Clinical results between single incision laparoscopic cholecystectomy and conventional 3-port laparoscopic cholecystectomy: prospective case-matched analysis in single institution

Purpose The aim of our study was to compare single incision laparoscopic cholecystectomy (SILC) and conventional laparoscopic cholecystectomy (CLC) with respect to clinical outcomes. Methods Patients with less than a 28 body mass index (BMI) and a benign gall bladder disease were enrolled in this study. From January 2011 to February 2012, 30 consecutive patients who underwent SILC were compared with 30 patients who underwent CLC during the same period. In this study, all operations were performed by one surgeon. In each group, patient characteristics and perioperative data were collected. Results There was no significant difference in the preoperative characteristics. There was no significant difference in the postoperative laboratory result (alanine aminotransferase, aspartate aminotransferase, and alanine aminotransferase), number of conversion and complication cases, and length of hospital stay. The operation time was significantly longer in the SILC group (78.5 ± 17.8 minutes in SILC group vs. 34.9 ± 5.75 minutes in CLC group, P < 0.0001). The total nonsteroidal antiinflammatory drug usage during perioperative period showed significantly higher in SILC groups (162 ± 51 mg in the SILC group vs. 138 ± 30 mg in the CLC group), but there was no statistically significant difference in opioid usage between two groups. The postoperative pain score was significantly higher in the SILC group at second, third, and tenth postoperative day. Satisfaction of postoperative wound showed superiority in SILC group. Conclusion SILC seems to be an acceptable alternative to CLC with acceptable results. However, it is not enough to propose any real benefits of SILC when compared with CLC in terms of operation time and postoperative pain.

Chylous ascites caused by acute pancreatitis with portal vein thrombosis

Chylous ascites is defined as the accumulation of chyle in the peritoneum due to obstruction or rupture of the peritoneal or retroperitoneal lymphatic glands. Chylous ascites that arises from acute pancreatitis with portal vein thrombosis is very rare. We report here on a case of chylous ascite that was caused by acute pancreatitis with portal vein thrombosis, in which the patient showed an impressive response to conservative therapy with total parenteral nutrition and octerotide. We also review the relevant literature about chylous ascites with particular reference to the management of this rare disease.

Partial gastric outlet obstruction caused by a huge submucosal tumor originating in the heterotopic pancreas

A 21-year-old woman presented gastrointestinal manifestation showing intermittent abdominal pain, nausea, and vomiting. An upper endoscopic examination showed round, elevated mucosa at the antrum of the stomach anterior wall. After CT scanning, a huge degenerated gastrointestinal stromal tumor was suspected. Subtotal gastrectomy with Billroth II anastomosis was performed. Histologically, pseudocystic degeneration of the heterotopic pancreas was confirmed. The patient showed eventful postoperative course except temporary dilated gastric emptying. The patient is doing well without any abnormal symptom at 8-month follow-up. This report is a rare case of gastric outlet obstruction caused by a pseudocyst originating from a heterotopic pancreas in the gastric antrum.
