Bariatric surgery for metabolic unhealthy obesity (MUO) during the COVID era: short-term results of a high-volume center.

PURPOSE: During the coronavirus disease 19 (COVID-19) outbreak, most public hospitals worldwide have been forced to postpone a major part of bariatric surgery (BS) operations with unfavorable consequences for weight and obesity complications. The aim of this study was to evaluate the effectiveness and safety of laparoscopic BS on subjects with metabolically unhealthy obesity (MUO) during COVID-19 pandemic in a high-volume Italian center. METHODS: Between March 2020 and January 2021, all patients with MUO submitted to laparoscopic BS (sleeve gastrectomy [SG], one anastomosis gastric bypass [OAGB] and Roux-en-Y gastric bypass [RYGB]) were enrolled according to the ATP III Guidelines, with a minimum follow-up of 3 months. RESULTS: In the study period, 210 patients with MUO underwent laparoscopic BS (77 RYGB, 85 SG and 48 OAGB) in our obesity referral center. Postoperative major complications occurred in 4 patients (1.9%) with zero mortality. At 9-month follow-up, a total weight loss (TWL) of 28.2 ± 18.4, 26.1 ± 23.1 and 24.5 ± 11.3% (p = 0.042) was observed in RYGB, OAGB and SG groups, respectively. The rate of comorbidity resolution was very similar for all type of surgeries (p = 0.871). Only two cases of postoperative SARS-CoV-2 infection were registered (0.9%) and both cases resolved with medical therapy and observation. CONCLUSION: Among the patients studied, all surgical techniques were safe and effective for MUO during the COVID era. This group of patients is at high risk for general and SARS-CoV-2-related mortality and therefore should be prioritized for BS. LEVEL OF EVIDENCE: Level III, single-center retrospective cohort study.

A pilot study assessing tolerance safety and feasibility of diagnostic transnasal esophagogastroduodenoscopy using an improved larger caliber endoscope and an adapted topical anesthesia.

BACKGROUND: Transnasal esophagogastroduodenoscopy (TN-EGDS) is well tolerated by patients and the examination is perceived comfortable without the need of a sedative drug. Conversely, mainly in Western literature, some authors report limitations in illumination, image quality, and working channel as affecting TN-EGDS diffusion. To overcome these disadvantages, a new transnasal endoscope (TNE) was tested but, due to its larger diameter, we have no evidence of its clinical safety and tolerability. A new adapted nasal anesthesia could be useful to improve TNE tolerance. In an independent, not sponsored, pilot prospective study we enrolled, in a busy clinical hospital setting, 30 adult patients receiving nasal atomized Lidocaine and Xylometazoline (XAL) to undergo a diagnostic TN-EGDS with TNE to evaluate its tolerance, safety, and feasibility. METHODS: Three physicians enrolled inpatients and outpatients with indication to diagnostic EGDS during a 6-month period. Main outcome measures were cardio-pulmonary monitoring data and patients' answers to an adapted questionnaire investigating pain, anxiety level, willingness to repeat the examination, operators' scores about endoscopy quality, examination conduction and anesthesia-related complications. RESULTS: The examination was completed by the transnasal route in 100 % of the enrolled patients, endoscopy satisfaction and feasibility were scored to nearly the highest levels by the three different physicians. A total of 29/30 patients (96.6 %) declared the willingness to repeat the same examination if needed. The mean patients' score for overall pain was 3.7 ± 1 SD (range 1-10 by Visual Analog Scale). Mean endoscopy duration was 11.1 ± 2.6 min (range 5.0-19.0). In a total of 17/30 TN-EGDS that lasted more than 11 min, higher heart frequency variations and worse tolerance scores were found (p < 0.05). CONCLUSION: Our pilot study demonstrates that TN-EGDS with TNE and NA is safe, well tolerated, and feasible. The best clinical tolerance is reached when TN-EGDS lasts <11 min.

Global 30-Day Morbidity and Mortality of Primary Bariatric Surgery Combined with Another Procedure: The BLEND Study.

BACKGROUND: No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures. OBJECTIVES: The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair. SETTING: This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures. METHODS: The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone. RESULTS: A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%). CONCLUSION: Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.

Safety and Efficacy of Laparoscopic Vertical Clip Gastroplasty: Early Results of an Italian Multicenter Study.

PURPOSE: Sleeve gastrectomy, the most commonly performed bariatric surgery procedure, carries limitations both short term including postoperative complications such as hemorrhage and gastric fistula and long term such as weight regain and gastroesophageal reflux. A new procedure has been proposed to overcome many of these limitations: laparoscopic vertical clip gastroplasty (LVCG) with BariClip. MATERIALS AND METHODS: Fifty patients were offered LVCG and enrolled for a feasibility study in two referral bariatric centers. Indication was given as for sleeve gastrectomy, after a multidisciplinary path evaluating age, gender, BMI, comorbidities, eating behaviors, and gastroesophageal reflux. The primary outcome was major postoperative complications. Secondary outcomes included weight loss, incidence of de-novo GERD, and comorbidity resolution. RESULTS: Patients had a mean age of 44 years and mean BMI of 37 kg/m2 ± 6.2. All procedures were performed successfully in laparoscopy, with no conversion or intraoperative adverse events. The overall major postoperative complication rate was 6%. Re-operation was required in three patients for slippage. No mortality occurred. Excess weight loss, excess BMI loss, and total weight loss at 6 months were 36%, 57%, and 22%, respectively. There was no instance of de-novo GERD. Resolution of hypertension occurred in 50% of cases, OSAS in 65% of cases, and DMII in 80% of cases. CONCLUSION: The safety of LVCG procedure has been reproduced in a multicentric, multi-surgeon study. Weight loss outcomes appear promising. A randomized trial is needed to fully assess the benefits of LVCG.

Staple-line reinforcement during laparoscopic sleeve gastrectomy using three different techniques: a randomized trial.

BACKGROUND: The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. The purpose of this study was to compare prospectively and randomly three different techniques of SLR during LSG. METHODS: From April 2010 to April 2011, patients submitted to LSG were randomly selected for the following three different techniques of SLR: oversewing (group A); buttressed transection with a polyglycolide acid and trimethylene carbonate (group B); and staple-line roofing with a gelatin fibrin matrix (group C). Primary endpoints were reinforcement operative time, incidence of postoperative staple-line bleeding, and leaks. Operative time was calculated as follows: oversewing time in group A; positioning of polyglycolide acid and trimethylene carbonate over the stapler in group B; and roofing of the entire staple line in group C. RESULTS: A total of 120 patients were enrolled in the study (82 women and 38 men). Mean age was 44.6 ± 9.2 (range, 28-64) years. Mean preoperative body mass index was 47.2 ± 6.6 (range, 40-66) kg/m². Mean time for SLR was longer in group A (14.2 ± 4.2 (range, 8-18) minutes) compared with group B (2.4 ± 1.8 (range, 1-4) minutes) and group C (4.4 ± 1.6 (range, 3-6) minutes; P < 0.01). Four major complications were observed (3.3 %): one leak and one bleeding in group A; one bleeding in group B; and one leak in group C, with no significant differences between the groups. No mortality was observed. CONCLUSIONS: SLR with either polyglycolide acid with trimethylene carbonate or gelatin fibrin matrix is faster compared with oversewing. No significant differences were observed regarding postoperative staple-line complications.

Laparoscopic Banded One Anastomosis Gastric Bypass: A Single-Center Series.

INTRODUCTION: Laparoscopic one anastomosis gastric bypass (LOAGB) is a relatively new procedure for the treatment of morbid obesity and related comorbidities. On average, this procedure results in good postoperative weight loss with a low complication rate. Recent publications suggest that dumping syndrome and weight regain might be reduced by placing a silicone ring over the gastric pouch during the procedure, so called laparoscopic banded one anastomosis gastric bypass (LBOAGB). METHODS: 86 patients undergoing LBOAGB between 2018 and 2020 were enrolled in this retrospective study. Hospital records were used to assess weight loss, comorbidity resolution, and any complications either in the short or medium term. RESULTS: 54 Female and 32 male patients were included with a mean age of 43 years (25-64), preoperative body mass index of 42 kg/m2 (35-49), and preoperative weight of 114 kg (86-162). Thirty-four patients presented with type 2 diabetes (39.5%), 42 patients (49%) diagnosed with hypertension, 24 presented with OSAS (28%), and 21 (24%) hypercholesterolaemia patients were included. In total, 36 patients were diagnosed with multiple comorbidities. The operative data showed an average operative time of 48 minutes with 3.4% of patients suffering from early (minor) complications and 2.3% with a late (minor) complication. One patient required reoperation due to intra-abdominal bleeding. The median length of hospital stay was 2.5 days. Median follow-up was 18 months (5-36). In that period, no patient required ring removal or conversion to Roux-en-Y gastric bypass surgery. Food intolerance/vomiting was present in 1 patient (1.1%), bile reflux was present in 1 patient (1.1%), and no stomal ulcers were observed. Mean % excess weight loss at 12 and 24 months was 72% and 80%, respectively. Fifty-two out of 86 patients (60%) had a complete resolution of comorbidities. A CONUT score >2 (mild malnutrition) was found in 40% of patients, while a CONUT score 0-1 was found in 60% of patients. CONCLUSION: LBOAGB shows promising results in terms of safety and efficacy in the short term. Further prospective studies will be required to evaluate the consistency of the results in the long term.

Benign Anorectal Disorders and Pelvic Floor Disease After Bariatric Surgery.

The correlations between morbid obesity, bariatric surgery and gastrointestinal disorders are well known and reported. Symptoms like abdominal pain, constipation, bloating, heartburn and gastroesophageal reflux disease are known to be significantly more prevalent in overweight patients and body mass index is associated positively with abdominal pain and diarrhea. In spite of these conditions, less is known about the lower gastrointestinal tract. Of these, anorectal disorders and pelvic floor disease are both believed to be more frequent in obese patients compared to the general population. Weight loss related to bariatric surgery seems to improve quality of life and weight-related symptoms, although some of these conditions may get worse. All these conditions are rarely studied in patients undergoing bariatric surgery for morbid obesity. This concise review aimed to focus on these conditions in patients undergoing bariatric surgery for morbid obesity in order to improve patient selection and post-operative management.

Nutritional Status after Roux-En-Y (Rygb) and One Anastomosis Gastric Bypass (Oagb) at 6-Month Follow-Up: A Comparative Study.

INTRODUCTION: Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) are two effective bariatric surgical procedures with positive outcomes in terms of weight loss, comorbidities remission, and adverse events profiles. OAGB seems to carry a higher risk of malnutrition, but existing data are controversial. The aim of this study is to objectively evaluate and compare malnutrition in patients undergoing RYGB and OAGB. METHODS: Retrospective monocentric study of obese patients undergoing RYGB or OAGB between the 15 September 2020 and the 31 May 2021. Nutritional status was assessed using the Controlling Nutritional Status (CONUT) score and compared between groups. The primary outcome was the mean CONUT score at 6 months. The secondary outcomes included the incidence of malnutrition, comorbidities, including hypertension, insulin resistance and type II diabetes mellitus, and weight loss. RESULTS: 78 patients were included: 30 underwent RYGB and 48 underwent OAGB. At 6-Month Follow-Up there was no difference between groups in the mean CONUT score nor in incidence of malnutrition. In both groups, the nutritional status significantly worsened 6 months after surgery (preoperative and postoperative score of 0.48 ± 0.9 and 1.38 ± 1.5; p = 0.0066 for RYGB and of 0.86 ± 1.5 and 1.45 ± 1.3; p = 0.0422 for OAGB). Type II Diabetes mellitus (DMII) and hypertension remission were significant in the OAGB group with a 100% relative remission in the DMII-OAGB group (p = 0.0265), and a 67% relative remission in the hypertension-OAGB group (p = 0.0031). CONCLUSIONS: No difference in nutritional status has been detected between patients undergoing RYGB or OAGB at the 6-Month Follow-Up. Both procedures may have significant mal-absorptive effects leading to decline in nutritional status. OAGB may be more efficacious in inducing DMII and hypertension remission. Larger prospective studies dedicated specifically to nutritional status after gastric bypass are needed to confirm the impact of different bypass procedures on nutritional status.

Metabolic surgery for type II diabetes: an update.

Bariatric operations have been documented in clinical trials to promote remission or dramatic improvement of Type II Diabetes Mellitus and related comorbidities. Herein we review randomized trials and meta-analyses published during the last 20 years on the results of bariatric/metabolic surgery in obese patients with type 2 diabetes with the aim of highlighting the scientific evidence available. Several studies and RCTs in the last 20 years have showed outstanding results of bariatric/metabolic surgery on Type II diabetes and comorbidities in patients with either BMI > 35 kg/m2 or BMI < 35 kg/m2. They have established that bariatric procedures are superior to non-surgical interventions for inducing weight loss and amelioration of type 2 diabetes, even in patients with a BMI between 30 and 35 kg/m2. The physiopatologic changes that improve glucose homeostasis after bariatric surgery remain unclear but glycemic control is improved after sleeve gastrectomy, duodenal-jejunal bypass, Roux-en-Y gastric bypass, gastric banding, One Anastomosis Gastric Bypass, and biliopancreatic diversion. Nevertheless, it is suggested that the various gastrointestinal procedures may have different effects and mechanisms of action. Metabolic surgery will help integrate knowledge and multidisciplinary expertise to provide a combination of conservative and surgical treatments for Type II diabetes. These treatments must be considered as complementary options and not alternative strategies, with the same goal of controlling diabetes and achieving cure.

Laparoscopic Banded Sleeve Gastrectomy: Single-Center Experience with a Four-Year Follow-Up.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is now the most common bariatric procedure to treat morbidly obese patients. The main concern of LSG lies in the long-term weight regain, which is reported to happen in up to 75.6% of patients after 6 years. In this study, we report our overall experience with Laparoscopic Banded Sleeve Gastrectomy (LBSG) using the MiniMizer® over a 6-year period. Materials and Methods: We performed a retrospective review of data from a prospectively collected database. All patients submitted to primary LBSG were examined. Patients were submitted to LBSG between February 2014 and January 2020. Collected data included demographic factors, preoperative body mass index (BMI), operative time, surgical complications, and clinical outcomes. Results: Two hundred nine patients were submitted to primary LBSG in the study period. They were 136 females (65%) and 73 males (35%) with a median age of 43.0 years (range, 18-65 years). Median preoperative BMI was 48.4 kg/m2 (range, 36.2-65.5 kg/m2). Median operative time was 72.0 minutes (range, 40-142 minutes). Median time for ring placement was 8.0 minutes. Median postoperative hospital stay was 2.8 days. Seven major complications occurred in the postoperative period (3.3%): five gastric leaks (2.3%) and two major bleedings (0.9%). There was no postoperative mortality in the 209 patients. Long-term major complications occurred in 2 patients (0.9%). Median follow-up was 49.2 months (range, 2-72 months). Median postoperative BMI was 29.6 kg/m2 (range, 22-42 kg/m2). Median %excess weight loss (%EWL) at 1 year after surgery was 52.0%. Median %EWL at last follow-up visit was 64.0%. Conclusion: LBSG is as safe as standard LSG with excellent results in terms of postoperative morbidity and weight loss outcomes. Whether this procedure may result superior to standard LSG in the long-term period needs to be evaluated in randomized trials. Clinical Study Registration Number: NCT04354532.

Safety and Outcomes of Laparoscopic Sleeve Gastrectomy in a General Surgery Residency Program.

BACKGROUND: With the escalation of surgical treatment of morbid obesity, there is a growing interest in the training of bariatric surgeons. Laparoscopic sleeve gastrectomy (LSG) gained popularity both as a first-stage approach and as a stand-alone procedure. OBJECTIVES: The aim of this study was to assess detectable differences in LSG with intra-operative resident involvement. METHODS: We reviewed obese patients, who had undergone LSG between January 1, 2017 and January 31, 2020. Collected data reported demographic factors, operative time, postoperative complications, and outcomes. RESULTS: Among 313 patients who met the inclusion criteria, 94 were men and 219 were women. The procedures were performed either by an expert bariatric surgeon (group 1), or a general surgery resident (group 2), respectively in 228 and 85 cases. Mean operative time of the first group was 65.3 ± 18.8 minutes, while it was 74.3 ± 17.2 among trainees (p < 0.001). Perioperative complications were diagnosed in 13 patients (10 in group 1 and 3 in group 2). Mean excess body weight loss after 12 months was 87.7 ± 28.2% in the first group and 81.1 ± 31.6% in the residents group. Between the two groups, we found no differences in the incidence of perioperative complications and in surgical outcomes. Trainee involvement was associated with increased operative time, with no correlation with a worse postoperative course. CONCLUSIONS: Residents can safely perform LSG in referral centers under the supervision of an expert bariatric surgeon. Trainee involvement is not related to increased leak rate, nor to suboptimal short-term outcome.

Banded Sleeve Gastrectomy Improves Weight Loss Compared to Nonbanded Sleeve: Midterm Results from a Prospective Randomized Study.

Background: Weight regain after laparoscopic sleeve gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short term. We report the results of a randomized study comparing LSG and laparoscopic banded sleeve gastrectomy (LBSG) over a 4-year follow-up. Objectives: To evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the midterm. Methods: Between 01/2014 and 01/2015, we randomly assigned 50 patients to receive one of the two procedures. Patients' management was exactly the same, apart from the band placement. We analyzed differences in weight loss, operative time, complication rate, and mortality, with a median follow-up of 4 years. Results: Twenty five patients were assigned to receive LSG (Group A) and 25 LBSG (Group B). The mean preoperative BMI (body mass index) was 47.3 ± 6.58 kg/m2 and 45.95 ± 5.85 kg/m2, respectively. There was no significant difference in the operative time. No intraoperative or postoperative complications occurred. At 12-month follow-up, the mean BMI was 29.72 ± 4.40 kg/m2 in Group A and 27.42 ± 4.47 kg/m2 in Group B (p=0.186). After a median follow-up of 4 years, the mean BMI in Group B was significantly lower than Group A (24.10 ± 4.52 kg/m2 vs 28.80 ± 4.62 kg/m2; p=0.00199). Conclusions: LBSG is a safe procedure, with no impact on postoperative complications. The banded sleeve showed a significant greater weight loss in the midterm follow-up. Considering the issue of weight regain observed after LSG, the placement of a perigastric ring during the first procedure may be a strategy to improve the results. This trial is registered with NCT04228185.

Completely Isolated Enteric Duplication Cyst and Incidental Neuroendocrine Tumor of the Appendix: A Case Report.

BACKGROUND Completely isolated enteric duplication cysts (CIDCs) are rare malformations that can occur at any site in the gastrointestinal system. This report describes a woman with a CIDC and an incidental appendiceal neuroendocrine tumor (ANET). CASE REPORT A 26-year-old woman who presented with dysmenorrhea was assessed by ultrasound (US), which revealed a pelvic mass. Other imaging modalities, including magnetic resonance imaging (MRI), failed to clarify the origin of the mass. Intraoperative findings during diagnostic laparoscopy revealed an isolated, ovaloid mass with autonomous peristalsis and a short pedicle towards the root of the ileal mesentery. In addition, the appendix appeared enlarged with a hardened consistency. The mass was resected and an appendectomy performed laparoscopically. The pelvic mass was diagnosed as a CIDC and the appendix was incidentally found to contain a pT3Nx carcinoid tumor. Based on histological examination and guidelines of the European Neuroendocrine Tumor Network (ENET), the patient later underwent a laparoscopic right hemicolectomy. CONCLUSIONS CIDC in adulthood is very rare, especially when combined with an incidentally discovered pT3Nx appendiceal carcinoid tumor. Neither US nor MRI was able to provide a precise preoperative diagnosis. Diagnostic laparoscopy clarified the nature of the mass and revealed a lesion missed during the preoperative workup. Because of the diagnosis of ANET, the patient subsequently underwent a laparoscopic right hemicolectomy.

Metachronous splenic metastasis from colonic carcinoma five years after surgery: a case report and literature review.

Metastatic lesions of the spleen are a rare finding and are generally associated with widespread disease. Moreover, solitary metastases of the spleen are exceptional. In this paper, we describe the case of a patient who developed an isolated splenic metastasis from colon carcinoma five years after surgery, and was successfully treated by splenectomy. We also review the scant literature experience discussing clinical diagnosis and approaches to this uncommon event.

Iatrogenic rectal perforation during operative colonoscopy: closure with endoluminal clips.

The risk of perforation during diagnostic or operative colonoscopy can be as high as 2%. Despite conservative treatment being acceptable, the closure of the perforation is usually mandatory, and surgery (either open or laparoscopic) is commonly advocated as rescue therapy. Currently, with the availability of the Endoclip, endoscopists are able to manage iatrogenic perforations avoiding surgery. Clip placement, if necessary, will not delay surgery and might help the surgeon find the site of perforation. However, data in the literature are scant, especially for the closure of large colonic defects. Endoscopic repair using Endoclip devices for a large high rectal perforation following polypectomy is described herein.

Laparoscopic reoperative approach after open bariatric surgery.

The aim of the study was to evaluate the laparoscopic approach to reoperative bariatric surgery. From January 2003 to July 2007, 26 obesity surgery patients were referred to our Institution for revision. Nineteen patients previously had an open gastric banding, 3 an open vertical banded gastroplasty, 2 an open jejunoileal by-pass (J-l BP) and 2 an open gastric by-pass. Indications for re-operation were insufficient weight loss in 14 patients, band slippage in 7, band erosion in 3 and severe malabsorptive syndrome in 2. Mean preoperative BMI was 45 kg/m2. Twenty-six laparoscopic re-operative procedures were performed. Three patients required a third operation. Eleven gastric banding patients underwent band removal, 7 gastric banding patients were converted to an open gastric by-pass, 1 band was removed and simultaneously re-placed, the 2 jejuno-ileal by-pass patients underwent an intestinal restoration, 3 vertical banded gastroplasty patients were converted to laparoscopic gastric by-pass, 1 open gastric by-pass patient was converted to a laparoscopic long-limb gastric by-pass and in 1 patient with a gastro-gastric fistula after open gastric by-pass the fistula was resected. Further procedures included 1 laparoscopic gastric banding, 1 laparoscopic gastric bypass and 1 laparoscopic bilio-pancreatic diversion. Conversion to laparotomy was needed in 5 cases (5/29, 17.2%). Early complications included 1 case of pneumothorax and 6 cases of wound infection (24.1%). Mortality was zero. The mean follow-up was 36.2 months. Mean postoperative BMI was 34.3 kg/m2. Laparoscopic reoperative bariatric surgery is feasible, safe and effective after open bariatric surgery.

Laparoscopic versus open ileo-colonic resection in Crohn's disease: short- and long-term results from a prospective longitudinal study.

Possible relations between surgical approaches, frequency, and severity of Crohn's disease recurrence after ileo-colonic resection is unknown. We aimed to assess perioperative outcomes and postsurgical complications of laparoscopic versus standard open surgery and to detect differences between the two groups in endoscopical recurrence and patients' satisfaction. Twenty-eight consecutive patients undergoing elective ileo-colonic resection by either laparoscopic approach (n = 15) or conventional open surgery (n = 13) were prospectively enrolled. No mortality or major intraoperative complications were observed in both groups. Significant differences between groups were the median operating time found shorter in the open group than in the laparoscopic group (p = 0.003), the higher dosage of pain killers needed in the open group (p = 0.05), the passage of flatus and\or stool after surgery found faster in group A (p = 0.004) and the shorter recovery period in the laparoscopic group (p = 0.007). Colonoscopy was performed in 27 patients. The frequency and pattern of recurrence did not differ between the two groups (p = 0.63). Patients' satisfaction was significantly in favor of laparoscopy. Present findings support the feasibility and advantages in the short-term of laparoscopic ileo-colonic resection in patients with Crohn's disease. No differences were observed in terms of frequency, time of onset, and severity of recurrence in a 1-year follow-up.

Integrated Approaches for the Management of Staple Line Leaks following Sleeve Gastrectomy.

Introduction. Aim of the study was trying to draw a final flow chart for the management of gastric leaks after laparoscopic sleeve gastrectomy, based on the review of our cases over 10 years' experience. Material and Methods. We retrospectively reviewed all patients who underwent LSG as a primary operation at the Bariatric Unit of Tor Vergata University Hospital in Rome from 2007 to 2015. Results. Patients included in the study were 418. There were 6 staple line leaks (1.44%). All patients with diagnosis of a leak were initially discharged home in good clinical conditions and then returned to A&E because of the complication. The mean interval between surgery and readmission for leak was 13,4 days (range 6-34 days, SD ± 11.85). We recorded one death (16.67%) due to sepsis. The remaining five cases were successfully treated with a mean healing time of the gastric leak of 55,5 days (range 26-83 days; SD ± 25.44). Conclusion. Choosing the proper treatment depends on clinical stability and on the presence or not of collected abscess. Our treatment protocol showed being associated with low complication rate and minor discomfort to the patients, reducing the need for more invasive procedures.

Laparoscopic Sleeve Gastrectomy versus Laparoscopic Banded Sleeve Gastrectomy: First Prospective Pilot Randomized Study.

Introduction. The placement of ring or band around the gastric tube might prevent the dilation after Laparoscopic Sleeve Gastrectomy (LSG). We describe the first randomized study comparing LSG and Laparoscopic Banded Sleeve Gastrectomy (LBSG). Material and Method. Fifty obese patients were enrolled in the study between January 2014 and January 2015. We analysed differences in operative time, complication rate, mortality, and BMI between the two groups over a period of 12 months. Results. Twenty-five patients received LSG (group A) and 25 LBSG (group B). The mean preoperative BMI was 47.3 ± 6.58 kg/m(2) and 44.95 ± 5.85 kg/m(2), respectively, in the two groups. There was no statistical relevant difference in operative time. No intraoperative complications occurred. Mean BMI registered after 3, 6, and 12 months in groups A and B, respectively, were 37.86 ± 5.72 kg/m(2) and 37.58 ± 6.21 kg/m(2) (p = 0.869), 33.64 ± 6.08 kg/m(2) and 32.03 ± 5.24 kg/m(2) (p = 0.325), and 29.72 ± 4.40 kg/m(2) and 27.42 ± 4.47 kg/m(2) (p = 0.186); no statistical relevant difference was registered between the two groups. Conclusion. LBSG is a safe and feasible procedure. The time required for the device positioning did not influence significantly the surgical time. The results of bodyweight loss did not document any statistically significant differences among the two groups, even though LBSG group showed a mean BMI slightly lower than that of the control group.

Gender Influence on Long-Term Weight Loss and Comorbidities After Laparoscopic Sleeve Gastrectomy and Roux-en-Y Gastric Bypass: a Prospective Study With a 5-Year Follow-up.

BACKGROUND: Gender might be important in predicting outcomes after bariatric surgery. The aim of the study was to investigate the influence of gender on long-term weight loss and comorbidity improvement after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: A cohort of 304 consecutive patients underwent surgery in 2006-2009: 162 (98 women, 64 men) underwent LSG and 142 (112 women, 30 men) underwent LRYGB. The mean follow-up time was 75.8 ± 8.4 months (range, 60-96 months). RESULTS: Overall mean (95% CI) reduction in BMI was 23.5 (24.3-22.7) kg/m(2) after 5 years, with no statistical difference between LSG and LRYGB groups (P = 0.94). The overall means ± standard deviations of %EBMIL after 5 years were 78.8 ± 23.5 and 81.6 ± 21.4 in the LSG and LRYGB groups, respectively. Only for LSG group %EBMIL after 24-36 and 60 months differed significantly between male and female patients (P = 0.003 versus P = 0.06 in LRYGB), and 89 versus 90% of patients showed improvements in comorbidities in the LSG and LRYGB groups, respectively. Only two patients (women) were lost to follow-up: 1/162 (0.6%) for LSG at the 4th year and 1/142 (0.7%) for LRYGB to the 5th year. CONCLUSIONS: LSG was more effective in obese male than in female patients in terms of %EBMIL, with no difference in comorbidities. LRYGB elicited similar results in both genders in terms of %EBMIL and comorbidities.
