Background
The anatomical and physiological changes after Roux-en-Y gastric bypass for morbid obesity can lead to severe hyperinsulinemic hypoglycemia with neuroglycopenia in a small percentage of patients. The exact physiologic mechanism is not completely understood. Surgical reversal to the original anatomy and distal or total pancreatectomy are...

The objective of this review is to summarize the findings of published research that investigated the relationship between diabetes mellitus and gastric cancer (GCa) and the potential benefits of metformin on GCa. Related literature has been extensively reviewed, and findings from studies investigating the relationship between diabetes mellitus and...

... Revisional operations, including adhesiolysis and reconstructed jejuno-jejunostomy, were shown to relieve hypoglycemic symptoms [42]. A novel reversion technique proposed by Zorron et al. used one-anastomosis jejunal interposition with gastric remnant resection, which was relatively simple but required studies with larger series [52]. ...
Roux-en-Y gastric bypass (RYGB) is an effective treatment for severe obesity and obesity-related comorbidities. Postprandial hypoglycemia may occur as a long-term complication after RYGB. This study reviews the literature on surgical treatment for intractable post-RYGB hypoglycemia to provide updated information. A search was performed in Embase and PubMed, and 25 papers were identified. Thirteen papers on reversal were included. Resolution of postprandial hypoglycemic symptoms occurred in 42/48 (88%) patients after reversal. Twelve papers on pancreatectomy were included. Resolution occurred in 27/50 (54%) patients after pancreatectomy. The optimal surgical treatment for intractable post-RYGB hypoglycemia has not been defined, but reversal of RYGB seems to be more effective than other treatments. Further research on etiology and long-term evaluation of surgical outcomes may refine treatment options.
... They named this novel surgical technique the "Branco-Zorron switch." 20 The benefits of this technique account for gastric pouch preservation, preventing weight regain and GERD. As compared to a gastro-gastrostomy, the single anastomosis between the alimentary limb and residual antrum decreases the risk of any potential leak. ...
Background. Laparoscopic Roux-en-Y gastric bypass (GBP) is an essential bariatric surgical procedure which is globally performed because of the associated effective weight loss and resolution of metabolic comorbidities, such as diabetes and dyslipidemia. Although some complications may occur, hypoglycemia is a rare complication, which can lead to lethal consequences. We aimed to describe the technical aspects and surgical results after reversal to normal anatomy (RNA). Methods. We conducted a retrospective data analysis including 16 patients who underwent laparoscopic RNA from 2011 to 2018. All data were archived in a prospective database. Previous bariatric surgery and postoperative outcomes were analyzed. Results. Sixteen patients underwent RNA, most of them after GBP, and 15 patients required sleeve gastrectomy. Among them, 80% were women; 5 patients presented with postoperative complications, such as colitis with intra-abdominal collection (n = 1), gastric leak (n = 2) treated with an endoprosthesis, mesenteric venous thrombosis (n = 1), and intra-abdominal bleeding (n = 1). Mean length of hospital stay was 5.93 (3-30). All patients recovered from their initial condition although 3 patients presented with mild hypoglycemia during follow-up. Seven patients regained weight (43.75%), and another 4 developed gastroesophageal reflux disease (25%). Conclusions. These laparoscopic RNA results are acceptable, indicating a clinical improvement in the hypoglycemic syndrome in all patients.
... This can also be done as a sutured anastomosis as outline by Vilallonga et al. [2]. Other laparoscopic techniques have utilized the proximal portion of the Roux limb as a jump graft, Zorron et al. [3] or utilized the distal portion of the Roux limb by relocating it back to its origin and anastomosing it to the distal afferent limb, Gatschet et al. [4,5], (Table 1). ...
This is a case series of seven patients who presented with various complications secondary to gastric bypass and were successfully treated with restoration of gastrointestinal continuity without any major complication by a single surgical team. In-addition to, a literature review of laparoscopic and open techniques utilized successfully in establishing bowel continuity in bypass patients with various complications.
Treatment of medically refractory postprandial hypoglycemia after Roux-en-Y Gastric bypass (RYGB) is often unsuccessful. Various operations have been described with poor results. We describe a novel procedure and retrospective review of 8 patients who underwent Roux jejuno-duodenostomy for postprandial hypoglycemic symptoms refractory to dietary modification and medications. Mean follow-up was 35 months. Complete resolution occurred in two of the patients, marked improvement in four, and no improvement in two. The mean frequency of hypoglycemic symptoms decreased from 30 to 7 episodes per week (p = 0.015). One complication was noted with no mortality. Mean weight decreased postoperatively by 0.8 kg (p = 0.93). Conversion to a Roux jejuno-duodenostomy appears to be a safe and effective treatment with maintenance of post-RYGB weight loss in most such cases.
Associated with the obesity epidemic and the growing number of bariatric surgery procedures being performed worldwide, the incidence of reported complications has increased as well. Among these, the postprandial hyperinsulinemic hypoglycemia (PHH) warrants further attention. This condition is not entirelly understood and is probably underdiagnosed. The PHH is characterized by hypoglycemic symptoms occurring after a meal accompanied by a low plasma glucose value, typically preceded by a high rise in both glucose and insulin concentrations. Patients with PHH have shown increased glucose variability with a rapid increase in glucose absorption into the systemic circulation and an increase in glucose disappearance, with glucose values reaching both the hyperglycemic and hypoglycemic areas. It should be suspected in patients with postprandial adrenergic or neuroglycopenic symptoms after bariatric surgery1.
It was considered most commonly associated with Roux-en Y gastric bypass (RYGB), although it was also described after biliopancreatic diversion (BPD), BPD with duodenal switch2, sleeve gastrectomy, and other surgical procedures which compromises the pylorus and the gastric emptying3. It has not been observed after adjustable gastric banding, an intervention that does not alter the gastrointestinal anatomy4-5.
