Outcome of video-assisted translumbar retroperitoneal necrosectomy and closed lavage for severe necrotizing pancreatitis.

INTRODUCTION AND OBJECTIVE: Surgery for necrotizing pancreatitis is associated with a high rate of morbidity and mortality. We present a series of 26 patients who underwent video-assisted translumbar retroperitoneal necrosectomy and analyse their outcomes. METHODS: Records of 26 patients who underwent video-assisted translumbar retroperitoneal necrosectomy and closed drainage for infected pancreatitic necrosis between January 2008 and March 2012 were reviewed, retrospectively. RESULTS: Twenty-three out of 26 patients were males, with a mean age of 38.6 (±9.9) years. Alcohol was the aetiology in 18 patients, gall stones in 7, and in 1 it was idiopathic. The mean duration of symptoms before patients were taken up for surgery was 47.2 (±34.8) days. The mean computed tomography severity index was 7.7 (±1.2). All patients had undergone video-assisted retroperitoneal necrosectomy through a limited left lumbar incision. Post-operative lavage was given through drains placed in the retroperitoneum. Three patients required re-exploration. Eleven patients developed complications and there were two mortalities. The median intensive care unit (ICU) stay was 4 days (range 2-14 days). The mean post-operative hospital stay was 22.5 (±6.6) days. CONCLUSION: Video-assisted translumbar retroperitoneal necrosectomy followed by closed lavage of infected pancreatic necrosis in select cases of infected pancreatic necrosis was associated with a low rate of ICU stay, hospital stay and need for re-entry.

Isolated caudate lobe resection: technical challenges.

BACKGROUND: Isolated caudate lobe resection remains a technical challenge even in the best hands. This is due to the difficult approach and its location between major vessels. This retrospective study aims to analyze our experience with isolated caudate lobe resections. METHODS: Of the 402 patients who underwent liver resections between January 2002 and December 2011, we identified 13 caudate lobectomies. We analyzed the operative parameters, hospital stay, morbidity and follow up of these patients. RESULTS: There were nine males and four females, age ranging between 30 and 72 years. The indications were hepatocellular carcinoma in nine patients, hilar cholangiocarcinoma in two, solitary fibrous tumor in one, and a regenerative nodule in one patient. Left-sided approach was employed in seven cases, right-sided approach in three cases and a combined approach in three cases. Operating time ranged between 125 and 225 min and blood loss ranged between 210 and 630 mL. There was no mortality in the post-operative period. No local recurrence was noted in the follow-up period ranging from 6 months to 7 years. CONCLUSION: Caudate lobe resections, although technically challenging, can be successfully performed with minimal blood loss. Surgery offers potential cure in isolated caudate lobe tumors. The location and size of the tumor decides the approach.

Biliary cystadenomas: a case for complete resection.

Introduction and Objective. Biliary cystadenoma is a rare benign neoplasm of the liver with less than 200 cases being reported allover the world. We report a series of 13 cases highlighting the radiological findings and problems related to its management. Materials and Methods. Records of thirteen patients who underwent surgery for biliary cystadenomas, between March 2006 and October 2011, were reviewed retrospectively. Results. Majority of the patients were females (11 out of 13), with a median age of 46 (23-65) years. The most frequent symptom was abdominal pain (92%). Seven patients had presented with history of previous surgery for liver lesions. Five patients had presented with recurrence after partial resection for a suspected hydatid cyst and two after surgery for presumed simple liver cyst. Ten of the 13 patients had complete resection of the cyst with enucleation in 3 patients, 2 of whom in addition required T-tube drainage of the bile duct. There has been no recurrence during the follow-up period ranging from 3 months to 5 years. Conclusion. Biliary cystadenoma must be differentiated from other benign cysts. Hepatic resection or cyst enucleation is the recommended treatment option.
