RESULTS 352 patients were included in this study (UC = 26587). There was no significant difference in vital signs and biochemistry results in both groups. There was no significant difference in VFA, SFA, V/S ratios in both groups. In patients with V/S ratio > 0.4, they were 5.06 times more likely to undergo emergency intervention (95% CI 1.10-23.45) (p = 0.03). On multivariate analysis, a heart rate > 100 (OR 2.9, 95% CI 1.2-6.7), CRP > 50 (OR 3.4, 95% CI 1.9-6.0), WCC  0.4 (OR 2.8, 95% CI 1.5-5.4) were predictive of complicated diverticulitis. CONCLUSION The quantitative radiological measurement of visceral adiposity is useful in prognostication in patients presenting with diverticulitis.BACKGROUND Anastomotic leak (AL) is the most feared complication in colorectal surgery. Indocyanine green (ICG) fluorescence angiography allows for real-time intraoperative evaluation of bowel perfusion. find more This study aimed to assess the impact of ICG on perioperative outcomes in patients treated with transanal total mesorectal excision (TaTME) for rectal cancer. METHODS Comparative study based on a retrospective analysis of prospectively collected data, to validate the use of ICG assessment (ICGA) during TaTME (November/2011-June/2018). The primary outcome was the clinical AL rate. The secondary outcomes included modification of proximal colonic transection, anastomotic redo, additional surgical maneuvers and surgical morbidity. RESULTS Two hundred and eighty-four patients were included, 204 (71.8%) in non-ICG group and 80 (28.2%) in ICG group. No significant differences were found in patient and tumor features. Mean anastomotic height was 4.85 cm vs. 5.04 cm (p = 0.500), diverting stoma was constructed in 205 patients (72.1% vs. 72.5%; p = 0.941). Fluorescence angiography modified the surgical plan in 23 patients (28.7%). AL was diagnosed in 23 patients (11.3%) in the non-ICG group and in two patients (2.5%) in the ICG group (p = 0.020). Postoperative intraabdominal collection was diagnosed in 19 patients (7.4% vs. 5.1%; p = 0.490), and reintervention was needed in 24 patients (10.8% vs. 7.6%; p = 0.420). Median length of hospital stay was 6.0 (IQR 5.0-9) vs. 4.0 (IQR 3.0-8.5) (p = 0.005). ICGA was found as independent protective factor for AL in the multivariate analysis of the whole cohort (n = 284) (OR 0.142; 95% CI 0.032-0.633; p = 0.010). CONCLUSION ICG fluorescence angiography modified the proximal colonic transection in more than one-quarter of patients, leading to a significant decrease of AL rate.BACKGROUND Despite significant advances in imaging and genetics, as well as surgical and anesthetic innovations, morbidity in pheochromocytoma surgery remains significant. The aim of this study was to identify the predictive factors of global and cardiovascular morbidity following unilateral laparoscopic adrenalectomy for pheochromocytoma. METHODS We conducted a retrospective study from a unicentric cohort. All patients who underwent non-converted laparoscopic unilateral adrenalectomy for pheochromocytoma between 2000 and 2017 were included. Our patients did not systematically benefit from preoperative pharmacological preparation. It is to be noted that they never received alpha-blockers. Preoperative, intraoperative, and postoperative data during follow-ups were collected. Univariate and multivariate analyses by logistic regression were performed. RESULTS A total of 134 patients were included. Fifty-three percent of patients did not receive preoperative pharmacological preparation (PPP) and 33% neither preop. This also allows us to better prevent and anticipate their possible complications.BACKGROUND The present study aimed to compare the outcome of single anastomosis sleeve ileal (SASI) bypass and sleeve gastrectomy (SG) in regards weight loss, improvement in comorbidities at 12 months of follow-up, and postoperative complications. METHODS This was a case-matched, multicenter analysis of the outcome of patients who underwent SG or SASI bypass. Patients who underwent SASI bypass were matched with an equal number of patients who underwent SG in terms of age, sex, BMI, and comorbidities. The main outcome measures were excess weight loss (EWL) at 6 and 12 months after surgery, improvement in medical comorbidities, and complications. RESULTS A total of 116 patients (97 female) of a mean age of 35.8 years were included. Fifty-eight patients underwent SASI bypass and an equal number underwent SG. %EWL at 6 months postoperatively was similar between the two groups. SASI bypass conferred significantly higher %EWL at 12 months than SG (72.6 Vs 60.4, p  less then  0.0001). Improvement in type 2 diabetes mellitus (T2DM) and gastroesophageal reflux disease (GERD) after SASI bypass was better than SG (95.8% Vs 70% and 85.7% Vs 18.2%, respectively). SASI bypass required longer operation time than SG (108.7 Vs 92.8 min, p  less then  0.0001). Complications occurred in 12 (20.7%) patients after SG and 4 (6.9%) patients after SASI bypass (p = 0.056). CONCLUSION The %EWL at 12 months after SASI bypass was significantly higher than after SG. SASI bypass conferred better improvement in T2DM and GERD than SG. Both procedures had similar weight loss at 6 months postoperatively and comparable complication rates.BACKGROUND AND AIMS Double balloon enteroscopy (DBE) has revolutionised the diagnosis and treatment of small bowel (SB) conditions. However, deep SB insertion can be challenging in patients with a history of abdominal surgery and a two-step procedure is required when findings are not amenable to endoscopic therapy. This case series reports the development of laparoscopically assisted DBE (LA-DBE) using single incision laparoscopic surgery (SILS). METHODS Retrospective review of LA-DBE procedures performed in a single tertiary centre over 6 years. RESULTS Seventeen patients (median age 40 years, male 41%) underwent 17 LA-DBE procedures. The approach was oral in 13 and rectal in 4. Laparoscopic approach was standard (multi-port) in the first four cases, SILS was then used in all subsequent patients (13/17). Indications for LA-DBE were previously failed standard DBE (n = 16) and need for a combined procedure (n = 1). Indications for DBE were Peutz-Jeghers syndrome (PJS) (n = 10), suspected submucosal/polypoid lesion at small bowel imaging (n = 5) and obscure gastrointestinal bleeding (OGIB) with vascular abnormalities seen at capsule endoscopy (n = 2). In 1/17 the suggested pathology on imaging was not identified. Therapy was applied in 15/17 (88%) cases. Diagnoses were PJS polyps (n = 8), neuroendocrine tumour (NET) (n = 2), PJS and NET (n = 1), transmural arteriovenous malformation (n = 1), angioectesia (n = 1), inflammatory polyp (n = 1), leiomyoma (n = 1) and Meckel's diverticulum (n = 1). The median (range) procedure time was 147 (84-210) mins. Median (range) length of stay post-procedure was 2 (1-19) days. Three patients developed complications. The 30-day mortality rate was 0%. CONCLUSIONS LA-DBE is a safe, effective and minimally invasive procedure that can be applied for the management of selected patients with small bowel pathology. A SILS approach allows all therapeutic modalities to be available, including conversion to intraoperative enteroscopy (IOE), laparoscopic small bowel resection and laparotomy.BACKGROUND A history of abdominal biliary tract surgery has been identified as a relative contraindication for laparoscopic common bile duct exploration (LCBDE), and there are very few reports about laparoscopic procedures in patients with a history of abdominal biliary tract surgery. METHODS We retrospectively reviewed the clinical outcomes of 227 consecutive patients with previous abdominal biliary tract operations at our institution between December 2013 and June 2019. A total of 110 consecutive patients underwent LCBDE, and 117 consecutive patients underwent open common bile duct exploration (OCBDE). Patient demographics and perioperative variables were compared between the two groups. RESULTS The LCBDE group performed significantly better than the OCBDE group with respect to estimated blood loss [30 (5-700) vs. 50 (10-1800) ml; p = 0.041], remnant common bile duct (CBD) stones (17 vs. 28%; p = 0.050), postoperative hospital stay [7 (3-78) vs. 8.5 (4.5-74) days; p = 0.041], and time to oral intake [2.5 (1opic surgery.BACKGROUND Bleeding control as one of the major challenges in laparoscopic pancreaticoduodenectomy (LPD) necessitates a considerable anatomical knowledge of the blood supply to the pancreatic head so as to improve the safety of this surgery. This study aimed towards a better understanding of the anatomical features of the dorsal pancreatic artery (DPA), as well as its clinical significance in LPD. METHOD Thirteen Chinese cadaveric specimens were used to study the blood supply of the pancreatic head. Twelve of them were perfused with latex, and the other fresh one was used to build the intraorganic structure model of the pancreas by mold casting. Between July 2018 and June 2019, a total of thirty-five consecutive patients without vascular encasement, who underwent LPD in our institute, were performed with computed tomography as a preoperative detection of the DPA. The DPA was ligated prior to uncinate process dissection in seventeen patients ("early DPA ligation" group), as the others were assigned into the control group. RESULTS In the thirteen cadaveric specimens, the DPA originates, respectively, from the splenic artery (46.1%), superior mesenteric artery (38.5%), common hepatic artery (7.7%) and right gastroepiploic artery (7.7%). The right branch of the DPA gives off terminal arteries to form an "inner ring" in the pancreatic head, which communicates with the pancreaticoduodenal arterial arches by plenty of collateral arteries. As compared to the control group, the "early DPA ligation" group showed a significantly lower mean blood loss (218 ± 111 vs 320 ± 162, P = 0.038), as well as shorter mean resection time (121 ± 23 vs 136 ± 22, P = 0.049). CONCLUSION The DPA is one of the major blood supplies to the pancreatic head. A ligation of DPA prior to dissection of the uncinate process can help to completely block the blood supply to the pancreatic head, and therefore improve surgical outcome and safety in LPD.BACKGROUND Accurate identification of tumor sites during laparoscopic colorectal surgery helps to optimize oncological clearance. We aimed to assess the timing of the local injection preoperatively and clarify the usefulness and limitation of tumor site marking using indocyanine green (ICG) fluorescence imaging. METHODS Consecutive patients who underwent primary colorectal cancer surgery from September 2017 to January 2019 were included. Preoperatively, lower endoscopy was used to inject the ICG solution into the submucosal layer near the tumor. During laparoscopic surgery, ICG fluorescence marking as the tumor site marking was detected using a laparoscopic near-infrared camera system. The detection rate and factors associated with successful intraoperative ICG fluorescence visualization including the interval between local injection and surgery were evaluated. RESULTS One hundred sixty-five patients were enrolled. Using the laparoscopic near-infrared system, the intraoperative detection rates of ICG marking were 100% for ICG injection within 6 days preoperatively, 60% for injection between 7 and 9 days preoperatively, and 0% for injection earlier than 10 days preoperatively.
