Adenocarcinoma of the pouch after silastic ring vertical gastroplasty.

A 52-year-old woman was admitted because of epigastralgia, anorexia and recently increased vomiting, 2 years after silastic ring vertical gastroplasty. On gastroscopy, a tumor mass was visualized in the pouch near the "neo-pylorus". Biopsies confirmed adenocarcinoma. She underwent total gastrectomy, and has no evidence of recurrence at 1 year. The literature on gastric carcinoma after gastroplasty is reviewed.

Erosion of Marlex band and silastic ring into the stomach after gastroplasty: endoscopic recognition and management.

We report three patients who developed erosion of a Marlex band or a silastic ring that was used to reinforce the stoma after vertical stapled gastroplasty. The patients were symptomatic and the diagnosis was made by endoscopy. After endoscopic removal of the foreign body, symptoms resolved in two patients. To our knowledge, this is the first report of successful removal, by endoscopy, of an eroding mesh or a ring.

Results of silastic ring vertical gastroplasty more than 6 years after surgery: analysis of a cohort of 214 patients.

BACKGROUND: Among the different techniques of surgical treatment for morbid obesity, silastic ring vertical gastroplasty (SRVG) is an alternative, effective and easily reproducible technique. The aim of this study is to evaluate a cohort of patients >6 years after SRVG for morbid obesity. METHODS: From 1991 to 1996, 273 consecutive patients were eligible for SRVG. The evaluation criteria included weight loss, evolution of co-morbidities, long-term morbidities, satisfaction of patients and quality of life. RESULTS: Among these 273 patients, 1 patient died in the postoperative period (0.4%). Postoperative morbidities occured in 27 patients (10%). The long-term follow-up involved 213 patients (78%). Late postoperative complications consisted of outlet stoma stenosis (14%), staple-line dehiscence (5.6%) and incisional hernia (8.5%). 23 patients (10%) needed a re-do operation. Co-morbidities drastically improved. BMI fell from 45.3 to 30.7. Failure of SRVG was statistically associated with male gender and super-obese patients. 69% of the patients were satisfied, and 73% would recommend this operation. CONCLUSION: SRVG is very effective in a selected group of morbidly obese patients.

Psychological and demographic predictors of successful weight loss following silastic ring vertical stapled gastroplasty.

To identify psychological factors involved in obesity 45 individuals (40 women and 5 men), ranging in age from 21 to 54 years (M age = 41 yr.), who were candidates for silastic ring vertical stapled gastroplasty were assessed on the Millon Behavioral Health Inventory and the Millon Multiaxial Clinical Inventory-III. In addition, a number of demographic variables such as education, marital status, and age of onset of obesity were considered. Analysis indicated that significant predictors of weight loss at a 6-mo. postoperative assessment include age of onset of obesity and scores on the Schizoid scale of the Millon-III. These findings may be of assistance in identifying personality variables associated with changes in weight if replicated in a larger sample.

Conversion of Jejunoileal Bypass to Silastic Ring Vertical Gastroplasty.

A gastric restrictive procedure is usually performed simultaneous with takedown of a jejunoileal bypass (JIB) to prevent weight regain. However, the preferred gastric restrictive procedure has not been established. Currently, we combine JIB takedown with silastic ring vertical gastroplasty (SRVG), and report our experience with 36 patients treated over a 5-year period. Indications for JIB takedown were diarrhea (69%), arthralgias (53%), liver disease (34%), nephrolithiasis (25%), and increasing weight (33%). Mean weight at the time of JIB takedown was 232+/-12 (SEM) lb (105 +/- 5 kg) (77 +/- 8% EBW (excess body weight)). Follow-up was complete in 33 (92%) patients. Post-reversal weight was 202 +/- 14 lb (92 +/- 6 kg) (55 +/- 8% EBW) at 1 year and 218 +/- 12 lb (99 +/- 5 kg) (67 +/- 8% EBW) (not significant) at a mean follow-up of 2.9 years. Twenty-one (64%) patients lost weight or were stable (+/-% EBW), while 12 (36%) gained a mean of 39 +/- 7 lb (18 +/- 3 kg) (range 16-80 lb (7 +/- 36 kg)). Resolution of preoperative complaints was noted in all patients with diarrhea and 53% with migratory arthralgias. Major early postoperative morbidity occurred in 11%, with no mortality. We conclude that SRVG is a safe and effective procedure to combine with JIB takedown.

Necrotizing Sialometaplasia after Silastic Ring Vertical Gastroplasty: Case Report and Review of Literature.

Necrotizing sialometaplasia (NS) is a self-limiting benign condition of unknown origin that affects mainly the minor salivary glands on the hard palate. In its clinical and histological appearance, it mimics malignancy. This report presents a patient with NS who suffered from frequent bouts of vomiting subsequent to silastic ring vertical gastroplasty which resulted in remarkably low pH of the oral cavity. The literature pertaining to NS appearing in conjunction with gastrointestinal disorders was reviewed, and the possible contribution of recurrent emesis to the pathogenesis of NS is discussed.

Gastric Mucosal Changes following Gastroplasty: A Comparative Study Between Vertical Banded Gastroplasty and Silastic Ring Vertical Gastroplasty.

BACKGROUND: Long-term changes of gastric mucosa following surgery for morbid obesity have never been studied, to the best of our knowledge. As 31 patients in our series presented with various gastrointestinal complaints following surgery, we used this opportunity to study mucosal changes. METHODS: Thirty-seven gastroscopies were performed on 31 patients, 20 patients following Vertical Banded Gastroplasty (VBG) and 11 patients following Silastic Ring Vertical Gastroplasty (SRVG) with various gastrointestinal complaints. Macroscopic appearance of the gastric mucosa was examined and biopsies taken from the proximal gastric pouch, the transitional zone and distal stomach. RESULTS: In most patients, macroscopic appearance of the proximal and distal pouches was normal. Pathological findings were mainly located in the transitional zone and were found mainly in the VBG group. CONCLUSIONS: This study indicates that damage to the gastric mucosa is related to the surgical technique, and mainly to the strip of mesh used in the VBG patients. Since hyperplasia and metaplasia were among the microscopic findings, a question is raised about the possibility of malignant transformation. We suggest that routine post-operative gastroscopies be considered, especially following VBG.

Gastric Emptying Half-time Following Silastic Ring Vertical Gastroplasty: A Scintigraphic Study (Preliminary Results).

BACKGROUND: The mechanism for weight loss following gastroplasty surgery is unknown. A few studies have checked gastric emptying patterns following gastroplasty, but none have analyzed their pattern over time. METHODS: Gastric emptying half-time of Tc-99 phytate-labeled semi-solid meal was studied in 23 obese non-diabetic and one diabetic patient (BMI 34.6-55.7). Gastric emptying was measured by gamma scintigraphy before Silastic Ring Vertical Gastroplasty (SRVG) and 1, 3 and 6 months following surgery. RESULTS: Gastric emptying half-times were maximal in all areas of the stomach 1 month after operation, declined to base-line 3 months following the procedure, and showed statistically significant delay in the upper area of the stomach 6 months after the operation. No correlation was found between the delay in food passage following surgery and loss of weight. CONCLUSIONS: Prolongation of gastric emptying half-time following surgery may be a result of two separate mechanisms: asymptomatic or early inflammatory processes in the ring area and pouch distention as a result of partial denervation.

Prospective randomized, controlled study of postoperative pain after titanium silicone rubber clip or Silastic ring tubal occlusion.

OBJECTIVE: To determine if laparoscopic sterilization using the Filshie clip causes less postoperative pain as compared to the Falope ring during the first 24 h after surgery. STUDY DESIGN: Forty subjects were enrolled. Five milliliters of 0.5% bupivicaine was injected at each of the two incision sites and 5 mL was dripped onto each fallopian tube. Subjects then received one Filshie clip and Falope ring on opposite fallopian tubes; the side of occlusion was randomized. Subjects were questioned about pain prior to the first administration of analgesics postoperatively, 1 and 2 h after surgery, at discharge, and 24 h after surgery. RESULTS: Forty subjects completed the study; 32 without major deviations from protocol. There was no significant difference in pain between sides with the Filshie clip or Falope ring at any times evaluated. CONCLUSION: There was no significant reduction in the postoperative pain associated with the Filshie clip as compared to the Falope ring within 24 h after surgery.

Silastic ring vertical gastroplasty- long-term results and complications.

BACKGROUND: Silicone ring vertical gastroplasty (SRVG) in some reports is associated with significant morbidity and a tendency to regain weight in the late postoperative period. The present study aims to evaluate our long-term results, along with early and late postoperative complications. METHODS: The early and late postoperative complications of 300 patients undergoing SRVG and followed for an average of 3.2 years, were reviewed retrospectively. The pre- and post-operative weight and body mass index (BMI) were recorded in a subgroup of 131 patients with an average follow-up of 5.2 years. RESULTS: Early postoperative complications occurred in 99 patients (33.1%), with mortality of one patient (0.3%). Vomiting was the most common late complication, occurring in 49.3%. Re-operation was performed in 19.7% of the patients, mostly for the repair of postoperative ventral hernia. Long-term results following SRVG showed a decrease in weight from 131 +/- 25 kg to 94 +/- 23.2 kg, and BMI decreased from 46.1 +/- 8.1 kg /m(2) to 32.9 +/- 7.4 kg/m(2). Excess body weight loss was 58.5 +/- 39.8%. CONCLUSIONS: Most patients (76%) reported their satisfaction following SRVG. Long-term results revealed a significant and sustained weight loss, mild complications and low mortality rate.

Prospective comparative evaluation of stapled versus transected silastic ring gastric bypass: 6-year follow-up.

BACKGROUND: The effect of transecting vs. stapling the stomach in continuity in the banded gastric bypass (GBP) operation was studied. METHOD: 50 patients, 25 in each group, were enrolled into a prospective study to determine if transecting the stomach vs. stapling it in continuity in performing GBP for obesity decreases the incidence of gastro-gastric fistula formation without increased morbidity. RESULTS: The patient profiles in the 2 groups were very similar. The peri-operative complications included 1 splenic capsular injury in each group, controlled without a splenectomy. There was 1 anastomotic leak in the stapled and 1 bleeding from the cut edge of the bypassed stomach in the transected group, both requiring re-operations in the immediate postoperative period. There was no peri-operative mortality. The percent follow-up after 6 years was 80% and 88% in the stapled and transected groups respectively. The incidence of late complications of solid food intolerance, ventral incisional hernia, cholelithiasis and small bowel obstruction was similar in both groups. There were 8 gastro-gastric fistulas in the stapled group and 1 in the transected group. The reduction in body mass index and percent excess weight loss (66%) were similar in both groups. CONCLUSION: The incidence of gastro-gastric fistula may be reduced in GBP procedures by transecting the stomach as opposed to stapling it in continuity, without an increase in morbidity or mortality or any loss in the effectiveness of the operation.

Massively bleeding gastric pouch ulcer after silastic ring vertical gastroplasty successfully treated endoscopically: a report of two cases.

Two patients who developed massive bleeding from a gastric pouch ulcer are described. This rare complication occurred during the early postoperative course after silicone ring vertical gastroplasty (SRVG). In both cases the bleeding stopped after the ulcers were injected with epinephrine and alcohol. Both ulcers healed after 1 month of treatment with omeprazole (Losec). The probable etiology of this rare complication is discussed.
