“…However, it is still done at our center for complications like bleeding ulcers. The most common complication following GJ is stenosis, followed by marginal ulcers and perforation [3]. Gastric remnant cancer (GRC) is the gastric carcinoma that develops in the remnant stomach more than five years after distal gastrectomy for benign disease [4][5][6][7].…”

Gastric adenocarcinoma is the fifth most common cancer worldwide and the third leading cause of death. The major risk factors include Helicobacter pylori infection, genetic factors, environmental factors, and atrophic gastritis. Gastric remnant cancer is gastric carcinoma that develops in the remnant stomach more than five years after distal gastrectomy for benign disease, incidence ranging from 1% to 8%. However, gastric carcinoma after loop gastro-jejunostomy without gastric resection for benign etiology is rare. We report a case of a 45-year-old lady with gastro-jejunostomy without gastric resection done in childhood, presenting with adenocarcinoma at the anastomotic site after 35 years.

“…The assumption was based on a combination of two different factors. First, most surgeons calibrate the stoma size using standardized Fouchet bougies or circular staplers [21,22]. Therefore, patients are discharged from surgery with small and standardized GJAs.…”

Long-term follow-up after transoral outlet reduction following Roux-en-Y gastric bypass: Back to stage 0?

et al. 2023

Background and study aim: Significant weight regain affects up to a third of patients after Roux-en-Y Gastric Bypass (RYGB) and demands treatment. The transoral outlet reduction (TORe) with Argon Plasma Coagulation (APC) alone or APC plus full-thickness suturing TORe (APC-FTS) is effective in the short. However, no study has investigated the course of the gastrojejunostomy (GJ) or quality of life (QOL) data after the first post-procedural year. Patients and methods: Patients eligible for a 36-month follow-up visit after TORe underwent upper GI endoscopy with measurement of the GJ and answered QOL questionnaires (RAND-36). The primary aim was to evaluate the long-term outcomes of TORe, including weight loss, QOL, and GJA size. Comparisons between APC and APC-FTS TORe were a secondary aim. Results: Among 39 eligible patients, 29 returned for the 3-year follow-up visit. There were no significant differences in demographics between APC and APC-FTS TORe groups. At 3 years, patients from both groups regained all the weight lost at 12 months, and the GJ diameter was similar to the pre-procedure assessment. As to QOL, most improvements seen at 12 months were lost at 3 years, returning to preprocedural levels. Only the energy/fatigue domain improvement was kept between the one and 3-year visits. Conclusions: Obesity is a chronic relapsing disease. Most effects of TORe are lost at 3 years, and redilation of the GJA occurs. Therefore, TORe should be considered an iterant rather than a one-off procedure.

Modelling side to side intestinal anastomosis

et al. 2017

Side-to-side intestinal anastomosis is a surgical procedure where an incision is performed between two parallel segments of gut and then they are sutured together. The purpose of this paper is to investigate if the standard surgical practice diameter used in anastomosis leads to undesirable closed circulatory flows which may be harmful to the gut tissue. A finite element model for the chyme flow in a side by side anastomosis with realistic user configurable parameters is developed and solved in a wide range of situations. We analyze the flow crossing the anastomosis, the normalized pressure difference in the gut section and the streamlines that show the presence or absence of closed flow regions for a set of surgically feasible anastomosis diameter values. In contrast with the findings of simpler analytical models, closed flows do not appear in any of these cases. The study shows that the current standard surgical practice where the anastomosis diameter is similar to the gut diameter does not lead to undesirable effects predicted by some simple analytical models.
