Experience with Laparoscopic and Robotic Colon Surgery Together with Other Major Minimally Invasive Procedures for Unrelated Pathologies.

Background: Indications for combined colon surgery together with other procedures include oncologic multivisceral resections and abdominal trauma. It is unclear if combining minimally invasive (MI) colon surgery with unrelated other procedures increases the risk for complications. Patients and Methods: The surgical database from two institutions during a 10-year period was queried for combined colon surgeries together with other interventions. All open cases, combined cases performed for one pathology and MI colectomies together with a minor procedure, were excluded. Results: Median age of the 6 men and 7 women was 64.4 (range 42.7-75.4) years. Colon surgeries included right (5), sigmoid (4) transverse (1) colectomies, rectum resection (1), rectopexy (1), and colostomy reversal (1) with indications of colorectal cancer (5), diverticulitis (3), benign ileocecal mass (1), colonic volvulus (3) and rectal prolapse (1). Second procedures included two splenectomies (sarcoidosis, ITP), paraesophageal hernia repairs (4), right diaphragmatic repairs [eventration (2) and Morgagni type hernia]; cholecystectomies (2), appendectomy (acute appendicitis), duodenal wedge resection (carcinoid), reversal of a gastric bypass (Roux limb stricture) one each. Cases were done laparoscopically (7) and robotic assisted (6). In most cases only 4 trocars were used. Median OR time was 4.3 (range 2.5 to 6.6) hours. No anastomotic breakdown was observed. Conclusions: Combining MI colectomy and other major abdominal surgeries can be safely done and in this series did not increase morbidity or mortality but avoids a second operation. Patient selection seems important and port placement may need to be altered to achieve good exposure for both procedures.
