 needed a secondary procedure, and one healed secondarily. Although we had a failure rate of 12-13%, most of our failures were in the early part of the series indicative of a learning curve associated with the flap. Free style perforator based propeller flaps are a reliable option for coverage of small to moderate sized defects. Therapeutic IV.

Safely Combining Abdominoplasty with Aggressive Abdominal Liposuction Based on Perforator Vessels: Technique and a Review of 300 Consecutive Cases

PubMed Central

Smith, Lane F.

2015-01-01

Background: There continues to be controversy about performing abdominoplasty concurrently with abdominal liposuction. The concern is that liposuction on the already vascularly compromised abdominal flap will lead to increased complications and flap necrosis. The central abdomen is supplied by the epigastric system. If perforator vessels from this system are spared, the blood supply to the abdomen can be spared and liposuction should be able to be safely performed on the elevated abdominal flap. The purpose of this study was to evaluate the safety of abdominoplasty with concurrent abdominal liposuction when a perforator vessel is spared. Methods: A standard abdominoplasty was performed, sparing one or two perforator vessels from the deep superior epigastric artery system. A retrospective chart review of 300 consecutive patients who underwent abdominoplasty surgery combined with concurrent abdominal liposuction was performed. Complications, total volume of abdominal liposuction, and results were reviewed. Results: The overall complication rate was 17.3 percent (52 patients). Sixteen percent (48 patients) suffered minor complications and 1.3 percent (four patients) suffered major complications. Conclusions: Abdominoplasty can be combined safely with concurrent abdominal liposuction when a perforator vessel is spared. The combination of concurrent liposuction with abdominoplasty showed no increase in complication rates when a perforator vessel was spared. The perforator vessels are located consistently in a 2-cm radius located 4 cm from the midline and 6 cm from the subcostal margin. The potential advantages of abdominoplasty with concurrent liposuction include a better postoperative cosmetic result. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID:25919250

To discuss the effectiveness of distal palm perforator mini-flap in the treatment of scar contracture of digital web-spaces. Between August 2008 and March 2010, 6 cases of scar contracture of digital web-spaces were treated, including 4 males and 2 females and aging 16-68 years (mean, 45 years). The causes were burn injury, twisting injury, and crush injury in 2 cases, respectively. The disease duration was from 3 months to 3 years. The affected digital web-spaces were from index finger to middle finger in 2 cases, from middle finger to ring finger in 3 cases, and from ring finger to small finger in 1 case. The maximum abduction degree of digital web-spaces was 5-10 degrees. The sizes and the depths of reshape of digital web-spaces disappeared. The defect size ranged from 20 mm x 8 mm to 30 mm x 13 mm after opening digital web-spaces. The size of the distal palm perforator mini-flap ranged from 25 mm x 10 mm to 35 mm x 15 mm. The donor sites were sutured directly. All 6 flaps survived and got primary healing. Incisions at donor sites healed by first intention. All patients were followed up 6-12 months. The reconstructed digital web-spaces had good appearance and soft texture. The range of motion of metacarpophalangeal joint was normal. The sizes and the depths of reshape of digital web-spaces were similar to normal ones. The maximum abduction degree of digital web-spaces was 40-60 degrees. There was no scar contracture of incision of palm. The shape of flaps and function of the fingers were satisfactory after 6-12 months of follow-up. It is an ideal method to treat scar contracture of digital web-spaces with distal palm perforator mini-flap.

Foreign body (FB) ingestion results in perforation in 1% of cases and is associated with significant morbidity and rarely mortality. Clinical presentation is variable and can present a diagnostic challenge. We report our experience and management of a patient with a delayed presentation of a sigmoid colon foreign body as a result of ingestion of a dental plate. A 67 year old female attended the colorectal outpatient clinic following an incidental finding of a sigmoid mass on computed tomography (CT) abdomen. Further investigation identified a dental plate impacted in a thickened sigmoid colon. On further questioning the patient recalled losing her dentures three years previously. At surgery the dental plate had partially eroded through the sigmoid colon into the pelvic side wall. A sigmoid colectomy and hand sewn end-to-end colo-colic anastomosis was performed. Localised perforation following ingestion of a foreign body may result in significant morbidity. Extra luminal migration and local inflammatory response resulted in the formation of a walled off collection. Delayed complications of perforation include abscess and fistula formation. Clinicians need to exhibit a high index of suspicion when treating edentulous patients and alcohol and drug abusers who present with an acute abdomen or a sub-acute presentation with associated atypical imaging and endoscopic findings. The decision regarding intervention and management strategy in cases of perforation by foreign body depends on chronicity of the case, extent of localised or diffuse peritonitis, and size of the lesion or area of bowel involved.

Reconstruction of ischial pressure sore defects is challenging due to extensive bursas and high recurrence rates. In this study, we simultaneously applied a muscle flap that covered the exposed ischium and large bursa with sufficient muscular volume and a profunda femoris artery perforator fasciocutaneous flap for the management of ischial pressure sores. We retrospectively analyzed data from 14 patients (16 ischial sores) whose ischial defects had been reconstructed using both a profunda femoris artery perforator flap and a muscle flap between January 2006 and February 2014. We compared patient characteristics, operative procedure, and clinical course. All flaps survived the entire follow-up period. Seven patients (50%) had a history of surgery at the site of the ischial pressure sore. The mean age of the patients included was 52.8 years (range, 18-85 years). The mean follow-up period was 27.9 months (range, 3-57 months). In two patients, a biceps femoris muscle flap was used, while a gracilis muscle flap was used in the remaining patients. In four cases (25%), wound dehiscence occurred, but healed without further complication after resuturing. Additionally, congestion occurred in one case (6%), but resolved with conservative treatment. Among 16 cases, there was only one (6%) recurrence at 34 months. The combination of a profunda femoris artery perforator fasciocutaneous flap and muscle flap for the treatment of ischial pressure sores provided pliability, adequate bulkiness and few long-term complications. Therefore, this may be used as an alternative treatment method for ischial pressure sores.

The lumbar region is a potential donor site for perforator-based rotational or free flaps or as a recipient site for free flaps to obtain coverage for deficits in the sacral region. Because of the lack of consensus regarding the microvascular anatomy of this potential flap site, a robust investigation of the anatomy of this region is required. Three-dimensional reconstructions (n = 6) of the microvasculature of the lumbar region were generated using MIMICS software (Materialise, Belgium) for each of the four paired lumbar vessels. Diameter, course, and pedicle length were recorded for all lumbar artery (LA) perforators. Statistical analysis was performed using SigmaStat 4.0 and graphs were generated using GraphPad Prism 6 Software. Perforators arising from the first pair of LAs are reliably detected along the inferior margin of the 12th rib, extending inferiorly and laterally from the midline while perforators arising from the fourth pair of LA perforate the fascia along a horizontal plane connecting the posterior iliac crests. There are significantly more cutaneous perforators arising from the first (L1) and fourth (L4) pairs of LA than from the second (L2) and third (L3) (mean ± SD: L1, 5.5 ± 1.2; L2, 1.4 ± 0.7; L3, 1.3 ± 0.7; L4, 4.8 ± 1.0; P < 0.05). The average perforator diameter arising from L1 is greater than those arising from L4 (diameter ± SD: L1, 1.2 mm ± 0.2 >L4, 0.8 mm ± 0.2; P < 0.0001). L1 and L4 perforators have longer pedicle lengths than those arising from L2 and L3 (length ± SD: L1, 98.2 mm ± 57.8; L4, 106.1 mm ± 23.3 >L2, 67.5 mm ± 27.4; L3, 78.5 mm ± 30.3; P < 0.05). Perforators arising from the first and fourth LAs arise in a predictable fashion, have adequate pedicle lengths, and are of suitable diameter to support a perforator flap. We present a case to support the potential use of this flap for microvascular breast reconstruction.

Surgical technique for reconstruction of the nasal septum: the pericranial flap.

We describe a new technique for the surgical reconstruction of large-sized anterior septal perforations based on the pericranial flap. The technique requires a standard open rhinoplasty combined with a pericranial flap harvested after a bicoronal approach and tunnelled to the nasal cavity. We present the case of a man with complete destruction of the nasal septum as a result of chronic cocaine abuse. Surgery resulted in a permanent and complete closure of the perforation. The main advantage of this technique is the use of well-vascularized autogenous tissue and the minimal donor site morbidity. This technique provides a new method to close large nasal perforations.

Ovarian cancer often presents at an advanced stage, but tends to be an intra-peritoneal disease that respects peritoneal planes. Thus, colo-rectal perforation of the tumor is an extremely rare presentation. The surgical treatment of malignant colo-ovarian fistula should include complete cyto-reduction at the same time as the treatment of the fistula. However, prognosis remains poor, because of the advanced stage of neoplasia. We report the case of a patient with an ovarian malignant tumor perforating into the recto-sigmoid colon. CT scan was the cornerstone of the radiological diagnosis. We managed to perform a complete cyto-reduction, including an en-bloc resection of the uterus, the mass, adnexa and recto-sigmoid with removal of the associated pelvic abscess.

Free sural artery perforator flap: An occasional gift in oral cavity reconstruction.

The medial sural artery perforator (MSAP) flap is becoming a popular strategy for reconstructing intraoral defects. We present a case in which no MSAPs were present, however, a perforator-based calf flap was successfully raised on the sural artery and used for tongue reconstruction. A corresponding anatomic study was undertaken to establish if this finding was reproducible. A 58-year-old woman underwent left hemiglossectomy for a squamous cell carcinoma of the tongue. Subsequently, 6 fresh frozen cadaveric limbs were dissected examining the blood supply of the posterior calf skin. The sural artery perforator (SAP) flap successfully reconstructed the defect. Our cadaveric study similarly demonstrated a septocutaneous SAP supplying the posterior calf skin in 1 of 6 limbs. SAPs allow a favorable flap dissection, as opposed to the musculocutaneous course of MSAPs. Our findings provide further evidence of the versatility of the calf donor site. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2454-E2456, 2016. © 2016 Wiley Periodicals, Inc.

Perforated posterior cecal diverticulum: challenges in establishing an accurate preoperative diagnosis of a rare emergency.

Solitary cecal diverticulitis is a rare cause of abdominal pain in Western countries. The preoperative diagnosis is very difficult to establish and most patients are operated on with a presumptive diagnosis of acute appendicitis based on clinical grounds. We describe a very rare case of perforated posterior cecal diverticulum and discuss the challenges in establishing a correct preoperative diagnosis. We conclude that although very rare, the possibility of perforated posteriorcecal diverticulum should always be considered in the differential diagnosis of patients presenting with atypical clinical manifestations of acute appendicitis. A perforation of a posterior cecal diverticulum maybe associated with a mild clinical course without signs of peritonitis. Athorough preoperative evaluation including a computed tomography scan is essential in order to establish a correct preoperative diagnosis which is of utmost importance for treatment planning in the emergency setting. Simple diverticulectomy is an effective surgical treatment in the absence of extensive inflammatory changes and when a colonic tumor can be ruled out.

For extensive postburn neck deformities, the preexpanded flaps in the upper back region were used and gained a uniform skin appearance and esthetic contours. Free-style perforator-based free-tissue transfer that represents the most recent advance in reconstructive surgery may provide more versatility of these flaps. We retrospectively reviewed 31 patients treated at our institution for postburn neck contracture from March 2010 to May 2016. Various upper back flaps were designed according to the dominant perforators and the shape of the defect after fully releasing the neck contracture. Thirty-one patients received neck reconstructions with the versatile applications of the preexpanded upper back perforator flaps. Tip necrosis was observed in one case, and the others survived completely. The donor sites were all primarily closed. No incision dehiscence was observed. The free-style design has significantly increased the potential and versatility of the upper back flaps in reconstruction of severe neck scar contracture.

We encountered a case of sealed perforated duodenal ulcer in a 75-year-old woman with rheumatoid arthritis and chronic renal failure. Abdominal sonography showed a bright linear echo within the thickened anterior wall of the duodenal bulb and the presence of free air at the anterior surface of the liver. We found no signs of direct communication between the duodenal lumen and the peritoneal cavity or any free fluid. On follow-up sonography performed every 2 days during the first week of the patient's hospitalization, no free fluid was found in the abdomen. The use of sonography to diagnose this patient's sealed perforated duodenal ulcer and to monitor the ulcer for the appearance of free fluid allowed us to provide successful nonsurgical management to this patient. We believe that the use of abdominal sonography in all patients suspected of having a perforated duodenal ulcer may help increase the diagnostic accuracy of this modality and may reduce the need for surgery in such patients.

Thin perforated membranes with ordered pores are ideal barriers for high-resolution and high-efficiency selective transport and separation of biological species. However, for self-assembled thin membranes with a thickness less than several micrometers, an additional step of transferring the membranes onto porous supports is generally required. In this article, we present a facile transfer-free strategy for fabrication of robust perforated composite membranes via the breath figure process, and for the first time, demonstrate the application of the membranes in high-resolution cell separation of yeasts and lactobacilli without external pressure, achieving almost 100% rejection of yeasts and more than 70% recovery of lactobacilli with excellent viability. The avoidance of the transfer step simplifies the fabrication procedure of composite membranes and greatly improves the membrane homogeneity. Moreover, the introduction of an elastic triblock copolymer increases the interfacial strength between the membrane and the support, and allows the preservation of composite membranes in a dry state. Such perforated ordered membranes can also be applied in other size-based separation systems, enabling new opportunities in bioseparation and biosensors.

Perforated plates for cryogenic regenerators and method of fabrication

Hendricks, J.B.

1994-03-29

Perforated plates having very small holes with a uniform diameter throughout the plate thickness are prepared by a [open quotes]wire drawing[close quotes] process in which a billet of sacrificial metal is disposed in an extrusion can of the plate metal, and the can is extruded and restacked repeatedly, converting the billet to a wire of the desired hole diameter. At final size, the rod is then sliced into wafers, and the wires are removed by selective etching. This process is useful for plate metals of interest for high performance regenerator applications, in particular, copper, niobium, molybdenum, erbium, and other rare earth metals. Er[sub 3]Ni, which has uniquely favorable thermophysical properties for such applications, may be incorporated in regions of the plates by providing extrusion cans containing erbium and nickel metals in a stacked array with extrusion cans of the plate metal, which may be copper. The array is heated to convert the erbium and nickel metals to Er[sub 3]Ni. Perforated plates having two sizes of perforations, one of which is small enough for storage of helium, are also disclosed. 10 figures.

Constipation is a common complaint, frequently treated with cleansing enema. Enemas can be very effective but may cause serious adverse events, such as perforation or metabolic derangement. Our aim was to evaluate the outcome of the use of cleansing enema for acute constipation and to assess adverse events within 30 days of therapy. We performed a two-phase study: an initial retrospective and descriptive study in 2010, followed by a prospective study after intervention, in 2011. According to the results of the first phase we established guidelines for the treatment of constipation in the Emergency Department and then used these in the second phase. There were 269 and 286 cases of severe constipation in the first and second periods of the study, respectively. In the first study period, only Fleet® Enema was used, and in the second, this was changed to Easy Go enema (free of sodium phosphate). There was a 19.2% decrease in the total use of enema, in the second period of the study (P < 0.0001). Adverse events and especially, the perforation rate and the 30-day mortality in patients with constipation decreased significantly in the second phase: 3 (1.4%) versus 0 (P = 0.0001) and 8 (3.9%) versus 2 (0.7%) (P = 0.0001), for perforation and death in the first and second period of the study, respectively. Enema for the treatment of acute constipation is not without adverse events, especially in the elderly, and should be applied carefully. Perforation, hyperphosphatemia (after Fleet Enema), and sepsis may cause death in up to 4% of cases. Guidelines for the treatment of acute constipation and for enema administration are urgently needed.

To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas. From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula. In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life-threatening upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%). This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Here we described a case in which a patient underwent emergency laparotomy for acute peritonitis and sigmoid perforation under general anesthesia with a history of heart transplantation. A good knowledge in the physiology of the transplanted heart is critical for effective and safe general anesthesia. We chose etomidate that have a weaker impact on cardiovascular function plus propofol for induction, and propofol plus cisatracurium for maintenance with intermittently analgesics and vasoactive drugs to facilitate the anesthesia. In addition, fluid input, electrolyte and acid-base balance were well adjusted during the whole procedure. The patient was in good condition after the surgery. In this case report we are aiming to provide some guidance for those scheduled for non-cardiac surgery after heart transplant. PMID:26379997

Ingestion of liquid nitrogen is rare but carries catastrophic complications related to barotrauma to the gastrointestinal tract. We describe a case of ingestion of liquid nitrogen followed by gastric perforation and respiratory insufficiency and discuss the mechanism of injury and management of this condition. Liquid nitrogen is widely available and is frequently used in classroom settings, in gastronomy, and for recreational purposes. Given the potentially lethal complications of ingestion, regulation of its use, acquisition, and storage may be appropriate.

Mucocele of the appendix is a rare clinicopathological entity simulating acute appendicitis. The most common form of the mucocele is cystadenoma, which is characterized by luminal dilatation producing large amounts of mucin. We present a new case of a giant mucocele of appendix with mucinous cystadenoma. A 61-year-old female was admitted with complaints of severe lower right quadrant pain. Ultrasonography and computed tomography (CT) suggested that it was a mucocele, but due to severity of pain, she underwent an emergency operation. Fortunately, without a perforation, it was a giant mucocele and the operation was terminated with an uneventful appendectomy with segmental cecal resection. The histopathological evaluation of the specimen reported to be a mucocele with mucinous cystadenoma with negative surgical margins. The patient was discharged postoperative 6th day, and a control colonoscopy and abdominal CT was planned for 6 months following surgery. Appendicular mucocele is rare and difficult to diagnose preoperatively, and sometimes it may be of large size which increases the risk of perforation. Pseudomyxoma peritonei (PP) is the most feared complication of mucocele perforation. Appendectomy with negative margins is a requirement for adequate treatment for most cases. Utmost care should be taken during surgery to avoid perforation of mucocele. Sertkaya M, Emre A, Pircanoglu EM, Peker O, Cengiz E, Karaagaç M. Giant Appendicular Mucocele Due to Mucinous Cystadenoma.

In 2000, the Centers for Medicare & Medicaid Services announced a plan to allow for enhanced reimbursement for office endoscopy. This change in reimbursement was phased in during three years. The purpose of this study was to evaluate the fiscal outcomes and quality measures in the first two and a one-half years of performing endoscopy in an office setting under the new Centers for Medicare & Medicaid Services guidelines. The following financial parameters were gathered: number of endoscopies, expenses (divided into salaries and operational), net revenue, and margin for endoscopies performed in the office compared with the hospital. All endoscopies were performed by endoscopists with advanced training (gastroenterology fellowship or colon and rectal surgery residency). Monitoring equipment included continuous SaO2 and automated blood pressure in all patients and continuous electrocardiographic monitors in selected patients. Quality/safety data have been tracked in a prospective manner and include number of transfers to the hospital, perforations, bleeding requiring transfusion or hospitalization, and cardiorespiratory arrest. The financial outcomes are as follows: 13,285 endoscopies performed from the opening of the unit through December 2003; net revenue per case $504 per case; expense per case has dropped from $205 per case to $145 per case; the overall financial benefit of performing endoscopy in the office compared with the hospital was an additional $28 to $143 per case depending on the insurance carrier. The quality outcomes since inception of the unit include the following: 13,285 endoscopies; 0 hospital transfers, 0 cardiorespiratory arrests; 0 perforations; and 1 bleeding episode that required hospitalization. Endoscopy performed in the office setting is safe when done with appropriate monitoring and in the proper patient population. At the time of this study, office endoscopy also is financially rewarding but changes in Centers for Medicare & Medicaid Services reimbursement threaten the ability to retain any financial benefit.

Lower Extremity Free Flaps for Breast Reconstruction.

Dayan, Joseph H; Allen, Robert J

2017-11-01

Thigh-based flaps are typically a secondary option for breast reconstruction because of concerns regarding limited tissue volume and donor-site morbidity. In recent years, there have been a number of new techniques and insights that have resulted in greater flexibility and improved outcomes. This article reviews lessons learned from a large collective experience using the following 4 flaps: transverse upper gracilis also known as transverse myocutaneous gracilis, diagonal upper gracilis, profunda artery perforator, and lateral thigh perforator flaps. Flap selection considerations include the patient's fat distribution and skin laxity, perforator anatomy, and scar location. Pearls to minimize donor-site morbidity include avoiding major lymphatic collectors in the femoral triangle and along the greater saphenous vein and respecting the limits of flap dimension to reduce wound healing complications and distal ischemia. Limited flap volume may be addressed with stacking another flap from the contralateral thigh or primary fat grafting as opposed to overaggressive flap harvest from a single thigh. A detailed review of the benefits and disadvantages of each flap and strategies to improve results is discussed. With careful planning and selection, thigh-based flaps can provide a reliable option patients desiring autologous breast reconstruction.

Apparatus for taking a multiple of samples of groundwater or pressure measurements from a well simultaneously. The apparatus comprises a series of chambers arranged in an axial array, each of which is dimensioned to fit into a perforated well casing and leave a small gap between the well casing and the exterior of the chamber. Seals at each end of the container define the limits to the axial portion of the well to be sampled. A submersible pump in each chamber pumps the groundwater that passes through the well casing perforations into the gap from the gap to the surface for analysis. The power lines and hoses for the chambers farther down the array pass through each chamber above them in the array. The seals are solid, water-proof, non-reactive, resilient disks supported to engage the inside surface of the well casing. Because of the modular design, the apparatus provides flexibility for use in a variety of well configurations.

The conventional procedure of the sural neuro-fasciocutaneous flap enables the supply of blood and venous drainage by increasing the width of the adipofascial tissue and preserving tiny venous return routes. Moreover, skin graft is a common method for donor site closure, which may lead to some complications and influence the aesthetic appearance. We report modifications for a distally based sural neuro-fasciocutaneous perforator flap and a relaying flap for donor site closure without skin graft. Twelve patients undergoing the modified flap for foot and ankle reconstruction were included in this study between 2014 and 2016. A peroneal-based perforator, a superficial vein, and the vascular axis of the sural nerve were included in the pedicle. A Z-shape skin incision was performed to explore the perforator vessels and a relaying island perforator flap was used to close the donor site. All flaps survived completely without necrosis. The area of the flaps ranged from 16 × 8 cm to 30 × 15 cm. The diameter width of the pedicle ranged from 1.0 to 2.0 cm. A relaying perforator island flap was used in 10 cases for donor site closure and no skin graft was performed. There were no serious donor site complications. All patients were satisfied with the aesthetic outcome postoperatively at the final follow-up. The distally based sural neuro-fasciocutaneous perforator flap is considered a reliable method for foot and ankle reconstruction. The modification for flap pedicle and donor site closure method without skin graft should be recommended. Copyright © 2017. Published by Elsevier Ltd.

Defects after soft tissue sarcoma resection are usually managed by myocutaneous flaps or free flaps. However, harvesting muscle will cause functional morbidities, and some regions lack reliable recipient vessel. Our purpose is to use various perforator propeller flaps for oncologic reconstruction. Between 2008 and 2014, 33 perforator propeller flaps were performed in 24 patients to reconstruct the defects after tumor resection in trunk and extremities. Fifteen patients underwent tumor resection previously. Thirteen patients underwent adjuvant radiotherapy or chemotherapy. Flaps based on perforators adjacent to the lesions were raised and rotated in propeller fashion to repair the defects. Twenty-seven flaps were based on perforators of known source vessels, and 6 were harvested in freestyle fashion. The defects were repaired with 2 flaps in 4 patients and 3 flaps in 2 patients. The mean skin paddle dimension was 8.36 cm in width and 20.42 cm in length. The mean degree of flap rotation was 158.79°. Complications include partial necrosis of 6 flaps in 5 cases and venous congestion of 1 flap. In these 6 patients, 3 underwent adjuvant radiotherapy. The donor sites were primarily closed in 21 patients and skin grafted in 3 patients. No functional loss related to flap harvesting was recognized. The perforator propeller flaps can be used to manage the medium defects in extremities and large defects in torso after soft tissue sarcoma resection. They avoid the sacrifice of the underlying muscle and eliminate the concerns of the unavailability of recipient vessels. The perforator propeller flaps provide flexible options for versatile oncologic reconstruction in trunk and extremities. However, the impact of radiotherapy on the viability of the flaps for local reconstruction needs further investigation.

Perforated gastric ulcers are potentially complicated surgical emergencies and appropriate early management is essential in order to avoid subsequent problems including unnecessary gastrectomy. The aim of this study was to examine the management and outcome of patients with gastric ulcer perforation undergoing emergency laparotomy for peritonitis. Patients undergoing laparotomy at the Royal Infirmary of Edinburgh for perforated gastric ulcers were identified from the prospectively maintained Lothian Surgical Audit (LSA) database over the five-year period 2007-2011. Additional data were obtained by review of electronic records and review of case notes. Forty-four patients (25 male, 19 female) were identified. Procedures performed were: 41 omental patch repairs (91%), 2 simple closures (4.5%) and 2 distal gastrectomies (4.5%; both for large perforations). Four perforated gastric tumours were identified (8.8%), 2 of which were suspected intra-operatively and confirmed histologically, 1 had unexpected positive histology and 1 had negative intra-operative histology, but follow-up endoscopy confirmed the presence of carcinoma (1 positive biopsy in 21 follow-up endoscopies); all 4 were managed without initial resection. Median length of stay was 10 days (range 4-68). Overall 7 patients died in hospital (15.9%) and there were 21 morbidities (54.5%). Registrars performed the majority of the procedures (16 alone, 21 supervised) with no significant difference in post-operative morbidity (P = 0.098) or mortality (P = 0.855), compared to consultants. Almost all perforated gastric ulcers can be effectively managed by laparotomy and omental patch repair. Initial biopsy and follow-up endoscopy with repeat biopsy is essential to avoid missing an underlying malignancy. Copyright © 2013 Surgical Associates Ltd. Published by Elsevier Ltd.

The "chimeric" trapezius muscle and fasciocutaneous flap (dorsal scapular artery perforator flap): a new design for complex 3-dimensional defects.

PubMed

Rozen, Warren M; Fox, Carly M; Leong, James; Morsi, Adel

2013-11-01

Multiple variations of the musculocutaneous trapezius flap have been described, each of which use a single composite musculocutaneous unit in their designs. The limitation of such designs is the ability to use the components in a 3-dimensional manner, with only 1 vector existing in the geometry of the musculocutaneous unit. A review of the literature was undertaken with regard to designs of the musculocutaneous trapezius flap, and we present a new technique for flap design. With identification of individual perforators to each of the muscle and fasciocutaneous portions of the trapezius flap, the 2 components can act in a chimeric fashion, able to fill both a deep and complex 3-dimensional space while covering the wound with robust skin. A range of flap designs have been described, including transverse, oblique, and vertical skin paddles accompanying the trapezius muscle. We describe a technique with which a propeller-style skin paddle based on a cutaneous perforator can be raised in any orientation with respect to the underlying muscle. In a presented case, separation of the muscular and fasciocutaneous components of the trapezius flap was able to obliterate dead space around exposed cervicothoracic spinal metalwork and obtain robust wound closure in a patient with previous radiotherapy. This concomitant use of a muscle and fasciocutaneous perforator flap based on a single perforator, a so-called chimeric perforator flap, is a useful modification to trapezius musculocutaneous flap design.

Rare occupational cause of nasal septum perforation: Nickel exposure.

Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis), some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine). Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium), it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6):963-967.

The accuracy of pedicle screw placement was evaluated in posterior scoliosis surgeries with or without the use of computer-assisted surgical techniques. In this retrospective cohort study, the pedicle screw placement accuracy in posterior scoliosis surgery was compared between conventional fluoroscopic and computer-assisted surgical techniques. There has been no study systemically analyzing the perforation pattern and comparative accuracy of pedicle screw placement in posterior scoliosis surgery. The 45 patients who received posterior correction surgeries were divided into 2 groups: Group C, manual control (25 patients); and Group N, navigation surgery (20 patients). The average Cobb angles were 73.7 degrees and 73.1 degrees before surgery in Group C and Group N, respectively. Using CT images, vertebral rotation, pedicle axes as measured to anteroposterior sacral axis and vertebral axis, and insertion angle error were measured. In perforation cases, the angular tendency, insertion point, and length abnormality were evaluated. The perforation was observed in 11% of Group C and 1.8% in Group N. In Group C, medial perforations of left screws were demonstrated in 8 of 9 perforated screws and 55% were distributed either in L1 or T12. The perforation consistently occurred in pedicles in which those axes approached anteroposterior sacral axis within 5 degrees . The average insertion errors were 8.4 degrees and 5.0 degrees in Group C and Group N, respectively, which were significantly different (P < 0.02). The medial perforation in Group C occurred around L1, especially when pedicle axis approached anteroposterior sacral axis. This consistent tendency was considered as the limitation of fluoroscopic screw insertion in which horizontal vertebral image was not visible. The use of surgical navigation system successfully reduced the perforation rate and insertion angle errors, demonstrating the clear advantage in safe and accurate pedicle screw placement of scoliosis surgery.

Several risk factors for pacemaker (PM) related complications have been reported. However, no study has investigated the impact of lead characteristics on pacemaker-related complications. Patients who received a new pacemaker implant from January 1997 to December 2011 were selected from the Taiwan National Health Insurance Database. This population was grouped according to the pacemaker lead characteristics in terms of fixation and insulation. The impact of the characteristics of leads on early heart perforation was analyzed by multivariable logistic regression analysis, while the impact of the lead characteristics on early and late infection and late heart perforation over a three-year period were analyzed using Cox regression. This study included 36,104 patients with a mean age of 73.4±12.5 years. In terms of both early and late heart perforations, there were no significant differences between groups across the different types of fixation and insulations. In the multivariable Cox regression analysis, the pacemaker-related infection rate was significantly lower in the active fixation only group compared to either the both fixation (OR, 0.23; 95% CI, 0.07-0.80; P = 0.020) or the passive fixation group (OR, 0.26; 95% CI, 0.08-0.83; P = 0.023). There was no difference in heart perforation between active and passive fixation leads. Active fixation leads were associated with reduced risk of pacemaker-related infection.

Introduction Ingestion of foreign bodies has been previously reported in some patients with schizophrenia. This behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. Case Presentation This paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon inside his abdomen that he believed was controlling him. As a result, he developed an acute intestinal perforation and underwent surgery. Conclusions It is of a great importance to closely monitor the therapy compliance of patients suffering from mental illnesses. This will benefit them by preventing some of the serious complications of their disease, which may include life-threatening conditions such as intestinal perforation that needs surgical intervention.

The urethra is a usual site of introduction of foreign bodies for autoerotic stimulation. We present an unusual case of bladder perforation caused by foreign body that was self-inserted in the urethra and consequently slipped inside the bladder in a 29-year-old female patient with psychiatric disease. The patient was referred to our department for macroscopic hematuria and abdominal pain. Imaging studies revealed the presence of a foreign body in the pelvic area which had perforated the left lateral wall of the bladder. The foreign body was removed via open cystotomy. In psychiatric patients hematuria and pelvic pain may result from insertion of a foreign body in the bladder usually during masturbation.

Since urethral Foley catheterization is usually easy and safe, serious complications related to this procedure have been rarely reported. Herein, we describe a case of intraperitoneally placed urethral catheter via verumontanum presenting as intraperitoneal bladder perforation in a chronically debilitated elderly patient. A 82-yr-old male patient was admitted with symptoms of hematuria, lower abdominal pain after traumatic Foley catheterization. The retrograde cystography showed findings of intraperitoneal bladder perforation, but emergency laparotomy with intraoperative urethrocystoscopy revealed a tunnel-like false passage extending from the verumontanum into the rectovesical pouch between the posterior wall of the bladder and the anterior wall of the rectum with no bladder injury. The patient was treated with simple closure of the perforated rectovesical pouch and a placement of suprapubic cystostomy tube.

Lower third leg soft tissue defects with anatomical and pathological constraints are posing formidable challenges to reconstructive surgeon. This retrospective study was conducted to assess the effectiveness of ad hoc posterior tibial vessels perforator-propeller flaps for the reconstruction of small and medium sized soft tissue defects in the lower third leg. 22 patients (16 were males and 6 were females) were involved in this study between period of January 2012 and December 2016.We followed the protocol of initial non delineating exploratory incision made to find out single best perforator in all patients. All the defects in leg reconstructed with adhoc posterior tibial vessel propeller flaps. All 22 flaps survived well. All in an average of 13 months follow up period, had pain free walking, with minimal scarring and acceptable aesthesis at the reconstruction sites with no need for any secondary procedure. With inability of preoperatively dopplering the perforators in the lower third leg region, the exploratory posterior nondelineating incision was used in all cases to secure the single best perforator for the propeller flaps. Thus adhoc posterior tibial vessel propeller flaps are dependable, easily adoptable for the reconstruction of soft tissue defects of the lower third leg region.

We present a new surgical modification to allow propeller perforator flaps to cover pressure sores at various locations. We used a propeller perforator flap concept based on the detection of newly formed perforator vessels located 1 cm from the wound margin and stimulated by the chronic inflammation process. Between January 2009 and January 2017, 33 wound edge-based propeller perforator flaps were used to cover pressure sores at various locations in 28 patients. In four cases more than one flap was used on the same patient. The patients comprised 18 males and 10 females with a mean age of 41·25 (range, 16-70) years. All patients underwent follow-up for 0-12 months. The mean follow-up duration was 5·03 months. Venous congestion was observed in three flaps that were rotated by 180° (9·1%). However, there was a significant difference between flaps rotated by 90° and 180° according to the complication rate (P = 0·034). Out of 33 flaps, 29 flaps healed uneventfully. Patients were able to sit and lie on their flaps three weeks after surgery. In our study, we were able to obtain satisfying final results using these novel flaps. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

The role of metallic stents in the palliation of esophageal cancer is well established. Self-expanding metal stents (SEMSs) are frequently used, as they provide an effective and safe method of relieving malignant dysphagia. A number of complications are associated with the use of SEMSs, including esophageal perforation. We report a case of thoracic discitis occurring in a patient with advanced esophageal malignancy, treated with SEMSs. We propose that the likely etiology in this patient was esophageal perforation by a metallic stent.

We reviewed 30 cases of osteochondral lesions of the astragalar vault treated surgically. Among the 30 patients, 17 participated in sports activities and 24 had a history of trauma. Mean delay to surgery was 10 months. Treatment included osteochondritis curettage and Pridie perforations. Direct access was used in 11 cases, malleolar osteotomy in 13 and arthroscopy in 6. Cancellous bone grafts were used in 6 cases. Mean follow-up was 3 years 7 months (minimum 2 years). All patients had an arthroscan at last follow-up. Evaluation of post-operative outcome was based on clinical assessment and arthroscan findings. Surgical treatment provided very good results in 75 p. 100 of cases with pain relief and improved walking distance. Our cases pointed out the important contribution of the FOG (Fracture Osteonecrosis Geode) classification to pathogenic and prognostic analysis. The Berndt and Harty classifications were not found to be useful. In case of localized necrosis, we propose arthroscopic perforation curettage. In case of bone loss, a direct cancellous graft may be used.

2016-12-01

We report a case of a rare complication of acute appendicitis with perforation through the abdominal wall. The case points out that an intraabdominal origin should be considered in patients presenting with rapidly spreading soft tissue infections of the trunk. A 58-year-old European woman presented to our hospital with a 1-week history of severe abdominal pain accompanied by rapidly spreading erythema and emphysema of the lower abdomen. On admission, the patient was in septic shock with leukocytosis and elevation of C-reactive protein. Among other diagnoses, necrotizing fasciitis was suspected. Computed tomography showed a large soft tissue infection with air-fluid levels spreading through the lower abdominal wall. During the operation, we found a perforated appendicitis breaking through the fascia and causing a rapidly progressive soft tissue infection of the abdominal wall. Appendicitis was the origin of the soft tissue infection. The abdominal wall was only secondarily involved. Even though perforated appendicitis as an etiology of a rapidly progressive soft tissue infection of the abdominal wall is very rare, it should be considered in the differential diagnosis of abdominal wall cellulitis. The distinction between rapidly spreading subcutaneous infection with abscess formation and early onset of necrotizing fasciitis is often difficult and can be confirmed only by surgical intervention.

Acute pseudo-obstruction of the colon is a disorder characterised by an increase in intra-luminal pressure that leads to ischaemia and necrosis of the intestinal wall. The mechanism that produces the lesion is unknown, although it has been associated with: trauma, anaesthesia, or drugs that alter the autonomic nervous system. The pathophysiology of medication induced colon toxicity can progress to a perforated colon and potentially death. Present a case of a colonic pseudo-obstruction in a patient with polypharmacy as the only risk factor and to review the medical literature related to the treatment of this pathology. The case is presented of a 67 year old woman with colonic pseudo-obstruction who presented with diffuse abdominal pain and distension. The pain progressed and reached an intensity of 8/10, and was accompanied by fever and tachycardia. There was evidence of free intraperitoneal air in the radiological studies. The only risk factor was the use of multiple drugs. The colonic pseudo-obstruction progressed to intestinal perforation, requiring surgical treatment, which resolved the problem successfully. It is important to consider drug interaction in patients with multiple diseases, as it may develop complications that can be avoided if detected on time.

2010-06-01

We present a case of neonatal ovarian torsion complicated by bowel obstruction and perforation and review the literature regarding the incidence of bowel obstruction in neonatal ovarian cysts, the presentation, and treatment. A term neonate was prenatally diagnosed with a cystic abdominal mass palpable on physical examination. A postnatal abdominal x-ray showed paucity of gas in the left hemiabdomen with rightward displacement of bowel loops. Exploratory laparotomy on day 2 of life revealed a large cystic mass in the left lower quadrant consistent with a torsed left ovary, an omental band causing strangulation of the bowel mesentery, and a perforation of the distal ileum. Our literature search revealed 19 reported cases of neonatal ovarian cysts resulting in bowel obstruction. Infants may present with a palpable abdominal mass, respiratory distress, as well as signs and symptoms of intestinal obstruction. Two mechanisms exist for bowel obstruction: adhesions caused by a torsed necrotic ovary and mass effect of a large ovarian cyst, often measuring 9 to 10 cm in diameter. Options to treat ovarian cysts include antenatal or postnatal aspiration, laparoscopy, and laparotomy.

Summary Perforated peptic ulcer (PPU) is a frequent emergency condition worldwide with associated mortality up to 30%. A paucity of studies on PPU limits the knowledge base for clinical decision-making, but a few randomised trials are available. While Helicobacter pylori and use of non-steroidal anti-inflammatory drugs are frequent causes of PPU, demographic differences in age, gender, perforation location and aetiology exist between countries, as do mortality rates. Clinical prediction rules are used, but accuracy varies with study population. Early surgery, either by laparoscopic or open repair, and proper sepsis management are essential for good outcome. Selected patients can perhaps be managed non-operatively or with novel endoscopic approaches, but validation in trials is needed. Quality of care, sepsis care-bundles and postoperative monitoring need further evaluation. Adequate trials with low risk of bias are urgently needed for better evidence. Here we summarize the evidence for PPU management and identify directions for future clinical research. PMID:26460663

In line with advances in diagnostic methods and expectation of a decrease in the number of negative laparotomies, selective non-operative management of abdominal gunshot wounds has been increasingly used over the last three decades. We aim to detect the possibility of treatment without surgery and present our experience in selected cases referred from Syria to a hospital at the Turkish-Syrian border. Between February 2012 and June 2014, patients admitted with abdominal gunshot wounds were analyzed. Computed tomography was performed for all patients on admission. Patients who were hemodynamically stable and did not have symptoms of peritonitis at the time of presentation were included in the study. The primary outcome parameters were mortality and morbidity. Successful selective non-operative management (Group 1) and unsuccessful selective non-operative management (Group 2) groups were compared in terms of complications, blood transfusion, injury site, injury severity score (ISS), and hospital stay. Of 158 truncal injury patients, 18 were considered feasible for selective non-operative management. Of these, 14 (78%) patients were treated without surgery. Other Four patients were operated upon progressively increasing abdominal pain and tenderness during follow-up. On diagnostic exploration, all of these cases had intestinal perforations. No mortality was observed in selective non-operative management. There was no statistically significant difference between Group 1 and Group 2, in terms of length of hospital stay (96 and 127 h, respectively). Also, there was no difference between groups in terms of blood transfusion necessity, injury site, complication rate, and injury severity score (p>0.05). Decision making on patient selection for selective non-operative management is critical to ensure favorable outcomes. It is not possible to predict the success of selective non-operative management in advance. Cautious clinical examination and close monitoring of these patients is vital; however, emergency laparotomy should be performed in case of change in vital signs and positive symptoms concerning peritonitis.

To assess the risk of gastrointestinal perforation, ulcers, or bleeding (PUB) associated with the use of conventional nonsteroidal anti-inflammatory drugs (NSAIDs) with proton pump inhibitors (PPIs) and selective COX-2 inhibitors, with or without PPIs compared with conventional NSAIDs. A case-control study was performed within conventional NSAIDs and/or selective COX-2 inhibitors users identified from the Dutch PHARMO Record Linkage System in the period 1998-2012. Cases were patients aged ≥18 years with a first hospital admission for PUB. For each case, up to four controls were matched for age and sex at the date a case was hospitalized (index date). Logistic regression analysis was used to calculate odds ratios (ORs). At the index date, 2634 cases and 5074 controls were current users of conventional NSAIDs or selective COX-2 inhibitors. Compared with conventional NSAIDs, selective COX-2 inhibitors with PPIs had the lowest risk of PUB (adjusted OR 0.51, 95% confidence interval [CI]: 0.35-0.73) followed by selective COX-2 inhibitors (adjusted OR 0.66, 95%CI: 0.48-0.89) and conventional NSAIDs with PPIs (adjusted OR 0.79, 95%CI: 0.68-0.92). Compared with conventional NSAIDs, the risk of PUB was lower for those aged ≥75 years taking conventional NSAIDs with PPIs compared with younger patients (adjusted interaction OR 0.79, 95%CI: 0.64-0.99). However, those aged ≥75 years taking selective COX-2 inhibitors, the risk was higher compared with younger patients (adjusted interaction OR 1.22, 95%CI: 1.01-1.47). Selective COX-2 inhibitors with PPIs, selective COX-2 inhibitors, and conventional NSAIDs with PPIs were associated with lower risks of PUB compared with conventional NSAIDs. These effects were modified by age. © 2017 The Authors. Pharmacoepidemiology & Drug Safety Published by John Wiley & Sons Ltd. © 2017 The Authors.

This paper reports the CO2SINK drilling and permanent monitoring completions, as well as the well testing techniques applied in Europe's first scientific carbon dioxide onshore storage test in a saline aquifer near the town of Ketzin, 40 km east of Berlin/Germany. Three boreholes, one injection and two observation wells have been drilled in 2007 to a total depth of about 800 m. The wells were completed as "smart" wells containing a variety of permanently installed down-hole sensors, which have successfully proven their functionality during over their first injection year and are the key instruments for the continuous monitoring of the CO2 inside the reservoir during the storage phase. Constructing three wells in close proximity of 50 to 100m distance to each other with a dense sensor and monitoring cable population requires detailed planning and employment of high-end project management tools. All wells were cased with stainless final casings equipped with pre-perforated sand filters in the pay-zone and wired on the outside with two fibre-optical, one multi-conductor copper, and a PU-heating cable to the surface. The reservoir casing section is externally coated with a fibre-glass-resin wrap for electrical insulation of the 15 geo-electrical toroid antennas in the open hole section. A staged cementation program was selected in combination with the application of a newly developed swellable rubber packer technology and specialized cementation down-hole tools. This technology was given preference over perforation work inside the final casing at the reservoir face, which would have created unmanageable risks of potential damage of the outside casing cables. Prior to the start of the injection phase, an extensive production and injection well test program as well as well-to-well interference tests were performed in order to determine the optimum CO2 injection regime.

Complications at the gastrojejunal anastomosis after laparoscopic Roux-en-Y gastric bypass (LRYGB) are challenging in terms of diagnosis, therapy, and prevention. This study aims at identifying these complications and discussing their management. Data of 228 patients who underwent a LRYGB between October 2008 and December 2011 were reviewed retrospectively to evaluate the frequency and treatment of complications such as stenoses, marginal ulcers, perforated marginal ulcers, or anastomotic leaks related to the operation. Follow-up information was available for 209 patients (91.7%) with a median follow-up of 38 months (range 24-62 months). Of these patients 16 patients (7.7%) experienced complications at the gastrojejunostomy. Four patients (1.9%) had stenoses and 12 patients (5.7%) marginal ulcers, one of them with perforation (0.5%). No anastomotic leaks were reported. One case with perforated ulcer and one with recurrent ulcers required surgical revision. Gastrojejunal anastomotic complications are frequent and occur within the first few days or up to several years after surgery. Stenoses or marginal ulcers are usually successfully treated nonoperatively. Laparoscopic repair, meanwhile, is an appropriate therapeutic option for perforated ulcers.

The regular colonisation of the oesophagus with a Candida species can, after oesophageal perforation, result in a contamination of the mediastinum and the pleura with a Candida species. A patient cohort of 80 patients with oesophageal perforation between 1986 and 2010 was analysed retrospectively. The most common sources with positive results for Candida were mediastinal biopsies and broncho-alveolar secretions. Candida species were detected in 30% of the patients. The mortality rate was 41% in patients with positive microbiology results for Candida, whereas it was 23% in the remaining patient cohort. This difference did not reach statistical significance (P = 0.124). Mortality associated with oesophageal perforation was attributed mainly to septic complications, such as mediastinitis and severe pneumonia. During the study period we observed a shift towards non-albicans species that were less susceptible or resistant to fluconazole. In selected patients with risk factors as immunosuppression, granulocytopenia and long-term intensive-care treatment together with the finding of Candida, an antimycotic therapy should be started. A surgical approach offers the possibility to obtain deep tissue biopsies. The antimycotic therapy should start with an echinocandin, as the resistance to fluconazole is growing and to cover non-albicans Candida species, too. © 2012 Blackwell Verlag GmbH.

Psoas tunnel perforation—an unreported complication of hip arthroscopy

PubMed Central

Degen, Ryan M.; O’Sullivan, Eilish; Sink, Ernest L.; Kelly, Bryan T.

2015-01-01

The utilization of hip arthroscopy is rapidly increasing due to improved arthroscopic techniques and training, better recognition of pathology responsible for non-arthritic hip pain and an increasing desire for minimally invasive procedures. With increasing rates of arthroscopy, associated complications are also being recognized. We present a series of six patients who experienced psoas tunnel perforation during anchor insertion from the distal anterolateral portal during labral repair. All patients underwent prior hip arthroscopy and labral repair and presented with persistent symptoms at least partly attributable to magnetic resonance imaging (MRI)-documented psoas tunnel perforation. Their clinical records, operative notes and intra-operative photographs were reviewed. All patients presented with persistent pain, both with an anterior impingement test and resisted hip flexion. MRI imaging demonstrated medial cortical perforation with anchors visualized in the psoas tunnel, adjacent to the iliopsoas muscle. Four patients have undergone revision hip arthroscopy, whereas two have undergone periacetabular osteotomies. All patients had prominent anchors in the psoas tunnel removed at the time of surgery, with varying degrees of concomitant pathology appropriately treated during the revision procedure. Care must be utilized during medial anchor placement to avoid psoas tunnel perforation. Although this complication alone was not the sole cause for revision in each case, it may have contributed to their poor outcome and should be avoided in future cases. This can be accomplished by using a smaller anchor, inserting the anchor from the mid-anterior portal and checking the drill hole with a nitinol wire prior to anchor insertion. PMID:27011849

The opinion, that the use of foil reactors for the aerobic biostabilization of municipal wastes is not a valid method, due to vulnerability to perforation, and risk of uncontrolled release of exhaust gasses, was verified. This study aimed to determine the intensity of greenhouse gas (GHG) emissions to the atmosphere from the surface of foil reactors in relation to the extent of foil surface perforation. Three scenarios were tested: intact (airtight) foil reactor, perforated foil reactor, and torn foil reactor. Each experimental variant was triplicated, and the duration of each experiment cycle was 5 weeks. Temperature measurements demonstrated a significant decrease in temperature of the biostabilization in the torn reactor. The highest emissions of CO 2 , CO and SO 2 were observed at the beginning of the process, and mostly in the torn reactor. During the whole experiment, observed emissions of CO, H 2 S, NO, NO 2 , and SO 2 were at a very low level which in extreme cases did not exceed 0.25 mg t -1 .h -1 (emission of gasses mass unit per waste mass unit per unit time). The lowest average emissions of greenhouse gases were determined in the case of the intact reactor, which shows that maintaining the foil reactors in an airtight condition during the process is extremely important.

To report rapid corneal thinning and perforation in a case with relapsing polychondritis. A 43 year-old male diagnosed with relapsing polychondritis suffered from bilateral scleritis, bilateral swelling of pinna, saddle nose and tracheal stenosis. The patient presented with right eye pain and redness for one month. Slit lamp examination of the right eye showed 80% peripheral corneal thinning between 3 and 7 o'clock. The best-corrected visual acuity (BCVA) was 1.0 bilaterally. The degree of corneal thinning worsened to 90% after one week of oral corticosteroid use. Subsequently, topical cyclosporine 2% eye drops four times a day, oral doxycycline 100 mg twice a day and oral vitamin C 2 g daily were added. The corneal thinning gradually improved to about 60%. However, the patient rapidly tapered oral prednisolone against medical advice and returned with an acute drop in vision in his right eye. Slit lamp examination of the right eye showed peripheral corneal perforation with iris prolapse. An emergency repair with cyanoacrylate glue was performed. Intravenous methylprednisolone 1 mg/kg body weight was administered for three days and 1 g/day intravenous immunoglobulin was administered every four weeks. At 3 months postoperatively, BCVA in the right eye was 0.6. Slit lamp examination showed a well-formed anterior chamber with glue in situ. Relapsing polychondritis may be associated with rapid corneal thinning. The clinicians should be aware of the possibility of corneal perforation in these cases. Cyanoacrylate glue is a viable temporary management option in such scenarios.

Currently, increased interest in the perforator-pedicled propeller flap should not obscure the fact that it is, in reality, a complex procedure requiring experience and monitoring similar to free flaps. Through a meta-analysis, the authors aimed to identify the risk factors of perforator-pedicled propeller flap failure in lower extremity defects. The MEDLINE, PubMed Central, Embase, and Cochrane databases were searched from 1991 to May of 2014 for articles describing perforator-pedicled propeller flaps in the lower extremity. The study selection met the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fixed-effects models were used. Forty articles complied with the inclusion criteria, representing 428 perforator-pedicled propeller flaps. The most common cause was posttraumatic (55.2 percent). Most of the defects were at the distal third of the lower leg (45.6 percent). The arc of rotation was 180 degrees for 34.3 percent. Complications were found in 25.2 percent, including partial necrosis (10.2 percent) and complete necrosis (3.5 percent). Complete flap survival was found in 84.3 percent. The authors identified three significant risk factors: age older than 60 years (relative risk, 1.61; p = 0.03), diabetes (relative risk, 2.00; p = 0.02), and arteriopathy (relative risk, 3.12; p = 0.01). No significant results were found regarding smoking status other than a tendency (p = 0.06), acute cause (p = 0.59), posttraumatic cause (p = 0.97), distal third of the lower leg (p = 0.66), fascia inclusion (p = 0.70), and pedicle rotation greater than 120 degrees (p = 0.41). Age older than 60 years, diabetes, and arteriopathy are significant risk factors of perforator-pedicled propeller flap complications in the lower extremity. Risk, IV.

Method of making an ion beam sputter-etched ventricular catheter for hydrocephalus shunt

Banks, B. A. (Inventor)

1984-01-01

The centricular catheter comprises a multiplicity of inlet microtubules. Each microtubule has both a large opening at its inlet end and a multiplicity of microscopic openings along its lateral surfaces. The microtubules are perforated by an ion beam sputter etch technique. The holes are etched in each microtubule by directing an ion beam through an electro formed mesh mask producing perforations having diameters ranging from about 14 microns to about 150 microns. This structure assures a reliable means for shunting cerebrospinal fluid from the cerebral ventricles to selected areas of the body.

Since the end of the nineties endovenous thermal ablation and more recently non-thermal, non-tumescent techniques have been developed and improved. Until now, because of their favourable side effect profile in conjunction to sustained efficacy, in many countries they already replaced high ligation and stripping in the treatment of refluxing saphenous veins as well as for treatment of perforators and selected tributaries. Now, studies and comparative trials are available with long-term follow-ups for most of the techniques, providing valid data on occlusion and reflux rates, side effect profiles, and health related quality of life.

A system for inducing implosion shock forces on perforation traversing earth formations with fluid pressure where an implosion tool is selected relative to a shut in well pressure and a tubing pressure to have a large and small area piston relationship in a well tool so that at a predetermined tubing pressure the pistons move a sufficient distance to open an implosion valve which permits a sudden release of well fluid pressure into the tubing string and produces an implosion force on the perforations. A pressure gauge on the well tool records tubing pressure and well pressure as a function of time.

Pancreaticoduodenectomy is a demanding procedure even in selected patients but becomes formidable when performed in cases of emergency. This study analyzed our experience with urgent pancreatoduodenectomies; special emphases were put on the evaluation of diagnostic means and the validation of existing indications for performance of this procedure. Three hundred one patients who underwent pancreatoduodenectomy between 1989 and 2008 were identified from a pancreatic resection database and reviewed for emergency indications. Six patients (2%) underwent emergency pancreatoduodenectomy. Indications included endoscopy-related perforation, postoperative complications, and uncontrollable intraduodenal tumor bleeding. Length of stay and occurrence of nonsurgical complications were increased in emergency compared with elective pancreatoduodenectomies. Although increased, no significant differences were found regarding mortality and surgery-related complications. Indications for emergency pancreatoduodenectomies were based on clinical decisions rather than on radiologic diagnostics. Urgent pancreatic head resections may be considered as an option in selected patients if handling of local complications by interventional measures or limited surgery seems unsafe.

Abstract The aim of this study was to evaluate the efficacy of combined therapy with metronidazole and broad-spectrum antibiotics for patients with perforated appendicitis who underwent surgical intervention. Broad-spectrum antibiotic therapy is warranted in the treatment of perforated appendicitis. Metronidazole has been used as anaerobic antimicrobial therapy. However, few studies about the use of metronidazole in perforated appendicitis have been reported. The medical records of 249 patients treated with metronidazole combined with broad-spectrum antibiotics following perforated appendicitis surgery were reviewed retrospectively and compared with the medical records of 149 patients treated only with broad-spectrum antibiotics. Propensity score matching was performed to adjust for selected baseline variables. Clinical outcomes, including postoperative complications and length of hospital stay, were compared between the 2 groups. No differences were found between the use of combined therapy with metronidazole and the use of solely broad-spectrum antibiotic agents with regard to postoperative duration of intravenous antibiotic treatment (6.8 ± 1.3 vs 7.9 ± 2.1 days, respectively, P = .18), inflammation variables at POD 5 (white blood cell [WBC] [risk ratio [RR], 1.06; 95% confidence interval [CI], 0.67–1.93, P = .15] and C-reactive protein [CRP] [RR, 1.18; 95% CI, 0.73–2.25, P = .36]) (Table 2), and the mean postoperative length of hospital stay (LOS) (RR, 0.68, 95% CI, 0.41–0.94, P = .41). There were also no differences in the incidence of postoperative complications, including the intra-abdominal or pelvic abscess rate (7[7.1%] vs 9[9.2%], respectively, P = .40), the incidence of wound infection (14[14.3%] vs 15[15.3%], respectively, P = .50), and the 30-day readmission rate (9[9.2%] vs 12[12.2%], respectively, P = .32). Regarding overall postoperative outcomes and complications, our study demonstrated no beneficial clinical effects of metronidazole administration in patients with perforated appendicitis who underwent surgical intervention. Therefore, metronidazole is not indicated when broad-spectrum antibiotics such as aminopenicillins with β-lactam inhibitors or carbapenems and select cephalosporins are used. PMID:29381994

We report an extremely rare case of complicated Amyand's hernia. A 61-year-old male patient was admitted with clinical signs of incarcerated right inguinal hernia and localised tenderness in the right iliac fossa. He underwent emergency surgery and the operative findings included perforated appendix and periappendicular abscess within a right inguinal hernia sac. Appendectomy and Shouldice's herniorrhaphy without prosthetic mesh placement were performed. Histology revealed the presence of a villous adenoma near the base of the appendix. We point out that although Amyand's hernia is a very rare clinical entity, it should always be considered in the differential diagnosis in cases with clinical signs of incarcerated right inguinal hernia, especially when there are no pathological findings on the abdominal X-rays.

Unusual locations of the appendix vermiformis can result in delay in appropriate diagnosis and treatment of appendicitis. So an inflamed appendix in a sub-hepatic caecum caused by caecal maldescent for example can mimic cholecystitis, the pain being localized in the right upper quadrant. Here, we present a case of perforated sub-hepatic appendicitis with peritonitis, requiring open ileocaecal resection. Review of the existing literature has demonstrated that this pathology is uncommon, yet not so rare as one might presume. In conclusion, surgeons should be aware of this possibility in the diagnostic and therapeutic management of acute abdomen. Copyright © 2016. Published by Elsevier GmbH.

Acquired perforating dermatosis (APD) is an uncommon disease characterized by lesions exhibiting transepidermal elimination of collagen or elastic fibers. APD affects adults and is associated with systemic diseases, mainly diabetes mellitus and renal failure. We present 8 cases of APD. Seven patients had concomitant diabetes mellitus with or without chronic renal failure, and 1 had alcoholic cirrhosis. In the patients with chronic renal failure, the onset of APD coincided with transient worsening of renal function. The mean increase in creatinine concentrations above baseline was 1.14mg/dL. Acute deterioration of renal function may be involved in APD. Further studies are needed to investigate this association. Copyright © 2013 Elsevier España, S.L. y AEDV. All rights reserved.

Perforator Peroneal Artery Flap for Tongue Reconstruction.

Chauhan, Shubhra; Chavre, Sachin; Chandrashekar, Naveen Hedne; B S, Naveen

2017-03-01

Reconstruction has evolved long way from primary closure to flaps. As time evolved, better understanding of vascularity of flap has led to the development of innovative reconstructive techniques. These flaps can be raised from various parts of the body for reconstruction and have shown least donor site morbidity. We use one such peroneal artery perforator flap for tongue reconstruction with advantage of thin pliable flap, minimal donor site morbidity and hidden scar. Our patient 57yrs old lady underwent wide local excision with selective neck dissection. Perforators are marked about 10 and 15 cm inferiorly from the fibular head using hand held Doppler. Leg is positioned in such a way to give better exposure during dissection of the flap and flap is harvested under a tourniquet with pressure kept 350 mm Hg. The perforator is kept at the eccentric location, so as to gain length of the pedicle. Skin incison is placed over the peroneal muscle and deepened unto the deep facia, then the dissection is continued over the muscle and the perforator arising from the lateral septum. The proximal perforator about 10 cm from the fibular head is a constant perforator and bigger one, which is traced up to the peroneal vessel. We could get a 6 cm of pedicle length. Finally the flap is islanded on this perforator and the pedicle is ligated and flap harvested. Anastamosis was done to the ipsilateral side to facial vessels. The donor site is closed primarily and in the upper half one can harvest 5 cm width flap without requiring a skin graft along with a length of 8 to 12 cm. Various local and free flap has been used for reconstruction of partial tongue defects with its obvious donor site problems, like less pliable skin and not so adequate tissue from local flaps and sacrificing a important artery as in radial forearm flap serves as the work horse in reconstruction of partial tongue defects, Concept of super microsurgery was popularized by Japanese in 1980s and the concept of angiosome proposed by Taylor paved the way for development of new flaps. True perforator flaps are those where the source vessel is left undisturbed and overlying skin flap is raised. Yoshimura proposed cutaneous flap could be raised from peroneal artery (Br J Plast Surg 42:715-718, 1989). Wolff et al. (Plast Reconstr Surg 113:107-113, 2004) first used perforator based peroneal artery flap for oral reconstruction. Location of perforators vary, hence pre operative localisation can be done by ultrasound doppler, CT angio or MR angiography. Disadvantages over radial flap include varying anatomic location of perforators, need for imaging and difficult dissection of delicate vessels through muscles and hence a learning curve. Our patient had an arterial thrombus within few hours post-operatively which was successfully salvaged with immediate re-exploration and re-anastomosis of artery. Post-operative healing was uneventful and donor site was closed primarily without the need for graft. Perforator peroneal flap serves as a useful armamentarium for reconstruction of moderate size defects of tongue, buccal mucosa and floor of mouth with advantages of thin pliable flap, minimal donor site morbidity and hidden scar.

Liquid nitrogen ingestion leading to massive pneumoperitoneum without identifiable gastrointestinal perforation.

Liquid nitrogen (LN) ingestion is unusual, but may be encountered by poison centers, emergency physicians, and general surgeons. Unique properties of LN produce a characteristic pattern of injury. A 19-year-old male college student presented to the Emergency Department complaining of abdominal pain and "bloating" after drinking LN. His presentation vital signs were remarkable only for mild tachypnea and tachycardia. On physical examination, he had mild respiratory difficulty due to abdominal distention. His abdomen was tense and distended. Abdominal X-ray studies revealed a massive pneumoperitoneum. At laparotomy, he was found to have a large amount of peritoneal gas. No perforation was identified. After surgery, the patient made an uneventful recovery and was discharged 5 days later. At 2-week clinic follow-up, he was doing well without complications. Nitrogen is a colorless, odorless gas at room temperature. Due to its low boiling point (-195 degrees C), LN rapidly evaporates when in contact with body surface temperatures. Therefore, ingested LN causes damage by two mechanisms: rapid freezing injury upon mucosal contact and rapid volume expansion as nitrogen gas is formed. Patients who ingest LN may develop gastrointestinal perforation and massive pneumoperitoneum. Because rapid gas formation may allow large volumes to escape from tiny perforations, the exact site of perforation may never be identified. In cases of LN ingestion, mucosal injury and rapid gas formation can cause massive pneumoperitoneum. Although laparotomy is recommended for all patients with signs of perforation, the site of injury may never be identified. Copyright 2010 Elsevier Inc. All rights reserved.

Endoscopic dilation (ED) is used for the treatment of benign strictures caused by reflux esophagitis or anastomotic stenosis after esophagectomy. Esophageal stenosis is a major complication after endoscopic submucosal dissection (ESD) of large superficial esophageal cancer, but little is known regarding the incidence of complications of ED for stenosis caused by esophageal ESD. This was a retrospective study conducted at a single institution. From September 2002 to December 2012, a total of 1,337 ED procedures were performed for stenosis after esophageal ESD in 121 patients. The incidence of complications of ED and related clinical characteristics were analyzed. The incidence of bleeding was 0.8 % (1/121) per patient and 0.07 % (1/1,337) per procedure. The incidence of perforation was 4.1 % (5/121) per patient and 0.37 % (5/1,337) per procedure. Perforation occurred at a median of third time of ED procedures (range 2-9 procedures) and at a median of 18 days (range 8-29 days) after ESD. There were no significant characteristics correlated to perforation, such as location, circumferential extent, or diameter of mucosal defect after ESD. The total number of ED procedures was significantly larger among perforation cases (37, range 6-57) compared with those without perforation (7, range 1-70) (p = 0.01), and the treatment duration tended to be longer (190 vs. 69 days, respectively). The incidence of bleeding caused by ED for esophageal stenosis after ESD was very low. Relevant risk of perforation should be considered for patients requiring multiple ED procedures.

We report the case of a 45-year-old male patient who developed an acute peptic ulcer perforation of the tubal stomach on the second postoperative day after oesophagectomy. The patient underwent emergency surgery (perforation was closed with a Graham patch) followed by treatment in intensive care, and was finally discharged on the 19th postoperative day. Gastric pull-up is a surgical technique that is widely used to re-establish the continuity of the gastrointestinal tract after oesophagectomy. Various early and late complications of reconstruction with the tubal stomach are well-known, such as gastric necrosis, gastritis, gastric ulcer, as well as benign and malignant tumors. The precise etiology of gastric tube ulceration is not known yet, however, it can develop not only in the late, but also in the early postoperative period, as well.

Thyroid storm is a rare and life-threatening complication of thyrotoxicosis that requires prompt treatment. Thyroid storm is also known to be associated with precipitating events. The simultaneous treatment of thyroid storm and its precipitant, when they are recognized, in a patient is recommended; otherwise such disorders, including thyroid storm, can exacerbate each other. Here we report the case of a thyroid storm patient (a 55-year-old Japanese male) complicated with a perforated duodenal ulcer. The patient was successfully treated with intensive treatment for thyroid storm and a prompt operation. Although it is believed that peptic ulcer rarely coexists with hyperthyroidism, among patients with thyroid storm, perforation of a peptic ulcer has been reported as one of the causes of fatal outcome. We determined that surgical intervention was required in this patient, reported despite ongoing severe thyrotoxicosis, and reported herein a successful outcome.

An interesting case of a middle-aged woman who sustained oral lacerations and pharyngeal tear/perforation on opening a bottle of Lambrini sparkling wine with her teeth is presented. The patient presented to the Accident and Emergency (A&E) department with bleeding from the mouth and dyspnoea, and on examination had a neck surgical emphysema and visible laceration to the oropharynx. On further investigation, including a range of imaging modalities, a diagnosis of pharyngeal tear/perforation was made, detected on a gastrograffin swallow test. The patient was subsequently treated conservatively, being kept nil by mouth and fed through a nasogastric tube, with prophylactic antibiotic cover. The patient was re-imaged 1 week later, which displayed complete resolution of the tear, and was subsequently discharged on a normal oral diet. PMID:21853003

Salmonella enterica serovar Typhi (Salmonella Typhi) causes an estimated 22 million typhoid fever cases and 216 000 deaths annually worldwide. In Africa, the lack of laboratory diagnostic capacity limits the ability to recognize endemic typhoid fever and to detect outbreaks. We report a large laboratory-confirmed outbreak of typhoid fever in Uganda with a high proportion of intestinal perforations (IPs). A suspected case of typhoid fever was defined as fever and abdominal pain in a person with either vomiting, diarrhea, constipation, headache, weakness, arthralgia, poor response to antimalarial medications, or IP. From March 4, 2009 to April 17, 2009, specimens for blood and stool cultures and serology were collected from suspected cases. Antimicrobial susceptibility testing and pulsed-field gel electrophoresis (PFGE) were performed on Salmonella Typhi isolates. Surgical specimens from patients with IP were examined. A community survey was conducted to characterize the extent of the outbreak. From December 27, 2007 to July 30, 2009, 577 cases, 289 hospitalizations, 249 IPs, and 47 deaths from typhoid fever occurred; Salmonella Typhi was isolated from 27 (33%) of 81 patients. Isolates demonstrated multiple PFGE patterns and uniform susceptibility to ciprofloxacin. Surgical specimens from 30 patients were consistent with typhoid fever. Estimated typhoid fever incidence in the community survey was 8092 cases per 100 000 persons. This typhoid fever outbreak was detected because of an elevated number of IPs. Underreporting of milder illnesses and delayed and inadequate antimicrobial treatment contributed to the high perforation rate. Enhancing laboratory capacity for detection is critical to improving typhoid fever control.

Background/Aims Esophageal stricture is usually managed with outpatient endoscopic dilation. However, patients with food impaction or failure to thrive undergo inpatient dilation. Esophageal perforation is the most feared complication, and its risk in inpatient setting is unknown. Methods We used National Inpatient Sample (NIS) database for 2007–2013. International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM) codes were used to identify patients with esophageal strictures. Logistic regression was used to assess association between hospital/patient characteristics and utilization of esophageal dilation. Results There were 591,187 hospitalizations involving esophageal stricture; 4.2% were malignant. Endoscopic dilation was performed in 28.7% cases. Dilation was more frequently utilized (odds ratio [OR], 1.36; p<0.001), had higher in-hospital mortality (3.1% vs. 1.4%, p<0.001), and resulted in longer hospital stays (5 days vs. 4 days, p=0.01), among cases of malignant strictures. Esophageal perforation was more common in the malignant group (0.9% vs. 0.5%, p=0.007). Patients with malignant compared to benign strictures undergoing dilation were more likely to require percutaneous endoscopic gastrostomy or jejunostomy (PEG/J) tube (14.1% vs. 4.5%, p<0.001). Palliative care services were utilized more frequently in malignant stricture cases not treated with dilation compared to those that were dilated. Conclusions Inpatient endoscopic dilation was utilized in 29% cases of esophageal stricture. Esophageal perforation, although infrequent, is more common in malignant strictures. PMID:28301921

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study. PMID:26011220

Extensive anastomotic leaks after esophageal resection and esophageal perforations are a therapeutic challenge. The aim of the present study was to assess the potential of the self-expandable Polyflex plastic stent for the treatment of these conditions. Between January 2002 and March 2003, nine patients were treated with a self-expandable Polyflex plastic stent for sealing of thoracic esophagoenteric anastomotic leaks following surgical resection (n = 5) or esophageal perforation (n = 4). In all patients the stents were inserted successfully without technical problems. In all but two patients complete sealing of the leak was achieved as demonstrated by radiography with water-soluble contrast media. The stent migration rate was 30 % and repositioning of the migrated stents was possible in all cases. Complete mucosal healing of the esophageal leaks and stent extraction was achieved in six patients. The stents were in situ for an average period of 135 +/- 78 days. Two critically ill patients with anastomotic leaks died in spite of stent insertion due to sepsis and one patient with esophageal perforation died due to the underlying malignant disease. Our preliminary experience with the self-expanding and removable Polyflex plastic stent for the sealing of anastomotic leaks and esophageal perforations suggests that this stent is a feasible treatment option, in particular, for more extensive esophageal defects, patients with co-morbid conditions, and critically ill patients.

Traumatic digit defects of high complexity and with inadequate local tissue represent challenging surgical problems. Recently, perforator flaps have been proposed for reconstructing large defects of the hand because of their thinness and pliability and minimal donor site morbidity. Here, we illustrate the use of thin latissimus dorsi perforator flaps for resurfacing multiple defects of distal digits. We describe the cases of seven patients with large defects, including digits, circumferential defects and multiple-digit defects, who underwent reconstruction with thin latissimus dorsi perforator flaps between January 2008 and March 2012. Single-digit resurfacing procedures were excluded. The mean age was 56.3 years and the mean flap size was 160.4 cm(2). All the flaps survived completely. Two patients had minor complications including partial flap loss and scar contracture. The mean follow-up period was 11.7 months. The ideal flap for digit resurfacing should be thin and amenable to moulding, have a long pedicle for microanastomosis and have minimal donor site morbidity. Thin flaps can be harvested by excluding the deep adipose layer, and their high pliability enables resurfacing without multiple debulking procedures. The latissimus dorsi perforator flap may be the best flap for reconstructing complex defects of the digits, such as large, multiple-digit or circumferential defects, which require complete wrapping of volar and dorsal surfaces.

Rare complication after thyroidectomy-cervical esophageal stenosis: a case report and literature review.

PubMed

Peng, Hanwei; Wang, Steven J; Li, Weixiong

2014-10-11

The most common complications after thyroidectomy are injuries associated with the recurrent laryngeal nerve and parathyroid gland. Cervical esophagus perforation is an exceptionally rare complication after thyroidectomy; it can usually be resolved by conservative care. Cervical esophageal stenosis secondary to intraoperative esophageal injury during thyroidectomy is much rarer and has not been reported in the literature to date. We report a case of esophageal stenosis following thyroidectomy performed at a peripheral hospital. The patient initially underwent a thyroidectomy for papillary thyroid carcinoma involving the cervical esophagus; esophageal perforation was noted intraoperatively, and closed using three number 4 silk sutures. Cervical esophageal stenosis subsequently developed after conservative care. The patient was successfully treated with cervical esophagectomy and reconstruction using a tubed forearm free flap after a failed attempt at endoscopic recanalization. This case is discussed in conjunction with a review of the literature.

Twenty cases of ischemic colitis are reviewed; 19 were obtained from autopsy files and the diagnosis in one was made from a surgical specimen. The majority of the patients were elderly with generalized arteriosclerosis. In approximately two-thirds of the patients the ischemic colitis was precipitated by preceding trauma, operation or congestive heart failure. Clinically, ischemic colitis is characterized by abdominal pain, distension and bleeding per rectum. Perforation of large bowel may occur. The lesions tend to be localized around the splenic flexure and junction of the descending and sigmoid colon, and in cases following aortic graft surgery the rectum is involved. Microscopically, there is necrosis, hemorrhage and ulceration. In less severe cases the mucosa only is affected. Cases with perforation show necrosis of all layers. It is considered that ischemic colitis is comparatively frequent and should be distinguished from other inflammatory conditions of the colon.

An apparatus is described for taking a multiple of samples of groundwater or pressure measurements from a well simultaneously. The apparatus comprises a series of chambers arranged in an axial array, each of which is dimensioned to fit into a perforated well casing and leave a small gap between the well casing and the exterior of the chamber. Seals at each end of the container define the limits to the axial portion of the well to be sampled. A submersible pump in each chamber pumps the groundwater that passes through the well casing perforations into the gap from the gap to the surface for analysis. The power lines and hoses for the chambers farther down the array pass through each chamber above them in the array. The seals are solid, water-proof, non-reactive, resilient disks supported to engage the inside surface of the well casing. Because of the modular design, the apparatus provides flexibility for use in a variety of well configurations. 3 figures.

Acute perforated peptic ulcer is a leading cause of generalized peritonitis and its management has continued to be a challenging task in our environment. There is a paucity of published reports on acute perforated peptic ulcers in our environment. This study was conducted to evaluate the different pattern of risk factors clinical presentations, management and clinical outcome of patients with acute perforated peptic ulcer in our setting and to highlight the factors that continue to account for the high mortality and morbidity as seen here. A retrospective study where data of seventy-six (76) patients managed for generalized peritonitis due to acute peptic ulcer perforation over a five year period (January 2006-December 2010) were retrieved from medical records of Enugu State University of Science and Technology Hospital (ESUTH). The patients' biodata, clinical and operative findings and treatment outcome were extracted and analysed, after institutional ethical approval was secured. All other cases of generalized peritonitis not traceable to acute peptic ulcer perforation were excluded from the study. There were76 patients; 58 males and 18 females (M:F = 3.2:1) Their ages ranged from 20 to 80years with a mean of 39.5yr and SD ± 13.10years. Majority of the patients 49(64.4%) were 40years of age and below and only 24 (31.6%) had a previous history suggestive of chronic peptic ulcer disease. Twenty five (32.9%) patients presented within 24 h of onset of symptoms of perforation with a mortality of 8.0%. Slightly more than half of our patients 39(51.3%) presented between 24 and 48 h with mortality of 17.9%. Twelve patients (15.8%) presented between 48 and 72 h and the mortality in this group was 58.3%. The latter two groups accounted for most of the mortality in our series. All perforations were anterior perforations within the first 2.5 cm of the duodenum and all had simple closure with pedicled omental patch and peritoneal toilet with copious volumes of warm normal saline. Postoperatively all received Helicobacter pylori eradication therapy and proton pump inhibitors for at least two months. Patient groups who presented early had low mortality rates, but patient groups who presented late had higher mortality rates. Overall mortality was 21%. Copyright © 2013. Published by Elsevier Ltd.

Repair of Tympanic Membrane Perforations with Customized Bioprinted Ear Grafts Using Chinchilla Models.

The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3-5% of cases after ear tube placement, as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year, and the commonly used cartilage grafting technique has a success rate between 43% and 100%. This wide variability in successful tympanoplasty indicates that the current approach relies heavily on the skill of the surgeon to carve the shield graft into the shape of the TMP, which can be extremely difficult because of the perforation's irregular shape. To this end, we hypothesized that patient specific acellular grafts can be bioprinted to repair TMPs. In vitro data demonstrated that our approach resulted in excellent wound healing responses (e.g., cell invasion and proliferations) using our bioprinted gelatin methacrylate constructs. Based on these results, we then bioprinted customized acellular grafts to treat TMP based on endoscopic imaging of the perforation and demonstrated improved TMP healing in a chinchilla study. These ear graft techniques could transform clinical practice by eliminating the need for hand-carved grafts. To our knowledge, this is the first proof of concept of using bioprinting and endoscopic imaging to fabricate customized grafts to treat tissue perforations. This technology could be transferred to other medical pathologies and be used to rapidly scan internal organs such as intestines for microperforations, brain covering (Dura mater) for determination of sites of potential cerebrospinal fluid leaks, and vascular systems to determine arterial wall damage before aneurysm rupture in strokes.

BACKGROUND/ PURPOSE: Perforated peptic ulcer (PPU) is still an existing disease that occurs frequently in the 21st century despite of the wide availability of antiulcer medication and Helicobacter eradication. The current study aimed to evaluate the hypothesis that its outcome might be improved by using the laparoscopy. The outcome of treatment in terms of complications, mortality and hospital stay with relevant to laparoscopy was analyzed. This prospective descriptive study was carried on the period of 3 years from July 2009 till July 2012. All patients with acute abdominal pain that was clinically diagnosed as having perforated peptic ulcer were included. Excluded from this study were those patients with concomitant bleeding from the ulcer and evidence of gastric outlet obstructions. Also excluded were those with evidence of large perforation more than 10 mm and patients with symptoms of more than 36 h durations for fear of septic shock. Forty seven patients were studied out of a total 53 PPU patients; they were 41 males and 6 females with the male to female ratio of 6.8:1. Their age ranged from 19 to 55 years with the mean age of 39.5 ± 8.6 years. Forty five patients were successfully treated by laparoscopy while only 2 cases that were early presented with signs of hypovolumic shock were converted into laparotomy due to severe bleeding. The mean hospital stay was 75 ± 12.6 h. Post operative complications included death of one patient in the postoperative period at the Intensive care unit (ICU) plus post operative fever in the 2 patients who underwent laparotomy and it was amenable to treatment. Laparoscopic repair of a perforated peptic ulcer is an amenable and feasible technique within the hands of experienced laparoscopic surgeon when the cases are early and properly diagnosed.

Advancements in medical care for peptic ulcer disease (PUD) have reduced the need for invasive surgical procedures such as gastric resection (GR). Community-based PUD studies from a large sampling of PUD patients designed to analyze hospital resource use and outcomes after different surgical procedures have been rare. We aimed to exhaustively reappraise the risk factors and patient demographics that affect PUD patient recoveries after GR compared to those after simple closure (SC). We used a Japanese administrative database for 6 consecutive months each year between 2006 and 2010. The database included a total of 68,432 PUD patients; we analyzed 6,334 perforation cases and 3,148 cases of patients who underwent GR or SC. Study variables were demographics, comorbidities, characteristics of PUD, and operative day. Study outcomes that were analyzed included mortality, postoperative complications, ventilation administration, postoperative blood transfusions, length of stay, total charges, operating room (OR) time, and the postoperative fasting period (defined as the day of surgery to the day oral food intake was resumed.) To reduce selection bias in study procedures and to control the variation in hospital practice, a propensity score (PS) matching cohort analysis and a mixed linear regression model were used to assess the effects of GR on the outcomes. In 699 hospitals, 322 GRs and 2,826 SCs were observed. Younger age, duodenal ulcers, preexisting anemia and an operative day no more than 24hours were significant associated with the choice of SCs. No significant differences were observed in study outcomes after either GR or SC; more postoperative blood transfusions and longer OR times but shorter postoperative fasting periods were observed after GR. Longer OR times, ventilation and postoperative blood transfusion were significantly associated with mortality. Not GR but longer OR times use of ventilation and complications were the most significant indicators of increased resource use. There were no major significant differences in GR when compared to SC with regards to patient recoveries. Surgeons should obtain the skills and establish strategies to optimize either type of surgical procedure including minimizing OR time and establishing the best perioperative critical care.

Perforations of the peptic ulcers (PPUs) are the most common cause of emergency surgery among the complications of the gastroduodenal ulcers and the leading cause for morbidity and mortality due to secondary peritonitis and sepsis. PPU is a condition in which laparoscopic perforation repair (LPR) is an optimal solution. It makes possible the identification of the perforation's site and allows closure of the perforation and the subsequent peritoneal lavage, as in an open repair (OR) but without the large upper mid-abdominal incision. The main objective of this review was to evaluate the latest reported results in the laparoscopic treatment of the PPU. Using PubMed and EMBASE databases between 1989 and June 2017 we did an extensive electronic literature search. The search terms used were "laparoscopic perforated peptic ulcer." Inclusion criteria were all the published studies that reported the outcomes of LPR and LPR compared with OR for PPU were included in the analysis. The exclusion criteria included animal or laboratory studies, pediatric surgery trials, papers reporting less than 30 cases of LPR, clinical trials without major outcomes, and other language then English. There were 32 studies included, counting 3488 patients with LPR and 5208 with OR. OR patients had more frequent shock at admission and had a higher ASA risk class. LPR patients had shorter hospital stays with two days, morbidity (11.12% vs. 14.71% OR) and mortality (1.95% vs. 8.35% OR) were lower. Leakage was three times higher in LPR arm (2.18% vs. 0.79% OR). Conversion occurred in 4.18% overall. The three primary reasons for conversions were the size of the perforation, the inability to locate the perforation and technical difficulties. LPR showed similar or better results than OR in terms of morbidity, mortality, operation time and hospital stay, caution is needed as the OR patients tend to be more shocked or with higher ASA at presentation. The higher leakage rate after LPR should be addressed in the training of the laparoscopic surgeons or other safety measures should be developed and employed.

Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

Pneumatosis cystoides intestinalis is a rare disease characterized by presence of multilocular cysts in the gastrointestinal wall. Rarely, patients may experience symptoms secondary to the cysts. The pathogenesis of pneumatosis cystoides intestinalis is still unclear and many theories have been advocated to explain the exact origin. Complications occur in about 3% of cases and include obstruction, intussusception, volvulus, haemorrhage and intestinal perforation. The author reported a male patient aged 56 years presented to the emergency department with acute upper abdominal pain. Widespread variable sized serosal intestinal air cysts were seen at the first look involving long segment of jejunum and ileum. Perforated duodenal ulcer, as the cause of generalized peritonitis, was repaired with direct closure and omental patch. A second laparotomy, was done and exploration was systematically performed and denoted hugely distended stomach with cicatrisation at the site of previous closure of perforated duodenal ulcer and the whole length of small gut was completely free from the already described pneumatosis cystoides intestinalis. The pneumatosis cystoides intestinalis is a rare disease and suspicion of this disease process should be based on imaging and clinical finding. The therapy can be conservative or surgical in restricted situations.

The gastrocnemius muscle flap may be considered the first choice in many cases of soft-tissue reconstruction about the knee. Limited arc of rotation and reach of the flap as well as unsightly muscle bulk are major disadvantages and were the impetus to look for a local alternative. The aim of this study is to present a consecutive series of patients with a reconstruction about the knee involving the medial sural artery perforator flap (MSAPF). A consecutive series of 17 cases of defect reconstructions about the knee using the MSAPF is described, with an emphasis on early postoperative complications. No major flap-related complications occurred except 1 case of tip necrosis that healed uneventfully after excision and secondary suture. Two patients with direct donor-site closure had a minor complication that required no revision, and 2 had partial skin-graft loss. In summary, use of this pedicled perforator flap represents a reliable technique for soft-tissue reconstruction about the knee with an acceptable complication rate and optimal contour reconstruction without the need for a skin graft and secondary debulking procedures. The range of motion associated with the MSAPF in comparison to the range associated with the gastrocnemius muscle flap is increased so that more proximal and lateral defects can be covered.
