Laparoscopic necrosectomy for acute necrotising pancreatitis: Retrospective analysis of a decade-long experience from a tertiary centre.

INTRODUCTION: The objective of this study is to evaluate the role of minimally invasive surgery for the management of necrotising pancreatitis in acute settings and to propose tailor-made approaches to deal with various locations of pancreatic necrosis. PATIENTS AND METHODS: Three hundred and thirteen patients underwent laparoscopic management of necrotising pancreatitis in this study period from January 2010 to June 2021, out of which 122 patients underwent minimally invasive necrosectomy for acute necrotising pancreatitis. The remaining 191 patients underwent laparoscopic internal drainage in the form of cystogastrostomy/cystojejunostomy for walled-off pancreatic necrosis. RESULTS: Mean body mass index was 26.45 ± 3.78 kg/sqm. Mean operating time was 56.40 ± 20.48 min and mean blood loss was 120 ± 31.45 mL. Ten patients required reoperation (6 underwent open procedure and 4 underwent laparoscopic redo necrosectomy). Six patients died of multi-organ failure. The mean duration of return of bowel function was 5 ± 1.8 days. The mean length of hospital stay after surgery was 10.19 ± 7.09 days. There were no major wound-related complications. CONCLUSION: A minimally invasive approach to pancreatic necrosectomy is safe and feasible with good outcomes in centres with advanced laparoscopic expertise. It requires not only careful case selection but also proper timing and the ideal route of access to achieve optimal outcomes.

Are drains useful in eTEP ventral hernia repairs? An AWR surgical collaborative (AWRSC) retrospective study.

BACKGROUND: Drain practices in minimally invasive retromuscular ventral hernia repairs have largely been transferred over from open surgery without significant review. We wished to evaluate the role of drains in these repairs. METHODS: Using the Abdominal Wall Reconstruction Surgical Collaborative (AWRSC) registry, patients with ventral hernias who underwent enhanced-view totally extraperitoneal (eTEP) repairs between February 2016 and September 2019 were evaluated. Patients with contamination or active infection within the surgical field, those who underwent an emergent or hybrid repair, or received a concomitant procedure were excluded. Propensity score matching based on the defect size, previous hernia repair status, and the use of posterior component separation (PCS) was used to match patients with drains to patients without drains. We evaluated 180-day outcomes in terms of SSIs, SSOs, and recurrence. RESULTS: 308 patients met the inclusion criteria. After propensity score matching, 48 patients with drains and 72 without drains were included in the analysis cohort. Those with drains were older with a greater likelihood of an incisional hernia, but were broadly similar for other relevant demographic and hernia-related variables. While there was no difference in the incidence of SSOs and SSIs between the two groups, we report a higher risk of SSOs needing procedural intervention (SSOPI) and recurrence, with a lengthened hospital stay in the cohort that received surgical drains. CONCLUSION: The use of surgical drains in "clean" eTEP repairs of ventral hernias appears to be common, with a selection bias for more complex cases. Based on our analysis, we found the use of drains was associated with longer hospital stays. The use of drains did not change the likelihood of suffering an SSI or SSO. However, the incidence of SSOPIs was higher despite the use of drains, which raises questions about their protective role in these repairs.

Laparoscopic versus open pancreatoduodenectomy: an individual participant data meta-analysis of randomized controlled trials.

BACKGROUND: Randomized trials have compared laparoscopic pancreatoduodenectomy (LPD) to open pancreatoduodenectomy (OPD) with conflicting results. An IPDMA may give more insight into the differences between LPD and OPD, and could identify high-risk subgroups. METHODS: A systematic literature search was performed in the Pubmed, Embase, and the Cochrane library databases (October 2019). Out of 1410 studies, three randomized trials were identified. Primary outcome was major complications (Clavien-Dindo grade ≥ III). Subgroup analyses were performed for high-risk subgroups including patients with BMI of ≥25 kg/m2, pancreatic duct <3 mm, age ≥70 years, and malignancy. RESULTS: Data from 224 patients were collected. After LPD, major complications occurred in 33/114 (29%) patients compared to 34/110 (31%) patients after OPD (adjusted odds ratio (OR) 0.62; 95% confidence interval (CI) 0.3-1.4, P = 0.257). No differences were seen for major complications and 90-day mortality LPD 8 (7%) vs OPD 4 (4%) (adjusted OR 0.2; 95% CI 0.02-1.3, P = 0.080). With LPD, operative time was longer (420 vs 318 min, p < 0.001) and hospital stay was shorter (mean difference -6.97 days). Outcomes remained stable in the high-risk subgroups. CONCLUSION: LPD did not reduce the rate of major postoperative complications as compared to OPD. LPD increased operative time and shortened hospital stay with 7 days.

Extended View: Totally Extra Peritoneal (e-TEP) Approach for Ventral and Incisional Hernia-Early results from a single center.

BACKGROUND: Laparoscopy for ventral hernia repair is now an established technique with its proven benefits of less pain, early recovery, low-recurrence rate as compared to open repair. Several techniques have been described such as IPOM, MILOS, TES, EMILOS, SCOLA, e-TEP. e-TEP was originally conceptualized as an alternative approach to inguinal hernia in difficult cases (obese, previous scars) and for training surgery residents. Application of this approach for ventral hernia repair has recently been reported by few surgeons. We present our experience of e-TEP approach for ventral hernia from a tertiary care center in South India over one year duration. MATERIALS AND METHODS: Electronically maintained data of patients who underwent e-TEP for ventral hernia during a period of November 2017 to November 2018 was reviewed retrospectively. Their demographic data, intraoperative details, postoperative complications and follow up data for a period of 6 months was noted. RESULTS: 171 patients underwent e-TEP approach ventral hernia repair. Mean age was 49.34 ± 10.75 years with hypertension being most common comorbidity. Mean BMI was 29.2 ± 4.1 kg/m2. Mean defect area was 51.35 ± 45.09 cm2 and mean mesh size used was 397.56 ± 208.83 cm2. Fifty patients required TAR. Mean duration of surgery was 176.75 ± 62.42 min and blood loss was 78.7 ± 24.4 ml. Mean length of stay was 2.18 ± 1.27 days. Seven cases had paralytic ileus, 5 cases had surgical site infection, and 3 cases had recurrence at 6 months follow up. CONCLUSION: e-TEP is a minimally invasive approach which is safe, feasible and also avoids placement of mesh in peritoneal cavity. Since it is a relatively new approach it requires further studies for standardization of techniques, criteria for patient selection and to study long-term outcomes.

A comparative prospective study of short-term outcomes of extended view totally extraperitoneal (e-TEP) repair versus laparoscopic intraperitoneal on lay mesh (IPOM) plus repair for ventral hernia.

BACKGROUND: Currently, minimally invasive approach is preferred for the treatment of ventral hernias. After the introduction of extended view totally extraperitoneal (e-TEP) technique, there has been a constant debate over the choice of better approach. In this study, we compare the short-term outcomes of e-TEP and laparoscopic IPOM Plus repair for ventral hernias. METHODS: This is a comparative, prospective single-center study done at GEM Hospital and research center Coimbatore, India from July 2018 to July 2019. All patients who underwent elective ventral hernia surgery with defect size of 2 to 6 cm were included. Patient demographics, hernia characteristics, operative and perioperative findings, and postoperative complications were systematically recorded and analyzed. RESULTS: We evaluated 92 cases (n = 92), 46 in each group. Mean age, sex, BMI, location of hernia, primary and incisional hernia, and comorbidity were comparable in both the groups. Mean defect size for IPOM Plus and e-TEP was 4 cm and 3.89 cm, respectively. Operative time was significantly higher for e-TEP, while postoperative pain (VAS), analgesic requirement, and postoperative hospital stay were significantly less as compared to IPOM Plus. However, 2 cases (4.35%) of e-TEP had recurrence but none in IPOM Plus group. CONCLUSION: e-TEP is an evolving procedure and comparable to IPOM Plus in terms of postoperative pain, analgesic requirement, cost of mesh, and length of hospital stay. More randomized controlled and multicentric studies are required with longer follow-up to validate our findings.

Chronic encysted giant seroma post-ventral hernia repair masquerading as peritoneal cyst and its laparo-seroscopic management: A case report and literature review.

Seroma formation is one the most common occurrence post-ventral hernia repair, with varied presentation from asymptomatic collection to infected collection to chronic collection, which may sometimes present as a diagnostic dilemma and therapeutic challenge. We report a case of giant abdominal swelling presenting as an encysted peritoneal cyst, which was ultimately found to be a chronic seroma and was managed successfully with combined laparo-seroscopic approach.

Laparoscopic approach in cholecystogastric fistula with cholecystectomy and omental patching: A case report and review.

Cholecystoenteric fistulas are rare complications of cholelithiasis, with cholecystogastric fistulas (CGFs) being the rarest. Recommended treatment is surgery; however, select asymptomatic patients can be managed conservatively. The population frequently involved is old age with multiple comorbidities. Open surgery comes with its added morbidities, especially in this subgroup and hence laparoscopic surgery might be beneficial. Sometimes, these fistulas can be incomplete. Here, we describe a case of incomplete CGF managed by laparoscopic cholecystectomy and omental patching along with a brief review of the literature.

Robotic transduodenal excision of duodenal duplication cyst: Case report and review.

Duodenal duplication cysts are rare congenital anomalies that generally present with abdominal pain and vomiting or may have nonspecific symptoms. Surgical excision is the recommended treatment owing to possible complications, including malignancy. However, difficult locations like the periampullary region are problematic and major surgical procedures, for example, pancreaticoduodenectomy is necessary for total resection. These have a high complication rate resulting in a poor quality of life, especially in children and young adults. Here, we describe a case of duodenal duplication cyst managed by robotic (transduodenal) excision along with a brief review of the literature.

The Miami International Evidence-based Guidelines on Minimally Invasive Pancreas Resection.

OBJECTIVE: The aim of this study was to develop and externally validate the first evidence-based guidelines on minimally invasive pancreas resection (MIPR) before and during the International Evidence-based Guidelines on Minimally Invasive Pancreas Resection (IG-MIPR) meeting in Miami (March 2019). SUMMARY BACKGROUND DATA: MIPR has seen rapid development in the past decade. Promising outcomes have been reported by early adopters from high-volume centers. Subsequently, multicenter series as well as randomized controlled trials were reported; however, guidelines for clinical practice were lacking. METHODS: The Scottisch Intercollegiate Guidelines Network (SIGN) methodology was used, incorporating these 4 items: systematic reviews using PubMed, Embase, and Cochrane databases to answer clinical questions, whenever possible in PICO style, the GRADE approach for assessment of the quality of evidence, the Delphi method for establishing consensus on the developed recommendations, and the AGREE-II instrument for the assessment of guideline quality and external validation. The current guidelines are cosponsored by the International Hepato-Pancreato-Biliary Association, the Americas Hepato-Pancreato-Biliary Association, the Asian-Pacific Hepato-Pancreato-Biliary Association, the European-African Hepato-Pancreato-Biliary Association, the European Association for Endoscopic Surgery, Pancreas Club, the Society of American Gastrointestinal and Endoscopic Surgery, the Society for Surgery of the Alimentary Tract, and the Society of Surgical Oncology. RESULTS: After screening 16,069 titles, 694 studies were reviewed, and 291 were included. The final 28 recommendations covered 6 topics; laparoscopic and robotic distal pancreatectomy, central pancreatectomy, pancreatoduodenectomy, as well as patient selection, training, learning curve, and minimal annual center volume required to obtain optimal outcomes and patient safety. CONCLUSION: The IG-MIPR using SIGN methodology give guidance to surgeons, hospital administrators, patients, and medical societies on the use and outcome of MIPR as well as the approach to be taken regarding this challenging type of surgery.

Gastrointestinal stromal tumour of stomach: Feasibility of laparoscopic resection in large lesions and its long-term outcomes.

BACKGROUND: Gastric gastrointestinal stromal tumours (GISTs) are rare neoplasms that require excision for cure. Although the feasibility of laparoscopic resection of smaller gastric GIST has been established, the feasibility and long-term efficacy of these techniques are unclear in larger lesions. This study is done to assess the feasibility of the laparoscopic resection of gastric GISTs and their long-term outcomes. METHODS: Patients who underwent laparoscopic resection of gastric GISTs were identified in a prospectively collected database. Outcome measures included patient demographics, operative findings, morbidity and histopathologic characteristics of the tumour. Patient and tumour characteristics were analysed to identify risk factors for tumour recurrence. RESULTS: There were 42 patients with a mean age of 56.7 years and had a mean tumour size was 4.5 ± 2.7 cm. Laparoscopic wedge resection was the most common procedure done. There were no major perioperative complications or mortalities. All lesions had negative resection margins. At a mean follow-up of 48 months, 36/39 (92.3%) patients were disease free and 3/39 (7.6%) had progressive disease. Univariate analysis showed that there was a statistically significant association of disease progression with tumour size, high mitotic index, tumour ulceration and tumour necrosis. The presence of >10 mitotic figures/50 high-power field was an independent predictor of disease progression. CONCLUSION: Our study establishes laparoscopic resection is feasible and safe in treating gastric GISTs for tumours >5 cm size. The long-term disease-free survival in our study shows acceptable oncological results in comparison to historical open resections.

Laparoscopic Roux-en Y duodenojejunostomy: A safe and physiological treatment for symptomatic annular pancreas in adults.

Background: Annular pancreas is a rare, congenital, rotational anomaly of pancreas, seen usually in newborns who present with features of duodenal obstruction. However, in adults, only 24% of cases are present with duodenal obstruction. Surgery remains the procedure of choice in patients in whom symptoms can be attributed to duodenal obstruction and the goal of surgery is to relieve obstruction by bypassing the annulus. Laparoscopic Roux-en Y duodenostomy (DJ) is our preferred bypass approach for this condition. Literature search revealed that very few case reports have been published about laparoscopic management of annular pancreas, especially about duodenojejunal anastomosis. We present our experience in the laparoscopic management of symptomatic annular pancreas in adults and technique of the laparoscopic Roux-en Y DJ for annular pancreas. Materials and Methods: Between 1996 and 2016, a total of six adult patients underwent laparoscopic management for symptomatic annular pancreas. The demographic, perioperative and follow-up details were documented. Results: All surgeries were successfully performed by laparoscopic approach with no conversion to open. Five cases underwent Roux-en Y DJ and one underwent gastrojejunostomy. No major perioperative events occurred. The mean length of hospital stay was 5.6 days. Five out of six patients were followed up for 24 months, and no symptom recurrence was seen. Conclusion: Laparoscopic Roux-en Y duodenojejunostomy could be used as a safe and physiological treatment for annular pancreas in adult patients and should be preferred for the treatment of duodenal obstruction due to annular pancreas.

Laparoscopic donor hepatectomy: First experience from Indian sub-continent.

Liver transplantation is a ray of hope for thousands of patients with end-stage liver disease but is currently challenged by the scarcity of donor organs worldwide. Unlike kidney transplantation where minimally invasive donor organ procurement has almost become a norm, laparoscopic procurement of hemi-liver from a living donor is still in the infancy of development, at least in the Indian sub-continent. Minimally invasive surgery has made its way into different procedures of hepatobiliary and pancreatic surgery, but only a few centres in the world are performing pure laparoscopic donor hepatectomy. We report two cases of total laparoscopic donor hepatectomy, and to the best of our knowledge, this is the first report from Indian sub-continent.

Robotic-assisted minimally invasive oesophagectomy for cancer: An initial experience.

BACKGROUND: The morbidity related to radical oesophagectomy can be reduced by adopting minimally invasive techniques. Over 250 thoraco-laparoscopic oesophagectomy (TLE) was done in our centre over the last 15 years, before adopting robotic surgery as the latest innovation in the field of minimally invasive surgery. Here, we share our initial experience of robotic-assisted minimally invasive oesophagectomy (RAMIE) for carcinoma oesophagus. METHODS: A prospective observational study conducted from February to December 2017. A total of 15 patients underwent RAMIE in this period. Data regarding demography, clinical characteristics, investigations, operating techniques, and post-operative outcome were collected in detail. RESULTS: There were 10 (66.7%) male patients and the median age of all patients was 62.9 (range 36-78) years. The median body mass index was 24.4 (range 15-32.8) kg/m2. Twelve (80.0%) patients had squamous cell carcinoma (SCC) of the oesophagus and 3 (20%) patients had adenocarcinoma (AC). Five (33.3%) patients received neoadjuvant therapy. All 15 patients underwent RAMIE. Patients with SCC underwent McKeown's procedure, and those with AC underwent Ivor Lewis procedure. Extended two-field lymphadenectomy (including total mediastinal lymphadenectomy) was done for all the patients. The median operating time was 558 (range 390-690) min and median blood loss was 145 (range 90-230) ml. There were no intra-operative adverse events, and none of them required conversion to open or total thoracolaparoscopic procedure. The most common post-operative complications were recurrent laryngeal nerve paresis (3 patients, 20.0%) and pneumonia (2 patients, 13.3%). The median hospital stay was 9 (range 7-33) days. In total, 9 (60%) patients required adjuvant treatment. CONCLUSION: Adequate experience in TLE can help minimally invasive surgeons in easy adoption of RAMIE with satisfactory outcome.

Laparoscopic choledochoduodenostomy as a reliable rescue procedure for complicated bile duct stones.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction is generally accepted as first line management for common bile duct (CBD) stones. CBD exploration, either by open or laparoscopic approach nowadays, is usually reserved for ERCP failures, complicated stone locations, along with altered anatomical situations. The aim of this study was to highlight the increasing role of laparoscopic choledochoduodenostomy which is not only a reliable but also as a rescue procedure for those failed ERCP cases due to complicated bile duct stones. MATERIALS AND METHODS: It is a retrospective review of the database, from a tertiary care teaching institution from India, from Jan 2012 up to December 2016. RESULTS: Out of total 30 patients who underwent laparoscopic choledochoduodenostomy, 28 had failed ERC stone clearance while two patients were directly offered drainage in view of unfavorable anatomy. The major reasons for failed ERC stone clearance were as follows-multiple large calculi (42.8%), recurrent stones (21.4%), and associated stricture (21.4%). Mean operating time was 130 (± 27) minutes with mean blood loss of 60 (± 19) ml. Stone extraction was successful, primarily by milking in 13 (43.33%) patients, rest required augmentation by Dormia basket/balloon. Two patients (6.66%) developed controlled bile leak which resolved with conservative treatment. The median length of hospital stay was 5 days (IQR 3-9). Mean duration of follow-up was 17 (± 3.2) months. CONCLUSION: Laparoscopic common bile duct exploration with choledochoduodenostomy has been shown to be a safe, reliable, and efficient method for treating complex CBDS, especially after failed ERCP procedures.

Single incision multiport versus conventional laparoscopic inguinal hernia repair: A matched comparison.

BACKGROUND: The popularity of single-incision procedures is on the rise as wound cosmesis is increasingly being seen as an important body image-related outcome. In this study, we assess the potential benefits of single-incision multiport laparoscopic totally extra-peritoneal (S-TEP) without using specialised ports or instruments and compare the same with the conventional laparoscopic TEP (C-TEP) surgery in terms of operative time, post-operative pain, complications, cost and cosmesis. MATERIALS AND METHODS: This is a prospective case-matched study of the patients undergoing S-TEP versus C-TEP from June 2014 to December 2015. RESULTS: Each group had 36 patients. The two groups were comparable in the clinical characteristics. The mean duration of surgery for a unilateral hernia in C-TEP and S-TEP was 45.13 ± 10.58 min and 72.63 ± 15.23 min, respectively. The mean visual analogue scale (VAS) score for pain was significantly higher in S-TEP group at post-operative day (POD) 0 and 1. However, at POD 7, there was no significant difference between the groups. At 1st and 6-week post-surgery, the cosmetic results were significantly better in S-TEP group as compared to C-TEP, however, at 6 months, the scar was highly acceptable in both treatment groups. CONCLUSION: S-TEP, using conventional laparoscopic instruments, is safe and feasible even in resource challenged setting. However, there is a need to review the indications and advantages of single-incision laparoscopic surgery, as no difference in cosmetic outcome by VAS score in S-TEP versus conventional laparoscopic arm seen by the end of 1 month.

Laparoscopic management of solid pseudo papillary neoplasm of pancreas in tertiary care center from south India.

BACKGROUND: Solid pseudo papillary neoplasm (SPN) of the pancreas which predominantly affects young women is a relatively indolent entity with favorable prognosis. Resection through minimal access approach helps to achieve better short term benefits. The aim of this study is to describe our experience in laparoscopic management of this disease. METHODS: A retrospective review of our prospectively maintained database revealed that 17 patients with SPN were managed with surgical resection between March 2009 and October 2016. The clinical data of these patients were then analyzed. RESULTS: Among the 17 cases of SPN, 14 were females and 3 were males. The mean age at presentation was 26.1 years (11-46 years). The most common presenting symptom was an abdominal pain (n = 10; 58.8%). A tumor was incidentally detected in 5 patients. The neoplasm was localized in the pancreatic head/neck in 6 patients and in the body/tail in 11. The median diameter of the tumors was 7.5 cm (2-13 cm). Five patients underwent pancreaticoduodenectomy, 10 had distal pancreatectomy, while median pancreatectomy or enucleation was performed in one each. All the patients were offered laparoscopic surgery; one distal pancreatectomy was converted to open in view of bleeding. The median length of stay was 7 days (5-28 days). The patients were followed up for a median period of 31 months (3-62 months). CONCLUSION: SPN is a rare neoplasm with low malignant potential and has an excellent prognosis. In our experience, laparoscopic surgical resection is safe and feasible, even for larger lesions.

Standardizing terminology for minimally invasive pancreatic resection.

BACKGROUND: There is a growing body of literature pertaining to minimally invasive pancreatic resection (MIPR). Heterogeneity in MIPR terminology, leads to confusion and inconsistency. The Organizing Committee of the State of the Art Conference on MIPR collaborated to standardize MIPR terminology. METHODS: After formal literature review for "minimally invasive pancreatic surgery" term, key terminology elements were identified. A questionnaire was created assessing the type of resection, the approach, completion, and conversion. Delphi process was used to identify the level of agreement among the experts. RESULTS: A systematic terminology template was developed based on combining the approach and resection taking into account the completion. For a solitary approach the term should combine "approach + resection" (e.g. "laparoscopic pancreatoduodenectomy); for combined approaches the term must combine "first approach + resection" with "second approach + reconstruction" (e.g. "laparoscopic central pancreatectomy" with "open pancreaticojejunostomy") and where conversion has resulted the recommended term is "first approach" + "converted to" + "second approach" + "resection" (e.g. "robot-assisted" "converted to open" "pancreatoduodenectomy") CONCLUSIONS: The guidelines presented are geared towards standardizing terminology for MIPR, establishing a basis for comparative analyses and registries and allow incorporating future surgical and technological advances in MIPR.

Worldwide survey on opinions and use of minimally invasive pancreatic resection.

BACKGROUND: The introduction of minimally invasive pancreatic resection (MIPR) into surgical practice has been slow. The worldwide utilization of MIPR and attitude towards future perspectives of MIPR remains unknown. METHODS: An anonymous survey on MIPR was sent to the members of six international associations of Hepato-Pancreato-Biliary (HPB) surgery. RESULTS: The survey was completed by 435 surgeons from 50 countries, with each surgeon performing a median of 22 (IQR 12-40) pancreatic resections annually. Minimally invasive distal pancreatectomy (MIDP) was performed by 345 (79%) surgeons and minimally invasive pancreatoduodenectomy (MIPD) by 124 (29%). The median total personal experience was 20 (IQR 10-50) MIDPs and 12 (IQR 4-40) MIPDs. Current superiority for MIDP was claimed by 304 (70%) and for MIPD by 44 (10%) surgeons. The most frequently mentioned reason for not performing MIDP (54/90 (60%)) and MIPD (193/311 (62%)) was lack of specific training. Most surgeons (394/435 (90%)) would consider participating in an international registry on MIPR. DISCUSSION: This worldwide survey showed that most participating HPB surgeons value MIPR as a useful development, especially for MIDP, but the role and implementation of MIPD requires further assessment. Most HPB surgeons would welcome specific training in MIPR and the establishment of an international registry.

Role of routine pre-operative screening venous duplex ultrasound in morbidly obese patients undergoing bariatric surgery.

BACKGROUND/AIMS: It is well established that obesity is a strongly associated risk factor for post-operative deep vein thrombosis (DVT). Physical effects and pro-thrombotic, pro-inflammatory and hypofibrinolytic effects of severe obesity may predispose to idiopathic DVT (pre-operatively) because of which bariatric patients are routinely screened before surgery. The aim of this study was to audit the use of routine screening venous duplex ultrasound in morbidly obese patients before undergoing bariatric surgery. METHODS: We retrospectively reviewed 180 patients who underwent bariatric surgery from August 2013 to August 2014 who had undergone pre-operative screening bilateral lower-extremity venous duplex ultrasound for DVT. Data were collected on patient's demographics, history of venous thromboembolism, prior surgeries and duplex ultrasound details of the status of the deep veins and superficial veins of the lower limbs. RESULTS: No patients had symptoms or signs of DVT pre-operatively. No patient gave history of DVT. No patient was found to have iliac, femoral or popliteal vein thrombosis. Superficial venous disease was found in 17 (8%). One patient had a right lower limb venous ulcer. CONCLUSION: Thromboembolic problems in the morbidly obese before bariatric surgery are infrequent, and screening venous duplex ultrasound can be done in high-risk patients only.

Management of gastric leaks after laparoscopic sleeve gastrectomy for morbid obesity: A tertiary care experience and design of a management algorithm.

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