Operations on the stomach with a Roux anastomosis]

In order to prevent complications such as reflux gastritis, reflux esophagitis, erosions, ulcers and tumors of the gastric stump the Roux anastomosis was used in 497 patients. Among them there were 194 patients after distal resection of the stomach, 239--after extirpation of the stomach, 45 after vagotomy, antrumectomy, 19 after reconstructive operations on the stomach. These patients had organic complications much more rarely: 3.7% had reflux esophagitis (after resection of the stomach on the short loop and with Brown anastomosis--in 50.5%), 12.5% (85.4%) had reflux gastritis, 3.66% (23.7%) had erosions and ulcers of the gastric stump, 2.1% (21.5%) had polyps and carcinomas of the gastric stump. Postoperative lethality was 3.09 and 7.12%.     

Bile reflux after Roux-en-Y gastric bypass: an unrecognized cause of postoperative pain

BackgroundTo determine, in a private practice, whether symptomatic bile reflux can occur after Roux-en-Y gastric bypass (RYGB) for morbid obesity and the outcome after laparoscopic alimentary (Roux) limb lengthening. Bile reflux as a cause of pain after laparoscopic RYGB has not been previously described. We report on a series of patients with chronic pain after RYGB as a result of bile reflux owing an abnormally short alimentary limb.MethodsA prospective database of patients who underwent revisional surgery to treat symptomatic bile reflux at our center was retrospectively reviewed and analyzed for the onset of symptoms, interval to revision, length of alimentary limb, and outcome after revision.ResultsA total of 16 patients were diagnosed with bile reflux and underwent revisional surgery. The onset of symptoms occurred at 58.3 ± 22.2 months after RYGB. All patients complained of pain, 13 (81.3%) had vomiting, and 7 (43.8%) had dysphagia. Endoscopy was performed in all patients and confirmed the presence of bile in all patients and detected marginal ulceration in 5 (31.3%) and gastritis in 8 (50.0%). At revisional surgery, the mean alimentary limb length was 37.7 ± 12.4 cm (range 20–62 cm). At a mean follow-up of 14.9 months after revision, all patients had reported resolution of their symptoms.ConclusionAlthough previously unreported after RYGB, bile reflux can be an important possible cause of chronic pain. Bile reflux, however, responds favorably to alimentary limb lengthening to 100 cm and was not been seen in patients with an alimentary limb length >62 cm.     

Prospective 14- to 18-year follow-up study after parietal cell vagotomy

One hundred and thirty-five patients underwent elective parietal cell vagotomy for duodenal, pyloric or prepyloric ulcers. The patients were followed prospectively at intervals of 1-3 years in order to detect postvagotomy symptoms and recurrent ulcers; 14-18 years after surgery 106 patients were studied with regard to recurrent ulceration and 84 concerning postvagotomy symptoms. Thirty-two patients (30 per cent) had developed proven recurrent ulcers and a further 9 per cent were suspected of having recurrences. Two patients were reoperated for gastric outlet obstruction and one for bile reflux gastritis. Four patients had severe dyspeptic symptoms and four severe dyspepsia plus dumping. No patient had severe diarrhoea. Forty-three patients were regarded as failures after parietal cell vagotomy. After treatment of these failures 88 per cent of the patients available for subsequent follow-up had satisfactory results. The alternatives to parietal cell vagotomy are discussed. It is concluded that although parietal cell vagotomy has a high long-term recurrence rate, this disadvantage is outweighed by the low incidence severe postvagotomy symptoms.     

The surgical treatment of bile reflux gastritis: a study of 59 patients.

Fifty-nine patients underwent duodenogastric diversion for bile reflux gastritis. Sixty per cent of 37 patients who underwent measurement of solid food gastric emptying had delayed gastric emptying. Patients were also assessed in terms of the degree of gastritis present endoscopically. Fifty-six patients were available for follow-up of from six months up to six years. The results demonstrated the following: Patients with delayed gastric emptying and reflux gastritis fared poorly after duodenogastric diversion; the greater the severity of gastritis visible by endoscopy, the better the results of diversion. Only 47% of patients achieved a satisfactory result of duodenogastric diversion.     

Surgery for recurrent peptic ulceration.

Sixty-six patients having surgery for recurrent peptic ulcers over a 10-year period are reviewed. The majority of the patients were male and developed their initial ulcers at an early age. Bleeding was the most common presenting symptom. Seventy-one percent of the recurrences occurred within three years. Barium meal X-ray examination plus endoscopy gave the correct diagnosis in 96% of cases. The causes of the recurrent peptic ulcers were: (1) incomplete vagotomy; (2) inadequate gastric resection; (3) inappropriate surgery; (4) Zollinger-Ellison syndrome; (5) gastric outflow obstruction; and (6) bile reflux. Other factors such as alcohol, analgesic abuse and psychiatric disorders were found to be common associations. Resection plus vagotomy was the summation of primary and secondary surgery in 85%. The operative mortality was 3%. Eighty-five percent of patients had a Visick grading of I or II. Only one patient had a further recurrent ulcer and this healed on medical treatment.     

Clinical value of endoscopy and histology in the diagnosis of duodenogastric reflux disease.

BACKGROUND. The endoscopic observation of a bile lake in the stomach, antral gastritis, or ulcerations and the histologic finding of foveolar hyperplasia or chronic gastritis have been implicated as indicators of excessive duodenogastric reflux. The accuracy of these criteria was evaluated in 135 patients with nonspecific symptoms in the foregut suggestive of duodenogastric reflux and no evidence for alcohol- or drug-induced gastric mucosal injury. METHODS. The presence of excessive duodenogastric reflux was objectively determined by means of both gastric pH monitoring and cholescintigraphy with cholecystokinin stimulation. RESULTS. Endoscopy showed antral gastritis in 67 patients, gastric ulcers in 19, and a bile lake in the stomach in 39 (total of 135 patients). Of 90 patients who underwent biopsy, histologic findings showed foveolar hyperplasia in 26, chronic gastritis in 19, and active gastritis in 28 patients. The latter condition was associated with Helicobacter pylori in 20 patients. When gastric pH monitoring, cholescintigraphy, or both were used as "gold standard," the sensitivity, specificity, accuracy, and positive predictive value of endoscopic and histologic criteria to diagnose the presence of excessive duodenogastric reflux were poor except in the rare case of active gastritis but no Helicobacter pylori. CONCLUSIONS. The presence of duodenogastric reflux disease cannot be accurately diagnosed with endoscopic or histologic criteria. The diagnosis should be made with objective techniques, particularly when surgical therapy is considered.     

Gastric ulceration after Nissen fundoplication

Thirteen patients developed gastric ulcers between 6 months and 8.5 years after Nissen fundoplication. Eight patients presented with epigastric pain alone, 3 with bleeding alone and 2 with both pain and bleeding. Nine ulcers (69 per cent) were high on the lesser curve, close to the fundoplication and 7 of these patients had recurrent hernias. Anatomical distortion produced by fundoplication is probably the most important aetiological factor, though gastric distention, bile reflux gastritis and ischaemia may be contributory.

Management of long-term failure after colon interposition for benign disease

PURPOSE: To assess causes and treatment of late failures of colon interposition. METHODS: We reviewed the charts of 6 patients who underwent one or more revisions of a colonic interposition at a mean of 16 years after colon interposition (CI). RESULTS: Symptoms of problems with the CI were dysphagia (67%), regurgitation (67%), pneumonia (40%), and chest pain (33%). Findings that accounted for failure were colonic redundancy (67%), and gastrocolonic reflux (50%). Approach was resection of redundant colon or management of reflux. Four patients underwent segmental resection of the colon preserving blood supply. Three patients had gastric resection or diversion of bile and acid for management of reflux. Treatment was successful in all patients. CONCLUSION: Late failure of colon interposition is secondary to conduit redundancy and severe reflux. Resection of redundant colon will correct colonic redundancy. Gastric resection or diversion of bile and acid corrects gastrocolonic reflux.     

Clinical Outcome of Pylorus-preserving Gastrectomy in Gastric Cancer in Comparison with Conventional Distal Gastrectomy with Billroth I Anastomosis

BACKGROUND: Pylorus-preserving gastrectomy (PPG) was originally a treatment option in gastric ulcer surgery and is now being performed as a limited surgery in some early gastric cancer cases. This study was designed to evaluate the postoperative functional characteristics of PPG versus conventional distal gastrectomy with Billroth I anastomosis (BI). METHODS: Patients who underwent PPG (study group) between November 1999 and April 2003 were enrolled and BI patients (control group) were matched for number, gender, age, weight, height, stage, and follow-up period. We evaluated postprandial symptoms and nutritional status. Gastric emptying studies with a 99mTc gamma camera, follow-up endoscopies with random biopsies of remnant gastric mucosa to evaluate bile reflux gastritis, and ultrasonography to detect gallbladder stones were performed. Recurrence and survival also were investigated. RESULTS: Twenty-two PPG patients (study group) and 17 BI patients (control group) were enrolled. Overall modified Visick scores of postprandial symptoms were lower in PPG patients than in BI patients (0.9 +/- 0.7 vs. 2.3 +/- 1.4; p = 0.018). Gastric emptying was delayed in PPG patients versus BI patients for solids (p < 0.05). Moderate gastritis, bile reflux, and gallbladder stone were observed only in BI patients. Remnant stomach pathologic findings corresponding to bile reflux gastritis in the two groups were similar, except for Helicobacter pylori colonization. No recurrence occurred in either group (mean follow-up period = 41 +/- 9.5 months). CONCLUSIONS: PPG patients had fewer subjective postprandial symptoms than BI patients. The present study also suggests that PPG has advantages over BI in terms of the avoidance of bile reflux and gallbladder stones.     

Bilateral exclusion of the duodenum in reconstructive surgery of the stomach]

The article analyses the results of modified gastric resection after Roux with bilateral exclusion of the duodenum in 13 patients with disease of an operated stomach. The operations were performed for peptic ulcer of the gastroenteroanastomosis in 5 patients, for biliary reflux gastritis in 3, and for reflux gastritis and coexistent Stages II-III dumping syndrome in 5 patients. The outcomes of treatment were studied in follow-up periods of up to 3 years. The results were good in 10 patients, satisfactory in 2, and poor in 1 patient. Recurrent peptic ulcers were not encountered. The clinical picture of biliary reflux gastritis was completely relieved in all of the 8 patients. The dumping syndrome phenomena were arrested in 2 patients and relieved significantly in another 2.     

Primary Roux-Y gastrojejunostomy versus gastroduodenostomy after antrectomy and selective vagotomy

One hundred twenty-one patients with prepyloric ulcer disease entered a randomized clinical trial comparing gastroduodenostomy with Roux-Y gastrojejunostomy after antrectomy and selective gastric vagotomy. The postoperative course and morbidity were quite similar in the two study groups, as was the postoperative infectious complication rate. Forty-four of the patients with a Billroth I reconstruction and 52 of those with a Roux-Y reconstruction were followed up with a clinical assessment at least 6 months after the operation. The postgastrectomy symptoms were quite frequent, but did not differ between the two study groups. Seventy-five percent of the patients with a Billroth I gastroduodenostomy had symptoms corresponding to Visick grades 1 and 2, compared with 81% of those with Roux-Y reconstruction. Although the latter procedure was very effective in preventing bile reflux to the gastric remnant, no difference was observed in the gastric emptying rate after the two operations.     

Experimental and clinical results with proximal end-to-end duodenojejunostomy for pathologic duodenogastric reflux.

Existing Roux-en-Y bile diversion procedures for duodenogastric reflux coupled with distal gastric resection or antrectomy and vagotomy have varied success due to interruption of the physiologic relationships between stomach and duodenum, the reduction of the gastric reservoir, the side effects of vagotomy, and the effect of the Roux limb on gastric emptying. A new bile diversion procedure, suprapapillary Roux-en-Y duodenojejunostomy, was studied, which eliminates the need for gastric resection to prevent jejunal ulcers by preserving duodenal inhibition of gastric acid secretion and the protective effects of duodenal secretion on the surrounding mucosa. Experimentally, the incidence of jejunal ulceration was significantly decreased by the preservation of the proximal duodenum. Clinically, bile diversion by suprapapillary Roux-en-Y duodenojejunostomy alleviates symptoms of duodenogastric reflux disease without being ulcerogenic (in the presence of normal gastric secretion) or prolonging gastric emptying.     

Improvement in the immediate and late results of gastric resection in patients with gastroduodenal ulcers]

An analysis of treatment of 420 patients following distal (406) and proximal (14) resections of the stomach for gastroduodenal ulcers was made. No incompetence of the stump sutures of the duodenum, stomach and anastomoses was noted. The dumping syndrome was observed in 2.8%, reflux gastritis in 5.1% of the patients. Results of the surgical treatment of ulcer disease were improved by using original methods of distal resection of the stomach with the formation of an artificial constrictor of the gastric stump and a reflux esophagogastric anastomosis.     

Gastric mycosis following gastric resection and vagotomy.

In a prospective five-year follow-up study of 289 consecutive patients subjected to antrectomy and gastroduodenostomy with or without vagotomy, 130 patients underwent gastroscopy. Gastric mycosis was present almost exclusively in patients subjected to combined antrectomy and vagotomy (36%). Gastric acidity seemed to be of only minor or no importance in the development of the mycosis. The residual volume in the gastric remnant was significantly higher in patients with gastric mycosis. The impaired emptying of the gastric remnant is most likely a vagotomy effect and may be the main reason for the development of gastric mycosis. A simple but effective method was developed to evacuate gastric yeast cell aggregates. Gastric mycosis seems to give rise to only slight symptoms, mainly nausea and foul-smelling belching, whereas the reflux of duodenal contents that often occurred in combination with gastric mycosis was more likely to cause gastritis and substantial discomfort.     

Marginal ulcer following gastric bypass for morbid obesity

Four hundred twelve patients underwent gastric bypass for treatment of morbid obesity between 1981 and 1985 at the University of Florida Affiliated Hospitals. Thirty-four patients (8.2%) developed marginal ulcers, considerably higher than the 0-3 per cent ulcer occurrence commonly reported in the literature. Factors predisposing to ulcer formation include: (1) a large gastric pouch; (2) a vertically oriented pouch; and (3) staple-line dehiscence. Twenty-two of 34 patients (65%) with symptomatic marginal ulcers were noted to have staple-line disruption. Twenty-one of these patients (95%) eventually required operative therapy for their ulcers compared with four of 12 patients (33%) with an intact gastric staple line. Surgical therapy consisted of takedown of the Roux-en-Y limb with resection of the ulcer and gastrogastrostomy. Staple-line dehiscence is a significant etiologic factor in the development of marginal ulcer following gastric bypass and when present constitutes an indication for reoperation.     

Marginal resection for osteosarcoma with effective preoperative chemotherapy

Objective: To present the clinical results of marginal resection with effective preoperative chemotherapy for treatment of osteosarcoma. Methods: Thirty‐eight patients (20 male and 18 female, average age 17 years), underwent marginal resection after confirmation of effective preoperative chemotherapy between 1999 and 2008 and the results were analyzed retrospectively. The distal femur was involved in 22 cases, proximal tibia in 11, proximal humerus in 4, and proximal fibula in 1. Thirty‐seven patients were stage IIB and one IIIB. Twenty‐nine patients were treated with the DIA, and 9 with the MMIA protocol. Twenty‐one patients underwent tumor resection and bone allograft transplantation. The epiphysis was preserved in 9 patients, and not in the other 12. Eleven patients underwent tumor resection and prosthetic replacement, and 4 tumor resection with autograft implantation. One patient underwent tumor resection and allograft with preservation of the epiphysis; another underwent marginal tumor resection only. Results: All patients received effective preoperative chemotherapy. At a median follow‐up of 52 months, local recurrence had developed in one patient (2.6% local recurrence rate). Pulmonary metastases developed in 9 patients (23.7%). Five patients died of metastases, one died of intracranial hemorrhage due to thrombocytopenia caused by postoperative chemotherapy. The overall 2‐year survival rate was 87.3%, and event‐free survival rate 75.5%. The overall 5‐year survival rate was 74.7%, and event‐free survival rate 60.8%. Excellent to good function of affected limbs was achieved in 60.5%. Conclusions: With careful preoperative evaluation and effective preoperative chemotherapy marginal resection of osteosarcoma can produce good results. Marginal resection of osteosarcoma should be performed by an experienced surgeon who is familiar with the limb salvage rules for osteosarcoma.     

Primary bile reflux gastritis: diagnosis and surgical treatment

Bile reflux gastritis has been recognized since the first successful gastric operations and has persisted for more than a century. Diagnosis has been difficult and non-operative therapy largely ineffective. Early attempts at surgical correction resulted in stomal ulceration and it was not until the advent of flexible endoscopy and other techniques that diagnosis became more secure. Operative attempts at correction have included the Roux-en-Y procedure, the Braun enteroenterostomy, and Henley jejunal interposition. None of the procedures has been uniformly successful, and the Roux-en-Y has resulted in a disabling stasis syndrome in most patients. The diagnosis of bile reflux without previous gastric surgery has been even more elusive and seems to be associated with previous cholecystectomy. Thirty-one patients diagnosed with primary bile reflux, having typical symptoms of epigastric pain, nausea, and bilious vomiting have been treated by diverting bile flow through a Roux-en-Y choledochojejunostomy without accompanying gastric resection or vagotomy. There were no operative deaths and no long-term problems, such as anastomotic stricture. Two patients had self-limited bile leaks. Twenty-seven of the 31 patients (87%) have achieved complete relief of symptoms and have no gastrointestinal complaints. Serial gastric emptying has demonstrated no alteration in 9 of 12 patients who were normal before operation, and improvement in 12 of the 19 (63%) patients with abnormal preoperative studies.     

Complications associated with surgical treatment of congenital intrinsic duodenal obstruction

Although survival rates for infants undergoing surgical treatment for congenital intrinsic duodenal obstruction are high, long-term follow-up suggests a high complication rate related to surgical therapy. We reviewed 33 neonates who underwent surgery for congenital intrinsic duodenal obstruction during the past 10 years. There were 20 girls and 13 boys; the mean gestational age was 36 weeks, and mean birthweight was 2,485 g. Bilious vomiting and intestinal obstruction were the most frequent presenting symptoms. Hydramnios was present in 75% of cases and 21% had associated Down's syndrome. Findings at laparotomy included duodenal atresia (14), annular pancreas (11), and duodenal diaphragm (8). The most frequent surgical procedure was side-to-side duodenoduodenostomy (DD), followed by duodenojejunostomy and resection of web with Heineke-Mikulicz type duodenoplasty. Bowel transit was reestablished at a mean of 13.1 days (range, 6 to 45 days). Seventy-percent of patients developed postoperative complications, the most frequent being megaduodenum with blind loop syndrome or bile reflux gastritis (22%), cholestatic jaundice (17%), gastroesophageal reflux (17%), delayed transit (8%), and bowel obstruction (8%). Six patients (18%) required secondary surgical procedures for postoperative complications (ie, megaduodenum, nonfunctioning anastomosis, missed intrinsic stenosis). Two patients died (6%). Stagnation and functional obstruction in the proximal duodenum is the main factor influencing the morbidity rate among these patients. Consideration should be given to the tapering duodenoplasty and diamond-shaped anastomosis in order to help reduce problems associated with megaduodenum and help restore earlier bowel transit.     

The surgical treatment of chronic gastric atony following Roux-Y diversion for alkaline reflux gastritis.

Symptoms of severe nausea, vomiting, abdominal pain, and frequent bezoars, as well as objective gastric retention, can occur following Roux-Y biliary diversion for alkaline reflux gastritis. Medical therapy and prokinetic drugs have proven ineffective. This review evaluates 37 patients who underwent further gastric resection from 1979 to 1987 to improve gastric emptying and resolve symptoms. Fifteen patients underwent perioperative radionuclide solid-food gastric emptying studies. Seventy-three per cent (27 of 37 patients) of the patients who underwent further gastric resection (70% to 95%) had a satisfactory postoperative response. Twenty patients were graded Visick 1 or 2 and 7 Visick-3 patients, although much improved, still had some symptoms of gastroparesis. Twenty-seven per cent (10 of 37 patients) failed to improve and underwent completion total gastrectomy. Overall, 70% of this group had almost complete resolution of their symptoms. Three of 10 patients were considered "failures" due to postprandial pain in 1 and early vasomotor dumping in 2. Of the 10 patients who failed initial revisional surgery, 7 underwent a 70% to 80% subtotal gastric resection (STG) and 3 patients underwent 85% to 95% extensive resection (EXT.G.). Of the 15 patients who underwent perioperative radionuclide evaluation, a mean two-hour gastric retention of 61.4% +/- 4% (SEM) decreased to 25% +/- 4% following further gastric resection. Eight patients were in the STG group and seven patients were in the EXT.G group. Following STG, mean two-hour gastric retention of 58.2% +/- 3.5% decreased to 38% +/- 3% (p less than 0.05). In seven patients who underwent EXT.G, mean two-hour retention of 65% +/- 4% decreased to 10% +/- 2.5% (p less than 0.005). EXT.G resulted in normal gastric emptying and few late failures. In post-Roux-Y patients with symptoms of gastroparesis and documented gastric retention, EXT.G normalizes gastric emptying and restores a better quality of life. Total gastrectomy should be reserved for those patients who are failed by more extensive resection.
