We report a patient with HBV-related hepatocellular carcinoma （HCC） and refractory ascites who had received a peritoneal-venous shunt （PVS） 1 year before liver transplantation, Urgent surgical intervention following bowel obstruction and failure of immunosuppression therapy. No intestinal obstruction was found during an initial PVS. However, intestinal obstruction developed 2 was found upon exploration. This is the first reported case of cocoon abdomen caused by PVS and exacerbated by liver transplantation.

A diagnosis of intestinal diverticulosis is difficult to make pre-operatively because the clinical symptoms are usually non-specific. We report the case of a 70-year-old man who had suffered from three episodes of intestinal obstruction in 1 year. He experienced dull pain and a sensation of fullness over the whole abdomen. The symptoms did not improve after conservative *** presumptive diagnosis was intestinal obstruction, and an exploratory laparotomy found diverticulosis of the proximal jejunum, with an adhesion band formed from the base of one diverticulum. Strangulation of a segment of the jejunum resulted from the internal herniation caused by the band. The band was removed and the proximal jejunum segmentally resected. His postoperative course was uneventful.

Background: A 35-year-old married female (68 kg, 150 cm, BMI: 30.2) with pancreatic divisum complicated chronic pancreatitis and underwent pylorus-preserving pancreaticoduodenectomy in 2010. After that, her condition was well. However, body weight gained progressively to 76 kg (BMI: 33.7) and hypertension developed. During these two years, tried exercise and medication control for hypertension, but in vain. She received a laparoscopic sleeve gastrectomy in October 2013. The post-operative course was uneventful. Methods: We applied three ports for laparoscopic operation, including two 12 mm and one 5 mm trocars. The liver was not needed to be elevated due to adhesion. The operative time was 75 minutes. Results: The patient’s body weight was 10 kg reduced in the first two months and reduced to 59 kg 6 months later. Conclusions: We report a case that received laparoscopic sleeve gastrectomy following pylorus-preserving pancreaticoduodenectomy due to pancreatic divisum. This case encourages us to extend the indication of laparoscopic sleeve gastrectomy.

Background: Ten-millimeter ports are often used in laparoscopic surgery. It could be difficult to close the ports sites, especially in obese patients. We described a new method to close ten-millimeter port-site wounds, effective and easily to perform. Methods: Forty cases of laparoscopic bariatric surgery were performed from April 2010 to September 2011 at IRCAD Taiwan. Among them, 30 patients received trocar hole closed with SURGICEL® Original Hemostat and the other 10 patients received trocar hole closed with autologous fat. The results were recorded. Results: In group of SURGICEL® Original Hemostat, includes 21 female and 9 male, age range from 18 to 54 with average 39.5 years. Average BMI is 42.4 (range from 32.6 to 55). The operations include 27 cases of laparoscopic sleeve gastrectomy, 2 cases of laparoscopic gastric bypass, and 1 case of laparoscopic mini-bypass. Group of autologous fat includes 3 female and 7 male, age range from 20 to 49 with average 38.6 years. Average BMI is 39 (range from 32.8 to 64.5). The operations include 9 cases of laparoscopic sleeve gastrectomy, and 1 case of laparoscopic mini-bypass. No complications of trocar wound including infection, hematoma, and hernia were found for a mean follow-up of 6 months. Conclusions: For obese patients, closure of port sites can be difficult. We described a method of closing 10-mm port-sites wounds, which are easy, effective, and not required any special instruments.

Purpose: Perforated peptic ulcer is an emergency condition. Laparoscopic ulcer repair is a feasible and safe procedure. The aim of this study was to research the efficacy of laparoscopic repair of peptic ulcer and to discuss the causes of conversion from laparoscopy to laparotomy. Methods: We collected 34 patients with perforated peptic ulcer underwent laparoscopic surgery from October 2003 to October 2008. Thirty four patients with perforated peptic ulcer underwent laparoscopic intervention and 6 cases were converted to laparotomy. The demographics, laboratory data, perioperative data, morbidity and mortality were compared. Results: In demographics of two groups, there were no significant differences in sex, age, location, and mean duration of symptoms of acute abdominal pain. However, there were significant differences in median size of perforation, mean duration of history of peptic ulcer related pain, and the experiences of surgeon. There were no significant differences in the laboratory data and perioperative data of two groups. In morbidity?and mortality of two groups, there were no significant differences in leakage, wound infection, intra-abdominal abscess, ileus, urinary tract infection, pneumonia, and mortality, but there was significant difference in overall morbidity in two groups. Conclusions: Laparoscopic repair of perforated peptic ulcer is safe and could be used in routine clinical practice. However, patients with larger perforations (>10 mm), longer duration of history peptic ulcer related pain (>2 years), and learning curve of surgeon could be associated with conversion rate. It is associated with higher morbidity in patients with conversion from laparoscopy to laparotomy.

Background: Totally implantable access ports (TIAP) could be done in two methods: puncture of subclavian vein and cephalic vein cutdown. Cephalic vein cutdown method has fewer complications but has higher failure rates. We present a method to decrease the failure rates. Methods: We use the continuously injection with diluted heparin solution via catheter while introducing the TIAP catheter into the cephalic vein. Results: From January 2005 to January 2009, 20 patients were performed. This method was successfully applied in 11 patients with no complications. The other 9 patients was unsuccessfully and further underwent guidewire assisted. Conclusions: Continuously injection with diluted heparin solution via catheter while inserting TIAP catheter into the cephalic vein is safe and simple. It could be used for difficulties of insertion of TIAP and increased the successful rates of cephalic vein cut-down method.

Background: To present the experience of management of leaks following laparoscopic sleeve gastrectomy for morbid obesity in Show-Chwan memorial Hospital. Patients and Methods: Laparoscopic sleeve gastrectomy is considered one of the surgical options for morbid obesity. It is effective, with an average loss of 50% of excessive weight after 2 years of follow-up. The first laparoscopic sleeve gastrectomy was performed in January 2010 at Show-Chwan Memorial Hospital. Between January 2010 and October 2016, 300 patients underwent laparoscopic sleeve gastrectomy for morbid obesity. There were 218 women and 82 men with a mean age of 35.4 years. Preoperative mean body weight was 90.7 kg and mean body mass index (BMI) was 37.3 kg/m2. Results: Mean operative time was 85 minutes. Mean hospital stay was 3.5 days. There were no deaths. There were 5 complications (1.67%): leakage of gastroesophageal junction. One patient was conservative treatment. Two patients were successfully treated by self-expandable metallic stents and the other two patients were treated with esophageal stent also, but failed and further treated with fibrin (Histoacryl) injection to the leak site to try to seal the fistula. In six months follow-up, mean BMI decreased from 37.3 to 29.2 kg/m2, and mean excess weight loss reached 42.8%. Conclusions: Laparoscopic sleeve gastrectomy is a beneficial operation in terms of excessive weight loss, with acceptably complications. The leaks were located in gastroesophageal junction mostly, and could be resolved with esophageal stent. For the patients failed in esophageal stents, we try Histoacryl injection to improve it.
