Background: Reports demonstrate laparoscopic colorectal surgery in obese patients is associated with higher conversion to laparotomy and complication rates. While several advantages of robotic-assisted surgery have been reported, outcomes in obese patients have not been adequately studied. Therefore, this study compares outcomes of robotic-assisted surgery in non-obese and obese patients., Methods: A retrospective review of 331 consecutive robotic procedures performed at a single institution between 2009 and 2015 was performed. Patients were divided into non-obese (BMI <30 kg/m 2 ) and obese (BMI ≥30 kg/m 2 ) groups, and were clinically matched by gender, age, and procedure performed. Intraoperative and postoperative complications, operative time, estimated blood loss, and length of stay were examined., Results: Following matching, each group included 108 patients comprised of 50 men and 58 women. Mean BMI was 24.6 ± 3.15 and 36.2 ± 5.67 kg/m 2 (p < 0.0001), and the mean age was 59.2 ± 11.28 years for non-obese patients and 57.1 ± 12.44 for obese patients (p = 0.18). Surgeries included low anterior resection, right colectomy, left colectomy, sigmoid colectomy, excision of rectal endometriosis, total proctocolectomy, APR, subtotal colectomy, ileocecectomy, proctectomy, rectopexy, transanal excision of rectal mass, and colostomy site hernia repair. The mean operative time was 272.69 ± 115.43 and 282.42 ± 120.51 min (p = 0.55), estimated blood loss 195.23 ± 230.37 and 289.19 ± 509.27 mL (p = 0.08), conversion to laparotomy 6.48 and 9.26 % (p = 0.45), and length of stay 5.38 ± 4.94 and 4.56 ± 4.04 days (p = 0.18) for the non-obese and obese groups, respectively. Twenty of the non-obese patients had postoperative complications as compared to 27 of the obese patients (p = 0.30). However, the prevalence of wound complications was higher in obese patients (1.9 vs 9.3 %; p = 0.03)., Conclusion: There is no difference in conversion to laparotomy and overall complication rates in non-obese and obese patients undergoing robotic-assisted colorectal surgery. However, obesity is associated with a higher prevalence of wound complications. Robotic-assisted surgery may minimize conversion to laparotomy and complications typically seen in obese patients due to improved visualization, instrumentation, and ergonomics.

Background: Exercise-related transient abdominal pain (ETAP) is a common entity in young athletes. Most occurrences are due to a "cramp" or "stitch," but an uncommon, and often overlooked, etiology of ETAP is median arcuate ligament syndrome (MALS). The initial presentation of MALS typically includes postprandial nausea, bloating, abdominal pain, and diarrhea, but in athletes, the initial presentation may be ETAP., Methods: We present a case series of three athletes who presented with exercise-related transient abdominal pain and were ultimately diagnosed and treated for MALS. Unlike other patients with median arcuate ligament syndrome, these athletes presented with exercise-induced pain, rather than the common postprandial symptoms. These symptoms persisted despite conservative measures. Work-up of patients with suspected MALS include a computed tomography or magnetic resonance angiography showing compression of the celiac artery with post-stenotic dilation, or a celiac artery ultrasound demonstrating increased velocities (>200 cm/s 2 ) with deep exhalation., Results: All patients underwent a laparoscopic median arcuate ligament release. Postoperatively, there were no complications, and all were discharged home on postoperative day #2. All patients have subsequently returned to athletics with resolution of their symptoms., Conclusion: ETAP is common in athletes and often resolves with preventative or conservative strategies. When ETAP persists despite these methods, alternative causes, including MALS, should be considered. A combination of a thorough history and physical exam, as well as radiographic data, is essential to make the appropriate diagnosis and treatment strategy.

Introduction: Chronic pancreatitis is a painful inflammatory disease that leads to progressive and irreversible destruction of pancreatic parenchyma [1]. A lateral pancreaticojejunostomy, also known as the Puestow procedure, is performed for symptomatic chronic pancreatitis associated with a dilated pancreatic duct secondary to calcifications or strictures [4]. An open approach is used traditionally due to the complexity of the case, and there have only been a handful of laparoscopic case reports [2]. This video depicts a laparoscopic lateral pancreaticojejunostomy for chronic pancreatitis., Methods: A 45-year-old gentleman with a 20-year history of chronic alcohol abuse presented with diffuse abdominal pain. His pain was worse postprandially and associated with loose stools. A computed tomography scan revealed multiple calcified deposits within the body and tail of the pancreas, and a dilated pancreatic duct measuring 1.4 cm with a proximal obstructing calcified stone. A 5-port foregut technique was used, and a 15-cm pancreatic ductotomy was performed with an ultrasonic scalpel. Calcified stones were cleared from the duct, and a roux-en-y pancreaticojejunostomy was performed using a hand-sewn technique., Results: The patient had a relatively uncomplicated hospital course with return of bowel function on postoperative day 4. His patient-controlled analgesic device was discontinued on post operative day 3. He was ambulating, tolerating a regular diet and discharged home on postoperative day 5. At 12- and 26-month follow-up, he remains off narcotics, but still requires 1-2 tabs of pancreatic enzyme replacement per meal. Most importantly, he has not had any alcohol for over 2 years., Conclusion: The two primary goals in treating chronic pancreatitis include long-term pain relief and improvements in quality of life [3]. For patients with chronic pancreatitis and a dilated pancreatic duct, a laparoscopic lateral pancreaticojejunostomy may be an effective approach to decrease pain and improve quality of life.

Background: The association between extraction site location, robotic trocar size, and the incidence of incisional hernias in robotic colorectal surgery remain unclear. Laparoscopic literature reports variable rates of incisional hernias versus open surgery, and variable rates of trocar site hernias. However, conclusions from these studies are confusing due to heterogeneity in closure techniques and may not be generalized to robotic cases. This study evaluates the effect of extraction site location on incisional hernia rates, as well as trocar hernia rates in robotic colorectal surgery., Materials and Methods: A retrospective review of multiport and single incision robotic colorectal surgeries from a single institution was performed. Patients underwent subtotal, segmental, or proctocolectomies, and were compared based on the extraction site through either a muscle-splitting (MS) or midline (ML) incision. Hernias were identified by imaging and/or physical exam. Demographics and risk factors for hernias were assessed. Groups were compared using a multivariate logistic regression analysis., Results: The study included 259 colorectal surgery patients comprising 146 with MS and 113 with ML extraction sites. Postoperative computed tomograms were performed on 155 patients (59.8 %) with a mean follow-up of 16.5 months. The overall incisional hernia rate was 5.8 %. A significantly higher hernia rate was found among the ML group compared to the MS group (12.4 vs. 0.68 %, p < 0.0001). Of the known risk factors assessed, only increased BMI was associated with incisional hernias (OR 1.18). No trocar site hernias were found., Conclusion: Midline extraction sites are associated with a significantly increased rate of incisional hernias compared to muscle-splitting extraction sites. There is little evidence to recommend fascia closure of 8-mm trocar sites.
