Biliopancreatic Limb Length in One Anastomosis Gastric Bypass: Which Is the Best?

BACKGROUND: The use of one anastomosis gastric bypass (OAGB) is rapidly spreading. Concerns about biliary reflux and malabsorption with consequent nutritional deficits exist, so studies on biliopancreatic limb (BPL) adequate length in OAGB are required to balance excess weight loss in percentage (% EWL), resolution of comorbidities, and nutritional deficit. The purpose was to evaluate, at 2 years after OAGB, the effects of BPL length on weight loss, resolution of comorbidity, and nutritional deficiencies in patients. METHODS: From January 2015 to January 2017, 180 patients were collected into three groups based BPL length: group A, 150 cm; group B, 180 cm; and group C, 200 cm. Aims were to compare %EWL, co-morbidity resolution rates, nutritional parameters, and morbidity/mortality in the three groups. RESULTS: The total number of patients was 180: 60 for each group. One hundred seventy-two (95%) patients attended the 1-year follow-up (group A = 58; group B = 58, group C = 56). One hundred fifty-seven (87%) patients attended the 2-year follow-up (group A = 52 (87%); group B = 53 (88%); group C = 52 (87%)). There was no statistically significant difference in %EWL, %TWL, T2DM, and hypertension resolution rates among the groups. About vitamin deficiency, differences were not statistically significant. Iron and ferritin deficiency rate were statistically significant only between A and C groups. CONCLUSIONS: According to our evidence, standardization of BPL length shorter than 200 cm is suggested, potentially minimizing malnutrition-related outcomes. Our study seems to show that a BPL of 150-180 cm is safe and effective in terms of EWL and comorbidity improvement with low malnutrition effects even in BMI > 50.

Safety and efficacy of prophylactic resorbable biosynthetic mesh in loop-ileostomy reversal: a case-control study.

Loop ileostomy (LI) is a widely used temporary stoma technique. Reversal of LI is generally considered a minor and safe procedure, with very low short-term postoperative mortality and morbidity rates. Complications include incisional hernia (IH), carrying a high probability of surgical repair. Clinical measures to reduce the IH rate warrant consideration. Recent researches suggest the use of a prophylactic non-absorbable mesh to reduce IH rate; however, surgeons are reluctant to implant a permanent foreign material in contaminated operative fields, because of a higher risk of mesh-related complications, infection, seroma, and pain. The aim of the present study is to assess feasibility, potential benefits, and safety of a prophylactic biosynthetic mesh placed during LI reversal. From January 2016 to December 2018, 26 consecutive patients underwent LI reversal positioning a resorbable biosynthetic mesh in an on-lay position [mesh group (MG)]. The mesh used was a GORE BIO-A tissue reinforcement, a biosynthetic mesh composed of a bioabsorbable polyglycolide-trimethylene carbonate copolymer. The MG was matched with 58 patients [control group (CG)], undergoing LI reversal without mesh placement from January 2013 to December 2018. To detect IH, abdominal wall was studied according to clinical and ultrasonographic criteria. Primary endpoint was IH rate on LI site, at 6 and 12 months after stomal reversal. Secondary endpoints included incidence of wound events. Thirty-day morbidity was classified according to Clavien-Dindo score; mortality and length of hospital stay were also collected. Mean follow-up was 15.4 ± 2.3 months (range 12.4-22.0) for MG vs 37.2 ± 26.9 (range 24.9-49.7) for. CG. At 1 year of follow-up, IH rate was lower in MG (n = 1/26 [3.8%]) vs CG (n = 19/58 [32.7%]; P < 0.05). A clinically evident IH was less frequent in MG (n = 0 [0%]) vs CG (n = 13 [68%]; P < 0.05). A radiologic IH was less frequent in MG (n = 1 [3%]) vs CG (n = 6 [31%]; P < 0.05). Stoma site hernia was repaired in 9/19 patients (47%) in CG; no patient of MG has hernia repaired. Incarcerated IH was observed in one patient of CG. No postoperative mortality was reported. Overall postoperative morbidity showed no difference comparing MG and MG (n = 5 [17%] vs n = 15 [19%], respectively; P > 0.05). Surgical site infections (SSI) were treated with antibiotic therapy, no debridement was necessary. Seroma occurred in two patients, one for each group. No statistically significant difference for surgical outcomes was found between the two groups at 30 days. Early results of the present study suggest that an on-lay prophylactic placement of GORE BIO-A tissue reinforcement might lower IH rate at LI site. The procedure seems to be safe and effective, even long-term results and further studies are needed.

Minimal invasive surgery in treatment of liver metastases from colorectal carcinomas: case studies and survival rates.

BACKGROUND: Liver represents the main organ subject to metastases from colorectal tumors. Resections of liver metastases from colorectal cancer have a well-considered therapeutic role underlined by survival of 5 years by approximately 50-60% of surgical cases as is deduced from an analysis of the most recent literature. The objective of surgery is to eradicate the metastases present and obtain a margin free from neoplastic impact of amplitude of approximately 1 cm with residual liver quantity at the end of the intervention that allows the patient to survive. Currently the dimensions and the number of colorectal liver metastases (CRLM) do not limit the hepatectomy. Purpose of this work is to evaluate the survival, according to our case studies of patients treated only with the wedge resection (atypical resection) approximately 1 cm from the margins of metastases. METHODS: In "A. Rizzoli" Lacco Ameno Hospital (Ischia), from 2005 to 2010, 12 liver resections were performed for metastases from colorectal carcinoma with atypical resection. Synchronous surgical treatment with resection of the colorectal carcinoma and metastases was performed in 6 patients, 2 female and 4 male (Group 1). Surgical liver metastasectomy post-colectomy was performed on 6 patients, 3 female and 3 male (Group 2). RESULTS: No patient was treated with chemotherapy. The mortality rate of intraoperative and perioperative infection was in both cases of 0%. Survival:11 patients treated surgically from 2005-2010 with synchronous surgery resection (Group 1) and liver metastasectomy (Group 2) are currently living. One 77-years-old patient died three years after surgery for BPCO. CONCLUSIONS: This result was able to be obtained due to the wedge resection technique routinely used in our Hospital, associated with the indispensable use of intraoperatory ultrasound (IOUS). Significant differences between the synchronous and non-synchronous intervention emerged only regarding the number of days of hospital stay, higher in the first case.

[Multicentre survey of post-surgical infections in Campania (Italy)]. / Multicentre survey of post-surgical infections in Campania (Italy).

The aim of the study was to evaluate the incidence of post-surgical infections and to assess the way of managing antibiotic surgical prophylaxis. The survey was carried out by means of a questionnaire in order to obtain diverse information such as demographics, length of pre- and post-operative hospitalization, type of surgery, intervention duration, possible antibiotic prophylaxis and onset of post-surgical infections also monitored by post-discharge ambulatory controls. Four General Surgery and five Obstetrics and Gynaecology Departments in Campania (southern Italy) participated in the study, which was carried out in the period December 2001-January 2002. Overall, 410 questionnaires were collected referring to as many patients; antibiotic prophylaxis was performed in 385 (93.9%) patients. Antibiotic prophylaxis was generally managed not according to the general principles suggested by the international guidelines either for timing or for its duration or for the route of administration. Substantial differences were also noted in patient selection and antibiotic choice. Surgical site infections were recorded in 0.6% of patients undergoing clean surgery, in 5.3% of patients undergoing clean-contaminated surgery and in 3.2% of those undergoing contaminated surgery. Distant infections occurred in 1.8% and 6.5% in clean-contaminated and contaminated surgery, respectively. The results of the present study suggest the need of a continuous and accurate monitoring of post-surgical infections and the need to adopt appropriate guidelines to improve the management of surgical prophylaxis.
