RESUMO

BACKGROUND/AIMS: This study aims to evaluate the outcomes of percutaneous cholecystostomy for acute calculous cholecystitis in patients with high surgical risk and determine whether subsequent cholecystectomy is beneficial and necessary. Percutaneous cholecystostomy has been shown to be a safe treatment option for patients suffering from acute cholecystitis but at high risk for emergency surgery. Controversies still exist on the approach of the cholecystostomy and the subsequent management of these patients. METHODOLOGY: From January 1996 to March 2004, percutaneous cholecystostomy was performed on 65 patients that suffered from acute calculous cholecystostomy but were considered high risk for emergency surgery (American Society of Anesthesiologists grade III or IV). Their clinical outcomes were described and risk factors for in-hospital mortality and recurrence of cholecystitis were identified by univariate and multivariate analysis. RESULTS: Percutaneous cholecystostomy was successfully performed in all patients (100%). The clinical response rate was 91%. The in-hospital mortality was 12.3%. Shock on admission was found to be a single independent risk factor for in-hospital death (p=0.006; odd ratio = 16.5; 95% CI = 2.2-123.1). Twenty-four patients underwent subsequent cholecystectomy whereas 33 did not. The 1-year and 3-year recurrence of acute cholecystitis were 35% and 46% respectively in patients who did not have subsequent cholecystectomy. Stone size > or = 1cm was independently associated with higher recurrence of acute cholecystitis (p=0.01; hazard ratio = 6.3, 95% CI 1.6-25.5). However, there was no difference in 1-year and 3-year overall survival between patients with or without cholecystectomy (82% Vs 81% and 59% Vs 63%, p=0.79). CONCLUSIONS: Percutaneous cholecystostomy is a safe and promising treatment for acute calculous cholecystitis in patients who are at high risk for emergency surgery. Cholecystectomy after the resolution of cholecystitis and optimization of associated medical illnesses is always advisable in order to prevent recurrent cholecystitis. However, the limited survival of these patients because of their old age and medical co-morbidities should be taken into consideration.

RESUMO

Primary small cell carcinoma of the esophagus (SmCC) is an uncommon aggressive tumor characterized by early systemic dissemination and poor prognosis, regardless of the methods of treatment. The optimal treatment strategy remains uncertain. A retrospective study was conducted to review the results of non-operative treatment for patients with limited and metastatic esophageal SmCC. Between 1993 and 2003, 10 patients were diagnosed to have primary esophageal SmCC in our institution. Six of them had disseminated diseases, whereas the other four had limited disease upon diagnosis. All patients were managed non-operatively by either chemotherapy and/or radiotherapy. The overall median survival was 8 months (range, 2-62 months). The survival was 4-62 months for patients with limited disease, whereas it was 2-10 months for patients with disseminated disease at initial diagnosis. In summary, the current study demonstrated satisfactory palliation could be achieved with chemo-radiation for patients with limited disease; however, the ultimate role of primary chemo-radiation for esophageal SmCC must await results from randomized trials.

RESUMO

BACKGROUND/AIMS: To review the results of laparoscopic biliary bypass for both benign and malignant pathologies in a minimal access surgery training center. METHODOLOGY: Retrospective review of a prospectively maintained database of laparoscopic biliary bypass during the period 1995-2004. RESULTS: During the review period 1995-2004, there were 26 laparoscopic biliary bypasses performed in our center which included 23 laparoscopic choledochoduodenostomy (LCD), 2 laparoscopic roux-en-Y choledochojejunostomy (LCJ) and 1 laparoscopic cholecystojejunostomy (LCCJ). Of the 23 LCD, all except 1 patient were operated for recurrent pyogenic cholangitis (RPC). The 2 LCJ and 1 LCCJ were performed for patients with advanced carcinoma in the periampullary region and simultaneous laparoscopic gastrojejunostomy (LGJ) was also performed to relieve the gastric outflow obstruction. Among the 23 LCD, there were 2 open conversions (7.7%) for lost broken tip of ultrasonic dissector and significant bleeding during choledochotomy respectively. Major complications occurred in 6 patients (23%), which included 3 bile leaks (11.5%), 1 intraabdominal collection (3.8%). 1 wound infection (3.8%) and 1 gastric stasis (3.8%). The only mortality in our series was a patient with carcinoma of head of pancreas undergoing simultaneous roux-en-Y LCCJ and LGJ. He had persistent gastric stasis after operation and required revision surgery for the kinked cholecystojejunostomy anastomosis. He finally died of myocardial ischemia after the second operation. As for the postoperative pain control, the mean pethidine consumption was 243.4 +/- 254.7 mg (range 0-1200 mg) and mean dologesic usage was 16.2 +/- 20.4 tablets (range 0-94 tablets). The average postoperative hospital stay was 12.6 +/- 11.5 days (range 5-60 days). The long-term functional results were satisfactory and only 1 patient had recurrent stone upon a mean follow-up of 32.3 months. Among the patients with malignant biliary obstruction, the only mishap was as previously mentioned and the remaining 2 patients could enjoy satisfactory palliation for more than a year before death. CONCLUSIONS: Laparoscopic bypass is not only feasible but also highly effective in relieving biliary obstruction with good postoperative results in both benign and malignant conditions.

RESUMO

BACKGROUND: A newly constructed Endoscopic-Laparoscopic operating room (Endo-Lap OR) started to operate in our department in January 2005. A prospective study was conducted to evaluate its feasibility, efficacy, and safety, as well as the staff's satisfaction. PATIENTS AND METHODS: From January 2005 to September 2005, all patients undergoing operation in this Endo-Lap OR were included in the study. The patient's diagnosis, types of operating procedures, incidents of operating failure (either due to the hardware or the software of Endo-Lap OR) that led to a delay in the patient's transfer or that extended the total operating time were recorded. In addition, questionnaires regarding staff satisfaction with the new operating room were distributed to nurses, anesthetists, and surgeons. RESULTS: A total of 640 cases were included in the study period, 245 cases of open surgery, 282 cases of laparoscopic surgery, 82 cases of endoscopic surgery, 17 cases of video-assisted thoracoscopic surgery, and 14 cases of combined endoscopic-laparoscopic surgery. There were no reported incidents of operating failure related to hardware or software problems. The overall staff satisfaction was excellent. CONCLUSIONS: The integration of endoscopic and laparoscopic surgery into this newly constructed Endo-Lap OR is feasible and safe. The running of the operating room was smooth and it received a high level of acceptance and satisfaction from different staff members.

RESUMO

OBJECTIVES: To evaluate the role of laparoscopic exploration of the common bile duct in the management of common bile duct stones. DESIGN: Retrospective study. SETTING: Regional minimal access surgery training centre in Hong Kong. PATIENTS: Patients undergoing laparoscopic exploration of the common bile duct from 1995 to 2005. MAIN OUTCOME MEASURES: Demographic information, reasons for failed endoscopic retrograde cholangiopancreatography and open conversions, and operative morbidity and mortality. RESULTS: A total of 174 laparoscopic explorations of the common bile duct were performed. Indications for surgery (some overlapping) included: concomitant gallstones and common bile duct stones (n=68, 39%) in young persons (<60 years), previously failed endoscopic extraction (n=59, 34%), large (>2 cm) or multiple common bile duct stones (n=40, 23%), and need for laparoscopic bypass to improve bile drainage (n=34, 20%). Mean patient age was 63 (standard deviation, 16) years and 103 were female. Altogether 156 choledochotomies and 18 transcystic duct explorations were performed, with 12 (7%) open conversions. The mean operating time was 129 (standard deviation, 57) minutes. Additional procedures included: 54 laparoscopic operative cholangiographies, 34 laparoscopic biliary bypasses, and 31 instances of adhesiolysis in patients with a history of open upper gastro-intestinal surgery. Complete stone clearance was achieved in 160 (92%) patients. Non-lethal complications occurred in 34 (20%) patients and one died of sepsis after a major bile leak. The mean postoperative stay was 9 (standard deviation, 9) days. Stone recurrence ensued in seven (4%) patients after a mean follow-up of 37 (standard deviation, 29) months. CONCLUSIONS: Laparoscopic exploration of the common bile duct is highly successful and can achieve satisfactory ductal clearance even after unsuccessful endoscopic extraction and previous upper gastro-intestinal surgery. In skilled hands, for selected patients laparoscopic bypass can also achieve improved bile drainage.

RESUMO

BACKGROUND: Conventional preoperative staging for esophageal carcinoma could be inaccurate. Laparoscopy has been applied for the staging of various upper gastrointestinal malignancies. It can identify peritoneal and liver deposits not shown by imaging, and could reduce the number of nontherapeutic laparotomies. This study aimed to evaluate the efficacy of laparoscopic staging for the management of squamous cell carcinoma involving the mid and distal esophagus. METHODS: A retrospective review was performed for all patients with esophageal cancer evaluated for surgical resection from January 1998 to January 2004. Laparoscopy was performed for all the patients with mid and distal esophageal cancer immediately before open gastric mobilization. The efficacy of laparoscopy for the management of squamous cell carcinoma of the esophagus was evaluated. RESULTS: Among the 63 patients with potentially resectable disease shown on conventional imaging, 54 (84%) underwent esophagectomy with curative intent after laparoscopic staging. Seven patients (11%) underwent laparoscopy alone because of abdominal metastases (n = 5) or other medical conditions (n = 2) that precluded esophagectomy. Two patients (3%) had exploratory right thoracotomy without esophagectomy despite normal laparoscopic findings. The sensitivity and specificity of laparoscopic staging were 100% in this series of patients (100% sensitivity and specificity means no false-positives or -negatives). CONCLUSION: Laparoscopic staging is valuable for the management of patients with mid and distal squamous cell carcinoma of the esophagus. Patients with metastatic disease and those with prohibitive surgical risk can thus avoid unnecessary laparotomy and be offered other treatment methods.

RESUMO

BACKGROUND: Acute torsion of the greater omentum is a rare cause of acute abdomen in adults. We report our experience on the clinical presentation, diagnosis, treatment, and outcome of this condition. METHOD: This is a retrospective review of 9 patients who had a clinicopathologic diagnosis of acute torsion of the greater omentum and were treated at the Department of Surgery, Pamela Youde Nethersole Eastern Hospital from January 1994 to March 2004. Eight patients were male and 1 was female with a median age of 43 years (range, 24 to 65). Median body mass index was 24 kg/m(2) (range, 22 to 24). All presented with acute abdominal pain with a median temperature of 36.8 degrees C (range, 36.5 to 37.2) and a median white cell count of 9.5 x 10(9)/L (range, 7.4 to 15.1 x 10(9)). Preoperative ultrasound was done in 5 patients. RESULTS: All diagnoses were made during surgery. Resection of the infarcted omentum was performed for all patients (5 laparoscopic resections and 4 open resections). No postoperative complications occurred. The overall median time from admission to operation was 23 hours (range, 2 to 98). The overall median operating time and postoperative stay were 70 minutes (range, 38 to 105) and 3 days (range, 1 to 6), respectively. The median oral and parenteral analgesic requirement for postoperative pain control was less and the median hospital stay was shorter in patients who underwent laparoscopic resection. CONCLUSION: Acute torsion of the greater omentum is an uncommon cause of acute abdomen in adults, and preoperative diagnosis is usually difficult. Laparoscopy seems a safe and minimally invasive technique for both diagnosis and treatment of this rare disease entity.

RESUMO

BACKGROUND: Recurrent pyogenic cholangitis (RPC) is a common disease in Southeast Asia. Its classical presentation is repeated attacks of cholangitis with multiple recurrences of bile duct stones. The stones are commonly located in the left lateral segments (2 and 3) and therefore complete clearance is difficult to achieve by either endoscopic retrograde cholangiopancreatography or surgical exploration of the common bile duct. The definitive treatment usually involves resection of the stone-harboring segments. The recent advent in laparoscopic surgery has shown that hand-assisted laparoscopic segmentectomy is a safe and feasible, alternative. This study aimed to compare hand-assisted laparoscopic segmentectomy with open segmentectomy in patients with recurrent, RPC. METHODS: This study retrospectively reviewed a prospectively maintained database of both open and laparoscopic treatments for RPC in a single center between 1994 and 2004. During this period, patients with RPC and left intrahepatic (segments 2 and 3) ductal stones not amendable to endoscopic treatment were recruited for analysis. Patients with concomitant gallbladder stones and common bile duct stones were offered left lateral segmentectomy with cholecystectomy and exploration of the common bile duct. Selected patients would have choledochoduodenostomy drainage during the same operation. The operations were performed via either the hand-assisted laparoscopic approach or the open approach using an ultrasonic surgical aspirator. The two cohorts were compared with respect to perioperative parameters to determine whether there would be any advantage in attempting hand-assisted laparoscopic segmentectomy. RESULTS: During the study period from 1994 to 2004, 17 patients underwent left lateral segmentectomy for RPC. Of the 17 patients, 10 had hand-assisted laparoscopic resections, and 7 underwent open resections. All open resections were performed before 1999. Despite the small number of patients and potential type 2 error, there were no differences in age, sex distribution, number of cholangitic attacks, sessions of endoscopic retrograde cholangiopancreatography before surgery, or number of previous operation between the two groups. The median operating time was shorter in the open group (232.5 vs 150 min; p = 0.007), whereas the median blood loss was similar (350 vs 400 ml; p = 0.551). The median postoperative stay was 8 days for hand-assisted laparoscopic group versus 14 days for the open group. This difference was statistically significant (p = 0.019). There was one open conversion in the hand-assisted laparoscopic group because of intraoperative bleeding from the left hepatic vein. Postoperative complication rates were lower in hand-assisted laparoscopic group, but the difference was not statistically significant (20% vs 57%; p = 126). The intramuscular pethidine requirement again was less in hand-assisted laparoscopic group (0 vs 600 mg; p = 0.002). There was no operative mortality in either group of patients. No recurrent cholangitis was noted in either groups during the median follow-up period of more than 3 years. CONCLUSION: This study not only confirmed the feasibility of hand-assisted laparoscopic segmentectomy for recurrent pyogenic cholangitis, but also showed that this treatment approach is associated with less pain and shorter hospital stay. However, hand-assisted laparoscopic segmentectomy is a lengthier operation and technically more challenging. Nevertheless, the authors believe that with more experience and further improvement of ancillary technology, this procedure can become a standard treatment for recurrent pyogenic cholangitis in selected cases.

RESUMO

BACKGROUND/AIMS: Only a minority of patients with tumor at the pancreaticoduodenal junction is suitable for resection, palliation is however often required relieving the obstructive jaundice and gastric outflow obstruction (GOO). This study evaluates endo-laparoscopic approach as a palliative treatment of obstructive jaundice and malignant gastric outflow obstruction. METHODOLOGY: A retrospective review of a prospectively maintained database. During the period from 1992-2002, patients with diagnosis of unresectable tumor at the pancreaticoduodenal junction were evaluated. If the tumor was confirmed to be unresectable, patients would be offered either open double bypass or laparoscopic gastrojejunostomy (LGJ) +/- endoscopic or percutaneous transhepatic stenting for any obstructive jaundice, the choice of approach would depend on whether the endoscopic access was still maintained. RESULTS: Out of 942 patients with tumors around the pancreaticoduodenal junction during the study period from 1992-2002, there were 34 patients (13 male & 21 female) with median age 69 years (range, 48-87) selected for LGJ. Of these 34 patients, 3 of them underwent endoscopic biliary stenting whereas 16 jaundice patients were palliated by transhepatic biliary drainage. When the results were compared to the 35 open double bypass (roux-en-Y choledochojejunostomy and gastrojejunostomy) during the same study period, the median operation time was significantly shorter (80 vs. 135 minutes; P=0.0001) and median intraoperative bleeding was significantly less in the endo-laparoscopic group (0 vs. 100mL; P=0.0001). Two patients in the endo-laparoscopic group were converted to open because of tumor infiltration of the small bowel mesentery causing difficulty in construction of gastrojejunostomy. Although the overall complication rate (13 vs. 17; P=0.387) and incidence of delayed gastric emptying (7 vs. 7, P=0.952) were similar in both groups, the incidence of wound infection was remarkably less common in the endo-laparoscopic group (0 vs. 6, P=0.012). The 15 postoperative complications (13 patients) in the endo-laparoscopic group (38.2%) included prolonged gastric stasis (7), biliary sepsis (2), chest infection (2), myocardial ischemia (2), gastrointestinal bleeding (1) and extensive ischemic stroke (1). Median time to resume diet was statistically shorter in endo-laparoscopic group (5 vs. 7 days, P=0.009) however the hospital stay was similar in both groups (11.5 vs. 14 days, P=0.238). The hospital mortality rate was again comparable between the two groups (6 vs. 5, P=0.703). The short median survival in the endolaparoscopic group (3 vs. 7 months; P=0.0001) might just be a reflection of selection bias. CONCLUSIONS: With the advent of laparoscopic and endoscopic surgery, palliation of both gastric outflow obstruction and obstructive jaundice can also be accomplished using the endo-laparoscopic approach. In comparing to the open double bypass, operation time, intraoperative blood loss and incidence of wound infection are significantly less and patients can have early resumption of diet. However, the results can be improved further with a better patient selection and perioperative optimization.

RESUMO

Gastric outlet obstruction initiated by acute gastric volvulus is rare but potentially fatal. An unusual case of intrathoracic acute gastric volvulus complicated by distal stomach and transverse colon herniation into retrocardial space is reported. Prompt clinical diagnosis was followed by emergency laparoscopic de-rotation and gastropexy.

RESUMO

Haemobilia denotes an abnormal communication between a vessel of the splanchnic circulation and the biliary system. Patients typically presents with the triad of abdominal pain, upper gastrointestinal haemorrhage, and jaundice. Common causes for haemobilia are iatrogenic causes secondary to hepatobiliary system instrumentation and trauma. Management of patients with haemodynamic significant haemobilia is aimed at stopping bleeding, maintaining continuous flow of biliary system, and cure of the underlying aetiology. Iatrogenic haemobilia after ERCP polyethylene biliary endoprosthesis placement is extremely uncommon. Herein we present a case of iatrogenic haemobilia triggered by biliary endoprosthesis placement and was successfully managed by non-operative treatment. The management algorithm for a rational approach to haemobilia is discussed.

RESUMO

BACKGROUND/AIMS: To demonstrate the safety and feasibility of primary closure of the common bile duct (CBD) after laparoscopic choledochotomy in patients with CBD stones. Traditionally, the CBD is closed with T-tube drainage after choledochotomy and removal of CBD stones. However, the insertion of a T-tube is not without complication and the patients have to carry it for several weeks before removal. In the laparoscopic era, surgery is performed with minimally invasive techniques in order to reduce the trauma inflicted on patients, hasten their recovery and hence reduce the hospital stay. T-tube insertion seems to negate these benefits and we believe that primary closure can be as safe as closure with T-tube drainage. METHODOLOGY: This is a retrospective analysis of patients who underwent primary closure of the CBD after successful laparoscopic choledochotomy for ductal stones between January 2000 and December 2003. A concurrent control group of patients who underwent T-tube drainage was used for comparison. RESULTS: Of the 64 patients that underwent laparoscopic exploration of the CBD, 24 (37%) underwent transcystic duct approach and 40 (63%) underwent choledochotomy. There were three open conversions (5%). Stone clearance was achieved in all patients with successful laparoscopic choledochotomy (100%). Of the 38 successful laparoscopic choledochotomies, 12 had primary closure of the CBD and 26 had closure with T-tube drainage. There was no mortality in both groups. One patient in the primary closure group suffered from paralytic ileus and small subhepatic collection which was treated conservatively. The median operative time (90 vs. 120 minutes, p=0.002) and postoperative stay (5 vs. 8.5 days, p=0.003) were shorter in the primary closure group when compared with the T-tube group. CONCLUSIONS: Primary closure of the CBD is feasible and as safe as T-tube insertion after laparoscopic choledochotomy for stone disease.

RESUMO

BACKGROUND: This review investigated the role played by laparoscopic exploration of the common bile duct (LECBD) in the management of difficult choledocholithiasis. METHODS: This retrospective study reviewed a prospective database of LECBD for difficult choledocholithiasis during the period 1995 to 2003. RESULTS: Of the 97 LECBDs performed in the authors' center from 1995 to 2003, 25 were performed for difficult choledocholithiasis. Difficult choledocholithiasis was defined as failure of endoscopic stone retrieval for the following reasons: access and cannulation difficulty, the difficult nature of common bile duct (CBD) stones, and the presence of endoscopic retrograde cholangiopancreatography (ERCP)-related complications. There were seven unsuccessful cannulations because of previous gastrectomy (n = 5) and periampullary diverticulum (n = 2). Among the 18 patients with failed endoscopic extraction, there were 10 impacted stones, 2 incomplete stone clearances after multiple attempts, 2 type 2 Mirizzi syndromes, 1 proximal stent migration, 1 repeated post-ERCP pancreatitis, 1 situs inversus, and 1 stricture at the distal common bile duct. There were 14 male and 11 female patients with a mean age of 67.8 +/- 15 years. Initial presentations included cholangitis (n = 14, 56%), biliary colic (n = 3, 12%), jaundice/deranged liver function ( n = 5, 20%), cholecystitis (n = 2, 8%), and pancreatitis (n = 1, 4%). Regarding the approach for LECBD, there were 2 transcystic duct explorations and 23 choledochotomies. The mean operative time was 149.4 +/- 49.3 min, and there were three conversions (12%). The stone clearance rate was 100%, and no recurrence was detected during a mean follow-up period of 16.8 months. Five complications were encountered, which included bile leak (3 patients) and wound infection (2 patients). When the results were compared with the remaining 72 LECBDs for nondifficult stones during the same period, the complication rate, conversion rate, and rate of residual stones were similar despite a longer operation time (149.4 +/- 49.4 min vs 121.6 +/- 50.5 min). CONCLUSION: When ERCP is impossible or stone retrieval is incomplete, LECBD is the solution to difficult CBD stones.

BACKGROUND: Laparoscopic repair of perforated peptic ulcer was reported in 1990 but has not gained wide acceptance. The aim of this study was to evaluate the safety and efficacy of laparoscopic repair for perforated peptic ulcer in routine clinical practice. METHODS: This was a prospective analysis of 172 patients who underwent laparoscopic repair of a perforated peptic ulcer between July 1997 and June 2003. RESULTS: One hundred and seventy-two patients of mean age 54 (range 14-93) years had perforated peptic ulcer diagnosed by laparoscopy. There were 172 duodenal ulcers, 22 prepyloric and 13 non-juxtapyloric gastric ulcers. One hundred and sixty-five patients underwent omental patch closure of perforations; there were six Pólya gastrectomies and one ulcerectomy. Thirty-seven patients (21.5 per cent) required conversion to laparotomy. The mean operating time was 64.8 (range 14-180) min. The median postoperative requirement for intramuscular pethidine was one dose. The median postoperative hospital stay was 6 days. Complications occurred in 28 patients (16.3 per cent) resulting in three reoperations. Six patients with intra-abdominal collections were managed by percutaneous drainage. Two patients who underwent conversion developed a wound infection. Fourteen patients (8.1 per cent) died, 11 of whom were American Society of Anesthesiologists grade III and IV. CONCLUSION: Laparoscopic repair of perforated peptic ulcer is a safe emergency procedure in routine clinical practice for patients with perforated pyloroduodenal ulcer.

RESUMO

BACKGROUND: This article reports the technical aspects of laparoscopic choledochoduodenostomy (LCD) in patients with recurrent pyogenic cholangitis (RPC) and the perioperative results are also evaluated. This is a retrospective review of a prospectively maintained database. METHODS: Twelve patients diagnosed to have RPC with the absence of intrahepatic stricture were selected for LCD during the period from 1995 to 2002. The majority of our patients had repeated attacks of cholangitis and had already undergone multiple sessions of endoscopic and operative lithotripsy. The LCD was performed using a five-port approach with the patient lying in the supine position. The stones were first cleared through the longitudinal supraduodenal choledochotomy followed by construction of a side-to-side diamond-shaped anastomosis of at least 15 mm between the bile duct and the first part of the duodenum using 2/0 monocryl in the single-layer method. RESULTS: During the period from 1995 to 2002, 12 patients with RPC underwent LCD. There were 3 male and 9 female patients with a mean age of 62 (40-77). The median operation time was 137.5 min (90-270) and the median postoperative stay was 7.5 days (5-20). All cases were successful using the laparoscopic approach. Average analgesic requirement post operation was 126 mg (50-200 mg) intramuscular pethidine. There was one postoperative bile leak, and this complication was settled by conservative measures. Upon a mean follow-up of 37.6 months (6-91), there was no recurrent attack of cholangitis or any evidence of sump syndrome in this group of patients. CONCLUSION: LCD is a safe and effective drainage procedure for patients with RPC. Complications are uncommon and postoperative results are promising.
