Laparoscopic Heller's cardiomyotomy in achalasia. Is intraoperative endoscopy useful, and why?

BACKGROUND: Inappropriate length of the myotomy incision along the stomach, the most common technical fault during Heller's cardiomyotomy, is related to the difficulty of identifying the gastro-esophageal junction, in particular during laparoscopic surgery. The goal of this study was to evaluate the contribution of endoscopy to gastro-esophageal junction identification during laparoscopic Heller's cardiomyotomy. METHODS: In a group of 19 patients with intraoperative endoscopy with laparoscopic Heller's cardiomyotomy, surgical and endoscopic criteria for gastro-esophageal junction identification have been assessed. Then postoperative results of this group were compared with those of another group of 16 patients previously operated on without intraoperative endoscopy. RESULTS: Endoscopic and laparoscopic criteria for gastro-esophageal junction identification were discordant in 11 patients (11/19, 58%). The cardia was in all these cases at a more distal site with endoscopic criteria. Complications ascribable to suboptimal technique were more frequent in the group without intraoperative endoscopy (7/16 patients) than in the other group (2/19 patients). CONCLUSIONS: Endoscopy during laparoscopic Heller's cardiomyotomy is of great assistance in identifying the cardia, and thereby could improve surgical outcomes.

[Spontaneous gas gangrene of the pancreas caused by Clostridium perfringens].

The case of a 60-year-old patient with acute biliary pancreatitis spontaneously infected by Clostridium perfringens is reported. On CT scan, all the pancreatic bed was filled by gas. The patient survived. Four cases have previously been published. Three were fatal and 2 occurred after a pancreatic biopsy. Complete gas gangrene of the pancreas is a severity criterion and suggests an infection by Clostridium perfringens.

[Laparoscopy versus the Shouldice intervention in the treatment of unilateral inguinal hernia: can the operative surcosts be minimized?].

AIMS: Laparoscopy is more expensive than Shouldice procedure for inguinal hernia repair. The aims of this study were to evaluate the overcost, to look for its causes and to propose a strategy of cost reduction. METHODS: One hundred and sixty three unilateral inguinal hernia repairs were performed from January 1995 to June 1996 in our institution, functioning under financial rule of total endowment. Forty five of the 163 procedures were laparoscopic procedures. The mean operative cost of each procedure was calculated from physician, personnel and equipment costs (amortization, consumable products and maintenance). RESULTS: The mean costs were 2,210 FF and 6,779 FF for Shouldice and laparoscopic procedures, respectively. This overcost of 4,569 FF was reduced to 893 FF by increasing surgeon's experience, which shortened operative duration and ward cost, and by the use of a non specific mesh fastened in place with threads. The mean operative cost of laparoscopy was then 3,103 FF. CONCLUSION: A change in surgical practice allows a reduction in the operative overcost of laparoscopic unilateral inguinal hernia repair by 80.4%.

[Colonic polyps considered unresectable by endoscopy. Removal by combinations of laparoscopy and endoscopy in 65 patients].

OBJECTIVE: To determine to what extent segmental colectomy could be avoided in patients with polyps though to be endoscopically unresectable by using combination laparoscopy and endoscopy. METHODS: Sixty-five patients referred for colonic polyps though to be unresectably by conventional endoscopy were studied. After analysis of the endoscopic findings, endoscopy was performed in a medicosurgical unit when possible, otherwise a surgical procedure was performed consisting of laparoscopy followed by colonoscopy. Therapeutic strategy depended on laparoscopic and endoscopic findings. RESULTS: Segmental colectomy was avoided in 44 patients (67.7%). Among them, 20 were treated by simple endoscopic polyp removal, 12 by laparoscopy-assisted colonoscopic polypectomy, 9 by laparoscopic wedge colonic resection and 3 by colotomy after colonic exteriorization and polyp resection. Laparoscopic or laparoscopy-assisted segmental colectomy was performed in 16. Segmental colectomy by laparotomy was necessary in 5. No complication occurred. CONCLUSION: Segmental colectomy for unresectable colonic polyps could be avoided in more than half of the patients using laparoscopy and colonoscopy combinations.

[Inguinal hernia treatment].

Efficacy of groin hernia repair is mainly evaluated by its recurrence rate. In the literature it depends on the type of surgery but also on the follow-up, which must last 5 years at least and has to be more than 90% complete. To acertain the clinical result, the patient must be examined by a surgeon. Among herniorraphies techniques, Shouldice procedure has the lowest recurrence rate. The Lichtenstein operation leads to less recurrence rate than McVay's, for mixt (direct and indirect) hernias. Post operative pain might be diminished after the former procedure. No randomized control trial has compared raphies and techniques involving a prosthesis, in groin hernia repair. Among laparoscopic techniques, the transabdominal and preperitoneal approaches have less recurrence rate than the entirely intra peritoneal one, which has been abandonned. Their recurrence rate is not different than recurrence rate of herniorraphies and techniques using a prosthesis. With them, post operative abdominal pain is diminished. Nevertheless no randomized control trial has demonstrated any superiority of laparoscopic techniques on the Shouldice procedure.

Predicting common bile duct lithiasis: determination and prospective validation of a model predicting low risk.

BACKGROUND: The aim of this two-part prospective study was: (1) to identify simple, noninvasive, preoperative factors associated with low or very low risk of common bile duct lithiasis (CBDL); and (2) to test the validity of the statistical model obtained during Part One by the postcholecystectomy follow-up of patients classified into a low-risk group. PATIENTS AND METHODS: In Part One of the study, preoperative clinical, biologic, and ultrasonographic data, and intraoperative cholangiographic findings were collected from 503 consecutive patients undergoing cholecystectomy for symptomatic lithiasis from 1985 to 1989. Using the data obtained in Part One, a linear logistic model was used prospectively in Part Two to determine the prediction of absence of CBDL in 279 consecutive patients. No jaundice, normal transaminase levels, common bile duct (CBD) diameter < 8 mm, and no intrahepatic duct enlargement defined the low-risk group of CBDL. RESULTS: In Part One, CBDL was present in 84 (17%) of all patients. Five parameters were used to classify 73% of all patients as low risk of CBDL and 27% as high risk. In the low-risk groups, CBDL was present in 1% of 116 cases with acute gallbladder complications, and 5% of 250 cases with no acute gallbladder complications. In Part Two, 171 (61%) patients were classified in the low-risk group (Group 1), and CBD stones were not sought by any additional preoperative investigations or intraoperative cholangiography (IOC). One hundred eight patients (39%) were considered at risk of CBDL (Group 2). Mean follow-up was 20.6 months (median 19); 2 patients (1%) in the low-risk group presented a symptomatic retained stone. CONCLUSIONS: This study validated this simple model for predicting risk of CBDL and avoiding invasive preoperative investigations--as well as IOC--in more than 60% of symptomatic cholelithiases. In addition, this model seemed useful for defining patients in whom further exploration for CBDL was justified, since 42 (39%) of the 108 Group 2 patients were proved to have CBDL.

[One hundred and twenty-five consecutive choledochotomies for suspected lithiasis without mortality. Current state of complications from common bile duct surgery].

The postoperative courses of 125 consecutive surgical common bile duct explorations performed between 1983 and 1990 were analysed. All cases of common bile duct lithiasis, but three, were operated on. Intraoperative cholangiography was performed in 98 percent and cholangioscopy in 92 percent of patients; common bile duct stones were found in 95 patients (76 percent); the common bile duct was sutured without drainage in 78 patients (58 percent). There were no deaths. Morbidity was 14 percent, of which 10 percent were serious. Four percent of common bile ducts retained stones. The specific morbidity was 4 percent. These results confirm the reliability of surgical management of common bile duct stones and therefore should be considered for the evaluation of new procedures, such as laparoscopic treatment of common duct stones, or combined laparoscopic cholecystectomy and endoscopic sphincterotomy.

Total duodenal diversion in patients with previous gastric surgery.

Total duodenal diversion (TDD) was performed in 19 patients with severe post-gastric surgery symptoms. Previous operations were truncal vagotomy associated with pyloroplasty or antrectomy (n = 6), proximal esophagogastrectomy (n = 8) or total gastrectomy (n = 5). Technical adjustments to the standard procedure (truncal vagotomy, antrectomy and gastrojejunal anastomosis using a 70 cm Roux-en-Y loop) were required. There were no postoperative deaths, no anastomotic leakage or anastomotic ulceration. The main symptoms were eliminated, and endoscopic gastritis and esophagitis healed in all patients. Heartburn and bilious vomiting ceased in all patients, but in five out of 14 patients with a residual stomach some symptoms persisted. TDD proved a safe and effective treatment of disabling symptoms following gastric surgery.

[Complications of peroperative sterilization of hydatid cysts of the liver. Apropos of 6 cases].

Injection of scolicidal solution into the hydatid cysts has been used to sterilize the cyst and to prevent intra-abdominal dissemination of the parasite during surgery. We report six cases of complications of this measure. Intraoperative collapse in one patient and an immediate postoperative death occurring after injection of 10% H202. Postoperative sclerosing cholangitis occurred in 4 patients in whom 2% formalin or 20% sodium chloride was injected into the cyst. Cholangiography showed strictures affecting the intrahepatic biliary tree in 2 and both the intra and extra biliary tree in 3. Sclerosing cholangitis in these patients was likely to result from the caustic effect of the scolicidal solution having diffused from the cyst into the biliary tree. Jaundice developed in 3 patients from 2 to 5 months after operation. The intra-operative collapses is related to the injection of H202 into the cyst. The dramatic increasing of the volume of the cyst may fissure of the cyst-wall and allows the passage of gaz into the circulation. As the efficacity of intracystic injection of a scolicidal solution in preventing the dissemination of the parasite is still unproven, we recommend the rejection of this maneuver in the surgical treatment of hydatid disease of the liver.

[Intravenous cholangiography is not indicated before cholecystectomy for uncomplicated lithiasis].

The purpose of this prospective study was to assess the usefulness of intravenous cholangiograms before elective cholecystectomy for lithiasis. The accuracy of preoperative intravenous cholangiography to detect choledocolithiasis was compared with that of routine operative cholangiography. All patients had preoperative intravenous cholangiography provided that they did not have known common bile duct gallstones or a previous history of adverse reaction to iodine. As well, patients presenting with cholestasis, cholecystitis or cholangitis were excluded. A choledocotomy was performed when the operative cholangiography disclosed choledocolithiasis; the preoperative intravenous cholangiograms were shown to the surgeon only after the operation. One hundred patients were selected among 206 consecutive operations for biliary lithiasis. A choledocolithiasis was detected in 3 preoperative and in 9 operative cholangiographies. Twelve choledocotomies were performed: one or more stones (1 to 12) were found in 9 patients; operative cholangiography was accurate in all these cases whereas preoperative cholangiography was accurate in only 2 (sensitivity = 22 percent). We conclude that preoperative cholangiography is useless before elective cholecystectomy for lithiasis and is unreliable to select patients in which operative cholangiography could be omitted.

[Treatment of complicated peptic esophagitis. Role of total duodenal diversion].

Total duodenal diversion was performed in 60 patients with reflux oesophagitis complicated by stricture, brachyoesophagus, endobrachyoesophagus or previous oesophago-gastric surgery. The standard operation (truncal vagotomy, antrectomy, 70 cm Roux-en Y anastomosis) was carried out in 41 patients; technical adjustments were necessary in 19 patients previously operated. One patient died of post-operative pulmonary embolism. Lasting cure of the oesophagitis was obtained within less than 3 months in 56/59 patients (93 per cent). Three-hour post-prandial pH measurements showed control of the reflux in 48/52 patients (92 p. 100). Anastomotic ulcers developed in 3 patients who did not have vagotomy. One case of complete remission of endobrachyoesophagus was observed, and 4 cases are now in partial remission. Digestive tract sequelae were found in 9 patients who had undergone surgery, but they were disabling in only one of these. These results suggest that total duodenal diversion is a suitable treatment of complicated reflux oesophagitis.

Total duodenal diversion in the treatment of complicated peptic oesophagitis.

Total duodenal diversion (TDD) has been carried out in 59 patients with complicated forms of peptic oesophagitis (acquired short oesophagus, columnar lined oesophagus, previous oesophagogastric surgery, stenosis). A standard procedure (truncal vagotomy, antrectomy and gastrojejunal anatomosis using a 70 cm Roux-en-Y loop) was performed in 41 patients, and some technical adjustments were required in 18 patients previously operated on. One patient died from postoperative pulmonary embolism. Bowel movements were resumed before the fifth postoperative day in 93 per cent of patients (54/59). Early postoperative complications (gastroparesis, 5; fistula, 1; subsequent operation, 1) occurred in 12 per cent of patients. Stabilization of the oesophagitis was achieved in less than 3 months in 95 per cent of cases (55/58). There were two cases of regression of columnar lined oesophagus. A 3-h postprandial pH assessment showed that the reflux had been controlled in 92 per cent of cases (47/51). One patient who still had an acid reflux died subsequently of a perforated oesophageal ulcer. Three anastomotic ulcers occurred in eight patients who did not have vagotomy. Digestive side-effects have been observed in nine patients, but only in one case were they crippling. Our results suggest that TDD is a suitable form of treatment for complicated forms of peptic oesophagitis.

Functional and oncologic results after coloanal anastomosis for low rectal carcinoma.

Thirty-five patients who had adenocarcinoma of the middle third of the rectum were treated by resection and coloanal anastomosis. The aim of this study was to assess functional and oncologic results of an original technique of coloanal anastomosis. There was no operative mortality, and operative morbidity consisted of seven anastomotic leaks with two failures. Among 31 patients assessed for functional results only one had unsatisfactory results. Good continence was obtained within a few weeks for the 30 patients who had satisfactory results. No patients were lost to follow-up, which was over 5 years in 24 patients (68%). The 5-year survival rate was 64%, identical to that for other series.
