Laparoscopic anterior resection: a consecutive series of 84 patients.

Laparoscopic colorectal surgery is in its infancy. From a series of over 200 colorectal procedures undertaken over the last 30 months, we have performed 84 anterior resections. In 55 women and 29 men, median age 64 years (range 32-86), median weight 72 kg (range 36-125), surgery was undertaken for benign pathology (n = 57) and adenocarcinoma (n = 27). Anterior resection was completed laparoscopically in 75 cases (89%) with a median operating time of 210 min (range 85-420). Minor morbidity occurred in 17 patients (20%) with major morbidity in 10 cases (12%). There was one post-operative death. Flatus was passed a median of two days (range 1-7) after surgery and feces at a median of four days (range 2-9). Total hospital stay was six days (range 2-33). Delayed morbidity during a maximum of 30 months' follow-up included two anastomotic strictures but no evidence of malignant seeding. Laparoscopic anterior resection appears both feasible and safe for both benign and malignant disease, with the caveat that long-term outcome in malignant disease is not yet available.

Laparoscopic exploration of the common bile duct: lessons learned from 129 consecutive cases.

Since the introduction of laparoscopic cholecystectomy there has been widespread debate about the best way to manage common bile duct (CBD) calculi. Between August 1991 and July 1994, 129 patients underwent laparoscopic exploration of the CBD. Fifteen patients of median age 52 years were managed by glucagon-induced relaxation of the sphincter of Oddi and saline flushing of the bile duct through a cholangiogram catheter. This had a success rate of 73 per cent and took a median of 90 min including cholecystectomy. The technique has now been replaced by Dormia basket exploration of the CBD. Transcystic common duct exploration using a Dormia basket was used in 79 patients of median age 47 years. Duct clearance was achieved in 96 per cent of cases with a median operating time of 55 min. Thirty-five patients of median age 52 years were managed by choledochotomy and T tube placement, with a 91 per cent duct clearance rate and a median operating time of 120 min. Overall duct clearance was achieved in 92 per cent of patients with an operative morbidity rate of 5.4 per cent. Duct clearance using either a Dormia basket or choledochotomy and T tube placement was obtained in 95 per cent of patients. Laparoscopic exploration of the CBD is an important alternative in the management of common duct calculi.

Laparoscopic antegrade biliary stenting.

BACKGROUND AND STUDY AIMS: Laparoscopic common bile duct exploration is successful in 90% of patients, but 10% of patients may have retained stones or impaired biliary drainage at the end of surgery. This study presents the results of laparoscopic biliary stenting in three such patients. PATIENTS AND METHODS: Three patients with choledocholithiasis, aged 51, 82, and 100 were treated by laparoscopic antegrade placement of biliary stent. RESULTS: Biliary drainage was established in all three cases. Follow-up at six months revealed all patients to be asymptomatic, with two aged 82 and 101 with the stents still in place. CONCLUSIONS: Laparoscopic antegrade biliary stenting deserves consideration when the surgeon encounters impaired biliary drainage after laparoscopic exploration of the common bile duct.

Laparoscopic splenectomy and lymph node biopsy for hematologic disorders.

OBJECTIVE: The authors audit the introduction of laparoscopic splenectomy and laparoscopic intra-abdominal lymph node biopsy and compare outcomes with a parallel cohort of patients undergoing open splenectomy. SUMMARY BACKGROUND DATA: Laparoscopic splenectomy was first reported in 1992. It was introduced into clinical practice at the Royal Brisbane Hospital in 1991. Between June 1991 and March 1994, 24 patients have undergone laparoscopic splenectomies and 23 patients have had laparoscopic intra-abdominal lymph node biopsies. METHODS: Laparoscopic splenectomy was performed using a four- or five-port technique. The splenic hilum was secured using a linear stapler cutter, and the spleen was removed after placing it in a laparoscopic bag. Lymph node biopsy was performed using a three- or four-port technique, depending on the site and size of the lymphadenopathy. RESULTS: Laparoscopic splenectomy was completed in 22 patients (92%). Median hospital stay was 3 days (range 2-7 days) and morbidity occurred in two patients (8%). Lymph node biopsy was completed laparoscopically in 21 of 23 patients (91%), with morbidity in two cases (9%). Median hospital stay was 2 days (range 1-6 days), with a diagnostic accuracy of 90%. Comparison with open splenectomy revealed that the laparoscopic approach took significantly longer to perform (p = 0.0002), but resulted in a significantly shorter hospital stay (p = 0.0005). CONCLUSIONS: Both laparoscopic splenectomy and laparoscopic lymph node biopsy currently are used as the treatments of choice for hematologic disease in our institution.

Laparoscopic biliary and gastric bypass: a useful adjunct in the treatment of carcinoma of the pancreas.

Over 90% of patients with inoperable carcinoma of the pancreas are successfully palliated by endoscopic retrograde cholangiopancreatography and stent insertion. Treatment of the residual 10% of patients often entails a laparotomy, which is difficult to justify when median survival of these patients is only 150 days. Laparoscopic biliary and gastric bypass offers a less invasive alternative than open surgery with shorter hospital stay and more rapid return to normal activity. Between August 1991 and March 1994, 16 patients (median age 69 years, range 31-85) had laparoscopic bypass surgery. The indications for surgery were gastric outlet obstruction at initial presentation (n = 4), blocked biliary stent (n = 8), and metastatic tumour at laparoscopy (n = 4). Surgery took the form of cholecystjejunostomy (n = 7), gastroenterostomy (n = 5), both procedures (n = 3), and failed operation (n = 1). Operative duration was 75 minutes (range 45-190) and hospital stay four days (range 3-33) and all apart from two patients were discharged from hospital in seven days or less. Morbidity occurred in two patients (13%) in the form of a cerebrovascular accident and delayed gastric emptying. Median survival in 10 patients who have died is 201 days (range 20-525). Laparoscopic biliary and gastric bypass is possible in most patients in whom endoscopic stenting has failed and in those who subsequently develop gastric outlet obstruction. Hospital stay is shorter than after open surgery and recovery more rapid.

Severe pancreatitis--still a frequently mortal illness.

The treatment of severe pancreatitis remains a challenge. Eighty-six cases were retrospectively reviewed after treatment in intensive care units at two major Brisbane Hospitals between January 1980 and May 1986. Thirty-three patients died. Sixty-one patients had 97 operations, with 40% mortality. The severity of biliary and postoperative pancreatitis is highlighted. After early detection and aggressive resuscitation of severe cases, repeated debridement of necrotic pancreas and retroperitoneal slough may offer the best treatment. Marsupialization is an effective method of controlling sepsis after necrosectomy and abscess drainage.

Morbidity and mortality of operative intubation for malignant oesophageal obstruction.

In 33 patients who underwent operative intubation of carcinoma of the oesophagus or gastric cardia, there were nine postoperative deaths (mortality 27%). Only 15 patients (46%) had no further operative procedure or anaesthetics, but their mean survival was only 3.7 months. Nine patients (27%) required a total of 17 procedures after the placement of their original tube. Operative intubation has a similar mortality to resection but the survival times are short. Whenever possible palliative resection or endoscopic intubation is to be recommended.
