Laparoscopic treatment of pancreatic pseudocysts.

BACKGROUND: A multicentric study was performed to evaluate the clinical results after laparoscopic treatment of pancreatic pseudocysts (PP). METHODS: We collected the data of 17 patients presenting with PP and operated on by laparoscopy between 1996 and 2001. There were nine men and eight women with a median age of 42 years (range 30-72). In 15 patients the PP developed after acute pancreatitis and the median delay between the acute onset and surgery was 7 months (range: 2-24). In two patients the PP was associated with chronic pancreatitis. All the patients had a single PP with a median diameter of 9 cm (range: 5-20). RESULTS: According to the location of the PP, a cystogastrostomy was performed in 10 patients and a cystojejunostomy in seven patients. The median operative time was 100 min (range: 80-300). Laparoscopic PP surgery was completed successfully in 16 patients and the median size of the cystoenterostomy was 3 cm (range: 2-5). Necrotic debris was present within the PP in 11 patients. The median postoperative hospital stay was 6 days (range: 4-24). No mortality and no immediate morbidity were recorded. However, two patients were readmitted within the first 3 postoperative weeks because of secondary PP infection. The first patient had an early closure of cystogastrostomy and was treated by endoscopic placement of a stent. The second represented with a right retrocolic abscess after cystojejunostomy and was treated by percutaneous drainage. One patient was lost for follow-up 2 months after surgery. The others had regular clinical and radiological controls. With a median follow-up of 12 months (range: 6-36), no recurrence of PP was observed. CONCLUSIONS: The laparoscopic treatment of PP was associated with a low postoperative complication rate and an effective permanent result. That approach avoided some difficulties, particularly bleeding that is classically linked with endoscopic internal drainage.

Achalasia: the case for primary laparoscopic treatment.

Laparoscopic Heller myotomy offers the best-known surgical therapy for esophageal achalasia. Nevertheless, this procedure continues to compete with alternative endoscopic treatment and is often considered only as a secondary resort. In this study, the authors performed a review of the results of laparoscopic Heller myotomy and an evaluation of the impact of previous endoscopic treatment regarding perioperative complications and late results. Twenty-seven patients with achalasia confirmed by a manometry examination underwent a primary laparoscopic Heller myotomy (group 1, n = 14) or experienced endoscopic treatment failure (group 2, n = 13). A dysphagia score (0-4) was obtained before and after surgery. Clinical course was reviewed at 2 months and then every 6 months after surgery. In December 1999, patients answered a questionnaire regarding surgery satisfaction, postoperative reflux, and dysphagia for statistical analysis. There were no deaths. Mean hospital stay was 5.6 days. Three perforations occurred in group 2 (25%) versus one in group 1 (6%) (not statistically significant). At a mean 27-month follow-up, the dysphagia score was significantly (P < 0.001) improved in both groups but more significantly in group 1 versus group 2 (not statistically significant). Only one patient in group 2 reported heartburn. All patients in group 1 (100%) were satisfied with surgery as opposed to 10 of 13 patients (75%) in group 2 (P < 0.10). Primary laparoscopic Heller myotomy appears to be the treatment of choice for achalasia. Previous endoscopic treatment increases intraoperative complications and may affect long-term results.

Laparoscopic-assisted colectomy for diverticular sigmoiditis. A single-surgeon prospective study of 65 patients.

BACKGROUND: The feasibility of laparoscopic colectomy has now been established, but little attention has been paid to its indications. Therefore, we undertook a prospective study of the laparoscopic treatment of diverticular disease of the colon. METHODS: A total of 65 patients were operated on by a single surgeon between July 1993 and March 1998. Indications for operation included a previous acute attack of diverticulitis, abscess, or colovesical fistula. All procedures were laparoscopic-assisted. RESULTS: Three conversions (4. 6%) were necessary. There were no postoperative mortalities. Nine postoperative complications occurred (17%); one of them (1.5%) was directly related to the operation and required reoperation. Patients passed flatus after 2.2 +/- 1.2 days (range, 1-9), and oral feeding was started after 2.6 +/- 1.3 days (range, 1-9). The hospital stay was 7.6 +/- 3 days (range, 5-19). No patient with >6 months of follow-up (40 patients) had any complaints related to diverticular disease. CONCLUSIONS: These results suggest that this procedure is as safe as the traditional approach and provides superior comfort and cosmesis with the same long-term outcome.

Carcinoma of the ampulla of Vater: prognostic factors after curative surgery: a series of 45 cases.

BACKGROUND: Some adjuvant or neoadjuvant therapy could be important for patients operated on for tumours of the ampulla of Vater, especially for those having a higher risk of recurrence. AIM: To evaluate prognostic factors after curative surgery based on a series of 45 cases of malignant tumours of the Oddi sphincter. PATIENTS: From 1970 to 1992, a curative resection was performed in 45 patients (age 62.8 (SD 10.1) years) with adenocarcinoma of the ampulla. Surgical procedures included pancreatoduodenectomy (n = 42) and resection of the ampulla (n = 3). Actuarial survival was 44 (SD 9)% at five years. METHODS: Various prognostic variables were studied: clinical manifestations, macroscopic aspect, differentiation, noninvasive adenomatous component, mucin histochemistry, immunohistochemistry (CEA, CA19.9, p53, Ki67), and accepted classifications (Blumgart and Kennedy, Martin, Yamaguchi and Enjoji, Talbot et al, pTNM). RESULTS: Variables with prognostic power, in order of importance were: Classification of Talbot et al; CA19.9; pTNM; sialomucins; classification of Yamaguchi and Ejoji; Martin classification; sulphomucins; non-invasive adenomatous component (positive > negative); jaundice; tumour localisation. CONCLUSIONS: This series confirmed the prognostic power of former classifications and showed the prognostic power of other variables (mucin, non-invasive adenomatous component, CA19.9).

Primary anastomosis with transverse colostomy as an alternative to Hartmann's procedure.

Hartmann's procedure remains the favoured option in patients with acute left colonic and sigmoid disease, despite the well documented morbidity and mortality associated with reversal. In 40 patients with left colonic pathology, primary anastomosis was performed; 32 had a covering transverse colostomy. There were six hospital deaths, five in the transverse colostomy group. Closure was not attempted in seven of the 27 patients surviving with a colostomy (three refused, four had disseminated malignancy). In the 20 undergoing closure, there was no morbidity or mortality. With advances in intensive care, antibiotic therapy and anaesthesia, it is reasonable to consider alternatives to Hartmann's procedure, particularly when subsequent reconstruction is envisaged.

Gastrointestinal surgical emergencies following kidney transplantation.

This study reports major gastrointestinal complications in a group of 416 patients following kidney transplantation. Three hundred and ninety-nine patients received a cadaveric kidney while the other 17 received a living related organ. The immunosuppressive regimen changed somewhat during the course of the study but included azathioprine, prednisolone, antilymphocyte globulin, and cyclosporin. Perforations occurred in the colon (n = 6), small bowel (n = 4), duodenum (n = 2), stomach (n = 1), and esophagus (n = 1). There were five cases of acute pancreatitis, four of upper gastrointestinal and two of lower intestinal hemorrhage, two of acute appendicitis, one of acute cholecystitis, one postoperative mesenteric infarction, and two small bowel obstructions. Fifty percent of the complications occurred while patients were being given high-dose immunosuppression to manage either the early postoperative period or episodes of acute rejection. Ten percent of the complications had an iatrogenic cause. Of the 31 patients affected, 10 (30%) died as a direct result of their gastrointestinal complication. This high mortality appears to be related to the effects of the immunosuppression and the associated response to sepsis. Reduction of these complications can be achieved by improved surgical management, preventive measures, prompt diagnosis, and a reduced immunosuppressive protocol.

[Treatment of pancreatic pseudocysts by laparoscopic cystogastrostomy].

AIM: To evaluate the clinical results of laparoscopic cystogastrostomy and to determine the potential advantages of this new therapeutic option. PATIENTS AND METHODS: This study concerned 12 patients presenting with pancreatic pseudocyst and operated on by laparoscopic cystogastrostomy between 1997 and 2002. There were five men and seven women with a median age of 46 years (range: 30-72). In ten patients, the pseudocyst developed after acute pancreatitis and the median delay between the acute onset and surgery was 7 months (range: 2-24). In two patients, the pseudocyst was associated with chronic pancreatitis. All the patients had a single cyst bulging into the posterior wall of the stomach and the median cyst diameter was 9 cm (range: 5-14). RESULTS: Endoluminal gastric laparoscopy was used in six patients and intraperitoneal transgastric laparoscopy in six patients. Conversion to open surgery was required in one patient because the cyst could not be correctly localised by laparoscopy. The median size of the cystogastrostomy was 3 cm (range: 2-5). In eight patients, necrotic debris were still present within the cyst. The median operative time was 90 min (range: 60-140) and the median postoperative hospital stay was 6 days (range: 4-24). No mortality was recorded and postoperative morbidity was limited to one haematoma of the rectus sheath on a port site. One patient was readmitted on the 20th postoperative day because of cyst infection due to partial closure of the cystogastrostomy and was treated by endoscopic placement of a stent. One patient was lost for follow-up 2 months after surgery. With a median clinical and radiological follow-up of 12 months (range: 6-36), no recurrence of pancreatic pseudocyst was observed. CONCLUSIONS: In this series, laparoscopic cystogastrostomy is associated with a low postoperative morbidity and an effective permanent result. Laparoscopy has two main advantages: an excellent control of haemostasis and the creation of a wide communication with debridement of the cyst contents thus minimizing the risk of infection or recurrence of the pseudocyst.

Focal nodular hyperplasia of the liver. A retrospective review of 20 patients managed surgically.

Focal nodular hyperplasia remains a difficult diagnostic and clinical dilemma. Over a 10-year period, 20 patients with this diagnosis underwent surgery in our service. Eight of the patients had focal nodular hyperplasia discovered incidentally as part of investigation or surgery for other unrelated conditions. Seventeen of the patients were female, with 64% receiving oral contraceptives. In the 12 patients without concomitant disease all but one had upper abdominal pain. Despite the use of CT scan, isotope studies, NMR, angiography, ultrasound and biopsy, a firm preoperative diagnosis of focal nodular hyperplasia was made in only one patient. Resective surgery was performed without complication in all cases. During a mean follow-up of 42 months (range 6-128 months) one patient died from lymphoma and two patients had recurrent abdominal pain. This study highlights the difficulty in preoperative diagnosis of focal nodular hyperplasia. Conservative treatment can be considered or resective surgery safely performed for symptomatic or suspect lesions.
