Laparoscopy-assisted combined resection for synchronous gastrointestinal multiple primary cancers

Synchronous triple primary gastrointestinal malignant tumors treated with laparoscopic surgery: A case report

Synchronous gastrointestinal multiple primary tumors including gastric, colonic, and rectal cancers are rare. Moreover, it was a challenge to find an appropriate procedure without negatively impacting the overall outcome. We described the case of a 63-year-old woman who presented with a 4 month history of upper abdominal pain, acid regurgitation, and anemia. Gastroscopy with biopsy suggested early cancer of gastric antrum. Abdominal contrast-enhanced computerized tomography and colonoscopy revealed ascending colon and rectum tumors. She had no family history of malignancy. Endoscopic submucosal dissection was performed for gastric cancer, and the pathological result presented that it was poorly differentiated and invaded into deep submucosa. The laparoscopy-assisted radical surgery combined with distal gastrectomy, right hemicolectomy, and anterior resection of rectum was performed for these three tumors via eight ports and a 7 cm midline upper-abdominal incision. No other perioperative complications were encountered except postoperative ileus. The patient was discharged on the 12th postoperative day. The pathological results revealed gastric cancer (T1N0M0), right colonic cancer (T3N1M0), and rectal cancer (T2N0M0), indicating complete surgical resection. We reported that our laparoscopic approach for synchronous triple primary gastrointestinal malignant tumors was feasible and minimally invasive.

Reduced-port endo-laparoscopic surgery using umbilical zigzag incision for concomitant operations: A case series

•

Umbilical zigzag incision was feasible for concomitant surgery.

•

It could be used for every part of abdominal laparoscopic operations.

•

The umbilical wound was almost invisible after surgery.

Introduction

Recently, use of reduced-port surgery has become widespread; however, it is a difficult operation. Hachisuka et al. developed a method called the umbilical zigzag incision, which enlarges the fascial incision using only an umbilical skin incision. We believe this method will be feasible for concomitant laparoscopic surgery. We report our surgical techniques for concomitant laparoscopic surgery using an umbilical zigzag incision.

Methods

The patient who should receive more than 2 places of abdominal operation were indicated this procedure. In all cases, we made the zigzag incision in the umbilical region. After the linea alba and peritoneum were incised, the wound retractor was inserted through the incision, which enlarges the fascial opening. GelPoint was attached to the wound retractor and the operation was started.

Results

We could create a fascial opening of up to 6 cm with the umbilical zigzag incision, which improves the triangulation of forceps and reduces interference among the trocars. The trocars in the center of the abdomen could be utilized for almost all intraperitoneal operations. This procedure was especially useful in cases that included lymph node dissection because dissection of a malignant tumor is a delicate procedure. Furthermore, extraction of specimens and anastomosis went very smoothly because the fascial incision was large enough such that no extension of the incision was needed. No early or late postoperative complications occurred in any case. Postoperative wounds were clear and therefore patient satisfaction levels were high.

Conclusion

Umbilical zigzag incision may be feasible especially in concomitant laparoscopic surgery.

Clinical outcomes of laparoscopic-assisted synchronous bowel anastomoses for synchronous colorectal cancer: initial clinical experience

The primary aim of this study was to explore the safety and feasibility of laparoscopic-assisted synchronous bowel anastomoses (LSBA) for synchronous colorectal cancer (SCRC). All patients who underwent LSBA for SCRC were retrospectively reviewed and analyzed for clinical and pathological features, technical feasibility and short-term as well as long-term oncological outcomes. Between July 2008 and January 2012, a series of 11 consecutive SCRC patients underwent LSBA. Six patients underwent laparoscopic-assisted right hemicolectomy and anterior resection. Five patients had laparoscopic-assisted right hemicolectomy and sigmoidectomy. There were no intraoperative complications that required open conversions. Mean operation time was 233 (range, 195–285) minutes, and mean estimated blood loss was 224 (range, 100–300) mL. The postoperative course of the patients was uneventful with the mean return to oral intake was 6.9 (range 5–12) days, and mean length of hospital stay was 12.6 (range 9–17) days. All surgical wounds showed good cosmetic outcome, and the mean incision length was 4.1 (range 3.5-5.0) cm. During a median follow-up period of 76 months, no local tumor recurrences were found. LSBA is a potentially feasible and safe procedure for SCRC when performed by an experienced surgeon. Further large clinical controlled trials are warranted to confirm the findings.

Laparoscopy-assisted versus open surgery for multiple colorectal cancers with two anastomoses: a cohort study

Laparoscopy-assisted surgery has been widely accepted in the treatment of colorectal cancer. The aim of the present study was to investigate the feasibility and outcomes of laparoscopy-assisted combined resection for multiple colorectal cancers in comparison to open surgery. We retrospectively reviewed patients with synchronous multiple colorectal cancers who underwent combined resection resulting in two anastomotic sites by either open or laparoscopy-assisted surgery in the University of Tokyo Hospital between April 2005 and March 2015. Nine patients underwent laparoscopic surgery using five ports, whereas 16 underwent open surgery. Blood loss was less (median 65 vs 295 mL, p = 0.0015), but the operative time was longer (median 429 vs 310 min, p = 0.09) in the laparoscopic surgery group than in the open surgery group. No intergroup difference was observed in the number of lymph nodes retrieved (median 32 vs 27, p = 0.50). The frequency of clinically significant postoperative complications was also similar between the two groups. Our results suggest that laparoscopy-assisted combined resection is an acceptable alternative to open surgery for multiple colorectal cancers.
