This tension-free hiatoplasty seems to be an effective solution to prevent postoperative paraesophageal hernia in patients undergoing antireflux laparoscopic surgery. However, longer follow-up is still needed.
Background Routine drainage after laparoscopic cholecystectomy is still debatable. The present study was designed to assess the role of drains in laparoscopic cholecystectomy performed for nonacutely inflamed gallbladder. Methods After laparoscopic gallbladder removal, 53 patients were randomized to have a suction drain positioned in the subhepatic space and 53 patients to have a sham drain. The primary outcome measure was the presence of subhepatic fluid collection at abdominal ultrasonography, performed 24 h after surgery. Secondary outcome measures were postoperative abdominal and shoulder tip pain, use of analgesics, nausea, vomiting, and morbidity. Results Subhepatic fluid collection was not found in 45 patients (84.9 %) in group A and in 46 patients (86.8 %) in group B (difference 1.9 (95 % confidence interval -11.37 to 15.17; P = 0.998). No significant difference in visual analogue scale scores with respect to abdominal and shoulder pain, use of parenteral ketorolac, nausea, and vomiting were found in either group. Two (1.9 %) significant hemorrhagic events occurred postoperatively. Wound infection was observed in three patients (5.7 %) in group A and two patients (3.8 %) in group B (difference 1.9 (95 % CI -6.19 to 9.99; P = 0.997). Conclusions The present study was unable to prove that the drain was useful in elective, uncomplicated LC.
Stapled hemorrhoidopexy is a safe and effective treatment for Grade III and Grade IV hemorrhoids. Recurrence requiring reoperation was higher in Grade IV hemorrhoids than in Grade III hemorrhoids.
We studied the effect of combined chemo-immunotherapy, 5-FU followed by thymosin alpha 1 (T alpha 1) and interleukin-2 (IL-2) at low doses, on liver metastases from colorectal cancer, induced by splenic injection of DHD/K12 cells (1,2-dimethylhydrazine-induced colon adenocarcinoma) in syngeneic BDIX rats. The presence of liver metastases was checked by laparotomy 14 days after tumor-cell injection. Evaluable rats were assigned randomly to 5 experimental groups designated as control, 5-FU, IL-2, 5-FU/IL-2 and 5-FU/T alpha 1/IL-2. 5-FU was administered i.v. as a continuous infusion for 7 days by an osmotic device implanted surgically. T alpha 1 and IL-2 were administered for 4 days and repeated after 11 days. Combined chemo-immunotherapy was shown both to significantly reduce the growth of liver metastases and to prevent extra-hepatic spread. 5-FU/T alpha 1/IL-2 also improved survival rate. Combined immunotherapy after 5-FU restored NK activity of the peripheral-blood-mononuclear-cell (PBMC) in tumor and/or 5-FU immunodepressed rats and enhanced PBMC cytotoxic activity against the DHD/K12 autologous cell line. This model was devised to mimic the clinical situation of unresectable liver metastases.
Drainage after laparoscopic cholecystectomy (LC) for acute calculous cholecystitis (ACC) is used without evidence of its efficacy. The present pilot study was designed to address this issue. After laparoscopic gallbladder removal, 15 patients were randomized to have a drain positioned in the subhepatic space (group A) and 15 patients to have a sham drain (group B). The primary outcome measure was the presence of subhepatic fluid collection at abdominal ultrasonography, performed 24 h after surgery. Secondary outcome measures included postoperative abdominal and shoulder tip pain, use of analgesics, and morbidity. Abdominal ultrasonography did not show any subhepatic fluid collection in eight patients (53.3 %) in group A and in five patients (33.3 %) in group B (P00.462). If present, median (range) subhepatic collection was 50 mL (20-100 mL) in group A and 80 mL (30-120 mL) in group B (P00.573). No significant differences in the severity of abdominal and shoulder pain and use of parenteral ketorolac were found in either group. Two biliary leaks and one subhepatic fluid collection occurred postoperatively. The present study was unable to prove that the drain was useful in LC for ACC, performed in a selected group of patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
