Background: With the increasing incidence of proximal gastric cancer, laparoscopic proximal gastrectomy has been applied. However, reflux esophagitis often occurs after traditional esophagogastric anastomosis. In order to solve this problem, several methods of digestive tract reconstruction have emerged, but the most satisfying method remains to be discussed. Therefore, we modified traditional Kamikawa anastomosis to investigate the appropriate digestive tract reconstruction in laparoscopic proximal gastrectomy.

Aim: To discuss the clinical efficacy of modified Kamikawa anastomosis in laparoscopic proximal gastrectomy.

Methods: A retrospective case series was adopted. Clinicopathological data were collected from 26 patients who underwent laparoscopic proximal gastrectomy and modified Kamikawa anastomosis at our hospital from January 2020 to September 2022. The operation conditions, postoperative recovery, postoperative complications, and follow-up data were collected and analyzed.

Results: All the patients were successfully operated on without conversion to laparotomy. The duration of operation and digestive tract reconstruction were 203.500 (150-224) min and 87.500 (73-111) min, respectively. The intraoperative amount of bleeding was 20.500 mL ± 0.696 mL. The time of postoperative first flatus, the first postoperative fluid intake, and the postoperative length of stay were 2 (1-3) d, 4 (3-5) d, and 9 (8-10) d, respectively. All the patients were followed up for 12-23 months. The body mass index at 6 and 12 months after surgery were 22.577 kg/m ± 3.098 kg/m and 22.594 kg/m ± 3.207 kg/m, respectively. The nutrition risk screening 2002 score, the patient-generated subjective global assessment score, and the gastroesophageal reflux disease scale score were good at 6 and 12 months after surgery. Reflux esophagitis and anastomotic stenosis were not observed in any of the patients during their 12-month postoperative gastroscopy or upper gastrointestinal tract visits. All the patients exhibited no tumor recurrence or metastasis.

Conclusion: The modified Kamikawa anastomosis is safe and feasible for laparoscopic proximal gastrectomy and has good antireflux effects and nutritional status.

Single-incision plus one-port laparoscopic proximal gastrectomy with double-channel anastomosis (SILT-DT) is a minimally invasive surgical approach for treating proximal gastric cancer. This technique includes comprehensive laparoscopic resection of the proximal stomach, lymph node dissection, and double-tract anastomosis. By integrating single-port laparoscopic surgery with an auxiliary operating hole, SILT-DT reduces procedural difficulty while facilitating the placement of an abdominal drainage tube.

Background: Sacrocolpopexy has become a favored treatment of pelvic organ prolapse due to its durability and efficacy. Sacrocolpopexy has not been standardized and there is no categorization scheme to facilitate communication or research efforts for the procedure. A systematic review was conducted to facilitate construction of a classification system for sacrocolpopexy based on extent of vaginal dissection described in the medical literature.

Gall Stone Ileus and Recurrence: Management Dilemma for the Operating Surgeon.

Gallstone ileus (GSI) is a rare complication of gallstone disease. It occurs as a result of the passage of a stone from the biliary tract into the gastrointestinal tract via an abnormal pathway (bilio-enteric fistula). Chronic inflammatory processes result in gall bladder adhering and subsequently eroding into the intestines, leading to a fistula.

Article Synopsis
  • The study investigates the effectiveness of 3D virtual modeling (3DVM) and indocyanine green perfusion angiography (ICGPA) in improving surgical planning and outcomes during laparoscopic right hemicolectomy for colon cancer.
  • Advanced imaging techniques allowed for precise preoperative planning, showing a high correlation with intraoperative findings, which enabled better decisions regarding vessel management and anastomotic site selection.
  • The results indicate that using 3DVM and ICGPA not only enhances the surgical team’s ability to visualize vascular structures but also leads to successful surgeries without postoperative complications.

A primary pull-through for Hirschsprung's disease (HD) requires confirmation of normal ganglionic bowel by intraoperative biopsies to determine the level of resection. Despite this, aganglionic bowel that is not fully resected (so-called "transition zone pull-throughs") is reported in 15%-19% of patients. We hypothesize that this may result from insufficient biopsies sent for intraoperative diagnosis.
