Laparoscopic distal pancreatectomy for pancreatic tail cancer in a 100-year-old patient.

We present the case of a 100-year-old man with no specific symptoms. Computed tomography (CT) revealed a 34 mm tumor in the pancreatic tail, which was diagnosed as pancreatic cancer by biopsy. CT and magnetic resonance imaging showed that the tumor was resectable, and there were no noncurative factors on staging laparoscopy (cT3N0M0: cStage IIA). His performance status was good, and hypertension was the only comorbidity. A cardiologist, respiratory physician, and anesthesiologist examined the patient and determined that his condition was suitable for surgery. His postoperative predicted mortality rate was 0.9% using the American College of Surgeons risk calculator. We administered synbiotics and nutrients before surgery and introduced preoperative rehabilitation to improve his activities of daily living (ADL) as well as respiratory training to prevent postoperative pneumonia. Regarding the invasiveness of the surgery, we performed laparoscopic distal pancreatectomy with D1 lymphadenectomy. The patient was discharged on postoperative day 17, without any major complications. When performing pancreatectomy in older adults, it is important to fully assess preoperative tolerance and perioperative risk and prevent worsening of ADL by introducing nutritional therapy and rehabilitation.

Repair using the pectoralis major musculocutaneous flap for refractory anastomotic leakage after total esophagectomy.

BACKGROUND: The pectoralis major musculocutaneous flap (PMMF) is a pedicled flap often used as a reconstruction option in head and neck surgery, especially in cases with poor wound healing. However, applying PMMF after esophageal surgery is uncommon. We report here, the case of a successfully repaired refractory anastomotic fistula (RF) after total esophagectomy, by PMMF. CASE PRESENTATION: A 73-year-old man had a history of hypopharyngolaryngectomy, cervical esophagectomy, and reconstruction using a free jejunal graft for hypopharyngeal carcinosarcoma at the age of 54. He also received conservative treatment for pharyngo-jejunal anastomotic leakage (AL), then postoperative radiation therapy. This time, he was diagnosed with carcinosarcoma in the upper thoracic esophagus; cT3rN0M0, cStageII, according to the Japanese Classification of Esophageal Cancer 12th Edition. As a salvage surgery, thoracoscopic total resection of the esophageal remnant and reconstruction using gastric tube via posterior mediastinal route was performed. The distal side of the jejunal graft was cut and re-anastomosed with the top of the gastric tube. An AL was observed on the 6th postoperative day (POD), and after 2 months of conservative treatment was then diagnosed as RF. The 3/4 circumference of the anterior wall of the gastric tube was ruptured for 6 cm in length, and surgical repair using PMMF was performed on POD71. The edge of the defect was exposed and the PMMF (10 × 5 cm) fed by thoracoacromial vessels was prepared. Then, the skin of the flap and the wedge of the leakage were hand sutured via double layers with the skin of the flap facing the intestinal lumen. Although a minor AL was observed on POD19, it healed with conservative treatment. No complications, such as stenosis, reflux, re-leakage, were observed over 3 years of postoperative follow-up. CONCLUSIONS: The PMMF is a useful option for repairing intractable AL after esophagectomy, especially in cases with large defect, as well as difficulties for microvascular anastomosis due to previous operation, radiation, or wound inflammation.

Aqueous Povidone-Iodine Versus Normal Saline For Intraoperative Wound Irrigation on The Incidence of Surgical Site Infection in Clean-Contaminated Wounds After Gastroenterological Surgery: A Single-Institute, Prospective, Blinded-Endpoint, Randomized Controlled Trial.

OBJECTIVE: This trial evaluated the superiority of intraoperative wound irrigation (IOWI) with aqueous povidone-iodine (PVP-I) compared with that with saline for reducing the incidence of surgical site infection (SSI). BACKGROUND: IOWI with aqueous PVP-I is recommended for the prevention of SSI by the World Health Organization and the Centers for Disease Control and Prevention, although the evidence level is low. METHODS: This single institute in Japan, prospective, randomized, blinded-endpoint trial was conducted to assess the superiority of IOWI with aqueous PVP-I in comparison with IOWI with saline for reducing the incidence of SSI in clean-contaminated wounds after gastroenterological surgery. Patients 20 years or older were assessed for eligibility, and the eligible participants were randomized at a 1:1 ratio using a computer-generated block randomization. In the study group, IOWI was performed for 1 minute with 40 mL of aqueous 10% PVP-I before skin closure. In the control group, the procedure was performed with 100 mL of saline. Participants, assessors, and analysts were masked to the treatment allocation. The primary outcome was the incidence of incisional SSI in the intention-to-treat set. RESULTS: Between June 2019 and March 2022, 941 patients were randomized to the study group (473 patients) or the control group (468 patients). The incidence of incisional SSI was 7.6% in the study group and 5.1% in the control group (risk difference 0.025, 95% CI -0.006 to 0.056; risk ratio 1.484, 95% CI 0.9 to 2.448; P =0.154). CONCLUSION: The current recommendation of IOWI with aqueous PVP-I should be reconsidered.

Modified keyhole plus technique with partial release of posterior rectus sheath for parastomal hernia repair after ileal conduit.

Parastomal hernia (PH) is a common complication of ileal conduit diversions. The Sugarbaker technique has a lower recurrence rate than the keyhole (KH) technique and is typically preferred. However, it may not be feasible in some cases because of anatomical features including the length of the conduit and torsion of the ureter. An 80-year-old woman with complaints of abdominal distention was diagnosed with PH 5 years after radical cystectomy. Computed tomography revealed a 90 × 20-mm muscular layer defect on the cranial side of the ileal conduit. Therefore, we performed the KH technique with intracorporeal closure of the defect using a relief incision of the posterior rectus sheath, avoiding the possibility of torsion of the ureteral ileal anastomosis. No hernia recurrence was observed at postoperative 10 months. The proposed KH plus technique may be an effective method for PH after ileal conduit diversion, thus preventing urinary complications.

Laparoscopic repair of suprapubic incisional hernia using a modified transabdominal partial extraperitoneal technique.

INTRODUCTION: Herein, we describe a novel technique for suprapubic incisional hernia repair using a modified transabdominal partial extraperitoneal technique in four patients. MATERIALS AND SURGICAL TECHNIQUE: We implemented four-trocar placement to achieve a coaxial setting for the pubic bone. The pubic bone and Cooper's ligament were exposed by an incision dorsal to the hernial orifice, and the bladder was mobilized as an inferior peritoneal flap. The retropubic space was dissected approximately 5 cm from the hernial defect and this was closed with an intracorporeal non-absorbable barbed suture. A mesh was introduced into the intra-abdominal cavity, positioned to cover the closed defect, and tied to Cooper's ligament, the pubic bone, and rectus muscles. The dissected peritoneal flap was reattached to the abdominal wall by tacking and suturing. DISCUSSION: The modified transabdominal partial extraperitoneal technique for suprapubic incisional hernia repair may contribute to decreased recurrence and seroma formation.
