Portal vein thrombosis after laparoscopic sleeve gastrectomy: presentation and management

Portal vein thrombosis (PVT) is a serious problem with a high morbidity and mortality, often exceeding 40% of affected patients. Recently, PVT has been reported in patients after laparoscopic sleeve gastrectomy (LSG). The frequency is surprisingly high compared with other abdominal operations.

What is the optimal treatment of superior mesenteric vein/portal vein thrombosis after bariatric surgery? Is SMA-directed t-PA the answer?

Acute thrombosis of the portal vein (PV) and superior mesenteric vein (SMV) is a relatively rare but insidious and potentially lethal abdominal complication. Unlike arterial thrombosis, the clinical line of demarcation is often not distinct for venous thrombosis. However, with the advent of readily available, highly sensitive, specific diagnostic modalities, it is now diagnosed at an earlier stage noninvasively.

Adjustable gastric banded plication versus sleeve gastrectomy: the role of gastrectomy in weight loss

 Laparoscopic adjustable gastric banded plication (LAGBP) is a procedure that has a stomach volume similar to the sleeve gastrectomy (SG). It has shown promising results but has not been adopted widely.

Long-term success and failure with SG is predictable by 3 months: a multivariate model using simple office markers

Despite being the most common surgery in the United States, little is known about predicting weight loss success and failure with sleeve gastrectomy (SG). Papers that have been published are inconclusive. We decided to use multivariate analysis from 2 practices to design a model to predict weight loss outcomes using data widely available to any surgical practice at 3 months to determine weight loss outcomes at 1 year.

Comment on: long alimentary limb duodenal switch (LADS) - a short-term prospective randomized trial

There was no difference in the Laval questionnaire for the quality of life between the 2 groups, but patients with the longer alimentary limb had significantly less gastrointestinal side effects, including annoyance with gas and number of stools a day, which is likely to contribute to a better quality of life. Indeed, patients in the study group complained more about constipation than diarrhea.

A Matched Cohort Analysis of Stomach Intestinal Pylorus Saving (SIPS) Surgery Versus Biliopancreatic Diversion with Duodenal Switch with Two-Year Follow-up

In bariatric surgery, the procedure with the highest average weight loss is the biliopancreatic diversion with duodenal switch (BPDDS). A new simplified duodenal switch called the stomach intestinal pylorus sparing (SIPS) surgery with less malabsorption and one fewer anastomosis claims to have similar outcomes when compared to the BPDDS.

An Analysis of Mid-Term Complications, Weight Loss, and Type 2 Diabetes Resolution of Stomach Intestinal Pylorus-Sparing Surgery (SIPS) Versus Roux-En-Y Gastric Bypass (RYGB) with Three-Year Follow-Up

For many years, the Roux-en-Y Gastric Bypass (RYGB) was considered a good balance of complications and weight loss. According to several short-term studies, single anastomosis duodenal switch or stomach intestinal pylorus sparing surgery (SIPS) offers similar weight loss to RYGB with fewer complications and better diabetes resolution.

The Use of Predictive Markers for the Development of a Model to Predict Weight Loss Following Vertical Sleeve Gastrectomy

Average percent excess weight loss data is commonly discussed preoperatively to guide patient expectations following surgery. However, there is a wide range and variation in weight loss following vertical sleeve gastrectomy (SG). Unfortunately, most surgeons and even fewer patients have heard of using predictive models to help guide their decisions on procedure choice. We have developed a predictive model for SG to help patient choice prior to this major life-changing decision.

Laparoscopic Roux-en-Y gastric bypass reversal for chronic nausea and vomiting using the side-to-side anastomosis

Approximately 25% of Roux-en-Y gastric bypass (RYGB) surgical procedures will eventually fail due to insufficient weight loss, weight recidivism, or complications related to the procedure [1,2]. The reported incidence of anastomotic complications after RYGB ranges from .1% to 23% [3]. The patients who experience an anastomotic complication require an intervention.

Laparoscopic adjustable gastric banding versus laparoscopic adjustable gastric banding with gastric plication: midterm outcomes in terms of weight loss and short term complications

Laparoscopic adjustable gastric banding (LAGB) is a safe procedure with variable outcomes and large standard deviations. LAGB with gastric plication (LAGBP) is a new restrictive procedure that combines the lap band with gastric plication. This procedure, with its mechanism being below the band anatomically, should augment the weaknesses of the lap band: slips and inadequate weight loss.

Safety And Effectiveness Of Single Anastomosis

The first bariatric procedure was the jejunocolic bypass followed by the jejunoileal bypass, which resulted in substantial weight loss but unacceptable life threatening complication rates. These procedures along with several others have fallen out of favor over the years, due to failure rates, health risks, and severe deficiencies. Currently, laparoscopic Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are most commonly performed for surgical treatment of morbid obesity.

Symptomatic gastric diverticulum after gastric imbrication with conversion to sleeve gastrectomy

Laparoscopic gastric imbrication (LGI) helps to promote weight loss by reducing the size of the stomach by plicating the greater curve of the stomach. However, if the stomach is not adequately plicated at the fundus, gastric diverticula occur. In this case the gastric diverticulum became symptomatic (chronic nausea) and necessitated conversion to a laparoscopic sleeve gastrectomy, which resulted in a resolution of the patient’s symptoms.

20 Year Diabetes Resolution after DS

Biliopancreatic diversion (BPD) is a complex bariatric operation requiring meticulous surveillance which has impeded its broad adoption. Improvements in surgical care and technique, better teaching programs, and stringent norms for follow-up have contributed to increased safety of BPD for patients with BMI < 50, achieving better long-term results than other bariatric operations. Here we report 20-year outcomes of 2615 consecutive patients (median 8) having open BPD with duodenal switch (DS) between 1992 and 2010.

Randomized Double-Blinded Trial of Laparoscopic Gastric Imbrication v Laparoscopic Sleeve Gastrectomy at a Single Indian Institution

Currently, there is a debate whether the laparoscopic gastric imbrication (LGI) offers similar weight loss when compared to the laparoscopic sleeve gastrectomy (LSG). On the surface, they seem to offer similar-sized stomachs after the procedures are performed. We chose to perform a randomized double-blinded trial to see if similar-sized pouches result in similar types of weight loss. Our belief was that sleeve gastrectomy would offer at least a 10 % better weight loss over a 3-year period.
