RESUMO
BACKGROUND: Anastomotic leakage (AL) after gastrectomy in gastric cancer patients is associated with high mortality rates. Various endoscopic procedures are available to manage this postoperative complication. The aim of study was to evaluate the outcome of two endoscopic modalities, clippings and stents, for the treatment of AL. PATIENTS AND METHODS: There were 4916 gastric cancer patients who underwent gastrectomy between December 2007 and January 2016 at the National Cancer Center, Korea. A total of 115 patients (2.3%) developed AL. Of these, 85 patients (1.7%) received endoscopic therapy for AL and were included in this retrospective study. The endpoints were the complete leakage closure rates and risk factors associated with failure of endoscopic therapy. RESULTS: Of the 85 patients, 62 received endoscopic clippings (with or without detachable snares), and 23 received a stent insertion. Overall, the complete leakage closure rate was 80%, and no significant difference was found between the clipping and stent groups (79.0% vs. 82.6%, respectively; P = 0.89). The complete leakage closure rate was significantly lower in the duodenal and jejunal stump sites (60%) than esophageal sites (86.1%) and gastric sites (94.1%; P = 0.026). The multivariate analysis showed that stump leakage sites (adjusted odds ratio [aOR], 4.51; P = 0.031) and the presence of intra-abdominal abscess (aOR, 4.92; P = -0.025) were associated with unsuccessful leakage closures. CONCLUSIONS: Endoscopic therapy using clippings or stents is an effective method for the postoperative management of AL in gastric cancer patients. This therapy can be considered a primary treatment option due to its demonstrated efficacy, safety, and minimally invasive nature.

Traumatic superior mesenteric artery (SMA) and vein (SMV) injuries are rare but often lethal. The ideal management options of traumatic SMV injury are still controversial. Management options include venous repair and ligation. Splenic vein turndown procedure (SVTP) is a rare procedure that has been described in only 6 cases in the literature. Here, we reviewed the literature on the usage of the splenic vein turndown procedure (SVTP) as an alternative option in patients with traumatic SMV injury. METHODS: We performed a narrative review for the available literature on the usage of the splenic vein as an autologous graft in the management of the SMV injury. We included all studies of SVTP in traumatic SMV injuries only. RESULTS: We included only 5 studies. In total, 7 patients underwent SVTP. Five patients presented with a penetrating abdominal vascular trauma (AVT) and 2 patients with a blunt AVT. The advantages of the SVTP include no need for additional incisions to harvest potential autologous grafts, minimally increased operative time, and 1 less anastomotic site compared to other conduit options. CONCLUSIONS: In cases of traumatic SMV injuries with associated splenic or pancreatic injuries that need distal pancreatosplenectomy, surgeons may consider SVTP as an ideal management option rather than primary repair or ligation.

BACKGROUND: Liver diseases epidemiology has changed with advances in perioperative care. Transplantation at large centers is favorable among older and younger recipients. Local limitations on transplantation for recipients older than 65 years were cancelled in 2014. This study evaluates the effects of age on the transplantation outcome of Israeli patients in the era after removal of the limitations on recipient age. METHODS: This retrospective analysis examined prospective data on patients older than 18 years who underwent liver or liver-kidney transplantation between 2014 and 2019 at 2 transplantation centers. Patients were divided into 4 age groups (group 1: ≤59 years; group 2: 60-64 years; group 3: 65-69 years; and group 4: ≥70 years). Each group's associations of pretransplantation factors with outcome and survival were examined. RESULTS: Two hundred sixty-one recipients underwent 269 transplantations (mean age: 53 ± 12.61 y). There were 181 male (67.8%) and 88 female recipients (67.28%). Overall, 207 patients (79.6%) survived ≥12 months. One-year survival rates were 82.9%, 73.2%, 71.4%, and 93.8% for groups 1 to 4, respectively (not statistically significant; P = .11). One-year graft survival was similar between groups. More patients with chronic obstructive pulmonary disease, diabetes mellitus, or ischemic heart disease tended to survive <12 months. Cardiovascular complication was more common in older groups and affected survival. CONCLUSION: Patient age alone should not be used to deny access to transplantation, which could benefit older nonfrail individuals. However, risk factors such as male sex, chronic obstructive pulmonary disease, ischemic heart disease, diabetes mellitus, and concomitant kidney-liver transplantation should be carefully considered.

BACKGROUND: Selective diagnostic laparoscopy in gastric cancer patients at high risk of peritoneal metastasis is essential for optimal treatment planning. In this study available clinicopathologic factors predictive of peritoneal seeding in advanced gastric cancer (AGC) were identified, and this information was translated into a clinically useful tool. METHODS: Totally 2833 patients underwent surgery for AGC between 2003 and 2013. The study identified clinicopathologic factors associated with the risk of peritoneal seeding for constructing nomograms using a multivariate logistic regression model with backward elimination. A nomogram was constructed to generate a numerical value indicating risk. Accuracy was validated using bootstrapping and cross-validation. RESULTS: The proportion of seeding positive was 12.7% in females and 9.6% in males. Of 2833 patients who underwent surgery for AGC, 300 (10.6%) were intraoperatively identified with peritoneal seeding. Multivariate analysis revealed the following factors associated with peritoneal seeding: high American Society of Anesthesiologists score, fibrinogen, Borrmann type 3 or 4 tumors, the involvement of the middle, anterior, and greater curvature, cT3 or cT4cN1 or cN2 or cN3, cM1, and the presence of ascites or peritoneal thickening or plaque or a nodule on the peritoneal wall on computed tomography. The bootstrap analysis revealed a robust concordance between mean and final parameter estimates. The area under the ROC curve for the final model was 0.856 (95% CI, 0.835-0.877), which implies good performance. CONCLUSIONS: This nomogram provides effective risk estimates of peritoneal seeding from gastric cancer and can facilitate individualized decision-making regarding the selective use of diagnostic laparoscopy.

Objectives: Discriminating simple from complicated diverticulitis solely on clinical bases is challenging. The aim of this study was to identify clinical predictive factor for the need for invasive treatment for patients presenting with acute diverticulitis in the emergency room. Material and Methods: The records of all patients, who were discharged from a university hospital between January 2010 and March 2018 with "diverticulitis" diagnosis, were reviewed. Data collected included clinical features, whether this was a first or recurrent episode, WBC, and Hinchey score. Patients were divided into conservative and invasive treatment groups. Groups were compared by age, sex, BMI, fever, WBC and CT findings. Hinchey score groups were also compared by age, sex, BMI, fever, WBC. Results: A total of 809 patients were included. Mean age was 60.6 years, with 10% below 40 years. Most patients were treated conservatively (95.9%) while only 4.1% were treated invasively. WBC at presentation was significantly higher in those who required invasive treatment in comparison with the conservative group (13.72 vs. 11.46K/uL, p= 0.024). A statistically significant higher WBC was found among patients with a higher Hinchey score (13.16 vs 11.69, p <0.005). No difference between the groups was found in terms of age, sex, fever or BMI. Conclusion: This study showed that patients who present with acute diverticulitis and an elevated WBC are prone to a more severe disease and a higher Hinchey score. Prudence should be taken with these patients, and CT scan is warranted as there is a greater chance that invasive treatment will be required.
RESUMO
Backgrounds/Aims: The soft texture of the pancreas parenchyma may influence the incidence of pancreatic leakage after pancreaticoduodenectomy (PD). One possible method to assess pancreatic texture and atrophy, is via computed tomography (CT) scan of the abdomen. The purpose of our study was to evaluate the relation between the preoperative CT scan and the incidence of pancreatic fistula after PD. Methods: A retrospective single-center study including patients who underwent PD for a benign and malignant tumor of the periampullary region between the years 2000 and 2016. Demographic and imaging data were analysed and a correlation with the post-operative leak was evaluated. Results: Pancreatic leak was documented in 34 out of 154 (22.1%) patients. All the leakage cases occurred in the preserved pancreas group (33.1% of the total preserved pancreas group alone). No leak was documented in the atrophic pancreas group. This difference between the two groups was found to be statistically significant (p ≤ 0.00001). Conclusions: Atrophic pancreas in the preoperative CT scan may be protective against leakage after PD. These findings may help the surgeon to risk stratify patients accordingly. In addition, the findings suggest that patients with a preserved pancreas may require more protective methods to prevent leakage.
RESUMO
We introduced SPADE operation, a novel anastomotic method after laparoscopic proximal gastrectomy (PG). Technical modifications were performed and settled. This report aimed to demonstrate the short-term clinical outcomes after settlement. Data from 34 consecutive patients who underwent laparoscopic PG with SPADE between June 2017 and March 2020 were retrospectively reviewed. Reflux was evaluated based on the patients' symptoms and follow-up endoscopy using Los Angeles (LA) classification and RGB Classification (Residue, Gastritis, Bile). Other complications were classified using the Clavien-Dindo method. The incidence of reflux esophagitis was 2.9% (1/34). Bile reflux was observed in six patients (17.6%), and residual food was observed in 16 patients (47.1%) in the endoscopy. Twenty-eight patients had no reflux symptoms (82.4%), while five patients (14.7%) and one patient (2.9%) had mild and moderate reflux symptoms, respectively. The rates of anastomotic stricture and ileus were 14.7% (5/34) and 11.8% (4/34), respectively. No anastomotic leakage was observed. The incidence of major complications (Clavien-Dindo grade III or higher) was 14.7%. The SPADE operation following laparoscopic PG is effective in reducing gastroesophageal reflux. Its clinical usefulness should be validated using prospective clinical trials.
RESUMO
Backgrounds/Aims: Traumatic pancreatic injury (TPI) is rare as an isolated injury. There is a trend to perform conservative treatment even in patients with complete duct dissection and successful treatment. This study reviewed our 20 years of experience in the management of TPI and assessed patient outcomes according to age group and treatment strategy. Methods: A retrospective analysis of patients diagnosed and treated with TPI at a level-I trauma center from 2000-2019. Patients were divided into two groups: adults and pediatrics. Conservative treatment cases were subjected to subgroup analysis. Level of evidence: IV. Results: Of a total of 77 patients, the mean age was 24.89 ± 15.88 years. Fifty-six (72.7%) patients had blunt trauma with motor vehicle accident. Blunt trauma was the predominant mechanism in 42 (54.5%) patients. Overall, 38 (49.4%) cases had grade I or II injury, 24 (31.2%) had grade III injury, and 15 (19.5%) had grade IV injury. A total of 30 cases had non-operative management (NOM). Successful NOM was observed in 16 (20.8%) cases, including eight (32.0%) pediatric cases and eight (15.4%) adult cases. Higher American association for the surgery of trauma (AAST) grade of injury was associated with NOM failure (16.7% for grade I/II, 100% for grade III, and 66.7% for grade IV injury; p = 0.001). An independent factor for NOM failure was female sex (69.2% in females vs. 29.4% in males; p = 0.03). Conclusions: High AAST grade TPI is associated with a high rate of NOM failure in both pediatric and adults.
RESUMO
Oesophageal schwannomas are extremely rare tumours arising from Schwann cells of the neural sheath, with less than 115 cases reported in the English literature. These tumours are usually sporadic and account for about 2% of all stromal oesophageal tumours. Diagnosis is usually confirmed by the presence of positive immunohistochemical marker S-100 and absence of CD117, CD34, smooth muscle actine and Desmin. Treatment can vary from enucleation to oesophagectomy. Herein, we report a case of a 61-year-old woman who presented with progressive dysphagia. Computerized tomography scan revealed a 5 × 3 cm mass extending proximal to the azygos arch. Oesophagogastroduodenoscopy showed a submucosal mass at 20-24 cm from the incisors. Endoscopic ultrasound showed a 6 × 3 cm well-circumscribed mass originating from the fourth layer, suspicious for a gastrointestinal stromal tumour. The patient underwent thoracoscopic enucleation of the tumour in a semi-prone position. Final pathology was consistent with a completely resected benign oesophageal schwannoma, positive for S-100.

Importance: Segmental gastrectomy, a type of function-preserving surgery, is not broadly studied but can improve postoperative function and quality of life among patients with gastric cancer (GC). Objective: To establish an indication for middle segmental gastrectomy (MSG) as a treatment for middle-body (MB) and high-body (HB) GC. Design, Setting, and Participants: This cohort study analyzed patients with GC undergoing surgery between January 2000 and December 2015 in the National Cancer Center, Goyang, Korea, a high-volume cancer center with a structured database and accurate long-term follow-up. Inclusion criteria were age 18 to 85 year, histologically proven adenocarcinoma located in the HB or MB, cT1 to cT3 category cancers, curative resection with negative margins performed, and follow-up for at least 3 years. Exclusion criteria were Borrmann type 4 GC, T4 category cancer, neoadjuvant chemotherapy, and a history of other cancers. Data analysis was performed from December 2018 to May 2020. Exposures: Total or subtotal gastrectomy and LN dissection. Main Outcome and Measures: The primary outcome was the rate of metastasis at LN stations 2, 4sa, 5, 6, and 11d, which cannot be dissected during MSG. Results: Among 9952 patients who underwent surgery for GC, 8219 underwent either laparoscopic or open total or subtotal gastrectomy. Seven hundred seventy-three patients (mean [SD] age, 56.21 [12.16] years; 464 men [60.0%]) had GC in the MB or HB of the stomach. Among the 701 patients included in the final analysis after exclusion of the cN2/N3 carcinomas, the mean (SD) age was 56.35 (12.24) years, and 418 (59.6%) were men. The incidence of LN metastasis was 0% at station 5 for cT1-3N0/1M0 cancers, station 4sa for cT1-2N0/1M0 cancers, station 2 for cT1N0/1M0 cancers, station 6 for cT1N1M0 cancers, station 11d for cT1N1M0-cT2N0/1M0 cancers, and station 12a for cT1N0/1M0-T2N1M0 cancers, regardless of size and differentiation. The rates of LN metastasis for cT1N0M0 cancers were 0.3% (1 of 396 LNs) at station 6 and 0.8% (1 of 129 LNs) at station 11d. Tumors 4 cm or smaller were associated with a lower risk of LN metastasis compared with tumors 4.1 cm or larger (odds ratio, 2.10; 95% CI, 1.20-3.67; P = .009), and well-differentiated tumors were associated with lower risk of LN metastasis compared with poorly differentiated tumors (odds ratio, 2.88; 95% CI, 1.45-5.73; P = .002). Conclusions and Relevance: These findings suggest that MSG with dissection of stations 1, 3, 4sb, 4d, 7, 8a, 9, 11p, and 12a could be done for HB and MB cT1N0/1M0 gastric cancers 4 cm or smaller and well-differentiated cT2N0/1M0 cancers.

Importance: It is unclear whether proximal gastrectomy (PG) can replace total gastrectomy (TG), even in cases of advanced gastric carcinoma. Objectives: To evaluate the oncologic safety of PG based on the lymph node (LN) metastasis rate and develop a selection diagram for PG eligibility. Design, Setting, and Participants: In this cohort study, a retrospective analysis of a prospective database of gastric carcinoma surgery was performed including procedures that took place between December 1, 2000, and December 31, 2015, in the National Cancer Center, Korea, a high-volume carcinoma center with a structured database and accurate long-term follow-up. Among 9952 patients who underwent surgery for gastric carcinoma, 2347 underwent TG. Six-hundred fifty-five (564 in a second statistical analysis) had gastric carcinoma in the upper third of the stomach. The inclusion criteria were age 18 to 85 years, histologically proven adenocarcinoma (any size or differentiation) located in the upper third of the stomach, curative R0 TG performed, and postoperative follow-up for at least 3 years. Exclusion criteria included Borrmann type 4 carcinoma, T4 category, use of neoadjuvant chemotherapy, and a history of other carcinomas. Data analysis was performed from December 1, 2019, to May 30, 2020. Exposures: Total gastrectomy and LN dissection. Main Outcomes and Measures: The primary end point was the rate of LN metastasis at LN stations 4d, 5, and 6, which are usually not dissected during PG. Results: Among the 655 study patients, the mean (SD) age was 57.7 (11.9) years, and 462 (70.5%) were men. Only those with poorly differentiated cT3 category carcinomas had an increased incidence of LN metastasis at stations 4d (2 of 32 [6.3%]) and 11d (T3N0: 2 of 22 [9.1%], T3N1: 3 of 27 [11.1%]), independent of tumor size. For cT1-T3N0/1M0 category carcinomas, the incidence of station 5 LN metastasis was 0, irrespective of tumor size and differentiation. The LN metastasis rate at stations 4d and 6 for cT1-T3N0/1M0 differentiated tumors was also 0. Tumor size greater than or equal to 4.1 cm was associated with significantly increased LN metastasis compared with tumors less than 4.1 cm (40.0% vs 20.4%, P = .001). Conclusions and Relevance: The findings of this study suggest that PG can be safely performed for cT1-T2N0/1M0 tumors less than 4.1 cm in diameter that are located in the upper third of the stomach. The cT3N0/1M0-differentiated tumors less than 4.1 cm may also be eligible for PG, whereas poorly differentiated cT3 tumors and any cT4 or cN2/3 diseases require TG.

OBJECTIVE: Feasibility of diagnosis of pneumothorax using handheld ultrasound by non-radiologists shows inconsistent results. The aim of this study is to evaluate the feasibility and accuracy of portable ultrasound for immediate diagnosis of pneumothorax by general surgery residents who underwent short training. METHODS: Patients who presented to the emergency department of a university hospital with suspected pneumothorax between 10/2018 and 12/2019 were included in the study. Patients underwent ultrasound in 2 points of each hemithorax. Sensitivity and specificity for pneumothorax diagnosis by ultrasound and physical examination were calculated and compared with chest computed tomography (CT). Patients in whom a chest tube was placed prior to ultrasound examination and those who did not undergo a CT scan were excluded from the study. RESULTS: A total of 85 patients met the inclusion criteria. Mean age was 40.7 ± 20.2 years. Pneumothorax was found among 46 patients (54%) per chest CT, and of these, 21 (46%) underwent chest tube placement following imaging. Ultrasound showed the highest sensitivity and specificity (95.6% [95% confidence interval {CI} 85.16% to 99.47%] and 97.44% [95% CI 86.40% to 99.67%], respectively). Chest x-ray had the lowest sensitivity (47.8% [95% CI 32.89% to 63.05%]) for pneumothorax detection. Physical examination showed a moderate sensitivity and specificity (82.6% [95% CI 68.58% to 92.18%] and 77.89% [95% CI 60.67% to 88.87%], respectively) for the diagnosis of pneumothorax. CONCLUSIONS: We found high accuracy rates of 2-point ultrasound in immediate pneumothorax diagnosis when performed by surgical residents who underwent a short ultrasound training. This is a fast and repeatable test, and has the potential for successful implementation in prehospital and military scenarios as well, minimizing unnecessary chest tube placements.

PURPOSE: The necessity of routine preoperative esophagogastroduodenoscopy (EGD) and upper gastrointestinal series (UGIS) in the evaluation of hiatal hernia (HH) among bariatric surgery candidates is controversial since most are detected during surgery, regardless of the preoperative work-up. The aim is to determine the accuracy of preoperative EGD and UGIS for HH diagnosis among bariatric surgery candidates. MATERIAL AND METHODS: The records of bariatric surgery patients between 2011 and 2015 were reviewed. Patients underwent routine UGIS and/or EGD before the surgery. The positive and negative predictive values (PPV, NPV) for each study were calculated based on operative findings. RESULTS: A total of 463 patients were included in the study. Mean age was 44.34 ± 12.99 years. Mean preoperative body mass index (BMI) was 42.7 ± 5.15 kg/m2. A total of 450 patients (97.2%) had a UGIS, 263 patients underwent EGD (56.8%), and 258 (55.7%) patients had both tests. HH was diagnosed in 26 (5.8%), 60 (13%), and 72 (27.8%) patients, respectively. HH was found intra-operatively in 53 patients (11.4%). It was associated with heartburn (P = 0.005) and previous bariatric surgery (P = 0.008). EGD had a greater sensitivity than UGIS (47.4% vs. 30.2%) and a lower specificity (81.4% vs. 97.5%). PPV and NPV for UGIS and EGD were 61.5% and 91.3% vs. 30% and 90.2%, respectively. The sensitivity of both tests when combined together reached 60.5%. CONCLUSIONS: Both EGD and UGIS, whether solely performed or combined, have low sensitivity for diagnosis of HH and can probably be omitted from the preoperative evaluation, except for high-risk patients.

PURPOSE: This study aimed to evaluate the outcomes of the Bascom cleft lift (flap) and the pilonidal pits excision (Gips procedure). METHODS: The records of all the patients who underwent pilonidal sinus excision between November 2013 and August 2017 were reviewed. Inclusion criteria included either pilonidal pits excision or the Bascom cleft lift procedure. All procedures were performed by a single surgeon. Perioperative complications and recurrence rates were reviewed. RESULTS: Fifty-three patients met the inclusion criteria. Male/female ratio was 36/17, with a mean age of 23.4 ± 7 years. In this study, 21 patients underwent the Bascom cleft lift (skin flap) procedure and 32 underwent the Gips-style operation. The mean follow-up was 3.5 months. Twenty-eight patients (52.8%) underwent prior drainage of pilonidal abscess. Eleven patients had a previous wide local excision with recurrent disease. A higher rate of recurrence was observed among patients who underwent pits picking following failure of a previous wide local excision (80% vs. 0%, P = 0.02). Minor wound dehiscence developed in 8 patients; all of which were in the Bascom flap group (40% vs. 0%, P < 0.005). All of these wounds healed completely between 3 and 6 weeks. CONCLUSION: The Gips procedure is the recommended treatment for simple pilonidal disease. For recurrent pilonidal disease, the Bascom cleft lift (flap) procedure is an excellent option since it demonstrates a short wound healing time and a good success rate. This calls into question the continued use of the wide excision technique used by most surgeons in this country and abroad.
RESUMO
BACKGROUND: Tumor size is an important parameter in breast cancer staging. Definitive tumor size is determined by measurement of the pathologic specimen. However, prior to surgery, size must be assessed by imaging with mammography (MMG), ultrasound (US), or magnetic resonance imaging (MRI). Discrepancies between imaging-assessed and pathologic size are not uncommon. Breast density decreases the sensitivity of MMG, and may affect image-based tumor size assessment. AIM: To compare tumor size assessed by the different imaging modalities to pathologic size across breast densities. MATERIAL & METHODS: This was a retrospective analysis of 183 female patients (197 breast cancers) diagnosed and operated for primary breast cancer at a single center. Tumor size measurements were collated for each available imaging modality and compared with measurements from pathologic specimens. Breast density was assessed on MMG using the Breast Imaging Reporting and Data System. RESULTS: Mean pathologic tumor size was 23.0 ± 19.3 mm. Mean tumor size did not differ significantly with MMG (22.3 ± 16.6 mm; P = 0.165) or MRI (23.4 ± 19.2 mm; P = 0.620). However, US significantly underestimated mean tumor size (15.2 ± 8.6 mm; P = 0.0001 vs pathology). Breast density did not affect the accuracy of tumor size assessment by any imaging modality. CONCLUSIONS: US may underestimate breast tumor size. Treatment decisions that take into account tumor size can be made equally reliably in patients with high or low breast density.

Purpose: Various reconstruction methods have been proposed to reduce reflux after proximal gastrectomy, and we report here a double shouldering technique. The purpose of this study is to compare the novel double shouldering technique with conventional esophagogastrostomy in terms of short term and 3-year clinical outcome. Methods: A retrospective observational case control study was performed on 63 patients for cT1N0 upper third gastric cancer who underwent proximal gastrectomy from January 2012 to November 2016 at the National Cancer Center, Korea. There were 26 patients with conventional esophagogastrostomy, and 37 patients with novel double shouldering technique. The primary outcome was endoscopic reflux esophagitis findings one and three year after surgery according to Los Angeles classification. Secondary outcomes were short term surgical outcome and reflux symptom. Results: There was no significant difference in reflux esophagitis on endoscopic findings at 1 and 3 years after surgery between the two group. The double shouldering (DS) technique group showed significantly better postoperative outcomes with bile reflux at one and three years via endoscopic findings versus conventional esophagogastrostomy (CEG). Operative time and hospital stay were significantly shorter in the CEG group than the DS group. There was no significant difference in terms of reflux symptoms and complications. Conclusion: This novel DS technique is a reconstruction method for use after proximal gastrectomy. It did not show a significant clinical benefit. Development of surgical techniques and further study is needed to identify the optimal reconstruction method after proximal gastrectomy.
RESUMO
Cystic echinococcosis (CE) is a widely endemic helminthic disease caused by infection with the Echinococcus granulosus tapeworm. Following ingestion of eggs, hydatid cysts develop, most frequently in the liver and lungs, but occasionally in other organs. Infection of the pancreas by hydatid cysts is very rare, even in endemic areas. Most cases of pancreatic hydatid cysts reported in the literature were treated surgically using traditional open laparotomy. There are only few case reports describing laparoscopic treatment for this disease. Herein, we report on an eighteen-year-old female patient who was referred to our institution with a hydated pancreatic tail cyst. After a course of treatment with Albendazole, we successfully performed laparoscopic splenic-sparing distal pancreatectomy to remove the cyst with an uneventful intra- and post-operative course.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective procedure in the management of morbid obesity with variations in outcome, which are technique dependent. Anastomotic stricture remains an important complication. The aim of this study was to assess the long-term outcome of patients undergoing either a linear-stapled anastomosis (LSA) or circular-stapled anastomosis (CSA) with an emphasis on postoperative stricture formation and excess body weight loss (EBWL). METHODS: Medical records of all patients who underwent bariatric surgery between 2008 and 2013 at a single bariatric surgical center were reviewed. All patients who had a LRYGB were included in the study. Patients were divided in two groups based on stapling technique-LSA and CSA. Patient groups were compared with regard to perioperative complication, EBWL. RESULTS: A total of 114 patients were included in the study. There were 51 patients in the LSA group and 63 in the CSA group. No differences were found between the two groups with regard to operative time, hospital stay, or in the EBWL over a 12-month follow-up period. Anastomotic stricture developed in 4 patients, all occurring in the LSA group (7.8%). Three of these patients had undergone successful endoscopic dilatation. CONCLUSIONS: Both stapling techniques resulted in a similar EBWL during the follow-up period and an acceptable safety profile. Anastomotic stricture rate was slightly higher in the LSA, but this did not affect EBWL.

BACKGROUND: Neonatal sigmoid volvulus is a rare entity. It is associated with Hirschsprung's disease. Presentation is acute abdominal distention, vomiting and obstipation. Abdominal radiograph will show the "coffee bean" sign, but this is frequently missed and the diagnosis requires a high index of suspicion. Treatment options include contrast enema, colonoscopy or laparotomy, depending on the condition of the baby and local availability. POPULATION AND RESULTS: During the last 6years, 6 infants with sigmoid volvulus were treated in our department. Four presented during the first 48h since birth, and 2 presented at the age of 2 and 7weeks of age. One child was operated and 5 had primary contrast enema with radiologic de-volvulus. Rectal biopsy was performed in all cases; three children had Hirschsprung's disease. Those with normal biopsies responded well to rectal washouts. Two patients had early one stage transanal pullthrough and one had 2 further occasions of sigmoid volvulus prior to definitive surgery. All three recovered with an uneventful course. CONCLUSIONS: Neonatal sigmoid volvulus requires a high level of suspicion. Contrast enema is efficient for primary de-volvulus. Rectal biopsy should be performed and if positive for Hirschsprung's disease, surgery should be performed sooner rather than later.
