Colonic delta-shaped anastomosis using linear staplers in laparoscopic colectomy

Short-term Outcomes of Intracorporeal Versus Extracorporeal Totally Stapled Anastomosis after Laparoscopic Colectomy: A Propensity Score-matched Cohort Study

Objectives

To describe detailed surgical techniques for totally stapled intracorporeal anastomosis (TSIA) and determine their feasibility and safety by comparing short-term outcomes with those of conventional totally stapled extracorporeal anastomosis (TSEA).

Methods

In total, 59 consecutive patients who underwent laparoscopic colectomy between June 2018 and August 2021 were retrospectively assessed. Linear staplers were used for all anastomoses. The TSIA and TSEA groups included 23 and 36 patients, respectively. Following a comprehensive description of each surgical technique, propensity score matching analysis was conducted to compare matched groups on the basis of clinicopathological characteristics, surgical and perioperative outcomes, complications, and postoperative inflammatory reactions. After matching, 17 cases each were analyzed in the TSIA and TSEA groups.

Results

Both groups were well matched. The TSIA group had significantly lesser blood loss than did the TSEA group (10 versus 20 mL, p=0.002), although this result was not clinically significant. The skin excision length (4 versus 6 cm, p<0.001) and postoperative hospital stay length (6 versus 7 days, p<0.001) were significantly shorter in the TSIA group than in the TSEA group. Increasing C-reactive protein (CRP) values at 1, 3, and 6 postoperative days were significantly lower in the TSIA group than in the TSEA group (p=0.016, p=0.011, and p=0.012, respectively).

Conclusions

TSIA is a simple, feasible, and efficient surgical technique; compared with TSEA, it is less invasive and associated with lesser blood loss, shorter skin incision lengths, shorter postoperative hospital stays, and lower CRP level increases.

Short-term outcomes of delta-shaped anastomosis versus functional end-to-end anastomosis using linear staplers for colon cancer

BACKGROUND

Several methods are used for reconstruction in colon cancer surgery, including hand-sewn or stapled anastomosis. However, few reports have compared short-term outcomes among reconstruction methods. This study compared short-term outcomes between delta-shaped anastomosis (Delta) and functional end-to-end anastomosis (FEEA).

METHODS

We retrospectively reviewed 1314 consecutive patients who underwent colorectal surgery with FEEA or Delta reconstruction between January 2016 and December 2023. Patients were divided into two groups according to reconstruction by FEEA (F group; n = 1242) or Delta (D group; n = 72). Propensity score matching was applied to minimize the possibility of selection bias and to balance covariates that could affect postoperative complications. Short-term outcomes were compared between groups.

RESULTS

Postoperative complications occurred in 215 patients (17.3%) in F group and 8 patients (11.1%) in D group. Before matching, transverse colon cancer was more frequent (p = 0.002), clinical N-positive status was less frequent (44.1% versus 16.7%, p < 0.001), distant metastasis was less frequent (11.7% versus 1.4%, p = 0.003), and laparoscopic approach was more frequent (87.8% versus 100%, p < 0.001) in D group. After matching, no differences in any clinical factor were evident between groups. Blood loss was significantly lower (28 mL versus 10 mL, p = 0.002) in D group, but operation time and postoperative complication rates were similar between groups.

CONCLUSIONS

Delta and FEEA were both considered safe as reconstruction methods. Further studies are needed to clarify appropriate case selection for Delta and FEEA.

Totally laparoscopic colectomy with intracorporeal anastomosis for colonic liposarcoma: A case report

Liposarcoma is a type of soft tissue sarcoma. Primary colonic liposarcomas are extremely rare. An 86-year-old man with diarrhea and anorexia visited our outpatient clinic at Okayama City Hospital. Colonoscopy and computed tomography imaging revealed a large submucosal tumor in the descending colon with a maximum diameter of approximately 10 cm. He underwent totally laparoscopic left hemicolectomy with intracorporeal anastomosis. The histopathological diagnosis was a well-differentiated liposarcoma without lymph node metastases. The patient's postoperative course was uneventful. We herein report a rare case of totally laparoscopic colectomy with intracorporeal anastomosis in an elderly patient with colonic liposarcoma.

Totally laparoscopic resection using delta-shaped anastomosis of jejunal leiomyosarcoma with intussusception at the angle of Treitz: a case report

Background

A leiomyosarcoma of the gastrointestinal tract is extremely rare. We report a case of jejunal leiomyosarcoma with intestinal intussusception at the angle of Treitz that was successfully treated with laparoscopic resection followed by intracorporeal reconstruction using a delta-shaped anastomosis.

Case presentation

A 54-year-old man was referred to our hospital due to fatigue and loss of appetite. Blood tests showed anemia. Enteroscopy and subsequent enterography using meglumine sodium amidotrizoate showed easily hemorrhagic tumor (10 cm in diameter) in the jejunum just beyond the angle of Treitz. Contrast-enhanced computed tomography revealed jejunojejunal intussusception. Histopathological examination of a biopsy specimen revealed a leiomyosarcoma. Laparoscopic resection of the tumor without reduction of the intussusception was performed. The resected line of the proximal intestine was very close to the ligament of Treitz in the present case. Intracorporeal jejunojejunostomy was completed using a delta-shaped anastomosis, wherein anastomosis was performed between the posterior walls of the proximal and distal jejunums after minimal mobilization around the ligament of Treitz. The patient’s postoperative course was uneventful, and he was discharged at 10 days postoperatively. No recurrence has been observed within 2 years after surgery.

Conclusions

We present a case in which a totally laparoscopic surgery for leiomyosarcoma located at the angle of Treitz with jejunojejunal intussusception was performed successfully.

An experience of total laparoscopic partial colectomy with intracorporeal triangulating anastomosis in an obese patient with descending colon cancer

A 68-year-old woman was transferred to the emergency room of Okayama City Hospital because of worsening epigastric pain. After the examination, she was diagnosed with descending colon cancer, and laparoscopic colectomy was planned. However, exteriorization of the bowels to produce anastomosis was difficult because the rich adipose tissue of the mesocolon hardly stretched, and the abdominal wall was thick as the patient was obese. Therefore, an intracorporeal triangulating end-to-end anastomosis was performed. The colon was divided at 10 cm either side from the tumor using an endoscopic linear stapler. After the resection of the stumps with staples, the posterior walls were tied with stay sutures and then stapled with an endoscopic linear stapler. The anterior wall was stapled twice in the same manner, and the intracorporeal anastomosis was completed. The patient's postoperative course was uneventful. This technique provided an alternative intracorporeal anastomotic technique as troubleshooting in laparoscopic colectomy.
