Prior abdominal open surgery does not impair outcomes of laparoscopic colorectal surgery: a case-control study in 367 patients

Colorectal surgery in patients with prior pancreaticoduodenectomy

Objectives: Colorectal cancer (CRC) surgery after pancreaticoduodenectomy (PD) is difficult to perform, because PD involves dissection and complex reconstruction of the digestive tract. We evaluated the clinical outcomes of CRC surgery in patients with prior PD. Methods: Between January 2008 and March 2018, a total of 1727 patients received CRC surgery at our institution. Of these, 10 had previously undergone PD (PD group). As a control group, 280 patients were collected who had undergone resection without any history of previous abdominal surgery. The PD and control groups were further subdivided into four groups by right or left side. Outcomes of colorectal surgery were investigated in the PD and control groups. Results: The number of harvested lymph nodes was significantly lower in the PD group. In the right colectomy group, distance from the surgical margin was significantly shorter in the PD group. The rate of postoperative complications was higher in the PD group. Peritoneal dissemination originating from pancreatic cancer was found during CRC surgery for one patient, and one patient developed refractory ascites. Three patients died of pancreatic cancer, rectal cancer, and other disease. Seven patients were alive without recurrence. Conclusions: CRC surgery for patients with prior PD can involve difficulty in dissecting lymph nodes and higher postoperative morbidity rates but can provide sufficiently curative resection for CRC.

What is the outcome for patients undergoing more than two ileocolonic resections for recurrent Crohn's disease? A comparative study of 569 consecutive procedures

AIM

To assess the outcome for patients undergoing repeated ileocolonic resection for recurrent Crohn's disease (CD).

METHOD

All patients undergoing ileocolonic resection for terminal ileal CD between 1998 and 2016 in our tertiary care centre were retrospectively reviewed.

RESULTS

Between 1998 and 2016, 569 ileocolonic resections were performed for CD: 403 of these were primary resections (1R, 71%), 107 second resections (2R, 19%) and 59 were third (or more) resections (> 2R, 10%). The laparoscopic approach rate was significantly less in the > 2R group (20/59, 34%) compared with the 2R (71/107, 66%; P = 0.002) and 1R (366/403, 91%) groups. However, conversion to an open approach did not show any difference between the three groups [1R group 46/366 (13%) vs 2R group 14/71 (20%) vs > 2R group 3/20 (15%); 1R vs > 2R P = 0.750; 2R vs > 2R P = 0.633]. Postoperative morbidity was significantly increased in the > 2R (28/59, 52%) group compared with the 1R group (115/403, 29%; P < 0.001) but showed no difference compared with the 2R group (43/107, 40%; P = 0.365). There was no difference between the groups in the incidence of severe postoperative morbidity (Clavien-Dindo ≥ 3) [1R group n = 24 (6%); 2R group n = 6 (6%); > 2R group n = 4, 7%; 1R vs > 2R P = 0.865, 2R vs > 2R P = 0.761].

CONCLUSION

Although the overall morbidity rate was higher, repeated surgery for recurrent CD in patients undergoing three or more ileocolonic resections was not associated with an increased risk of severe postoperative morbidity in our series.

Laparoscopic Colorectal Surgery in Patients With Previous Abdominal Surgery: A Single-center Experience and Literature Review

To present the outcomes of laparoscopic colorectal surgery in colorectal cancer patients with a previous history of abdominal surgery. Data of a total of 121 patients with primary colorectal cancer who underwent laparoscopic surgery were retrospectively analyzed. The patients were divided into 2 groups as those with previous abdominal surgery (PAS, n=34) and those without (non-PAS, n=87). Gastric and colonic surgeries were the most common procedures in the major PAS group, whereas gynecologic and obstetric surgeries and appendectomy were the most common procedures in the minor PAS group. However, there were statistically significant differences in the overall complication rates, wound complications, and anastomotic leaks, although there were no significant differences in the rates of postoperative ileus, pneumonia, port site herniation, and postoperative bleeding between the groups. Our study results suggest that laparoscopic colorectal surgery can be safely performed in patients with colorectal cancer who underwent abdominal surgery previously.

Laparoscopic surgery for sigmoid colon cancer after multiple operations including urinary diversion with Indiana pouch: A case report

A 73-year-old man with lower abdominal pain was diagnosed at our hospital with sigmoid colon cancer. He had previously undergone radical cystectomy with Indiana pouch construction and gastrectomy to treat bladder cancer and gastric cancer, respectively. We performed a laparoscopic Hartmann's operation with Japanese D3 lymph node dissection. We observed severe adhesion in the abdominal cavity; adhesions between the urostomy and sigmoid colon were particularly severe. The tumor had invaded to the distal rectum, which had adhered to the pubic bone and the previously reconstructed urinary pouch. By performing careful and persistent laparoscopic dissection, we completed the operation without damaging the urostomy and with no remnant tumor tissue (R0). The postoperative course was uneventful, and the patient was doing well with no evidence of cancer recurrence 1 year after surgery.

Short-term outcomes after laparoscopic colorectal surgery in patients with previous abdominal surgery: A systematic review

AIM: To perform a systematic review focusing on short-term outcomes after colorectal surgery in patients with previous abdominal open surgery (PAOS).

METHODS: A broad literature search was performed with the terms “colorectal”, “colectomy”, “PAOS”, “previous surgery” and “PAOS”. Studies were included if their topic was laparoscopic colorectal surgery in patients with PAOS, whether descriptive or comparative. Endpoints of interest were conversion rates, inadvertent enterotomy and morbidity. Analysis of articles was made according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

RESULTS: From a total of 394 citations, 13 full-texts achieved selection criteria to be included in the study. Twelve of them compared patients with and without PAOS. All studies were retrospective and comparative and two were case-matched. The selected studies comprised a total of 5005 patients, 1865 with PAOS. Among the later, only 294 (16%) had history of a midline incision for previous gastrointestinal surgery. Conversion rates were significantly higher in 3 of 12 studies and inadvertent enterotomy during laparoscopy was more prevalent in 3 of 5 studies that disclosed this event. Morbidity was similar in the majority of studies. A quantitative analysis (meta-analysis) could not be performed due to heterogeneity of the studies.

CONCLUSION: Conversion rates were slightly higher in PAOS groups, although not statistical significant in most studies. History of PAOS did not implicate in higher morbidity rates.

Role of Minimally Invasive Surgery in the Reoperative Abdomen or Pelvis

Laparoscopy has become widely accepted as the preferred surgical approach in the management of benign and malignant colorectal diseases. Once considered a relative contraindication in patients with prior abdominal surgery (PAS), as surgeons have continued to gain expertise in advanced laparoscopy, minimally invasive approaches have been increasingly incorporated in the reoperative abdomen and pelvis. Although earlier studies have described conversion rates, most contemporary series evaluating the impact of PAS in laparoscopic colorectal resection have reported equivalent conversion and morbidity rates between reoperative and non-reoperative cases, and series evaluating the impact of laparoscopy in reoperative cases have demonstrated improved short-term outcomes with laparoscopy. The data overall highlight the importance of case selection, careful preoperative preparation and planning, and the critical role of surgeons' expertise in advanced laparoscopic techniques. Challenges to the widespread adoption of minimally invasive techniques in reoperative colorectal cases include the longer learning curve and longer operative time. However, with the steady increase in adoption of minimally invasive techniques worldwide, minimally invasive surgery (MIS) is likely to continue to be applied in the management of increasingly complex reoperative colorectal cases in an effort to improve patient outcomes. In the hands of experienced MIS surgeons and in carefully selected cases, laparoscopy is both safe and efficacious for reoperative procedures in the abdomen and pelvis, with measurable short-term benefits.

Laparoscopy in Crohn's disease

In Crohn's disease (CD) surgical management, laparoscopic approach offers several theoretical advantages over the open approach. However, the importance of inflammatory lesions associated with CD, and the frequent presence of adhesions from previous surgery have initially questioned its feasibility and safety. In the present review article we will discuss the role of laparoscopic approach for Crohn's disease surgical management, along with its potential benefits as compared to the open approach.

Surgical management of IBD--from an open to a laparoscopic approach

Surgery is a key feature of IBD management. Up to 70% of patients with Crohn's disease and 35% of patients with ulcerative colitis will require surgery during the course of their disease. This Review provides an overview of IBD surgical management, focusing on the potential benefits and drawbacks of laparoscopy compared with open surgery. Emergency and elective indications for both laparoscopic and open surgery are detailed for patients with ulcerative colitis and Crohn's disease. Evidence-based comparative results of these surgical approaches are discussed, along with factors that influence patient outcomes. Upcoming new techniques for IBD surgical management, including single-port surgery, are also presented.
